Cycloposition has been measured by various methods; however, fundus photography is the most reliable method to evaluate the torsion objectively. We did a prospective study to find out the disc foveal angle (DFA) and its variation in children without squint. We included 210 eyes of 105 children between the ages of 5-15 years. DFA was calculated using standard technique after taking a fundus phot...

\Design-for-Assembly" (DFA) is a process of improving product designs for easy and low cost assembly. DFA often involves an analysis of an existing design according to qualitative criteria that are diicult to analyze. This paper introduces a quantitative shape metric for planar parts, called feedability, based on a stochastic parts feeding algorithm reported in 7]]8]. Although feedability is on...

Network intrusion detection and prevention systems commonly use regular expression (RE) signatures to represent individual security threats. While the corresponding DFA for any one RE is typically small, the DFA that corresponds to the entire set of REs is usually too large to be constructed or deployed. To address this issue, a variety of alternative automata implementations that compress the ...

oxamine administration. Urinary iron excretion induced with desferrioxamine (DFA) was estimated in 26 children with thalassaemia major. Four separate 24-hour urine collections were made-during a baseline period, after intramuscular injection of DFA 1 g, during blood transfusion with DFA 0 5 g/unit transfused blood, and during the post-transfusion period. Urinary iron, plasma iron, and total iro...

The effects of difructose anhydride III (di-D-fructofuranose-1,2':2,3'-dianhydride; DFA III) administration (3% DFA III for 4 weeks) on rat intestinal microbiota were examined using denaturing gradient gel electrophoresis (DGGE). According to DGGE profiles, the number of bacteria related to Bacteroides acidofaciens and uncultured bacteria within the Clostridium lituseburense group decreased, wh...

This paper describes a method for constructing a minimal deterministic finite automaton (DFA) from a regular expression. It is based on a set of graph grammar rules for combining many graphs (DFA) to obtain another desired graph (DFA). The graph grammar rules are presented in the form of a parsing algorithm that converts a regular expression R into a minimal deterministic finite automaton M suc...

In contrast to the conventional belief that systemic arteries dilate under hypoxia, we found that α-adrenergic contraction of rat deep femoral artery (DFA) is largely augmented by hypoxia (HVC(DFA)) while hypoxia (3% Po(2)) alone had no effect. HVC(DFA) was consistently observed in both endothelium-intact and -denuded vessels with partial pretone by phenylephrine (PhE) or by other conditions (e...

DFA minimization is an important problem in algorithm design and is based on the notion of DFA equivalence: Two DFA’s are equivalent if and only if they accept the same set of strings. In this paper, we propose a new notion of DFA equivalence (that we call weak-equivalence): We say that two DFA’s are weakly equivalent if they both accept the same number of strings of length k for every k. The m...

A direct fluorescent antibody (DFA) method was applied to sputum or tracheal aspirate from 68 patients with clinical or radiological evidence suggesting Pneumocystis carinii pneumonitis, and to 50 control patients. P. carinii was detected by DFA in specimens from 33 of the 69 clinical cases and 3 of the 50 controls. Specimens of lung from 11 of 33 DFA-positive cases were examined histologically...
