• Fall Advances in the Timing of Molt in Birds in the Southwestern United States. Kittelberger, Kyle D.; Neate-Clegg, Montague H. C.; cSekerciouglu, cCaugan Hakki (2026). 000–000.

  AbstractMolt is a critical event in the annual cycle of birds. Although we know an increasing amount about the impacts of climate change on the timing of other avian events, there has been relatively limited work conducted on changes in molt phenology over time. In this study, we utilized a 13-year bird-banding dataset from southeastern Utah to examine long-term trends in the molt timing of body and flight feathers during both the spring and the fall migratory seasons, accounting for temporal trends in nonmolting birds and how trends may vary between different sexes and ages of birds. We found that there were no significant temporal trends in molt timing in the spring but there were significant trends in the fall, such that birds were advancing the timing of their body and flight feather molt over time. Finally, we highlight the significant influence of climate on molt phenology: El Niño/Southern Oscillation and maximum temperature were both associated with advances in spring body molt, maximum temperature was associated with delays in fall flight feather molt timing, and precipitation was associated with advances in both fall body and flight feather molt timing. This study provides the first examination of long-term trends in the molt phenology of North American birds, showing that over the past decade, birds in the western United States have advanced their feather molt timing in the fall at a rate of roughly one day/year.
• A Framework for Securing Personal Data Shared by Users on the Digital Platforms. Anjum, Nirjhor N. Meghanathan (ed.) (2025). (Vol. 17) 1–22.

  Public disclosure of private data such as mobile phone numbers, dates of birth, identity card information, and financial data on social websites represents a significant threat to cybersecurity. Both external and internal intrusions infringe on users' privacy, and the available security practices are not preventing unauthorized access. Substandard encryption, poor access controls, and weak policy enforcement form the core deficiencies of handling private data in this study. An in-depth analysis, comprising industry surveys, interviews with experts, and case studies of eCommerce and digital service companies, is carried out to assess the prevailing practices and their shortcomings. It is seen that most of the companies do not have adequate policies and technical measures, and user data is extremely susceptible to misuse. To fill this gap, a Citizen Digital Identity Portal (CDIP) is envisioned as an eGovernance project sponsored by the government. This solution combines encryption, access controls, and API-based identity confirmation to enable companies to confirm user identities without revealing or holding personal information. The threat of abuse by both internal and external entities is therefore greatly minimized. The study concludes that companies cannot guarantee data security alone and that a policy-driven centralized model must be in place. The CDIP model helps bridge the gap between technology and cybersecurity rules. It offers a flexible and powerful way to protect personal information in today’s digital world.

• Evaluating the Response of the Labrador Sea to Greenland Meltwater Influx With High-Resolution Eddy-Rich NEMO Simulations. Hoshyar, P.; Pennelly, C.; Myers, P. G. (2025). 130(5) e2024JC022102.

  Abstract The Greenland Ice Sheet has undergone substantial mass loss in recent decades primarily due to oceanic and atmospheric warming, contributing to global sea-level rise and enhanced ocean stratification. This study examines the Labrador Sea's response to increased Greenland freshwater influx using a very high-resolution, eddy-rich configuration of the NEMO ocean model. Two 9-year long experiments with identical setups, except one excluding Greenland runoff, suggest that freshwater influx leads to freshwater content increase (by up to 39\%) and intensified stratification (enhanced convective resistance by up to 29\%) in the Labrador Sea, whereas heat content remains mainly unchanged (up to 6\% increase). Strengthened stratification weakens but does not entirely stop deep convection allowing continued water mass formation within the region (maximum mixed layer depth differences of up to 635 m). A sensitivity analysis indicates warmer, saltier surface waters and colder, fresher subsurface layers when Greenland meltwater is excluded likely driven by reduced lateral exchange from the West Greenland Current system and enhanced southward Arctic Water transport across Davis Strait. Offshore freshwater exchange in the Labrador Sea interior is not solely controlled by Greenland meltwater influx but also by air-sea fluxes and deepwater formation. Over longer timescales exceeding a decade, ongoing freshening and intensified stratification could further disrupt essential oceanic processes with potential consequences for deepwater formation and Atlantic Meridional Overturning Circulation. These findings underscore the importance of accurately representing Greenland meltwater and shelf-basin exchanges in models to improve the predictions of Labrador Sea under future warming.
• Weakened Atlantic Meridional Overturning Circulation causes the historical North Atlantic Warming Hole. Li, Kai-Yuan; Liu, Wei (2025). 6(1) 416.

  Most oceans over the globe have experienced surface warming during the past century, but the subpolar Atlantic is quite otherwise. The sea surface temperature cooling trend to the south of Greenland, known as the North Atlantic Warming Hole, has raised debate over whether it is driven by the slowing of the Atlantic Meridional Overturning Circulation. Here we use observations as a benchmark and climate models as a tool to demonstrate that only models simulating a weakened historical Atlantic overturning can broadly reproduce the observed cooling and freshening in the warming hole region. This, in turn, indicates that the realistic Atlantic overturning slowed between 1900 and 2005, at a rate of −1.01 to −2.97thinspaceSv century−1 (1\thinspaceSv\thinspace=\thinspace106\thinspacem3\thinspaces−1), according to a sea-surface-temperature-based fingerprint index estimate. Particularly, the Atlantic overturning slowdown causes an oceanic heat transport divergence across the subpolar North Atlantic, which, while partially offset by enhanced ocean heat uptake, results in cooling over the warming hole region.

• RLFuzz: Accelerating Hardware Fuzzing with Deep Reinforcement Learning. Götz, Raphael; Sendner, Christoph; Ruck, Nico; Rostami, Mohamadreza; Dmitrienko, Alexandra; Sadeghi, Ahmad-Reza (2025).

  Once hardware is manufactured, it becomes immutable, and any design flaws or vulnerabilities are permanent. Therefore, comprehensive testing of hardware designs is essential before production. However, the increasing complexity of modern processors makes static analysis and formal verification increasingly challenging. Fuzzing is a highly effective technique for detecting software vulnerabilities but adapting it to hardware presents unique challenges due to the fundamental differences between software and hardware. However, the current state-of-the-art in hardware fuzzing still has significant limitations, particularly in terms of performance, practicality, and the need for human intervention. To address these issues, we introduce RLFuzz, a novel hardware fuzzer that employs reinforcement learning to explore processors autonomously, achieving faster and more comprehensive coverage. Reinforcement learning enables the fuzzer to learn from its interactions with the processor without requiring labeled data, allowing it to more effectively select modifications for test cases and target previously unexplored areas. RLFuzz uses an asynchronous training mechanism that permits concurrent fuzzing and neural network training. To optimize RLFuzz, we performed an extensive evaluation of various deep Q-learning optimization techniques and hyper-parameters. We then tested the optimized fuzzer on three complex RISC-V cores-the Rocket core, CVA6, and BOOM-and compared its performance to a current hardware fuzzer, TheHuzz [20]. Our results show that RLFuzz achieved up to 1.77% higher coverage, and on average 2.35 times faster, and demonstrated a maximum speedup of up to 6.93 times. For branch coverage, the average speedup was 7.85 times, with a peak speedup of 92.98 times. Additionally, RLFuzz needed less time to complete 100,000 test cases and did not require any human intervention.

• A weakened Atlantic Meridional Overturning Circulation will affect future heat waves by mostly attenuating their severity. Duarte, David; Liu, Wei; Zhang, Liping (2025). 63(6) 238.

  Atmospheric heat waves are expected to be more severe, frequent and persistent in the decades to come. Here, we sought to ascertain to what extent such a worsened scenario of this adverse phenomenon may be affected by a projected slowdown of the Atlantic Meridional Overturning Circulation (AMOC), thus accounting for an important gap in our knowledge of physical mechanisms related to heat waves -- the role of large-scale climate variability pertaining to ocean circulation impacts. We conducted a comparison between two CCSM4 simulations (nominal forcings vs. a parallel sensitivity experiment that keeps the AMOC strength constant). Our findings reveal that a hampered northward heat transport due to the AMOC weakening causes robust, widespread and significant cooling in the Northern Hemisphere and parts of South America relative to the control simulation, whereas most of the Southern Hemisphere displays a warming signal, but in a much milder amplitude and typically lacking significance over land masses. Therefore, notwithstanding other potentially noxious effects of an abated AMOC on the climate system, it should act mostly as an attenuating factor in this regard, as future heat waves will generally not be as intense as they could be under a global warming scenario where the AMOC would keep its strength.
• Period-doubling in the phase dynamics of a shunted HgTe quantum well Josephson junction. Liu, Wei; Piatrusha, Stanislau U.; Liang, Xianhu; Upadhyay, Sandeep; Fürst, Lena; Gould, Charles; Kleinlein, Johannes; Buhmann, Hartmut; Stehno, Martin P.; Molenkamp, Laurens W. (2025). 16(1) 3068.

  The fractional AC Josephson effect is a discerning property of topological superconductivity in hybrid Josephson junctions. Recent experimental observations of missing odd Shapiro steps and half Josephson frequency emission in various materials have sparked significant debate regarding their potential origin in the effect. In this study, we present microwave emission measurements on a resistively shunted Josephson junction based on a HgTe quantum well. We demonstrate that, with significant spurious inductance in the shunt wiring, the experiment operates in a nonlinear dynamic regime characterized by period-doubling. This leads to additional microwave emission peaks at half of the Josephson frequency, fJ/2, which can mimic the 4\($\pi$\)-periodicity of topological Andreev states. The observed current-voltage characteristics and emission spectra are well-described by a simple RCLSJ model. Furthermore, we show that the nonlinear dynamics of the junction can be controlled using gate voltage, magnetic field, and temperature, with our model accurately reproducing these effects without incorporating any topological attributes. Our observations urge caution in interpreting emission at fJ/2 as evidence for gapless Andreev bound states in topological junctions and suggest the appropriate parameter range for future experiments.

  Modern 3-D printing techniques enable the rapid prototyping of complex mechanical structures. We leverage this capability to create customizable pressure sensors by combining soft and ferromagnetic filaments during the printing process. The resulting inductive sensors utilize a lattice structure based on a body-centered cubic unit cell, exhibiting tunable stiffness with Young's moduli ranging from 112 to 368 kPa and sensitivities between \($-$\)0.17 and \($-$\)0.11% kPa\($^-1$\). The sensors show minimal hysteresis and remain stable throughout 10 000 compression cycles. The versatility of this approach is further demonstrated through the fabrication of a fully printed inductive joystick.

• The Power of Reading Support for Learners: A State-of-the-Art Analysis of Computer-Assisted Reading from an Information Systems Perspective. Haenel, M.; Wambsganss, T.; Söllner, M. (2024).

  Reading and synthesizing scientific papers is a crucial skill for students. However, many students in higher education struggle to effectively comprehend scientific texts. To address this challenge, research has leveraged computer-assisted reading (CAR) systems to improve students' reading comprehension abilities at scale. However, the research and application of CAR in higher education still lack an organized overview and clear terminology due to the multidisciplinary character of the research field (e.g., Education didactic, Human-Computer Interaction, or Information Systems). Therefore, we perform a systematic literature review on CAR from an interdisciplinary Information Systems perspective. We take the socio-technical systems theory as a lens to organize, summarize past literature as well to identify white spots for a future research agenda. The main contributions of this paper are the synthesis and consolidation of CAR to create a basis for all researchers investigating the research field of CAR in higher education.

• GNN-Based Code Annotation Logic for Establishing Security Boundaries in C Code. Gadey, Varun; Goetz, Raphael; Sendner, Christoph; Sovio, Sampo; Dmitrienko, Alexandra (2024).

  Securing sensitive operations in today's interconnected software landscape is crucial yet challenging. Modern platforms rely on Trusted Execution Environments (TEEs), such as Intel SGX and ARM TrustZone, to isolate security sensitive code from the main system, reducing the Trusted Computing Base (TCB) and providing stronger assurances. However, identifying which code should reside in TEEs is complex and requires specialized expertise, which is not supported by current automated tools. Existing solutions often migrate entire applications to TEEs, leading to suboptimal use and an increased TCB. To address this gap, we propose Code Annotation Logic (CAL), a pioneering tool that automatically identifies security sensitive components for TEE isolation. CAL analyzes codebases, leveraging a graph-based approach with novel feature construction and employing a custom graph neural network model to accurately determine which parts of the code should be isolated. CAL effectively optimizes TCB, reducing the burden of manual analysis and enhancing overall security. Our contributions include the definition of security sensitive code, the construction and labeling of a comprehensive dataset of source files, a feature rich graph based data preparation pipeline, and the CAL model for TEE integration. Evaluation results demonstrate CAL's efficacy in identifying sensitive code with a recall of 86.05%, an F1 score of 81.56%, and an identification rate of 91.59% for security sensitive functions. By enabling efficient code isolation, CAL advances the secure development of applications using TEEs, offering a practical solution for developers to reduce attack vectors.

  Diffusion models have been successfully used in various applications such as text-to-image generation, 3D assets generation, controllable image editing, video generation, natural language generation, audio synthesis, and motion generation. The rate of progress on diffusion models is astonishing. In the year 2022 alone, diffusion models have been applied to many large-scale text-to-image foundation models, such as DALL-E 2 [Ramesh et al. 2022], Imagen [Saharia et al. 2022], Stable Diffusion [Rombach et al. 2022], and eDiff-I [Balaji et al. 2022]; video generation models such as Imagen Video [Ho et al. 2022] and Make-a-video [Singer et al. 2022]; 3D asset generation models such as Magic3D [Lin et al. 2022] and DreamFusion [Poole et al. 2022]. This course covers the advances in diffusion models over the last few years and will be tailored to the computer graphics community. We will first cover the fundamental machine learning and deep learning techniques relevant to diffusion models. Next, we will present state-of-the-art techniques for the application of diffusion models to high-fidelity image synthesis, controllable image generation, compositional representation learning, and 3D asset generation. Finally, we will conclude with a discussion on the future application of this technology, societal impact and open research problems. After the course, the attendees will learn basic knowledge about diffusion models and how such models can be applied to different applications such as image generation, image editing, and 3D asset generation.

  Mutig, entschlossen und mit beispiellosem Einsatz kämpfte Simon Weil zeit ihres Lebens für eine bessere Welt. Dabei stellte sie die leidvolle Erfahrung der Fabrikarbeiter und -arbeiterinnen in den Mittelpunkt ihres Engagements. Überraschenderweise steht Weils Vision zur Lösung der sozialen Frage in engem Verhältnis zu Gott. Dabei geht es ihr aber keinesfalls um ein Aufgeben des Weltlichen im Glauben. Die Ordensschwester Britta Müller-Schauenburg beschreibt Weils Haltung in ihrem Vorwort vielmehr als einen "geistlichen Umgang" mit "geistlosen Routinen": Fremdbestimmtheit und Sinnlosigkeitsempfindungen, die sich wie die soziale Ungerechtigkeit bis heute weiter ausbreiten. Weils Texte, die jetzt endlich auf Deutsch vorliegen, legen davon ein eindrucksvolles Zeugnis ab.

• Engaging Learners in Online Video Lectures with Dynamically Scaffolding Conversational Agents. Winkler, Rainer; Hobert, Sebastian; Fischer, Tizian; Salovaara, Antti; Söllner, Matthias; Leimeister, Jan Marco (2020).

  Online education creates new opportunities for learners, which has led to sharply increasing enrollment in the last few years. Despite these benefits, past research shows that the lack of individual interaction with educators creates low learner engagement that leads to high attrition rates, which remains a major challenge in the field. Dynamically scaffolding conversational agents built into online video lectures promise to address this problem by individually interacting with learners, similar to educators’ scaffolding behavior. These agents are equipped with recent natural language processing capabilities, creating human-like conversations that help learners to be more engaged in the learning process. To test our hypothesis, we built a dynamically scaffolding conversational agent named Sara and compared it with an often-implemented static conversational agent built into two online video lectures. We deployed a lab experiment with 182 learners. The neurophysiological measurements revealed that Sara significantly improved learner engagement partly explained by differences in learners’ perceptions in the way they experienced the interaction. This study connects to already existing conversational agent studies in online education and highlights the importance of including dynamically scaffolding conversational agents in online video lectures to address the problem of low learner engagement in online education.

• Designing a Conversational Agent as a Formative Course Evaluation Tool. Wambsganss, Thiemo; Winkler, Rainer; Schmid, Pascale; Söllner, Matthias N. Gronau, M. Heine, H. Krasnova, K. Poustcchi (eds.) (2020). 1234–1249.

  Today's graduating students face ever-changing environments when they enter their job life. Educational institutions must therefore continuously develop their course structure and content in order to prepare their students to be future employees. A very important means for developing the courses is the students' course evaluations. Due to financial and organizational restrictions, these course evaluations are usually carried out quantitatively and at the end of the semester. However, past research has shown that this kind of evaluation faces certain constraints such as low acceptance rates, only time-related insights and low-quality answers that do not really help the lecturer to improve the course. Drawing on social response theory, we propose that conversational agents as a formative course evaluation tool are able to address the mentioned problems by interactively engaging with students. Therefore, we propose a set of design principles and evaluate them with our prototype Eva.

• Hybrid Encryption Algorithms for Medical Data Storage Security in Cloud Database. Zhang, Fenghua (2019). (Vol. 11) 57–73.

  Cloud database are derivatives of Cloud computing. At present, most medical institutions store data in cloud database. Although the cloud database improves the efficiency of use, it also poses a huge impact and challenge to the secure storage of data. The article proposes a hybrid algorithm to solve the data security problem in the hospital cloud database. First, the AES algorithm is improved. The improved algorithm is called P-AES algorithm. The P-AES algorithm is then combined with the RSA algorithm, called a hybrid algorithm. The experimental results show that the hybrid encryption algorithm has the advantages of fast encryption and decryption speed, high security, good processing ability for longer data, and can solve the data security problem in cloud database to a certain extent. The algorithm has been successfully applied to hospital information management system.

• A caveat on the Savage–Dickey density ratio: The case of computing Bayes factors for regression parameters. Heck, Daniel W. (2019). 72(2) 316–333.

  The Savage?Dickey density ratio is a simple method for computing the Bayes factor for an equality constraint on one or more parameters of a statistical model. In regression analysis, this includes the important scenario of testing whether one or more of the covariates have an effect on the dependent variable. However, the Savage?Dickey ratio only provides the correct Bayes factor if the prior distribution of the nuisance parameters under the nested model is identical to the conditional prior under the full model given the equality constraint. This condition is violated for multiple regression models with a Jeffreys?Zellner?Siow prior, which is often used as a default prior in psychology. Besides linear regression models, the limitation of the Savage?Dickey ratio is especially relevant when analytical solutions for the Bayes factor are not available. This is the case for generalized linear models, non-linear models, or cognitive process models with regression extensions. As a remedy, the correct Bayes factor can be computed using a generalized version of the Savage?Dickey density ratio.

  A core aspect of science is using data to assess the degree to which data provide evidence for competing claims, hypotheses, or theories. Evidence is by definition something that should change the credibility of a claim in a reasonable person’s mind. However, common statistics, such as significance testing and confidence intervals have no interface with concepts of belief, and thus it is unclear how they relate to statistical evidence. We explore the concept of statistical evidence, and how it can be quantified using the Bayes factor. We also discuss the philosophical issues inherent in the use of the Bayes factor.

  We describe a corpus of naturally occurring road ice weather forecasts and the associated weather prediction data they are based upon. We also show how observations from an analysis of this corpus have been applied to build a prototype Natural Language Generation (NLG) system for producing road ice forecasts. While this corpus occurs in a narrow domain, it has much wider applicability due to the nature of its spatial descriptions, whose primary communicative goal is to describe the interaction between meteorological parameters and geographic features.
• The effects of insoluble surfactants on the linear stability of a core-annular flow. Wei, Hsien-Hung; Rumschitzki, David S. (2005). 541 115–142.

  The effects of an insoluble surfactant on the linear stability of a two-fluid core–annular flow in the thin annulus limit, for axisymmetric disturbances with wavelengths large compared to the annulus thickness, h0 , are the focus of this investigation. A base shear flow affects the interfacial surfactant distribution, thereby inducing Marangoni forces that, along with capillary forces, affect the fluid–fluid interface stability. The resulting system's stability differs markedly from that of the same system with zero base flow. In the thin-annulus limit (the ratio ε of the undisturbed annulus thickness to core radius tends to zero), common in applications, a scaling and asymptotic analysis yields a coupled set of equations for the perturbed fluid–fluid interface shape and surfactant concentration. The linear dynamics of the annular film fully determine these equations, i.e. the core dynamics are slaved to the film dynamics. The theory provides a unified view of the mechanism of stability in three different regimes of capillary number Ca (defined as the product of the core viscosity, μ1 , and the centreline velocity, W0 , divided by the interface tension, σ∗0 , that corresponds to an undisturbed (signified by the subscript 0) uniform surfactant concentration, Γ∗0 ). In the absence of a base flow or in the limit of small Ca(≪ε2) , Marangoni forces deriving from non-uniformities in the interface concentration of insoluble surfactants oppose the net capillary forces. These latter forces normally stabilize the longitudinal curvature and destabilize the circumferential curvature of perturbations to the interface. In the limit of large Ca(≫ε2) , Marangoni forces destabilize disturbances with wavelengths that are large compared to the annulus thickness. For moderately small Ca(∼ε2) , increasing the Marangoni number Ma (defined as the product of (−∂σ∗/∂Γ∗)0 and Γ∗0 , divided by μ1W0) from zero increases the growth rates of all disturbances (with wavelengths ≫h0) and, consequently, reduces the marginal wavelength below that typical of the capillary instability. However a further increase in Ma eventually reverses these trends. A very large value for Ma stiffens the interface, which opposes any local variation of the tangential velocity along the interface, and this is true whether or not there is a base flow. In the limit of infinite Ma, the growth rate of the instability is 1/4 of that of the clean interface and the marginal wavenumber, non-dimensionalized by the undisturbed core circumference, returns to its clean interface (capillary) value of 1. All trends are explained physically.
• Linear stability of a surfactant-laden annular film in a time-periodic pressure-driven flow through a capillary. Wei, Hsien-Hung; Halpern, David; Grotberg, James B. (2005). 285(2) 769–780.

  This paper analyzes the effect of surfactant on the linear stability of an annular film in a capillary undergoing a time-periodic pressure gradient force. The annular film is thin compared to the radius of the tube. An asymptotic analysis yields a coupled set of equations with time-periodic coefficients for the perturbed fluid–fluid interface and the interfacial surfactant concentration. Wei and Rumschitzki (submitted for publication) previously showed that the interaction between a surfactant and a steady base flow could induce a more severe instability than a stationary base state. The present work demonstrates that time-periodic base flows can modify the features of the steady-flow-based instability, depending on surface tension, surfactant activity, and oscillatory frequency. For an oscillatory base flow (with zero mean), the growth rate decreases monotonically as the frequency increases. In the low-frequency limit, the growth rate approaches a maximum corresponding to the growth rate of a steady base flow having the same amplitude. In the high-frequency limit, the growth rate reaches a minimum corresponding to the growth rate in the limit of a stationary base state. The underlying mechanisms are explained in detail, and extension to other time-periodic forms is further exploited.
• Monte Carlo Methods in Bayesian Computation Chen, Ming-Hui; Shao, Qi-Man; Ibrahim, Joseph George in Springer Series in Statistics (2000). Springer, New York.

  Sampling from the posterior distribution and computing posterior quanti­ ties of interest using Markov chain Monte Carlo (MCMC) samples are two major challenges involved in advanced Bayesian computation. This book examines each of these issues in detail and focuses heavily on comput­ ing various posterior quantities of interest from a given MCMC sample. Several topics are addressed, including techniques for MCMC sampling, Monte Carlo (MC) methods for estimation of posterior summaries, improv­ ing simulation accuracy, marginal posterior density estimation, estimation of normalizing constants, constrained parameter problems, Highest Poste­ rior Density (HPD) interval calculations, computation of posterior modes, and posterior computations for proportional hazards models and Dirichlet process models. Also extensive discussion is given for computations in­ volving model comparisons, including both nested and nonnested models. Marginal likelihood methods, ratios of normalizing constants, Bayes fac­ tors, the Savage-Dickey density ratio, Stochastic Search Variable Selection (SSVS), Bayesian Model Averaging (BMA), the reverse jump algorithm, and model adequacy using predictive and latent residual approaches are also discussed. The book presents an equal mixture of theory and real applications. Similar content being
