Sex differences in physical performance, sleep, and psychological responses to long‐term, arduous military training

Physiological Reports, Volume 14, Issue 10, May 2026.
Abstract The U.S. Army Ranger Training Course (RTC) challenges candidates physically and mentally over 61+ days across varied environments. Psychological measures of resilience, grit, sleep, and physical performance have been investigated during RTC; however, whether those associations differ between sexes has not, despite sex integration occurring in ...

Energy efficiency of ship propulsive systems: rudder-propeller interaction

, 2010
The rudder of a ship is used to maintain its direction and for changing course. As such the goal of rudder design is to maximise sideforce for control of course while minimising resistive drag.

Decadal shifts in hypoxia and acidification reveal changing anthropogenic pressures on bottom waters of a coastal shelf

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Coastal systems provide habitat that sustains valuable shellfisheries but are subject to dissolved oxygen (DO) and/or carbonate chemistry impairment from anthropogenic pressures such as eutrophication and increasingly, climate change. Although extreme events can have disproportional negative ecological impacts, their ephemeral nature and a ...

Improving Power Generation in Rigid‐Wing Groundgen Airborne Wind Energy Systems Using Feedback Control—A Parametric Study

Wind Energy, Volume 29, Issue 4, April 2026.
ABSTRACT This paper explores different reel‐out strategies in a simulated environment to improve the power generation capability of Kitemill's KM1 prototype. The KM1 is a rigid‐wing groundgen airborne wind energy system that flies in circular loops during its power production phase. Firstly, we investigate the impact of flight and ground winch control.

Analysis of the Cavitating Flow Around the Horn-type Rudder in the Race of a Propeller

, 2001
This paper describes numerical methods by a mixed formulation of the boundary value problem (BVP) for the prediction of the cavitating flow around the horn-type rudder working behind a propeller.

Numerical and experimental study on flutter characteristics of a wing with drag rudder

Kongqi donglixue xuebao
The drag rudder serves as an unconventional control surface specifically designed for flying wing aircraft. Positioned near the wingtips, the drag rudder splits to generate drag force and yawing moments, which exhibits significant nonlinear ...
