    摘要: A method for calibrating a radiation detection medium by exposing arbitrary locations of a radiation detection medium to a plurality of known radiation dose levels is described. One particular aspect of the method includes the steps of automatically determining the location of each arbitrary exposed location, measuring the density of each of the arbitrary exposed locations, matching each measurement for the arbitrary exposed locations with the corresponding radiation dose level thereby generating an array of paired data values for radiation dose level and measured density and calculating a calibration based on the array of paired data values.

    摘要: A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer is grown by anodising at a voltage between 50 and 150 V, and the biocidal material incorporated in it by ion exchange. This produces a significantly harder surface than anodising at low voltage, and generates pits containing ion-absorbing material.

    摘要: A method and apparatus of defining a time interval includes providing a source of ionizing radiation that radiates emissions thereof; placing a radiation sensitive display material responsive to ionizing radiation in a close proximity relationship to the source of ionizing radiation whereby the radiated emissions of the source strike the radiation sensitive display material, thereby commencing a time interval; and, measuring changes in characteristics of the radiation sensitive display material that are indicative of the elapsed time.

    摘要: Endogenous gene regulation mechanisms together with microRNAs expressed in many organisms can be used to provide regulated or conditional expression of transgenes by placing an appropriate sequence, a microRNA binding site, within the transcribed gene. This microRNA-dependent transcription regulation can be further regulated using microRNA inhibitors.

    摘要: An article of manufacture comprising a radiation sensitive material, and a measuring scale that is part of the radiation sensitive material. A method of measuring at least one parameter relating to an irradiated material is also described. A radiation sensitive material including a measuring scale is exposed to radiation and at least one parameter relating to one or more exposed areas of the material is measured by reference to the measuring scale on the material.

    摘要: A logic device logic module includes multi-stage combinational logic circuitry (e.g., a four-input look-up table) into which EXCLUSIVE OR (“XOR”) circuitry is interposed to give the logic module arithmetic as well as combinational logic capabilities. The XOR circuitry is used to help form an arithmetic sum output signal (as an alternative to a combinational logic output signal) when arithmetic mode operation is desired. The logic module is also augmented with circuitry for providing a carry out signal in arithmetic mode. The logic module can perform such arithmetic operations as one digit or bit of binary addition, subtraction, or multiplication. In all cases a carry in signal is taken into account; and in the case of multiplication, a digit from another partial product or summation of other partial products is also taken into account.

    摘要: In vivo endogenous microRNA (miRNA) activity can be observed over time using miRNA sensor plasmids capable of long term expression. Using reporter genes whose expression can be monitored without sacrificing the animal enables the investigator to follow changes in miRNA expression though developmental stages or in response to environmental factors or treatment regimens.
