So far, pentazocine iontophoresis has never been studied, although pentazocine is widely used in pain management. The purpose of this study was to determine whether pentazocine transportation through a cellophane membrane could be enhanced using square-wave alternating current (AC) iontophoresis with an adjusted duty cycle and dependence on the voltage and the duty cycle. Voltages of 10, 25 and...

INTRODUCTION Many wireless systems are more and more present in daily life. More than 5 billions of people over the world are nowadays using devices emitting electromagnetic fields. This paper presents an analysis of the specific absorption rate (SAR) induced by an incident EM plane wave in different fetuses embedded in a homogeneous women model. Moreover, the influence of this homogeneity on t...

We demonstrate efficient generation of correlated photon pairs by spontaneous four wave mixing in a 5 μm radius silicon ring resonator in the telecom band around 1550 nm. By optically pumping our device with a 200 μW continuous wave laser, we obtain a pair generation rate of 0.2 MHz and demonstrate photon time correlations with a coincidence-to-accidental ratio as high as 250. The results are i...

This paper reports on the optical generation of a rapidly tunable millimeter-wave subcarrier for lidar–radar. The millimeter-wave signal is generated by beating the output from two Nd : YVO4/MgO : LiNbO3 electrooptical monomode microchip laser sections realized monolithically in a single composite crystal. The device has a continuous tuning range up to 45 GHz. The measured chirp rate is 3816 TH...

Under the sponsorship of the Defense Nuclear Agency, The Johns Hopkins University Applied Physics Laboratory investigated high-frequency ground wave propagation as a nuclear-survivable means of communication for land-mobile missile systems in Europe. Using a frequency band of 20 to 30 MHz and a portable, broadband, discone antenna, high-frequency ground wave propagation characteristics have bee...

A compact standing-wave linac has been designed using S-band microwaves for medical and industrial applications. It uses a bi-periodic structure with constant impedance. It consists of a buncher section with three-cells and on-axis coupled cavities with nine-cells. The total length is 740.0 mm including the electron gun. Using SUPERFISH, HFSS and PARMELA codes, it is capable to deliver 4.5 MeV ...

We review the properties of Galactic binaries containing two compact objects, as derived by means of population synthesis. Using this information we calculate the gravitational wave signal of these binaries. At frequencies below f <∼ 2 mHz the double white dwarf population forms an unresolved background for the low-frequency gravitational wave detector LISA. Above this limit some few thousand d...

The displacement- and frequency-noise-free interferometer (DFI) is a multiple laser interferometer array for gravitational-wave detection free from both the displacement noise of optics and laser frequency noise. So far, partial experimental demonstrations of the DFI have been done in 2D table top experiments. In this Letter, we report the complete demonstration of a 3D DFI. The DFI consists of...
