The method includes storing a record in a memory associated with a system manager that assigns the storage retention criteria to the certain electronic data, designating the storage media available for overwrite after the threshold set in the storage retention policy has been exceeded, identifying the certain storage media available for overwrite, and retrieving information from the certain media after the threshold set in the storage retention policy has been exceeded.
Abstract:
The invention provides methods, compositions, and systems for a reversible hydrogen storage material. The hydrogen storage material contains a lithium-magnesium compound, having LiMgN in a dehydrogenated state and a hydrogenated lithium magnesium product in a hydrogenated state, where the hydrogenated and dehydrogenated states are reversible. The lithium-magnesium compound is formed by reacting MgH2 and LiNH2 in a substantially inert atmosphere in amounts sufficient to obtain a hydrogen adsorption of at least 3 wt %, and in many cases up to about 8.1 wt %.

Abstract:
Novel glycopeptide antibiotic derivatives. These derivatives are represented by the formula (aglycon part of glycopeptide antibiotic derivative)-(Sac-NH)—RA [wherein (aglycon part of glycopeptide antibiotic derivative) is the part formed by removing the sugar part from a known glycopeptide antibiotic derivative; (Sac-NH) part is an amino sugar part or a sugar chain part containing an amino sugar; and RA represents, e.g., the formula —X1—Ar1—X2—Y—X3—Ar2 (wherein X1, X2, and X3 each represents 1) a single bond or 2) a heteroatom or heteroatom-containing group selected from the group consisting of —N═, ═N—, —NR1—, —O—, etc.; Y represents —NR2CO— or —CONR2— (wherein R2 represents hydrogen or lower alkyl), etc.)]. These derivatives have antibacterial activity against vancomycin-resistant bacteria.

Abstract:
A system, method and program product for enhancing dose uniformity during ion implantation are disclosed. The present invention is directed to allowing the use of an at least partially untuned ion beam to obtain a uniform implant by scanning the beam in multiple rotationally-fixed orientations (scan directions) of the target at variable or non-uniform scan velocities. The non-uniform scan velocities are dictated by a scan velocity profile that is generated based on the ion beam profile and/or the scan direction. The beam can be of any size, shape or tuning. A platen holding a wafer is rotated to a new desired rotationally-fixed orientation after a scan, and a subsequent scan occurs at the same scan velocity profile or a different scan velocity profile. Also included is a method, system and program product for conducting a uniform dose ion implantation in which the target is rotated and tilted about greater than one axes relative to the ion beam.
Abstract:
An apparatus comprising an input circuit, a storage circuit and an output circuit. The input circuit may be configured to generate a plurality of data paths in response to an input data signal having a plurality of data items sequentially presented in a first order. The storage circuit may be configured to store each of the data paths in a respective shift register chain. The output circuit may be configured to generate an output data signal in response to each of the shift register chains. The output data signal presents the data items in a second order different from said first order.
Abstract:
A staged method of forming vinyl (e.g. acrylate) copolymer by solution polymerization which involves a) charging up to 90% of at least two vinyl monomers of the vinyl copolymer to a first stage reaction zone, b) polymerizing the at least two vinyl monomers to about 10 to 90% conversion in the presence of an initiator at an initiator to monomers mole ratio within a specified range, the monomer content of one of the at least two vinyl monomers of the copolymer formed in the first stage being higher than the content of another of the at least two vinyl monomers in the first stage polymer, the weight average molecular weight of the first stage copolymer being about 2000 to 500,000 Daltons; and c) continuing polymerization in the presence of an initiator in a second stage while continuously adding the balance of the monomers of said vinyl copolymer to the polymerization reaction mixture of the first stage at a monomers ratio lower in the one monomer than in the first stage monomers ratio, the initiator to monomers mole ratio in the second stage being different than in the first stage; the vinyl copolymer formed gradually continuously changing in molecular weight from the first stage and increasing in concentration of the one monomer during the second stage, the weight average molecular weight of the total copolymer of both stages being about 2,000 to 250,000 Daltons.
Abstract:
A variable aperture assembly (30) is provided for controlling the amount of ion beam current passing therethrough in an ion implantation system (10). The aperture assembly (30) comprises an aperture (44) defined by opposing first and second aperture plates (44A, 44B) through which an ion beam passes; control arms (46A, 46B) connected, respectively, to the first and second aperture plates (44A, 44B); and an aperture drive mechanism (36) for simultaneously imparting movement to the control arms in opposite directions, to adjust a gap (50) between the aperture plates (44A, 44B) to thereby control the amount of current passing through the aperture (44). Each of the opposite directions in which the control arms move is generally perpendicular to an axis along which the ion beam passes. A control system (120) is also provided for automatically adjusting the aperture gap (50) based on inputs representing actual ion beam current passing through the implanter, desired ion beam current, and aperture position. The control system (120) includes control logic (122, 124) for receiving the inputs and outputting control signals (126, 128) to the aperture drive mechanism to adjust the aperture gap.
