A Bio-Inspired Pursuit–Evasion Game and Fixed-Time Safety Control Method for USV Swarm Encirclement

Unmanned Surface Vehicle (USV) swarms face significant challenges during dynamic target encirclement in complex marine environments, particularly regarding strong target maneuverability and strict safety constraints. To address these issues, this paper proposes a novel encircleme...

3D numerical study of race-tracking and air entrapment phenomena in polymer filling process

Abstract The race-tracking effect and air entrapment are two important phenomena that restrict the quality and performance of injection molded parts. This study considers two types of parts with different wall-thickness distributions. Through numerical simulations combined with e...

SDIM-YOLOv5: Real-Time Helmet Detection Method for Non-Motorised Vehicles Based on Improved YOLOv5

To effectively address the challenge of balancing detection accuracy and efficiency in helmet-wearing detection, this paper proposed an improved YOLOv5 framework called SDIM-YOLOv5. Firstly, the CSPDarknet53 in the YOLOv5s benchmark structure was replaced by SimRepCSP to reduce m...

Studying the tensor resonance contributions in $$B \rightarrow PP\ell ^+\ell ^-$$ and $$B \rightarrow PV\ell ^+\ell ^-$$ decays

Abstract We analyze the semileptonic $$B \rightarrow T\ell ^+\ell ^-$$ B → T ℓ + ℓ - , $$B \rightarrow T(\rightarrow PP)\ell ^+\ell ^-$$ B → T ( → P P ) ℓ + ℓ - , and $$B \rightarrow T(\rightarrow PV)\ell ^+\ell ^-$$ B → T ( → P V ) ℓ + ℓ - decays with $$\ell =e,\mu ,\tau $$ ℓ =...

Fused Triphenylamine‐Terminated Self‐Assembled Hole‐Transporting Monolayers for Perovskite Solar Cells

ABSTRACT Conventional self‐assembled hole‐transporting monolayers (SAMs) in perovskite solar cells (PSCs) suffer molecular aggregation, uneven coverage on rough FTO substrates, and insufficient interfacial defect passivation. The design and application of novel SAMs have become a...

Molecular Cloning, In Silico Characterization, and Promoter Analysis of a Putative ETHE1 Gene from Jatropha curcas

Sulfur metabolism and stress responses are fundamental to plant growth and seed development. ETHE1 encodes a mitochondrial sulfur dioxygenase that plays important roles in these processes; however, its function in Jatropha curcas remains unknown. In this study, we report the clon...

Self-Powered Triboelectric Biofluid Sensors for Early Disease Screening and Diagnosis: A Review

With the growing demand for continuous health assessment and early disease screening, biofluids have attracted increasing attention because they provide molecular information that cannot be obtained from conventional physical signals alone. However, practical biofluid analysis re...

Assessing China’s COVID-19 control measures: a quantitative analysis based on a SIRD model

Abstract This paper established a Susceptible-Infected-Recovered-Dead (SIRD) model to fit and predict the COVID-19 epidemic in China. On the premise of passing the Markov Chain Monte Carlo (MCMC) robustness check, we counterfactually assessed the effectiveness of partial unlockin...

Herb‐Based Chiral Nanomaterials: Potential Application in Wound Healing and Nanomedicine

The remarkable progress in nanomedicine has opened new frontiers in boosting therapeutic efficacy and reducing off-target side effects. However, fabricating chiral nanomaterials remains challenging due to difficulties in sustaining chiral configuration stability. In this study, c...

The interaction effect of prepared dishes brand image and product type on consumer purchase intention

Purpose As consumer motivations for purchasing prepared dishes shift from efficiency-driven to value-driven, marketers need to understand how strategic alignment between brand image and product type influences purchase decisions. This study aims to examine how matching brand imag...

Multi-Feature Fusion and Seasonal Selection for Forest Type Mapping in a Subtropical–Temperate Monsoon Climate Ecotone Using Sentinel-1/2: A Case Study

Fine-scale mapping of forest types is a prerequisite for accurately assessing forest biomass, biodiversity, ecosystem service values, and carbon budgets. Shihe County, located within an ecotone transitioning from subtropical to temperate monsoon climates in China, was selected as...
