Intrinsic membrane proteins represent a large fraction of the proteins produced by living organisms and perform many crucial functions. Structural and functional characterization of membrane proteins generally requires that they be extracted from the native lipid bilayer and solubilized with a small synthetic amphiphile, for example, a detergent. We describe the development of a small molecule ...

This study investigates the seismic response of a horizontal axis wind turbine on two bottom-fixed support structures for transitional water depths (30-60 m), a tripod and a jacket, both resting on pile foundations. Fully coupled, nonlinear time-domain simulations on full system models are carried out under combined wind-wave-earthquake loadings, for different load cases, considering fixed and ...

There are many tools that carry cameras. Their working domain is usually surveillance, surface inspection, and broadcasting. Devices like rovers, gantries, and aircrafts often possess video cameras. The task is usually to maneuver the vehicle and position the camera to obtain the desired fields-of-view. A platform widely used in the broadcasting industry can be seen in Figure 1. The specific pa...

This paper applies dimensional synthesis to explore the geometric design of dexterous three-fingered robotic hands for maximizing precision manipulation workspace, in which the hand stably moves an object with respect to the palm of the hand, with contacts only on the fingertips. We focus primarily on the tripod grasp, which is the most commonly used grasp for precision manipulation. We systema...

BACKGROUND Clinical features of Charcot-Marie-Tooth disease type 1A (CMT1A) include slowly progressive distal muscle weakness, atrophy and sensory loss. Upper-limb involvement results in reduced manual dexterity interfering with the execution of daily activities. OBJECTIVE To identify which hand function impairments are determinants of manual dexterity in CMT1A. METHODS In a cross-sectional...

There is presently a lack of knowledge of scour progression for complex offshore foundation structures, such as Tripod foundations for offshore wind turbines. Typically, scour is investigated in physical model tests. As an extension, parts of the investigations could be carried out by using numerical methods; however, such numerical methods require that all relevant processes leading to scour a...

Distinct electromagnetic properties can emerge from the three-dimensional (3D) configuration of a plasmonic nanostructure. Furthermore, the reconfiguration of a dynamic plasmonic nanostructure, driven by physical or chemical stimuli, may generate a tailored plasmonic response. In this work, we constructed a 3D reconfigurable plasmonic nanostructure with controllable, reversible conformational t...

theorization in sociological literature in general and in sociology of the family in particular suffers from conceptual confusion. the proposer of the concept: “iranian tripod system” tries to analyze the family situation and its changes in iran through modernity. the present paper studies the conceptual framework of iranian tripod system and its related quadrilateral concepts: “iranian society...

Insect locomotion requires the precise coordination of the movement of all six legs. Detailed investigations have revealed that the movement of the legs is controlled by local dedicated neuronal networks, which interact to produce walking of the animal. The stick insect is well suited to experimental investigations aimed at understanding the mechanisms of insect locomotion. Beside the experimen...
