    Mechanism Underlying Tissue Cryotherapy to Combat Obesity/Overweight: Triggering Thermogenesis by Suvaddhana Loap, Richard Lathe

    Published 2018-01-01
    “…Local adipose tissue (AT) cooling is used to manage obesity and overweight, but the mechanism is unclear. The current view is that acute local cooling of AT induces adipocyte cell disruption and inflammation (“cryolipolysis”) that lead to adipocyte cell death, with loss of subcutaneous fat being recorded over a prolonged period of weeks/months. …”

    Delegation authorization mechanism with controllable permissions propagation for IoT devices sharing by Yubo SONG, Shanshan QI, Aiqun HU

    Published 2019-04-01
    “…In order to solve the problems of privilege sensitivity protection and the abuse of authorization by the agent when the device owner delegates authorization in IoT devices sharing environment,a trust-based delegation mechanism for controllable partial permissions was proposed with the trust access control model and the proxy signature.This mechanism generates trust values and authorization policies based on the relationship between the users,and implements controllable partial authority delegation through the proxy signature.According to the security analysis,the mechanism can meet the security attributes such as verifiability,non-repudiation,distinguishability,identifiability and non-abuse required by the permission transfer,and ensure the controllable security transfer of the device owner's permission.The problem of over authorization of an intermediary agent is effectively prevented.…”
