This article presents a generalization of the RSA cryptosystem for rings with commuting ideals. An analogue Euler function ideals and concept an RSA-ideal are defined. analog ring is formulated description RSA-ideals which this possible obtained.

The RSA-768 (270 decimal digits) was factored by Kleinjung et al. on December 12 2009, and the RSA-704 (212 decimal digits) was factored by Bai et al. on July 2, 2012. And the RSA-200 (663 bits) was factored by Bahr et al. on May 9, 2005. Until right now, there is no body successful to break the RSA210 (696 bits) currently. In this paper, we would discuss an estimation method to approach lower/...

background: recurrent spontaneous abortion (rsa) is defined as three or more se-quential abortions before the twentieth week of gestation. there are evidences to sup-port an allo-immunologic mechanism for rsa. one of the methods for treatment of rsa is leukocyte therapy; however there is still controversy about effectiveness of this method. objectives: to evaluate the effectiveness of leukocyte...

Background: We performed this study in order to investigate the role of chronic endometritis (CE) in unexplained recurrent spontaneous abortion (RSA) and to determine the correlation between hysteroscopic and histologic findings of CE in patients with unexplained RSA. We also tried to find out the relation between CE and primary vs. secondary RSA. Materials and Methods: One hundred and forty-two ...

Background: It is unclear whether hemiarthroplasty (HA) or reverse shoulder arthroplasty (RS) are superior for patientswith cuff tear arthropathy (CTA) and preserved preoperative motion (elevation >90˚).Methods: This was a retrospective, single institution study. Patients who underwent RSA or HA for CTA were included ifthey had preserved preoperative motion with a minimum of 2...
