Are there stars in Bluesky after the return of Donald Trump to the White House?
This study examines the shift in the scientific community from X (formerly Twitter) to Bluesky, its impact on scientific communication, and consequently on social metrics (altmetrics). We analysed 14,497 publications from multidisciplinary and Library and Information Science (LIS) journals between January 2024 and March 2025. The results reveal a notable increase in Bluesky activity for multidisciplinary journals in November 2024, likely influenced by political and platform changes, with mentio…

How to Elicit Explainability Requirements? A Comparison of Interviews, Focus Groups, and Surveys
As software systems grow increasingly complex, explainability has become a crucial non-functional requirement for transparency, user trust, and regulatory compliance. Eliciting explainability requirements is challenging, as different methods capture varying levels of detail and structure. This study examines the efficiency and effectiveness of three commonly used elicitation methods - focus groups, interviews, and online surveys - while also assessing the role of taxonomy usage in structuring a…

Evaluating financial tail risk forecasts: Testing Equal Predictive Ability
This paper provides comprehensive simulation results on the finite sample properties of the Diebold-Mariano (DM) test by Diebold and Mariano (1995) and the model confidence set (MCS) testing procedure by Hansen et al. (2011) applied to the asymmetric loss functions specific to financial tail risk forecasts, such as Value-at-Risk (VaR) and Expected Shortfall (ES). We focus on statistical loss functions that are strictly consistent in the sense of Gneiting (2011a). We find that the tests show lit…

A Network-Guided Penalized Regression with Application to Proteomics Data
Network theory has proven invaluable in unraveling complex protein interactions. Previous studies have employed statistical methods rooted in network theory, including the Gaussian graphical model, to infer networks among proteins, identifying hub proteins based on key structural properties of networks such as degree centrality. However, there has been limited research examining a prognostic role of hub proteins on outcomes, while adjusting for clinical covariates in the context of high-dimensi…

techno-political rant
Say what you want about using the right tool for each problem, but there are tools that suck no matter what.
I'm tired of people portraying legit technical criticism as "biased" and "religious", while at the same time they present themselves as tolerant and open-minded (spoiler: for the most part, they aren't).
Almost every day of my life I have to deal with the nasty consequences of ultra-dumb decisions made by the very same people who are obsessed with productivity and criticise all day long whoever pushes for any design that shows any minim amount of care and/or deep thought (mostly via strawmen arguments).
And, of course, unironically: this has a lot to do with capitalism, as many of our other social and economic problems.
They arrive, have a strike of super-productivity for a few weeks/months and then use that as a trampoline to raise through the ranks or abandon ship before having to face the consequences of their technical crimes.
Then others arrive and are obviously slower at that same job... so the uneducated observers start believing that these newcomers aren't as good as the class traitors who wrote the initial nasty code.
To make things worse, if any of these newcomers dare to speak openly about introducing good practices... this ends up creating a new mental association (in the minds of uneducated observers) between "good engineering" and "lack of productivity".
The ones trying to fix the mess are indeed slower, not because they try to do things the right way though, but because they have to waste vasts amounts of time fixing what is objectively broken besides doing the "visible" work.
Most of today's established "super-productive" ones, if they were starting today, would be probably "vibe coders", certainly not what we commonly understand as a programmer. Not because AI-coding is the future, but because they never cared about the trade at all. They were here only for the grift.

GUARD: Constructing Realistic Two-Player Matrix and Security Games for Benchmarking Game-Theoretic Algorithms
Game-theoretic algorithms are commonly benchmarked on recreational games, classical constructs from economic theory such as congestion and dispersion games, or entirely random game instances. While the past two decades have seen the rise of security games -- grounded in real-world scenarios like patrolling and infrastructure protection -- their practical evaluation has been hindered by limited access to the datasets used to generate them. In particular, although the structural components of the…

Stress distribution in elastic disks with a hole under uniaxial compression
This paper investigates the stress and displacement distribution in a two-dimensional elastic hollow disk subjected to distributed diametric loading, extending our previous analysis of concentrated loading [Okamura et al. Strength Mater. 57, 102-114 (2025)]. The study provides deeper insights into the mechanical behavior of materials such as concrete and rock by examining the effects of load distribution on stress localization and displacement patterns. Using elastodynamic theory, we derive the…

Curvature estimates for minimal hypersurfaces in the Heisenberg group
This paper examines minimal hypersurfaces in sub-Riemannian Heisenberg groups. We extend the celebrated Simons formula and Kato inequality to the sub-Riemannian setting, and we apply them to obtain integral curvature estimates for stable hypersurfaces. These results lead to structural conditions that imply a Bernstein-type rigidity theorem for smooth, non-characteristic hypersurfaces in the second Heisenberg group.

Anderson localization induced by structural disorder
We examine the onset of Anderson localization in three-dimensional systems with structural disorder in the form of lattice irregularities and in the absence of any on-site disordered potential. Analyzing two models with distinct types of lattice regularities, we show that the Anderson localization transition occurs when the strength of the structural disorder is smoothly increased. Performing finite-size scaling analysis of the results, we show that the transition belongs to the same universali…

Geological CO$_2$ Storage in Poland: Review of Sequestration Potential, Policy Development, and Socio-Economic Factors
Poland's coal-reliant economy faces challenges in meeting European Union climate mandates. Carbon Capture and Storage (CCS) is pivotal for decarbonizing high-emission sectors (e.g., cement, chemicals, refineries, and steel), enabling substantial CO$_2$ emission reductions while sustaining industrial competitiveness. This multidisciplinary review assesses Poland's CO$_2$ storage potential, integrating geological, regulatory, and socio-economic analyses to evaluate large-scale CCS feasibility. On…
