PURPOSE To analyze cone and rod phototransduction parameters from ERG a-waves in patients with RP and to determine the relationships among these parameters, age, and mode of inheritance. METHODS Sets of four white flashes (3.2-4.4 log scotopic troland [scot td-s]) were presented in the dark. The same stimuli were later presented against a rod-saturating background and the generated cone a-wav...

It is recognized both experimentally and computationally that the main damage of divertor in fusion devices such as ITER could be due to melting of metallic plasma facing components such as tungsten developed during plasma instabilities. Macroscopic melt motion and splashing with ejection of molten droplets into plasma are major concern. The computational modelling of uncoupled/coupled plasma–m...

We calculate the average transmission for sand p-polarized electromagnetic ~EM! waves and consequently the localization length of two-dimensional ~2D! disordered systems which are periodic on the average; the periodic systems form a square lattice consisting of infinitely long cylinders parallel to each other and embedded in a different dielectric medium. In particular, we study the dependence ...

A spectrum of weakly guided waves in the solar atmosphere at frequencies as high as 100 mHz (10 s period) has been detected with high-cadence solar image sequences from the Transition Region and Coronal Explorer (TRACE) spacecraft. The waves are visible in the TRACE 1600 far-UV passband and were detected as faint Å ridges in an energy spectrum produced by Fourier transformation of subfields of ...

Cone electroretinograms (ERGs) in response to different color flashes were examined using a Ganzfeld stimulus in 19 eyes after successful retinal detachment surgery. In the operated eyes, the short wavelength sensitive (S-) cone b-wave was reduced more than the mixed long (L-) and middle (M-) wavelength sensitive cone b-waves. The ratio of the S-cone ERG b-wave amplitude between operated eyes a...

The high-order harmonic-wave generation of ultrasonic shear waves has not yet been studied. We generated high-order shear harmonic waves and studied them in terms of the nonlinear wave mechanism associated with strain waves. When the shear waves propagated through highly dissipative MnCu20Ni5Fe2, TiNi, and Sn-3Al specimens and were reflected from the far side of the specimen, we observed high-o...

Background Due to the advancement of technology and communication, mobile and Wi-Fi have become as an integral part of human life, particularly young population. Thus, a review of EM wave’s effects on the reproductive health has become one of the critical matters of researches in medical field. The accession of using Wi-Fi around the world now has made it possible that about 450 million family ...

Correlation of the coda of large earthquakes can be used to retrieve body waves at teleseismic distances. This retrieval depends on waves propagating with equal energy in all directions (equipartitioning). We carry out a beamforming analysis of body waves at periods of 10 and 40 s recorded at USArray and show that the late coda, up to 10 h after the Okhotsk earthquake, is dominated by waves pro...

The main focus of this study is to develop an efficient frequency-wavenumber code to synthesize high-frequency (say, 10 Hz) regional seismograms (up to a distance of more than 1000 km) in a medium consisting of a large number of crustal layers, and investigate effects of regional waveguides on L, waves. In this newly developed code, the frequency-wavenumber response is evaluated by using the Fi...

In the classic microseismic band of 5-20 s seismic noise consists mainly of fundamental mode Rayleigh and Love waves; however, at shorter periods seismic noise also contains a significant amount of body wave energy and higher-mode surface waves. In this study we perform a global survey of Earth’s short period seismic noise field with the goal of quantifying the relative contributions of these p...
