Thermostable Newcastle disease virus (NDV) vaccines have been used widely to control Newcastle disease for village poultry flocks, due to their independence of cold chains for delivery and storage. To explore the potential use of thermostable NDV as a vaccine vector, an infectious clone of thermostable avirulent NDV strain TS09-C was developed using reverse genetics technology. The GFP gene, al...

this paper analyzes an m/m/2 queueing system with two heterogeneous servers. both servers goes on vacation when there is no customers waiting for service after this server 1 is always available but the other goes on vacation whenever server 2 is idle. the vacationing server however, returns to serve at a low rate as an arrival finds the other server busy. the system is analyzed in the steady st...

In response to a question posed by João P. Silva, I demonstrate that an arbitrary 2n×2n real orthogonal antisymmetric matrix can be parameterized by n(n−1) continuous angular parameters. An algorithm is provided for constructing the general form for such a matrix. This algorithm is based on observation that Sp(n,R) ∩ O(2n) ∼= U(n) and employs the parameterization of the coset space SO(2n)/U(n)....

results genotype frequencies of g/a in fertile and infertile men were significantly different (χ2 = 4.16, df = 1, p = 0.041). genotype frequencies of g/g and a/ain fertile and infertile men were not significantly different (χ2 = 3.32, df = 1, p = 0.068 and χ2 = 0.521, df = 1, p = 0.47, respectively). the risk of infertility was 1.43 folds higher in individuals with the a/a genotype compared to ...

Abstract. Under a markovian evolutionary process, the expected number of substitutions per site (also called branch length) that have occurred when a sequence has evolved from another according to a transition matrix P can be approximated by − 1 4 log detP. When the Markov process is assumed to be continuous in time, i.e. P = expQt it is easy to simulate this evolutionary process for a given br...

Herein we report the case of a 10-year-old boy with an autosomal mosaic mutation who developed bacteremia. The causative agent was identified as Moraxella osloensis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rRNA gene sequencing. In the pediatric population, there have been 13 case reports of infection attributed to M. osloensis and this is the fifth...

All the conventional criterions to verify if a matrix is positive definite, Hurwitz or an M-matrix, such as Sylvester condition and Hurwitz theorem, require us to compute n determinants. This paper develops a new and simple criterion, based on a new type of Gaussian elimination process. In contrast to the traditional criterions, the new criterion only computes one determinate. Thus, the computi...
