Stability of input voltages of a three-level inverter NPC fed by photovoltaic sources

Revue des Énergies Renouvelables, 2012
In this paper we study the stability of input voltages of the cascade consisting of a photovoltaic inverter and a three-level structure NPC, feeding a synchronous machine with permanent magnets (PMSM) commissioned by the speed command flow oriented.

An integrated forest‐to‐market approach to promote lesser‐known timber species (LKTS) in a domestic timber market in the Congo Basin

PLANTS, PEOPLE, PLANET, EarlyView.
In the Congo Basin, domestic timber markets account for ~40% of timber consumption, yet demand is concentrated on a few high‐value species also sought after on international markets, raising concerns about their long‐term availability. We combine market, wood, and forest data to assess the potential of lesser‐known timber species (LKTS) to support a ...

Thermal characteristic research of associated power devices based on three-level inverters and power-loss calculation

Case Studies in Thermal Engineering, 2018
To reduce the size and improve the power density of three-level inverters, two or more associated power devices are assembled on the same heatsink, which, however, has a great influence on the thermal characteristics of heatsink because of heat ...

New estimation methods for diagnostic classification models

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract This paper introduces a new class of estimators for cognitive diagnosis models (CDMs) based on the Cressie–Read family of ϕ$$ \phi $$‐divergences. Focusing on the loglinear CDM (LCDM), for which joint maximum likelihood estimation (JMLE) has been shown to be consistent, we propose a joint minimum divergence estimation (JMDE) framework.

Transcriptomic profiling of subpopulations of mouse embryonic subplate neurons

Journal 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 ...

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

Immunology, Volume 179, Issue 4, Page 579-593, December 2026.
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 ...

A New Physics‐Constrained Neural Network Approach to Retrieve CH4 Vertical Profiles From Hyperspectral Infrared Data

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Methane (CH4 ${\text{CH}}_{4}$) is a critical greenhouse gas, and accurate monitoring of its vertical distribution is essential for understanding its radiative impact and identifying emission sources. This paper introduces a novel methodology using a physics‐constrained neural network based on soft constraints to retrieve CH4 ${\text{CH}}_{4}$
