The main goal of the present set of studies was to examine the efficiency of executive control processes and, more specifically, the control processes involved in task set inhibition and preparation to perform a new task in attention deficit hyperactivity disorder (ADHD) and non-ADHD children. This was accomplished by having ADHD children, both on and off medication, and non-ADHD children perfo...

ÐCache coherent nonuniform memory access (CC-NUMA) multiprocessors provide a scalable design for shared memory. But, they continue to suffer from large remote memory access latencies due to comparatively slow memory technology and large data transfer latencies in the interconnection network. In this paper, we propose a novel hardware caching technique, called switch cache, to improve the remote...

Tracheobronchial disruption is an uncommon but severe complication of double lumen endotracheal tube placement. The physical properties of a double lumen tube (large external diameter and length) make tracheobronchial injury more common than that associated with smaller single lumen endotracheal tubes. Here we present the case of an iatrogenic left main bronchus injury caused by placement of a ...

We propose a numerical dissipation switch, which helps to control the amount of present in central-upwind schemes. Our main goal is reduce without risking oscillations. This achieved with help more accurate estimate local propagation speeds parts computational domain, are near contact discontinuities and shears. To this end, we introduce switch parameter, depends on distributions energy x - y -...

background: defects in b cell class switch recombination (csr) are a heterogeneous and yet very uncommon group of disorders which all have a genetic basis uniformly leading to hyper igm (higm) syndrome. due to the rare frequency of these conditions, a very small number of case series have been conducted on the affected patients. objective: to shed some light on the morbidity and mortality regar...

In a prospective study of 13 patients requiring pneumonectomy for unilateral post-tuberculous lung destruction the left side was found to be affected in 12. Review of a further 172 cases showed the left lung to have been destroyed in 109 (63%). It is suggested that this predominance of the left side is due to the anatomical characteristics of the left main bronchus and that disordered haemodyna...

Emergency Department, complaining of exertional dyspnea. A review of his medical history revealed that 3 years earlier he had tried to swallow a knife. It was removed from the esophagus by endoscopy. Two years before admission he told his relatives that he had swallowed another knife, but they did not believe him. Posteroanterior (Fig. 1) and lateral (Fig. 2) views of the chest were obtained, d...

One of the difficulties with PWM switching converters is high switching loss and electromagnetic interference due to switching at non-zero voltage and current, which limits the operating frequency. In order to reduce the converter volume and weight (by increasing the frequency) and reducing switching losses, zero voltage and current switching methods are recommended. In this paper, four main ze...
