A zero‐current‐transition soft‐switching technique for T‐type NPC three‐level inverter

open access: yesIET Power Electronics, 2023
Based on the commutation property of the T‐type neutral point clamped (T‐NPC) three‐level inverter, a novel zero‐current‐transition (ZCT) soft‐switching topology is proposed.

A PD1‐CD137L Fusion Protein More Potently Enhances Anti‐Tumour Immune Responses Than Targeting PD‐L1 and CD137 Separately

open access: yesImmunology, EarlyView.
A PD1‐CD137L fusion protein converts the immunoinhibitory PD‐L1 to an immunostimulatory signal and is more effective than targeting PD‐L1 and CD137 separately. ABSTRACT Tumour immune evasion frequently involves PD‐L1‐mediated inhibition of T cell activity, limiting the efficacy of PD1/PD‐L1 blockade, particularly in PD‐L1‐low or immunologically ‘cold ...

Transcriptomic profiling of subpopulations of mouse embryonic subplate neurons

open access: yesJournal of Anatomy, EarlyView.
To study gene expression in subpopulations of cortical subplate neurons (Lpar1‐EGFP‐positive and D1B‐positive SpN clusters), we applied gene expression profiling, including bulk microarray analysis, single‐cell RNA sequencing (scRNA‐seq), and Visium spatial transcriptomics, and identified both overlapping and unique gene expression signatures ...

Does State Ownership Impact Corporate Social Responsibility (CSR): A Literature Review on Country Governance

open access: yesBusiness Strategy &Development, Volume 9, Issue 3, September 2026.
ABSTRACT This literature review is the first to focus on how country governance moderates the relationship between state ownership and corporate social responsibility (CSR) outcomes, given the mixed research results. Earlier research has predominantly focused on how state ownership affects CSR performance in regimes lacking Organization for Economic ...

Leveraging Multimodal Large Language Models to Analyse Student Exploration Behaviours in Educational Game Environments

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Video data provides rich opportunities to examine student behaviour in game‐based learning environments, capturing not only observable actions but also subtle indicators of cognitive engagement. However, traditional video analysis is labor‐intensive, and current applications of AI to this task are limited by models trained on ...
