Abstract Neuromorphic hardware systems emulate the parallel neural networks of human brain, and synaptic weight storage elements are crucial for enabling energy-efficient information processing. They must represent multiple data states be able to updated analogously. In order realize highly controllable devices, replacing high-k gate dielectric in conventional transistor structures with either solid-electrolytes that facilitate bulk ionic motion or ferroelectric oxide allows steady...
The roundhouse kick is the most commonly executed in Taekwondo competitions. Because it fastest among kicking techniques and can easily change its motion on basis of opponent’s motion, suitable for scoring points. To explore functional role segmental movements during kick, this study aimed to investigate effects various footwork biomechanical contributions body segments toe velocity kicks. Ten elite athletes performed kicks with different positions. were obtained through 3D analysis. Results...
The purpose of this study was to compare adults with knee OA and "healthy knee" controls on balance ability by matching gender, age, mass, height, BMI.Twenty-eight adults, 14 medically diagnosed osteoarthritis status, were evaluated dynamic as measured the NeuroCom Balance Master® Limits stability, tandem walk, adaptation test protocols.Outcomes reaction time, movement velocity, maximum excursion, directional control for limits stability speed, step width, endpoint sway velocity walk test,...
We comprehensively analyze the effects of number and distribution Al2O3 atomic layer deposition (ALD) cycles into a 10-nm-thick HfO2 matrix on ferroelectric switching behavior. An ALD cycle containing one pulse for Hf (or Al) precursor water as reactant is repeated 150 times given thickness 10 nm. Spontaneous remnant polarization (Pr) enabled through formation crystalline Al-doped (Al:HfO2) by incorporating at least two evenly film under annealing 600 °C 3 min following W top electrode (TE)...
To achieve a multilevel threshold voltage in the configuration of ferroelectric field-effect transistor for high-density memories, it is crucial to finely tunable coercive ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\textit{V}_{\text{C}}\text{)}$</tex-math> </inline-formula> layer (FL). In this study, we demonstrate that use dual stacks with Zr-doped HfO notation="LaTeX">$_{\text{2}}$</tex-math>...
We investigate how the threshold voltage (
The effectiveness of adding plantar-surface texture to improve balance has been demonstrated in a variety demographics. It is critical investigate whether textured insoles can people with knee osteoarthritis (OA), who have compromised the somatosensory function affected joint and, as result, are at higher risk falling. Thus, this study investigated degree benefit from use for improving and compared OA healthy matched peers. This included eighteen healthy, aged, gender, height, weight, BMI...
As evidence of the effectiveness added plantar-surface texture to improve balance has been successful for various populations, it is important study if textured insoles may increase individuals with knee osteoarthritis (OA) who have compromised somatosensory function affected joint and correspondingly an increased risk falls.Thus, this investigated degree benefit through use improving compared OA matched-healthy peers.Fifteen fifteen healthy, aged, gender BMI matched controls completed were...
The unwanted horse problem is the most serious issue confronting equestrian industry. Thus, it recommended that retired racehorses switch to become saddle horses for ‘the second life of a racing veteran’ because training and using Thoroughbred as cost-effective option. current study aimed analyze effects conversion on gaits racehorses. Our included 12 These performed retraining 20–50 min day, five times per week three months. There are some critical findings in this study. results show...
The roundhouse kick is the most often used in Taekwondo sparring matches. In order to execute effective kicks, footwork critical. Therefore, purpose of this study was biomechanically examine effects backstep-footwork on for counterattack. Ten male university athletes executed kicks with five counterattack conditions. duration phases kick, center mass displacement, trunk, right hip, knee angles, and kicking thigh, shin, foot, toe velocities were obtained through a three-dimensional video...
