Abstract: A method, an apparatus, and a computer program product in a data processing system are presented for using hardware assistance for gathering performance information that significantly reduces the overhead in gathering such information. Performance indicators are associated with instructions or memory locations, and processing of the performance indicators enables counting of events associated with execution of those instructions or events associated with accesses to those memory locations. The performance information that has been dynamically gathered from the assisting hardware is available to the software application during runtime in order to autonomically affect the behavior of the software application, particularly to enhance its performance. For example, the counted events may be used to autonomically control an execution-path selection within the software application.

Abstract: A method, apparatus, and computer instructions in a data processing system for processing instructions and monitoring accesses to memory location ranges. An instruction for execution is identified. A determination is made as to whether the instruction is within a contiguous range of instructions. Execution information relating to the instruction is identified if the instruction is within the contiguous range of instructions. With memory location accesses, an access to a memory location is identified. A determination of whether the memory location is within a contiguous range of memory locations is made. Access information is identified if the memory location is within the contiguous range of memory locations.

Abstract: A method, apparatus, and computer instructions in a data processing system for processing instructions. Instructions are received at a processor in the data processing system. If an indicator is associated with the instruction, the execution of the instruction and all subsequent instructions are counted until another indicator is received. The indicator also is used with data locations to count accesses to data in the data locations. If the indicator is associated with a data location, all subsequent data location accesses are counted until another indicator is received.

Abstract: A method, apparatus, and computer instructions in a data processing system for processing instructions. Instructions are received at a processor in the data processing system. If a selected indicator is associated with the instruction, counting of each event associated with the execution of the instruction is enabled.

Abstract: A method, apparatus, and computer instructions in a data processing system for processing instructions. An instruction is received at a processor in the data processing system. If an indicator is associated with the instruction in which the indicator identifies a threshold value, execution of the instruction is counted if a time for executing the instruction exceeds the threshold value. Responsive to a request to access data, a determination is made as to whether the indicator is associated with the data. The indicator identifies a threshold value. Access to the data is counted if the indicator is associated with the data and if a time needed to access the data exceeds the threshold value.

Abstract: A method, apparatus, and computer instructions in a data processing system for monitoring the execution of instructions and accesses to memory locations. If an instruction is associated with a indicator, a counter associated with the instruction is incremented in response to detecting execution of the instruction. The indicator may be associated with a memory location with a counter associated with the memory location being incremented in response to an access of the memory location.

Abstract: A method, apparatus, and computer instructions in a data processing system for monitoring processing of instructions and memory locations. An instruction is received in the data processing system for execution. If an enabled state is present, a determination is made whether the instruction is associated with an indicator in a shadow memory. A selected action is performed in response to the indicator being associated with the instruction. Responsive to being in an enabled state when a data access to a memory location occurs, a determination is made as to whether the memory location is associated with an indicator in a shadow memory. A selected action is performed in response to the indicator being associated with the memory location.

Abstract: A method, apparatus, and computer instructions in a data processing system for processing instructions. An instruction is identified for execution within a processor in the data processing system. If an indicator is associated with the instruction then an interrupt is forced. With data accesses, a determination is made as to whether the indicator is associated with the data in response to an access of data. An interrupt is generated if the data is associated with the indicator.

Abstract: Hepatitis C virus (HCV) is a major cause of chronic liver disease and affects over 270 million individuals worldwide. The HCV genome is a single-stranded RNA that functions as both a messenger RNA and replication template, making it an attractive target for the study of RNA interference. Double-stranded short interfering RNA (siRNA) molecules designed to target the HCV genome are disclosed herein.

Abstract: A tag comprising a plastic container having at least one particle therein. The or each particle may be formed from metal or metal coated and/or fabricated from a plurality of different metals. A receiver unit adapted to detect RF pulses arising as a result of the Triboelectric effect of the particles enables detection of a tag.

Abstract: A method, a system, an apparatus, and a computer program product are presented for loading LDIF ( (Lightweight Directory Access Protocol (LDAP) Data Interchange Format) data into a directory. A single reader thread reads entries from an LDIF file; each entry is associated with a priority value, e.g., the priority value for an entry may be based on the number of delimiters in the distinguished name within the entry. Multiple loading threads concurrently add the entries into an LDAP directory in accordance with their associated priority values. The entries are added to the LDAP directory in an order of highest indicated priority to lowest indicated priority; entries that are associated with priority values that indicate equal priority are considered to be equivalent for the purposes of ordering the entries, so entries that have equal priority may be added to the LDAP directory in any order.

Abstract: A hollow building element (10) of plastics material comprises one of more longitudinal ducts (30) and has, at opposite sides thereof, coupling members (32,34), whereby elements are connected together directly or indirectly, wherein an upper coupling member at one side of an element is a hook like member and an upper coupling member at the opposite side of the element include a latch for the hook-like member of another like element. Building structures are created by connecting together such building elements.

Abstract: The invention provides anti-pathogen polypeptide and polynucleotide compositions, and methods of use. In general, the composition of the invention provide a modified pro-polypeptide comprising a pro-domain, a pathogen protease cleavage site, and a cytotoxic domain which can be activated by cleavage of the pro-polypeptide by a protease of an intracellular pathogen. The invention further provides nucleic acids encoding the subject polypeptides, and vectors and host cells comprising the subject nucleic acids. Cleavage of the pro-polypeptide by the pathogen protease results in activation of the cytotoxic domain, and decreases the viability of the pathogen-infected host cell. Methods for using the subject nucleic acids and polypeptides to reduce the viability of a pathogen-infected cell, and for reducing the pathogen load of a subject infected with a pathogen are provided. The invention further provides kits for carrying out the subject methods.

Abstract: All-optical timing extraction and optical clock recovery for high-speed return-to-zero binary optical data streams using the timing difference between clock and data counter-propagating optical pulses in a non-linear optical waveguide where the first pulse to arrive at the non-linear optical waveguide partially saturates the transmission properties of the waveguide resulting in a change of the transmission properties seen by the lagging pulse. A balanced photo-detector makes delay-dependent comparisons of the clock and data pulses' peak power and generates an error signal used in a phase-locked loop configuration to synchronize the clock to the data stream.
