Abstract: The luminance of a transmission mode X-ray scintillator diamond plate is dominated by induced defect centers having an excited state lifetime less than 10 msec, and in embodiments less than 1 msec, 100 usec, 10 used, 1 used, 100 nsec, or even 50 nsec, thereby providing enhanced X-ray luminance response and an X-ray flux dynamic range that is linear with X-ray flux on a log-log scale over at least three orders of magnitude. The diamond plate can be a single crystal having a dislocation density of less than 104 per square centimeter, and having surfaces that are ion milled instead of mechanically polished. The defect centers can be SiV centers induced by silicon doping during CVD diamond formation, and/or NV0 centers formed by nitrogen doping followed by applying electron beam irradiation of the diamond plate and annealing.

Abstract: A novel electrode current collector design that can improve performance and extend cycle life for rechargeable batteries based on metal electrodeposition is disclosed. The novel electrode current collector has a reduced effective surface area that can help to balance efficiencies between battery electrodes and to ensure non-uniform electrodeposition of metal onto the anode current collector during charge. One result is mitigation of internal short circuits that can cause a battery to fail prematurely.

This can allow the ion selective layer to be configured to selectively block zincate ions.

Abstract: In one embodiment, the invention provides a method of purifying recombinant alpha-galactosidase A. The method includes obtaining a lysate from cells recombinantly expressing alpha-galactosidase A grown in a cell culture medium having non-precipitating phosphate; contacting said lysate with a first chromatography media that binds ?-D-mannopyranosyl or ?-D-glucopyranosyl; eluting alpha-galactosidase A from the first chromatography media to generate a first eluate having alpha-galactosidase A, wherein said eluting includes at least one elution pause between 4 and 16 hours; contacting the first eluate with a second chromatography media that binds galactose binding proteins; and eluting alpha-galactosidase A from said second chromatography media to generate a second eluate containing said recombinant alpha-galactosidase A.

Abstract: A device for generating singlet oxygen is provided. The device has elongated posts extending from a surface, the lateral sides of which have particles with a sensitizer that converts triplet oxygen to single oxygen upon exposure to light. An optical fiber conveys light to the sensitizer and a gas supply tube conveys oxygen to the sensitizer. The device is configured to keep the sensitizer from contacting external fluids, such as saliva.

Abstract: Described herein is a chelator for radiolabels (e.g., 89Zr) for targeted PET imaging that is an alternative to DFO. In certain embodiments, the chelator for 89Zr is the ligand, 3,4,3-(LI-1,2-HOPO) (“HOPO”), which exhibits equal or superior stability compared to DFO in chemical and biological assays across a period of several days in vivo. As shown in FIG. 1, the HOPO is an octadentate chelator that stabilizes chelation of radiolabels (e.g., 89Zr). A bifunctional ligand comprising p-SCN-Bn-HOPO is shown in FIG. 4 and FIG. 5. Such a bifunctional ligand can eliminate (e.g., 89Zr) loss from the chelate in vivo and reduce uptake in bone and non-target tissue. Therefore, the bifunctional HOPO ligand can facilitate safer and improved PET imaging with radiolabeled antibodies.

Abstract: A method of inducing spin polarization in an analyte is provided. The method exposes 14N spin defect centers embedded within 25 nm of a diamond surface to a magnetic field while an analyte is near the surface. The 14N spin defect centers are polarized by treatment with an electromagnetic wave protocol having a visible light pulse (p0); a microwave pulse (mw1), a radio frequency pulse (rf1), a microwave pulse (mw2) and a radio frequency pulse (rf2) resulting in polarization of the nuclear spins of the 14N spin defect centers. Polarized spins in the 14N spin defect centers induce spin polarization in the analyte.

Abstract: Nanocages are formed by etching nancubes. The nanocubes are added to an aqueous system having an amphiphilic lipid dissolved in an organic solvent (e.g. a hydrophobic alcohol) to form reverse micelles. As the water evaporates the micelles shrink as etching of the flat surface of the nanocubes occurs. In this fashion hollow nanocages are produced. In one embodiment, the nanocage is covalently attached to a polymer shell (e.g. a dextran shell).

Abstract: A method for detecting intrusion is provided using a combination of two AIS algorithms: Negative Selection Algorithm (NSA) and Dendritic Cell Algorithm (DCA). The method includes the following steps, or some functional subset of these steps: periodic monitoring of a data processing system for anomalous behavior that may indicate the presence of an intruder or an undesirable software; using the NSA for the generation of a population of detectors that are used for detecting anomalies in the monitored system via a matching criterion; using the DCA (which runs in parallel to the NSA) to sample traffic and signals coming in or out of the data processing system; using an aggregation system to combine the individual decisions of the NSA and the DCA to form a single final decision.

The length, width, and height of the nanoparticles may be less than 100 nm. The methods may further comprise distributing the nanoparticles on the substrate to produce a film. The nanoparticles in the film may be coupled nanoparticles. The coupled nanoparticles may be in disordered contact with each other within the film. The distribution may be performed such that constructive interference of the light occurs by multiple scattering at the boundaries of the coupled nanoparticles within the film. The methods may comprise exposing the film to a power source.

Abstract: A robotic device for providing vertical mobility has a payload is disposed inside a central compartment and supported by a skid. The skid can move up and down through latch and hook pairs to keep intimate contact with the surface and cross over bumps. The apparatus uses a flexible seal to create a reliable vacuum chamber. The flexible seal comprises a foam ring inside fabric pocket. A plurality of rod and spring strips are configured to apply a downward force to the flexible seal to conform with surface curvatures. The fabric pocket fills in the gaps or seams to maintain a vacuum. The air flows inside a manifold and passes through a filter to avoid debris from damaging the vacuum motor assembly.

Abstract: A genetically modified vertebrate is provided that has an enhanced sense due to an over representation of a predetermined odorant receptor. The vertebrate is genetically modified by introduction of DNA that comprises at least four sequential repeats of a sequence whose primary structure is at least 90% homologous with ACATAACTTTTTAATGAGTCT (SEQ ID NO: 1). The DNA causes a nearby odorant receptor coding sequence to be over represented in a singular gene choice fashion relative to a corresponding vertebrate that lacks the DNA.
