OBJECTIVE To compare the histologic appearance of canine skin biopsies collected by use of a scalpel, skin biopsy punch, monopolar electrosurgery, CO2 laser, and radio wave radiosurgery in fully rectified wave form (RWRS). STUDY DESIGN Experimental, randomized design. ANIMALS Healthy adult grayhounds (n=4). METHODS Skin biopsies were collected using 5 techniques. Cut margins of biopsy spe...

[1] In order to make best use of the opportunities provided by space missions such as the Radiation Belt Storm Probes, we determine the response of complementary subionospheric radiowave propagation measurements (VLF), riometer absorption measurements, cosmic noise absorption, and GPS-produced total electron content (vTEC) to different energetic electron precipitation (EEP). We model the relati...

This work is aimed at simulating high quality sound fields for interactive 3D graphics applica-tions. We focused our efforts on three main problems: interactive calculation of sound occlusion byobstacles, integration of sound simulation in an interactive 3D animation system and adaptive simula-tion of sound reflections in reverberant environments. We first present an original me...

Though heterodyne detection provides a valuable technique for detecting small signals, the conventional system has several inherent disadvantages. In applications such as communications and radar, obtaining a reasonably high signal-to-noise ratio (SNR) requires (1) a good knowledge of the velocity of the transmitter or target, (2) a stable yet tunable local oscillator, and (3) a target or sourc...

1 HETERODYNE detection is a process which has been used in the radiowave, microwave, 1 and optical regions of the electromagnetic spectrum. Recently, the technique has been extended to the middle infrared as well [I-31. This paper discusses theoretical and experimental considerations related to the signal-to-noise ratio and the statistical nature of the coherently detected signal at the 10.6 pm...

PURPOSE Boron neutron capture therapy (BNCT) is a radiotherapeutic modality based on (10)B(n,alpha)(7)Li reaction, for the treatment of malignant gliomas. One of the main limitations for BNCT effectiveness is the insufficient intake of (10)B nuclei in the tumor cells. This work was aimed at investigating the use of L-DOPA as a putative enhancer for (10)B-drug 4-dihydroxy-borylphenylalanine (BPA...

—This study undertakes the theoretical design, CAD modeling, realization, and performance analysis of a microwave low-noise amplifier (LNA) which has been accurately developed for operation at 3.0 GHz (S-band). The objective of this research is to thoroughly analyze and develop a reliable microstrip LNA intended for a potential employment in wireless communication systems, and satellite applica...
