Few-Shot Aircraft Door Detection with Visibility-Aware Geometric Regularization

Aircraft-door detection is a key perception component for automated passenger boarding bridges, but its performance can degrade substantially under limited annotations, illumination changes, partial occlusion, and viewpoint variation. To address this problem, we propose a multi-c...

Cross‐Phase Impurity–Interphase Regulation for Suppressing Thermally Accelerated Failure in Ni‐Rich Pouch Lithium‐Ion Batteries

ABSTRACT Practical LiNi 0.8 Co 0.1 Mn 0.1 O 2 ||graphite pouch cells suffer rapid degradation under thermal stress because liquid‐phase impurity reactions, electrode interphase failure, and cathode–anode cross‐talk are tightly coupled. However, most strategies are designed to add...

Two-dimensional angstrom two-point inversion method for measuring the in-plane dynamic thermal diffusivity of flat-plate devices

This paper proposes a two-dimensional Angstrom two-point inversion method for measuring the in-plane dynamic thermal diffusivity of flat-plate devices such as vapor chambers under periodic thermal excitation. The method overcomes the limitations of steady-state thermal resistance...

A continuous spiral-spring triboelectric nanogenerator for energy harvesting and self-sensing under ultra-low-frequency rotation

Self-powered monitoring of slowly rotating components is hindered by the small relative speed and limited installation space available to conventional rotary triboelectric nanogenerators (TENGs). Here, a continuously driven unidirectional rotary TENG (CDUR-TENG) is developed by i...

A few-shot learning framework using multimodal rheological features for local prepreg thickness prediction in multilayer PCBs

As multilayer printed circuit boards (PCBs) move toward high-frequency and high-speed applications, back-drilling stub control and impedance matching have become critical for signal integrity. Their accuracy is strongly governed by the micrometer-level stability of prepreg (PP) d...

A semi-supervised deep learning framework (TBMNet) for automatic tumor budding quantification: real-world validation and clinical utility in stage II colorectal cancer

Abstract Background Tumor budding (TB) is a clinically important prognostic marker in colorectal cancer (CRC), but its assessment remains subjective and its biological basis is incompletely understood. We developed an artificial intelligence (AI)-based TB evaluation framework and...

Extreme‐Fast‐Charging Li‐Ion Batteries via Activation‐Energy Regulation With a Li 3 PO 4 ‐Li 2 SO 4 ‐Rich Solid Electrolyte Interphase

ABSTRACT Extreme‐fast‐charging (XFC) batteries are essential for widespread electric vehicle adoption. Although heating‐assisted charging enables ultrafast charging at elevated temperatures (e.g., 65°C), it increases the risk of thermal runaway. Lowering the activation energy of...

Seismic performance and coupling mechanism of modular concrete shear wall structures under multi-directional excitation

To reveal the seismic coupling mechanism of modular integrated construction (MiC) concrete shear wall structures under multi-directional excitation, this paper adopts shaking table test data of a full-scale three-storey typical MiC concrete shear wall unit subjected to unidirecti...

Safety and efficacy of the automated liquid-phase embryo storage, Hatchferti: a pilot study

To date, no fully automated liquid-phase embryo tank has been implemented in assisted reproductive technology (ART) laboratory and its impact on the safety and efficacy of embryo storage remains unknown. To evaluate its performance, the Hatchferti group (HG) stored a total of 230...

Structural and Biochemical Analysis of Human Schlafen5 Reveals the Molecular Basis of Its Anti-Tumor Function

Background: Schlafen5 (SLFN5) is an IFN-inducible member of the SLFN protein family involved in immune regulation, viral inhibition and tumor control. Recently, SLFN5 was suggested to inhibit the invasion of many kinds of malignant cells, and its expression positively correlates...

Hole-extraction embedded ultrathin donor realized highly homogenized dense self-assembled monolayers enabling organic photovoltaic modules with a certified efficiency of 16.1%

Abstract Achieving uniform, large-area interfacial layers remain a definitive barrier to the scalable manufacturing of solution-processed organic photovoltaics (OPVs). Conventional self-assembled monolayers (SAMs) frequently suffer from stochastic aggregation and incomplete cover...

Interpretable machine learning model for predicting the ICU readmission of patients after coronary intervention

To develop and validate an interpretable machine learning (ML) model integrated with inflammatory indicators for predicting ICU readmission in patients after coronary intervention (PCI/CABG). We used retrospective data from MIMIC-IV (training, 2196 patients) and MIMIC-III (extern...

A Study on the Metaphor Judgement and Comprehension of EFL in Chinese Universities—Taking Senior English Major Students as Example

ABSTRACT: Metaphor comprehension remains a central concern in linguistic research. This study investigates metaphor judgment and comprehension among senior English majors from five types of Chinese universities—Project 985, Project 211, language-featured, normal, and basic public...

A Biofabricated Human Acinus‐on‐a‐Chip Unveils Mechanotransductive Drivers of Ventilator‐Induced Lung Injury via Decoupling Volutrauma and Barotrauma

Ventilator-induced lung injury (VILI), an iatrogenic complication of mechanical ventilation, remains poorly understood due to the absence of physiologically relevant in vitro models, impeding targeted therapy development. Here, we engineer a bioinspired acinus-on-a-chip model rec...
