The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission has been collecting high-quality seismic data on Mars since early 2019 that provide the first direct observations of its interior structure. Here we report a complete analysis part marsquakes known as low-frequency events (main energy below 1 Hz) are sensitive to deep interior. To identify body-w...

Theta waves in the amygdala are known to be synchronized with theta waves in the hippocampus. Synchronization between amygdala and hippocampal theta waves is considered important for neuronal communication between these regions during the memory-retrieval process. These theta waves are also observed during rapid eye movement (REM) sleep. However, few studies have examined the mechanisms and fun...

In accordance with the energy conservation law, total of a closed physical system must remain constant at any moment time. The traveling elastic wave consists kinetic in oscillating particles medium and potential its deformation. existing theory waves, it is believed that densities without losses are same time vary according to law. Accordingly, density such different various time, only time-av...

A key consideration in physical modeling of seismic problems geotechnical engineering is the impact model container boundaries on soil layer response. The may alter stress-strain behavior from free-field conditions through possible reflection incident shear waves and generation P-waves within layers. In this study, 1-g shaking table experiments were performed to evaluate impacts boundary respon...

Background: There is a great concern for the possible adverse effects of cell phones’ microwaves. Contradictory results, however, have been reported for the effects of these waves on the body. In the present study, the effect of cell phone microwaves on sperm parameters and total antioxidant capacity was investigated with regard to the duration of exposure and the amount of the frequency of the...

In this work, the problem of Rayleigh wave propagation is considered in the context of the theory of thermoelastic diffusion. The formulation is applied to a homogeneous isotropic thermoelastic half space with mass diffusion at the stress free, isothermal, isoconcentrated boundary. Using the potential functions and harmonic wave solution, three coupled dilatational waves and a shear wave is obt...

Background & Aims:  The purpose of this study was to investigate the effects of land, warm and normal water aerobic exercises on heart rate variability in recovery period on healthy young men. Materials & Methods: In this study, subjects were randomly divided into four groups (control, Land aerobic exercise, normal water aerobic exercise, and warm water aerobic exercise) and performed reg...

Recently, methodologies for developing brain-computer interface (BCI) games using the BCI have been actively researched. The existing general framework for processing brain waves does not provide the functions required to develop BCI games. Thus, developing BCI games is difficult and requires a large amount of time. Effective BCI game development requires a BCI game framework. Therefore the BCI...
