A unified matrix-vector representation is developed of such solution concepts as the core, the uncovered, the uncaptured, the minimal weakly stable, the minimal undominated, the minimal dominant and the untrapped sets. We also propose several new versions of solution sets.

The "sweep effect", the most well-known consequence of the multiple non-transferable vote system, is inconsistent. This may be related to the broad voting opportunities provided by the electoral system, which facilitate the formation of diverse voting strategies. In this study, these strategies are classified based on the prevailing models of candidate selection by voters and ...

Automated microscopic image analysis is essential for quantitative microbiology, yet manual acquisition and generic recognition models struggle with morphological variability and scene artifacts. We address both ends of this pipeline. First, we present a low-cost, open-source acquisition system, based on an Arduino UNO R3 microcontroller and NEMA 17 stepper motors, that automates focusing, magnification, and ...

Enterprises planning material requirements must account for multiple sources of uncertainty. Considering the impact of yield uncertainty is of prime importance to decision-makers. To mitigate the effects of random yield on the continuity of manufacturing operations, we propose establishing a reserve stock to prevent shortages due to defective items within safety stock levels. If no ...

This article explores the role of the term “tolerance” in Russian presidential discourse, 2000-2020. The word became de-politicized (used equally in liberal and in conservative contexts), functioning as a buzzword and as a symbol. As a buzzword, it stood “for all good things” and denoted the positive dynamics in Russia’s nationalities and foreign policies; as ...

In 2006, a “tolerance policy” was launched in St. Petersburg to address the growing xenophobia and the need to integrate labor migrants. Applying a bottom–up perspective, this study finds that this policy was symbolic – aimed at changing public attitudes, not at providing material outcomes. The direct implementers (the street-level bureaucracy), operating under governmental constraints, ...

DreamBooth-style personalization, which often relies on one or a few images, can memorize context (background, pose, lighting) rather than learning the subject’s identity, thereby reducing fidelity and limiting prompt-driven edits. P-LoRA (Probability LoRA) is introduced as a training-time modification that biases diffusion timestep sampling and utilizes importance weights, ensuring that the overall objective remains unchanged. ...

The stability of formal concepts and its generalization as robustness are considered in the paper. We use an approximation of stability in the form of Δ-measure for fast calculations. A computationally efficient method for calculating robustness based on subcontexts is presented. We also present a new method to analytically evaluate the number of preimages for ...

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

Transformer-based Large Language Models (LLMs) rely on Key-Value (KV) cache to accelerate autoregressive decoding, but memory and compute requirements still grow with context length, limiting deployment on resource-constrained devices. Existing training-free KV cache compression methods mainly rely on attention-driven retention heuristics, which may under preserve structurally informative tokens under tight cache budgets, especially when such ...

The impact of state subsidies on Russia's post-Soviet dairy output remains controversial; this study provides an empirical analysis of that relationship. Using an unbalanced panel dataset of 123 dairy enterprises in the Leningrad Region spanning the period from 2010 to 2023, we employ stochastic frontier analysis to assess these relationships. The results indicate that subsidies ...
