Modeling of glutamate-induced dynamical patterns.
Int J Neural Syst 19(6):395-407 (2009) PMID 20039463
We identify by chaos analysis a surprising possibility that muscarinergic receptors can help the system out of a chaotic regime.... -
Chaos-based mixed signal implementation of spiking neurons.
Int J Neural Syst 19(6):465-71 (2009) PMID 20039469
A new design of Spiking Neural Networks is proposed and fabricated using a 0.35 microm CMOS technology. The architecture is based on the use of both digital and analog circuitry. The digital circuitry is dedicated to the inter-neuron communication while the analog part implements the internal non-li... -
Mathematical study on ionic mechanism of lamprey central pattern generator model.
Int J Neural Syst 19(6):409-24 (2009) PMID 20039464
This paper studies the mechanisms of ionic channels in neurons of lamprey central pattern generator (CPG), such as the N-methyl-D-aspartate (NMDA) receptor channel and the calcium-dependent potassium channel etc. The CPG properties on oscillation attributed to the ionic mechanisms are exploited. The... -

Faster training using fusion of activation functions for feed forward neural networks.
Int J Neural Syst 19(6):437-48 (2009) PMID 20039466
We propose 'Fusion of Activation Functions' (FAF) in which different conventional activation functions (AFs) are combined to compute final activation. This has not been studied extensively yet. One of the sub goals of the paper is to check the role of linear AFs in combination. We investigate whethe... -
No-reference video quality measurement with support vector regression.
Int J Neural Syst 19(6):457-64 (2009) PMID 20039468
A novel approach for no-reference video quality measurement is proposed in this paper. Firstly, various feature extraction methods are used to quantify the quality of videos. Then, a support vector regression model is trained and adopted to predict unseen samples. Six different regression models are... -
The Role of Numeracy in Informed Consent for Surveys
J Empir Res Hum Res Ethics 4(4):17-26 (2009) PMID 19919316
If empirical estimates of disclosure risk are included in informed consent statements for surveys or other forms of research, participants must be able to understand the information provided. Using data from an online vignette-based experiment, this article explores the role that numeracy or quantit... -
Does switching between strategies within the same task involve a cost?
Br J Psychol 100(Pt 4):753-71 (2009) PMID 19239730
We discuss the extent to which current theories of task switching can account for these findings.... -
Modeling dynamic changes in type 1 diabetes progression: Quantifying $\beta$-cell variation after the appearance of islet-specific autoimmun...
Math Biosci Eng 6(4):753-778 (2009) PMID 19835428
We propose a mathematical model that takes into account the dynamics of functional and dysfunctional beta-cells, regulatory T cells, and pathogenic T cells. The model assumes that all individuals carrying susceptible HLA haplotypes will develop variable degrees of T1DM-related immunologic abnormalit... -
A mathematical model of weight change with adaptation.
Math Biosci Eng 6(4):873-87 (2009) PMID 19835433
