Multilocus sequence typing (MLST) provides a new approach to molecular epidemiology that can identify and track the global spread of virulent or antibiotic-resistant isolates of bacterial pathogens using the Internet. MLST databases, together with interrogation software, are available for Neisseria meningitidis and Streptococcus pneumoniae and ...

Given a multiset \(S\) of integers, let also \(P(S)\) be the set of all finite sums of distinct terms taken from \(S\); in particular \(0 \in P(S)\). Fix an integer \(p\ge 2\) and a nonempty finite multi \(A\) of positive integers. Define the multiset \[ S_pA:=\{p^i a: i \ge 0, a \in A\}.

THE DIHEDRAL-TYPE ADJACENCY SEQUENCES
JP Journal of Algebra, Number Theory and Applications, 2018Summary: In this paper, a dihedral-type adjacency sequence is defined by using the adjacency matrix which is obtained via a Cayley graph of the dihedral group. Also, we consider the semi-groups which are produced by the generating matrices and we study their orders. Furthermore, we examine the dihedral-type adjacency sequence in groups.

Type Sequences of Numerical Semigroups
Semigroup Forum, 1998A numerical semigroup (briefly n.s.) \(S\subseteq\mathbb{N}\cup\{0\}\) is a subsemigroup of \((\mathbb{N},+)\) with \(0\in S\). Note that every n.s. is finitely generated. If \(g(S)=\max\{x\in\mathbb{Z}\setminus S\}\) is the so called Frobenius number of \(S\) and \(n(S)=\text{Card}(\{0,1,\dots,g(S)\}\cap S)\) then \(S=\{0=s_0,s_1,\dots,s_{n-1},s_n=g(S)

There is a great need to develop molecular techniques for the typing of Helicobacter pylori isolates since classical bacteriological assays, such as serotyping or lysotyping, are lacking. Such techniques would provide the microbiologist with the tools necessary to differentiate one strain from another one (essential for epidemiological studies), to ...

Polynomial Sequences of Interpolatory Type
Studies in Applied Mathematics, 1993Continuing his previous investigations [ibid. 79, No. 1, 65-92 (1988; Zbl 0696.05004), \((*)\) Adv. Math. 58, 89-108 (1985; Zbl 0583.05010) and ibid. 85, 215-242 (1991)], the author studies sequences of polynomials which are well suited for Hermite interpolation from the point of view of convergence, computing the coefficient, evaluations and ...

Sequencing-Based Typing of HLA
2007Human leukocyte antigen (HLA) typing is largely performed by use of PCR-based techniques in patients that require stem cell transplantation. In this chapter, HLA typing by sequencing-based typing techniques is described.

Multivariate Sequences of Binomial Type
Studies in Applied Mathematics, 1977Using the notion of convolution of binomial sequences it is possible to show that Sheffer sequences, cross sequences, and Steffensen sequences are only mild generalizations of ordinary sequences of binomial type.

It has recently become apparent that many bacterial populations undergo extremely high levels of horizontal genetic exchange, such that traditional clonal models of bacterial diversity are now inadequate (1-3). Such recombination is especially apparent in naturally transformable bacteria such as members of the genus Neisseria (4). This has implications
