摘要:
An improved field effect transistor formed in the Group III nitride material system includes a two part structure in which a chemical vapor deposited passivation layer of silicon nitride encapsulates a previously sputtered-deposited layer of silicon nitride. The sputtered layer provides some of the benefits of passivation and the chemical vapor deposited layer provides an excellent environmental barrier.

Methods are disclosed for generating and isolating an informative content repository of respiratory related biomarkers to accurately determine whether an individual has normal or abnormal pulmonary function. Specifically, methods are directed to determination of whether individuals have chronic obstructive pulmonary disease, and if so, whether the affected individuals experience rapid long decline or slow lung decline as a result of COPD. Also disclosed is an informative content repository of chronic obstructive pulmonary disease biomarkers, which when linked with other informative content provides a powerful tool for diagnosis, study, therapeutic discovery and development, condition management, health maintenance, and linking chronic obstructive pulmonary disease through pattern of life style, environmental exposure, and genetic susceptibility and inheritance. Disclosed herein is a chronic obstructive pulmonary disease biomarker informative content repository comprising at least one COPD biomarker, apparatus and methods to diagnose, assess, address, and ameliorate related conditions.
摘要:
High reliable energy density capability of double-layer capacitor electrode technology now enables the use of capacitors as supplements to, or replacements for, battery technologies. In one application, when sized to a standard battery form factor, the large end terminal surface areas of such form factors enable that the energy density of capacitors can now be safely used as direct drop-in replacements for batteries.

A lounge chair assembly having a seat portion, pivotally associated back portion, and further pivotally associated lower leg portion. Each of the seat, back and leg portions includes an outer frame to which is secured an inner user supporting covering. Pairs of spaced apart and downwardly extending legs, either four or six in total, extend from locations associated with the intermediate seat portion. Each of the legs includes an outer fixed portion and a telescopically extending inner portion adjustable to vary a height of the seat portion relative to a supporting ground surface. Recess mounted and outwardly displaceable handle portions are associated with first and second side frame locations of the seat portion to facilitate transport of the same. Also, a side frame mounted and pivotable canister assembly releasably secures a selected item.
摘要:
A method of predicting whether a peptide present in a biological sample will be detected by analysis with a mass spectrometer. The method uses at least one mass spectrometer to perform repeated analysis of a sample containing peptides from proteins with known amino acids. The method then generates a data set of peptides identified as contained within the sample by the repeated analysis. The method then calculates the probability that a specific peptide in the data set was detected in the repeated analysis. The method then creates a plurality of vectors, where each vector has a plurality of dimensions, and each dimension represents a property of one or more of the amino acids present in each peptide and adjacent peptides in the data set. Using these vectors, the method then generates an algorithm from the plurality of vectors and the calculated probabilities that specific peptides in the data set were detected in the repeated analysis. The algorithm is thus capable of calculating the probability that a hypothetical peptide represented as a vector will be detected by a mass spectrometry based proteomic platform, given that the peptide is present in a sample introduced into a mass spectrometer.

An assembly for creating a portable enclosure includes a plurality of individual and elongated ground engaging units, each having an elongated body and an end extending ground engaging portion. A magazine fixedly secures in vertically extending fashion along each of the units, a screen adapted to being withdrawn from the magazine and including hooks defined along a forward withdrawable edge. A plurality of rings extend along a further vertically extending edge associated with each of the units, and which is adapted to receive the hooks associated with a screen withdrawn from a succeeding located unit, in order to construct a barrier between the units.

Electrospray ionization (ESI) apparatuses and methods of making the same are disclosed. In one embodiment, an ESI emitter comprises a capillary tube filled with a porous monolithic material, wherein the end of the emitter is tapered and the tip of the tapered end comprises a protrusion of the porous monolithic material. One embodiment of the method for making ESI emitters comprises filling a capillary tube with a porous monolithic material and tapering the end of the capillary tube, thereby exposing a portion of the porous material. The exposed portion of the porous material at the tapered end, rather than the capillary tube itself, forms the tip of the ESI emitter.
摘要:
During clinical trials on patients suffering from neurological disorders, it has been observed that some patients obtain dramatic improvements in motor control and/or higher mental functioning, when they receive a combination of dextromethorphan and quinidine, at suitable dosages. Improved motor control has been exemplified to date by improved ability to swallow and/or speak, among victims of stroke, head injury, or ALS. Improved higher mental functioning has been exemplified better job performance, increased ability to analyze and solve problems, and increased ability to have successful and satisfying interactions with other people. These types of effects can be seen in a relatively brief time period, such as within several days to a week.
摘要:
A colonoscopic device stabilizer for stabilizing a colonoscopic device when inserted in an anus of a patient. The stabilizer includes a body adapted for receipt within the anus of a patient. The body has an opening sized and shaped for receiving the colonoscopic device when the device is inserted in the anus of the patient. The stabilizer also includes a clamp attached to the body selectively moveable between a locked position in which the clamp resists movement of the colonoscopic device relative to the body and an unlocked position in which the clamp permits movement of the colonoscopic device relative to the body.
