A staple line buttress material having an adhesive surface, packaged and provided in sterile, ready-to-use form. The material can be used to retrofit surgical staplers to provide an improved staple line, and with improved ease of use.

A corrosion resistant component of semiconductor processing equipment such as a plasma chamber includes a diamond containing surface and process for manufacture thereof.

A method of suppressing the etch rate for exposed silicon-and-nitrogen-containing material on patterned heterogeneous structures is described and includes a two stage remote plasma etch. The etch selectivity of silicon relative to silicon nitride and other silicon-and-nitrogen-containing material is increased using the method. The first stage of the remote plasma etch reacts plasma effluents with the patterned heterogeneous structures to form protective solid by-product on the silicon-and-nitrogen-containing material. The plasma effluents of the first stage are formed from a remote plasma of a combination of precursors, including nitrogen trifluoride and hydrogen (H₂). The second stage of the remote plasma etch also reacts plasma effluents with the patterned heterogeneous structures to selectively remove material which lacks the protective solid by-product. The plasma effluents of the second stage are formed from a remote plasma of a fluorine-containing precursor.

Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymers are made by use of fast, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled way to rapidly and precisely build dendritic structures, generation by generation, with cleaner chemistry, often single products, lower excesses of reagents, lower levels of dilution, higher capacity method, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The dendritic compositions prepared have novel internal functionality, greater stability (e.g., thermal stability and less or no reverse Michael's reaction), and reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of polyfunctional branch cell reagents with polyfunctional cores do not create cross-linked materials. Such dendritic polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, polymers, nanoscale monomers, calibration standards for electron microscopy, making size selective membranes, and agents for modifying viscosity in aqueous formulations such as paint. When these dendritic polymers have a carried material associated with their surface and/or interior, then these dendritic polymers have additional properties for carrying materials due to the unique characteristics of the dendritic polymer, such as for drug delivery, transfection, and diagnostics.

Disclosed are improved polymer materials. Also disclosed are fine fiber materials that can be made from the improved polymeric materials in the form of microfiber and nanofiber structures. The microfiber and nanofiber structures can be used in a variety of useful applications including the formation of filter materials.

An entropy encoding/decoding scheme uses an arithmetic encoder/decoder together with a context modeler for performing a context-based adaptive binary arithmetic coding, which is especially suited for video compression applications. The context modeler includes an initializer for initializing the context modeler by determining and providing initialization probability information to the arithmetic encoder, the initialization probability information to be used by the arithmetic encoder for processing a start symbol of a symbol sequence. The initializer is operative to determine the initialization probability information based on an estimation of the symbol statistics relating to the start symbol such that an initialization probability distribution is different from an equi-probable distribution for all symbols of the symbol set. By means of the initialization, the context-based adaptive binary arithmetic coding/decoding scheme is optimally adjusted before processing a start symbol of the symbol sequence so that no bit rate compression losses because of a delayed context-based adaptation are introduced.

An LED array surface-mounted on a circuit board and applied to a cooling member, such that any generated heat is optimally eliminated. The cooling member can be in any desired shape so that motor vehicle lights, such as blinkers, can be adapted to the outside contour of the vehicle. For a rotating light, the circuit board can be applied around a cooling member fashioned as a hollow cylindrical member which is adapted to rotate.
