OBJECTIVES The accuracy and precision of two new methods of model-based radiostereometric analysis (RSA) were hypothesised to be superior to a plain radiograph method in the assessment of polyethylene (PE) wear. METHODS A phantom device was constructed to simulate three-dimensional (3D) PE wear. Images were obtained consecutively for each simulated wear position for each modality. Three comme...

The hash-and-sign RSA signature is one of the most elegant and well known signatures schemes, extensively used in a wide variety of cryptographic applications. Unfortunately, the only existing analysis of this popular signature scheme is in the random oracle model, where the resulting idealized signature is known as the RSA Full Domain Hash signature scheme (RSA-FDH). In fact, prior work has sh...

BACKGROUND This study compared the outcomes between patients with proximal humerus fractures (PHF) who underwent acute reverse total shoulder arthroplasty (RSA) to those who underwent an alternative initial treatment before requiring (secondary) RSA. METHODS Patients who underwent RSA after suffering a PHF were identified. Two year clinical follow-up was required for inclusion. Patients were ...

Based on the Chinese Remainder Theorem (CRT), Quisquater and Couvreur proposed an RSA variant, RSA-CRT, to speed up RSA decryption. Then, Wiener suggested another RSA variant, Rebalanced RSA-CRT, to further accelerate RSA-CRT decryption by shifting decryption cost to encryption cost. However, such an approach makes RSA encryption very timeconsuming because the public exponent e in Rebalanced RS...

OBJECTIVES No data regarding phenotypic assets of circulating lymphocytes in anti-phospholipid syndrome (APS) are reported in the literature. Role of anti-phospholipid antibodies (aPL) in recurrent spontaneous abortion (RSA) remains uncertain, while natural killer (NK)-cells are involved in RSA pathogenesis. In this study, patients affected with APS without RSA, APS with RSA and RSA without aPL...

The temporal relationship between sniffing and the limbic 19 rhythm was studied in rats during odor discrimination reversal learning. The I3 rhythm was monitored as rhythmic slow wave activity (RSA) in the dorsal hippocampal formation, and cyclic nasal airflow (sniffing) was monitored with a thermocouple in the nasal cavity. The training procedures required animals to perform a sequence of whol...

Depression is associated with protracted despondent mood, blunted emotional reactivity, and dysregulated parasympathetic nervous system (PNS) activity. PNS activity is commonly indexed via cardiac output, using indictors of its level (resting respiratory sinus arrhythmia [RSA]) or fluctuations (RSA reactivity). RSA reactivity can reflect increased or decreased PNS cardiac output (RSA augmentati...

An (α, β, γ)-LSBS RSA denotes an RSA system with primes sharing α least significant bits, private exponent d with β least significant bits leaked, and public exponent e with bit-length γ. Steinfeld and Zheng showed that LSBS-RSA with small e is inherently resistant to the BDF attack, but LSBS-RSA with large e is more vulnerable than standard RSA. In this paper, we improve the BDF attack on LSBS...

BACKGROUND Respiratory sinus arrhythmia (RSA) is a noninvasive measure of parasympathetic tone that has been related to emotion regulatory capacity. While some previous work indicates that clinically depressed persons exhibit lower levels of RSA than do normal controls, there is nevertheless considerable between-subject variation in RSA among depressed persons. The current study evaluated the s...

LSBS-RSA denotes an RSA system with modulus primes, p and q, sharing a large number of least signi…cant bits. In ISC 2007, Zhao and Qi analyzed the security of short exponent LSBS-RSA. They claimed that short exponent LSBS-RSA is much more vulnerable to the lattice attack than the standard RSA. In this paper, we point out that there exist some errors in the calculation of Zhao & Qi’s attack. Af...
