Abstract: Methods for efficient doping of wide-bandgap (WBG) and ultrawide-bandgap (UWBG) semiconductors by implantation, and WBG and UWBG semiconductors made using the disclosed methods. A p-type semiconductor region is formed by implanting specified acceptor and donor co-dopant atoms in a predetermined ratio, e.g., two acceptors to one donor (ADA), into the semiconductor lattice. An n-type type semiconductor region is by implanting specified donor and acceptor co-dopant atoms in a predetermined ratio, e.g., two donors to one acceptor (DAD), into the semiconductor lattice. Compensator atoms are also implanted into the lattice to complete formula units in the crystal lattice structure and preserve the stoichiometry of the semiconductor material. The doped material is then annealed to activate the dopants and repair any damage to the lattice that might have occurred during implantation.

Abstract: Methods of collecting liquid samples are disclosed. According to some embodiments, a portion of a sample collection film is unrolled from a first reel to a position adjacent a sample dispenser. A liquid sample is dispensed from the sample dispenser onto the portion of the sample collection film. After dispensing the liquid sample onto the portion of the sample collection film, the portion of the sample collection film is rolled onto a second reel. Related sample collection devices, films, and reels are also disclosed.

Abstract: A method of making chalcogenide based polymeric materials and converting those materials into optical fiber preforms and polymeric optical fibers. The preforms and fibers comprise chalcogenide elements and crosslinking moieties. These fibers can be used as optical waveguides at infrared wavelengths where other polymer fibers do not operate. The optical waveguides are ideally suitable for applications requiring the transmission of low-power infrared light, but may also be useful for transmitting high-power light at visible or infrared wavelengths.

Abstract: A method that includes receiving a set of one or more images, each having one or more sets of pixels, receiving a ground truth value that a vertex point associated with a transition between two regions in a respective set of pixels, identifying a machine placement candidate vertex point for a first set of pixels, determining a set of one or more selected candidate features in the set of candidate features that maximizes an objective function that identifies an accuracy of the identified machine placement candidate vertex point compared to the respective ground truth for a respective set of pixels, updating a set of one or more basis features by adding the set of one or more selected candidate features that maximizes the objective function, and training a machine learning model based on the updated set of one or more basis features to identify additional vertex points for a transition.

Abstract: One can enrich nucleic acid (RNA or DNA) from within a complex mixture in a sequence-specific manner by using a mutant of a Cas enzyme lacking nuclease activity, for example a mutant of Cas13a (dCas) from Leptotrichia wadeii. The nucleic acid is bound by the mutant protein as directed by guide RNA molecules (crRNA) and purified after association with an appropriate surface, such as quantum dots or functionalized beads. The nucleic acid is separated from the Cas and purified after precipitation or interaction with another surface. The resulting product can be directly processed via long-read sequencing.

Abstract: A method of making an electrode by providing a mixture of first particles of silver or silver oxide and second particles of an inorganic porogen, molding the mixture, cohering the mixture to form a green body, demolding the green body, heating the green body to form a monolith, to convert any silver oxide to silver, and to fuse the first particles together, and submerging the monolith in a liquid that removes the second particles.
