Polyamides composed of N-methylpyrrole (Py), N-methylimidazole (Im) and N-methylhydroxypyrrole (Hp) amino acids linked by beta-alanine (beta) bind the minor groove of DNA in 1:1 and 2:1 ligand to DNA stoichiometries. Although the energetics and structure of the 2:1 complex has been explored extensively, there is remarkably less understood about 1:1 recognition beyond the initial studies on netr...

background: prevention of slipping accidents requires provision of adequate friction through the use of suitable combinations of footwear and underfoot surfaces. shoe sole tread groove is one of the important factors on friction coefficient during walking. objective: to measure the effect of different shoe sole tread groove depths and different surfaces on the required quotient of friction (q),...

no tillage systems can reduce operating costs, enhance soil organic matter, ameliorate soil structure and prevent environmental damage caused by stubble burning. however, the lack of an appropriate direct drill for the hardened soil of arid areas reduces adequate soil-seed contact and, thus, the system has shown contradictory results in past tests. developing a direct drill to place the seed an...

BACKGROUND Given the unreliable self-report in patients with dementia, pain assessment should also rely on the observation of pain behaviors, such as facial expressions. Ideal observers should be well trained and should observe the patient continuously in order to pick up any pain-indicative behavior; which are requisitions beyond realistic possibilities of pain care. Therefore, the need for vi...

Abstract The safety of human-robot interaction is an essential requirement for designing collaborative robotics. Thus, this paper aims to design a novel variable stiffness actuator (VSA) that can provide safer physical VSA follows the idea modular design, mainly including module and drive module. transmits motion from in roundabout manner, making modularization possible. As key component module...

In this paper we present how the leader election protocol specified in [1] was modelled with the GROOVE tool set. The goal of this protocol is to find the smallest of a set of uniquely numbered processes arranged in a ring, without having a central controller available. GROOVE is a graph transformation tool, which uses directed simple graphs with labelled edges. In the remainder of this article...
