Constructing efficient and secure encryption schemes is an important motivation for modern cryptographic research. We propose simple and secure constructions of hybrid encryption schemes that aim to keep message expansion to a minimum, in particular for RSA-based protocols. We show that one can encrypt using RSA a message of length |m| bits, at a security level equivalent to a block cipher of κ...

in oil industry, spontaneous imbibition is an important phenomenon in recovery from fractured reservoirs which can be defined as spontaneous uptake of a wetting fluid into a porous solid. spontaneous imbibition involves both cocurrent and countercurrent flows. when a matrix block is partially covered by water, oil recovery is dominated by cocurrent imbibition i.e. the production of non wetting ...

Introduction: Spinal cord injury (SCI) is one of the most serious clinical diseases, which not only affects the patient's physical and mental status, but its effects will be spread to family and community. After severe spinal cord injury, astrocytes of the central nervous system (CNS) become reactive astrocytes, and play the main role of glial scar formation. The scar is a major obstacle to r...

BACKGROUND This study aimed to examine the association between renal recovery status at hospital discharge after acute kidney injury (AKI) and long-term mortality following transcatheter aortic valve replacement (TAVR). METHODS We screened all adult patients who survived to hospital discharge after TAVR for aortic stenosis at a quaternary referral medical center from January 1, 2008, through ...

INTRODUCTION In this study, we report the results of our experience of therapeutic plasma exchange (TPE) for neuroimmunologic disorders performed at our hospital over a seven-year period. METHODS We retrospectively reviewed the medical records of 91 patients (53 male, 38 female) who had been treated at our center with TPE. RESULTS 60 patients with Guillain-Barrè syndrome (GBS), 23 with myas...
