Instability induced pressure isotropization in a longitudinally expanding system

In two previous works [arXiv:1009.4363,arXiv:1107.0668], we studied the time evolution of a system of real scalar fields with quartic coupling which shares important features with the Color Glass Condensate description of heavy ion collisions. Our primary objective was to understand how such a system, when initialized with a non-perturbatively large classical field configuration, reaches thermal equilibrium. An essential goal of these works was to highlight the role played by the quantum fluctuations. However, these studies considered only a system confined within a box of fixed volume. In the present paper, we extend this work to a system that expands in the longitudinal direction thereby more closely mimicking a heavy ion collision. We conclude that the microscopic processes that drive the system towards equilibrium are able to keep up with the expansion of the system; the pressure tensor becomes isotropic despite the anisotropic expansion.Comment: revised version to appear in PRD, new section on comparison with hydrodynamics, 32 pages, 21 figure

Identification of sleep apnea events using discrete wavelet transform of respiration, ECG and accelerometer signals

Sleep apnea is a common sleep disorder in which patient sleep patterns are disrupted due to recurrent pauses in breathing or by instances of abnormally low breathing. Current gold standard tests for the detection of apnea events are costly and have the addition of long waiting times. This paper investigates the use of cheap and easy to use sensors for the identification of sleep apnea events. Combinations of respiration, electrocardiography (ECG) and acceleration signals were analysed. Results show that using features, formed using the discrete wavelet transform (DWT), from the ECG and acceleration signals provided the highest classification accuracy, with an F1 score of 0.914. However, the novel employment of just the accelerometer signal during classification provided a comparable F1 score of 0.879. By employing one or a combination of the analysed sensors a preliminary test for sleep apnea, prior to the requirement for gold standard testing, can be performed

Information Systems Security Education: MIS Majors and Business Majors in AACSB College of Businesses

This a follow-on to previous IACIS 2018 & 2019 presentations that reported on a needs analysis of information systems security education at a 2,500-student college of business in an 11,000-student university in the Upper Midwest USA (UWEC). This year we bring in some results from a 1,700-student college of business in a 6,500- student university in the Southeast USA (GCSU). Preliminary Results are summarized in tables 1 and 2. In this study we compare MIS majors and Business Students and find little differences and conclude much more research is needed. Security of information systems is becoming more crucial by the day (Cerrudo, 2017), both conceptual knowledge and skill in tool use being necessary (Tarala, 2011). Countering this trend is the growing perception that young adults preparing to enter the work force are increasingly uninformed about basic endpoint security concepts and tools (Schaffhauser, 2015). This is counterintuitive given the widely assumed familiarity with information technology of contemporary young adults (Anderson & Rainie, 2012)
