摘要:
The present invention provides methods and compositions for improving the efficiency of nucleic acid amplification reactions. The invention encompasses hybrid polymerases that show increased processivity over wild type polymerases as well as decreased exonuclease activity. The invention also encompasses methods, compositions and kits for conducting nucleic acid synthesis and amplification reactions in which non-specific amplification of primers is reduced.
摘要:
A network device is described that concurrently executing more than one instance of an operating system on a single processor. Each of the instances of the operating system executes completely independent of the other instances. In this way, disparate instances may exist for the same operating system or for different operating systems. The techniques allow the processor to concurrently execute, for example, an instance of the operating system may emulate a routing engine and an instance of the operating system may emulate an interface controller. A hyper scheduler performs context switches between the operating systems to enable the processor to concurrently execute the instances of the operating system. The techniques may provide a low cost alternative to employing multiple processors within a network device, such as a router, to execute multiple independent operating systems.

A geospatial modeling system may include a geospatial model data storage device containing geospatial model data including a plurality of groups of tree crown vegetation points and a display. The system may further include a processor cooperating with the geospatial model data storage device and the display for displaying a simulated tree trunk beneath a group of tree crown vegetation points, and displaying at least one level of simulated tree branches for the simulated tree trunk. Each tree branch may be positioned based upon determining a branch distal reference point beneath a cluster of tree crown vegetation points from among the group of tree crown vegetation points.

Methods and systems of maintaining, evaluating, and providing therapy to a lung ex vivo. The methods and systems involve positioning the lung in an ex vivo perfusion circuit; circulating a perfusion fluid through the lung, the fluid entering the lung through a pulmonary artery interface and leaving the lung through a left atrial interface; and ventilating the lung by flowing a ventilation gas through a tracheal interface. Maintaining the lung for extended periods involves causing the lung to rebreath a captive volume of air, and reaching an equilibrium state between the perfusion fluid and the ventilation gas. Evaluating the gas exchange capability of the lung involves deoxygenating the perfusion fluid and measuring a time taken to reoxygenate the perfusion fluid by ventilating the lung with an oxygenation gas.

A light diffusion device for uniformly dispersing light across a gauge dial plate having indicia associated therewith includes an annular member of transparent or translucent material having front and rear annular surfaces each merging with an outer peripheral surface and an inner peripheral surface. The inner peripheral surface is a frusto-conical widening in a direction from the rear surface toward the front surface to reflect light rays toward the outer peripheral and front surfaces thereby effecting uniform illumination across the front surface, and the outer peripheral surface and frusto-conical inner peripheral surface share a coincident axis of generation.

A method and apparatus for intelligent scrolling. In a computer system that has a user interface which allows for the movement of items from a first open window to a second open window or to a second region, such as a desktop, the present invention allows a user to select one or more items in the first window, move the selected item(s) to within a predetermined distance from an edge of the first window for a predetermined period of time and cause the viewable portion of the data and/or document within the first window to scroll in a corresponding direction.
摘要:
A mounting assembly for an object is provided, including a first mounting element, a second mounting element, and a resilient spring located therebetween. An object can be secured to either one of the first mounting element and the second mounting elements. In addition or alternatively, a method of manufacturing the mounting assembly is also provided. The method includes the steps of molding a resilient spring directly to the first mounting element, attaching the second mounting element to the spring, and attaching an object to either of the first and second mounting elements. In addition or alternatively, another method of manufacturing is provided for manufacturing a plurality of mounting assemblies. In addition or alternatively, the first mounting element can include a base member and a leg member. In one example, the leg member can be movable relative to the base member.

A flow-through muffler includes a plurality of heat conducting walls, baffles, or partitions that together define a plurality of passages arranged to form acoustic waveguides, attenuators, and/or cancellation chambers, the walls, baffles, or partitions increasing a surface area exposed to the exhaust gases to facilitate extraction of heat while attenuating or canceling the resulting sound pressure waves. The muffler may have a cooling arrangement mounted thereon, and thermoelectric generator elements or other heat-powered device, such as a reformer, connected across the heat differential between the cooling arrangement and an exterior surface of the muffler housing that is in thermal contact with the heat conducting walls, bafflers, or partitions. In addition, the muffler may be made tuneable by providing a device for varying a length of one of the passages relative to another passage, and by including a sound cancellation chamber at an intersection of the passages. In addition, the internal surfaces of the muffler may be coated with a catalyst to provide a combination muffler and catalytic converter.
