Changes in rod increment threshold at the center of a desensitizing background disc were measured. Sensitization by an annular surround was shown to depend more upon the surround’s effects on cones than on rods. This demonstrates a rod-cone interaction in which the activation of cones in the vicinity of a test flash influences the detection of that flash h.r rods.

B-wave increment threshold experiments in the rat show that "rod saturation" occurs at different background levels with different anesthetics. Rod saturation builds up over the first 60 sec of light adaptation in pentobarbital anesthetized but not in urethane anesthetized animals. These and other findings suggest that "rod saturation" can occur when the rod photoreceptors themselves are not sat...

Automated attendance management system using face recognition is a smart way of marking attendance which is more secure and time efficient as compared to already existing attendance systems. In our work we propose an automated attendance management system. This system automatically detects the student when he enters the class room and marks the attendance by recognizing his face. A threshold va...

A rise in seizure threshold during a course of electroconvulsive therapy (ECT) has been demonstrated in patients with depression and mania, but no information has been available as to whether the same result occurs in schizophrenia. Ninety-three patients with schizophrenia underwent estimation of the seizure threshold by the dose-titration method, at the first and second, seventh, fourteenth, a...

A threshold counter is a shared data structure that assumes integer v ues. It provides two operations: Increment changes the current counter val from v to v+1, while Read returns the value bv=wc, where v is the curre counter value and w is a fixed constant. Thus, the Read operation retur the “approximate” value of the counter to within the constant w. Thresho counters have many potential uses, ...

For the free vibrations of multi-degree mechanical structures appeared in structural dynamics, we solve quadratic eigenvalue problem either by linearizing it to a generalized or directly treating developing iterative detection methods for real and complex eigenvalues. To problem, impose nonzero exciting vector into eigen-equation, nonhomogeneous linear system obtain response curve, which consis...

We measured increment-threshold spectral sensitivity functions during saccades, immediately after saccades and during fixation. A uniform white background field which covered observer's whole visual field prevented any retinal masking effects. Visual sensitivity was degraded during saccades or after saccades. The reduction in sensitivity depended upon the wavelength of the test stimulus. The sp...

A novel uncalibrated CMOS programmable temperature switch with high temperature accuracy is presented. Its threshold temperature Tth can be programmed by adjusting the ratios of width and length of the transistors. The operating principles of the temperature switch circuit is theoretically explained. A floating gate neural MOS circuit is designed to compensate automatically the threshold temper...

Lasing conditions in a dye-doped cholesteric liquid crystal ~ChLC! have been studied in view of optical modes for the light propagating in ChLCs using a polymeric dye with the transition dipole moment parallel to the local director of the ChLC host. We found that lasing always occurs at the lower-energy edge of the photonic gap. This is because that the optical eigen mode at the lower-energy ga...

The so-called ”acoustic revival mechanism” of core-collapse supernova proposed recently by the Arizona group is an interesting new possibility. Aiming to understand the elementary processes involved in the mechanism, we have calculated the eigen frequencies and eigen functions for the g-mode oscillations of a non-rotating proto neutron star. The g-modes have relatively small eigen frequencies. ...
