Background: Infertility is a painful emotional experience associated with stress. Objectives: The present study aimed at determining infertility-related stress and its associated factors in infertile clients referred to the infertility clinic of Al-Zahra hospital in Rasht, Iran, in 2019. Methods: The present cross-sectional study was performed on 200 clients undergoing infertility treatment, ...

purpose the objectives of this study include: (1) determination of the attenuation of strike acceleration that tae kwon do sparring safety pads provide from kicks from olympic style tkd fighters, (2) the sex and weight differentiation in acceleration achieved within the thorax model with the roundhouse kicks. methods this prospective, observational study utilized 15 olympic style fighters from ...

We prove a Kolmogorov complexity variant of the birthday paradox. Sufficiently large random subsets strings are guaranteed to have two members x and y with low K(x/y). To this, we first show that minimum conditional between finite sets is very if they not exotic. Exotic high mutual information halting sequence.

INTRODUCTION Rheumatoid arthritis (RA) is associated with hypogalactosylation of immunoglobulin G (IgG). We examined whether a proxy measure for galactosylation of IgG N-glycans could predict response to therapy or was differentially affected by methotrexate (MTX) or TNF blockade. METHODS Using a previously defined normal phase high-performance liquid chromatography approach, we ascertained t...

OBJECTIVE To assess the reliability and validity of the Dutch version of the exercise self-efficacy scale (ESES) in persons with spinal cord injury. This is the first independent study of ESES psychometric properties, and the first report on ESES test-retest reliability. SUBJECTS/PATIENTS A total of 53 Dutch persons with spinal cord injury. METHODS Subjects completed the Dutch ESES twice, w...

The goal of statistics is to provide explanations (models) of observed data. We are given some data and have to infer a plausible probabilistic hypothesis explaining it. Consider, for example, the following scenario. We are given a “black box”. We have turned the box on (only once) and it has produced a sequence x of million bits. Given x, we have to infer a hypothesis about the black box. Clas...

the KAM theorem from a combinatorial viewpoint. Lindstedt, Newcomb and Poincaré introduced a remarkable trigonometric series motivated by the analysis of the three body problem, [P]. In modern language, [G2], it is the generating function, that I call Lindstedt series here, ~h(~ ψ) = ∑∞ k=1 ε k~h(k)(~ ψ) of the sequence ~h(k)(~ ψ) of trigonometric polynomials associated with well known combinat...

In this letter, we make a prima facie case that there could be distinct advantages to exploiting a new class of finite flux equilibrium solutions of the Quantum Boltzmann equation in semiconductor lasers.

Objectives: Time-use has become an important field of research in social and medical sciences. Time diary is the most popular method for measuring time-use that has 2 different methods of administration including yesterday and tomorrow diary. The present study aimed to compare these methods of measuring time-use.  Methods: This cross-sectional comparative study was conducted on 256 under 5-yea...
