Detecting Plateau Zokor (Eospalax baileyi) Mounds in UAV Imagery of Alpine Meadows Using Deep Learning Algorithms

Remote Sensing in Ecology and Conservation, EarlyView.
We developed PZM‐YOLO to automatically detect plateau zokor mounds in UAV imagery of alpine meadows. The model achieved reliable detection of small and densely distributed mounds under complex backgrounds, outperforming the baseline YOLOv5s. This framework supports mound counting, mound position, rodent impact assessment, and grassland restoration ...

A General Multiscale Pyramid Attention Module for Ship Detection in SAR Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Compared with large-scale ships, small-scale ships occupy few pixels and have low contrast, so it poses a great challenge to detect multiscale ships in synthetic aperture radar (SAR) images.

Development and Validation of a Next‐Generation Mechanistic Model of the Electric Arc Furnace

steel research international, EarlyView.
This study presents a next‐generation mechanistic model of the electric arc furnace (EAF). It describes equations for all crucial processes appearing during the steel‐recycling process in an EAF, i.e., thermal, mass, and chemical. The model was parameterized and validated using industrial EAF data.

FMTNet: A Fourier‐Mamba–Transformer Enhanced Network for Medical Image Segmentation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Models based on U‐shaped networks have achieved widespread success in the field of medical image segmentation, but their performance is generally limited by structural bottlenecks in the network. At this stage, feature maps experience a sharp decline in spatial resolution due to continuous downsampling, resulting in significant loss of ...

Submodule Capacitor Voltage Balancing Through High-Frequency-Side Control for Multiport MMC-Based Solid-State Transformers

IEEE Open Journal of the Industrial Electronics Society
This article proposes a novel submodule capacitor voltage balancing control for multiport modular multilevel converter (MMC)-based solid-state transformers. To balance each submodule capacitor voltage, the balancing control is usually applied to the MMC.

Transient Oscillation Suppression Method of Modular Multilevel DC Transformer

IEEE Access, 2020
The modular multilevel DC transformer (MMDCT) is more likely to suffer from transient oscillation, which is caused by insufficient damping of the equivalent RLC circuit with smaller arm resistance and submodule capacitance and may threaten the system ...

Drugst.One DREAM—Drug repurposing through expert annotation and modification

British Journal of Pharmacology, EarlyView.
Background and Purpose Complex diseases often lack an actionable understanding of their underlying causal biological mechanisms, which leads to treating symptoms rather than causes. Network and systems medicine define disease mechanisms through disease‐associated genes, their encoded proteins and their protein–protein interactions (PPIs), thus forming ...

PEG400 regulates Falcipain 2 activity through an allosteric mechanism

The FEBS Journal, EarlyView.
Falcipain‐2 can potentially be leveraged as a drug target due to its critical role as a haemoglobinase during the intra‐erythrocytic stage of Plasmodium falciparum. Here, we investigate the regulation of the proteolytic and haemoglobinase activity of falcipain‐2 in the presence of polyethylene glycol.
