Abstract: An all-printed physically unclonable function based on a single-walled carbon nanotube network. The network may be a mixture of semiconducting and metallic nanotubes randomly tangled with each other through the printing process. The unique distribution of carbon nanotubes in a network can be used for authentication, and this feature can be a secret key for a high level hardware security. The carbon nanotube network does not require any advanced purification process, alignment of nanotubes, high-resolution lithography and patterning. Rather, the intrinsic randomness of carbon nanotubes is leveraged to provide the unclonable aspect.

Abstract: Method for high throughput, highly reproducible, direct write plasma jet deposition of organic electronic materials through nozzles containing non-concentric tubes with inner tube having higher dielectric constant and/or higher wall thickness than the outer tube, so that the inner tube containing the aerosol of organic electronic materials is shielded from the outer tube containing plasma and the organic electronics is focused at the outlet of the nozzle through the after-glow region of the atmospheric pressure plasma. Ensuring reproducibility of the method for printing organic electronic materials by removing the contaminants and residues in inner tube using reactive gas and generating a plasma discharge at a potential significantly higher than the operating potential for printing so that the plasma is generated in both the inner and outer tube for dielectric barrier discharge plasma jet based cleaning of the nozzle.

Abstract: A device and method for printing 3D articles including electronic and functional elements including 3D printer and a plasma jet printer based on a dielectric barrier atmospheric pressure plasma jet system in which both printing and in-situ treatment and post-deposition treatment can be carried out to tailor the materials characteristics. Plasma jet printer comprising of electrodes in the nozzle/print head for applying electric field and generating atmospheric plasma that could be used for non-gravity based highly directional printing in any direction. Integration of dielectric barrier plasma printer and plasma treatment jets with the 3D printer increases the capability of embedding high performance electronics in a 3D printed structure aiding in additive manufacturing of functional devices. Ability to use a range of materials for print head assembly including micro machined silicon increases the resolution of the plasma jet printer to sub-micron level.

Abstract: Systems and methods for allowing analog Ising machines to be able to run Integer Linear Programming (“ILP”) problems, i.e. a compilation method for setting the state of the physical memory units, flexible to be adapted to each specific device. The method describes how variables and numeric parameters which specify the problem can be hard-coded (embedded and physically represented) in the hardware circuitry of the device in a deterministic way, with a pre-determined bound on the number of required physical spins to be used in the Ising device.

Abstract: The present disclosure provides ex vivo-derived mineralized three-dimensional bone constructs. The bone constructs are obtained by culturing osteoblasts and osteoclast precursors under randomized gravity vector conditions. Preferably, the randomized gravity vector conditions are obtained using a low shear stress rotating bioreactor, such as a High Aspect Ratio Vessel (HARV) culture system. The bone constructs of the disclosure have utility in physiological studies of bone formation and bone function, in drug discovery, and in orthopedics.

Abstract: A process for producing isotopes by continuously flowing a liquid stream, carrying capsules of target nuclei (NP-237) in solution, through a nuclear reactor (a TRIGA style nuclear reactor). Upon removal from the core of the nuclear reactor and after allowing for the decay of Np-238 to Pu-238, the capsules are emptied and the mixture of elements and isotopes are chemically separated using solvent extraction or ion exchange.

Abstract: Systems and methods for providing generic post-generation annotation inference for verification of auto-generated code by automatically inferring safety annotations used to prove software safety. The inferred logical annotations are obtained by taking into account code patterns and safety requirements. The locations for inserting the annotations in the auto-generated code are obtained by using the code patterns to produce a flow graph of the result sensitive variables and the paths to all their corresponding definitions. The verification is customized to reduce unwarranted warnings by imposing no inherent restriction on the precision. A detailed report of verification of the auto-generated code is generated to permit independent verification and validation by a third party. The method operates independently from a model used to generate the code or internal templates of the code generator. The system may use untrusted components for inferring annotations and annotating the code.

Abstract: Centrifugal analyzer and method for staining biological or non-biological samples in microgravity, wherein the method utilizes an increase in weight of a fluid sample as a function of g-load, to overcome cohesive and frictional forces from preventing its movement in a preselected direction. Apparatus is characterized by plural specimen reservoirs and channels in a slide, each channel being of differing cross-section, wherein respective samples are selectively dispensed, from the reservoirs in response to an imposed g-factor, precedent to sample staining. Within the method, one thus employs microscope slides which define channels, each being of a differing cross-section dimension relative to others. In combination therewith, centrifugal slide mounting apparatus controllably imposes g-vectors of differing magnitudes within a defined structure of the centrifuge such as a chip array.

Three or more LEDs blue, aqua, green, yellow, orange, crimson, red and infrared provide a range of readings across the visible and infrared spectrum.
