RFID is a non-contact technology using radio frequencies to achieve automatic and unique identification. It has been widely applied in various areas, such as access management, toll collection, and contact less payment. However, because the information transmission medium between readers and tags is radio frequency, it is easy for attackers to eavesdrop on(More)
OBJECTIVE To assess the biomechanical stability of asymmetrical posterior internal fixation for transforaminal lumbar interbody fusion (TLIF) with transfacetopedicular screws (TFPS). METHODS Range of motion (ROM) testing was performed in 7 fresh-frozen human cadaveric lumbar spine motion segments in flexion/extension, lateral bending, and axial rotation(More)
With the advances of network technology, electronic auctions have become increasingly popular in recent years. In 2012, Xiong proposed a bidder-anonymous auction scheme based on revocable ring signature to enhance the computation efficiency and provide a dispute protocol. Nevertheless, we find that it has design weaknesses and is vulnerable to(More)
Perovskite solar cells are emerging as one of the most promising candidates for solar energy harvesting. To date, most of the high-performance perovskite solar cells have exclusively employed organic hole-transporting materials (HTMs) such as 2,2',7,7'-tetrakis-(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD) or polytriarylamine (PTAA)(More)
In cell mitosis, cytokinesis is a major deformation process, during which the site of the contractile ring is determined by the biochemical stimulus from asters of the mitotic apparatus, actin and myosin assembly is related to the motion of membrane phospholipids, and local distribution and arrangement of the microfilament cytoskeleton are different at(More)
—The effects of cyclic stretch on apoptosis of human squamous carcinoma of tongue cell line Tca8113 were studied by Flexercell-4000 strain unit, examined and analyzed by flow cytometry.Tca8113 cells were grown on six-well culture plates and loaded by different regimen(different waveform and elongation amplitude). Results: The apoptosis rate increased(More)
