BACKGROUND Automatic detection of the 1st (S1) and 2nd (S2) heart sounds is difficult, and existing algorithms are imprecise. We sought to develop a wavelet-based algorithm for the detection of S1 and S2 in children with and without pulmonary arterial hypertension (PAH). METHOD Heart sounds were recorded at the second left intercostal space and the cardiac apex with a digital stethoscope simu...

Avian infectious bronchitis is an acute and highly contagious disease that mainly causes respiratory symptoms in poultry. A number of serotypes and variants of the viral agent with poor cross-protection are the major problem to achieve desired immunity from vaccination. The S1 subunit of S glycoprotein (spike) is the major determinant of IBV so that a minor change in amino acid sequence of this...

background: s1 radiculopathy is a high prevalence illness and its early diagnosis is of crucial importance. several reports have revealed the efficacy of magnetic stimulation in diagnosis of this condition. we conducted this study to compare mmep latency and mmep amplitude in patients with s1 radiculopathy and healthy controls in shohadaye tajreash hospital in 2007. materials and methods: this ...

By a proof by assumption, or for short an assumption proof, I mean the following. The proof proves a conclusion of the form ‘If P then Q’. It proceeds by making a sequence of statements S1, . . . , Sn (possibly with added commentary), where P is S1, Q is Sn, and for each Si with i > 1 there are earlier Sj . . . such that the conditional ‘If Sj . . . , then Si’ is already known. The reason for c...

In this paper, we prove a version of the typed Böhm theorem on the linear lambda calculus, which says, for any given types A and B, when s1 and s2 (respectively, u1 and u2) are different closed terms of A (resp. B), there is a term t such that t s1 =βηc u1 and t s2 =βηc u2 . Several years ago, a weaker version of this theorem was proved, but the stronger version was open. As a corollary of this...

Given strings S1, S2, and P , the constrained longest common subsequence problem for S1 and S2 with respect to P is to find a longest common subsequence lcs of S1 and S2 such that P is a subsequence of this lcs. We present an algorithm which improves the time complexity of the problem from the previously known O(rnm) to O(rnm) where r, n, and m are the lengths of P, S1, and S2, respectively. As...

1. The fluorescence changes accompanying the binding of ATP and adenosine 5'-[gamma-thio]triphosphate (ATP gamma S) to myosin subfragment 1 (S1) and actomyosin subfragment 1 (actoS1) have been reinvestigated at 20 degrees C and 1 degree C, pH 7.0, 0.1 M-KCl. 2. Two successive fluorescence enhancements are observed following ATP binding to both S1 and actoS1. 3. The slow fluorescence change has ...

The constraints defined in Eq. 1 (for every si and s ′ i) are linear constraints on P . So are the constraints P (s1, . . . , sn) ≥ 0 and ∑ P (s1, . . . , sn) = 1. We conclude that the set of correlated equilibria define a polyhedron, and moreover, that we can find a correlated equilibrium which maximizes any linear function of P using linear programming. Specifically, we can find the correlate...

The frequency of Helicobacter pylori infection in population can depend on the organism resistance, genetic condition, and bacterial strains virulence. A vacA gene, of mosaic structure, which encodes vacuolating cytotoxin is one of the known genes of H. pylori. The existence of several different genotypes of s and m regions enables the formation of numerous combinations of vacA gene genome. The...
