Forecasting of the Traffic Situation in the Hannover Region
The main requirement of road traffic participants is to know the current traffic situation. Such data is typically obtained from routing services where the time of many different individual trips is taken into account.
In the context of Data4UrbanMobility tools were developed that allow to predict the traffic situation based on such time series data. The following figure presents an interface to visualize typical time series patterns as well as outliers present in the data:

The prediction of the traffic situation is made available in the form of a map based interface for the end user:

Data4UrbanMobility Data Protection Regulation
The work on the Data4UrbanMobility data protection regulation is completed. The document is publicly available and can be found here.
First Version of MiC-App Available
A first version of the novel MiC-App (Move in the City) App is now available for D4UM-associates as well as a protected group of public users. The mobile MiC-App is a tool to gather data.
MiC was developed by the Institute for Sustainable Urbanism at the University of Braunschweig and the Projektionisten GmbH. MiC links the growing awareness of digital citizen rights with the potential of evaluation big datasets. Therefore MiC gives the opportunity to citizen to actively participate in a citizen science project to take part in the development of the mobility of the feature.
MiC gathers data of the users movement, where the user has the about which data should be recorded. All data is pseudonymised such that the privacy of the contributing citizen is ensured.
Current Status:
In the first version of the app, the user can easily start and end the tracking of his/her movement. It is worth to point out, that the user decides when he is tracked and when not. A summary of his/her activity is available for the user as well as the opportunity to issue feedback or even delete all of his contributed data.

Updated System with Dashboard V2
With the new version of our system, the dashboard will provide even more insights into the impact of public events on the traffic situation.

The coloring and labels let us easily distinguish between the different type of events. By clicking on the label we show the typically affected subgraph for that event type. This allows the user to check what specific routes are typically affected by an event at that location.

Examples: Visualisation of a concert and a football game.

In addition, the graph at the top right gives additional information on how big the impact around the events start time tends to be.
{API}
We enriched the api endpoints with additional information from the data models that were developed as part of the research efforts.
D4UM App Version 1.0
We just released the first Version of the D4UM App. Every project member now has access to the application and can try out its features. Let’s quickly go over some of its main features.
The EFA integration (EFA is a routing engine covering Lower Saxony and Bremen ) allows for quick access to tip information using all available public transport options. Our focus, when designing the application, was on quick and easy navigation to provide a simple and easy to use trip planning tool.
Departures and Connections
On the departure screen we show the user the closes stops for public transportation in his immediate vicinity. On the connection screen the user can fill in his desired starting location( either an address or an existing stop ) and destination and query for what connections are available to him. The provided information contains real time data , meaning we are able to visualized delays for any given connection.

Map
On the map screen you can see and or find all available stops of public transportation. This allows for providing the user with a great way to find out what stops are available in their city. By clicking on any of the shown stops will open the departure screen and provide you with the information mentioned above. To better visualize a selected connection, we show the route you plan to travel on the map.

Menu / Settings
Additional features can be found in the settings menu of the application. Here you can find settings that allow you to customize your routing results for both the departures and connection screen. The best way to let us know what you think about the application is to use the feedback module. This can be found here as well. First click on the emoji that best describe how you feel about the app. And then put in any additional information or ideas or thoughts you may have. Now what is left is just to press send and you will send us an email.
We look forward to hearing from you.

Quantification and Prediction of Impact of Public Events
Current Data4UrbanMobility research results allow for measuring and prediction of spatial impact on road traffic of public events. Connected, affected street segments nearby public events are identified to measure the spatial impact. The approach is depicted in the following figure:

An event is marked as yellow dot, affected streets in red and the measured impact in dark blue. Moreover, an approach making use of machine learning algorithms was developed to predict the impact determined in this way, resulting an error-reduction of up to 40% when compared to existing state-of-the-art approaches.
D4UM – Platform V1 Released
The first version of the Data4UrbanMobiltiy platform has been released. The platform was designed and implemented following a 3-tier-architecture. The platform provides RESTfull Web services for mobility applications like dashboards or mobile apps. As a demonstration, an interactive map application has been developed that visualizes the spatial impact of public events. The following figure shows a screenshot of the application.

The figure shows 4 public events in the city of Hannover. The colors represent different types of public events (e.g. concerts, fairs, sport events). The circles visualize the spatial impact on road traffic caused by the public events.
Comprehensive Set of Requirements
The Data4UrbanMobility analysis of requirements includes requirements of the application partners Region Hannover (RH) and Wolfsburg AG (WAG) as well as non functional requirements. The requirements were collected by MOMA. The L3S derived research question for data analysis which are based on the requirements of RH and WAG. The research question address especially the information needs of end-users.
The current research questions particularly include
- Automated verification of traffic warnings and prediction of their impact
- Identification of events and prediction of their impact
- Investigation of correlation of road traffic data, public transportation query logs, traffic warnings and twitterfeeds
- Determination of optimal traveling timepoints
Growing Data Collection
ISU create a comprehensive data matrix containing potential source of mobility related data. The Data4UrbanMobility data model describes all project relevant data sets and sets them into context. This makes the data available in a unified manor for both analysis and applications. The selected data sources were transformed according to the Data4UrbanMobility data model by L3S. The data quality of selected data sources (i.e. public transportation query logs and road traffic data) was examined.
Tools for extracting the relevant information from the datasets were developed to enable the integration of the datasets.
- Street and graph extraction from OpenStreetMap
- Bulkloader for public transportation queries
- Integration of “Zentrales Haltestellen Verzeichniss” (central registry of public transportation stops)
The current collection (December 12th 2017) contians
EFA-Logs: 17 million public transportation queries
Road traffic data: 174 thousand street sements with a frequency of 15 minutes
GTFS-data: 90 thousand. public transportation stops, 2.6 thousand routes
Weather: Radolan “Regenraster” (rain grid)
Twitter: 2,5 Mio. Tweets starting at June 2017
OSM: 440 thousand streets
Events: 21 thousand public events (August 14th 2016-July 17th 2018)
Traffic warnings: 13 thousand warning (since June 2017)
Visualization of Public Transportation Information
In order to allow intuitive analytics of public transportation information, the PROJEKTIONISTEN (PROJ) developed a dashboard web application. First prototypes visualize queries addressed to the regional timetable information system EFA (www.efa.de). The prototypes serve as foundations for exploration analyses as well as the implementation of future versions of the dashboard. The following figure shows an integrated visualization of the most frequent origins and destinations of the queries.

Analysen der EFA-Logs
Analysis of EFA Public Transportation Query Logs
Analyses regarding the impact of public events on public transportation are currently conducted to address early research questions. To this extend, explorative data analyses of the impact of major public events such as football games and medium sized events such as concerts were conducted. Visual analytics were used as a first step towards comprehensive analyses, which show start-like patterns for city center which identify mobility hubs of central importance.

The figure shows the direct connection between origin and destination of public transportation queries. Darker colors correspond to more frequent queried trips. Star-like pattern identify the central train station and the central metro station.
Analyses of single stations reveal weekday dependent patterns.

The figure depicts the average number of queries with the destination “Hannover Stadionbrücke”. Differences emerge between Weekends and workdays.
The impact of public events on the queries can be visualized as well.

The figure shows the number of queries with the Destination “Hannover Stadionbrücke” for Wednesday, April 26th 2017 (orange) as well as the average number of queries on a Wednesday for the same destination. On this day a concert took place in venue nearby. The concert start at 8 pm. The significant deviations between 5 pm and 7 pm is highly likely to be caused by visitors of the concert. This shows that public transportation queries are a valuable information source to investigate the impact of public events on mobility infrastructure.

Rapidly increasing chance of record UK summer temperatures. Kay, Gillian; Dunstone, Nick; Smith, Doug M.; Brown, Simon J.; Kent, Chris; Lockwood, Julia F.; Scaife, Adam A. (2025). n/a(n/a)
Abstract The UK recorded its first exceedance of 40°C in July 2022. To assess the current chance of recurrence, we use a large climate model ensemble approach and find the 2023 return period to be 1-in-24 years (1/20–1/29 years confidence interval). However, the likelihood of 40°C has been accelerating and we estimate a 50–50 chance of another exceedance in the next 12 years, 4 years earlier than in a static 2023 climate. Far higher temperatures – over 45°C – and more sustained heatwaves may be possible today. Improved understanding of baseline exposure to temperature extremes could inform strategic heatwave preparation.

Forests are a significant part of the surrounding landscape, and every management decision in the forest also affects the landscape, and vice versa. Management decisions in the surrounding landscape also affect the forests. Thus, a framework of integrated decision support systems (DSS) is needed to appropriately address all objectives of sustainable forest management in the landscape by linking all mutual relations between forests and the surrounding landscape. Such an integrated DSS framework will require the consideration of information and approaches from different rural and land-use activities and sectors. In this context, juxtaposition and integration of the knowledge from DSS (developed for farming, animal husbandry, forestry, ecosystem management, etc.) will be an excellent starting point for advancing toward an integrated system for sustainable assessing the provision of ecosystem service at landscape scale, including provision of resources for bio-based economic activities, protection and regulation, or cultural services. The main aim of this action is to establish a research network to facilitate the conceptualization and development of new methodological approaches in DSS, including important relationships between forests and landscapes. The emphasis is on screening, evaluating, and proposing existing and future tools to support holistic planning approaches to increase sustainable forest management, considering various ecosystem services and products addressing the associated risks and uncertainties.
Adaptation and Mitigation Strategies of the Populations of Abuja and Ouagadougou in West Africa to the Various Impacts of Extreme Climate Events in Urban Areas. Gadiaga, Aliou; Okhimamhe, Appollonia Aimiosino; Thiel, Michael; Neya, Oble (2025). 13(7) 26.
Urban settings in West Africa are increasingly experiencing extreme weather events, such as heat waves, floods, and windstorms. Climate phenomena exacerbated by global climate change are not unique to this region but reflect a broader trend of worldwide environmental changes. However, how local communities in tropical cities in the global south adapt to these extreme events is not fully understood. Understanding local adaptation strategies is crucial in enhancing our ability to develop context-specific policies that address climate vulnerabilities. This study aimed to analyse the adaptation and mitigation strategies employed by the urban residents of Abuja and Ouagadougou in response to recurrent floods, heat waves, and windstorms. To investigate adaptation and mitigation strategies for climate change in urban areas, this study collected quantitative data from a sample of 840 households in Abuja and 840 households in Ouagadougou. The results revealed that the participants of each city used different strategies to adapt to and mitigate heat waves, floods, and windstorms. However, the level of adoption of these measures differed among the respondents. The findings revealed a low level of adoption of climate change mitigation measures. Context-specific policies must prioritise strengthening local adaptation strategies, addressing socioeconomic disparities, and fostering urban design solutions tailored to each city’s unique environmental and infrastructural challenges.
Determination of Jupiter’s primordial physical state. Batygin, Konstantin; Adams, Fred C. (2025). 9(6) 835–844.
The formation and early evolution of Jupiter played a pivotal role in sculpting the large-scale architecture of the Solar System, intertwining the narrative of Jovian early years with the broader story of the Solar System’s origins. The details and chronology of Jupiter’s formation, however, remain elusive, primarily due to the inherent uncertainties of accretionary models, highlighting the need for independent constraints. Here we show that, by analysing the dynamics of Jupiter’s satellites concurrently with its angular-momentum budget, we can infer Jupiter’s radius and interior state at the time of the protosolar nebula’s dissipation. In particular, our calculations reveal that Jupiter was 2 to 2.5 times as large as it is today, 3.8 Myr after the formation of the first solids in the Solar System. Our model further indicates that young Jupiter possessed a magnetic field of B♃† ≈ 21 mT (a factor of ~ 50 higher than its present-day value) and was accreting material through a circum-Jovian disk at a rate of \($$\)\dotM=1.2\($$\)–2.4 M♃ Myr−1. Our findings are fully consistent with the core-accretion theory of giant-planet formation and provide an evolutionary snapshot that pins down properties of the Jovian system at the end of the protosolar nebula’s lifetime.
Cataracts: A Review. Chen, Stephanie P.; Woreta, Fasika; Chang, David F. (2025). 333(23) 2093.
Importance Age-related cataract, defined as progressive opacification or clouding of the eye’s natural lens, is a leading cause of visual disability and blindness. Cataract surgery is one of the most commonly performed procedures in high-income countries. More than 3.5 million cataract operations are performed annually in the US. Observations Older age is the primary risk factor for cataracts, with approximately two-thirds of the population older than 80 years affected. As the population ages, the number of people with cataracts in the US is expected to increase to 50 million by 2050. Additional risk factors for cataracts include a hereditary or genetic predisposition, certain medications (corticosteroids), ocular trauma, significant UV exposure or radiation therapy, and certain medical conditions such as uncontrolled diabetes, retinitis pigmentosa, Down syndrome, and congenital rubella. Painless, progressive blurring of vision and visual glare are common symptoms of cataracts. Cataracts are diagnosed during an eye examination by an ophthalmologist or optometrist. Surgery to remove the cataract and implant a permanent intraocular lens (IOL) is indicated if visual impairment impedes activities of daily living and is associated with lower rates of falls (>30%) and dementia (20%-30%). Most cataract operations are performed with topical anesthesia. Therefore, patients do not require preoperative general medical testing such as bloodwork or electrocardiogram, and do not need to discontinue anticoagulants for cataract surgery. Systemic α1-adrenergic antagonists for symptomatic benign prostatic hyperplasia, such as tamsulosin, increase the risk of surgical complications and some ophthalmologists temporarily discontinue the drug preoperatively. Intraocular antibiotics, such as moxifloxacin or cefuroxime, delivered intraoperatively have reduced the rates of sight-threatening postsurgical endophthalmitis from 0.07% to 0.02%. In addition to reversing and preventing progressive vision loss, cataract surgery can reduce dependence on eyeglasses. These optional refractive benefits are achieved with advanced technology IOL designs, such as multifocal IOLs. However, multifocal and other advanced technology refractive IOLs are associated with increased costs that are not covered by medical insurance. Conclusions and Relevance Cataracts are common among older adults and may cause visual disability and blindness without treatment. Cataract surgery reverses and prevents progressive vision loss, and advanced technology lens implants facilitate reduced dependence on eyeglasses.

Fingerprints of AMOC Decline Are Sensitive to External and Mechanistic Forcing. McMonigal, Kay; Larson, Sarah M.; Gervais, Melissa; Klavans, Jeremy M.; He, Chengfei; Cane, Mark A.; Corti, Susanna; Bellomo, Katinka (2025). 52(12) e2025GL116307.
Abstract The Atlantic meridional overturning circulation (AMOC) plays a crucial role in past, present, and future climate, and there is substantial interest in using sea surface temperature (SST) as a fingerprint of past AMOC strength. Using a hierarchy of climate model ensembles, we find that the decline in AMOC, and its SST fingerprint within the North Atlantic warming hole region, are sensitive to external forcing level and wind driven ocean forcing. Once external forcing reaches a level at which sea ice melt increases the Labrador Sea vertical salinity gradient, localized cooling and resulting expansion of the sea ice edge decrease vertical mechanical stirring. Under greenhouse gas only forcing, this mechanism plays a large role and under SSP3.70 forcing, it plays a relatively minor role due to larger buoyancy forcing. This implies that an AMOC fingerprint developed from one simulation or external forcing level cannot be applied to other scenarios.
Resting Ca2+ fluxes protect cells from fast mitochondrial fragmentation, cell stress responses, and immediate transcriptional reprogramming. Fecher, Caroline; Sodmann, Annemarie; Schlott, Felicitas; Jaepel, Juliane; Schmitt, Franziska; Lengfelder, Isabella; Bischler, Thorsten; Nieswandt, Bernhard; Winklhofer, Konstanze F.; Blum, Robert (2025). 82(1) 238.
Homeostatic calcium ion (Ca2+) fluxes between the endoplasmic reticulum, cytosol, and extracellular space occur not only in response to cell stimulation but also in unstimulated cells. Using murine astrocytes as a model, we asked whether there is a signaling function of these resting Ca2+ fluxes. The data showed that endoplasmic reticulum (ER) Catexttwosuperior⁺ depletion, induced by sarcoplasmic/endoplasmic reticulum Catexttwosuperior⁺-ATPase (SERCA) inhibition, resulted to prolonged Catexttwosuperior⁺ influx and mitochondrial fragmentation within 10 to 30 min. This mitochondrial fragmentation could be prevented in Ca2+-free medium or by inhibiting store-operated Ca2+ entry (SOCE). Similarly, attenuation of STIM proteins, which are vital ER Ca2+ sensors, protected mitochondrial morphology. On the molecular level, ER Ca2+ depletion, achieved either by removing extracellular Ca2+ or through acute SERCA inhibition, led to changes in gene expression of about 13% and 41% of the transcriptome within an hour, respectively. Transcriptome changes were associated with universal biological processes such as transcription, differentiation, or cell stress. Strong increase in expression was observed for the transcription factor ATF4, which is under control of the kinase PERK (EIF2AK3), a key protein involved in ER stress. Corroborating these findings, PERK was rapidly phosphorylated in Ca2+-free medium or after acute pharmacological inhibition of SOCE. In summary, resting, homeostatic Ca2+ fluxes prevent immediate-early cell stress and transcriptional reprogramming.

Shape-shifting in relative wing length of juvenile shorebirds: no evidence of developmental temperatures driving morphological changes. Ryding, Sara; McQueen, Alexandra; Symonds, Matthew R.E.; Tattersall, Glenn J.; Wader Study Group, Victorian; Wader Studies Group, Australasian; Rogers, Danny I.; Atkinson, Robyn; Jessop, Roz; Hassell, Chris J.; Christie, Maureen; Ross, Tobias A.; Klaassen, Marcel (2025). n/a(n/a) e07801.
Morphological changes concurrent with climate change are increasingly identified in birds, often through decreasing body size and increasing appendage size. Such changes could have thermoregulatory implications, through the improved surface area to body ratio they provide. Due to the role of bird wings in thermoregulation, wing length relative to body mass may be changing as another form of shape-shifting, where increased relative wing length may facilitate increased heat loss as climates warm. We investigated changes in relative wing length on a dataset of nearly 20 000 juvenile shorebirds from 11 species over the past four decades, to determine changes in morphology and whether these are linked to developmental temperatures. Overall, across species, we found that relative wing length increased across the 43-year study period in populations migrating to tropical northern Australia but not in those migrating to temperate southern Australia. Furthermore, we found that changes in relative wing length were not driven by immediate responses to high temperature at the breeding ground during juvenile growth. These results may suggest that relative wing length increases occur in shorebirds occupying already warm climates, where they might potentially be more thermally challenged under further warming, but that such changes are not occurring through plastic mechanisms during development.

Quo Vadis CKKS: Comparison of the Realization of Basic Mathematical Functions for the Homomorphic Cryptosystem CKKS using De Bello and Polynomial Approximations. Prantl, Thomas; Horn, Lukas; Engel, Simon; Bauer, André; Kounev, Samuel (2025). 93
As data storage and processing increasingly shift to the cloud, the risk of data breaches also rises. One way to address this is using Homomorphic Encryption (HE), which allows for data processing while the data remains encrypted, unlike traditional methods. However, current HE libraries support only addition and multiplication, requiring users to implement other mathematical functions themselves. To this end, we developed and analyzed basic mathematical functions in a previous work. Since polynomial approximations are more common in HE, this paper expands on that by examining and comparing polynomial approximations of these functions with the previously implemented methods. Our findings indicate that while polynomial approximations offer the benefit of low multiplication depth, the previously implemented methods generally outperform them in most scenarios despite their higher computational cost.
The First Early Evidence of the Use of Browser Fingerprinting for Online Tracking. Liu, Zengrui; Dani, Jimmy; Cao, Yinzhi; Wu, Shujiang; Saxena, Nitesh in WWW ’25 (2025). 4980–4995.
While advertising has become commonplace in today's online interactions, there is a notable dearth of research investigating the extent to which browser fingerprinting is harnessed for user tracking and targeted advertising. Prior studies only measured whether fingerprinting-related scripts are being run on the websites but that in itself does not necessarily mean that fingerprinting is being used for the privacy-invasive purpose of online tracking because fingerprinting might be deployed for the defensive purposes of bot/fraud detection and user authentication. It is imperative to address the mounting concerns regarding the utilization of browser fingerprinting in the realm of online advertising.This paper introduces "FPTrace" (fingerprinting-based tracking assessment and comprehensive evaluation framework), a framework to assess fingerprinting-based user tracking by analyzing ad changes from browser fingerprinting adjustments. Using FPTrace, we emulate user interactions, capture ad bid data, and monitor HTTP traffic. Our large-scale study reveals strong evidence of browser fingerprinting for ad tracking and targeting, shown by bid value disparities and reduced HTTP records after fingerprinting changes. We also show fingerprinting can bypass GDPR/CCPA opt-outs, enabling privacy-invasive tracking.In conclusion, our research unveils the widespread employment of browser fingerprinting in online advertising, prompting critical considerations regarding user privacy and data security within the digital advertising landscape.
Can We Trust Machines? A Critical Look at Some Machine Translation Evaluation Metrics. Zayyanu, Muhammad; Abbas, Zaki Nazir Ibrahim L. B. S. Papadima-Sophocleous (ed.) (2025). 44–49.
The current paper describes a first experiment in the use of TED talks and open tagging exercises to train higher-level comprehension skills, and of automatic logging of the student’s actions to investigate the student choices while performing analytical tasks. The experiment took advantage of an interactive learning platform – LearnWeb – that integrates TED talk videos and transcripts and enriches them with tagging features and a data logging system. The data collected offered an answer to the following questions: Which of the three tasks was perceived by the students as more difficult? How was each task faced by the students? How did the logs contribute to an understanding of the students’ approaches to the tasks? The experiment also suggested ideas for further development of LearnWeb’s log features.
One decade of institutional scientific output and impact in West Africa - The West African Science Service Centre on Climate Change and Adapted Land Use (WASCAL). Schönbrodt-Stitt, Sarah; Kleemann, Janina; Fürst, Christine; Vlek, Paul; Koné, Daouda; Ogunjobi, Kehinde; Thiel, Michael (2025). 56 13.
In the frame of climate change, Africa belongs to the regions with low capacities to cope with the negative effects. Local capacities in education and research need to be strengthened to increase the regions’ social-ecological resilience and provide long-term environmental security for people. Foreign investors in this endeavour are often interested in the output and impact of their investments in order to identify the potentials for further improvements and commitments. In our study, we have focused on an international institution that is actively contributing to improve climate change research in West Africa, called WASCAL (West African Science Service Centre on Climate Change and Adapted Land Use). Taking the 10-year anniversary of WASCAL as the occasion for an assessment of the scientific output, a comprehensive systematic literature review for the time span 2012–2022 of peer-reviewed scientific publications related to WASCAL was conducted. In total, 315 high-quality papers published in 149 different peer-reviewed journals were identified. Globally, WASCAL is well connected, shown by joint publications from 58 different countries. Within West Africa, especially Burkina Faso (107 publications) and Ghana (86 publications) were represented with high levels of (co-)authorships. One of the main research areas of WASCAL is climate modelling which was reflected in the findings. Relatively underrepresented in the frame of WASCAL-related publications were studies from social sciences. In addition, more research should be conducted on the multifaceted topics of food security and urban planning. WASCAL could also contribute further to the emerging research field of tropical medicine and parasitology due to the threat to human health and food security resulting from environmental and climate change.
Transport Mode Choice for Disaggregated Mobility Demand Generation. Strobel, Leo; Pruckner, Marco (2025). 13 86848–86862.
The OpenStreetMap Mobility Demand Generator (OMOD) is an open-source tool that creates realistic synthetic mobility demand for any region in Germany. The tool focuses on ease of use and fast prototyping, and requires only OpenStreetMap (OSM) data from the user. In this work, we introduce the aspect of traffic mode choice into OMOD. We utilize a two-stage multinomial logit model that works with precise origin-destination coordinates and exact departure times to determine each trip’s travel time and other level-of-service attributes based on network information acquired from OpenStreetMap and GTFS public transit schedules. We evaluate the performance of our model in two stages: first, directly on a separate test set of the household travel survey, and second, for a microsimulation of three different German cities. On the household travel survey, we reach accuracies between 64.3 % and 77.8 % with well-fitted calibration curves. Achieving high performance in the microsimulation is more difficult due to the existence of downstream errors. Nonetheless, we achieve close fits for all modes with the exception of the car passenger mode.

POLYLOGARITHM VALUES AT A GOLDEN RATIO-BASED ARGUMENT. Harr, Tristen (2025, June).
The research paper by Tristen Harr introduces and analyzes a novel complex constant, ΛG1, which is derived from inverse powers of the golden ratio, ϕ. The author defines the constant as ΛG1=T+iJ, where T=1/(2ϕ) and J=1/(2ϕ2), and proves it is an algebraic number with a magnitude less than one. This property validates its use as an argument in the Polylogarithm function, Lis(z). Based on high-precision numerical evaluations for the Dilogarithm (s=2) and Trilogarithm (s=3) cases, the paper conjectures that the resulting values, Lis(ΛG1), are transcendental for all integers s≥2 and do not exist within the field extension Q(π,ln(2),ϕ). This investigation is partly motivated by potential applications in the study of quasicrystals, where the golden ratio plays a foundational role.
Harnessing AI for Data Privacy through a Multidimensional Framework. Mahendra, Prateik P. Mahendra (ed.) (2025). (Vol. 15) 1–20.
Traditional approaches have failed to keep up with privacy requirements as AI and ML systems increasingly interact with vast, sensitive data sets. Currently, most solutions treat privacy as strictly a technical problem or legal checkbox, but rarely both. The presented work this paper uses a multidimensional scheme that serves to reframe data privacy as a fundamental design principle through the integration of four key perspectives: technical structure, regulatory fit, organizational preparedness, and ethical responsibility. We assess such privacy preserving solutions, federated learning, secure multiparty computation, differential privacy, among others, against the real-world constraints such as scalability, latency and compliance. With cross-sector case study and comparative analysis we illustrate that hybrid context-aware deployments can bridge the theory-practice gap. Our contribution is more than just a toolkit: it is a systems-level implementation that allows businesses and organizations to operationalize privacy while embracing innovation. Such work is necessary for future empirical studies to provide a grounded approach to the development of AI systems that are high performing, yet privacy preserving.
Cosmology using numerical relativity. Aurrekoetxea, Josu C.; Clough, Katy; Lim, Eugene A. (2025). 28(1) 5-.
This review is an up-to-date account of the use of numerical relativity to study dynamical, strong-gravity environments in a cosmological context. First, we provide a gentle introduction into the use of numerical relativity in solving cosmological spacetimes, aimed at both cosmologists and numerical relativists. Second, we survey the present body of work, focusing on general relativistic simulations, organised according to the cosmological history—from cosmogenesis, through the early hot Big Bang, to the late-time evolution of the universe. We discuss the present state-of-the-art, and suggest directions in which future work can be fruitfully pursued.
Citizen science illuminates the nature of city lights. Nachtlichter, Team (2025). 2 496–505.
The image of Earth at night from space, with its constellations of cities, has become iconic. However, our understanding of the source and scale of artificial light emissions is still in the dark, hampering urban environmental protection efforts. In 2021, our citizen scientists used the Nachtlichter app to count and classify 234,044 light sources across a 22-km2 area, primarily in Germany. We show that such a dataset can be used to translate space-based radiance observations to the more understandable unit of installed lights per km2 on the ground. We find that in German city centers, more total light sources are used for advertising and aesthetic purposes than for street lighting. Furthermore, we estimate that 78thinspacetextpmthinspace3thinspacemillion individual light sources remain illuminated at midnight across Germany, highlighting great potential for mitigation. These findings not only offer direct knowledge for artificial light research but also serve as a practical resource for policymakers to mitigate urban light pollution.

An Optimized Energy-Efficient Hello Routing Protocol for Underwater Wireless Sensor Network. S, Vinayprasad M; N, Jayaram M in Communications in Computer and Information Science, M. Helfert, D. Ferguson, V. M. Muñoz, J. S. Cardoso (eds.) (2025). (Vol. 17) 57–72.
Underwater wireless sensor network (UWSN) is a great technological advancement for numerous implementations, such as pollution monitoring tsunami offshore gas and oil reservoirs. Coherent routing with optimal energy use is necessary to send received data from the sensor to the sink hub. The distinct characteristics of the underwater circumstances make designing routing protocols problematic. Therefore, a novel Dove-based Hello Routing Protocol (DbHRP) was proposed to increase the data broadcasting rate within low energy. The nodes are initially initialized, and their positions are estimated. Subsequently, the dove function finds the SP(SP) from source to target, and the status of the target node is analyzed for data packet transmission. The data transfer function is planned based on the destination node's initial request priority if the target node needs to receive more data from a different source hub. Finally, the UWSN communication parameters were measured and compared with prevailing models.
SARM1 loss protects retinal ganglion cells in a mouse model of autosomal dominant optic atrophy. Ding, Chen; Ndiaye, Papa S.; Campbell, Sydney R.; Fry, Michelle Y.; Gong, Jincheng; Wienbar, Sophia R.; Gibbs, Whitney; Morquette, Philippe; Chao, Luke H.; Do, Michael Tri H.; Schwarz, Thomas L. (2025). 135(12)
Autosomal dominant optic atrophy (ADOA), the most prevalent hereditary optic neuropathy, leads to retinal ganglion cell (RGC) degeneration and vision loss. ADOA is primarily caused by mutations in the optic atrophy type 1 (OPA1) gene, which encodes a conserved GTPase important for mitochondrial inner membrane dynamics. To date, the disease mechanism remains unclear, and no therapies are available. We generated a mouse model carrying the pathogenic Opa1R290Q/+ allele that recapitulated key features of human ADOA, including mitochondrial defects, age-related RGC loss, optic nerve degeneration, and reduced RGC functions. We identified sterile alpha and TIR motif containing 1 (SARM1), a neurodegeneration switch, as a key driver of RGC degeneration in these mice. Sarm1 KO nearly completely suppressed all the degeneration phenotypes without reversing mitochondrial fragmentation. Additionally, we show that a portion of SARM1 localized within the mitochondrial intermembrane space. These findings indicated that SARM1 was activated downstream of mitochondrial dysfunction in ADOA, highlighting it as a promising therapeutic target.

Conceptual Mapping of Controversies. Draude, Claude; Dürrschnabel, Dominik; Hirth, Johannes; Horn, Viktoria; Kropf, Jonathan; Lamla, Jörn; Stumme, Gerd; Uhlmann, Markus (2024).
With our work, we contribute towards a qualitative analysis of the discourse on controversies in online news media. For this, we employ Formal Concept Analysis and the economics of conventions to derive conceptual controversy maps. In our experiments, we analyze two maps from different news journals with methods from ordinal data science. We show how these methods can be used to assess the diversity, complexity and potential bias of controversies. In addition to that, we discuss how the diagrams of concept lattices can be used to navigate between news articles.

Ptolemy’s table of chords: Implications considered and discussed. Schrausser, Dietmar (2024). 2024(05/27) 1–19.
Ptolemy's table of chord lengths from the Almagest converted into decimal values and recalculated. Presentation and discussion of Ptolemy's method of calculation and sexagesimal values in comparison to calculations by trigonometric functions with regard to several editors. A significant relationship between the difference values of the two methods and angle num-ber was found: The higher the expansion angle, the greater the overestimation of chord lengths. Implications for early scientific astronomy in context with the development of mathematical methodology are discussed.
Integer partitions detect the primes. Craig, William; van Ittersum, Jan-Willem; Ono, Ken (2024). 121(39) e2409417121-.
Integer partitions arise naturally in additive number theory, algebraic geometry, combinatorics, mathematical physics, and representation theory. We have identified a surprising role for partitions in multiplicative number theory. The prime numbers, the building blocks of multiplicative number theory, are the solutions of infinitely many special ?Diophantine equations? in well-studied partition functions. In other words, integer partitions detect the primes in infinitely many natural ways. We show that integer partitions, the fundamental building blocks in additive number theory, detect prime numbers in an unexpected way. Answering a question of Schneider, we show that the primes are the solutions to special equations in partition functions. For example, an integer n ≥ 2 is prime if and only if (3n3?13n2+18n?8)M1(n)+(12n2?120n+212)M2(n)?960M3(n)=0, where the Ma(n) are MacMahon?s well-studied partition functions. More generally, for MacMahonesque partition functions Ma?(n), we prove that there are infinitely many such prime detecting equations with constant coefficients, such as 80M(1,1,1)(n)?12M(2,0,1)(n)+12M(2,1,0)(n)+??12M(1,3)(n)?39M(3,1)(n)=0.
Understanding the Radial Acceleration Relation of Dwarf Galaxies with Emergent Gravity. Sanghyeon, Han; Seong, Hwang Ho; Youngsub, Yoon (2024). 57(2) 249–259.
We examine whether the radial acceleration relation (RAR) of dwarf galaxies can be explained by Verlinde's emergent gravity. This is the extension of Yoon et al. (2023), which examine the RAR of typical spiral galaxies, to less massive systems. To do this, we compile the line-of-sight velocity dispersion profiles of 30 dwarf galaxies in the Local Group from the literature. We then calculate the expected gravitational acceleration from the stellar component in the framework of the emergent gravity, and compare it with that from observations. The calculated acceleration with the emergent gravity under the assumption of a quasi-de Sitter universe agrees with the observed one within the uncertainty. Our results suggest that the emergent gravity can explain the kinematics of galaxies without introducing dark matter, even for less massive galaxies where dark matter is expected to dominate. This sharply contrasts with MOND, where a new interpolating function has to be introduced for dwarf galaxies to explain their kinematics without dark matter.
How Meteor Showers Can Guide the Search for Long Period Comets. Hemmelgarn, Samantha; Moskovitz, Nicholas; Pilorz, Stuart; Jenniskens, Peter (2024).
With orbital periods longer than 200 years, most long-period comets (LPCs) remain undiscovered until they are in-bound towards perihelion. The comets that pass close to Earth's orbit are Potentially Hazardous Objects (PHOs). Those with orbital periods up to ~4000 years tend to have passed close to Earth's orbit in a previous orbit and produced a meteoroid stream dense enough to be detected at Earth as a meteor shower. In anticipation of Rubin Observatory's Legacy Survey of Space and Time (LSST), we investigate how these meteor showers can guide dedicated searches for their parent comets. Assuming search parameters informed by LSST, we calculated where the 17 known parent bodies of long-period comet meteor showers would have been discovered based on a cloud of synthetic comets generated from the shower properties as measured at Earth. We find that the synthetic comets predict the on-sky location of the parent comets at the time of their discovery. The parent comet's location on average would have been 1.51 ±1.19° from a line fit through the synthetic comet cloud. The difference between the heliocentric distance of the parent and mean heliocentric distance of synthetic comets on the line was 2.09 ±1.89 au for comets with unknown absolute nuclear magnitudes and 0.96 ±0.80 au for comets with known absolute nuclear magnitudes. We applied this method to the σ-Hydrids, the proposed meteor shower of Comet Nishimura, and found that it successfully matched the pre-covery location of this comet 8 months prior to Nishimura's discovery.

“hubbel”: A Hybrid Letterbox That Stimulates Civic Participation Through Local Information Sharing in Neighbourhoods. Maas, Franzisca; Wolf, Sara; Weber, Michael; Fiedler, Marie Luisa; Zottmann, Nils; Lester, Marlene; Hohm, Jonathan; Sessler, Luise; Schmitt, Katja Patricia; Balser, Andreas; Heinisch, Melina Joline; Hofmann, Tabea Carolina; Maier, Simon; Ölschläger, Amanda; Popp, Alisa; Hurtienne, Jörn in DIS ’23 (2023). 1826–1841.
Local civic participation is essential to democracy. Yet, citizens need to be informed about local matters to get involved. Becoming and staying informed about developments in one’s neighbourhood is difficult as local knowledge is scattered among online and offline sources, hard to find and understand. Using participatory Contextual Design we curated a novel form of participation with the interactive artifact "hubbel", which combines the digital and the analogue through a hybrid letterbox to crowd-source local knowledge. During our two-month in-the-wild evaluation, the hubbel was heavily used (260 postcards, 2067 visits). It stimulated democratic discourse and (offline) political participation by rendering tacit local issues visible. We propose ways to improve the hubbel’s design so that citizens can more easily share their expertise with others and to avoid harmful consequences like pseudo-participation. Finally, the hubbel demonstrates why analogue components are indispensable for civic participation tools. Supplements and open-source code: OSF-Link [https://osf.io/jcgue/].
Motivations underlying self-infliction of pain during thinking for pleasure. Eder, Andreas B.; Maas, Franzisca; Schubmann, Alexander; Krishna, Anand; Erle, Thorsten M. (2022). 12(1) 11247.
Previous research suggested that people prefer to administer unpleasant electric shocks to themselves rather than being left alone with their thoughts because engagement in thinking is an unpleasant activity. The present research examined this negative reinforcement hypothesis by giving participants a choice of distracting themselves with the generation of electric shock causing no to intense pain. Four experiments (N\thinspace=\thinspace254) replicated the result that a large proportion of participants opted to administer painful shocks to themselves during the thinking period. However, they administered strong electric shocks to themselves even when an innocuous response option generating no or a mild shock was available. Furthermore, participants inflicted pain to themselves when they were assisted in the generation of pleasant thoughts during the waiting period, with no difference between pleasant versus unpleasant thought conditions. Overall, these results question that the primary motivation for the self-administration of painful shocks is avoidance of thinking. Instead, it seems that the self-infliction of pain was attractive for many participants, because they were curious about the shocks, their intensities, and the effects they would have on them.

Citizen Needs – To Be Considered: Requirements for Local Civic Participation Tools. Maas, Franzisca; Wolf, Sara; Hohm, Anna; Hurtienne, Jörn (2021). 20(2) 141–159.
In this paper, we argue for and present an empirical study of putting citizens into focus during the early stages of designing tools for civic participation in a midsized German town. Drawing on Contextual and Participatory Design, we involved 105 participants by conducting interviews, using Photovoice and participating in a local neighbourhood meeting. Together with citizens, we built an Affinity Diagram, consolidated the data and identified key insights. As a result, we present and discuss different participation identities such as Motivated Activists, Convenience Participants or Companions and a collection of citizen needs for local civic participation, e. g., personal contact is irreplaceable for motivation, trust and mutual understanding, and some citizens preferred to “stumble across” information rather than actively searching for it. We use existing participation tools to demonstrate how individual needs could be addressed. Finally, we apply our insights to an example in our local context. We conclude that if we want to build digital tools that go beyond tokenistic, top-down ways of civic participation and that treat citizens as one homogeneous group, citizens need to be part of the design process right from the start.

Move&Find: The Value of Kinaesthetic Experience in a Casual Data Representation. Hurtienne, Jörn; Maas, Franzisca; Carolus, Astrid; Reinhardt, Daniel; Baur, Cordula; Wienrich, Carolin (2020). 40(6) 61–75.
The value of a data representation is traditionally judged based on aspects like effectiveness and efficiency that are important in utilitarian or work-related contexts. Most multisensory data representations, however, are employed in casual contexts where creativity, affective, physical, intellectual, and social engagement might be of greater value. We introduce Move&Find, a multisensory data representation in which people pedalled on a bicycle to exert the energy required to power a search query on Google's servers. To evaluate Move&Find, we operationalized a framework suitable to evaluate the value of data representations in casual contexts and experimentally compared Move&Find to a corresponding visualization. With Move&Find, participants achieved a higher understanding of the data. Move&Find was judged to be more creative and encouraged more physical and social engagement—components of value that would have been missed using more traditional evaluation frameworks.
Landauer Principle and General Relativity. Herrera, Luis (2020). 22(3)
We endeavour to illustrate the physical relevance of the Landauer principle applying it to different important issues concerning the theory of gravitation. We shall first analyze, in the context of general relativity, the consequences derived from the fact, implied by Landauer principle, that information has mass. Next, we shall analyze the role played by the Landauer principle in order to understand why different congruences of observers provide very different physical descriptions of the same space-time. Finally, we shall apply the Landauer principle to the problem of gravitational radiation. We shall see that the fact that gravitational radiation is an irreversible process entailing dissipation, is a straightforward consequence of the Landauer principle and of the fact that gravitational radiation conveys information. An expression measuring the part of radiated energy that corresponds to the radiated information and an expression defining the total number of bits erased in that process, shall be obtained, as well as an explicit expression linking the latter to the Bondi news function.
Perspectives on Data Reproducibility and Replicability in Paleoclimate and Climate Science. Bush, Rosemary; Dutton, Andrea; Evans, Michael; Loft, Rich; Schmidt, Gavin A. (2020). 2(4)
Are Results in Geomorphology Reproducible?. Church, M.; Dudill, A.; Venditti, J. G.; Frey, P. (2020). 125(8) e2020JF005553.
Abstract There recently has arisen substantial concern for the reproducibility of scientific findings, but the discussion has not significantly impacted Earth science. We consider repetition, replication, and reproducibility in Earth science, using an example from geomorphology. Repetition repeats the program of observations in the same exercise to establish precision of results. Replication is duplication of observations using similar resources but in an independent program. Reproduction is confirmation of scientific principles using different resources in an independent program. We conclude that results will mainly be limited to reproduction—confirmation of principles—and that this is the essential goal for advancing the science. We illustrate these concepts by review of our experiments on the infiltration of fine grains in flowing water into a bed of coarser grains, conducted using glass beads in a laboratory flume.

Toward Reproducible Environmental Modeling for Decision Support: A Worked Example. White, Jeremy T.; Foster, Linzy K.; Fienen, Michael N.; Knowling, Matthew J.; Hemmings, Brioch; Winterle, James R. (2020). Volume 8 - 2020
A fully worked example of decision-support-scale uncertainty quantification (UQ) and parameter estimation (PE) is presented. The analyses are implemented for an existing groundwater flow model of the Edwards aquifer, Texas, USA, and are completed in a script-based workflow that strives to be transparent and reproducible. High-dimensional PE is used to history-match simulated outputs to corresponding state observations of spring flow and groundwater level. Then a hindcast of a historical drought is made. Using available state observations recorded during drought conditions, the combined UQ and PE analyses are shown to yield an ensemble of model results that bracket the observed hydrologic responses. All files and scripts used for the analyses are placed in the public domain to serve as a template for other practitioners who are interested in undertaking these types of analyses.
Degradation of polyethylene glycols and polypropylene glycols in microcosms simulating a spill of produced water in shallow groundwater. Rogers, Jessica D.; Thurman, E. Michael; Ferrer, Imma; Rosenblum, James S.; Evans, Morgan V.; Mouser, Paula J.; Ryan, Joseph N. (2019). 21(2) 256–268.
Polyethylene glycols (PEGs) and polypropylene glycols (PPGs) are frequently used in hydraulic fracturing fluids and have been detected in water returning to the surface from hydraulically fractured oil and gas wells in multiple basins. We identified degradation pathways and kinetics for PEGs and PPGs under conditions simulating a spill of produced water to shallow groundwater. Sediment-groundwater microcosm experiments were conducted using four produced water samples from two Denver-Julesburg Basin wells at early and late production. High-resolution mass spectrometry was used to identify the formation of mono- and di-carboxylated PEGs and mono-carboxylated PPGs, which are products of PEG and PPG biodegradation, respectively. Under oxic conditions, first-order half-lives were more rapid for PEGs (<0.4–1.1 d) compared to PPGs (2.5–14 d). PEG and PPG degradation corresponded to increased relative abundance of primary alcohol dehydrogenase genes predicted from metagenome analysis of the 16S rRNA gene. Further degradation was not observed under anoxic conditions. Our results provide insight into the differences between the degradation rates and pathways of PEGs and PPGs, which may be utilized to better characterize shallow groundwater contamination following a release of produced water.

Gravitational Starlight Deflection Measurements during the 21 August 2017 Total Solar Eclipse. Bruns, Donald G. (2018).
Precise starlight positions near the sun were measured during the 21 August 2017 total solar eclipse in order to measure their gravitational deflections. The equipment, procedures, and analysis are described in detail. A portable refractor, a CCD camera, and a computerized mount were set up in Wyoming. Detailed calibrations were necessary to improve accuracy and precision. Nighttime measurements taken just before the eclipse provided cubic optical distortion corrections. Calibrations based on star field images 7.4 deg on both sides of the sun taken during totality gave linear and quadratic plate constants. A total of 45 images of the sky surrounding the Sun were acquired during the middle part of totality, with an integrated exposure of 22 seconds. The deflection analysis depended on accurate star positions from the USNO's UCAC5 star catalog. The final result was a deflection coefficient L = 1.752 arcsec, compared to the theoretical value of L = 1.751 arcsec, with an uncertainty of only 3%.
Identification of polypropylene glycols and polyethylene glycol carboxylates in flowback and produced water from hydraulic fracturing. Thurman, E. Michael; Ferrer, Imma; Rosenblum, James; Linden, Karl; Ryan, Joseph N. (2017). 323 11–17.
The purpose of the study was to separate and identify the unknown surfactants present in flowback and produced water from oil and gas wells in the Denver-Julesburg Basin (Niobrara Formation) in Weld County, Colorado, USA. Weld County has been drilled extensively during the last five years for oil and gas between 7000–8000 feet below land-surface. Polypropylene glycols (PPGs) and polyethylene glycols carboxylates (PEG-Cs) were found for the first time in these flowback and produced water samples. These ethoxylated surfactants may be used as friction reducers, clay stabilizers, and surfactants. Ultrahigh-performance liquid chromatography/quadrupole-time-of-flight mass spectrometry (UHPLC/QTOF-MS) was used to separate and identify the different classes of PPGs, PEG-Cs, and their isomers. The Kendrick mass scale was applied along with mass spectrometry/mass spectrometry (MS-MS) with accurate mass for rapid and unequivocal identification. The PPGs and their isomers occur at the ppm concentration range and may be useful as “fingerprints” of hydraulic-fracturing. Comparing these detections to the compounds used in the fracturing process from FracFocus 3.0 (https://fracfocus.org), it appears that both PPGs and polyethylene glycols (PEGs) are commonly named as additives, but the PEG-Cs have not been reported. The PEG-Cs may be trace impurities or degradation products of PEGs.

Most computational hydrology is not reproducible, so is it really science?. Hutton, Christopher; Wagener, Thorsten; Freer, Jim; Han, Dawei; Duffy, Chris; Arheimer, Berit (2016). 52(10) 7548–7555.
Abstract Reproducibility is a foundational principle in scientific research. Yet in computational hydrology the code and data that actually produces published results are not regularly made available, inhibiting the ability of the community to reproduce and verify previous findings. In order to overcome this problem we recommend that reuseable code and formal workflows, which unambiguously reproduce published scientific results, are made available for the community alongside data, so that we can verify previous findings, and build directly from previous work. In cases where reproducing large-scale hydrologic studies is computationally very expensive and time-consuming, new processes are required to ensure scientific rigor. Such changes will strongly improve the transparency of hydrological research, and thus provide a more credible foundation for scientific advancement and policy support.

Toward the Geoscience Paper of the Future: Best practices for documenting and sharing research from data to software to provenance. Gil, Yolanda; David, Cédric H.; Demir, Ibrahim; Essawy, Bakinam T.; Fulweiler, Robinson W.; Goodall, Jonathan L.; Karlstrom, Leif; Lee, Huikyo; Mills, Heath J.; Oh, Ji-Hyun; Pierce, Suzanne A.; Pope, Allen; Tzeng, Mimi W.; Villamizar, Sandra R.; Yu, Xuan (2016). 3(10) 388–415.
Abstract Geoscientists now live in a world rich with digital data and methods, and their computational research cannot be fully captured in traditional publications. The Geoscience Paper of the Future (GPF) presents an approach to fully document, share, and cite all their research products including data, software, and computational provenance. This article proposes best practices for GPF authors to make data, software, and methods openly accessible, citable, and well documented. The publication of digital objects empowers scientists to manage their research products as valuable scientific assets in an open and transparent way that enables broader access by other scientists, students, decision makers, and the public. Improving documentation and dissemination of research will accelerate the pace of scientific discovery by improving the ability of others to build upon published work.
A note on the Landauer principle in quantum statistical mechanics. Jakšić, Vojkan; Pillet, Claude-Alain (2014). 55(7) 075210.
The Landauer principle asserts that the energy cost of erasure of one bit of information by the action of a thermal reservoir in equilibrium at temperature T is never less than kBT log 2. We discuss Landauer's principle for quantum statistical models describing a finite level quantum system coupled to an infinitely extended thermal reservoir . Using Araki's perturbation theory of KMS states and the Avron-Elgart adiabatic theorem we prove, under a natural ergodicity assumption on the joint system , that Landauer's bound saturates for adiabatically switched interactions. The recent work [Reeb, D. and Wolf M. M., “(Im-)proving Landauer's principle,” preprint arXiv:1306.4352v2 (2013)] on the subject is discussed and compared.

The interfacial conformation of polypropylene glycols and their foam properties. Tan, Su Nee; Fornasiero, Daniel; Sedev, Rossen; Ralston, John (2006). 19(6) 703–712.
The foam behaviour of low molecular weight polypropylene glycols (PPG) was investigated as a function of concentration and molecular weight (190–2000gmol−1). For each polypropylene glycol, foam stability increases with concentration and passes through a maximum, beyond which foamability is suppressed as the solubility limit of the glycol is exceeded and droplets of glycol form. Light scattering data as well as static and dynamic surface tension results provide the key information leading to these interpretations. A maximum in foamability was observed for the PPG molecules with increasing molecular weight (caused by a change in molecular conformation at the interface). This suppresses the Marangoni effect and leads to a decrease in foam stability.
Call-by-push-value: Decomposing call-by-value and call-by-name. Levy, Paul Blain (2006). 19(4) 377–414.
We present the call-by-push-value (CBPV) calculus, which decomposes the typed call-by-value (CBV) and typed call-by-name (CBN) paradigms into fine-grain primitives. On the operational side, we give big-step semantics and a stack machine for CBPV, which leads to a straightforward push/pop reading of CBPV programs. On the denotational side, we model CBPV using cpos and, more generally, using algebras for a strong monad. For storage, we present an O'Hearn-style "behaviour semantics'' that does not use a monad.We present the translations from CBN and CBV to CBPV. All these translations straightforwardly preserve denotational semantics. We also study their operational properties: simulation and full abstraction.We give an equational theory for CBPV, and show it equivalent to a categorical semantics using monads and algebras. We use this theory to formally compare CBPV to Filinski's variant of the monadic metalanguage, as well as to Marz's language SFPL, both of which have essentially the same type structure as CBPV. We also discuss less formally the differences between the CBPV and monadic frameworks.

The Holevo bound and Landauer’s principle. Plenio, Martin B (1999).
Landauer's principle states that the erasure of information generates a corresponding amount of entropy in the environment. We show that Landauer's principle provides an intuitive basis for Holevo bound on the classical capacity of a quantum channel.
