A brief overview of some of the last decade’s developments in the Topmode/Topcolor class of models is presented. In addition, a new Topcolor type scenario, named Top-Bottom Color, is suggested. A seesaw mechanism with new weak doublet quarks has been introduced to lower the previous theoretical prediction for the large top quark mass; without a seesaw mechanism and with a low scale of Nambu Jon...
Next generation mobile networks (4G) is expected to integrate a large number of wireless technologies. However, this integration yields many challenges such as those pertaining to handoff triggering and decision making. Various approaches have been proposed to solve these problems, yet handoff initiation and network destination selection remain critical issues which are widely based on RSS (Rec...
We report a case of ventilator auto-triggering resulting from tuberculous bronchopleural fistula being managed with chest tube suction. Early recognition of bronchopleural fistula-related auto-triggering is extremely important. Auto-triggering can lead to serious adverse effects, including severe hyperventilation and inappropriate escalation of sedatives and/or neuromuscular blockers (administe...
BACKGROUND Adult mechanical ventilators have traditionally been pressure- or time-triggered. More recently, flow triggering has become available and some adult ventilators allow the choice between pressure or flow triggering. Prior studies have supported the superiority of flow triggering during continuous positive airway pressure, but few have compared pressure and flow triggering during press...
The mechanism by which antigen binding to the T cell antigen receptor (TCR) generates intracellular signaling, a process termed TCR triggering, is incompletely understood. A large body of experimental evidence has implicated multiple biophysical/biochemical effects and multiple molecules in the process of TCR triggering, which likely reflect the uniquely demanding role of the TCR in recognizing...
STUDY OBJECTIVE We evaluated the difference in work of breathing (WOB) during spontaneous ventilation with continuous positive airway pressure (CPAP) among three methods of triggering the ventilator: conventional pressure triggering, tracheal pressure triggering, and flow-by triggering. METHODS In an in vitro model of the respiratory system consisting of a bellows (lungs) in a plastic caniste...
Engineers make continuous effort to improve the sustainability of products, such as using sophisticated manufacturing approaches, conducting rigorous sustainability analysis, and including materials that decrease environmental impact. However, thoughtful sustainability efforts are sometimes hidden from customers, which are wasted sales features if customers do not know or value them. As green m...
We present a case study of dynamically triggered seismicity in Idaho and western Montana from the 2002 MW 7.9 Denali fault earthquake to investigate the relationship between measured geological discriminants and propensity for triggering. We first establish triggering. We find events that are not reported in the Advanced National Seismic System catalog in Idaho and Yellowstone following the Den...
EGRET spark chamber data collected between 1991 April 22 and 1994 August 29 have been analyzed for gamma-ray burst events independent of BATSE triggering. To date, ve gamma-ray bursts that are coincident with a trigger from the BATSE instrument have been detected in the EGRET spark chamber. The EGRET-detected bursts have high energy power law tails and, in some cases, long duration emission. Be...
[1] To explore aftershock-triggering mechanisms for the 2003 Big Bear, California earthquake sequence, we determined differential travel-times and applied the double-difference technique to relocate these events, which formed three clusters. The main cluster coincides with the 3 km long northwest striking sub-vertical mainshock fault. The other two sub-vertical clusters, located at opposite end...
