Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

Energy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...

Evaluation of Interconnection Configuration Schemes for PV Modules with Switched-Inductor Converters under Partial Shading Conditions

Energies, 2019
Partial shading on photovoltaic (PV) arrays reduces the overall output power and causes multiple maximas on the output power characteristics. Due to the introduction of multiple maximas, mismatch power losses become apparent among multiple PV modules ...

Early Internationalization: A Meta‐Analysis of Antecedents, Dimensions, and Performance

Journal of Management Studies, EarlyView.
Abstract More than three decades after Oviatt and McDougall’s pioneering 1994 paper ‘Towards a theory of international new ventures’, the study of early internationalizing firms continues to captivate international business scholars. The research questions we address involve the antecedents of early internationalization, the dimensions of this ...

Structural Role and Mechanical Impact of Zirconia in Lithium Disilicate Glass

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
The effect of ZrO2 addition on the structure, topology, and mechanical properties of lithium disilicate glass is investigated using topological constraint theory (TCT), molecular dynamics simulations, and experiments. Zirconia acts as a network former, increasing packing density, rigidity, hardness, and elastic modulus.

Experimental Characterization and Modeling of High Hole Mobility GeSn Quantum Wells: The Role of Alloy Disorder Scattering

Small Science, Volume 6, Issue 4, April 2026.
This study reports record‐high hole mobility in undoped GeSn quantum wells, validated through magnetotransport measurements. By modeling the transport properties, the authors discover that alloy scattering in their material is significantly weaker than predicted for random alloys and previously studied materials.
