Idology and Its Applications in Public Security and Network Security [PDF]

, 2017
Fraud (swindling money, property, or authority by fictionizing, counterfeiting, forging, or imitating things, or by feigning other persons privately) forms its threats against public security and network security. Anti-fraud is essentially the identification of a person or thing.

Sharing Data for Public Security [PDF]

, 2010
Data sharing is a valuable tool for improving security. It allows integrating information from multiple sources to better identify and respond to global security threats. On the other side, sharing of data is limited by privacy and confidentiality. A possible solution is removing or obfuscating part of the data before release (anonymization), and, to ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
