Systems and methods treat produce on vines or in fields with hydroxyl-radical treatments and provide antimicrobial hydroxyl-radicals of the hydroxyl-radical treatments by exposing hydrogen peroxide mist and/or ozone gas within a process chamber to UV-C light and/or radiation emitted by one or more UV-C lamps. The methods treat the produce on the vines or in the fields with the one or more hydroxyl-radicals of the hydroxyl-radical treatments by moving the systems over, above, and/or around the produce on the vines or in the fields. The systems have a movable frame, at least one mist producing unit in fluid communication with the processing chamber, one or more UV-C lamps disposed within or adjacent to the processing chamber, and at least one ozone gas producing unit in fluid communication with the processing chamber.

This present disclosure involves a multi-arm beam codebook design and training method for near-field wireless communications, comprising: modeling near-field channels and signals based on a spherical wave assumption for both linear antenna arrays and planar antenna arrays; sampling angles for steering vectors at equal intervals; forming a polar domain transformation matrix from the near-field steering vectors; constructing a near-field single-arm beam codebook; obtaining a near-field hashing multi-arm beam training codebook through a hash function; and determining a matching single-arm beam codeword by a soft decision and voting mechanism. This method, under near-field electromagnetic radiation conditions, demonstrates better applicability with the designed near-field hashing multi-arm beam training codebook compared to far-field codebooks, with a significant improvement in identification accuracy and training overhead compared to the hierarchical training.

A method for constructing and controlling a turbulence form of a fluid inside a reactor pressure vessel. The method comprises: step S1, obtaining related data of vortexes, a temporal distribution characteristic, a spatial distribution characteristic and a power spectral density of turbulence in an inlet area of each fuel assembly, and a turbulence energy spectrum; step S2, obtaining a water gap change situation of each fuel assembly, and on the basis of the water gap change situation of each fuel assembly, determining whether a three-dimensional flow field model of each fuel assembly needs to be corrected, until a water gap of each fuel assembly does not change; step S3, obtaining a reactor core nuclear power fluctuation amplitude value between fuel assemblies; and step S4, determining whether the reactor core nuclear power fluctuation amplitude value falls within a target range, and if the reactor core nuclear power fluctuation amplitude value does not fall within the target range, changing a three-dimensional structure inside a reactor pressure vessel until the reactor core nuclear power fluctuation amplitude value falls within the target range. The method for constructing and controlling a turbulence form of a fluid inside a reactor pressure vessel can eliminate or ameliorate the nuclear power fluctuation of a reactor core, reduce the wear of grids of the reactor core, and ensure the safety of reactor operation.

A high-strength non-magnetic austenitic stainless steel bar suitable for a nuclear fusion armor and a manufacturing method therefor. High-temperature δ-ferrite and MC are eliminated from the high-strength non-magnetic austenitic stainless steel bar, and therefore the steel bar achieves a good match between strength and toughness at a low temperature, and also has good resistance to intercrystalline corrosion. At a liquid helium temperature of 4.2 K, the high-strength non-magnetic austenitic stainless steel bar has a yield strength greater than or equal to 1250 MPa, a tensile strength greater than or equal to 1700 MPa, an elongation greater than or equal to 25%, and a magnetic conductivity smaller than or equal to 1.02. The high-strength non-magnetic austenitic stainless steel bar can be directly used in a structural member such as a conductor armor in a fusion reactor and other nuclear reaction devices, and can also be promoted and used in other related fields such as high-strength stainless parts required in cryogenic engineering.

The invention relates to a magnetic resonance imaging radiation therapy system with reduced interference to the therapeutic radiation. The system includes: a magnetic resonance imager (110) comprising a magnet (120) enclosing a bore (130); a radiation therapy device (140) configured to radiate, from multiple positions about a longitudinal axis (150) of the bore, a therapeutic beam (160) with respective radial beam paths towards the bore (130); a coldhead (170) positioned outside of the beam paths; and a thermally conducting cooling segment (180) in thermal connection with the coldhead (170). The cooling segment (180) is extending azimuthally about the longitudinal axis (150) of the bore. The cooling segment (180) is positioned to intersect with the beam paths, and a width (w)of the cooling segment is larger than a maximum width of the therapeutic beam (180). Preferably, attenuation of the therapeutic beam (160) by the cooling segment (180) is constant between the respective beam paths from different positions about the longitudinal axis (150) of the bore.
