Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Improving Thermal Transport in Carbon Nanotube Films Through Interface and Structural Optimization

Carbon and Hydrogen, EarlyView.
Using over 400 nonequilibrium molecular dynamics simulations, the effects of CNT alignment, density, tube length, and interfacial thermal resistance on heat transport in carbon nanotube films were investigated. Interfacial thermal resistance was identified as the primary performance‐limiting factor, whereas improved alignment increased the thermal ...

Preventing wall deposition in duct flows: The role of particle number density and flow direction

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Particle deposition in wall‐bounded turbulent flows is a challenge in many industries, including pneumatic conveying, filtration, and related applications. When particles accumulate near boundaries, they reduce transport efficiency, alter near‐wall flow structures, and cause blockage.

Prevention of Work‐Related Musculoskeletal Disorders and Career Sustainability in Head and Neck Reconstructive Surgery: Integrating Ergonomics and Physical Conditioning

Head &Neck, EarlyView.
ABSTRACT Background Head and neck reconstructive and plastic surgery exposes surgeons to prolonged static posture, sustained visualization of a narrow operative field, cervical and shoulder loading, fine‐motor work, and extended standing. These demands create a substantial occupational musculoskeletal burden.

Overcoming spectral limits of perovskite photodetectors for the infrared region

InfoScience, EarlyView.
Infrared (IR) photodetectors are vital for modern optoelectronics, but traditional inorganic semiconductors face limitations in cost, processing, and bandgap tunability. This review provides a summary of advanced strategies to extend metal halide perovskites into the IR region, categorizing approaches into intrinsic material engineering, physical ...

Diffusion MRI‐Based Fetal Thermometry Using Cerebrospinal Fluid: A Translational Feasibility Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Noninvasive fetal temperature assessment could improve MRI safety monitoring and provide insight into fetal physiology. Diffusion MRI is a potential approach because water diffusivity in free fluids is temperature dependent. However, the applicability of adult‐derived diffusivity–temperature calibration to neonatal and fetal CSF ...

Stretch‐shortening cycle force–time and power–time waveform analysis indicates limitations of the contralateral limb benchmark in athletes with ACL injury

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Unilateral countermovement jump (CMJsingle) testing is commonly used after anterior cruciate ligament reconstruction (ACLR) to assess stretch‐shortening cycle (SSC) function and return‐to‐sport readiness. However, the impact of ACLR on contralateral limb SSC function is poorly understood, which may impact the utility of the ...

Detection of previous knee injuries using lower limb‐worn inertial measurement units: A cross‐sectional machine‐learning study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Previous knee injury increases the risk of subsequent injury, even after functional recovery, yet residual gait, running or load alterations often go undetected in routine assessment. Wearable inertial measurement units (IMUs) may enable scalable detection of such alterations outside laboratory settings.
