Abstract: A method of electrospinning fibres is disclosed. The fibres have an inner core surrounded by a porous outer shell. The method comprises co-electrospinning first and second liquids as core and shell respectively, the second liquid surrounding the first liquid in a jet issuing from a Taylor cone, wherein the first and second liquids are miscible or semi-miscible with each other, such that pore generation is driven in the shell of the fibre. The liquids may be solutions or melts. The electrical conductivity, viscosity, miscibility and other parameters of the liquids determine the structure of the produced fibres. As well as producing fibres having a porous shell there are described methods of co-electrospraying porous beads as well as core-shell vesicles having a porous shell. The methods may be used to produce hydrogen storage fibres, vesicles and beads. The methods may also be used for producing controlled drug-delivery fibres, vesicles and beads.

Abstract: In an ordered semaphore management system a pending state allows threads not competing for a locked semaphore to bypass one or more threads waiting for the same locked semaphore. The number of pending levels determines the number of consecutive threads vying for the same locked semaphore which can be bypassed. When more than one level is provided the pending levels are prioritized in the queued order.

Abstract: Drug screening assays useful in the discovery of pharmaceutically active compounds for use in the treatment of diseases involving abnormal lipid metabolism including diabetic neuropathy are taught. In particular, the control region of delta-5-desaturase gene is taught as a target for the drug screening methods, which serve to identify nucleotides, proteins, compounds and/or other pharmacological agents, which modulate the activity of desaturase enzymes or regulate the level of expression of the desaturase genes. Cell-based and cell lysate assays are taught for detecting components that interact with the desaturase enzymes and modify fatty acid profiles. In addition, cell-based and cell lysate assays are used to identify functional and regulatory elements controlling expression of the desaturase genes as well as to screen for components that modulate the transcriptional activity of the desaturase genes. Also taught is the gene for rat delta-5-desaturase.

Abstract: A generic method and apparatus for managing semaphores in a multi-threaded processing system has a storage area for each of the threads in the processing system. Each storage area includes a first part for storing at least one indicia for identifying at least one unique semaphore from a plurality of semaphores utilized by the multi-threaded processing system and a second part for storing an indicia for indicating a locked status for the stored semaphore. A thread requiring a semaphore sends a semaphore lock request to the semaphore manager which examines the contents of all of the storage areas to determine the status of the requested semaphore. If the requested semaphore is not locked, it is locked for the requesting thread by inserting the requested semaphore and locked status in the memory location assigned to the requesting thread.

Abstract: Processor threads in a multi-processor system can concurrently lock multiple semaphores by providing a lock command which includes the semaphore value and a semaphore number. Each processor is allocated two or more addressable semaphore stores, each of which include a multi-bit field identifying the requested semaphore and a one bit field identifying the locked status of the requested semaphore. The semaphore number determines which of the allocated semaphore stores are to be used for processing the lock command.

Abstract: An ordered semaphore management subsystem and method for use in an application system which includes a plurality of processors competing for shared resources each of which is controlled by a unique semaphore. The subsystem generates an ordered semaphore field (OSF) corresponding to each processor in a linked list of processors and assigns one of four statuses to the OSF depending on the position the processor occupies in the linked list of processors competing for the shared resources. The four states are (1) semaphore head (SH); (2) behind semaphore head (BSH); (3) semaphore head behind (SHB); and (4) skip (Skip). Only the SH processor is allocated the semaphore when requested. A processor not in the SH state will be denied the semaphore even if is available to assure sequential access.

Abstract: A system and method of transmitting multiple output messages from a single input message system where the system is keeping the messages in order by correlating the output messages with the input messages. For each output message, an indicator is associated with the output message indicating whether this output message is the last message being generated for the given input message. This allows multicasting to occur in a system where the output is matched to the input by allowing multiple output messages to be associated with a single input message.
