Coincidence Detector Properties of Small Networks of Interneurons
2007We study the transmission of excitatory synaptic inputs by a network of interneurons, coupled by electrical and inhibitory synapses, in the cases in which the network consists of three and four coupled units. It is shown that in both cases the network behaves as a coincidence detector.

On the timing properties of Ge detectors
Nuclear Instruments and Methods in Physics Research, 1982The timing properties of an intrinsic Ge detector with a surface of 19 cm2 and of a 70 cm3 Ge(Li) diode have been studied. The dependence of the timing signals of each detector on the γ-ray energy has been tested with a 60Co source, whereby a conversion into X-rays of appropriate converters was used for Eγ < 115 keV.

Investigation of the properties of an optothermal detector
Soviet Journal of Quantum Electronics, 1978An optothermal detector with a pyroelectric sensitive element is described. Estimates are given of the limits of applicability of this device and its performance compared with the spectrophone. The dependences of the absorption coefficient of formaldehyde CH2O on its pressure and that of the buffer gas, determined experimentally at the P12–11 (17) CO ...

Property detectors for bursts and transitions in speech perception
The Journal of the Acoustical Society of America, 1977A series of adaptation experiments was conducted to investigate the role of initial noise bursts and transitions as cues to place of articulation in stop consonants. A test continuum was constructed consisting of 14 synthetic stimuli in which the transitions of formant two and formant three were systematically varied to range along the [b d g] phonetic

Simulation of the collection properties of CdTe strip detectors
IEEE Transactions on Nuclear Science, 2001CdTe is an attractive material for X-ray and gamma-ray detectors, but the poor transport properties of holes affect the performance by introducing a low energy tailing in the observed spectra. A possible solution to this problem is to optimize the electrode geometry, for example, by reducing the dimension of the anode with respect to the cathode.

Properties of feature detectors for VOT
The Journal of the Acoustical Society of America, 1976Certain properties of a feature detector system sensitive to VOT were investigated with a binaural adaptation-dichotic testing paradigm. On each dichotic test trial, a nonboundary voiced stop was paired with one of a set of voiceless stops. The voiceless stops varied in VOT, from values close to the phonetic boundary to values well within the voiceless

Properties of a Light-Modified-Breakdown Detector in GaAs
Applied Optics, 1973The properties of a bulk-effect millimeter-wave detector made from high-purity epitaxial GaAs are discussed. The devices are operated at 4.2 K in a new light-modified-breakdown (LMB) mode with dc bias above avalanche breakdown. When operated in the LMB mode as a direct video detector, circuit-limited response time (10-90% pulse) less than 20 nsec is ...

A differentiation / enhancement edge detector and its properties
IEEE Transactions on Systems, Man, and Cybernetics, 1985A differentiation/enhancement edge detector for noisy situations is proposed. The definition of the gradient has been initiated from the algorithm for finding a border in a binary picture. The advantages of this operator have been compared with those of other widely used operators. A measurement of error in extracting edges by thresholding the gradient

Properties of indium antimonide detectors for use as transfer standards for detector calibrations
Applied Optics, 1998The properties of 4-mm-diameter and 7-mm-diameter liquid-nitrogen-cooled indium antimonide detectors were investigated to determine their suitability as transfer standards (i.e., reference detectors) for the detector calibration facility at the National Research Council of Canada.
