Exogenous application of salicylic acid enhances seed germination in Apocynum venetum under salinity conditions

Abstract Salinity stress significantly impairs seed germination and seedling establishment in many economically valuable plant species. Salicylic acid (SA) is a key signaling molecule implicated in plant stress responses. However, a significant knowledge gap remains regarding its...

Bifurcation and hydra effect of a plant-herbivore model with herbivore harvesting

Adaptive management of herbivore populations during grassland plant degradation serves as a critical strategy for sustaining ecosystem stability. To address this imperative, establishing a mechanistic grassland resourceherbivore model that incorporates herbivore harvesting and ri...

Chiral Alanine Functionalized Perylene Diimides: Supramolecular Self-Assembly and Optical Properties

Water-soluble alanine-functionalized perylene diimide derivatives (PDI-Ala) were synthesized by introducing alanine units at the imide positions of the PDI framework. Their photoluminescence properties and supramolecular aggregation behavior were investigated in solvents of varyi...

Squeezing Enhanced Two Phase Estimation With N Particle W States

ABSTRACT Simultaneous estimation of two optical phases in a three‐mode interferometer assisted by optical parametric amplification (OPA) is investigated. The normally ordered characteristic function formalism is employed to derive analytical expressions for all photon number mome...

Research on music audio chord feature extraction and similarity calculation based on transformer and deep metric learning

Aiming at the problem that existing methods have difficulty balancing chord recognition accuracy and feature discrimination, this paper proposes the Transformer Chord Metric Extractor (TCME). The model effectively captures the long-range harmony dependence of music by designing a...
