  • Publication number: 20250193549
    Abstract: A device for generating an X-ray image is provided. The device obtains first and second sets (350-(t?1), 350-t) of pixel frame data from readouts of sensor pixels (SP1-SPN) at first and second times (t?1, t). The sensor pixels are spatially offset from one another by a first distance (dy) in a sensor scanning direction (y). Between the first and second times, an object point-projection (122a, 122b) on the sensor has had time to move a distance (h) greater than the first distance. A first data element (Li(t?1)) of the first set is combined (236) with a second data element (Li(t)) of the second set, wherein the first and second data elements are associated with different sensor pixels, to generate (part of) the image 400. A corresponding X-ray detector, imaging system and method are also provided.

The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.

  • Publication number: 20230046064
    Abstract: A computer-implemented method comprises generating computer executable code as one or more code portions; detecting a number of processing operations required to reach one or more predetermined stages in execution of each code portion; and associating with each code portion one or more progress indicators, each representing a respective execution stage of the one or more predetermined stages within execution of that code portion. The code portions are executed by a processor powered by an unpredictable power source. When the processor detects an energy condition indicating that no more than a reserve quantity of electrical energy is available, the progress indicators are used to determine whether or not to perform a checkpoint.

  • Patent number: 11183312
    Abstract: A method for treating a fluid waste, comprising adding one or more process additives to the fluid waste in an amount sufficient to change the wasteform chemistry is disclosed. The addition step may be chosen from adding a dispersant or a deflocculant an additive to decrease the reactive metal components, to bind fission products and decrease volatilization of toxic or radioactive elements or species during thermal treatment, or to target and react with the fine particle size component of the waste to decrease dusting and immobilize components in a durable phase. After mixing the fluid waste with the described additives the waste is eventually hot-isostatic pressing, to form a durable and stable waste form.
