Abstract: An apparatus and method for measuring three-dimensional radiation dose distributions with high spatial and temporal resolution using a large-volume scintillator. The scintillator converts the radiation dose distribution into a visible light distribution. The visible light is transported to one or more photo-detectors, which measure the light intensity. The light signals are processed to correct for optical artifacts, and the three-dimensional light distribution is reconstructed. The reconstructed light distribution is post-processed to convert light amplitudes to measured radiation doses. The high temporal resolution of the detector makes it possible to observe the evolution of a dynamic dose distribution as it changes over time. Integral dose distributions can be measured by summing the dose over time.

Abstract: A method includes receiving toolface information corresponding to a location of the bottom hole assembly (BHA) with respect to a target drilling path and drift information. The surface steerable system calculates a first toolface vector from a first location of the BHA to the target drilling path to create a convergence path to the target drilling path and calculates an adjustment of the first toolface vector to a second toolface vector to account for system drift defined by the drift information such that the BHA will converge with the target drilling path by drilling in accordance with the second toolface vector. The surface steerable system modifies at least one drilling parameter to alter a drilling direction of the BHA based on the calculated second toolface vector and transmits the at least one drilling parameter to the drilling rig to target the BHA in accordance with the second toolface vector.

Abstract: Compositions and methods of synthesis of anionic surfactants by alkoxylation of a Guerbet alcohol (GA) having 12 to 36 carbon atoms using butylene oxide, and optionally propylene oxide and/or ethylene oxide followed by the incorporation of a terminal anionic group are described herein. The GA of the present invention is made by a facile and inexpensive method that involves high temperature base catalyzed dimerization of alcohols with 6 to 18 carbon atoms. The large hydrophobe ether surfactants of the present invention find uses in enhanced oil recovery (EOR) applications where it is used for solubilization and mobilization of oil and for environmental cleanup. Further, the hydrophobe alkoxylated GA without anionic terminal group can be used as an ultra-high molecular weight non-ionic surfactant.

Abstract: A method and apparatus for detects one or more subsurface targets by receiving a reflectivity data from two or more subsurface reflectors using a ground penetrating radar. The two or more subsurface reflectors may include the one or more subsurface targets and a medium surrounding the one or more subsurface targets. An impedance data for the two or more subsurface reflectors is calculated by inverting the reflectivity data using a temporal transmission line model with a “layer-peeling” method. One or more constitutive parameters of the two or more subsurface reflectors are calculated based on the impedance data. The one or more subsurface targets are detected based on a change in the one or more constitutive parameters.

Abstract: A method, system and computer program product for efficiently identifying images, videos, audio files or documents relevant to a user. Using either manual annotations or learned functions, the method predicts the relative strength of an attribute in an image, video, audio file or document from a pool of images, videos, audio files or documents. At query time, the system presents an initial set of reference images, videos, audio files or documents, and the user selects among them to provide relative attribute feedback. Using the resulting constraints in the multi-dimensional attribute space, the relevance function for the pool of images, videos, audio files or documents is updated and the relevance of the pool of images, videos, audio files or documents is re-computed. This procedure iterates using the accumulated constraints until the top-ranked images, videos, audio files or documents are acceptably close to the user's envisioned image, video, audio file or document.

Abstract: A spintronic device and a method for making said spintronic device. The spintronic device includes an epitaxial crystalline ferromagnetic oxide formed directly on the semiconductor material thereby allowing spin-polarized current to be efficiently injected from the ferromagnetic oxide into the semiconductor material. A host crystal lattice includes multiple sets of stacked oxide layers of material A and B of a perovskite structure with a formula of ABO3. After an oxide layer of B is grown, magnetic ions are introduced to intermix with the B material, which may replace some of the ions of the B material. The process of growing additional stacked oxide layers of material A and B and introducing further magnetic ions after the deposition of the oxide layer of B continues until enough magnetic ions are sufficiently close to one another that they align in the same direction thereby forming a ferromagnetic oxide on the semiconductor material.

Abstract: A vertical-mode tunnel field-effect transistor (TFET) is provided with an oxide region that may be laterally positioned relative to a source region. The oxide region operates to reduce a tunneling effect in a tunnel region underlying a drain region, during an OFF-state of the TFET. The reduction in tunneling effect results in a reduction or elimination of a flow of OFF-state leakage current between the source region and the drain region. The TFET may have components made from group III-V compound materials.
