A pixel-based display utilizes persistence-of-vision to sweep text and graphics in a cylindrical plane, including time and date, custom messages and animations. The display is generated from a light array with a column of modulated light emitting elements, which is mounted on a rotating display assembly. Power and data are combined on a fixed control assembly and inductively coupled to the display assembly. A control assembly processor interprets a display application language that describes display-specific tasks to generate command, mode, character and graphic data for the display assembly. The control assembly processor also reads a trigger position sensor and adds a trigger delay to generate a virtual trigger command, which provides for flexible display positioning and scrolling display effects.

The present invention relates to an arylphenoxy catalyst system producing an ethylene homopolymer or copolymers of ethylene and α-olefins, and a method of producing an ethylene homopolymer or copolymers of ethylene and α-olefins having a high molecular weight under a high temperature solution polymerization condition using the same. The catalyst system includes a group IV arylphenoxy-based transition metal catalyst and an aluminoxane cocatalyst or a boron compound cocatalyst. In the transition metal catalyst, a cyclopentadiene derivative and arylphenoxide as fixed ligands are located around the group IV transition metal, arylphenoxide is substituted with at least one aryl derivative and is located at the ortho position thereof, and the ligands are not crosslinked to each other. The catalyst includes an environmentally-friendly raw material, synthesis of the catalyst is economical, and thermal stability of the catalyst is excellent. It is useful for producing an ethylene homopolymer or copolymers of ethylene and α-olefins having various physical properties in commercial polymerization processes.

The invention is directed to mixtures of polysilanes macroscopically solid at ambient temperature wherein the individual components of the composition Si_nH_2n and/or Si_nH_2n+2 of which decompose before they are boiling at an applied process pressure and which are produced from the hydrogenation of plasmachemically generated largely chlorinated polysilane mixtures. These mixtures of polysilanes are especially suited to be applied onto surfaces as solutions or dispersions and to obtain silicon-based structures or layers in subsequent process steps. Furthermore, they are especially safe in handling and can be additionally made up into transport forms in suitable transport containers.

Small molecule, peptidic hepatocyte growth factors mimics, which act as both mimetics and antagonists, have been generated. These molecules have been shown or predicted to have therapeutic potential for numerous pathologies including dementia (e.g. Alzheimer's) and Parkinson's disease.

A vaccine is described which provides protection against a broad spectrum of viral strains, including but not limited to influenza A strains such as H1N1, H3N2, and H5N1. Embodiments of the present invention offer a number of advantages over conventional vaccine, in that they are cheaper to synthesize, more stable, easily scalable, and amenable to further genetic manipulation. Most importantly, certain embodiments of the present invention contemplate features, including but not limited to endosomal targeting, which result in a more robust immune response.

A process performs solid phase synthesis of halogenated derivatives of fluorescein, and includes reacting fluorescein with a halide MX, wherein M is an alkali metal and X is a halogen, and Oxone(R) ( 2 KHSO₅.KHSO₄.K₂SO₄), at a temperature higher than or equal to 150° C. A structure uses a halogenated derivative of fluorescein selected from the group consisting of 2',4',5'-trichlorofluorescein, 2',4',5',7'-tetrachlorofluorescein, 4',5'-diiodofluorescein diacetate and 2',4',5'-triiodofluorescein as electro-bistable material in a non-volatile memory device.

The invention relates to a silicone composition comprising components bearing ≡SiH/≡SiOH groups, which can be polymerized/cross-linked by means of a dehydrogenative condensation reaction in the presence of a carbene-type catalyst in solution.
