Endophthalmitis is a rare but sight-threatening infection after cataract surgery. Roughly one third of eyes remain blind after treatment. We report United States population-based data on microbiological investigations and treatment patterns plus risk factors for poor outcomes.Retrospective cohort study.Medicare beneficiaries from 5 states in whom endophthalmitis developed within 6 weeks after cataract...
Wireless monitoring employing distributed sniffers has been shown to complement wire side monitoring using SNMP and base station logs since it reveals detailed PHY (e.g., signal strength, spectrum density) and MAC behaviors (e.g, collision, re- transmissions), as well as timing information (e.g., back-off time), which are often essential for network diagnosis. Due to hardware limitations, wireless...
We consider the problem of optimally assigning p sniffers to K channels to monitor the transmission activities in a multi-channel wireless network. The activity of users is initially unknown to the sniffers and is to be learned along with channel assignment decisions while maximizing the benefits of this assignment, resulting in the fundamental trade-off between exploration versus exploitation. We...
