Abstract: Nucleic acid construct systems are disclosed. The constructs comprise: (i) a first nucleic acid construct comprising a first nucleic acid sequence encoding a first reporter polypeptide linked to an additional nucleic acid sequence capable of inserting the first nucleic acid construct into a genome of a host cell such that an endogenous polypeptide covalently attached to the first reporter polypeptide is expressed in the cell; and (ii) a second nucleic acid construct comprising a second nucleic acid sequence encoding a second reporter polypeptide, linked to an additional nucleic acid sequence capable of inserting in a non-directed manner the second nucleic acid construct into a genome of a host cell such that an endogenous polypeptide covalently attached to the second reporter polypeptide is expressed in the cell, wherein the first reporter polypeptide and the second reporter polypeptide are distinguishable.

Abstract: A method for analyzing the temporal behavior of gene expression for a group of genes which are part of a biological system or subsystem. Preferably, such an analysis enables the order of expression of such genes to be determined. More preferably, the temporal behavior of gene expression is assessed according to the analysis of the kinetics of gene transcription. According to a preferred embodiment of the present invention, the kinetics of gene transcription are measured according to promoter activity of a plurality of genes. More preferably, such kinetics are measured in a living organism or a portion of such an organism, such as a cell for example. For single-celled organisms, such as bacteria for example, the kinetics may easily be measured for the entirety of the living organism.

Abstract: A positive-pressure respirator hood assembly comprising, a gas-impermeable hood made of a flexible material, formed with at least a transparent visor portion; a gas treatment unit, comprising a filter and a power-operated blower to force air through the filter and generate a positive pressure within the hood; a one-way purge valve for facilitating the exhaust of exhaled gases and moisture from the hood; and a sealing portion for sealingly securing the hood over a body portion of the user; the respirator hood assembly is designed to be compactly received in a container and to be deployed into an operative state automatically, whereby a user is provided protection from toxic gases and particulate material.

Abstract: A method for analyzing data, such as biological data for example, for identifying one or more network motifs, or recurring patterns of relationships and/or behavioral connections between the components of a complex system. The method of the present invention is optionally and preferably applied to biological systems, such as gene regulatory systems for example.

Abstract: Systems and methods for enhanced quantitative analysis of hybridization intensity measurements obtained from oligonucleotide probes and other probes exposed to target samples are provided by virtue of the present invention. One embodiment ameliorates the effects of high frequency noise superimposed on a hybridization intensity measurement signal measured over successive probe alignments to a target sample sequence. Detection of expressed genes and ESTs and quantitative measurement of expression level may be improved. Mutation detection and base calling may be improved.

Abstract: The present invention concerns a method for accessing a computerized network suck as the Internet, wherein the user can choose whether to browse the Internet under his actual user name or under a user alias.

Abstract: An insecticidal device is provided which has a panel of a color having insect attracting properties, preferably yellow, and a spherical body of another color, preferably red. The spherical body is capable of defusing a liquid which contains an insect attractant and is combined with the panel in a manner that they form together an essentially flat panel having hemispherical bulges formed by the spherical body. A specific panel, which can be used as a panel in the above device and can be used as an independent insecticidal device is also provided.
