In this paper we investigate the peak-to-average power ratio (PAR) and its effects on the performance of Zipper-VDSL systems. The spectrum and the out of band power when passing through a nonlinear device is also investigated. We further evaluate the performance with a recently proposed PAR reduction technique for orthogonal frequency division multiplexing (OFDM). PAR reduction of Zipper-VDSL m...
background: about 15% of couples have infertility problems which 40% of them are related to the male factors. genetic factors are candidate for about 10% of male infertility conditions. among these, azfa, azfb, azfc and azfd regions on the yq are considered most important for spermatogenesis. microdeletions of these regions are thought to be involved in some cases of azoospermic or oligospermic...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
OBJECTIVES We sought to analyze the very late outcomes of patients treated for in-stent restenosis (ISR) according to treatment allocation and 10 prespecified variables. BACKGROUND Long-term results (>2 years) of patients with ISR undergoing repeat coronary interventions are not well established. METHODS The Restenosis Intrastent: Balloon angioplasty versus elective Stenting (RIBS) randomiz...
We investigated arm perfusion and metabolism during upper body exercise. Eight average, fit subjects and seven rowers, mean +/- SE maximal oxygen uptake (VO2 max) 157 +/- 7 and 223 +/- 14 ml O2. kg(-0.73).min(-1), respectively, performed incremental arm cranking to exhaustion. Arm blood flow (ABF) was measured with thermodilution and arm muscle mass was estimated by dual-energy X-ray absorptiom...
The objective of this study was to compare biological parameters such as length, weight, age, caviar production indices, caviar/weight, growth, condition factor and sex ratios of Persian sturgeon (Acipenser persicus Borodin, 1897) and Russian sturgeon (A. gueldenstaedti Brandt & Ratzeburg, 1833) in the Caspian Sea during 1990-2014. The results showed that a variety of differences between this t...
The Y chromosome is one of the smallest human chromosomes with an average size of 60 million base pairs (Mb). Between X and Y chromosomes, exchange is limited to small pseudoautosomal regions (PAR) of the X-Y pair (see Figure 1). During male meiosis, recombination only takes place at the most distal short arm (PAR 1) and at the tip of the Y chromosome long arm (PAR 2). For most of its length (t...
In this paper, we describe some initial results of a project aiming at development of a programmablecompliance, inherently safe robot arm for applications in anthropic environmnets. In order to obtain safety in spite of worst-case situations (such as unexpected delays in teleoperation, or even controller failure), we will consider achieving compliance by mechanical rather than by control design...
