The objectives of this study were to investigate the effectiveness of the Commissioning Course (CC) to develop and maintain standards of fitness, to assess capability to perform military tasks, and to determine the relationship between fitness and risk of injury in 106 British Army officer cadets (OCdts). Aerobic fitness, muscular strength, endurance, and body composition were regularly assessed. Performance on four representative military tasks was measured at the end of the CC. All injuries in term 1 were documented. Over the CC, changes in fitness were generally modest and equivocal. Aerobic fitness improved by approximately 10% (p < 0.01), strength by 5 to 9% (p < 0.05 to p < 0.01), and muscular endurance by 55% (p < 0.01). Reductions in fat (p < 0.01) and gains in fat free mass (p < 0.05) averaged 3%. The females demonstrated greater improvements than the males. The majority of OCdts passed the representative military tasks, although females in some trades showed high failure rates. Forty-six percent of OCdts sustained injuries in the first term, resulting in 5% of man-days lost. No gender difference was found in injury rates. The least aerobically fit OCdts sustained more injuries than their fitter counterparts. In conclusion, there is scope for optimizing the effectiveness of the CC to enhance fitness and improve the focus of physical training on maximizing military task performance.

Purpose: To assess physiological metrics during the use of a commercially available bilateral active ankle exoskeleton during a challenging military-relevant task and if use of the exoskeleton during this task influences: metabolic load, physiological measures or rate of perceived exertion.
Methods: Nine healthy volunteers (5M, 4F) completed this randomized cross-over design trial, with a baseline visit and two randomized test sessions (with/without the exoskeleton). Variables included impact on time to exhaustion during walking on a treadmill at varying speeds and gradients (0-15%) at 26.

Attention Deficit Hyperactivity Disorder (ADHD) is a highly prevalent neurodevelopmental disorder, affecting both children and adults, which often leads to significant difficulties with attention, impulsivity, and working memory. These challenges can impact various cognitive and perceptual domains, including music perception and performance. Despite these difficulties, individuals with ADHD frequently engage with music, and previous research has shown that music listening can serve as a means of increasing stimulation and self-regulation.

Flapping wing micro aerial vehicles (FWMAVs) are recognized for their significant potential in military and civilian applications, such as military reconnaissance, environmental monitoring, and disaster rescue. However, the lack of takeoff and landing capabilities, particularly in landing behavior, greatly limits their adaptability to the environment during tasks. In this paper, the purple stem beetle (), a natural flying insect, was chosen as the bionic research object.

Multi-agent systems often face challenges such as elevated communication demands, intricate interactions, and difficulties in transferability. To address the issues of complex information interaction and model scalability, we propose an innovative hierarchical graph attention actor-critic reinforcement learning method. This method naturally models the interactions within a multi-agent system as a graph, employing hierarchical graph attention to capture the complex cooperative and competitive relationships among agents, thereby enhancing their adaptability to dynamic environments.

Background: Spatial working memory is crucial for processing visual and spatial information, serving as a foundation for complex cognitive tasks. However, the effects of prolonged sleep deprivation on its dynamics and underlying neural mechanisms remain unclear. This study aims to investigate the specific trends and neural mechanisms underlying spatial working memory alterations during 36 h of acute sleep deprivation.
