Eosinophilic Oesophagitis Beyond the Oesophagus: High Prevalence of Chronic Rhinosinusitis‐Type Symptoms and Their Impact on Symptom Severity in Swiss EoE Cohort Study Patients

Alimentary Pharmacology &Therapeutics, Volume 64, Issue 7, Page 965-975, October 2026.
Among 211 prospectively followed Swiss patients with eosinophilic oesophagitis, chronic rhinosinusitis was two‐ to three‐fold more common than in the general population. It was associated with greater oesophageal symptom severity and, in a quarter of cases, was experienced by patients as more debilitating than the underlying oesophageal disease ...

Persistence without prosperity at the upper range margin: Elevation, microhabitat buffering and biotic pressure in a range‐expanding spider

Ecological Entomology, Volume 51, Issue 5, Page 926-943, October 2026.
Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

Efficacy of Painting Wind Turbine Blades as a Mitigation Measure to Reduce Bird Collisions in a Mediterranean Wind Farm

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Bird mortality due to collisions with wind turbines necessitates the implementation of measures to mitigate this impact. Blade patterning has shown to be a promising measure to increase turbine visibility to birds and reduce collisions. Employing a Before–After–Control–Impact experiment using long‐term fatality searches, bird fatality rates were ...

Interfacial Solvent Molecular Engineering via High‐Safety Dense Separators for High‐Rate Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
The dense PPS‐separator prevents thermal runaway by allowing electron transfer through the steel needle during penetration, while the residual electrolyte enables brief ion migration and Joule heating, causing rapid electrolyte vaporization, collapse of the ion transport network, and a sharp drop in ionic conductivity.

Classification and analysis of low probability of intercept radar signals using image processing [PDF]

, 2003
The characteristic of low probability of intercept (LPI) radar makes it difficult to intercept with conventional signal intelligence methods so new interception methods need to be devel-oped.

Deep Spatially Varying Coefficient Model for Interpolation of Non‐Stationary Meteorological Data

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT In spatial statistics, the spatially varying coefficient model (SVCM) is widely applied in the analysis and interpolation of non‐stationary spatial data. By incorporating spatially varying coefficients, the model can capture spatial heterogeneity and provide an attractive interpretation of response‐covariate associations.

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...

S-Band Low-Probability Intercept Radar Antenna With Low Sidelobe Level

Applied Computational Electromagnetics Society Journal (ACES)
A half-wave dipole array antenna design for S-band low probability of intercept (LPI) radar is presented. The antenna structure comprises 24×2 linearly polarized dipole elements. A 24-column Taylor distribution weighted feed in the azimuth plane realizes low sidelobe level (SLL) of −26.0 dB. The antenna achieves an operational bandwidth of 100 MHz with
