Plant viruses convergently target NPR1 with various strategies to suppress salicylic acid‐mediated antiviral immunity

open access: yesJournal of Integrative Plant Biology, EarlyView.
Viral infection triggers monomerization and nuclear translocation of the salicylic acid receptor NONEXPRESSOR OF PATHOGENESIS‐RELATED GENES1 (NPR1) to activate pathogenesis‐related gene expression. Nevertheless, viruses have developed one or more proteins to target NPR1 and impair its functionality through mechanisms such as inducing its degradation ...

(n-2)-tightness and curvature of submanifolds with boundary

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
The purpose of this note is to establish a connection between the notion of (n−2)-tightness in the sense of N.H. Kuiper and T.F. Banchoff and the total absolute curvature of compact submanifolds-with-boundary of even dimension in Euclidean space.

Integrable lambda models and Chern-Simons theories

open access: yesJournal of High Energy Physics, 2017
In this note we reveal a connection between the phase space of lambda models on S 1 × ℝ $$ {S}^1\times \mathbb{R} $$ and the phase space of double Chern-Simons theories on D × ℝ $$ D\times \mathbb{R} $$ and explain in the process the origin of the non ...

Supersymmetry and superstrata in three dimensions

open access: yesJournal of High Energy Physics, 2021
We analyze the supersymmetry transformations of gauged SO(4) supergravity coupled to extra hypermultiplets in three dimensions, and find large families of smooth BPS solutions that preserve four supersymmetries.

Parasitic success of the pathogenic plant Phelipanche ramosa (L.) Pomel. (Orobanchaceae) differs in some re‐infected versus naïve tomato cultivars

open access: yesWeed Research, EarlyView.
Abstract Plants are exposed to infection and predation by organisms from most kingdoms of life, including their own. Layers of molecular defence mechanisms have evolved to limit damage and disease from microbial and insect pathogens, and plants can also defend themselves against attack by members of their own kingdom.

Mapping Corporate Investments Between China and Europe in an Era of Geoeconomic Competition

open access: yesJCMS: Journal of Common Market Studies, Volume 63, Issue 3, Page 932-963, May 2025.
Abstract The consolidation of geoeconomic competition puts core aspects of global economic interdependence, such as the mutual China‐EU investment relationship, under increased pressure. Headlines about ‘derisking’, ‘decoupling’ or ‘deglobalization’ dominate current debates but tend to be overly simplistic.

Quantum Geometric Moment Encodes Stacking Order of Moiré Matter

open access: yesAdvanced Materials, Volume 37, Issue 15, April 16, 2025.
The Berry curvature dipole (BCD) changes across valley Chern transitions. A new electrical technique is developed to use such BCD sign flips for distinguishing the stacking order of a moiré material, namely twisted double bilayer graphene. Such a method, analogous to spectroscopic techniques, establishes a link between quantum geometry and stacking ...

Algorithmic Competency of On‐Demand Labor Platform Workers: Scale Development, Antecedents, and Consequences

open access: yesAsia Pacific Journal of Human Resources, Volume 63, Issue 2, April 2025.
ABSTRACT Despite the highly controlled algorithmic work environment, on‐demand labor platform workers may devise strategies to enhance their algorithmic competency (AC), facilitating better adaptation to the system. Yet, the proactive engagement of platform workers with algorithms remains underexplored in empirical research.

The Intertidal North‐South Split: Oceanographic Features and Life History Shape the Phylogeography of Chiton Acanthochitona rubrolineata

open access: yesEvolutionary Applications, Volume 18, Issue 4, April 2025.
ABSTRACT The genetic structure and demographic history of marine organisms are shaped by a variety of factors including biological and ecological characteristics, ocean currents, and the palaeogeological effects of sea‐level fluctuations. Here we present a comprehensive method combining population genomics, laboratory experiments, and ocean modelling ...

A machine vision‐based intelligent segmentation method for dam underwater cracks using swarm optimization algorithm and deep learning

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 10, Page 1405-1417, 18 April 2025.
Abstract Ensuring the safety of water networks is a research hotspot in the current water conservancy industry, and dams are an important part. However, over time, the dam is prone to varying degrees of aging and disease, most of which are structural cracks.
