Harmonic Suppression in Active-Clamped High-Frequency Link Inverters Under Non-Unity Power Factor Loads

Bowen Gu, Shuang Rong, Wanlin Guan, Huaiyu Guo et autres

High-frequency link inverters (HFLI) inherently suffer from voltage ringing, and the issue becomes more severe under non-unity power factor loads. Although active clamping circuits can effectively suppress the voltage ringing, they cause severe distortion in the output voltage and current waveforms under …

GSDNet: ground sample distance aware network for remote sensing object detection

Shihao Yu, Yifan Dong, WANG Zhiguo, Yun Su

Oriented object detection in remote sensing imagery is fundamentally challenged by cross-resolution scale ambiguity, where objects with identical physical sizes may exhibit drastically different pixel extents under varying Ground Sample Distance (GSD). Conventional detectors primarily operate in the pixel domain and thus …

Vertical GaN-on-Si MOSFET/JBS-based Monolithic Bidirectional Switch

Y Y, Changfa Sun, Yifan Dong, Zi Wang et autres

We demonstrate the first enhancement-mode (E-mode) vertical GaN-on-Si monolithic bidirectional switch (M-BDS). The M-BDS employs a pair of anti-series connected vertical GaN MOSFETs with integrated freewheeling quasi junction-barrier Schottky (JBS) diodes, in which Nitrogen ions were implanted at the bottom/sidewall of the …

Resilient Multi-Agent Deep Reinforcement Learning for Routing Control via Traffic Cost Fields

Yifan Dong, Huachun Tan, Xinjie Zhou, Peifeng Li et autres

Urban road networks frequently experience recurrent congestion and non-recurrent disruptions, where individually optimal routing can degrade system-level efficiency under mixed compliance. Naive shortest-path guidance can be overly myopic in coupled traffic systems. As congestion is shaped by collective route choices, it may …

A Self-Reinforcing Prototype Framework to Mitigate Pseudo-label Degradation in Semi-Supervised Remote Sensing Segmentation

Wenli Sun, Yifan Dong, Yun Su, Yang Zhao

Semi-supervised semantic segmentation (SSSS) has emerged as an effective strategy to alleviate the dependence on costly pixel-level annotations in remote sensing imagery by exploiting limited labeled data alongside abundant unlabeled samples. However, conventional confidence-based pseudo-labeling often produces noisy and semantically inconsistent supervision, …

Large Language Model-Guided Structural Alignment Domain Adaptation for Open-Set Remote Sensing Scene Classification

Yang Zhao, Gefei Zhang, Jiaqi Liang, Hancheng Ma et autres

For open-set domain adaptation (OSDA) in remote sensing scene classification, it is essential to establish precise semantic boundaries for different scenes. Existing vision–language models usually achieve OSDA with fixed templates based on category labels. However, such templates lead to coarse category representations, …

From Pixels to Meters: Ground Sampling Distance Priors for Remote Sensing Detection

Shihao Yu, Yifan Dong, Yun Su, Yang Sheng Zhao et autres

Object detection in remote sensing imagery is challenging because targets often appear at markedly different scales and may become visually similar when the image resolution varies. A key advantage of remote sensing imagery is that each image provides a ground sample distance …

The impact of action video game experience on visual selective attention in deaf middle school students

Ting Cui, Dongmao Ye, Yifan Dong, Huina Gong et autres

Introduction: Previous studies have shown that congenital deafness enhances peripheral visual processing but may reduce attention to central stimuli. In contrast, action video game experience has been shown to improve top-down attentional control and resistance to distraction. However, it remains unclear whether …

Isoacteoside alleviates LPS-induced depressive-like behaviors in mice by inhibiting neuroinflammation through regulating microglial polarization and oxidative stress

Jiajia Bi, Hui Zhang, Wei Jia, Xuhui Huang et autres

Recent studies have demonstrated a close association between neuroinflammation and depression. Isoacteoside (ISO) has recently been reported to exhibit anti-inflammatory properties. However, the effects of ISO on neuroinflammation-induced depression and its underlying mechanisms have not been fully elucidated. This study aimed to …

DMS-MIA: disk replay-based and multi-metric sequence membership inference attack on TEE-protected machine learning models

Yifan Dong, Wei Feng, Hao Li, Min Zhang et autres

随着机器学习即服务 (MLaaS) 的广泛应用, 其数据隐私问题日益凸显. 可信执行环境 (TEE) 通过硬件隔离为 MLaaS 提供了强大的保护, 尤其在防止模型参数泄露和训练数据泄露方面具有显著优势. 这种隔离机制使得主流的成员推理攻击 (MIA) 方法面临挑战: 由于攻击者难以直接访问模型内部参数和状态, 且受到查询频率的严格限制, 现有 MIA 方法在 TEE 下效果不佳. 然而, 本文发现并利用了 TEE 保护下 MLaaS 存在的一个新型攻击面, 提出了一种名为 DMS-MIA (Disk Replay-based Multi-metric Sequence Membership Inference Attack) 的成员推理攻击方法. 该方法的核心思想在于, 攻击者利用对宿主机及虚拟化管理程序的控制权, 对 TEE 保护下机密虚拟机的加密磁盘进行周期性快照与重放, 获取MLaaS模型训练过程中的中间状态的输出.随后, …

The HERD calorimeter: prototype response to high energy nuclei

O. Adriani, G. Ambrosi, M. Antonelli, Yonglin Bai et autres

Abstract HERD is a space-borne calorimetric experiment that aims to extend current direct measurements of cosmic rays to the PeV energy range. The main feature of the instrument is its ability to measure particles coming from all directions, with the main detector …
