Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

Metastability of solitary roll wave solutions of the St. Venant equations with viscosity [PDF]

, 2010
We study by a combination of numerical and analytical Evans function techniques the stability of solitary wave solutions of the St. Venant equations for viscous shallow-water flow down an incline, and related models.

Structured Knowledge Representation for Image Retrieval

, 2011
We propose a structured approach to the problem of retrieval of images by content and present a description logic that has been devised for the semantic indexing and retrieval of images containing complex objects.

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

Biomechanics of predator–prey arms race in lion, zebra, cheetah and impala [PDF]

, 2018
The fastest and most manoeuvrable terrestrial animals are found in savannah habitats, where predators chase and capture running prey. Hunt outcome and success rate are critical to survival, so both predator and prey should evolve to be faster and/or more

Response to equine cardiac adverse events during sports

Equine Veterinary Education, EarlyView.
Summary Cardiac adverse events and sudden death are a feared scenario for equine veterinarians, with serious consequences for animal health, riders' safety and the social licence to operate equestrian sports. The response to equine cardiac adverse events (CAEs) during sports is poorly defined.

On the One-dimensional Stability of Viscous Strong Detonation Waves [PDF]

, 2003
Building on Evans function techniques developed to study the stability of viscous shocks, we examine the stability of viscous strong detonation wave solutions of the reacting Navier-Stokes equations.
