Consistability: Describing usually consistent systems (2009)
S. Aiyer, Eric Anderson, Xiaozhou Li, Mehul A. Shah, Jay J. Wylie
Current weak consistency semantics provide worst-case guarantees to clients. These guarantees fail to adequately describe systems that provide varying levels of consistency in the face of distinct...
ORIGINAL ARTICLE Concurrent maintenance of rings (2008)
Xiaozhou Li, Jayadev Misra, C. Greg Plaxton, X. Li, J. Misra
Abstract A central problem for structured peer-topeer networks is topology maintenance, that is, how to properly update neighbor variables when nodes join or leave the network, possibly concurrently....
Online Hierarchical Cooperative Caching ∗ Theory of Computing Systems (2008)

Active and Concurrent Topology Maintenance (2004)
Xiaozhou Li, Jayadev Misra, C. Greg Plaxton
Depending on whether the neighbor variables are immediately updated once a membership change occurs, there are two general approaches to topology maintenance: the passive approach and the active...
Raman Spectroscopy of Serum for Cancer Detection (2003)
Laser induced auto- fluorescence and Raman spectra of serum from cancerous and normal people are measured and analyzed. Three Raman peaks were consistently observed from normal blood serum emission...
Spectral Changes of Lung Cancer Serum in the Process of Tumor Evolution (2003)
Li, Xiaozhou, He, Zhongqiu, Jin, Huiqiang
The discrimination and changes of serum fluorescence and Raman spectrum for normal human, lung cancer patient and one after operation in different period and extent were studied. We kept close watch...
On name resolution in peer-to-peer networks (2002)
An efficient name resolution scheme is the cornerstone of any peer-to-peer network. The foundation of an efficient name resolution scheme is a dynamic network topology that determines the neighbor...
Batch updates for key trees (2000)
Xiaozhou Li, Y. Richard Yang, Mohamed G. Gouda, Simon S. Lam
[2] introduced the concept of key trees for secure group communications and discussed how to update a key tree due to a single rekey request (a join or a leave). In a real application, however, rekey...
