Bures distance holds a special place among various measures due to its several distinguished features and finds applications in diverse problems quantum information theory. It is related fidelity and, other things, it serves as bona fide measure for quantifying the separability of states. In this work, we calculate exact analytical results mean root square between fixed density matrix random ma...

The sleep-onset period of 10 drug-free patients with narcolepsy-cataplexy and 10 normals matched for age and gender was investigated using the multiple sleep latency test to elicit episodes of intentional sleep onset. Spectral analyses were calculated for delta, theta, alpha, sigma, and beta frequencies using 5-second epochs beginning at lights-out and continuing until the first 2 minutes of st...

Methods. A population of horizontal visually guided saccades in a range of amplitudes from 1.5° to 30° was recorded by means of electro-oculography in eight normal adult subjects. The peak velocity-amplitude data of this population were fitted to four models: inverse linear, exponential, power law, and square root. To approximate the duration-amplitude relation, the square root was tested again...

We present a general analytical model for determining the location and pattern of wrinkles in thin membranes and for making preliminary estimates of their wavelength and amplitude. A rectangular membrane under simple shear and a square membrane subject to corner loads are analysed. In the first problem, our model predicts the wavelength and the wrinkle amplitude to be respectively inversely pro...

The objective of the present study was to investigate the strength of the three heads of triceps brachii muscle during handgrip force exercise with full elbow extension through surface electromyography. The myoelectric signals were recorded from the lateral, long and medial heads of triceps brachii muscle of 11 healthy men during maximal isometric contractions for 10-s of concurrent handgrip fo...

We establish the variational principle of Kolmogorov-PetrovskyPiskunov (KPP) front speeds in a one dimensional random drift which is a mean zero stationary ergodic process with mixing property and local Lipschitz continuity. To prove the variational principle, we use the path integral representation of solutions, hitting time and large deviation estimates of the associated stochastic flows. The...
