Beyond the Single Pathogen Paradigm in Citrus: A Pathobiome Perspective on Disease Complexes, Microbiome Dysbiosis, and Management

Citrus diseases are commonly interpreted within a single pathogen framework, yet increasing evidence shows that disease outcomes can also be shaped by mixed infections, disease-associated microbiome restructuring, host responses, and interactions among multiple biotic agents. Thi...

Suppression of meiotic double-strand break formation in somatic cells by DREAM factors TCX5/6 maintains genome stability

Meiotic recombination in reproductive cells is initiated by DNA double-strand breaks (DSBs) and requires the expression of meiosis-specific genes, yet how the transcription of those genes is regulated in either meiotic or somatic cells remains unclear. Here, using a representativ...

Volatile-element depletion in rocky planets as a purity spectrum of a single information field: An information-dynamics reinterpretation of hybrid accretion

Wang et al. (2026, Nature Astronomy) showed that the moderately-volatile lithophile element (MVLE) depletion patterns of Earth and Mars record different formation pathways: Earth accreted ≳75% of its mass via pebble accretion, Mars ∼73% via collisions of volatile-depleted planete...

Dynamic fund protection in markets with stochastic volatility and frictions: a double Heston model with transaction costs and its applications

This paper develops a pricing framework for Dynamic Fund Protection (DFP) contracts with lookback features under a double Heston stochastic volatility model with proportional transaction costs. The valuation leads to a multidimensional nonlinear partial differential equation (PDE...

CAMM-Based Rational Hapten Design for Monoclonal Antibodies with Different Specificities against Avermectins and a Sensitive Chemiluminescence Immunoassay

Abstract Computer-aided molecular modeling (CAMM) has become an important tool for guiding rational hapten design. Avermectins are a family of macrocyclic lactones with highly similar structures, making monoclonal antibody (mAb) specificity difficult to control. In this work, we...

Polysiloxane Supramolecular Elastomers via Programmable Ionic-Hydrogen-Bonded Aggregates

Abstract While nanoscale aggregates as dynamic crosslinks enhance supramolecular elastomers, systematically elucidating how aggregate parameters are regulated and dictate mechanical responses remains challenging. Here, we fabricate polysiloxane-based supramolecular elastomers wit...

A Typological Analysis of Rural Youth Deliberative Participation and Its Generative Logic: A Case Study of D Village, H Province

Rural youth participation in deliberative consultation has the potential to revitalize grassroots good governance; however, insufficient participation remains a persistent challenge. Based on fieldwork in townships in North China, this qualitative study employs Coleman’s rational...

PK/PD Modeling of a Novel Pleuromutilin Derivative Pleuro2–4 against Mycoplasma gallisepticum in Chicks

Abstract Mycoplasma gallisepticum is a major causative agent of chronic respiratory disease in poultry, and effective antimicrobial therapy remains essential for disease control. In this study, the antimycoplasmal activity, pharmacokinetics, therapeutic efficacy, and pharmacokine...

Visual Symbols, the Consciousness of Daotong, and Sacrality: A Study of Wang Yangming’s Sage Portraits

Wang Yangming’s sage portraits functioned as material objects that transmitted Confucian orthodoxy (daotong 道統) and constructed sacrality through visual symbols, inscriptional texts, and ritual deployment. Drawing on material culture studies, this article examines the typologic...

Urban Segregation and Migrant Overwork: Evidence From Hukou Conversion in China

ABSTRACT This paper develops a simple theoretical model to examine the impact of urban segregation, driven by the hukou system, on labor supply, with a specific focus on overwork among rural‐to‐urban migrants in China. Using data from the 2017 Urban–Rural Comparative Survey, we a...

Reconfiguring Rubberwood Starch from a Weak Link to a Protective Shield against Decay and Mold

Abstract Starch has long been regarded as a critical weakness limiting rubberwood’s construction applications due to its hygroscopicity and mold susceptibility. Instead of removing or chemically modifying this component, we develop a green hydrothermal and controlled drying strat...

Biochar–Microbe Interactions for Co-Remediation of Heavy Metals and Pesticides in Soils: Mechanisms, Synergies, and a Translational Framework

The co-occurrence of heavy metals (HM) and pesticides (PS) in agricultural soils poses a complex remediation challenge that resists single-amendment strategies. Although biochar (BC) has been widely reported as an efficient adsorbent for specific contaminants, increasing evidence...

The RpfF Acyl-ACP thioesterase of major rice pathogen Xanthomonas oryzae pv. oryzae is essential for maintenance of membrane function and virulence

In Xanthomonas , RpfF is a bifunctional enzyme having both enoyl-ACP dehydratase and acyl-ACP thioesterase activities catalyzed by a single active site. While the hydratase activity is essential for producing quorum-sensing signals of the diffusible signal factor (DSF) family, th...

DWEC-YOLO: A Multi-Behavior Detection Model for Group-Housed Pigs

In large-scale pig farming systems, high visual similarity among pigs, complex posture variations, and frequent interactions between individuals pose significant challenges to vision-based multi-behavior detection. To overcome these limitations, this study proposes an improved YO...

Non-Target Arthropod Community Variation Associated with Abamectin Trunk-Injection History in a Pinus massoniana Plantation

Abamectin trunk injection is used to control pine wilt disease, but field evidence linking injection history to non-target arthropod communities is limited. We compared uninjected plots with plots injected once in March 2024 (ATI1) or March 2022 (ATI3) in a Pinus massoniana plant...

Knockout of odourant receptor co-receptor HvarOrco compromises reproductive fitness in the ladybird Hippodamia variegata

Abstract The predatory ladybird, Hippodamia variegata , relies critically on olfaction for host location, oviposition site selection, and predator avoidance. Here, we employed CRISPR/Cas9-mediated genome editing to generate a stable, heritable odourant receptor co-receptor ( Orco...

Preharvest CPPU Application Improves Litchi Fruit Storability via Modification of Hormone Profiles and Maintenance of Recalcitrant Seed Vigor

Litchi (Litchi chinensis Sonn.), an important fruit in south China, rapidly loses commercial value within 3–4 days at ambient temperatures due to poor storability. Previous studies have shown that 5 mg L−1 CPPU (N-(2-chloro-4-pyridyl)-N′-phenylurea) application can improve postha...

Moralizing markets for farmland protection: urban-rural solidarity through responsible consumption in Guangdong, China

How are moralized markets made, and by whom? Research on ethical consumption and alternative food networks generally locates the moral qualities of markets in grassroots activism, social movements, or producer–consumer cooperation, while public authorities appear as regulators or...

A Copula-based composite drought index for vegetation and hydrological droughts

Drought is a complex natural hazard with profound impacts on vegetation and water resources. However, existing monitoring approaches often treat vegetation and hydrological droughts separately, limiting a comprehensive understanding of their interactions. To address this gap, thi...

County-Level Rice Yield Estimation in Guangdong Province, China, Using a Prior-Guided Environmental Fusion Network

Accurate county-level rice yield estimation is important for regional production monitoring, yet dense field-level observations are often unavailable and prediction across unseen years remains challenging. This study involved the development of a prior-guided environmental fusion...
