Roentgen stereophotogrammetry is the most accurate Roentgen technique for three-dimensional assessment of micromotion of orthopaedic implants. The reported accuracy of Roentgen Stereophotogrammetric Analysis (RSA) ranges between 0.05 and 0.5 mm for translations and between 0.15j and 1.15j for rotations. Because of the high accuracy of RSA, small patient groups are in general sufficient to study...

The purpose of the present study was to compare the performance in repeated sprint ability (RSA) and repeated changes-of-direction (RCOD) among elite soccer players with different age categories. Forty-nine elite soccer players from the same club and from different age categories (Pro2: n = 8, U19: n = 18, U17: n = 13, and U15: n = 10) participated in this study. Each player was tested in both ...

Respiratory sinus arrhythmia (RSA) is the modulation of heart rate along with respiration. Individual differences in RSA reflect parasympathetic cardiac control. Low RSA is linked to emotional dysregulation, perhaps from an inability to modulate the parasympathetic nervous system to emotion. For the current study, pictures of varying emotional contents were presented to participants with low an...

background: congenital toxoplasmosis is an important cause of spontaneous abortion worldwide. however, there is limited information on detection and genotypic characterization of t. gondii in women with recurrent spontaneous abortion (rsa). the aim of this study is molecular detection and genotypic characterization of t. gondii in formalin-fixed, paraffin-embedded fetoplacental tissues (ffpts) ...

Root system architecture (RSA) impacts plant fitness and crop yield by facilitating efficient nutrient and water uptake from the soil. A better understanding of the effects of soil on RSA could improve crop productivity by matching roots to their soil environment. We used x-ray computed tomography to perform a detailed three-dimensional quantification of changes in rice (Oryza sativa) RSA in re...

We survey four variants of RSA designed to speed up RSA [12] decryption and signing. We only consider variants that are backwards compatible in the sense that a system using one of these variants can interoperate with systems using standard RSA. 1 . I N T R O D U C T I O N RSA is the most widely deployed public key cryptosystem. It is used for securing web traffic, e-mail, and some wireless dev...

Background and purpose - Radiostereometric analysis (RSA) is an accurate method for measurement of early migration of implants. Since a relation has been shown between early migration and future loosening of total knee and hip prostheses, RSA plays an important role in the development and evaluation of prostheses. However, there have been few RSA studies of the upper limb, and the value of RSA ...

The RSA-768 (270 decimal digits) was factored by Kleinjung et al. on December 12, 2009, while the RSA-704 (212 decimal digits) was factored by Bai et al. on July 2, 2012. The RSA-200 (663 bits) was factored by Bahr et al. on May 9, 2005, while he RSA-210 (696 bits) was factored by Propper on September 26, 2013. In this paper the author will discuss an estimation method to approach the lower/upp...

Respiratory sinus arrhythmia (RSA) is related to cardiac vagal outflow and the respiratory pattern. Prior infant studies have not systematically examined respiration rate and tidal volume influences on infant RSA or the extent to which infants' breathing is too fast to extract a valid RSA. We therefore monitored cardiac activity, respiration, and physical activity in 23 six-month old infants du...

On August we completed the factorization of the bit digit number RSA with the help of the Number Field Sieve factoring method NFS This is a new record for factoring general numbers Moreover bit RSA keys are frequently used for the protection of electronic commerce at least outside the USA so this factorization represents a breakthrough in research on RSA based systems The previous record factor...
