Several new methods for the digital discrimination of neutrons and gamma-rays in a mixed radiation field are presented. The methods introduced discriminate neutrons and gamma rays successfully in the digital domain. They are mathematically simple and exploit samples during the life time of the pulse, hence appropriate for field measurements. All these methods are applied to a set of mixed neutr...

Patient RP suffers a unilateral right homonymous quadrant anopia but demonstrates better than chance discrimination for stimuli presented in the blind field at temporal frequencies between 33 and 47Hz (all significant at p<.05, binomial). Examination of her reports of visual experience during blind-field discrimination suggests a more complex picture in which experiences particular to correct d...

Gamma oscillations are commonly observed in sensory brain structures, notably in the olfactory bulb. The mechanism by which gamma is generated in the awake rodent and its functional significance are still unclear. We combined pharmacological and genetic approaches in the awake mouse olfactory bulb to show that gamma oscillations required the synaptic interplay between excitatory output neurons ...

EPR spectra of alanine dosimeters irradiated by gamma-rays and alpha-particles were measured at different microwave power. The decomposed into three components corresponding to stable radiation-induced radicals. Different ratio the was obtained for gamma- alpha-irradiated alanine. observed effect can be used discrimination contribution alpha- gamma-radiation in mixed radiation field. That may u...

The scintillators capable of neutron detection are being the research hotspot recently. In this manuscript, we investigated possibility cerium-doped gadolinium aluminium gallium garnet (GAGG: Ce) crystal to achieve gamma discrimination through pulse shape (PSD) method. PSD is a method based on principle that waveforms scintillation light differ for different particles. experiments show it’s har...

Selective attention is an important filter for complex environments where distractions compete with signals. Attention increases both the gamma-band power of cortical local field potentials and the spike-field coherence within the receptive field of an attended object. However, the mechanisms by which gamma-band activity enhances, if at all, the encoding of input signals are not well understood...

Three analogues each of leucine and isoleucine carrying hydroxy groups in gamma- or delta- or gamma- and delta-position have been synthesized, and tested in the aminoacylation by leucyl-tRNA synthetases from E. coli and yeast. Hydrolytic proofreading, as proposed in the chemical proofreading model, of these analogues and of homocysteine should result in a lactonisation of these compounds and th...
