The present invention is directed to an expandable spinal fusion intervertebral implant that provides for maintaining and creating lordosis in the human spine that can be filled with biologics while in situ to encourage spinal fusion. A threaded rod that traverses an insertion / injection handle can be rotated to operate a screw within the interbody cage that displaces opposing vertical tapped sliding wedges, causing them to converge towards each other. Such contact causes the operation of a horizontal wedge that acts as a lift to expand the interbody cage to one of various dimensions in a preferred range. At its desired expansion, the spinal fusion implant of the present invention is sized to fit within the disc space between two vertebral bodies and fill all voids left while the vertical and horizontal wedges operate within, due to the biologics being contained within the interbody cage.

A process and system which improves the capacity and efficiency of a power plant. A LNG supply system fuels the plant. Gasified LNG in a combustor mixes with the air from an air compressor to provide the hot combustion gas for a gas turbine. The expanding LNG is used to chill a heat exchange fluid, e.g. water, which heat exchange fluid cools and densifies the intake air for the air compressor. Subsequently, the heat exchange fluid is used in another heat exchange step and is then re-chilled and recycled to cool and densify the intake air.

Metallic stents which have a randomly oriented microstructure, and possess quasi-isotropic mechanical and physical properties are disclosed. The novel stents can be “tailor-made” to mimic the geometry of the blood vessel(s) at the deployment site and can be designed to treat coronary artery disease at the point where blood vessels branch. The metallic materials of choice are ductile, corrosion resistant and exhibit little crystallographic texture. The novel stents can be produced from a metallic precursor which is quasi-isotropic and exhibits little texture by processing means, such as machining, which do not reintroduce texture. Alternatively, quasi-isotropic and low texture stents are achieved by suitable post-processing of conventionally fabricated stent materials.

The present invention is directed to an expandable spinal fusion intervertebral implant and a method for surgically implanting said implant that provides for maintaining and creating lordosis in the human spine that can be filled with biologics while in situ to encourage spinal fusion. A threaded rod that traverses an insertion / injection handle can be rotated to operate a screw within the interbody cage that displaces opposing vertical tapped sliding wedges, causing them to converge towards each other. Such contact causes the operation of a horizontal wedge that acts as a lift to expand the interbody cage to one of various dimensions in a preferred range. In its expanded height, the overall length of the interbody cage is maintained. At its desired expansion, the spinal fusion implant of the present invention is sized to fit within the disc space between two vertebral bodies and fill all voids left while the vertical and horizontal wedges operate within, due to the biologics being contained within the interbody cage.

A method for recovery of lost and / or corrupted data transmitted from a transmitter device to a receiver device. The data is coded by an encoder connected to the transmitter device. The data is transmitted from the transmitter device to the receiver device via a transmission system and is decoded by means of a decoder connected to the receiver device. This is performed through application of a low density parity check method, wherein lost and / or corrupted data is restored during decoding. The decoding is performed by solving the equation system of the parity check matrix H. The parity check matrix H is brought into a triangular form by column and / or row permutations. Columns of a sub-matrix B of the matrix H which impede the triangulation process are shifted into a sub-matrix P of the matrix H so that the triangulation process can be continued until the matrix H except for the sub-matrix P has been completely brought into a triangular form. The Gaussian elimination method is applied to a part of the sub-matrix P. The selection of the column or columns of the sub-matrix B which are to be shifted into the sub-matrix P is performed on the basis of the weight of the column which corresponds to the number of non-zero-entries in the column, and / or on the basis of the weight of the rows of the sub-matrix B connected to the column.
