According to the operating conditions and load requirements of the lifting exoskeleton, a harmonic reducer with large reduction ratio and high torque output is designed in this paper (Xiang Guoqi, 2005).From the perspective of structural dynamics (Donghui et al., 2015; Zuguang et al., 2011), use ANSYS simulation software to study the motion intensi
In Samoa Islands, a powerful earthquake took place at 17:48:10.99 UTC (06:48:10.99 LT) on 29 September 2009 with a magnitude Mw=8.1.Using ICE (Instrument Champ Electrique) and IMSC (Instrument Magnetic Search Coil) experiments onboard the DEMETER (Detection of Electromagnetic Emissions Transmitted from Earthquake Regions) satellite we have surveyed
Icebergs are big chunks of ice floating on the ocean surface, and melting of icebergs contributes for the major part of freshwater flux into ocean.Dynamic monitoring of the icebergs in Antarctica and accurate estimation of their volume are important for predicting the trend of freshwater budget of the Southern Ocean.The iceberg freeboard is a key p
Cell spheroids are a widely used model to investigate cell-cell and cell-matrix interactions in a 3D microenvironment in vitro.Most research on cell spheroids has been focused on their response to various stimuli under static conditions.Recently, the effect of flow on cell spheroids has been investigated in the context of tumor invasion Hair Care i
