Computerized binocular infrared pupillography was used to measure the transient pupillary light reflex (PLR) in both children with autism spectrum disorders (ASDs) and children with typical development. We found that participants with ASDs showed significantly longer PLR latency, smaller constriction amplitude and lower constriction velocity than children(More)
This paper is concerned with the finite-time stability problem of the delayed genetic regulatory networks GRNs with reaction-diffusion terms under Dirichlet boundary conditions. By constructing a Lyapunov–Krasovskii functional including quad-slope integrations, we establish delay-dependent finite-time stability criteria by employing the Wirtinger-type(More)
PURPOSE Contraction anisocoria describes a phenomenon in which the pupil of a directly illuminated eye constricts more than the pupil of the consensual (not illuminated) eye. The purpose of this study was to investigate the lateralization of contraction anisocoria in young female and male subjects. METHODS Infrared binocular pupillography was used to(More)
We investigated the gender effects on transient pupillary light reflex (PLR) in healthy young adults between 18 and 22 years old. Both dark-adapted and light-adapted PLRs were measured using green and red stimuli of different intensities. The results indicate that females had significantly larger relative constriction amplitudes than males in a dark-adapted(More)
A pupillary light reflex (PLR) model was proposed in this paper by considering the iris muscle mechanical properties and modulation inputs from both parasympathetic and sympathetic systems. The model can describe very well the experimental PLR responses induced by a short light flash of various intensities. In addition, an inverse method was developed to(More)
This paper is related to the problem of stability analysis for delayed genetic regulatory networks (DGRNs) with reaction-diffusion terms under Dirichlet boundary conditions. The nonlinear regulation function of DGRNs is assumed to be of the Hill form. By introducing novel integral terms in Lyapunov-Krasovskii functional and employing Wirtinger-type integral(More)
This paper focus is concerned with the finite-time state estimation problem for delayed reaction-diffusion genetic regulatory networks (DRDGRNs) under Dirichlet boundary conditions. The aim of this paper is to design a finite-time state observer which is used to estimate the concentrations of mRNAs and proteins via available measurement outputs. By(More)
This paper is concerned with the problem of the exponential passive filter design for neutral-type neural networks with time-varying mixed delays. First, a Luenberger-type filter is designed for estimating the network states. Second, by constructing an appropriate Lyapunov-Krasovskii functional and using the so-called Wirtinger-based integral inequality to(More)
We used optical imaging of intrinsic signals to study visual cortex responses in three mouse strains: wild-type (C57BL/6J), a strain with only rod function (cpfl1), and a strain with only cone function (rho(-/-)). A stationary flicker light stimulus with intensity ranging from 10(8.6) to 10(15.5) photons/cm2/s was used. We found that the intrinsic signal(More)
This paper is centered upon the state estimation for delayed genetic regulatory networks. Our aim is at estimating the concentrations of mRNAs and proteins by designing reduced-order and full-order state observers based on available network outputs. We introduce a Lyapunov-Krasovskii functional including quadruplicate integrals, and estimate its derivative(More)
