For the past time a number of algorithms were presented to produce a deterministic finite automaton (DFA) for the regular expression. These algorithms could be divided into what they used as an initial data from which to produce DFA. The method to produce DFA from non-deterministic finite automaton (NFA) by a subset construction could be generalized for extended regular expressions, including i...

We report a case of deep femoral artery (DFA) aneurysm associated with pre-vasculo-Behcet status. A 34-year-old man with a history of recurring oral and genital ulcers was admitted complaining of worsening left thigh pain over the previous 30 days. Computed tomography showed a left DFA aneurysm (60 mm × 70 mm), concomitant aneurysms in the popliteal and carotid arteries, and deep vein thrombosi...

Dynamic financial analysis (DFA) models an insurance company’s cash flow in order to forecast assets, liabilities, and ruin probabilities, as well as full balance sheets for different scenarios. In the last years DFA has become an important tool for the analysis of an insurance company’s financial situation. Furthermore it is a valuable instrument for solvency control, which is now becoming qui...

During the winter seasons of 1993 and 1994, a total of 256 nasopharyngeal aspirates (NPA) from infants aged less than 1 year old admitted to the pediatric ward of Princess Rahma Hospital, northern Jordan, with bronchiolitis and/or pneumonia, were tested for the presence of respiratory syncytial virus (RSV) using direct immunofluorescence assay (DFA) and cell culture (CC). Of the 256 specimens, ...

We present a framework for learning DFA from simple examples. We show that e cient PAC learning of DFA is possible if the class of distributions is restricted to simple distributions where a teacher might choose examples based on the knowledge of the target concept. This answers an open research question posed in Pitt's seminal paper: Are DFA's PAC-identi able if examples are drawn from the uni...

The first saccharide ester of a dehydrodiferulic acid (DFA) other than 5-5-DFA has been isolated from maize bran insoluble fibre after acidic hydrolysis and fractionation by gel chromatography and semi-preparative RP-HPLC. HPLC-MS along with 1D, 2D and 3D NMR spectra provided the requisite structural evidence that it is the di-5-O-l-arabinosyl ester of 8-O-4-DFA. Although a range of DFAs have b...

The authors tested fluctuation analyses (DFA) of EEGs upon auditory stimulation in waking and hypnotic states as related to topography and hypnotizability. They administered the Hypnotic Induction Profile (HIP), Dissociation Experience Scale, and Tellegen Absorption Scale to 10 healthy volunteers and measured subjects' EEGs while the subjects listened to sounds, either selecting or ignoring ton...

Detrended Fluctuation Analysis (DFA) is widely used to assess the presence of long-range temporal correlations in time series. Signals with long-range temporal correlations are typically defined as having a power law decay in their autocorrelation function. The output of DFA is an exponent, which is the slope obtained by linear regression of a log-log fluctuation plot against window size. Howev...

An association between dental fear and anxiety (DFA) has been confirmed for children younger than 8 years, but this association in older children is less clear. The aim of this study was to fill this knowledge gap by studying DFA in older children and their parents with validated measures. This cross-sectional study, conducted at Community Health Centre Mostar, Bosnia and Herzegovina, included ...

During the 2009 novel influenza (H1N1) pandemic, the sensitivity of direct immunofluorescence assay (DFA) for H1N1 infection was 62% (266/429) of that of the polymerase chain reaction (PCR) test. The sensitivity of the DFA differed significantly with the age of patients: the sensitivity was the highest (71.8%) for patients aged <10 years and the lowest for patients aged ≥30 years. The sensitivi...
