Tail-Accuracy Degradation and Optimal Block Length for Block Self-Normalized Quantile Empirical Saddlepoint Inference under Dependence

Self-normalization combined with empirical saddlepoint approximation reaches higher-order tail accuracy under independent sampling, but under dependence the degradation is unquantified and the block length lacks a basis. This paper quantifies both for the block self-normalized qu...

YOLO-CCG: An enhanced model for weed detection in complex cotton fields

Accurate weed detection is essential for site-specific herbicide application in cotton production. However, variations in weed appearance, complex field backgrounds, uneven target distributions, and leaf occlusion can result in missed detections and false positives. To address th...

Closing the opportunity gap: Exploring micro-enterprises' behavioral intention to integrate with digital platforms for a broader agri-food system

Digital agriculture platforms offer marginalized micro-enterprises a vital pathway to bridge the opportunity gap and overcome structural dependencies on focal companies. However, mainstream literature's focal-firm bias leaves the adoption logic of these grassroots operators under...

Interfacial Failure Cascade and Modulation Strategies for Layered Oxide Cathodes in Sodium-Ion Batteries

Layered transition-metal oxides (NaxTMO2) are among the most promising cathode candidates for sodium-ion batteries, yet their interfacial degradation under high voltage, deep desodiation, and humid environments remains the central bottleneck to commercialization. Here we argue th...

Phase transition in new macroscopic continuum model considering forward–backward looking information and electronic throttle angle dynamics under overtaking effect

In the context of Connected Automated Vehicles (CAVs), overtaking behavior is a key factor leading to traffic instability. In real-world traffic scenario, driving decisions depend not only on forward-looking information but also on rear-view effects and vehicle dynamic control pa...

A collaborative perception framework for green jujube: from lightweight key point detection to posture-aware harvest analysis

Abstract Automated harvesting is pivotal to smart agriculture, yet precisely localizing picking points in complex orchard environments remains a key challenge for robotic harvesting systems. To this end, this study proposes a collaborative perception framework integrating a light...

Energy-Transfer Pathways in Nd-Sensitized Er-Rich Nanostructures: The Competition between Cross-Relaxation and Phonon-Assisted Sensitization

Abstract Rare earth-doped upconversion nanomaterials, which convert near-infrared light into visible or ultraviolet light, are widely recognized as having a huge potential application market, which unfortunately is restricted by their obstinate insufficient luminescence efficienc...
