  • Patent number: 9396916
    Abstract: An electrokinetic pump can be used to deliver calibrant (“lock mass”) ions to a mass spectrometer for calibration of a mass spectrometry system. Electrokinetically controlled calibrant delivery can help to eliminate the need for the more cumbersome mechanisms that are often used for ion delivery. In addition, electrokinetically controlled calibrant delivery can provide for a more user-friendly system in which a calibrant solution can be packaged into a disposable cartridge. Furthermore, when implemented in a microfluidic format, electrokinetically controlled calibrant delivery can be coupled with an electrokinetically controlled separation system, such as capillary electrophoresis (CE), to allow efficient solid-state switching between analytical and calibrant sprays.

  • Patent number: 9244180
    Abstract: Large-area, flat-panel photo-detectors with sub-nanosecond time resolution based on microchannel plates are provided. The large-area, flat-panel photo-detectors enable the economic construction of sampling calorimeters with, for example, enhanced capability to measure local energy deposition, depth-of-interaction, time-of-flight, and/or directionality of showers. In certain embodiments, sub-nanosecond timing resolution supplies correlated position and time measurements over large areas. The use of thin flat-panel viewing radiators on both sides of a radiation-creating medium allows simultaneous measurement of Cherenkov and scintillation radiation in each layer of the calorimeter. The detectors may be used in a variety of applications including, for example, medical imaging, security, and particle and nuclear physics.

  • Patent number: 9222881
    Abstract: The present invention relates to systems and methods for the determination of the secondary structure composition of proteins using coherent two-dimensional infrared (2DIR) spectroscopy of backbone amide I vibrations (1580-1720 cm?1). Fractions of ?-helix, ?-sheet, and unassigned regions in globular proteins were determined by singular value decomposition using basis spectra from sixteen commercially-available proteins with known crystal structures. Preferred methods included removing each protein from the set and comparing the predicted composition against the crystal structure. The root-mean-squared (RMS) errors of the predicted secondary structure compositions were found to be 7.9% for ?-helix, 5.5% for ?-sheet, and 7.6% for unassigned regions. The structure analysis can also be performed using one-dimensional absorption spectra and the RMS errors are compared with those obtained from 2DIR.

    Abstract: The electrical charging by a primary electronic is inhibited to produce a clear edge contrast from an observation specimen (i.e., a specimen to be observed), whereby the shape of the surface of a sample can be measured with high accuracy. An observation specimen in which a liquid medium comprising an ionic liquid is formed in a thin-film-like or a webbing-film-like form on a sample is used. An electron microscopy using the observation specimen comprises: a step of measuring the thickness of a liquid medium comprising an ionic liquid on a sample; a step of controlling the conditions for irradiation with a primary electron on the basis of the thickness of the liquid medium comprising the ionic liquid; and a step of irradiating the sample with the primary electron under the above-mentioned primary electron irradiation conditions to form an image of the shape of the sample.

  • Patent number: 9188685
    Abstract: A stacked type of radiation detector and a calibration method that enables the radiation detector to correct variations in sensor-specific output easily and within a short time, without using a water-phantom dose detector.

A dummy absorber has water-equivalent thickness equal to an average water-equivalent thickness of the sensors. A signal-processing unit calculates sensor-specific calibration coefficients using a measurement result obtained during irradiation of the radiation detector with the radiation when electrical signals developed in each sensor are measured, and a measurement result obtained during irradiation of the radiation detector with the radiation when the sensor section is moved in the traveling direction of the radiation, then the dummy absorber is set in place, and electrical signals developed in each sensor are measured.

  • Patent number: 9176237
    Abstract: In a coincidence determination of a PET device, the PET device uses a scintillator of radioactive isotope containing background noise due to intrinsic radioactivity as a radiation detector. The PET device counts a pair of annihilation radiations that is assumed to occur from a same nuclide. The annihilation radiations are detected within a predetermined coincidence time window by a plurality of radiation detectors. The method includes determining a coincidence with a wide energy window that allows detecting the background noise due to intrinsic radioactivity as multiple coincidences; removing the multiple coincidences; and using an energy window narrower than the wide energy window to limit a coincidence event to a coincidence event in a photopeak from a positron nuclide only.
