The aim of this study was to investigate the correlation between the expression of pregnancy-associated plasma protein A (PAPP-A) in basal decidual cells and recurrent spontaneous abortion (RSA). A total of 39 patients with a history of RSA were enrolled into the RSA group. A further 30 females who had experienced normal pregnancy were enrolled into the control group. The mRNA expression of PAP...
RSA is a popular cryptography algorithm widely used in signing and encrypting operations for security systems. Generally, the software implementations of RSA algorithm are based on 2-prime RSA. Recently multi-prime RSA has been proposed to speed up RSA implementations. Both 2-prime and multi-prime implementations require squaring reduction and multiplication reduction of multi-precision integer...
In this paper the RSA algorithm has been implemented with feed forward artificial neural network using MATLAB. This implementation is focused on the network parameters like topology, training algoritahm, no. of hidden layers, no. of neurons in each layer and learning rate in order to get the more efficient results. Many examples are tested and it is obtained that two hidden layers feed forward ...
Many studies show that respiratory sinus arrhythmia (RSA) decreases while performing cognitive tasks. However, there is uncertainty about the role of contaminating factors such as physical activity and stress-inducing task variables. Different methods to quantify RSA may also contribute to variable results. In 83 healthy subjects, we studied RSA responses to a working memory task requiring vary...
We tested whether respiratory sinus arrhythmia (RSA) reactivity in response to each of three self-regulation tasks (bird and dragon; knock-tap; and gift wrap) would predict self-regulation performance in a sample of 101 preschool-age children (M age = 4.49, SD = .64). While controlling for baseline RSA, decreases in RSA from bird and dragon to knock-tap (but not from baseline to bird and dragon...
introduction: one factor known to cause thrombophilia in women with unexplained recurrent spontaneous abortion (rsa) is c677t polymorphism of methylenetetrahydrofolate reductase gene. this study aimed to determine the association between rsa and mthfr c677t polymorphism in iranian patients. methods: in this case-control study, 30 patients with previous history of two or more consecutive unexpla...
OBJECTIVE Low resting respiratory sinus arrhythmia (RSA) levels and blunted RSA reactivity are thought to index impaired emotion regulation capacity. Major depressive disorder (MDD) has been associated with aberrant RSA reactivity and recovery to a speech stressor task relative to healthy controls. Whether impaired RSA functioning reflects aspects of the depressed mood state or a stable vulnera...
BACKGROUND To the authors' knowledge, no study has investigated the concurrent repeated, high-intensity (RHIA) and repeated-sprint activity (RSA) of intermittent team-sport competition. PURPOSE In this study, they report on the RSA of elite women's football competition. In addition, they describe the nature of RHIA (eg, striding and sprinting activities) that involve a high energy cost and ar...
A Mobile Ad hoc Network (MANET) consists of multiple wireless mobile devices that form a network on the fly to allow communication with each other without any infrastructure. Due to its nature, providing security in these networks is challenging. Threshold Cryptography (TC) provides a promise of securing these networks. In this paper, we discuss our RSA-based Threshold Cryptography (RSA-TC) and...
Background. The development of a microcomputer-based device permits quick, simple, and noninvasive quantification of the respiratory sinus arrhythmia (RSA) during quiet breathing. Methods and Results. We prospectively and serially measured the radionuclide left ventricular ejection fraction and the RSA amplitude in 34 cancer patients receiving up to nine monthly bolus treatments with doxorubici...
