Trait-level somatic anxiety modulates functional magnetic resonance imaging (fMRI) neural synchrony to naturalistic stimuli.

Somatic anxiety refers to the tendency to appraise situations as threatening, leading to heightened physiological arousal. Symptoms associated with higher levels of somatic anxiety that reflect autonomic arousal and perceptions of threat include elevated heartbeat perception, difficulty breathing, and palpitation. Somatic anxiety is generally associated with increased stimulus-driven attention; however, it is currently unknown how somatic anxiety modulates neural synchrony, measured by intersubject correlations (ISC), in response to complex audiovisual stimuli.

Preparticipation and Sideline Evaluation of Athletes with Intellectual and Developmental Disability.

Individuals with intellectual and developmental disability face several barriers to participation in sports and physical activity. Fortunately, there are opportunities for athletes with intellectual and developmental disability to participate in sport. Special Olympics continues to be the most prominent opportunity.

Tele-Ultrasound in the Wilderness: A Tutorial Experience for Medical Students.

Introduction: Providers can evaluate patients who sustain trauma during outdoor activities by using the extended focused assessment with sonography for trauma (FAST) and the limited knee ultrasound. Remote tele-mentored ultrasound (RTMUS) can help minimally trained providers in the wilderness if they have difficulty obtaining a view or have questions about the interpretation of an image. The goal of our study was to determine the feasibility of using RTMUS to teach the FAST exam and knee ultrasound exam to ultrasound-naive medical students during a wilderness medicine outdoor activity.

Azobenzene-Functionalized Semicrystalline Liquid Crystal Elastomer Springs for Underwater Soft Robotic Actuators.

As actuated devices become smaller and more complex, there is a need for smart materials and structures that directly function as complete mechanical units without an external power supply. The strategy uses light-powered, twisted, and coiled azobenzene-functionalized semicrystalline liquid crystal elastomer (AC-LCE) springs. This twisting and coiling, which has previously been used for only thermally, electrochemically, or absorption-powered muscles, maximizes uniaxial and radial actuation.
