Early Longitudinal Brain Network Changes in Huntington's Disease Before Clinical Motor Onset

open access: yesMovement Disorders, EarlyView.
Abstract Background Longitudinal studies of seed‐based functional connectivity (SBFC) in young adult Huntington's disease gene‐expanded (HDGE) individuals are rare, and none, to our knowledge, have examined adult cohorts decades from predicted clinical motor diagnosis.

Demo 18-11 Rectifier Circuit

open access: yes, 2001
This demonstration illustrates the operation of a "bridge rectifier" circuit. The output of the bridge rectifier includes inductive and capacitive filters and a resistive load, as shown in Figure 1.

Drivers of stability in plankton communities: dominance, asynchrony, and averaging effects across temporal, spatial and trophic scales

open access: yesOikos, EarlyView.
The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine

Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.

A synchronous rectifier for isolated forward DC-DC converters, integrated in a high-voltage smart-power IC technology

open access: yes, 2012
The synchronous rectifier in isolated forward DC-DC converters is traditionally built with discrete DMOS power transistors driven directly from the secondary winding of the pulse transformer.

Remote Sensing‐Based Identification of Habitat Loss for Herbivorous Waterbirds Driven by Wetland Inundation Alterations

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We present a deep learning framework integrating remote sensing and SHAP interpretation to map 22‐year habitat dynamics of herbivorous waterbirds in Dongting Lake. Results show nearly 50% habitat loss, driven primarily by hydrological recession timing rather than static inundation extent.

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Active clamped ZVS forward converter with soft-switched synchronous rectifier for maximum efficiency operation

open access: yes, 1998
An active-clamped, zero-voltage switched forward converter equipped with a soft-switched synchronous rectifier is designed and implemented for some low output voltage applications where maximized efficiency is of utmost importance.

Integration of Refractive Microlenses on BP/MoS2 Photodiodes for Enhanced Infrared Photodetection

open access: yesSmall, EarlyView.
This study demonstrates the successful integration of black phosphorus/molybdenum disulfide infrared photodetectors with refractive microlenses to significantly enhance detection. The design achieves a 20‐fold photocurrent enhancement, enabling a room‐temperature detectivity of 1.83 × 109 cmHz1/2W−1, and demonstrates high‐resolution (1023 × 768) single‐
