Abstract: A downhole tool having a body or structural component comprises a material that is at least partially consumed when exposed to heat and a source of oxygen. The material may comprise a metal, such as magnesium, which is converted to magnesium oxide when exposed to heat and a source of oxygen. The downhole tool may further comprise a torch with a fuel load that produces the heat and source of oxygen when burned. The fuel load may comprise a flammable, non-explosive solid, such as thermite.

Abstract: The present invention relates to a fabric sail (1) which maintains a minimal surface. An elastic boundary is attached to the edges of an elastic membrane, and the edges (4) are shaped so that the membrane of the sail maintains a minimal surface configuration despite being deformed by the boundary. The sail therefore distributes strain across the sail surface and is thus free of wrinkles and creases. Points on the elastic membrane itself can be displaced but still form a minimal surface as defined by the boundary and the displaced surface connection points. In addition, strain matching allows the boundary and the elastic membrane to optimally share the strain caused by any deformation.

Abstract: A C-terminally modified Ubiquitin (Ub) derivative) ubiquitin vinyl sulfone (UbVS), which is specific for deubiquitinating enzymes (DUBs), was synthesized as an active site directed probe that irreversibly modifies a subset of Ub C-terminal hydrolases (UCHs) and Ub specific processing proteases (UBPs), is provided. [125I]-UbVS modifies 6 of the 17 known and putative yeast deubiquitinating enzymes, namely Yuh1p, Ubp1p, Ubp2p, Ubp6p, Ubp12p and Ubp15p. In mammalian cells, a greater number of polypeptides is labeled, most of which are DUBs. An additional DUB that associates with the mammalian 26S proteasome, novel protein USP14, a mammalian homolog of yeast Ubp6p that is bound to the proteasome, is provided.

Abstract: Egress processing of asynchronous transfer mode (ATM) cells is performed by an egress processor (18) that receives ATM cells from an ingress processor (16) through a cell bus (20). ATM cells are received in the egress processor (18) through an egress FIFO buffer (32) and placed within available space in an ECELL memory (38) through a single cell FIFO buffer (34) as controlled by a cell loader (36). A linker (44) chains together ATM cells, no matter where they are located in the ECELL memory (38), corresponding to a particular call into a specific packet by placing pointer information within each ATM cell of a specific packet such that each ATM cell points to the next ATM cell within the packet. The linker (44) places the cell location of the first cell of the packet into a packet FIFO buffer (52) of a cell location buffer (48).

Abstract: Call information is transmitted between broadband switching modules (12) and a broadband services switch (10). Each broadband switching module (12) receives call information from outside the broadband services switch (10) and translates the information into asynchronous transfer mode (ATM) cells. Each broadband switching module (12) also generates a route setup cell and a route teardown cell in order to establish and release a connection path to another broadband switching module (12), respectively. The broadband switching module (12) sends the route setup cell, that includes a virtual circuit identifier identifying the connection path for the calling information ATM cells, along a dedicated VCI to an intermediary broadband switching module (12). The sending broadband switching module (12) then transmits the payload ATM cells containing the calling information immediately after transmitting the route setup cell and before receiving an indication that a connection path has been established.
