BACKGROUND Primary percutaneous coronary intervention (PCI) is recommended for ST-segment elevation myocardial infarction (STEMI) patients even when the patient must be transported to a PCI-capable hospital. This study aimed to evaluate the long-term clinical outcomes of STEMI patients who were transferred for primary PCI compared to patients who arrived directly to PCI-capable hospitals. MET...
In the European framework SESAR, the need to increase the air traffic capacity mo-tivated the 4D (space + time) aircraft trajectory planning.In order to produce, on one side, a pre-tactical trajectory planning (an aircraft avoidcongested areas or areas with bad weather) and on the other side a tactical trajectoryplanning (generating sets of 4D conflict-free trajectories), we int...
Many localization mechanisms have been proposed for use in wireless sensor networks (WSN). In this paper, we investigate propagation properties of localization through simple trilateration across the network. We show that location information propagates following the theory of percolation. We empirically study the relationship between convergence speed of this process vs. node and network param...
TD-SCDMA is an innovative wireless radio standard for a physical layer 3G air interface, approved as one 3GPP standards by ITU in May 2000. Based on the unique advantages of the physical layer, this paper investigates network-based methods to obtain the angle of arrival (AOA) and time of arrival (TOA) via subspace tracking and channel impulsive estimation. By incorporating the spatial–temporal ...
In an experiment designed to measure the time of arrival of individual photons, it is of critical importance to understand the behavior of the system in the event that more than one “detectable” photon arrives at the detector element. This document explores some of the characteristics and relationships associated with the recorded photon arrival time. The analysis is in the context of discrete ...
abstract background: as any delay in the onset of milk production and ejection in the first few days after delivery can cause breast-feeding failure, this study has been done to determine factors that may affect the onset time of lactation in vaginal and cesarean section deliveries with and without labor pain (elective). methods: 300 partujient mothers selected from two private and university h...
