State-of-health-coupled power sharing in a hierarchical control framework for battery-supercapacitor hybrid energy storage in solar-powered microgrids

Battery-supercapacitor hybrid energy storage systems (HESSs) are widely used in PV-based DC microgrids to compensate renewable intermittency and support DC-bus voltage regulation. However, many existing power-sharing strategies do not directly account for the evolving health cond...

Vertebral heart scale measurements in Asiatic black bears (Ursus thibetanus) and sun bears (Helarctos malayanus)

This retrospective study aimed to establish vertebral heart score (VHS) reference ranges for Asiatic black bear ( Ursus thibetanus ; ABB) and sun bear ( Helarctos malayanus ; SB), and to evaluate interspecific differences and the effects of biological variables on VHS measurement...

Physiologically-aware data generation: A differentiable HMM and frequency-domain Transformer GAN approach

The generation of multivariate medical time series, such as intensive care unit (ICU) trajectories, remains challenging because patient signals are highly heterogeneous, non-stationary, and strongly multimodal. In this paper, we present a methodological proof-of-concept for the s...

Genetic-Algorithm Optimization of Dynamic Efficiency in Bidirectional Porous Functionally Graded Beams

This study develops an analytical–evolutionary framework for optimizing the dynamic efficiency of bidirectional porous functionally graded beams. Touratier’s higher-order shear deformation theory is coupled with a real-coded genetic algorithm. The material-gradation indices in th...

Contribution to the knowledge of the distribution of bats (Chiroptera) in Algeria

Algeria is the largest country in Africa and for the most part has not yet been surveyed for bat species. To contribute to the knowledge of the distribution of Algerian bat fauna, between 2011 and 2026 we surveyed 70 sites from 19 provinces across the country, mostly roost sites...
