  • Publication number: 20240076458
    Abstract: A process to form a rheology modified composition, the process comprising applying radiation, and optionally heat, to a composition that comprises at least the following component: a) an olefin-based polymer comprising a total unsaturation ?0.20 /1000 C; and wherein the radiation is applied using an electron beam (e-beam) at a dosage selected from 0.1 MRad to 1.5 MRad; and wherein component a is selected from a telechelic polyolefin of the formula A1L1L2A2, an unsaturated polyolefin of the formula A1L1, or an ethylene/alpha-olefin interpolymer. A process to form a rheology modified composition, the process comprising applying heat, and optionally radiation, to a composition that comprises at least the following components: a) an olefin-based polymer, as described above, comprising a total unsaturation ?0.20/1000 C; b) from 1.0 to 100 ppm of a peroxide, based on the weight of the composition.

  • Patent number: 11786215
    Abstract: Systems and methods for monitoring and controlling delivery of a therapeutic compound to a brain of a subject using FUS-BBBD are disclosed. The method includes treating the brain of the subject with focused ultrasound in combination with microbubbles for blood-brain barrier disruption (FUS-BBBD), administering the therapeutic agent to the subject; and obtaining a map of a concentration of the therapeutic agent delivered to the brain of the subject using passive cavitation imaging (PCI). The delivery of focused sound may be modulated to match the map of the concentration of the therapeutic agent delivered to the brain of the subject to a desired spatial distribution of the therapeutic agent.

  • Publication number: 20230085020
    Abstract: A method for testing a cell site during or after construction of the cell site is provided. In various embodiments, the method is implemented by a processor on a computing platform associated with a field technician. In those embodiments, the method includes pre-test configuration and connection, RU-testing, UE-testing, and post testing actions. In the pre-test configuration and connection, a connection is made with one or more cell site routers, and computing platform configures the cell site routers for the testing. In the RU-testing, one or more RUs are connected via the CSR, connections of the RU(s) and antennas connected to the RUs are tested. In the UE-testing, the field technician is instructed to perform various sector tests to test downlink connections between the UE and the RUs.

  • Patent number: 8562849
    Abstract: Methods and apparatus for processing edge portions of a donor semiconductor wafer include controlling chemical mechanical polishing parameters to achieve chamfering of the edges of the donor semiconductor wafer; and alternatively or additionally flexing the donor semiconductor wafer to present a concave configuration, where edge portions thereof are pronounced as compared to a central surface area thereof, such that the pronounced edge portions of the donor semiconductor wafer are preferentially polished against a polishing surface in order to achieve the chamfering.

  • Publication number: 20070286331
    Abstract: Motion artifacts and patient dose during 4D CT imaging are reduced by adaptive control of data acquisition. The respiration signal (310) and CT data acquisition (340) are linked, such that ‘bad’ data from erratic breathing cycles that cause artifacts is not acquired by pausing CT data acquisition (360) when erratic breathing is detected, and not resuming CT data acquisition until steady-state respiration is resumed. Training data is used to develop a tolerance envelope for a respiratory signal such that for erratic breathing cycles the respiratory signal is not within the tolerance envelope (330).

  • Publication number: 20060056951
    Abstract: A material handling system for placing and retrieving palletized loads in densely spaced storage areas utilizing an overhead bridge crane connected to a pallet load handling device by way of lifting cables and a stabilizing mast assembly. The pallet handling devices may include vertically or horizontally movable pallet engaging fork mechanisms mounted on a generally rectangular frame which is operable to be lowered over a pallet load and engaged therewith by way of the fork mechanisms. The pallet handling device frame may be split and interconnected by actuator mechanisms to facilitate ease of placing the handling devices over a pallet load and releasing the load from the handling device.

  • Publication number: 20060011540
    Abstract: The invention relates generally to a process and apparatus for treating biosolids resulting from the treatment of biological wastewater streams. The invention relates to autothermal aerobic treatment of biosolids where temperature is controlled by sensing the oxidation/reduction potential of a treated solution and adjusting the amount of oxygen or the amount of biosolids supplied to the solution. The invention provides for a truly aerobic environment under which thermophilic microorganisms will thrive.

  • Publication number: 20050042280
    Abstract: The present invention is directed to aqueous based formulations of water-soluble prodrugs of propofol. The formulations comprise in aqueous medium an effective amount of the water-soluble prodrug of propofol and an effective amount of an antioxidant. In one embodiment, the formulation also contains a tonicity modifier. The formulations are particularly useful as intravenous injections. The formulations preferably are buffered to a pH suitable for minimizing degradation of the prodrug during storage. Advantageously, the formulations can be prepared without the use of harmful co-solvents or surfactants, and are stable at room temperature over extended periods of time.
