Terahertz (THz) technology is promising in several applications such as imaging, spectroscopy and communications. Among methods the generation detection of THz waves, a time-domain system that developed using photoconductive antennas (PCA) emitter detector presents advantages simple alignment, low cost, high performance etc. In this work, we report design, fabrication characterization 2-D PCA a...

A method is presented that allows one to estimate transmitter release rates from fluctuations of postsynaptic current records under conditions of stationary or slowly varying release. For experimental applications, we used the calyx of Held, a glutamatergic synapse, in which "residual current," i.e., current attributable to residual glutamate in the synaptic cleft, is present. For a characteriz...

In this study, dynamic centrifugal model tests for two homogeneous saturated soft clay sites are designed to analyze the influence of overlying sea water on ground motion. We obtain response spectrum value and amplification coefficient from acceleration sensor records. Through comparative analysis, we conclude that with increase in input peak motion, at same depth gradually increases. When is s...

To investigate sensory reweighting as a fundamental property of sensor fusion during standing, we probed postural control with simultaneous rotations of the visual scene and surface of support. Nineteen subjects were presented with pseudo-random pitch rotations of visual scene and platform at the ankle to test for amplitude dependencies in the following conditions: low amplitude vision: high am...

Abstract. Sudden stratospheric warmings (SSWs) are major disruptions of the Northern Hemisphere (NH) polar vortex and occur on average approximately six times per decade in observation-based records. However, within these records, intervals significantly higher lower SSW rates observed, suggesting possibility low-frequency variations event occurrence. A better understanding factors that influen...

The representation of the human electroencephalogram (EEG) records by neurophysiologists demands standardized time-amplitude scales for their correct conventional interpretation. In a suite of graphical experiments involving scaling affine transformations we have been able to convert electroencephalogram samples corresponding to any particular sleep phase and relaxed wakefulness into each other...

The oxygen isotopic composition of a banded coral from the western equatorial Indian Ocean provides a 150-year-long history of the relation between the El Niño–Southern Oscillation (ENSO) phenomenon and the Asian monsoon. Interannual cycles in the coral time series were found to correlate with Pacific coral and instrumental climate records, suggesting a consistent linkage across ocean basins, d...

BACKGROUND The achievement of quality of care constitutes a priority for modern health care systems. The objective of our study was to evaluate a quality improvement intervention in primary care of Cyprus. METHODS In a two-arm non-randomized controlled study in primary care centres in Cyprus, all patients with hypertension (HTN) and diabetes (n = 539) were invited. In one urban and one rural ...
