Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

CLINICO–Demographic Profile and Outcomes of Hospitalised Children With Diphtheria in A Tertiary Care Hospital of Peshawar

Acta Paediatrica, EarlyView.
ABSTRACT Aim To determine the clinico‐demographic profile and predictors of mortality in hospitalised children with diphtheria. Methods This retrospective cohort study included 202 children aged 5–16 years diagnosed with diphtheria per WHO criteria at Lady Reading Hospital, Peshawar, from January 2023 to December 2024. Data on demographics, vaccination

Human Disturbance but Not Predation Risk Is Associated With Increased Vigilance in Roe Deer

Ethology, EarlyView.
Roe deer vigilance is lower in natural than in modified habitats, decreases with group size, but is not significantly influenced by stable wolf presence, suggesting habitat‐driven risk perception and reliance on spatial avoidance over increased alertness.

The hypothalamic-pituitary-adrenal axis in anxiety and panic [PDF]

, 2010
This review article focuses on the differential activation of the hypothalamic-pituitary-adrenal (HPA) axis in generalized anxiety and panic. The results of experimental studies that assayed adrenocorticotropic hormone, cortisol and prolactin show that ...

The use of exercise testing to assess training efficacy in sport horses

Equine Veterinary Education, EarlyView.
Summary Training programmes for horses must be tailored to the physiological demands of each Fédération Équestre Internationale (FEI) discipline to optimise performance and welfare. Standardised exercise tests (SETs) have emerged as essential tools for evaluating equine fitness by measuring physiological responses to controlled workloads.

Air embolism secondary to suspected lymphatic tissue disruption with severe exercise‐induced pulmonary haemorrhage

Equine Veterinary Education, EarlyView.
Summary Air embolism is rare in horses and typically associated with complications following intravenous catheterisation or other medical procedures. Exercise‐induced pulmonary haemorrhage (EIPH) is common in racehorses but not usually associated with air embolism. This report describes a case of air embolism in a 4‐year‐old Thoroughbred with EIPH. The

Turf track surface interaction with speed and musculoskeletal injury risk in Thoroughbred racehorses

Equine Veterinary Journal, EarlyView.
Abstract Background Injury modelling based on changes in speed and stride characteristics of racehorses has become a primary industry focus for the Thoroughbred racing industry. However, speed and stride characteristics are strongly associated with track condition; therefore, reliable quantification of surface variables for use in future models is ...

A longitudinal study of radiodensity and radiographic appearance of the proximal sesamoid bones in Thoroughbred racehorses

Equine Veterinary Journal, EarlyView.
Abstract Background There are limited data on long‐term follow‐up of radiographic changes of the proximal sesamoid bones (PSBs) in Thoroughbred racehorses. The effect of training and racing on radiodensity of the PSBs in live Thoroughbreds has not been described.

Theory of weakly nonlinear self sustained detonations

, 2014
We propose a theory of weakly nonlinear multi-dimensional self sustained detonations based on asymptotic analysis of the reactive compressible Navier-Stokes equations.

Efficient numerical stability analysis of detonation waves in ZND

, 2010
As described in the classic works of Lee--Stewart and Short--Stewart, the numerical evaluation of linear stability of planar detonation waves is a computationally intensive problem of considerable interest in applications. Reexamining this problem from a
