MRI‐based quantification of whole‐organ renal metabolic rate of oxygen during free‐breathing

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Renal metabolic rate of oxygen (rMRO2) reflects the kidney's metabolic efficiency, making it a potential biomarker for early‐stage kidney disease. This study introduces an ungated, free‐breathing MRI sequence in comparison to its breath‐hold counterpart to noninvasively measure whole‐organ rMRO2.

A Multi‐Mode Analytical Frequency Modulation Input‐Shaping Control

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In rest‐to‐rest maneuvers, input shapers like the double step (DS), zero vibration (ZV), and zero vibration derivative (ZVD) are widely utilized to eliminate residual vibrations in single‐mode systems. These shapers can be used to eliminate residual oscillations in multimode systems, given that the higher frequencies are odd multiples of the ...

Fluid Dynamics and Infrared Stealth of Marine IRS Devices: A Review

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Infrared suppression (IRS) devices for naval ships play a crucial role in reducing the infrared radiation signature of high‐temperature exhaust, thereby enhancing the survivability of ships against infrared‐guided weapons. This paper provides a comprehensive review of recent advancements in the design and optimization of IRS devices.

Biological sex and age‐associated changes in muscle and brain health in Chronic Obstructive Pulmonary Disease: A large cross‐sectional study

Nutrition in Clinical Practice, EarlyView.
Abstract Background Biological sex plays a role in systemic features of patients with Chronic Obstructive Pulmonary Disease (COPD). We investigated whether male and female COPD patients show distinct trajectories in muscle and brain health decline during aging. Methods In total 228 patients (age >50 years) with stable COPD (GOLD: II–IV) were stratified
