摘要:
In embodiments of the present invention an undoped amorphous, nanocrystalline or microcrystalline semiconductor layer and a heavily doped amorphous, nanocrystalline, or microcrystalline semiconductor layer are formed on a monocrystalline silicon lamina. The lamina is the base region of a photovoltaic cell, while the amorphous, nanocrystalline or monocrystalline layers serve to passivate the surface of the lamina, reducing recombination at this surface. In embodiments, the heavily doped layer additionally serves as either the emitter of the cell or to provide electrical contact to the base layer. The undoped and heavily doped layers are deposited at low temperature, for example about 150 degrees C. or less with hydrogen dilution. This low temperature allows use of low-temperature materials and methods, while increased hydrogen dilution improves film quality and/or conductivity.

A near infrared phosphorescent organometallic complex includes a cyclometalating ligand and a transition metal. The cyclometalating ligand includes a fused aromatic ring structure with carbon atoms, and a heteronuclear aromatic ring with a nitrogen atom. The transition metal is bonded to the nitrogen atom in the heteronuclear aromatic ring and one of the carbon atoms in the fused aromatic ring structure. The heteronuclear ring can be part of the fused aromatic ring. The organometallic complex is capable of phosphorescent emission with maximum emission intensity occurring at a wavelength in a range from about 650 nm to about 2000 nm.

The present invention relates compositions and methods for microRNA (miRNA) expression profiling of colorectal cancer. In particular, the invention relates to a diagnostic kit of molecular markers for identifying one or more mammalian target cells exhibiting or having a predisposition to develop colorectal cancer, the kit comprising a plurality of nucleic acid molecules, each nucleic acid molecule encoding a miRNA sequence, wherein one or more of the plurality of nucleic acid molecules are differentially expressed in the target cells and in one or more control cells, and wherein the one or more differentially expressed nucleic acid molecules together represent a nucleic acid expression signature that is indicative for the presence of or the predisposition to develop colorectal cancer. The invention further relates to corresponding methods using such nucleic acid expression signatures for identifying one or more mammalian target cells exhibiting or having a predisposition to develop colorectal cancer as well as for preventing or treating such a condition. Finally, the invention is directed to a pharmaceutical composition for the prevention and/or treatment of colorectal cancer.
摘要:
A configuration system uses process plant items that may represent, or be capable of representing, entities in a process plant to assist in configuring, organizing, and changing the control and display activities within the process plant. Access to the items may be controlled by associating access control data with the items. The configuration system may also use objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant. Access to these objects may be controlled by associating access control data with the objects. The access control data may indicate whether users or certain users may be able to, for example, view or modify all or some data associated with the process plant items or the objects. The process plant items may comprise, for example, module class objects which may be capable of generically representing process entities of the process plant, module objects which may be capable of specifically representing process entities of the process plant, composite templates, module templates, etc. The objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant may comprise, for example, phase classes or unit phases.
