The objective was to describe the sexual life satisfaction of couples in the climacteric stage and determine whether there are differences between the perception of satisfaction and the sex life of each partner. We studied 142 couples obtained by stratified sampling of family health centers, Concepción, Chile. 66% of women and 84% of men reported being very or somewhat satisfied with their sex ...

BACKGROUND Voluntary Medical Male Circumcision (VMMC) is an effective strategy to reduce the risk of HIV infection. Studies conducted in the Dominican Republic (DR) suggest that acceptability of VMMC among men may be as high as 67%. The goal of this clinical trial was to assess the acceptability, uptake and safety for VMMC services in two areas of high HIV prevalence in the country. METHODS T...

We study the bound states of brane/antibrane systems by examining the motion of a probe antibrane moving in the background fields of N source branes. The classical system resembles the point-particle central force problem, and the orbits can be solved by quadrature. Generically the antibrane has orbits which are not closed on themselves. An important special case occurs for some Dp-branes movin...

Recently, Brenner et al. proposed a symmetric somewhat homomorphic encryption scheme and applied it to solve some practical problems, such as the Millionaires’ problem, which only need to evaluate circuits of limited depth. It is claimed that the security of their scheme is built on the hardness of integer factorization. In this paper, we use the Euclidean Greatest Common Divisor (GCD) algorith...

Here we present previously unpublished optical spectra of supernova (SN) 2001ig, a Type IIb SN, from about a week after explosion until nearly one year later. The earliest spectrum consists of only a few broad absorption features, but soon more common Type II SN features including hydrogen P-Cygni profiles and helium absorption become apparent. At later times, as the H features fade and the He ...

Strassen's 1969 algorithm for fast matrix multiplication 2] is based on the possibility to multiply two 2 2 matrices A and B by using 7 multiplications instead of the usual 8. The corresponding formulas are an important part of any algorithms course, but, unfortunately, even in the best textbook expositions (see, e.g., 1]), they look very ad hoc. In this paper, we show that the use of natural s...

Verifiable computing (VC) uses cryptography to delegate computation to untrusted workers. But in most VC schemes, the delegated program must first be arithmetized – expressed as a circuit with multiplication and addition over a finite field. Previous work has compiled subsets of languages like C, LLVM, and bespoke assembly to arithmetic circuits. In this paper, we report on a new DSL for VC, ca...

A key recovery attack allows an attacker to recover the private key of an underlying encryption scheme when given a number of decryption oracle accesses. Previous research has shown that most existing Somewhat Homomorphic Encryption (SHE) schemes suffer from this attack. In this paper, we propose efficient key recovery attacks against two NTRU-based SHE schemes, which have not gained much atten...

This paper presents direct comparisons of related visualization and hot film measurement studies of the nonlinear, late stages of transition in a boundary layer. The preceding nonlinear stages of the transition process are well documented in previous studies. Both the visualizations and measurements were performed with controlled disturbance conditions excited by an instability wave in a flat-p...
