background: identify the optimal technique of radiotherapy for patients with high grade glioma. our initial year of experience with rapidarc radiation therapy. materials and methods: planning ct scans of 50 patients with grade iv glioma were reviewed and three plan sets by 3d conformal radiotherapy (3dcrt), intensity modulated radiotherapy (imrt) and rapid arc (ra) were generated and the plans ...

During ventilation, the lungs may serve as accessory pumps for forward blood flow. We have noted significant hemodynamic improvement in several patients during short periods of vigorous hand ventilation with the Ambu bag and tried to reproduce the hemodynamic improvement in the management of four patients with profound low cardiac output syndrome secondary to right ventricular (RV) failure foll...

With all the excitement around IoT (Internet of Things), big data and cognitive computing the impact of wearable electronics on the manufacturing environment frequently gets lost in the noise. However, the capability and capacity to serve the needs driven by these trends falls on the shoulders of the electronics industry and in particular SMT assembly. This paper explores the seemingly conflict...

UNLABELLED The innate immune response is generally considered to have an important role in tissue remodeling after resistance exercise. PURPOSE The purpose of this study was to compare changes in markers of monocyte recruitment after an acute bout of high-intensity (HVY) versus high-volume (VOL) lower-body resistance exercise. METHODS Ten resistance-trained men (24.7 ± 3.4 yr, 90.1 ± 11.3 k...

This research project aimed at producing a high-speed and web-based indexing model solution for high-volumes of metadata database content. Such solution would enable users to index their metadata content within reasonable periods of time. Also, it would enable them to debug and profile the entire indexing process. The produced model involves retrieving high-volume of database metadata content, ...

IMPORTANCE For the management of thyroid diseases, there have been few studies aimed at examining the association between disparities and outcomes. OBJECTIVE To measure the effects of race, ethnicity, and socioeconomic status on outcomes following thyroid surgery. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional analysis of 62,722 thyroid procedures identified in the Nationwide Inpatient S...

This paper presents the design and implementation of a GPU-based ray tracing system for dynamic scenes consisting of a set of individual, non-deformable objects. The triangles of each object are organized in a separate Kd-tree. A bounding volume hierarchy (BVH) is built on top of these Kd-trees. The BVH is updated and uploaded into GPU memory on a frame-by-frame basis, whereas the Kd-trees are ...

Despite evidence of increased risks, a large number of patients still have surgery in low-volume hospitals. To better understand why, we used Medicare data to study the regional availability of high-volume hospitals. More than half of patients undergoing three procedures in low-volume hospitals lived in regions lacking a high-volume hospital. Some regions simply lacked enough cases to support a...
