Summary: This paper discusses the significance of categorizing causal effects into efficient, formal, material, and final causation, and their relevance in biology and technology. Together, they provide the basis for emergent levels in the hierarchy to have causal powers, emphasizing the importance of causal closure when considering upward and downward interactions.

Summary: This paper focuses on redefining the essence of powers, proposing the dynamical operator account of powers. According to this account, the causal role of powers lies in ensuring the transition from a stimulus to a manifestation. This functional activity is the metaphysical fulcrum around which counterfactual-based causation revolves, providing a better understanding of the knowability, modality, and directedness of powers.

Summary: Integrated information theory (IIT) and its Python software package PyPhi are used for causal analysis of systems with multi-valued elements, revealing general causal properties of random networks. The tools were also applied to analyze a non-binary regulatory network model p53-Mdm2, with a discussion on binarization methods.

Summary: This article introduces a new set representation called the hybrid zonotope, which is equivalent to the union of 2N constrained zonotopes by adding N binary zonotope factors. The main contribution is a closed-form solution for exact forward reachable sets of discrete-time, linear hybrid systems modeled as mixed logical dynamical systems. The proposed approach captures the worst-case exponential growth in the number of convex sets required to represent the nonconvex reachable set while exhibiting only linear growth in the complexity of the hybrid zonotope set representation. Numerical examples demonstrate its ability to compactly represent nonconvex reachable sets with an exponential number of features. Furthermore, it is shown to be closed under linear mappings, Minkowski sums, generalized intersections, and halfspace intersections.

Summary: In this paper, a new method is proposed for learning multi-valued dynamic systems from interpretation transition (LFIT) that can capture a wide range of semantics. The correctness of the method is demonstrated through theoretical results, and practical evaluation is performed on benchmarks from biological literature.

Summary: This article compares various dynamical dark energy models using different observational data and discusses the alleviation of H-0 tension. Bayesian evidence analysis shows that all models perform better than Lambda CDM scenario, with the CPL model being the best in fitting the data and solving H-0 tension. However, the tension reappears when considering the baryon acoustic oscillations data, not supporting the dynamical dark energy solution.

Summary: This paper presents a detailed survey on models and methods of investigating logical dynamical systems (LDSs), which have wide applications in gene regulation, game theory, digital circuits, and so on. The paper covers preliminary results on LDSs and semi-tensor product (STP) method, new developments on modeling complex LDSs, and control design techniques of LDSs.

Summary: This paper presents a method for reconstructing unidirectional chaotic synchronized networks based on average integrated causation entropy. By injecting random information into the individual systems and predicting the network structure during the process of re-synchronization, the algorithm successfully reconstructs the structure of chaotic dynamical systems.

Summary: This paper proposes a new methodology for the path planning of a fleet of AGVs to improve the flexibility, robustness, and scalability of the AGV system. The methodology mathematically describes the transport process using a mixed logical dynamical (MLD) model and utilizes model predictive control and 0-1 integer linear programming to dynamically determine collision paths and solve the optimization problem. An ADMM-based decomposition technique is developed to coordinate the AGVs and reduce computational burden, allowing for real-time decisions. The proposed methodology is tested on industrial scenarios and proves effective in achieving high transport productivity with low computational burden.

Summary: Explanations for global patternings in species diversity have been around since before the field of ecology itself. However, the generation of new species-area theories far outweighs their falsification, leading to a centuries-old accumulation of species diversity theories. Research suggests that one of the earliest and most consistent patterns in species diversity is not solely an ecological phenomenon, and the range of potential ecological mechanisms is too vast for hypothesis falsification. Broad-scale aggregation patterns in ecological and non-ecological data suggest a statistical distribution rather than discerning between ecological and non-ecological mechanisms. The study advocates for prioritizing the falsification of broad-scale diversity distribution hypotheses over the generation and parameterization of new ones.

Summary: The study proposes two compartment models to investigate disease transmission dynamics, applies them to the COVID-19 pandemic, explores the potential impact of interventions, and aims to provide insights into future healthcare demand. The analysis focuses on models with and without vital dynamics, studying the global stability of disease free equilibrium and existence of endemic equilibrium, as well as addressing the final epidemic size rigorously. The models are applied to estimate the basic reproduction number and final epidemic size of disease using data from confirmed COVID-19 cases in Canada and Newfoundland & Labrador province.

Summary: The paper discusses Miguel Hernan's perspective on the distinction between observational studies and randomized controlled trials, arguing that both can produce associations that can be interpreted as causal, but trials have a semantic advantage. The author proposes a solution to this issue, but points out that the new restrictions fail their own standards of meaningfulness.

Summary: This paper proposes a real-time fault diagnosis method for a three-phase grid-connected inverter using a mixed logic dynamic model and finite control set model predictive control. The method can quickly and accurately identify the fault location without the need for extra sensors and calculation resources.

Summary: New intermetallic antiperovskites (Y3AlN and Y3GaN) were studied to confirm their synthesis possibility. Two calculation methods (FP-LAPW and PW-PP) were used, which gave similar and negative formation energy values, indicating their energetic stability. The mechanical stability was confirmed by elastic stiffness constants Cij, and the dynamical stability was confirmed by phonon dispersion curves. Analysis of vibrational behaviors revealed the metallic nature of Y3AlN and Y3GaN, primarily due to Y-d states. QTAIM analysis identified four bonds, with (Al,Ga)-(Al,Ga) and (Al,Ga)Y bonds classified as metallic, while (Al,Ga)-N and Y-N bonds were categorized as dative.

Summary: This article examines the nationwide protests that took place in Russia in 2017-2018, focusing on six specific events organized by different anti-systemic opposition leaders and organizations. The analysis explores the turnout, geographic scope, and framing strategies used to mobilize the protesters. It concludes that appropriate framing is crucial for successful protest mobilization, and that changes in protest frames contribute to the dynamics of turnout.

Summary: The article introduces a new framework for understanding strategic culture based on semiotic theory, particularly Charles Peirce's theory. This framework helps to resolve the controversy surrounding the relationship between culture-as-ideas, culture-as-artefacts, and culture-as-behaviour in strategic culture. It also allows for the study of how strategic cultures are reproduced through various means, not just verbal discourse. The article provides examples from Russian strategic culture to illustrate the application of this framework.

Summary: Our research shows that while there is a growing ambition in international relations studies to provide predictions, the focus on developing concrete predictive scenarios is consistently overlooked in favor of other objectives. The proportion of idioscopic predictions remains small, with only a limited number of studies developing concrete narratives or specifying determinate time periods. This indicates that the critical claims made 20 years ago about the lack of attention to developing predictive scenarios in IR are still relevant today.
