Muscle attenuationMuscle massMuscle qualityObesityObjectives: Diabetes mellitus is a major global public health issue. Cross-sectional studies have demonstrated that skeletal muscle quality and quantity by computed tomography (CT) is related to glucose metabolism. However, to our knowledge, no longitudinal...

Devices are disclosed for attenuating vibration transmission between a first mass and a second mass. An embodiment includes a housing defining a chamber configured to be pressurized with a fluid, at least one first pivot element coupled to the housing and the first mass, and at least one second...
They accounted for about 40% of the measured PM mass concentration and the relative proportion of sulfate was the largest. The variation of the chemical composition seemed not to have noticeable effect on the comparability of the two methods. 展开 ...
Equivalent mass-spring models are developed to theoretically predict the vibration attenuation ranges. Bandgap merging effects induced by the damping of the 3D printed meta-structures are further investigated, and remarkably enlarged attenuation bands are experimentally captured. The metamaterial-based lattice...

For the latter, the absorption would result from acoustic energy transfer into the membrane if the membrane was caused to stretch due to the mass movement. In our work, although we consider damping due to motion of the membrane, the dominant absorption mechanism is due to the MPP and to ...

However, below 1.0Ω/square will largely increase the difficulty of mass production and result in a very high cost in final application. On the other hand, although thin metal layer has good conductivity in electrical characteristic, but the metal also has much limitation in the application to ...
