Denaturing High-Performance Liquid Chromatography (DHPLC) is a recently developed technique forthe detection of single nucleotide polymorphisms (SNPs) and mutations. It involves the comparisonbetween two or more DNAs as a mixture of denatured and reannealed PCR products. The methodologyis based on the principle of reversed phase liquid chromatography and uses a unique DNA sepa...

in this paper‎, ‎we study the extremal‎ ‎ranks and inertias of the hermitian matrix expression $$‎ ‎f(x,y)=c_{4}-b_{4}y-(b_{4}y)^{*}-a_{4}xa_{4}^{*},$$ where $c_{4}$ is‎ ‎hermitian‎, ‎$*$ denotes the conjugate transpose‎, ‎$x$ and $y$ satisfy‎ ‎the following consistent system of matrix equations $a_{3}y=c_{3}‎, ‎a_{1}x=c_{1},xb_{1}=d_{1},a_{2}xa_{2}^{*}=c_{2},x=x^{*}.$ as‎ ‎consequences‎, ‎we g...

for vectors x, y ∈ rn, it is said that x is left matrix majorizedby y if for some row stochastic matrix r; x = ry. the relationx ∼` y, is defined as follows: x ∼` y if and only if x is leftmatrix majorized by y and y is left matrix majorized by x. alinear operator t : rp → rn is said to be a linear preserver ofa given relation ≺ if x ≺ y on rp implies that t x ≺ ty onrn. the linear preservers o...

background: some evidences showed that the secretion of uterine tube vagina and follicular fluid (ff) affects x and y-chromosome populations. sperm selection with x or y chromosome can added to oocyte for gender desired. the isolation of x y sperm have done and all efforts in this field are done to make culture media similar to in vivo condition. the objective of this study was to find if the f...
