Abstract:
This invention is directed to methods for forming an olefin stream from a methanol stream. A lower grade methanol, such as chemical grade or crude methanol, can be used as feed to form the olefin stream. The process uses a relatively simple distillation type step to vaporize a portion of the methanol feed stream and send the resulting vapor stream to a reaction unit to form the olefin stream. In addition, the invention provides the ability to operate the downstream recovery units with reduced fouling or plugging due to the presence of fine solids components.
Abstract:
Compounds having the formula (1) pharmaceutical compositions containing them and their methods of use for the treatment of neurological disorders related to amyloid B protein production and neurological disorders such as Alzheimer's disease. These compounds inhibit γ secretase and thereby inhibit the production of amyloid β protein, thereby acting to prevent the formation of neurological deposits of amyloid protein.
Abstract:
A multi-media device interface (18) couples a multi-media device (16) to a portable electronic device (10). Multi-media and other information can be loaded into the portable electronic device (10) from the multi-media device (16) or stored in the multi-media device (16) from the portable electronic device (10). The multi-media device interface (18) queues commands to the multi-media device (16) from the portable electronic device (10) while the multi-media device (16) completes a previously-issued command.
Abstract:
Color selection may be provided. First, a selection of a target object may be received and a color selection mode may be entered. Then a color preview may be provided in response to entering the color selection mode. Next, a color selection may be received in response to providing the color preview. A color of a property of the selected target object may then be set to the received color selection.

Abstract:
A method (500) and a mobile station (160) for reporting multi-path signals based on a report window are described herein. The mobile station (160) may determine a distribution of a plurality of multi-path signals observed by a receiving unit (220) within the mobile station (160). The mobile station (160) may determine a report window based on the distribution. Based on the report window, the mobile station (160) may report at least one of the plurality of multi-path signals.
Abstract:
Relative quantitative information about components of chemical or biological samples can be obtained from mass spectra by normalizing the spectra to yield peak intensity values that accurately reflect concentrations of the responsible species. A normalization factor is computed from peak intensities of those inherent components whose concentration remains constant across a series of samples. Relative concentrations of a component occurring in different samples can be estimated from the normalized peak intensities. Unlike conventional methods, internal standards or additional reagents are not required. The methods are particularly useful for differential phenotyping in proteomics and metabolomics research, in which molecules varying in concentration across samples are identified. These identified species may serve as biological markers for disease or response to therapy.
