Multicenter clinical research studies are often needed to address issues of generalizability, conditions with low incidence, adequate statistical power, and potential study bias. While pediatric research networks began work in the 1950s, and Rhode Island physicians have contributed to many of these studies, pediatric emergency medicine (PEM) collaboratives are relative newcomers. Since the mid-...

Replication of time series in microarray experiments is costly. To analyze time series data with no replicate, many model-specific approaches have been proposed. However, they fail to identify the genes whose expression patterns do not fit the pre-defined models. Besides, modeling the temporal expression patterns is difficult when the dynamics of gene expression in the experiment is poorly unde...

Ground thermal properties are prerequisites for designing the size of borehole heat exchanger. In this study, a 3D transfer model is developed to simulate response test (TRT) shallow coaxial exchanger (SCBHE), and effects ground on slope mean value inlet outlet fluid temperatures studied. The results show that strongly affected by conductivity slightly capacity, capacity only has small effect s...

This work develops an effective technique acoustic feedback cancellation (AFC) in the digital hearing aid (DHAid) devices. The normalized least mean square (NLMS) algorithm-based AFC method may suffer from a biased convergence. convergence problem is considerably resolved by prediction error (PEM)-based (PEM-AFC); however, it demonstrate slow proposed method’s main structure based two adaptive ...

OBJECTIVE To evaluate how well an inexpensive portable three-lead ECG monitor PEM identified patients with atrial fibrillation (AF) compared to a normal 12-lead ECG. DESIGN Cross-sectional method comparison study. SETTING From April 2014 to February 2015, we included patients coming to the general practice clinic "Lægerne Sløjfen", Aalborg, Denmark for a routine ECG. Patients with severe de...

OBJECTIVE To implement a curriculum using simulation and skills training to augment a Pediatric Emergency Medicine (PEM) rotation within a pediatric clerkship. BACKGROUND PEM faculty are often challenged with a high learner to teacher ratio in a chaotic clinical setting. This challenge was heightened when our pediatric clerkship's traditional 1-week PEM rotation (consisting of 4 students comp...

Layer-by-layer (LBL) self-assembly technique has been proved to be a highly effective method to immobilize the main components of the extracellular matrix such as collagen and hyaluronic acid on titanium-based implants and form a polyelectrolyte multilayer (PEM) film by electrostatic interaction. However, the formed PEM film is unstable in the physiological environment and affects the long-time...

with the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. many site-specific methods have been proposed for modeling indoor radio channels. among these methods, the ray tracing algorithm and the finite-difference time domain (fdtd) method are the most popular ones. the ray tracing approach ...

In this paper, a new power, heating and hydrogen cogeneration cycle from Sabalan geothermal two wells is proposed and analyzed. In the proposed system, a new double flash cycle and organic Rankine cycle are used for power production. A proton exchange membrane (PEM) is also used for hydrogen production and the domestic water heater is used for heating. The impacts of some design parameters, suc...
