Conditions are established under which the p-adic valuations of the invariant factors (diagonal entries of the Smith form) of an integer matrix are equal to the p-adic valuations of the eigenvalues. It is then shown that this correspondence is the typical case for “most” matrices; precise density bounds are given for when the property holds, as well as easy transformations to this typical case.

Given a prime p and a natural number n, we provide simple divisibility criterions that determine whether all solvable group of order n have a nontrivial normal psubgroup, or there is exactly one group of order n without nontrivial normal psubgroups.
darafsheh and assari in [normal edge-transitive cayley graphs on non-abelian groups of order 4p, where $p$ is a prime number, sci. china math., 56 (1) (2013) 213-219.] classified the connected normal edge transitive and $frac{1}{2}-$arc-transitive cayley graph of groups of order $4p$. in this paper we continue this work by classifying the connected cayley graph of groups of order...
We present ultraviolet, optical, near-infrared photometry and spectroscopy of SN 2009N in NGC 4487. This object is a Type II-P supernova with spectra resembling those of subluminous II-P supernovae, while its bolometric luminosity is similar to that of the intermediateluminosity SN 2008in. We created SYNOW models of the plateau phase spectra for line identification and to measure the expansion ...
For p-subordinate perturbations of unbounded normal operators, the change of the spectrum is studied and spectral criteria for the existence of a Riesz basis with parentheses of root vectors are established. A Riesz basis without parentheses is obtained under an additional a priori assumption on the spectrum of the perturbed operator. The results are applied to two classes of block operator mat...
The value of the P-R interval in the study and evaluation of treatment of rheumatic carditis, a disease predominantly of the younger ages, has prompted a re-examination of the normal P-R standards for infants and children. This study reports these data as obtained from 506 normal infants and children. The data reveal that both age and heart rate exert a significant influence on the P-R interval...
The carboxylic ionophore, monensin, blocks the migration of glycoprotein-containing vesicles from the Golgi region to the plasma membrane in fibroblasts resulting in an accumulation of secretory products in the Golgi cisternae. Treatment of cultured I-cell fibroblasts with monensin (0.5,UM) decreased the abnormal excretion of f-hexosaminidase to 40% of untreated cultures within 15 min. A corres...
Background: During ICSI, motile sperm with normal morphology are selected and injected into oocyte. But integrity of chromatin is not observable. Therefore, researchers are trying for to present novel method of sperm selection with high percentage of normal chromatin. HOST test is a useful assay of functional integrity of the human sperm membrane. We decide to use HOST test after DGC for infert...
Background Sperm preparation before assisted reproductive techniques is very important for obtaining successful fertilization and pregnancy. During ICSI technique, sperms are selected based on viability and morphology. But this selection did not guarantee integrity of sperm DNA. Therefore, novel sperm selection procedures are introduced for selection of sperm with low DNA damage. One of these p...
