Computational requirements for real-time ptychographic image reconstruction.

Ptychographic imaging techniques can be coupled with tomographic image reconstruction techniques to obtain cross-sectional 3D images with resolution on the nanometer scale. However, such ptychographic x-ray computed tomography (PXCT) techniques require the collection of a large number of diffraction patterns. This work derives a set of equations that can be used to calculate the rate at which data can be collected given an experimental setup.

Design and development of a run-time monitor for multi-core architectures in cloud computing.

Cloud computing is a new information technology trend that moves computing and data away from desktops and portable PCs into large data centers. The basic principle of cloud computing is to deliver applications as services over the Internet as well as infrastructure. A cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources.

Performance standards for therapeutic abdominal paracentesis.

Large-volume paracentesis, the preferred treatment for patients with symptomatic tense ascites due to cirrhosis, has traditionally been performed by physicians as an inpatient procedure. Our objectives were to determine (1) whether large-volume paracentesis could be performed safely and effectively by gastrointestinal endoscopy assistants and as an outpatient procedure, (2) whether the risk of bleeding was associated with either thrombocytopenia or prolongation of the prothrombin time, and (3) the resources used for large-volume paracentesis. Gastrointestinal endoscopy assistants performed 1,100 large-volume paracenteses in 628 patients, 513 of whom had cirrhosis of the liver.

Prehospital treatment of acute asthma in a rural state.

Background: Acute asthma exacerbations can be life threatening and are recognizable to emergency medical service (EMS) personnel; however, the therapies and medications which these emergency service personnel can use to treat exacerbations are limited. Several studies have demonstrated the effective use of beta2-agonist therapy in the treatment of patients complaining of wheezing or dyspnea, yet few EMS personnel can administer them.

Objective: The purpose of this study was to determine what therapeutic interventions emergency personnel around the state of New Mexico could use when responding to a call for a severe asthma exacerbation.

Common problems in the diagnosis of immunodeficiency in children.

Primary immunodeficiency (ID) has an incidence of 1 in 10,000 and may have significant morbidity and mortality if not diagnosed and treated early. Children with signs and symptoms suggestive of immunodeficiency are often seen first by their paediatrician or family medical practitioner. For these reasons, it is essential that primary care physicians both of children and adults should be able to recognize the signs and symptoms of immunodeficiency and be knowledgeable about the screening procedures useful in the diagnosis of these diseases.
