The MRI apparatus may include a plurality of main magnetic coils arranged coaxially along an axis, a plurality of shielding magnetic coils arranged coaxially along the axis, and a cryostat in which the plurality of main magnetic coils and the plurality of shielding magnetic coils are arranged.

Abstract: A method for traffic flow classification in a communication network includes (1) identifying a traffic flow in communication network traffic, (2) extracting features of the traffic flow, and (3) using a machine learning model, classifying the traffic flow at least partially based on the features of the traffic flow. The features of the traffic flow include, for example, a distribution of packet size values of a sliding window sample of the traffic flow, a distribution of inter-arrival time values of a sliding window sample of the traffic flow, standard deviation of data packet size, average of data packet size, standard deviation of data packet inter-arrival time, and average of data packet inter-arrival time.

Abstract: A leakage compensation dynamic register, a data operation unit, a chip, a hash board, and a computing apparatus. The leakage compensation dynamic register comprises: an input terminal, an output terminal, a clock signal terminal, and an analog switch unit; a data latch unit for latching the data under control of the clock signal; and an output drive unit for inverting and outputting the data received from the data latch unit, the analog switch unit, the data latch unit, and the output drive unit being sequentially connected in series between the input terminal and the output terminal, and the analog switch unit and the data latch unit having a node therebetween, wherein the leakage compensation dynamic register further comprises a leakage compensation unit electrically connected between the node and the output terminal.

Abstract: Gas diffusion electrode suitable for use in carbon dioxide electrolyzer and methods for making the same. According to one embodiment, the gas diffusion electrode may include a gas diffusion layer and a catalyst layer coupled to the gas diffusion layer. The gas diffusion layer, in turn, may include an electron-conductive domain and a non-conductive hydrophobic domain. The electron-conductive domain includes a plurality of pores. The non-conductive hydrophobic domain randomly occupies a portion of the volume of the pores of the electron-conductive domain and is, itself, sufficiently porous to permit gas transport through the electron-conductive domain, for example, by incompletely filling the pores, thereby leaving spaces in the pores, and/or by being made of an inherently porous material. The electron-conductive domain may be in the form of a metal mesh, a carbon paper, or similar structures. The non-conductive hydrophobic domain may be in the form of sintered polymer particles.

Abstract: Embodiments for producing un-agglomerated, monodisperse droplets using a liquid sheet are provided. Nozzles with exit slit openings shape a spray liquid into a thin liquid sheet as the spray liquid exits from the slit opening. Stable multi-jet operation is achieved by including notches along the edge of the slit. The notches separate the liquid sheet into multiple jets to provide anchoring and stable multi jet operation.

Abstract: The invention relates to nickel-coated hexagonal boron nitride nanosheet composite powder, its preparation and high-performance composite ceramic cutting tool material. The composite powder has a core-shell structure with BNNS as the core and Ni as the shell. The self-lubricating ceramic cutting tool material is prepared by wet ball milling mixing and vacuum hot-pressing sintering with a phase alumina as the matrix, tungsten-titanium carbide as the reinforcing phase, nickel-coated hexagonal boron nitride nanosheet composite powder as the solid lubricant and magnesium oxide and yttrium oxide as the sintering aids. The invention also provides preparation methods of the nickel-coated hexagonal boron nitride nanosheet composite powder and the self-lubricating ceramic cutting tool material.
