Legionella micdadei (Pittsburgh pneumonia agent) was identified by direct fluorescent-antibody (DFA) examination of lung tissue in six of seven persons diagnosed previously as having L. micdadei pneumonia only by histopathology and in four persons who also had positive cultures of the organism. No cross-reactions occurred with monospecific DFA conjugates prepared against Legionella pneumophila ...

Recently, Holzer et al. gave a method to decide whether the language accepted by a given deterministic finite automaton (DFA) can also be accepted by some reversible deterministic finite automaton (REV-DFA), and eventually proved NL-completeness. Here, we show that the corresponding problem for nondeterministic finite state automata (NFA) is PSPACE-complete. The recent DFA method essentially wo...

The medial circumflex femoral artery (MCFA) usually branches from the deep femoral artery (DFA). It may also branch from the femoral artery (FA). In this study 100 inguinal regions of 50 cadavers were investigated. In 79 extremities (79%) MCFA branched from DFA, while in 15 (15%) it branched from FA. In four extremities (4%) MCFA was found to be double; in each case one of MCFAs branched from F...

This paper presents an integrated system for assembly planning and redesign, based on \Design for Assembly (DFA)" principles. DFA criteria are used in the generation of cost eeective assembly sequences for mechanical products, using a technique known as \Backward Assembly Planning". If the assembly cost can be further reduced by redesign, the system performs \Reverse Engineering", produces a de...

BACKGROUND Adenovirus (ADV) infections were difficult to diagnose in the past, and many infections were unrecognized. Direct fluorescent assay (DFA) for the rapid diagnosis of ADV infection, as part of a viral respiratory panel, became available at Primary Children's Medical Center (Salt Lake City, UT) in December 2000. OBJECTIVE To describe children with ADV infection diagnosed by DFA and vi...

Let a partial deterministic finite automaton be a DFA in which each state need not have a transition edge for each letter of the alphabet. We demonstrate that the smallest partial DFA for the set of all subwords of a given word w, Iwl>2, has at most 21w[-2 states and 3[wl-4 transition edges, independently of the alphabet size. We give an algorithm to build this smallest partial DFA from the inp...

We prospectively compared the performance of culture, direct fluorescent-antibody testing (DFA), and an in-house-developed PCR test targeting the repeated insertion sequence IS481 for the detection of Bordetella pertussis in nasopharyngeal swab specimens. We tested 319 consecutive paired specimens on which all three tests were performed. A total of 59 specimens were positive by one or more test...

pseudoaneurysms (psa) of deep femoral artery (dfa) have been reported following penetrating and blunt trauma to the thigh and orthopedic procedures of the proximal femur. we describe a case of pseudoaneurysm of dfa as a late complication of limb trauma which was confirmed by exploration in an urgent surgery. after two operations successful surgical repair was performed.

Pattern matching is a crucial task in several critical network services such as intrusion detection. In this paper we present an efficient implementation of the DFA with optimized area and optimized memory by the introduction of state minimization algorithm. By using minimized DFA the clock frequency reduces to 40% of the original and the area also reduces to 30%. This optimized architecture of...
