All impact analyses performed so far for the composite plates, have treated central impacts. Furthermore, investigations on influences of the in-plane biaxial compression, tension, or tension-compression preloads on various responses of the low-velocity impact, especially the indentation, have not been performed so far. In the present research, a finite element formulation is presented for resp...

This study offers evidence of asymmetry in the frequency-following response (FFR), a brainstem evoked potential that mimics stimulus frequency. The FFRs to stimulation of one ear compared to the other are shown to have latency and amplitude dissimilarities, as well as considerable variations in waveform characteristics. The findings were obtained from eight subjects. Tone bursts at 500 Hz were ...

Vernier acuity is a form of hyperacuity in which the threshold offset between a test object and a reference object is smaller than the size of a foveal cone. Because the test and the reference objects usually have regular shapes (e.g. rectangular, triangular or circular), relatively few studies have addressed the role of shape information in determining hyperacuity thresholds. In this study, we...

Oscillations in neural activity play a critical role in neural computation and communication. There is intriguing new evidence that the nonsinusoidal features of the oscillatory waveforms may inform underlying physiological and pathophysiological characteristics. Time-domain waveform analysis approaches stand in contrast to traditional Fourier-based methods, which alter or destroy subtle wavefo...

xposure of a biological cell to an electric field can produce a variety of responses [1]-[6]. If the field strength exceeds a certain threshold value, this leads to a large transient increase in membrane conductivity and permeability for ions and molecules (electropermeabilization, often also named electroporation) or to fusion of adjacent cells (electrofusion) [5], [6]. Nowadays, these phenome...

BACKGROUND AND PURPOSE Neuromuscular electrical stimulation is used by physical therapists to improve muscle performance. Optimal forms of stimulation settings are yet to be determined, as are possible sex-related differences in responsiveness to electrical stimulation. The objectives of the study were: (1) to compare the ability of 3 different waveforms to generate isometric contractions of th...

The heating and impact of arc droplet acting on the weld pool lead to transfer mass, heat, momentum, which affects dynamic behavior microstructure in P-GMAW process. In this paper, an image processing program is used extract characteristics transition high-speed photography. influence current waveform pressure quantitatively analyzed with different parameters. under conditions are further studi...

We study infinitely repeated games with perfect monitoring and without public randomization devices. Both symmetric and asymmetric discounting cases are considered; a new geometric construct called “self-accessibility” is proposed and used to unify the analyses of these two cases. In the case of symmetric discounting, our approach delivers a constructive version of the folk theorem of Fudenberg...

Hyperactivation in mammalian sperm is characterized by a high-amplitude, asymmetric flagellar waveform. A mechanical advantage of this hyperactivated waveform has been hypothesized to be the promotion of flagellar detachment from oviductal epithelium. In order to investigate the dynamics of a free-swimming sperm׳s binding and escaping from a surface, we present an integrative model that couples...
