Abstract: An optical coherence tomography (OCT) imager comprising: a low coherence light source that provides light; a photosensor for imaging light; optics that directs a first portion of the light along a first optical path so that it is imaged on the photosensor and a second portion of the light along a second optical path so that it is reflected by material in the target to the photosensor where it is imaged to interfere with light from the first portion to form an interference pattern; and a mask through which light from at least one of the first and second portions of light passes that generates a relative phase perturbation between portions of light that passes through it.

Abstract: We disclose a system for preparing antimicrobial fabrics, coated with metal oxide nanoparticles by means of a novel sonochemical method. These antibacterial fabrics are widely used for production of outdoor clothes, under-wear, bed-linen, bandages, etc. The deposition of metal oxides known to possess antimicrobial activity, namely ZnO, MgO and CuO, can significantly extent the applications of textile fabrics and prolong the period of their use. By means of the novel sonochemical method disclosed here, uniform deposition of metal oxide nanoparticles is achieved simply.

Abstract: A solar energy conversion system is presented. The system comprises at least one waveguide arrangement having at least one light input respectively. The waveguide arrangement comprises a core unit for passing input solar radiation therethrough and a cladding material arrangement interfacing with the core therealong. The cladding material arrangement is configured as an array of spaced-apart solar cells arranged along the core unit and having different optical absorption ranges, such that an interface between the waveguide core and the cladding arrangement spectrally splits the photons of the input solar radiation by causing the photons of different wavelengths, while passing through the core unit, to be successively absorbed and thereby converted into electricity by the successive solar cells of said array.

Abstract: The invention relates to nickel-cobalt alloys as current collectors and conductive interconnects, and to methods of deposition thereof on transparent conductive oxides. The invention further relates to transparent conductive oxides on which a nickel-cobalt alloy is deposited and to electrodes made of such transparent conductive oxides for photochemical applications, in particular, for dye-sensitized solar cells (DSSCs).
Abstract: The invention relates to production of maladapted animals characterized by PTSD like behavior from a population by behavioral conditioning. The method includes determining a baseline behavioral level for individual under defined conditions; exposing each individual animal to trauma event and further determining a posttraumatic event behavioral level; re-exposing each individual to a trauma related event and further determining an individual post trauma related event behavioral level and evaluating the individual post trauma related event behavioral level for each individual animal with respect to a baseline value according to a predetermined rule in order to determine which individuals are maladapted animals characterized by PTSD like behavior. Use of the method for assaying efficacy of PTSD treatment is within the scope of the invention, as are animals produced by claimed methods. Once the method is established, biological parameters may be employed in addition to, or in lieu of behavioral parameters.

Abstract: A device for use in optical signal control is presented. The device comprises an amplification waveguide, including a pumpable medium, and a reference and a control inputs and an output selectively allowing transmission of light respectively into and out of said amplification waveguide. The reference input, the amplification waveguide and the output define together a transmission scheme for reference light through the pumpable medium. The control input and the amplification waveguide define a depletion scheme for the pumpable medium and control light. The device thus allows for controlling an output signal, formed by the transmission of the reference light, by controllable depletion of the pumpable medium.

Abstract: A current limiting device (30, 40, 50, 60) comprising for each phase of an AC supply a closed magnetic core (31) of reduced volume and mass having first and second pairs of opposing limbs (32a, 32b; 33a, 33b), and at least one AC coil (35a, 35b) enclosing opposing limbs (33a, 33b) of the magnetic core (31) and adapted for series connection with a load. A superconducting DC bias coil (34) encloses a limb) (32a, 32b) of the magnetic core (31) for saturating each of the opposing limbs (33a, 33b) in opposite directions by the bias coil (34). Under fault conditions, the AC flux in at least one limb counteracts the DC bias flux, bringing the limb out of saturation. Preferably, current is reduced in the DC bias coils thus bringing both opposing limbs of the core out of saturation.
