abstract background: labor is a physiologic process, and consideration of labor pain and relieving that is among the major components of maternal care. application of some labor position can lay the fetus better in pelvic canal direction. the present study aimed to investigate the effect of laying the mother in three labor positions on the pain severity in the second, third, and fourth stages o...

Abstract Following a renaissance from the 1980s, electrochemistry has developed into sophisticated interdisciplinary science integrating solid‐state and surface further, biological sciences. Most remarkably, even single‐molecule can now be addressed. Single‐molecule covers transition metal complexes, organic redox molecules, fragile biomolecules, molecular‐scale hybrids between metallic nanopar...

Generative mechanisms which lead to empirically observed structure of networked systems from diverse fields like biology, technology and social sciences form a very important part of study of complex networks. The structure of many networked systems like biological cell, human society andWorld Wide Web markedly deviate from that of completely random networks indicating the presence of underlyin...

Memristive systems, namely, resistive systems with memory, are currently attracting considerable attention. Here we show that even the simplest one-dimensional network formed by the most common memristive elements with voltage threshold bears nontrivial physical properties. In particular, by taking into account the single element variability we find (1) dynamical acceleration and slowing down o...
