Spiking Neural P(SN P) system with anti-spikes uses two types of objects called spikes and anti-spikes which can encode binary digits in a natural way. We propose a formal method based on Petri nets, which provides a natural and powerful framework to formalize SN P systems with anti-spikes. This enables the use of existing tools for Petri nets to study the computability and behavioural properti...

Background: Female sexual dysfunction(FSD) is defined as sexual desire disorders,sexual Arousal disorders,orgasmic disorders and sexual pain disorders that result from anatomical,physiological ,medical and psychological multiple factors and cause personal severe discomfortibility and affect quality of life and relationship between individuals. The aim of this study is to compare the prevalence ...

BACKGROUND We aimed to determine whether children conceived with ovarian stimulation alone (OS(A)) would differ phenotypically and biochemically from naturally conceived children of fertile and subfertile parents. METHODS Healthy pre-pubertal children aged 3-10 years, born at term, after singleton pregnancies were recruited in Auckland (New Zealand) and were allocated into three groups: (i) c...

This paper presents a new time-frequency based EEG seizure detection method. This method uses the distribution of interspike intervals as a criterion for discriminating between seizure and nonseizure activities. To detect spikes in the EEG, the signal is mapped into the time-frequency domain. The high instantaneous energy of spikes is reflected as a localized energy in time-frequency domain. Hi...

Broadband transient absorption (TA) spectroscopy, three-pulse photon echo peak shift (3PEPS), and anisotropy decay measurements were used to study the solvation dynamics in bulk water and interfacial water at ZrO(2) surfaces, using Eosin Y as a probe. The 3PEPS results show a multiexponential behavior with two subpicosecond components that are similar in bulk and interfacial water, while a thir...

BACKGROUND The cost-benefit of raccoon rabies control strategies such as oral rabies vaccination (ORV) are under evaluation. As an initial quantification of the potential cost savings for a control program, the collection of selected rabies cost data was pilot tested for five counties in New York State (NYS) in a three-year period. METHODS Rabies costs reported to NYS from the study counties ...

The computational repertoire of neurons is enhanced by regenerative electrical signals initiated in dendrites. These events, referred to as dendritic spikes, can act as cell-intrinsic amplifiers of synaptic input. Among these signals, dendritic NMDA spikes are of interest in light of their correlation with synaptic LTP induction. Because it is not possible to block NMDA spikes pharmacologically...

The performance of a method for sorting of waveforms in multi-neuron data (Gädicke and Albus, 1995) is evaluated by using artificial spike patterns generated by the computer and by adding to these spikes noise or free running sine waves of varying frequency and amplitude to simulate EEG-waves. The DSP32C is capable of continuously processing spikes at 183.106 Hz. In addition to real-time sortin...
