INTRODUCTION The aim of this preliminary report is to demonstrate the efficacy of rapid transcranial magnetic stimulation (rTMS) in the treatment of relapsed major depressive disorder (MDD) patients. METHODS Four patients with major depressive disorder who were successfully treated with rTMS received a second course of rTMS treatment. Patients were(More)
In the past decade it became customary to relate the probability of appearance of extremely steep (the so-called freak, or rogue waves) to the value of the Benjamin-Feir Index (BFI) that represents the ratio of wave nonlinear-ity to the spectral width. This ratio appears naturally in the cubic Schrödinger equation that describes evolution of uni-directional(More)
We observe the propagation dynamics of surface gravity water waves, having an Airy function envelope, in both the linear and the nonlinear regimes. In the linear regime, the shape of the envelope is preserved while propagating in an 18-m water tank, despite the inherent dispersion of the wave packet. The Airy wave function can propagate at a velocity that(More)
—The problem of obtaining quantitative data on spatial ocean wave spectra from the images of the ocean surface by either regular SAR or along-track interferometric SAR (INSAR) is studied. The dominant mechanism which allows imaging of ocean waves by SAR/INSAR is the so-called velocity bunch-ing. This mechanism is essentially nonlinear. The theoretical(More)
We demonstrate both theoretically and experimentally propagation dynamics of surface gravity water-wave pulses, having Hermite-Gauss envelopes. We show that these waves propagate self-similarly along an 18-m wave tank, preserving their general Hermite-Gauss envelopes in both the linear and the nonlinear regimes. The measured surface elevation wave groups(More)
A sequential model which describes the kinetic behavior of multilayer immobilized-enzyme filter reactors for systems obeying the Michaelis-Menten scheme and various types of inhibition by product and by substrate is proposed. The model was varified experimentaly using a single enzyme-filter-substrate system-urease bound to nylon-filter disks acting on(More)
We report on the theoretical and experimental study of the generation of propagating waveguide modes on the water surface. These propagating modes are modulated in the transverse direction in a manner that satisfies boundary conditions on the walls of the water tank. It is shown that the propagating modes possess both anomalous and normal dispersion(More)
Most operable Laser Doppler Anemometry (LDA) systems employ the fringe mode geometrical configuration with a counting type signal processor. The fringes are contained within an ellipsoid volume, which is commonly described as the sensing volume of the LDA. Generally, the dimensions of the focusing volume are determined from the waist diameter of the beams(More)
Urease was bound to commercially available nonwoven nylon fabric filters. Multilayer immobilized-enzyme filter reactors were constructed by packing varying numbers of urease-nylon filters in a column. Owing to the relatively open structure and high mechanical strength of the filter fabric, compaction and pressure drop effects were minimal. The reactors(More)
