A catalyst which comprises nickel and/or cobalt supported on a support that includes a mixed oxide containing metals, such as aluminum, zirconium, lanthanum, magnesium, cerium, calcium, and yttrium. Such catalysts are useful for converting carbon dioxide to carbon monoxide, and for converting methane to hydrogen.

Methods of identifying microRNA labeled with a fluorescent probe in a biological sample are disclosed. The methods include obtaining a plurality of fluorescence images of the sample and forming an image stack based on the plurality of fluorescence images, decomposing the image stack to obtain a component image that corresponds to the labeled microRNA, and identifying the microRNA based on the component image.

An exemplary vibrating mass gyroscope uses a mass disposed for movement along an x-axis and y-axis. First and second electrodes are disposed adjacent surfaces of the mass along an x-axis and y-axis. Circuitry, coupled to the first and second electrodes, provides during a first mode a dither driving voltage on one of the first and second electrodes causing vibrating displacement of the mass along the one of the x-axis and y-axis. The measurement voltage is sensed on the other of the first and second electrodes where the measurement voltage represents a first angular rate value. During a second mode, the circuitry provides a dither driving voltage on the other of the first and second electrodes causing vibrating displacement of the mass along the other of the x-axis and y-axis and measurement voltage is sensed on the one of the first and second electrodes where the measurement voltage represents a second angular rate value. A combiner coupled to the circuitry receives the first and second angular rate values, and generates a resulting angular rate value based on both the first and second angular rate values wherein common bias errors are canceled. The common bias errors cancel because the pickoff sensing axis is coincident with the forcing axis when the same electrode is used for both the forcing and for the pickoff.
摘要:
Aspects of the present invention encompass the collection of multispectral images from a population of objects, and the analysis of the collected images to measure at least characteristic of the population, using photometric and/or morphometric features identifiable in the collection of images. In an exemplary application, the objects are biological cells. In a particularly preferred, but not limiting implementation, the plurality of images for each individual object are collected simultaneously. In an empirical study the characteristic being measured involves the synapse between conjugated cells. The conjugated cells may represent a subpopulation of the overall population of objects that were imaged. In a particularly preferred, yet not limiting embodiment, the present invention enables the quantization of the redistribution of cellular molecules due to the conjugation of different biological cells. Significantly, such quantization is not feasible with standard microscopy and flow cytometry.

Compositions, kits and methods for reducing or inhibiting apoptosis in a cell or tissue and for treating or preventing an apoptosis-related disease or condition in a mammal that is not infected with HIV are disclosed. The methods involve administering to said mammal a therapeutically effective amount of one or more HIV protease inhibitors, and/or reducing mitochondrial adenine nucleotide translocator (ANT) dependent permeability transition pore complex (PTPC) opening and/or mitochondrial cytochrome c release in target cells or tissues.
摘要:
A cap (10) is provided for the load box (16) of a vehicle, like a pickup truck (12), including a box-like structure sized and adapted to fit on the load box to form an enclosed area for the storage of personal items, camping equipment, tools, parts or the like. On the forwardmost corner of the cap there is included a door (40) in the form of three-sided box (53, 58, 60), i.e., a door that wraps both around the forward corner of the cap and into the roof. Hinges (50) are provided at the cutline with the roof so that the door opens upwardly. In the preferred embodiment, closable and latchable steps (28) are structurally integrated into the a side of a load box at its forwardmost end and the door of the cap is aligned with the steps forming a doorway for improved ingress and egress to the enclosed area under the cap.

An initiator assembly (38) is factory-pre-assembled and comprises an initiation fixture (10) secured to a triggering device (40). The initiation fixture (10) comprises a unitary body, i.e., one without moving parts, and includes a bushing groove (18) to receive as an accessory an O-ring (64) to seal the device within the barrel (42) of the triggering device (40). A fuse/fixture sub-assembly (34) includes an initiation charge (30) disposed at the firing face (13a) and a signal-transmission fuse (22). The initiation fixture (110) may be a “universal” fixture having thereon optional external threads (36) and being otherwise dimensioned and configured to be received within either an internally threaded barrel (42) of a triggering device (40) or the barrel (42) of a triggering device which utilizes a fuse-holder cap (56). The initiator assembly (38) may include a spool (66) on which the signal-transmission tube (22) is wound.
