  • Publication number: 20220160888
    Abstract: The presented invention relates to a CP2c-targeting peptide-based anticancer agent. A CP2c-targeting peptide according to the presented invention binds to transcription factor CP2c to inhibit the formation of transcription factor CP2c complexes (CP2c homotetramer and CP2c/CP2b/PIAS1 heterohexamer), thereby inducing cancer cell-specific cell death. A fatty acid is bound to the peptide to ensure stability enabling long-term sustenance in vivo.

  • Publication number: 20190365292
    Abstract: An acoustic otoscope generates volume change excitations of either a trapezoidal or sinusoidal waveforms which are coupled into a sealed ear canal using a speculum tip. The change in volume results in a pressure change, for which a pressure measurement is taken during the volume change excitation interval. In one example, a trapezoidal time-domain volume change is presented, and a pressure measurement waveform is stored, the pressure measurement waveform thereafter examined to find a change of slope point in time, after which the pressure measurement waveform is scaled to be equal to the volume change waveform at that same point in time, a difference between scaled pressure measurement and volume excitation is formed, and examined for peak value prior to the earlier determined change in slope point in time.

  • Patent number: 8964876
    Abstract: A method of compensating for an error and a transceiver system using the method. The method includes determining whether a distortion occurs in data received by a receiving unit; if it is determined that the distortion occurs in the received data, changing at least one of a plurality of transmission parameters of the received data by one step; transmitting the received data using the changed at least one transmission parameter in a transmitting unit; and repeatedly performing the determining, the changing, and the transmitting until it is determined that the distortion does not occur in the received data.

  • Publication number: 20130206712
    Abstract: A solar concentrator assembly includes a pair of rails coupled together only by one or more backpans which are mounted between the pair of rails. The rails are configured to resist a portion of a cantilever deflection along the length of the rails. The backpans seat solar concentrator arrays and are configured to provide torsional rigidity and deflection resistance in at least one direction orthogonal to the cantilever deflection.

  • Patent number: 6916399
    Abstract: The present invention provides a temperature controlled energy transparent window or electrode used to advantage in a substrate processing system. The invention also provides methods associated with controlling lid temperature during processing and for controlling etching processes. In a preferred embodiment the invention provides a fluid supply system for the lid which allows the fluid to flow through a feedthrough and into and out of a channel formed in the window or electrode. The fluid supply system may also mount the window or electrode to a retaining ring which secures the window or electrode to the chamber. In another aspect the invention provides a bonded window or electrode having a first and second plate having a channel formed in the plates so that when the plates are bonded together they form a channel therein through which a temperature controlling fluid can be flowed. An external control system preferably regulates the temperature of the fluid.

  • Patent number: 5838349
    Abstract: A method for electrohydrodynamic printing wherein multiple colors are printed by discharging the receiving medium by reverse-sign corona discharge, then charging the receiving medium by corona discharge, and then printing the first color. The receiving medium is then discharged, and charged a second time by corona discharge. The process is repeated for each color used in the printing. As a result, the colors are printed in their intended locations without deflection even if the intended location is a dot of previously deposited color.
