Abstract: A method for writing a Bragg grating in a rare-earth doped glass optical waveguide is provided. Ultrafast optical pulses are generated, preferably in the femtosecond range and having a writing wavelength in the range of 300 nm to 700 nm and an intensity sufficient to induce a change of refractive index in the rare-earth doped glass waveguide through densification. The optical pulses are diffracted using a phase mask, to generate an interference pattern having a pitch providing a fundamental Bragg resonance corresponding to the target wavelength to be reflected by the grating. The interference pattern is impinged on a region of the rare-earth doped glass waveguide, which is heated to a temperature above a threshold of about 350° C., for a predetermined heating period. Advantageously, the heating step allows the elimination of photodarkening effects which would otherwise be present in the waveguiding properties of the waveguide.

Abstract: A hydro-thermo irrigation mat (10) is comprised of a base sheet (11), a water-permeable root-shielding top sheet (12), and a capillary mat (15) of absorbent material therebetween. One or more flat pliable drip tapes (18) are loosely disposed in spaced-apart relationship between the top sheet (12) and the capillary mat (15). Hot water convection tubes (25) are disposed co-axially with the drip tapes (18) but between the base sheet (11) and the capillary mat (15). The drip tapes (18) are connected to a water supply line (22) and the hot water convection tubes (25) are secured to a hot water supply line (28). Water within the mat is heated and distributes heat from the hot water convection tubes (25) substantially throughout the mat.
Abstract: Reagents, methods and kits for screening for compounds that modulate the activity of voltage-gated sodium channels (NaV), such as human NaV1.5/SC-N5A/hH1 are described. The reagents, methods and kits are based on mutated NaV alpha subunit polyptides of SEQ ID NO:5 with mutations at positions 372, 898, 1419 and 1711 (the DEKA motif) and at positions 11485, 1486 and 1487 (the IFM motif) resulting in increased permeability for a group IIA divalent cation (Ca+) and decreased inactivation rate. The mutant polypeptide is used in a method and kit for determining whether a test compound modulates the channel activity, preferably using a chimeric polypeptide (chameleon polypeptide) comprising calmodulin, a calmodulin binding protein (M13), and two fluorescent agents.
Abstract: A GPS system for obtaining data from a GPS signal received at a plurality of antenna stations, each antenna station being connected to a common receiver station through an optical fiber link The system includes a light generating module at the receiver station generating an optical reference signal, and an antenna station module at each antenna station. The antenna station modules modulate the optical reference signal according to the GPS signal received, obtaining a twice modulated optical signal, and sending this signal to the receiver station. Finally, an output module is provided at the receiver station, this module being used for extracting the GPS signal and the oscillating reference signal, calibrating in real time the optical fiber links based on a phase comparison, and processing the GPS signal from the antenna stations, taking into account the real time calibration of the optical fiber links.

Abstract: A system and method for permanently writing diffraction gratings in low phonon energy glass waveguides are shown. Ultrashort light pulses are generated and made to form two beams synchronously superimposed in the waveguide, therefore forming an interference pattern corresponding to the desired grating. The light pulses are focussed so that the light intensity in the waveguide exceeds a filamentation threshold. The exposure of the waveguide to these light pulses is controlled temporally and spatially in order to limit detrimental thermal effects induced by the high-intensity pulses in the glass medium of the waveguide.

Abstract: The present invention relates to non-replicative recombinant retrovirus packaging cells able to grow in suspension in a serum-free medium. In particular, the present invention relates to a human embryonic 293SF-based cell line stably expressing gag and pol gene products from the murine Moloney leukemia virus (MLV) and either the feline RD114 env gene, the gibbon ape leukemia virus (GLV) env gene, or the amphotropic 4070Aenv gene. This particular combination allows the production of high titer of non-replicative retrovirus pseudotyped and prevents the recombination of plasmids. The recombinant retroviruses produced from these cells are safer and easier to produce for clinical use in gene therapy.
Abstract: Use of nicotine receptor agonists for treating inflammatory diseases, including a variety of pulmonary diseases. Such agonists have fewer side effects than other anti-inflammatory drugs, such as steroids. Moreover, these agonists can be used alone or in combination with other anti-inflammatory drugs to alleviate pulmonary diseases. For example, a method of treating pulmonary inflammation of an inflammatory disease selected from the group of asthma, interstitial pulmonary fibrosis (IPF), sarcoidosis, hypersensitivity pneumonitis (HP), and bronchiolitis obliterans with organizing pneumonitis (BOOP) in an animal in need thereof having said inflammation, including administering orally or by inhalation to said animal a nicotinic receptor agonist.
