Vibrational relaxation of highly excited HO2 in collisions with O2

We investigate the relaxation of highly vibrationally excited HO2 in collisions with vibrationally cold O2. The calculations employ the quasiclassical trajectory method and a global double many-body expansion potential energy surface for HO4(2A). Both deactivation and activation processes are observed, with the rate constants being found to be strongly influenced by the donor internal energy content. It is also found that the title process may not be ignorable when modelling the ozone budget in the middle atmosphere.http://www.sciencedirect.com/science/article/B6TFN-4F60NH4-C/1/f1c401808edfc7e0a83201a53ad912d

SMART—An Integrated Wireless System for Monitoring Unattended Patients

Monitoring vital signs and locations of certain classes of ambulatory patients can be useful in overcrowded emergency departments and at disaster scenes, both on-site and during transportation. To be useful, such monitoring needs to be portable and low cost, and have minimal adverse impact on emergency personnel, e.g., by not raising an excessive number of alarms. The SMART (Scalable Medical Alert Response Technology) system integrates wireless patient monitoring (ECG, SpO2), geo-positioning, signal processing, targeted alerting, and a wireless interface for caregivers. A prototype implementation of SMART was piloted in the waiting area of an emergency department and evaluated with 145 post-triage patients. System deployment aspects were also evaluated during a small-scale disaster-drill exercise
