BACKGROUND AND PURPOSE Literature review revealed major variations in the anatomic characteristics of the right internal jugular vein (IJV) and carotid artery (CA) by the use of the ultrasound machine. The purpose of this study is to examine the anatomical characteristics of the right IJV and CA and to evaluate the IJV cannulation outcomes by the standard ultrasound guided vs. ultrasound locali...

Introduction: In open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. This study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment.    Materi...

W75N is a star-forming region containing various ultracompact HII regions and OH, H 2 O, and CH 3 OH maser emission. Our VLBA map shows that the OH masers are located in a thin disk rotating around an O-star which is the exciting star of the ultracompact HII region VLA1. A separate set of maser spots is connected with the ultracompact HII region VLA2. The radial velocity of OH maser spots varie...

Volume doubling rulers are described for rapid estimation of tumor volume using projection areas of single-plane images such as chest radiographs. The potential utility of the rulers derives in part from the convenient relationships that exist for the interconversion of volume, volume doubling number, and decimal log growth or cell kill. The traditional approach to tumor volume doubling time de...

The possibility of magnetic anisotropy engineering of ultrathin Co films in the scale of several dozen nanometers is investigated by magnetooptical magnetometry. In Au/Co/Au sandwiches the spin reorientation transition from the out-of-plane to the in-plane configuration is observed, when Co layer thickness exceeds 1.9 nm. Molybdenum as the underlayer suppresses the Co thickness range for which ...

Tracking of mobile objects trajectories is one of many modern applications supported by Spatiotemporal databases. Within the context of this application, queries about the present, future or past positions of the objects need to be answered. Several indexing methods have been proposed to efficiently handle such spatiotemporal queries. In the current paper, we propose a method for indexing the h...

A new low-cost, high throughput method was developed for fabricating large area quantized magnetic disks ~QMDs! using nanoimprint lithography ~NIL!, electroplating, and chemical mechanical polishing. Perpendicular QMDs with a density of 18 Gbit/in. and good uniformity over an area of 4 cm34 cm ~total 45 Gbit! have been achieved, as well as longitudinal QMDs of 30 Gbit/in. The NIL molds for the ...

From the earliest days of the Cancer Chemotherapy Cooperative Group Clinical Trials program in the 1950s, there have been concerns about the definition of response in solid tumors and the reliance on quantitative measurements. In the first clinical trial in solid tumors published by Zubrod et al. (1), “Treatment was considered to give a positive response if either the total measured tumor mass ...

Ion dynamics are investigated in a dual frequency radio frequency sheath as a function of radius above a 30 cm diameter biased silicon wafer in an industrial inductively coupled (440 kHz, 500 W) plasma etch tool. Ion velocity distribution (IVD) function measurements in the argon plasma are taken using laser induced fluorescence. Planar sheets of laser light enter the chamber both parallel and p...

Monte Carlo simulations of finite-size effects for continuum percolation in three-dimensional, rectangular sample spaces filled with spherical particles were performed. For samples with any dimension less than 10-20 times the particle diameter, finite-size effects were observed. For thin films in the finite-size regime, percolation across the thin direction of the film gave critical volume frac...
