BACKGROUND AND PURPOSE CT guidance is increasingly being used to localize the epidural space during epidural steroid injections. A common concern is that CT may be associated with significantly higher radiation doses compared with conventional fluoroscopy. The goal of this retrospective study was to determine the average dose-length product and effective dose delivered while interlaminar epidur...

OBJECTIVES To prospectively evaluate the diagnostic value and radiation dose of time-resolved CT-Angiography (4D-CTA) in pediatric patients with venous malformations using 3rd generation dual-source CT (DSCT) at 70 kVp tube voltage. METHODS Between November 2014 and August 2015, seven children (2 male, 5 female; median age, 9 years; range 3-12 years) with suspected peripheral, non-cerebral, v...

Mica is a group of clay minerals that are frequently used to fabricate electrical and thermal insulators as adsorbents for the treatment cationic pollutants. However, conventional subtractive manufacturing has drawback poor three-dimensional (3D) shape control, which limits its application. In this study, we propose digital light processing (DLP)-based additive (AM) one most effective ways addr...

We present a new database of lexical decision times for English words and nonwords, for which two groups of British participants each responded to 14,365 monosyllabic and disyllabic words and the same number of nonwords for a total duration of 16 h (divided over multiple sessions). This database, called the British Lexicon Project (BLP), fills an important gap between the Dutch Lexicon Project ...

DLP (Digital Light Processing) is in the process of dramatically changing the performance expectations with respect to stereo applications, one of the last bastions of CRT projection technology. This paper discusses stereo and the application of DLP projectors. In addition to currently available high brightness DLP projectors, we present new results with using small economical single chip DLP p...

BACKGROUND The use of pediatric CT that had recently emerged as a valuable imaging tool has increased rapidly with an annual growth estimated at about 10% per year. Worldwide, there is a remarkable increase in the number of CT examinations performed. The purposes of this study are to: (i) to measure the radiation dose and estimate the effective doses to pediatric patients during CT for chest, a...

Abstract. Let k = Fq be a finite field of odd characteristic. We find a closed formula for the number of k-isomorphism classes of pointed, and non-pointed, hyperelliptic curves of genus g over k, admitting a Koblitz model. These numbers are expressed as a polynomial in q with integer coefficients (for pointed curves) and rational coefficients (for nonpointed curves). The coefficients depend on ...
