Deterrence, Development, and Denial: Securitising Climate‐Induced Mobility in the European Union
ABSTRACT Climate‐induced mobility poses a mounting governance challenge for the European Union (EU), where climate action, migration control, and security policy intersect in uneven and contested ways. While EU discourse frequently frames climate change as a “threat multiplier,” migration governance remains anchored in deterrence logics, producing a ...

Multi-UAV Bearing-Only Active Tracking via Prescribed-Shell Bearing-Geometry Self-Organization
In multi-UAV bearing-only active tracking, the estimation and control performance is fundamentally determined by the target-centered bearing geometry, as passive angle-of-arrival measurements provide directional information without direct range ...

Search and Passage Are Decoupled for Migrating Trout Kelts at Multi‐Exit Dam
ABSTRACT Longitudinal and lateral river connectivity have been drastically reduced over time, with hydropower development as a major driver of fragmentation. While fishways are widely implemented to support upstream migration, downstream passage remains a major challenge.

ABSTRACT This study investigates how ordinary Taiwanese netizens perform linguistic authority by policing others’ use of Mainland Chinese expressions in everyday online interactions not originally intended to be political and how such policing is subsequently supported, resisted, or (de)legitimized in the context of Taiwan–China relations.

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Merged Interplanetary Data From L1: MIDL
Abstract The availability and accuracy of upstream solar wind conditions are critical for solar wind—magnetosphere coupling studies, whether based on observations or numerical models and simulations. We present the Merged Interplanetary Data from L1 (MIDL), which merges 1‐min magnetic field and plasma observations from ACE, DSCOVR, and Wind through a ...

Pre‐Existing Plasmaspheric Density Structure
Abstract We perform a basic model experiment: we run two nearly identical plasmapause simulations, differing only by their initial conditions. The first run contains initial fine‐scale and mesoscale structure, and the second run is initialized with a featureless, circular plasmapause.

Standoff Target Tracking Guidance using Line-of-Sight Distance Bifurcation
Unmanned aerial vehicle (UAV) applications that continue to receive significant attention are target acquisition and tracking. There exist many paths to track a stationary target from a prescribed altitude.

Self‐Adhesive Conductive Elastomers for Gel‐Free Biopotential Recording
σPOMaC, a self‐adhesive conductive citrate elastomer incorporating PEDOT:PSS and DBSA, enables gel‐free biopotential electrodes with stable conductivity and intrinsic skin adhesion. The composite exhibits low resistivity (∼ 0.02 Ω·cm), robust electrical performance during repeated use, and reliable on‐body ECG acquisition comparable to Ag/AgCl ...

Abstract Lunar magnetic anomalies are abundant near the south pole, where several moderate‐strength anomalies spatially overlap permanently shadowed regions (PSRs). This environment provides a unique setting to assess how crustal magnetic fields and topography regulate plasma–surface interactions and, in turn, the stability and distribution of surface ...
