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

Active Disturbance Rejection Flight Control and Simulation of Unmanned Quad Tilt Rotor eVTOL Based on Adaptive Neural Network

Drones
The unmanned quad tilt-rotor eVTOL (QTRV) is a variable-configuration aircraft that combines the features of vertical takeoff and landing (VTOL), hovering, and high-speed cruising, making its control system design particularly challenging.

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 ...
