It is now well understood that there is a minimal requirement on the channel
quality in feedback stabilization via a communication channel. In the case of SISO plant and SISO channel. This minimal channel quality is given in terms of the degree of instability of the plant to be stabilized. For a MIMO system controlled via a MIMO communication channel, things are much less clear. In this talk, we will examine some known results and also speculate some possible directions. In the MIMO study, majorization theory plays an important role.

What do Microsoft, Genentech, Google, Securian, Target, and Ernst & Young have in common? All these companies (and many more) have used LinkedIn to recruit candidates for employment. Kay Luo, Director of Corporate Communications at LinkedIn, explains why, The main reason that companies are using LinkedIn is to find passive job candidates. Another reason why companies are using LinkedIn, is because referrals from their employees are highly valued because they typically have a higher success/retention rate (hence the popular employee referral bonuses).

Although the network clustering literature has focused on undirected networks, many networks are directed. For example, communication networks contain asymmetric relationships, representing the flow of information from one person to another. This talk will (1) demonstrate that co-clustering, instead of clustering, is more natural for many directed graphs, (2) propose a spectral algorithm and a statistical model for co-clustering, (3) show some asymptotic results, and (4) present a preliminary analysis of a citation network from Arxiv.
