-An artificial network is described that can learn, recognize, and generate higher-order temporalspatial sequences. It consists of three parts: (1) comparator units, (2) a parallel array of artificial neural networks that are derived from the visual-vestibular networks of the snail Hermissenda. as well as hippocampal neuroanatomy, and (3) delayed feedback lines from the output of the system to ...

background: noise is defined as unwanted or meaningless sound that apart from auditory adverse health effects may distract attention from cues that are important for task performance. human performance is influenced by many job-related factors and workplace conditions including noise level. objective: to study the effect of noise on human performance. methods: the participants included 40 healt...

‎Let $G$ be a finite group‎. ‎An element $gin G$ is called non-vanishing‎, ‎if for‎ ‎every irreducible complex character $chi$ of $G$‎, ‎$chi(g)neq 0$‎. ‎The bi-Cayley graph ${rm BCay}(G,T)$ of $G$ with respect to a subset $Tsubseteq G$‎, ‎is an undirected graph with‎ ‎vertex set $Gtimes{1,2}$ and edge set ${{(x,1),(tx,2)}mid xin G‎, ‎ tin T}$‎. ‎Let ${rm nv}(G)$ be the set‎ ‎of all non-vanishi...

Infection with gastrointestinal nematodes (GIN), particularly Haemonchus contortus, is the biggest constraint to profitable goat production in the United States (US). Due to widespread prevalence of anthelmintic resistance in goat GIN, alternative, non-chemical control methodologies are needed to increase profitability of small ruminant industries. A study was designed to test the efficacy of a...

The neocortex contains multiple types of inhibitory neurons whose properties suggest they may play different roles within the cortical circuit. By recording from three cell types during two distinct network states (UP and DOWN states) in vitro, we were able to quantify differences in firing characteristics between these cells during different network regimes. We recorded from regular-spiking (R...

Logarithmic gaps have been used in order to find a periodic component of the sequence of prime numbers, hidden by a random noise stochastic or chaotic . It is shown that multiplicative nature of the noise is the main reason for the successful application of the logarithmic gaps transforming the multiplicative noise into an additive one. A relation of this phenomenon to spontaneous neuron activi...

Temporal, spectral, and combined temporal-spectral resolution of hearing was assessed by recording masked hearing thresholds. The masker was an octave band noise. Spectral resolution was assessed by introducing a spectral gap of half an octave bandwidth in the masker. A 50-msec gap assessed temporal resolution. The spectral and temporal gaps were used separately or simultaneously. Normal-hearin...
