In this note, we present a collision attack on AURORA-512, which is one of the candidates for SHA-3. The attack complexity is approximately 2 AURORA-512 operations, which is less than the birthday bound of AURORA-512, namely, 2. Our attack exploits some weakness in the mode of operation. keywords: AURORA, DMMD, collision, multi-collision 1 Description of AURORA-512 We briefly describe the speci...

Evidence-based psychological treatments (EBPT) are an effective and efficient solution for the treatment of emotional disorders (EDs). However, their implementation dissemination not yet widespread. The Unified Protocol Transdiagnostic Treatment EDs (UP), applied in a group format, could be option to implemented specialized public mental health services Spain. sample consisted 533 users centers...

This paper reduces the number of field multiplications required for scalar multiplication on conservative elliptic curves. For an average 256-bit integer n, this paper’s multiply-by-n algorithm takes just 7.47M per bit on twisted Edwards curves −x + y = 1 + dxy with small d. The previous record, 7.62M per bit, was unbeaten for seven years. Unlike previous record-setting algorithms, this paper’s...

This paper presents new speed records for arithmetic on a large family of elliptic curves with cofactor 3: specifically, 8.77M per bit for 256-bit variable-base single-scalar multiplication when curve parameters are chosen properly. This is faster than the best results known for cofactor 1, showing for the first time that points of order 3 are useful for performance and narrowing the gap to the...

Introduction. Spinal cord injury (SCI) remains a clinical challenge, despite multiple technologies to treat these injuries. Much of this difficulty lies in a lack of understanding of the factors required for neural regeneration once the cord is damaged or severed. Nonetheless, many techniques are currently being developed to promote neural regrowth after spinal cord injury, and animal models ar...

Excitotoxic neuronal injury is known to be associated with increases in cytosolic calcium ion concentrations. However, it is not known if perturbations in other intracellular ions are also associated with glutamate (GLU)-induced neuronal death. Accordingly, intracellular hydrogen ion concentrations were measured in cultured hippocampal neurons with the fluorescent dye BCECF during and after tox...

Background: It is suggested that hyperthyroidism protects against thyroid malignancy. It was suggested that the incidence of malignancy is lower in toxic multinodular goiters than in non-toxic multinodular goiters. Recent studies show controversies. Material and methods: The aim of this study is to determine the incidence and type of thyroid carcinoma in toxic and nontoxic multinodular goiter i...

Background. Total sternotomy for aortic valve replacement has been superseded by less invasive approaches such as mini-sternotomy or transcatheter procedures. There an exponential uptake in implantation (TAVI) younger and lower risk patients following recent randomized trials. This study aims to compare the outcomes of with stenosis treated minimally approaches: (mini-AVR) TAVI implantation. Me...
