Fractional‐Order Impedance Reshaping and Integral Finite‐Time Control for LCL Grid‐Connected Inverters in Weak Grids

ABSTRACT Under extremely weak grids (short‐circuit ratio, SCR < 2), LCL grid‐connected inverters suffer severe wideband resonance and degraded transient performance due to voltage feedforward phase lag and phase‐locked loop (PLL) negative impedance. To circumvent the trade‐off be...

Three decades of microcystin-LR removal in aquatic environments: physical, chemical and biological strategies for environmental detoxification

Abstract Microcystin-LR (MC-LR) contamination from cyanobacterial blooms poses a persistent threat to aquatic ecosystems and human health, necessitating effective removal technologies. This study used visualization analyses to examine global research on MC-LR removal in aquatic e...

Quantitative image feature integrated digital pathology model based on deep learning and machine learning for binary histological severity stratification of ulcerative colitis

The STRIDE II consensus recognizes histopathological healing in ulcerative colitis as a key therapeutic target. This study aimed to develop and internally evaluate a quantitative image-based model for the binary classification of mild versus moderate-to-severe UC based on histopa...

HLR-UFS: Hessian-based Unsupervised Feature Selection using Low-Rank Approximation

Graph-based Laplacian regularization techniques have been extensively applied in unsupervised feature selection due to their capability in capturing the inherent structure of data. However, Laplacian regularization frequently results in a solution that is biased towards a constan...

Beyond Suitability: Mapping Current and Projected Conservation Gaps for Three Rare Pheasants in Karst Landscapes of Southwest China

Climate-driven range shifts may create new environmentally suitable areas, but whether these areas provide favourable habitat conditions or adequate protection remains poorly understood. We assessed conservation gaps for three rare pheasants (Syrmaticus humiae, S. ellioti and S....
