androgenic alopecia as a physiologic process and benign prostatic hyperplasia (bph) as a pathologic process in the older population are androgen-dependent processes influenced by 5-alpha reductase enzyme which converts testosterone to dihydrotestosterone. this cross sectional study was done to evaluate the relationship between androgenic alopecia and bph. 150 men older than 50 years old, who pr...

We point out that in (open) string compactifications with non-zero NS-NS B-field we can have large Kaluza-Klein thresholds even in the small volume limit. In this limit the corresponding gauge theory description is in terms of a compactification on a non-commutative space (e.g., a torus or an orbifold thereof). Based on this observation we discuss a brane world scenario of noncommutative unific...

The efficacy of any animal signal is constrained by the range over which it remains above the sensory threshold of potential receivers. The spatial area in which reliable detection occurs defines active space; this is influenced by signal structure, the signalling environment and the sensory characteristics of receivers. Identification of the factors influencing active space has provided valuab...

Handheld devices are enhancing many aspects of our lives. As increasingly complex devices appear with decreasing form factors, haptics may become an essential tool for interacting with them. In this regime of operation, issues of power, weight and volume are of significant importance. The haptic thresholds of the index finger for active exploration of a two dimensional virtual environment for t...

Abstract We study minimum-energy pathways (MEPs) between the branches of metastable helical structures in chiral nematic liquid crystals (CNLCs) subjected to electric field applied across cell. By performing stability analysis we have found that, for with non-vanishing half-turn number, threshold (critical) voltage Freedericksz transition is an increasing function free twisting wave number. The...

This study provides minimum economic growth (or GDP growth) critical masses or thresholds that should be exceeded in order for demand-side mobile money factors to favorably drive innovations financial inclusion developing countries. The considered are accounts, the phone used send money, and receive money. empirical evidence is based on tobit regressions. For positive net relationships establis...
