Rabbits were trained to discriminate between vertical and horizontal striations. After the 90% correct level had been reached transfer to vertical and horizontal rows of dots was studied. It was found that performance depended on the distance between adjacent dots. With angular dot separations (measured from the centers) larger than 4.9 degrees, performance was below the 75% correct level. This...

We study transport in ferromagnetic-superconductor/normal-metal systems. It is shown that charge and spin currents are pumped from ferromagnetic superconductors into adjacent normal metals by adiabatic changes in the order parameters induced by external electromagnetic fields. Spin and charge pumping identify the symmetry of the superconducting order parameter, e.g., singlet pairing or triplet ...

Three cases of male breast cancer were diagnosed among a small group of men who worked in a basement office of a multi-story office building. This office was adjacent to an electrical switchgear room which generated high magnetic fields in their work space. The risk of male breast cancer in this group was increased about 100-fold (observe three cases, expect 0.03 cases; P < 0.00001). Since 1991...

For decades, the standard of care for radiation treatment of early larynx cancers has been conventional treatment using opposed lateral fields encompassing the larynx and overlying neck structures, including the adjacent carotid arteries. The relative simplicity of the 3D technique and the excellent outcomes were shown in several series [1-4]. The ultimate local control is even higher if we tak...

Abstract Fresnel diffraction dominated fields propagating at glancing angles in a wide planar and rectangular optical waveguides are considered. Both schemes are characterized numerically with multi-harmonic interaction. Resonant effect in terms of the energy gain versus geometry parameter is demonstrated. It is found that adjacent harmonics play a dominant role in the performance at short wave...

The paper faces the challenge to generalize existing trends and approaches in the field of artificial intelligence. Under consideration are expert systems, dynamic neural networks, probabilistic reasoning, fuzzy logic, genetic algorithms, multi-agent systems, bio-inspired algorithms, distributed nonlinear computing, chaos-driven pattern recognition. Each approach strengths and limitations are s...

AIT, a system for putting a small “Aircraft Identification Tag” onto the voice communication between pilots and controller was presented in [4]. The system is based on spread-spectrum watermarking techniques and consists of an encoder, an autonomous data acquisition module and a decoder. In this PhD study the future research aims for major improvements in data capacity, inaudibility, reliabilit...

Regular-shaped metal nanocrystals and their ensembles can serve as ideal substrates for studying surface-enhanced Raman scattering (SERS). We synthesized well-defined silver nanowires for a systematic study of SERS signal with respect to polarization and structural ordering. The observed dependence on polarization direction confirms prior theoretical predictions that large electromagnetic (EM) ...

We report the observation of resonant tunneling effects a t high applied fields in a multiple quantum-well P-I-N diode. The A10,81no,5,As/Gao,4,1no,53As structure shows features in the dark current due to Zener tunneling of electrons from the lowest sub-band in a valence-band quantum well to the first and second sub-bands of an adjacent conduction-band well.

Plasmodium vivax malaria resistant to chloroquine is alarming in Indonesia and has been also reported in other countries. An alternative drug is needed. The study was a prospective evaluation and a comparative study of the therapeutic efficacy of chloroquine 25 mg base/ kg bw for 3 days(CQ3, n=75), CQ3 plus sulfadoxine-pyrimethamine based on pyrimethamine dosage of 1.25 mg/kg bw single dose (SP...
