Objective. This study aims to assess the impact of adaptive statistical iterative reconstruction (ASIR) on CT imaging quality, diagnostic interpretability, and radiation dose reduction for a proven CT acquisition protocol for total body trauma. Methods. 18 patients with multiple trauma (ISS ≥ 16) were examined either with a routine protocol (n = 6), 30% (n = 6), or 40% (n = 6) of iterative reco...

Numerous probability m o d e l s h a ve been suggested for information retrieval (IR) over the years. These models have been applied to try to manage the inherent uncertainty i n IR, for instance, document and query representation , relevance feedback, and evaluating the eeectiveness of IR system. On the other hand, Bayesian networks have become an established probabilistic framework for uncert...

The knock-down, mortality and 'irritancy' effects of three synthetic repellents (DEET, IR3535 and KBR 3023) on Aedes aegypti (L) (Diptera: Culicidae) were evaluated in the laboratory in the absence of animal bait. Filter paper tests were carried out to assess the knock-down effect (KDt(50) and KDt(95)) and mortality (LC(50) and LC(95)) induced by each repellent. 'Irritancy' tests were carried o...

Recently, vector-borne diseases have been resurging in endemic areas and expanding their geographic range into nonendemic areas. Such changes have refocused attention to the potential for major public health events, as naive populations are exposed to these pathogens. Personal topical repellents, recommended by the United States Centers for Disease Control and Prevention and World Health Organi...

This paper proposes a method to reduce the supply voltage IR drop of 3D stacked-die systems by implementing an on-chip Buck Converter on Top die (BCT) scheme. The IR drop is caused by the parasitic resistance of Through Silicon Vias (TSV’s) used in the 3D integration. The IR drop reduction and the overhead associated with the BCT scheme are modeled and analyzed. A 3D stacked-die system is manuf...

[HIr(IV)W6O24](7-), representing the first Ir-containing Anderson-Evans-type polyanion and the first structurally characterized Ir(IV)-based polyoxometalate, has been isolated as its hydrated sodium salt and characterized by single-crystal X-ray diffraction, mass spectrometry, and IR, UV-Vis and EPR spectroscopy. Cyclic voltammetry indicates that the Ir(IV) ions in [HIrW6O24](7-) can undergo re...

Treatment (>/=24 h) of cultured bovine adrenal chromaffin cells with ketoacidosis-related concentrations (>/=3 mM) of acetoacetate (but not beta-hydroxybutyrate, acetone, and acidic medium) caused a time- and concentration-dependent reduction of cell surface (125)I-insulin binding by ~38%, with no change in the K(d) value. The reduction of (125)I-insulin binding returned to control nontreated l...

PURPOSE Evaluation of 15,000 computed tomography (CT) examinations to investigate if iterative reconstruction (IR) reduces sustainably radiation exposure. METHOD AND MATERIALS Information from 15,000 CT examinations was collected, including all aspects of the exams such as scan parameter, patient information, and reconstruction instructions. The examinations were acquired between January 2010...
