Abstract: A method and device for accurately determining oxygen saturation of hemoglobin by the measurement of the optical density of a sample, such as a blood vessel, in response to illumination by light having at least three wavelengths (?1, ?2, ?3, . . . ) within a range of about 460 nm to about 523 nm. The hematocrit of a sample may be determined from optical density measurements at the three or more wavelengths in conjunction with a known path length. The device may be an intravenous or intra-arterial fiber optic catheter used to deliver the interrogating light signal to the blood and to detect the reflected signal. A method and device of determining the thickness of the retinal well using spectroscopic information are also disclosed.

Abstract: A passive wireless gastroesophageal sensor includes a LC resonance circuit, two or more electrodes and a passive batteryless Radio Frequency Identification (RFID) circuit connected to the LC resonance circuit and the one or more electrodes. The electrodes are configured to measure an impedance within a gastroesophageal tract. The passive batteryless RFID circuit transmits a frequency modulated signal using the LC resonance circuit that varies between a first frequency corresponding to a non-acid reflux condition and a second frequency corresponding to an acid reflux condition based on the measured impedance in response to a signal received from a detector.

Abstract: A domain model generator (DMG) for an integrated development environment (IDE) guides a software engineer through a process of identifying domain-specific concepts for a domain of an object-oriented software application. The DMG also helps the engineer to classify the domain-specific concepts as pertaining to particular object-oriented modeling concepts for the object-oriented software application. Those modeling concepts may include classes, attributes, inheritance, etc. In addition, the DMG may automatically generate a Unified Modeling Language (UML) domain diagram, based at least in part on the domain-specific concepts and the corresponding modeling concepts. Other embodiments are described and claimed.

Abstract: Systems, methods and devices which utilize Spread Spectrum Time Domain Reflectometry (SSTDR) techniques to measure degradation of electronic components are provided. Such measurements may be implemented while the components “live” or otherwise functioning within an overall system. In one embodiment, monitoring a power converter in a high power system is accomplished. In this embodiment, degradation of components within the power converter (e.g. metal-oxide-semiconductor field-effect transistors (MOSFETs), capacitors, insulated-gate bipolar transistors (IGBTs), and the like) may be monitored by processing data from reflections of an SSTDR signal to determine changes in impedance, capacitance, or any other changes that may be characteristic of components degrading. For example, an aging MOSFET may experience an increase of drain to source resistance which adds additional resistance to a current path within a power converter.

Abstract: A three-dimensional nanobattery formed by individually wiring nanostructured electrodes and combining them with an electrolyte. Short, capped nanotubes termed ‘nanobaskets’ are formed by sputtering coating onto nanoporous templates. Metallic nanowires are grown by electrochemical deposition from the nanobaskets and through the template, making electrical contact with each nanobasket electrode. The same procedure can be used to fabricate both a battery anode and a battery cathode. A thin layer of electrolyte is placed between the two nanobasket electrodes, and electrical contact is made through the nanowires.

Abstract: During lung injury, p53 expression increases, inducing plasminogen activator inhibitor-1 (PAI-1) while inhibiting expression of urokinase-type plasminogen activator (uPA) and its receptor (uPAR), resulting in apoptosis of lung epithelial cells (LECs). In the bleomycin lung injury model, p53 and PAI-1 are induced while uPA and uPAR are inhibited. A 20 residue peptide DGIWKASFTTFTVTKYWFYR termed PP-1 (the Cav-1 scaffolding domain) or peptide NYHYLESSMTALYTLGH, termed PP-2, protected LECs from bleomycin-induced apoptosis in vitro and in vivo and prevented subsequent pulmonary fibrosis by attenuating lung epitheilial damage. Pharmaceutical compositions, peptide multimers and deliverable polypeptides comprising the above peptides are dislcosed.
