Using first-principles calculations, we investigate the chemisorption of H, N, and P atoms on a graphene substrate with or without Stone–Thrower–Wales (STW) defects. Energetically, all three atoms are preferred to adsorb onto the defect sites by an energy difference of 0.683–2.143 eV. In both the intrinsic and defected graphene, H atom adsorbs on top of a C atom, while N and P atoms adsorb at t...

There is debate about how fossil hominin pedal morphology relates to terrestrial habits. Were early hominins adapted to a bipedal lifestyle with a significant arboreal component, or were they more dedicated to a terrestrial lifestyle? The proximal articular surfaces of the metatarsals (MT) are examined in Gorilla, Pan, Hylobates, and habitually shod and unshod Homo using three-dimensional morph...

Tissue engineering is a clinical approach toward the development of dynamic molecular delivery that can restore and improve regeneration. The 3D models and regenerative principles applied during implant guided dental surgery open new approaches for tissue constructs favoring sinus lift and implant placement. Purpose: The aim of the present clinical study was to determine evidence that synergy b...

OBJECTIVES The present study examines the utility of three measures of premorbid intellectual functioning in closed head injury, the National adult reading test (NART), the Cambridge contextual reading test (CCRT), and the spot the word test (STW). METHODS In the first experiment, a group of 25 patients with closed head injury were compared with 50 healthy controls and 20 orthopaedic trauma c...

use of auxiliary elements in refining and betterment of engineering properties of soil have gained attention since a long time ago. nowadays the effectiveness and capability of the soil reinforcing technique for giving proper practical solutions in various projects have resulted in this technique quickly gaining a place in geotechnical engineering. in this paper, the results of laboratory studi...

We utilize a Monte Carlo simulation scheme based on the bond fluctuation model to simulate settlement of adhesive particles onto sinusoidally corrugated substrates. The particles are composed of a hard inner core with either an effective potential shell or a "soft" adhesive shell made of flexible arms attached to the particle surface. These chains adhere via either the effective potential shell...

This paper focuses on observer based fault reconstruction for a class of nonlinear uncertain systems with Lipschitz nonlinearities. An adaptive-gain Super-Twisting (STW) observer is developed for observing the system states, where the adaptive law compensates the uncertainty in parameters. The inherent equivalent output error injection feature of STW algorithm is then used to reconstruct the fa...

The nanoscale structure of shock waves in high strength AlN ceramics is studied using molecular-dynamics simulations. Impacts using four independent crystallographic directions, with particle velocities in the range 0.8–4.0 km/s, reveal the generation of a welldefined two-wave structure, consisting of an elastic precursor followed by a wurtzite-torocksalt structural transformation wave (STW). I...

We studied the diagnostic predictive power of transrectal ultrasonography (TRUS) coupled with semen volume in cases of distal seminal tract sub-obstruction. As a gold standard for diagnosis we used seminal tract washout (STW). Non-azoospermic subjects (n = 112) were submitted to transrectal ultrasonography because of suspected excretory infertility or other andrological pathologies, before perf...

STW 5 (Iberogast), a phytomedicine agent consisting of a fixed combination of nine individual plant extracts, is widely used in the treatment of dyspepsia and motility related disorders. Little if anything is known on the possible influence on electrophysiological properties of intestinal smooth muscle by which STW 5 causes its beneficial effects. The aim of the present study was to investigate...
