Of cables and threads

American Ethnologist, EarlyView.
Abstract Over the past two decades, gondola lifts have become central to interventions in urban Latin America's auto‐constructed peripheries. As cable car urbanism reshapes the city's edge, it raises fundamental questions about the notion of the “urban fabric” as a sociomaterial practice, an epistemology, and a site of politics.

Safer prehospital anaesthesia: updated guidelines from the Association of Anaesthetists

Anaesthesia, EarlyView.
Summary Introduction Prehospital emergency anaesthesia is recognised as a high‐risk clinical intervention. These updated guidelines consider changes in prehospital practice and parallel changes in the practice of in‐hospital emergency anaesthesia, with the aim of encouraging standardised safe anaesthetic practice in a challenging clinical area.

Research on Characteristics of Helicopter Engine Bleed Airflow Limitation and Temperature Drop

Nanjing Hangkong Hangtian Daxue Xuebao
The helicopter’s environmental control system is restricted from drawing more than its engine’s maximum allowed bleed air volume to avoid excessive power loss.

Navier-Stokes Prediction of the Effect of the Skids on the Aerodynamics of Helicopter Fuselage in Forward Flight

, 2006
A series of three-dimensional Navier-Stokes computations were carried out with and without skids to investigate the influence of the skids on the flow field and aerodynamic forces acting on a helicopter fuselage in low Mach number forward flight under ...

Two Decades of Evolution in Abdominal Trauma Surgery: Trends, Outcomes, and Implications From an Australian Level 1 Trauma Centre

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background Advances in imaging, non‐operative management, and endovascular techniques have reshaped abdominal trauma care, but their impact on operative trends in blunt‐dominant Australian trauma systems is incompletely described. Aims To describe temporal trends in operative and minimally invasive management of abdominal trauma at an ...

Mortality From Rural Traumatic Brain Injury Are Underestimated Without Inclusion of Prehospital Deaths

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background Rural residents are more likely to suffer moderate and severe traumatic brain injury (TBI) and experience delay to definitive care than urban patients. Prior studies comparing these populations were based on hospitalised patients only. We examined TBI outcomes incorporating pre‐hospital mortality to determine the association between

Effects of Leading Edge Radius on Stall Characteristics of Rotor Airfoil

Aerospace
The effects of leading edge radius on the static and dynamic stall characteristics of rotor airfoils are investigated. Initially, a parametric airfoil (PARFOIL) method is employed to generate four morphed airfoils with different leading edge radii based ...

SAGE: Structure‐Aware Generative Video Transitions between Diverse Clips

Computer Graphics Forum, EarlyView.
Abstract Video transitions aim to synthesize intermediate frames between two clips, but naïve approaches such as linear blending introduce artifacts that limit professional use or break temporal coherence. Traditional techniques (cross‐fades, morphing, frame interpolation) and recent generative inbetweening methods can produce high‐quality plausible ...
