ARM TrustZone is the most widely used mobile trusted execution environment (TEE) technology today. Its hardware-enabled isolated provides reliable assurance of secure storage credentials in devices. However, research on managing stored TEE throughout lifecycle devices has received little attention recent years, and generally face usability problems caused by device events. Aiming at risk inform...

Collective migration of eukaryotic cells plays a fundamental role in tissue growth, wound healing and immune response. The motion, arising spontaneously or in response to chemical and mechanical stimuli, is also important for understanding life-threatening pathologies, such as cancer and metastasis formation. We present a phase-field model to describe the movement of many self-organized, intera...

Neuron-glia interactions are crucial for the establishment of normal connectivity in the nervous system during development, but the molecular signals involved in these interactions are largely unknown. Here we show that differentiating photoreceptors in the developing Drosophila eye influence the proliferative and migratory behavior of the subretinal glia through the diffusible factors Decapent...

the purpose of this study is to investigate the relationshipbetween the mutual funds flows and the return of stock index using 65mutual funds in the period of 2008 to 2011.in this study, the dailychanges of the total number of units of mutual funds and the changesof the total values of units of mutual funds were considered as acriteria for the net of mutual funds flows. the results of johansen ...

In this paper, we use the “2002 Chinese Household Income Project Survey” (CHIPS2002) data to examine how heterogeneous social interactions affect the peer effect in the rural–urban migration decision in China. We find that the peer effect, measured by the village migration ratio, significantly increases the individual probability of outward migration. We also find that the magnitude of the peer...

Cross-cloud data migration is one of the prevailing challenges faced by mobile users, which an essential process when users change their phones to a different provider. However, due insufficient local storage and computational capabilities smart phones, it often very difficult for backup all from original cloud servers in order further upload downloaded new To solve this problem, we propose eff...

Collective cell migration is a fundamental process, occurring during embryogenesis and cancer metastasis. Neural crest cells exhibit such coordinated migration, where aberrant motion can lead to fatality or dysfunction of the embryo. Migration involves at least two complementary mechanisms: contact inhibition of locomotion (a repulsive interaction corresponding to a directional change of migrat...
