The Romanov Theorem Revised
نویسندگان
چکیده
Let P be the set of all primes and P 2 = P ∪ {p 1 p 2 : p 1 , p 2 ∈ P}. We prove that the sumset 2 P + P 2 = {2 p + q : p ∈ P, q ∈ P 2 } has a positive lower density.

Association between Melatonin Receptor 1A (MTNR1A) Gene Polymorphism at the MnlI Site and Production Traits in Shal and Crossbreeding between Shal and Romanov
The objective of this study was to evaluate the relationship between polymorphism at the MnlI site of MTNR1A gene and production traits of Shal and Romanov crossbreeding. The crossbreeding between Shal and Romanov was done on 600 Shal ewes. For this reason, Shal ewes were laparoscopically and artificially inseminated with the semen of Romanov breed. For the preparation of genomic DNA, a total o...
متن کاملA Note on the Descent Property Theorem for the Hybrid Conjugate Gradient Algorithm CCOMB Proposed by Andrei
In [1] (Hybrid Conjugate Gradient Algorithm for Unconstrained Optimization J. Optimization. Theory Appl. 141 (2009) 249 - 264), an efficient hybrid conjugate gradient algorithm, the CCOMB algorithm is proposed for solving unconstrained optimization problems. However, the proof of Theorem 2.1 in [1] is incorrect due to an erroneous inequality which used to indicate the descent property for the s...

This study was conducted to compare the feedlot performance and growth traits of Lori-Bakhtiari (n=39), Romanov × Lori-Bakhtiari (n=38) and Pakistani × Lori-Bakhtiari crossbred (n=12) lambs during two consecutive years. Lambs were weaned at the age of 90 ± 5 days. After weaning and preliminary fattening period, three groups of lambs were fattened for 90 days in the same conditions. The resul...

Prolactin is secreted from the anterior pituitary gland and plays an important role in the mammary gland development, differentiation and lactation. The aim of current study was to evaluate prolactin receptor gene polymorphisms in the Shal breed and Shal×Romanov crossbreeds. For this purpose, after blood sampling of animals and extraction of DNA using phenol chloroform method, two fragments of ...
متن کاملGlobal convergence and quasi-reversibility for a coefficient inverse problem with backscattering data
A globally convergent numerical method is developed for a 2-d Coefficient Inverse Problem for a hyperbolic PDE with the backscattering data. An important part of this technique is the quasi-reversibility method. A global convergence theorem is proven via a Carleman estimate. Results of numerical experiments for the problem modeling imaging of plastic land mines are presented.
