Emergency general surgery (EGS) admissions account for more than three million hospitalizations in the US annually; and interhospital transfers (IHTs) are costly. We aimed to better understand the population of transferred EGS patients and their subsequent care in a nationally representative sample.Using the 2002-2011 Nationwide Inpatient Sample, we identified patients aged ≥18 years with an EGS noncardiovascular...
WSN applications are prone to bugs and failures due to their typical characteristics, such as being extensively distributed, heavily concurrent, and resource restricted. In this paper, we propose and develop a flexible and iterative WSN debugging system based on sequence mining techniques. At first, we develop a data structure called the vectorized Probabilistic Suffix Tree (vPST), an elastic model...
Given the pervasive nature of malicious mobile code (viruses, worms, etc.), developing statistical/structural models of code execution is of considerable importance. We investigate using probabilistic suffix trees (PSTs) and associated suffix automata (PSAs) to build models of benign application behavior with the goal of subsequently being able to detect malicious applications as anything that deviates...
The trauma system in the United Sates is in the process of evolution. Although it is recognised that a systems approach to trauma care is ideal, this concept has yet to be realised fully due to political, financial and geographic considerations. The pre-hospital controversies of in-the-field care, resuscitation, and transport are still debated. In-hospital care is governed by a trauma service using...
