Research on Multi-Point large strain measurement sensors based on flexible thin Films and fiber Bragg Gratings

To achieve highly sensitive distributed measurement of large strains, this paper proposes a surface-attached FBG array sensor based on a flexible PDMS/SiO 2 substrate. The sensor structure is designed, and a finite element model of the flexible thin-film substrate and the S-shape...

The exact maximum growth factor for complete pivoting on real 5 × 5 matrices

Abstract Let ρ₅ᴿ be the largest element growth possible in exact Gaussian elimination with complete pivoting on real 5 × 5 matrices, with every legal choice at a pivot tie allowed. We prove ρ₅ᴿ = α = 4.132517078632472854223346853277…, where α is the algebraic lower bound identifi...

High‐Performance Broadband Infrared Photodetector Based on a VOPc/1T'‐MoTe 2 /Ultra‐Thin SiO 2 /Si Double Heterojunction

ABSTRACT Silicon‐based photodetectors integrated with two‐dimensional (2D) materials are promising for broadband photodetection, yet simultaneously achieving high responsivity, fast response, and broadband near‐infrared (NIR) detection remains challenging. Herein, we demonstrate...

Solution‐Processed Sandwich‐Structured Organic Photovoltaics

Current organic photovoltaic (OPV) devices still rely on complex multilayer architectures, which inevitably increase OPV production costs. Here, we propose a simple sandwich‐structured OPV device composed solely of a bottom electrode/active layer/top electrode configuration, with...

Numerical Study of Dual Lateral-Jet Interactions in Reaction Control Systems Under High-Speed Rarefied Flow Conditions

Reaction control systems (RCSs) provide rapid and effective attitude-control capabilities for high-speed vehicles operating in high-altitude, low-density environments, where conventional aerodynamic control surfaces become inefficient. However, interactions between lateral jets a...

Environmental heterogeneity shapes divergent assembly processes and network stability of plankton communities along a tropical island coast: Evidence from Hainan Island

Understanding how plankton communities respond to environmental heterogeneity is essential for assessing tropical island coastal ecosystems and supporting region-specific management. Based on data from 59 environmental monitoring stations, including 16 stations with plankton samp...

GNSS monitoring and stability evolution mechanism of the S-J1 deformation body in the lower reaches of the Jinsha River

Catastrophic landslides triggered by reservoir impoundment represent one of the most destructive geohazards in the field of hydropower engineering, posing significant threats to human lives, property, and the long-term operational safety of critical infrastructure. A large hydrop...

Seamless grid following and grid forming inverter mode transition enabled by machine-learning based SCR estimation and smooth switching control

The increasing penetration of inverter-based resources has led to converter-dominated power systems in which grid strength varies significantly and strongly influences inverter control performance. Grid-following (GFL) and grid-forming (GFM) control strategies offer complementary...

Prediction of Joint Roughness Coefficient Using Metaheuristic-Optimized Random Forest Model

Reliable estimation of the joint roughness coefficient (JRC) is important for quantitative characterization of joint roughness and provides an important geometric parameter for subsequent joint shear strength assessment. However, single-parameter empirical models cannot fully cap...

Conserved nuclear receptor antagonism balances Hippo and Notch to control tissue growth and tumor suppression

Nuclear receptors orchestrate diverse biological processes through ligand-dependent transcriptional control, yet how competing family members balance oncogenic signaling to maintain tissue homeostasis remains poorly understood. Here, we uncover an evolutionarily conserved antagon...

Increasing Global Burden of Inflammatory Bowel Disease and Its Attributable Anemia in Adults Aged 60 Years and Older: A Comprehensive Analysis of the Global Burden of Disease Study 2021

OBJECTIVE: To quantify the global burden of inflammatory bowel disease (IBD) and IBD-attributable anemia in adults aged ≥ 60 years across 204 countries and territories from 1990 to 2021 and their projected trends through 2045 based on the Global Burden of Disease (GBD) 2021 datab...

A Scale-Adaptive Framework for Building Generalization via Instruction-Guided Diffusion and Geometry-Aware Vectorization

Abstract Map generalization aims to adapt detailed geospatial data to visualization at different map scales while preserving legibility and geometric consistency. Recent learning-based approaches have shown promising results, but they typically require training separate models fo...

Methyl indole-3-acetate contributes to strain-specific anti-inflammatory effects of Lactiplantibacillus plantarum

Lactiplantibacillus plantarum is a widely recognized probiotic with anti-inflammatory potential, yet its efficacy varies among strains and the underlying determinants remain poorly defined. Here, we identify methyl indole-3-acetate (MIA), a previously uncharacterized microbial me...

5C psychological antecedents of vaccine hesitancy toward maternal RSV vaccines and infant monoclonal antibodies among pregnant and postpartum women and their partners in China: A multicenter, dyadic survey design, cross-sectional study

We assessed vaccine hesitancy toward two novel respiratory syncytial virus (RSV) immunization strategies, maternal vaccines and infant monoclonal antibodies (mAbs), among 4422 couples across eight Chinese provinces, via a multicenter cross-sectional survey with convenience sampli...

Box dimension of the graphs of recurrent fractal interpolation functions

Abstract Let f be a generalized affine recurrent fractal interpolation function with vertical scaling functions. In this paper, by introducing underlying local iterated function systems of f , we define restricted vertical scaling matrices. Then we analyze the irreducibility and...

Molecular Riveting Stabilizes Wide‐Bandgap Perovskites by Reinforcing Cation‐Octahedron Coupling

ABSTRACT High‐quality wide‐bandgap (WBG) perovskites are essential top‐cell absorbers for perovskite/silicon tandem cells, yet their stability is limited by light‐induced halide phase segregation and defect evolution. Here, we report a molecular riveting strategy that reinforces...

Potential Mechanisms Linking Excessive Testosterone to PMOS: Insights from Network Toxicology and Machine Learning
