摘要:
An ultrasonic field-portable system for accurately measuring hematocrit (HCT) and hemoglobin concentration (HGB) in small food samples. The system includes an analyzer (10) that allows extremely accurate measurements of blood hematocrit from only one or two drops of +>>d collected in a disposable sampling device (12) that is then inserted into the analyzer (10). The system is compact enough to package into a point of care device, making it a point of care device with accuracy comparable to larger CBC lab equipment.

A system for determining the relative displacement of a rigid object is described herein. In one embodiment, the system includes three data sources positioned on an object. The data sources are configured to transmit data relating to positional displacement of the object. Each data source has predefined movement parameters based on the position of each data source on the object. In one embodiment, the system further includes a receiver unit configured to display positional information relating to the object based on the data received from each data source. The positional information represents a single valid solution set generated in part by eliminating positional movements that exceed the predefined movement parameters.

A semiconductor substrate useful as a donor wafer is a single-crystal silicon wafer having a relaxed, single-crystal layer containing silicon and germanium on its surface, the germanium content at the surface of the layer being in the range from 10% by weight to 100% by weight, and a layer of periodically arranged cavities below the surface. The invention also relates to a process for producing this semiconductor substrate and to an sSOI wafer produced from this semiconductor substrate.

Chimeric human-bovine parainfluenza viruses (PIVs) are infectious and attenuated in humans and other mammals and useful individually or in combination in vaccine formulations for eliciting an anti-PIV immune response. Also provided are isolated polynucleotide molecules and vectors incorporating a chimeric PIV genome or antigenome which includes a partial or complete human or bovine PIV “background” genome or antigenome combined or integrated with one or more heterologous gene(s) or genome segment(s) of a different PIV. Chimeric human-bovine PIV of the invention include a partial or complete “background” PIV genome or antigenome derived from or patterned after a human or bovine PIV virus combined with one or more heterologous gene(s) or genome segment(s) of a different PIV virus to form the human-bovine chimeric PIV genome or antigenome. In certain aspects of the invention, chimeric PIV incorporate a partial or complete human PIV background genome or antigenome combined with one or more heterologous gene(s) or genome segment(s) from a bovine PIV, whereby the resultant chimeric virus is attenuated by virtue of host-range restriction. In alternate embodiments, human-bovine chimeric PIV incorporate a partial or complete bovine PIV background genome or antigenome combined with one or more heterologous gene(s) or genome segment(s) from a human PIV gene that encode a human PIV immunogenic protein, protein domain or epitope, for example encoded by PIV HN and/or F glycoprotein gene(s) or genome segment(s). Human-bovine chimeric PIV of the invention are also useful as vectors for developing vaccines against other pathogens. A variety of additional mutations and nucleotide modifications are provided within the human-bovine chimeric PIV of the invention to yield desired phenotypic and structural effects.

In a non-volatile memory, the displacement current generated in non-selected word lines that results when the voltage levels on an array's bit lines are changed can result in disturbs. Techniques for reducing these currents are presented. In a first aspect, the number of cells being simultaneously programmed on a word line is reduced. In a non-volatile memory where an array of memory cells is composed of a number of units, and the units are combined into planes that share common word lines, the simultaneous programming of units within the same plane is avoided. Multiple units may be programmed in parallel, but these are arranged to be in separate planes. This is done by selecting the number of units to be programmed in parallel and their order such that all the units programmed together are from distinct planes, by comparing the units to be programmed to see if any are from the same plane, or a combination of these. In a second, complementary aspect, the rate at which the voltage levels on the bit lines are changed is adjustable. By monitoring the frequency of disturbs, or based upon the device's application, the rate at which the bit line drivers change the bit line voltage can be adjusted. This can be implemented by setting the rate externally, or by the controller based upon device performance and the amount of data error being generated.

摘要:
Attenuated, recombinant negative stranded RNA viruses suitable for vaccine use are produced from one or more isolated polynucleotide molecules encoding the virus. A recombinant genome or antigenome of the subject virus is modified to encode a mutation within a recombinant protein of the virus at one or more amino acid positions(s) corresponding to a site of an attenuating mutation in a heretologous, mutant negative stranded RNA virus. A similar attenuating mutation as identified in the heterologous negative stranded RNA virus is thus incorporated at a corresponding site within the recombinant virus to confer an attenuated phenotype on the recombinant virus. The attenuating mutation incorporated in the recombinant virus may be identical or conservative in relation to the attenuating mutation identified in the heterologous, mutant virus. By the transfer of mutations into recombinant negative stranded RNA viruses in this matter, candidate vaccine viruses are engineered to elicit a desired immune response against a subject virus in a host susceptible to infection thereby.

Thread synchronization methods and apparatus for managed run-time environments are disclosed. An example method disclosed herein comprises determining a set of locking operations to perform on a lock corresponding to an object, performing an initial locking operation comprising at least one of a balanced synchronization of the lock and an optimistically balanced synchronization of the lock if the initial locking operation is not unbalanced, and, if the initial locking operation is active and comprises the optimistically balanced synchronization, further comprising modifying a state of a pending optimistically balanced release corresponding to the optimistically balanced synchronization if a subsequent locking operation is unbalanced.
