Blood-Based Lead Biomarkers and Sarcopenia Indicators in Older Adults. [PDF]

J Cachexia Sarcopenia Muscle
ABSTRACT Background Chronic exposure to low levels of lead (Pb) remains a widespread public health issue, especially among older adults. While its neurotoxic and cardiovascular effects are well recognized, its potential role in accelerating age‐related musculoskeletal decline is less understood.

Tailored Stitching and Vertical Stacking for High-Voltage Multifunctional Structural Batteries with Enhanced Electrochemical-Mechanical Coupling. [PDF]

Adv Sci (Weinh)
A stitched, vertically stacked CFRP structural battery uses Kevlar interlaminar threads and selective PP/Elium® thermoplastics to maintain tight electrode spacing and robust electrolyte wetting. The architecture sustains electrochemical performance under bending and delivers higher pack voltage via through‐thickness series connections without ...

Bluer in the city: urban male lizards exhibit more intense sexual coloration and lower parasite loads than non-urban males. [PDF]

Integr Zool
The urban environment may exert different selective pressures on sexually selected traits than more pristine environments. Our study shows that sexual coloration is more saturated (bluer) in male lizards from urban environments than in male non‐urban lizards. The average parasite load is lower in urban lizards than in non‐urban lizards.

Will urban air mobility fly? The efficiency and distributional impacts of UAM in different urban spatial structures [PDF]

Transportation Research Part C: Emerging Technologies, 2021
Recent technological developments open up possibilities for introducing a vast number of novel mobility concepts in urban environments. One of these new concepts is urban air mobility (UAM). It makes use of passenger drones for on-demand transport in urban settings, promising high travel speeds for those willing and able to pay.

Performance Analysis of Aircraft-to-Ground Communication Networks in Urban Air Mobility (UAM)

2021 IEEE Global Communications Conference (GLOBECOM), 2021
Abstract To meet the growing mobility needs in intra-city transportation, urban air mobility (UAM) has been proposed in which vertical takeoff and landing (VTOL) aircraft are used to provide on-demand service. In UAM, an aircraft can operate in the corridors, i.e., the designated airspace, that link the aerodromes, thus avoiding the use of complex ...
