Investigation of Position-Dependent Signal Propagation Delay in Large-Pitch AC-LGAD Using a Two-Dimensional Transmission-Line Model

This paper presents a study of position-dependent signal propagation delay in large-pitch pixelated AC-coupled Low-Gain Avalanche Detectors (AC-LGADs). In AC-LGADs, a continuous resistive N+ layer and segmented AC-coupled readout electrodes enable charge sharing and simultaneous...

Shut Your Eyes in the Dark! Differential Effects of Pre-Bedtime and Pre-Shuteye Media Use on Sleep Delay and Anxiety

The pervasive use of digital media before sleep is increasingly recognized as a critical factor affecting sleep and psychological well-being. However, the impact of bedtime media at different stages-specifically, before bedtime and before shuteye-remains unclear. Using data from...

Motivating executives for the long run: executive compensation stickiness, long-term focus and the radicalness of corporate innovation

Purpose Radical innovation is crucial for the long-term survival of firms, yet it remains challenging to achieve for most firms. To validate the theoretical rationale of executive compensation stickiness and link managerial cognition to corporate innovation, this study draws on t...

Natural Product Toosendanin Suppresses the Malignant Development of Skin Melanoma by Targeting BNC2 for Degradation

ABSTRACT Toosendanin (TSN) is a highly potent natural anticancer compound derived from the fruit of Fructus Meliae Toosendan. In this study, TSN inhibited melanoma cell proliferation and cell‐cycle progression, induced apoptosis, and suppressed metastasis in both in vitro and in...

Intratubular light chain amyloidosis: a comprehensive analysis of disease spectrum and clinicopathological characteristics

Abstract Background The disease spectrum of intratubular light chain amyloidosis (AL) remains unkown. Methods Patients with intratubular AL from a single center were retrospectively analyzed and stratified into 3 groups: Group 1, complicated by extra-tubular amyloidosis; Group 2,...

Multi-omics integration reveals human placental molecular signatures associated with microplastics exposure

Abstract Background Microplastics (MPs) are pervasive environmental contaminants that have been increasingly detected in human tissues. However, their molecular effects on the human placenta, a critical interface for maternal–fetal exchange and fetal development, remain poorly un...

Severity-dependent alterations in oral microbiota and antibiotic resistance in children with dental fluorosis

Backgroud Dental fluorosis is a prevalent endemic condition, yet its impact on the oral microbiota structure and resistance in children remains understudied.Objective To assess the microbial composition, diversity, functional pathways and co-occurrence patterns among urinary fluo...

Cumulative spatial assessment of observed wildlife-vehicle collisions based on indicator species thresholds

Global road network expansion has exacerbated wildlife-vehicle collisions. However, traditional risk assessments predominantly assume a linear relationship between landscape features and observed collision quantities, overlooking the non-linear threshold characteristics of ecolog...

Leveraging Self-Paced Learning for Software Vulnerability Detection

Vulnerabilities are major risks to software systems. Researchers have proposed many deep learning approaches to detect software vulnerabilities. However, their accuracy is limited in practice. One of the main causes is low-quality samples ( i . e ., source code and its label) in...

Understanding the Research Needs and Educational Methods of Surgeons to Help Guide Future Spine Deformity Research: A Survey of AO Spine Members

Study Design Cross-sectional survey. Objective Outcomes research has significantly shaped patient management in spine deformity care, while the dissemination of research remains a challenge. To guide future research directions, this study surveyed AO Spine members to identify the...

Unveiling non-Hermitian band structures with non-Bloch supercells

Abstract Real-valued band structures underpin the analysis of periodic Hermitian systems and are well established experimentally. By contrast, non-Hermitian systems feature complex band structures, in which energy and momentum acquire imaginary parts, enabling phenomena that defy...

Magma-induced midcrustal flow and high-temperature metamorphism: Insights from the early Mesozoic Yunkai massif (South China) and tectonic implications

The way in which partial melting weakens the middle continental crust and triggers lateral flow is fundamental to understanding orogenic processes, yet the specific roles of magmatic heat and deformation remain debated. We addressed this issue through an integrated study of the e...

Improved representation of isoprene-derived secondary organic aerosol in CAM6-Chem reveals regional contrasts in its long-term changes over China

Abstract. Isoprene-derived secondary organic aerosol (ISOA) is an important component of atmospheric organic aerosol, but its formation remains incompletely represented in global chemical models, creating uncertainty in ISOA changes and their drivers. In this study, we updated th...

Chemosymbiotic trophic strategy in an Ediacaran tubular animal

Chemosymbiosis may have been a key driver of early animal evolution and diversification. Yet evidence for animal–microbe nutritional partnerships in the fossil record of early metazoans remains scarce, largely owing to the limited availability of robust geochemical proxies and su...

The Impact of Urbanization on Tropical Cyclone Rainfall Over Complex Coastal Terrain

Abstract Rapid coastal urbanization alters land–atmosphere interactions and can modify tropical cyclone (TC) rainfall. This study examines urbanization effects on TC rainfall in the Yongjiang River basin, China, using the Weather Research and Forecasting model. Two TCs (Lekima 20...

Low-gas-flow strategy boosts hierarchical porosity of ZIF-8 single-atom catalysts for efficient adsorption-driven degradation

Hierarchical porosity amplifies single-atom catalyst (SAC) performance by enhancing mass transport and site accessibility, yet conventional fabrication typically relies on sacrificial-templating or post-etching protocols. Here, we construct well-connected pore networks via minima...
