Abstract: A low noise amplifier device for receiving a radio frequency signal from a satellite contains an amplifier kept in a sealed chamber in a cryostat, and a cryogenic cooler mounted on the outside of the cryostat. The amplifier is: maintained in the sealed chamber attached to a cold finger of the cryogenic cooler, made of a material with good heat conductivity and without direct contact with the wall of the cryostat; connected to the input and output coupler, each traversing the wall of the cryostat; functional at room temperature and at least one cryogenic temperature well below room temperature; and the sealed chamber of the cryostat contains a gas at a pressure between a pressure close to the pressure outside the cryostat and 0.1 millibar.

Abstract: A radiofrequency amplifier includes a low noise amplifier (25) maintained in a hermetic cryostat structure (11) cooled by a cold head (30) and in which is maintained a low grade vacuum. The low noise amplifier receives signals from an input coupler (23) and transmits the signals through an output coupler (26). The input and output couplers are made, for a structural part, of a material with thermal conductivity equal or less than 50 W/m·K, and, for an electrically conductive part, of plating on at least one of the faces of the structural part, with a material with electrical conductivity more than 10E7 Siemens/m. The cold head includes at least two stages whose cold terminations are at different cryogenic temperatures, a base stage operating at a temperature close to the temperature at which the low noise amplifier must operate and at least one intermediate stage operating at an intermediate temperature.

Abstract: The present invention provides methods of treating rheumatoid arthritis. The methods generally involve an intermittent dosing strategy for administering Atiprimod alone or in combination with a second therapeutic agent wherein the second therapeutic agent is selected from the group consisting of Methotrexate, gold compounds, antimalarials, cyclosporine A, leflunomide, azathioprine, sulfasalazine d-penicillamine, aurothioglucose, auranofin, or a TNF inhibitor.

Abstract: A method of treatment of inflamed, pre-cancerous or cancerous tissue or polyps in a mammalian subject is disclosed. The treatment involves administration of a composition of at least one peptide agonist of a guanylate cyclase receptor and/or other small molecules that enhance intracellular production of cGMP. The at least one peptide agonist of a guanylate cyclase receptor may be administered either alone or in combination with an inhibitor of cGMP-dependent phosphodiesterase. The inhibitor may be a small molecule, peptide, protein or other compound that inhibits the degradation of cGMP. Without requiring a particular mechanism of action, this treatment may restore a healthy balance between proliferation and apoptosis in the subject's population of epithelial cells, and also suppress carcinogenesis.

Abstract: A data server for enabling the delivery of data information from any storage device containing said data and an external port requiring the data is disclosed. The server is comprised of a plurality of basic building blocks, each consisting of a first processing element connected to a second processing element via an inter-processing element bus to form a server plane. Each inter-processing element bus connects two processing elements in such a way that every processing element in a server plane is connected to every other processing element in the same server plane, via an independent inter-processing element bus. A plurality of sub-busses, each having input/output devices connected thereto are connected to the inter-processing element bus.

Abstract: Device for releasing a load from its support comprising two clamping jaws for the load, mounted inside a sleeve formed with openings and movable in relation to said sleeve under the combined action of the load and of a spring whose action is applied in the opposite direction to the load, between two positions, a lower position where the jaws are compulsorily closed and a higher position where the jaws can open due to the shape of the jaws and the position of the openings with means inhibiting the relative movement of said jaws in relation to said sleeve and driving means arranged so that it stops the action of said inhibiting means.
