Abstract:

Entry of HIV-1 into target cells requires cell surface CD4 as well as additional host cell cofactors. A cofactor required for infection with virus adapted for growth in transformed T cell lines was recently identified and named fusin. Fusin, however, does not promote entry of macrophage-tropic viruses that are believed to be the key pathogenic strains in vivo. It has now been determined that the principal cofactor for entry mediated by the envelope glycoproteins of primary macrophage-tropic strains of HIV-1 is CC-CKR5, a receptor for the β-chemokines RANTES, MIP-1α, and MIP-1β.

Rong Liu - Miami FL, US

Assignee:

Scram Technologies, Inc. - Dunkirk MD

International Classification:

G02B 27/10

US Classification:

359629

Abstract:

An optical system for a digital light projection system is provided. The optical system comprises a plurality of LED arrays, wherein each LED array comprises a plurality of LEDs. The optical system also comprises an optical concentrator element positioned substantially adjacent to each of the LED arrays, wherein each concentrator element reflects light emitted from the plurality of LEDs within the corresponding LED array. The optical system preferably further comprises a reflective aperture element positioned substantially adjacent to the output surface of each concentrator element. The aperture element includes a reflective surface and an aperture defined by the reflective surface. The reflective surface faces the output surface of each corresponding concentrator element to thereby ultimately provide substantially uniform light which is projected through the aperture.

Assignee:

California Micro Devices - Milpitas CA

International Classification:

H03H 7/00

US Classification:

333176, 333167

Abstract:

The present invention relates to a low pass filter incorporating coupled inductors to enhance stop band attenuation. In one embodiment, the coupled inductors are provided along with various capacitors to provide for superior performance within a smaller surface area of a semiconductor or ceramic integrated device. In a further specific embodiment, the capacitors are formed on an integrated device within an area on which entirely intertwined inductors are formed. In another embodiment, at least one further pair of coupled inductors is included to create additional frequency attenuation notches, as well as a wide stop-band.

International Classification:

G03B 27/32
G03B 27/54

US Classification:

355 67, 355 77

Abstract:

An exposure apparatus for use in optical lithography can include a holder and a plurality of UV-LED modules carried by the holder and disposed in an array. A respective plurality of collimating lenses can be disposed in an array corresponding to the array of UV-LED modules. The plurality of UV-LED modules and the respective plurality of collimating lenses can provide a respective plurality of distinct beams of UV light. The plurality of collimating lenses may be spaced from the plurality of UV-LED modules and spaced from the exposure plane and have an optical configuration providing a composite beam of UV light formed from the plurality of distinct beams of UV light in which each beam inside the periphery of the array overlaps each adjacent beam by at least 70% at the exposure plane. A method for directing light onto an exposure plane in an optical lithography procedure is provided.

It has also been found that individuals who are homozygous for a mutation of the CKR-5 receptor are resistent to HIV infection; in vitro infection requires a 1000-fold higher dose of HIV than normal cells. The mutation results in complete suppression of CKR-5 expression.
