Heat shock protein 90 (HSP90) inhibitors, such as 17-allylamino-17-demethoxygeldanamycin (17-AAG, tanespimycin), which is currently in phase II/phase III clinical trials, are promising new anticancer agents. Here, we explored acquired resistance to HSP90 inhibitors in glioblastoma (GB), a primary brain tumor with poor prognosis. GB cells were exposed continuously to increased 17-AAG concentrati...
With the growth of cyber attacks, information safety has become an important issue all over the world. Many firms rely on security technologies such as intrusion detection systems (IDSs) to manage information technology security risks. IDSs are considered to be the last line of defense to secure a network and play a very important role in detecting large number of attacks. However the main prob...
Claim of Johnson-Lindenstrauss Theorem: The Euclidean metric on any finite set X (a bunch of high dimensional points) can be embedded with distortion D = 1 + ε in R for k = O(ε−2 log n). If we lose ε (ε = 0), it becomes almost impossible to do better than that in R. Nevertheless, it is not hard to construct a counter example to this: a simplex of n+ 1 points. The Johnson-Lindenstrauss theorem g...
Of course some women, for various reasons, choose to embrace motherhood later than their own mothers. But many, like me, become older mothers because there was no other choice. It’s just how my life unfolded. . . . To suggest that most women are choosing to delay child-bearing is to suggest that women have an incredible level of control over their lives.
