• Fluvio-alluvial source-sink relationships at the Skeleton Coast of northern Namibia: a parametric analysis. Mohren, Joel; Walk, Janek; Krieger, Julian; Römer, Wolfgang; Nguno, Anna; Lehmkuhl, Frank (2026). 14(5) 685–728.

  The hyperarid Skeleton Coast of Namibia hosts a diverse suite of alluvial landforms, often shaped by varying degrees of lateral and distal confinement primarily through fan coalescence, the Atlantic Ocean, and the Skeleton Coast Erg. Considerable heterogeneity also characterises the source areas, as reflected in catchment morphometry, lithology, and coast-perpendicular moisture gradients, where larger inland-draining catchments intercept more precipitation. On the regional scale, this heterogeneity blurs (hydro-) morphometric source-sink relationships between alluvial landforms and catchments, despite overall geomorphic drainage maturity which could imply similar efficacy in source-sink communication. To disentangle these patterns, we mapped 67 drainage systems and obtained a dataset including (hydro-) morphometric, climatic, and geologic parameters for these systems. An exploratory data analysis framework combining cluster and partial correlation analyses was applied to these datasets after quality filtering and outlier removal, retaining 47 alluvial landforms. Three distinct clusters were identified for both alluvial landforms and catchments, with limited matching observed between alluvial landform and catchment clusters. The clearest source-sink coupling is attributed to a cluster of near-coastline fans, spanning much of the study area but with a spatial focus on its northern portion. By contrast, the majority of alluvial landforms form bajadas strongly influenced by the Skeleton Coast Erg, where distal confinement masks simple morphometric scaling. Our results highlight fan confinement as the main driver affecting source-sink relationships at the Skeleton Coast. Fan morphometry appears to be more decisive than catchment properties, with fan gradient (< 1° on average) emerging as a reliable discriminator. No robust lithological or climatic (as inferred from modern climatological data) control on fan morphometry could be identified, although Sentinel-1 radar backscatter indicates more stable fan surfaces south of the Skeleton Coast Erg. Overall, the Skeleton Coast represents a low-dynamics dryland margin where fan gradient provides the most meaningful parameter for source–sink analysis. Least-confined fans show the strongest coupling and thus constitute promising targets for paleoenvironmental reconstruction, while environmental conditions in the southern portion of the study area may have so far provided the most favourable conditions for long-term archive preservation.

• A review on robustness in Machine Learning based Network Intrusion Detection Systems. Wolf, Maximilian; Landes, Dieter; Hotho, Andreas; Schlör, Daniel (2026). 287 112467.

  Modern Network Intrusion Detection Systems require constant adaptation to new attacks, making the application of Machine Learning (ML) based solutions attractive. The application of such systems in real-world applications require robust solutions that work well under data alterations and are robust against adversarial attacks. The literature includes several works focusing on the robustness of (ML-based) Network Intrusion Detection System (NIDS) models, but it remains unclear which aspects of robustness are relevant, well-researched, or need of further investigation. Furthermore, the existing literature lacks a structured overview due to the varying experimental setups, particularly the differences in the benchmark datasets, NIDS models, and the scope of robustness. This work aims to close this gap by reviewing recent studies on the robustness of ML-based intrusion detection from 2021 to 2025, with the goal of structuring the landscape of experimental setups and the varying definitions and scopes of robustness. Our review reveals significantly different setups that hinder result comparison, making it difficult for practitioners to select appropriate approaches and for researchers to establish consistent benchmarks and advance development. To address this, we propose benchmarking setups for robustness in ML-based NIDS systems to enable a systematic comparison of approaches.
• GE-PEFT: Gated Expandable Parameter-Efficient Fine-Tuning for Continual Learning. Omeliyanenko, Janna; Hotho, Andreas; Schlör, Daniel (2026). 115(7) 171.

  In practical use, language models (LM) must efficiently adapt to new tasks and knowledge while avoiding catastrophic forgetting, a requirement that sparked research on continual learning (CL). Despite advances, current CL methods still lack a unified solution that delivers strong knowledge transfer and parameter-efficient capacity management while preventing catastrophic forgetting, which limits effective use of task synergies under tight training and memory budgets. We bridge this gap by introducing Gated Expandable Parameter-Efficient Fine-Tuning (GE-PEFT), a novel approach that shares knowledge of previous tasks through leveraging a single, dynamically expanding PEFT module within LMs while selectively gating irrelevant previous tasks. Our experiments across multiple task-incremental CL benchmarks show that GE-PEFT outperforms existing state-of-the-art CL approaches in both full CL and few-shot settings. Our ablation and parameter sensitivity studies highlight the benefit of each proposed component, demonstrating that GE-PEFT offers a more efficient and adaptive solution for CL in LMs.

  The authors present here results from electrical magnetotransport measurements on microstructures of altermagnetic CrSb in pulsed fields up to 68 T. They study the temperature and field-orientation dependence of magnetic quantum oscillations in combination with first-principles calculations. The observed frequency spectrum agrees well with density functional theory calculations that take spin-orbit coupling into account, without invoking significant \($a\phantom\rule00exd$\) \($h\phantom\rule00exo\phantom\rule00exc$\) band shifts. The findings validate the predicted electronic band structure of CrSb hosting multiple semimetallic bands and a locally alternating spin polarization.

The project is designed to enhance the learning environment through the integration of indoor plants, edible herbs, and ornamental palms, while promoting sustainability, wellness, and experiential learning aligned with the hospitality sector. In addition to this, a correx board with the names and health benefits of all the herbs available in the premise is strategically mounted in the Resource Centre as part of information resources to educate the patrons. The objective of this project is to improve indoor air quality and comfort within the library, create a calming, green, and visually appealing learning environment, introduce edible and herbal plants relevant to hospitality and culinary education, promote sustainability and environmental awareness among students and staff, and enhance institutional branding through green design.
• Responsibility Without Superiority: An Epistemic Account of Human Duty in the Anthropocene. Gertler, Martin (2026). (2026001)

  This article develops the concept of “epistemic obligation” as a new foundation for human responsibility in the Anthropocene, one that is based neither on ontological superiority nor on instrumental utility. It demonstrates that responsibility follows directly from the epistemic capacity to anticipate consequences, thereby resolving the tension between biological equivalence and the necessity of human action. The model offers a theoretical framework for a life-centered ethics that provides concrete guidelines for political decision-making and intergenerational justice without hierarchical assumptions.

  The development of future forest deadwood is uncertain, as processes related to deadwood formation (i.e., tree growth and mortality) as well as deadwood decomposition are simultaneously impacted by climate change. To elucidate future deadwood dynamics under scenarios of climate change, we combined a map of current global deadwood stocks with tree growth and mortality rates simulated by five dynamic global vegetation models and a function of climate-dependent deadwood decomposition derived from a global experiment. Deadwood dynamics intensified throughout the 21st century, with both inputs and outputs to global deadwood carbon pools increasing as a result of climate change. However, deadwood formation increased on average 5.0% more strongly than decomposition, suggesting an overall increase in global deadwood in the coming decades. As deadwood is an important nexus of forest carbon and biodiversity, we call for a stronger focus on deadwood in forest policy and management.

• Programmed ribosomal frameshifting triggers translational stress to promote viral replication.

S0092–8674(26)01004.

  Programmed ribosomal frameshifting (PRF) is a conserved viral strategy for expressing polyproteins from compact genomes. Although PRF is traditionally viewed as a structural mechanism, here we show that it functions as a regulatory signal that rewires host translation in favor of viral replication. A minimal SARS-CoV-2 PRF element is sufficient to activate the GCN2 arm of the integrated stress response (ISR) independently of the canonical ISR sensor ZAKα. This activation serves as a temporal switch during early infection to shut off host translation and is required for viral propagation in cells and human airway organoids. Proteomic and genetic screens identify DRG1 and IGF2BP3 as key mediators of PRF-induced GCN2 activation. We further show that this PRF-GCN2 axis is conserved in human immunodeficiency virus (HIV)-1 and West Nile virus, highlighting its broad relevance across RNA viruses. These findings reveal a sophisticated mechanism of viral translational control, highlighting PRF as a stress-inducing module that enhances viral replication.
• Coordinated alternative splicing decisions via stepwise exon definition. Kristofori, Panajot; Xiao, Zijie; Braun, Simon; Busch, Anke; Zarnack, Kathi; König, Julian; Legewie, Stefan; Li, Congxin (2026). 54(9) gkag464-.

  Alternative splicing of pre-mRNA is a fundamental step in human gene regulation, and aberrant splicing is frequently linked to complex diseases, including cancer. All splicing events, such as skipping or inclusion of an alternative exon (AE) and intron retention (IR), are regulated by a common molecular machinery, the spliceosome. However, it remains elusive how the spliceosome coordinates different splicing decisions. Here, we analyzed a large-scale mutagenesis screen and transcriptome-wide RNA sequencing data to show that intron retention adjacent to alternative exons most commonly occurs at intermediate inclusion levels. Using data-driven mathematical modeling, we revealed that multistep exon recognition mediated by spliceosome assembly and maturation explains the observed AE-IR dependency for cis-acting sequence mutations and upon knockdown of trans-acting RNA-binding proteins. Furthermore, we found that multistep exon recognition is commonly perturbed in a transcriptome-wide manner in cancer cells, which leads to the coordinated deregulation of IR and AE decisions. In total, our work suggests that stepwise alternative exon recognition by the spliceosome coordinates AE inclusion and the retention of flanking introns, which may facilitate the search for common molecular mechanisms for mis-splicing in cancer.
• RNA motifs, RNA structure, and motif context analyzed by RNAanalyzer3. Akash, Aman; Balkenhol, Johannes; Liang, Chunguang; Zarnack, Kathi; Dandekar, Thomas (2026). 54(W1) W188-W195.

  RNAanalyzer3 ("RNA analyzer cubic"; https://rnaanalyzer.bioapps.biozentrum.uni-wuerzburg.de) substitutes the frequently consulted current RNAanalyzer webserver (https://rnaanalyzer-old.bioapps.biozentrum.uni-wuerzburg.de). RNAanalyzer3 is free/open via the secure HTTPS protocol, with example data, help and tutorial, web-link to results, and rich data output. We combine a general detailed structure analysis with motif analyses. It accepts either a single plain-text nucleotide sequence or batch submission in FASTA format, which can be pasted or uploaded as a FASTA file. Our tool (i) has up-to-date software and operating systems, (ii) combines diverse RNA motif analyses with RNA structure prediction, (iii) puts found motifs into structural context, and (iv) offers dedicated tools for probing RNA-protein binding interactions. RNAanalyzer3 links motif searches to Rfam and miRNA search to miRbase. It focuses on structural features first, looks for stem-loops, hairpins, and specific enrichment regions such as stem-GG pairs, plus AU-rich regions with their locations for easier identification, while providing structural context and interactive RNA structure visualization. A tabulated overview shows all RNA features including structure details, coding potential, untranslated regions (UTRs, including Shine-Dalgarno sequences, Kozak sequences, and polyadenylation signals), transfer RNA (tRNA), microRNA (miRNA), long noncoding RNA (lncRNA), trans-splicing motifs, iron response elements (IRE), riboswitches, small nuclear ribonucleoprotein (snRNP) motifs, and spliceosomal Sm-sites.

• Knowledge and information in the 2030 Agenda indicators Associations, International Federation of Library; Institutions (2026).

  Knowledge and information already appear in a significant share of the 169 targets that accompany the 17 Sustainable Development Goals, with a mixture of explicit and implicit references. However, this is too rarely mirrored in the related indicator framework, creating a risk of not being able to track and so demonstrate the contribution of knowledge and information to development. Where relevant indicators do exist, they often have limited coverage, both of countries and over time. The positive examples that do exist nonetheless show what is possible and offer a basis for thinking both about what more effective indicators might exist now, and/or could be incorporated into future development frameworks.

• Throw, sweep, thrive and belong: A small story narrative analysis of sense of community meanings for elite curler mothers on Instagram. Kulkarni, Shaantanu; McGannon, Kerry R; Harding, Kelly; Schweinbenz, Amanda; Pegoraro, Ann (2026).

  To advance understanding of socially constructed motherhood and sport, researchers are exploring elite athlete mothers’ sporting comebacks on social media (e.g. Instagram). The role of community aspects (e.g. belongingness, trust) linked to athlete mothers’ sporting career negotiation in digital media holds potential to expand understanding of socio-cultural career affordances for these sportswomen. This study explored the sense of community meanings of four Canadian elite curler mothers’ (e.g. (inter)national rankings, winning tournaments) negotiation of sporting career post-partum on Instagram. A total of 217 Instagram posts for each athlete, covering from most recent birth announcements to summer 2024 were segmented into themes related to family, sporting career and community (e.g. curling spaces, fan interactions). Posts were theorized as small stories (e.g. images, everyday moments) shaping big story narrative meaning(s) using dialogical narrative analysis. A big story narrative of growth and stability amidst belongingness was shaped by small stories of striving for excellence and expanding communities and careers . These results provide novel theoretical insight into the normalization of motherhood in elite curling spaces linked with socially constructed community meanings. Small stories revealed tensions intertwined with performance excellence and sporting career expansion, supported through community meanings, for a select few. These findings shed light on motherhood in elite curling, inclusion/equity, maternal rights, and provide future directions for social media research on motherhood and sport.

• A NOVEL MACHINE LEARNING TECHNIQUE FOR CYBERSECURITY NETWORK INTRUSION DETECTION SYSTEM. Ghembaza, Moulay Ibrahim El-Khalil (2026). 18(4) 137–153.

  Network intrusion is the unauthorized access, manipulation, or interruption of computer networks and systems. It comprises a variation of illegal behaviors, such as hacking, virus deployment and data theft. Detecting and blocking intrusions is vital for protecting sensitive data and credentials to ensure the integrity and safety of digital infrastructure. To develop a Machine Learning technique for a cybersecurity Network Intrusion Detection System, this research proposes a novel Cheetah Optimization-driven Intelligent Adaptive Boosting (CO-IAB) technique to protect systems and ensure data identification against threats and breaches by detecting and responding to unauthorized or illegitimate access to computer networks. Initially, the research obtained a dataset that contains a wide range of network intrusion techniques for training the suggested detection model. The collected raw data is pre-processed using Zscore Normalization to improve the quality of the data obtained. The Kernel Principal Component Analysis (Kernal-PCA) algorithm is employed to extract significant features from the processed data. The CO is used to optimize hyperparameters and feature selection for the subsequent IAB network architecture, improving its performance in network intrusions detection by purposely developed Python code. The analysis of the findings is evaluated with metrics parameters such as Recall, Precision, Accuracy and F1- score. The results are cross validated to authenticate the contribution of the proposed prediction model. Experimental findings show that the recommended prediction model has outperformed conventional approaches in IDS to secure network data

  The detection of scenes in literary texts is a recently introduced segmentation task in computational literary studies. Its goal is to partition a fictional text into segments that are coherent across the dimensions time, space, action and character constellation. This task is very challenging for automatic methods, since it requires a high-level understanding of the text. In this paper, we provide a thorough analysis of the State of the Art and challenges in this task, identifying and solving a problem in the training procedure for previous approaches, analysing the generalisation capabilities of the models and comparing the BERT-based SotA to current Llama models, as well as providing an analysis of what causes errors in the models. Our change in training procedure provides a significant increase in performance. We find that Llama-based models are more robust to different types of texts, while their overall performance is slightly worse than that of BERT-based models.

• The role of the PMOC in modulating the deglacial shift of the ITCZ. Liu, Wei; Hu, Aixue (2015). 45(11) 3019–3034.

  Based on an energy-constraint framework, the effect of the Pacific meridional overturning circulation (PMOC) has been investigated on the meridional shift of the intertropical convergence zone (ITCZ). During Heinrich Event 1, the global ITCZ displaces southward in response to a shutdown of the Atlantic meridional overturning circulation (AMOC). However, the PMOC resumes and induces an enhanced northward meridional heat transport (MHT). Further analyses show that the resumption of the PMOC and its associated MHT can relieve the decrease of oceanic cross-equatorial heat transport by the collapsed AMOC and lower the compensating decline of atmospheric cross-equatorial meridional heat transport by 0.09PW, leading to an offset of the southward shift of the global ITCZ by 0.5textdegree. Regionally the developed PMOC does not affect the southward movement of the Atlantic ITCZ much since the latter is dominated by the collapsed AMOC that induces the change of Atlantic MHT. In contrast, the PMOC-induced northward heat transport largely abates the hemispheric temperature contrast in the tropical Pacific and reduces the southward ITCZ shift by as much as 5textdegree in the eastern Pacific.

• THE REDUCTION IN COMPUTATION TIME IN THE COLOR IMAGE DECOMPOSITION WITH THE BIDIMENSIONAL EMPIRICAL MODE DECOMPOSITION APPROACH. Arfia, Faten Ben; Sabri, Abdelouahed; Messaoud, Mohamed Ben; Abid, Mohamed (2012). 2(2) 01–09.

  This paper presents two different approaches in color image decomposition domain with Bidimensional Empirical Mode Decomposition (BEMD). The first approach applies the BEMD on each channel separately and the second is based on interpolation of each channel in the sifting process. The comparison of two approaches shows the same performance of each approach in terms of visual quality, but they do not provide the same results in execution time which presents the most important criteron in real time applications. It was shown that the second BEMD approach based on interpolation of each channel in the sifting process, gives a gain in the point of view the execution time.
