  • Patent number: 11993864
    Abstract: A method for forming a silicon carbide material with a plurality of negatively charged silicon mono-vacancy defects includes irradiating a silicon carbide sample, annealing the irradiated silicon carbide sample in an annealing operation, and quenching the annealed silicon carbide sample. Quenching may include heating the annealed silicon carbide sample to a maximum temperature and quenching the annealed silicon carbide sample to form the silicon carbide sample with the plurality of negatively charged silicon mono-vacancy defects.

  • Publication number: 20240079092
    Abstract: Systems and methods for subject clinical condition evaluation using a plurality of modules are provided. Modules comprise features whose corresponding feature values associate with an absence, presence or stage of phenotypes associated with the clinical condition. A first dataset is obtained having feature values, acquired through a first technical background from respective subjects in transcriptomic, proteomic, or metabolomic form, for at least a first of the plurality of modules. A second training dataset is obtained having feature values, acquired through a technical background other than the first technical background, from training subjects of the second dataset, in the same form as for the first dataset, of at least the first module. Inter-dataset batch effects are removed by co-normalizing feature values across the training datasets, thereby calculating co-normalized feature values used to train a classifier for clinical condition evaluation of the test subject.

  • Patent number: 9273703
    Abstract: An orientation-independent electro-hydraulic actuator that includes a housing having an interior space forming a fluid reservoir, a pump connected to the housing, an electric motor drivingly coupled to the pump; and a piston-cylinder assembly having a piston axially movable within a cylinder. The cylinder is in fluid communication with the pump to effect movement of the piston in response to fluid flow between the cylinder and the fluid reservoir. The pump has one or more inlet/outlet ports communicating with a volumetric centroid region of the fluid reservoir. The fluid reservoir includes a volume of hydraulic fluid such that when the piston is fully extended, the volume of fluid in the reservoir is at a minimum and at least one of the inlet/outlet ports is submerged in hydraulic fluid.
