A Deep Learning Pipeline for Identification of Motor Units in Musculoskeletal Ultrasound

open access: yesIEEE Access, 2020
Skeletal muscles are functionally regulated by populations of so-called motor units (MUs). An MU comprises a bundle of muscle fibers controlled by a neuron from the spinal cord.

Analysis of Rebound Rate of Wet Shotcrete Based on Experiment and Discrete Element Method

open access: yesShock and Vibration, 2022
Wet shotcrete support is the main support method for underground engineering construction at present. The rebound rate is one of the indicators to evaluate the support effect, and a lower rebound rate will improve the construction effect of wet shotcrete.

Ligand-responsive RNA mechanical switches [PDF]

open access: yesRNA Biology, 2015
Ligand-responsive RNA mechanical switches represent a new class of simple switching modules that adopt well-defined ligand-free and bound conformational states, distinguishing them from metabolite-sensing riboswitches. Initially discovered in the internal ribosome entry site (IRES) of hepatitis C virus (HCV), these RNA switch motifs were found in the ...

Influence of Modulus of Base Layer on The Strain Distribution for Asphalt Pavement

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2021
In order to investigate the influence of modulus of the base layer on the strain distribution for asphalt pavement, the modulus ratio of the base layer and the AC layer (Rm) is introduced as a controlled variable when keeping modulus of the AC layer as a
