摘要:
Disclosed are methods for magnetic resonance imaging (MRI) that reduce the appearance of artifacts in a final image. Also provided are a computer readable medium comprising instructions that when executed by a CPU results in the reduction of artifacts in a magnetic resonance image, and an MRI apparatus comprising the computer readable medium. Also disclosed is a data processing method that provides further reduction of residual artifacts in a magnetic resonance image. The disclosed methods provide a simple and effective approach to ameliorate various artifacts in virtually any type of MRI scanners.

Pathway and landscape lights, in particular to devices, apparatus, systems and methods of using ground directed pathway and landscape lights with a single or perimeter spaced apart LED (light emitting diode) light sources on a disc mount, with or without an optical fiber arranged in a ring pattern about a perimeter edge of the mount. A light shade lens can have an upper end attached to the lower face of the disc mount, and a bottom end attached to a ground engaging post, so the light emitted from the mount is directed in a 360 degree outwardly expanding direction expanding outward on the ground surface where the ground engaging post is in the center of the 360 degree expanding illumination. A low voltage power source can be used. Alternatively, the light can be solar powered. The light forms uniform light beam emissions without shadow spots effects.

A fluid actuator with fluid limit valves (550, 551) and optional adjustable mechanical limits enables the construction of fluid linkages which are able to completely replace mechanical linkages. In a fluid circuit comprising of two or more fluid actuators, the pistons (102) of the fluid actuators can become uncorrelated when fluid leakage occurs. At the piston (102) extension and retraction limits, fluid limit valves (550, 551) open. The open fluid limit valves (550, 551) allow fluid to bypass pistons (102) and/or allow fluid from an external source to compensate the fluid leakage. The fluid bypassing pistons (102) at their extension or retraction limit and/or externally supplied fluid forces the uncorrelated pistons (102) to reach their extension or retraction limit as well. The fluid actuator with optional adjustable mechanical limits have one or more additional pistons (686, 688), which have an adjustable separation from the main piston (102) or end of cylinder. The fluid actuator with fluid limit valves (550, 551) and optional adjustable mechanical limits enables mechanical linkages to be replaced by fluid circuits composed of the fluid actuators.
摘要:
A system and method for constructing a schedule that better achieves one or more business goals by generating a schedule optimized for at least one business goal comprising either a business objective or a business constraint. The present system and method, in addition to using information about the set of tasks, any information about constraints about the tasks, the available resources, the time to complete the tasks, all costs and any additional information in relation to the available resources, the present method, also uses information about the costs associated with the project, the sales revenues or fees earned by the project, customer satisfaction and alternative resources, in order to generate an optimized schedule meeting one or more defined business goals.
摘要:
In a telecommunications system (100), a method and apparatus for buffering the initial speech of an initial speaker in a push-to-talk call is disclosed. The method includes the steps of determining at least one participant or group to call (410, 510), sending a call request to the at least one participant or group (520), determining if the at least one participant or group is registered with the telecommunications system, notifying the initial speaker to begin speaking after determining at least one participant is registered with the telecommunications system but prior to connecting all called parties, receiving and digitizing voice packets from the initial speaker, storing the digitized data packets in a storage medium and transmitting the digitized voice packets when a predetermined packet transmission triggering event occurs. The apparatus for buffering the initial speech burst of an initial speaker in a call includes a first server (140) and a second server (150) communicatively connected to the first server. The second server is programmed to execute the steps of the method described above.
摘要:
A method is provided for reducing the nitrogen oxide content of a flue gas produced by the combustion of fuel by introducing a nitrogen oxide removal agent into either the nitrogen oxide contaminated flue gas or the fuel to be combusted. The nitrogen oxide removal agent is the reaction product of a carbon compound in a pyrolysis liquor and a nitrogen compound such as ammonia, ammonium hydroxide or urea. The carbon compound is selected from carboxylic acids, phenols, esters, aldehydes and ketones. The pyrolysis liquor is derived from a feed stock containing cellulose, lignin or starch.

The disclosure provides a novel anti-angiogenesis fusion protein. The present invention combines a chimeric vascular endothelial cell growth factor (VEGF) receptor or a fragment thereof with a multimerizing component, which have a superior binding capacity with human VEGF and placental growth factor (PIGF). The fusion protein has improved stability, prolonged half-life and the ability to form multivalent interactions with VEGF, and can be used for anti-angiogenesis, treating VEGF related diseases and inhibiting tumor growth.

摘要:
The present invention relates in general to polypeptides having reduced susceptibility to oxidation, methods of selecting or making the polypeptides and methods of use thereof. The polypeptides having reduced susceptibility to oxidation are modified by amino acid substitution, deletion or insertion to confer reduced susceptibility to oxidation, thereby decreasing degradation of the polypeptide and extending the shelf-life and biological activity of the polypeptide under typical storage, handling and use conditions.
摘要:
A data processor timer comprising a writeable control register, a look-up table and a loadable counter. The loadable counter operates in a first mode to load the count data field and operates in a second mode an entry from said look-up table specified by the count data field. The loadable counter generating a time out signal upon counting a number of clock pulses equal to said count. The writeable control register preferably includes a mode bit selecting the first or second modes. This invention is suitable for a pre-scalar counter as part of a data processor watchdog timer.
