We consider an important class of non-symetric networks that lies between the class of general networks and the class of symmetric networks, where group theoretic methods still apply – namely, networks admitting “interior symmetries”. The main result of this paper is the full analogue of the Equivariant Hopf Theorem for networks with symmetries. We extend the result of Golubitsky, Pivato and St...
تعداد کروموزوم های سوماتیک و کاریوتایپ در پنج گونه از onopordum از ایران مورد بررسی قرار گرفت. نتایج ما سطح دیپلویید ( 342n=) را در تمام گونه ها تایید نمود. کاریوتایپ برای گونه های o. leptolepis, o. heteracanthum وo. carduchorum برای اولین بار ارائه می شوند. علاوه بر آن اعداد کروموزومی برای گونه های o. armenum, o. carduchorumو o. acanthium برای اولین بار از ایران گزارش شده و تایید کننده گز...
the karyotype of pike from anzali lagoon in the south caspian sea basin have been investigated by examining metaphase chromosomes spreads obtained from gill epithelial and kidney cells. the chromosomes spreads were stained with 7% giemsa solution for 15 min and examined under a light microscope. appropriate metaphase plates were photographed in order to prepare karyotype. all specimens had a di...
Joint source-channel coding using structured oversampled filters banks applied to image transmission
This paper proposes a new joint source and channel coder based on the BCH codes on the reals, in which the signal protection (analogous to a signal interpolation) is performed before compression. This allows a better tradeoff in high accuracy compression, since part of the distortion introduced by the compression can be corrected by the "channel decoder". Furthermore, we propose as an optimal c...
chromosomal patterns of experimental animals are useful tools for cytogenetics research and animal breeding. chromosome investigations of the hairless guinea pig are rare, therefore, karyotype of hairless guinea pigs (twelve male and female) was studied using metaphase spreads of bone marrows and g banding techniques. the chromosomes diploid number was 2n= 64 and polymorphism of three type chro...
Carbon aerogels modified with graphene oxide, graphene and CNT as symetric supercapacitor electrodes
We investigated whether karyotype analysis and mutational screening by next generation sequencing could predict outcome in 101 newly diagnosed chronic lymphocytic leukemia patients with high-risk features, as defined by the presence of unmutated IGHV gene and/or 11q22/17p13 deletion by FISH and/or TP53 mutations. Cytogenetic analysis showed favorable findings (normal karyotype and isolated 13q1...
Background & Aims: To investigate associations between serum levels of folic acid with the results of the first trimester Down syndrome screening methods and fetal karyotype in high-risk pregnant women. Materials & Methods: In this cross-sectional study, serum levels of folic acid in 232 high risk pregnant women were measured using ELISA method and Down syndrome screening was done using karyot...
In this study, for the first time in Iran, the karyotype of bigmouth Lotak, Cyprinion macrostomum Heckel, 1843, was investigated through examining metaphase chromosomes of seven fish with mean weight 30±5g caught by electrofishing from Godarkhosh River in Ilam Province. To stimulate cell divisions, fish were injected intraperitoneally two times by phytohemagglutinin (PHA). The cell divisions we...
Background & Aims: The study of karyotype in several cases is the first step in the diagnosis of genetic disorders. The purpose of this study was to investigate the karyotype of a number of individuals with a range of possible genetic disorders. Materials & Methods: This researchis a descriptive cross-sectional study. Sampling was done after obtaining necessary permissions and written consent ...
