Abstract: The neuromodulation system includes a sensor, a recording amplifier, a processor, and a stimulator. The neuromodulation system is configured to provide stimulation and control of an intended target. The processor utilizes a closed-loop feedback system which is configured to actively sense target brain states and apply corrective stimulation or feedback as dictated by its effectors. The processor implements reinforcement learning which creates real-time statistical models of current and recent past neural states which actively and automatically learns stimulation paradigms which create paths from pathological to nominal brain states.

Abstract: The invention generally relates to systems and methods for performing multiple precursor, neutral loss and product ion scans in a single ion trap. In certain aspects, the invention provides systems including a mass spectrometer having a single ion trap, and a central processing unit (CPU), and storage coupled to the CPU for storing instructions that when executed by the CPU cause the system to apply at least one of the following ion scans to a single ion population in the single ion trap: multiple precursor ion scans, a plurality of segmented neutral loss scans, or multiple simultaneous neutral loss scans.
Abstract: Systems and methods for sensing vibrational absorption induced photothermal effect via a visible light source. A Mid-infrared photothermal probe (MI-PTP, or MIP) approach achieves 10 mM detection sensitivity and sub-micron lateral spatial resolution. Such performance exceeds the diffraction limit of infrared microscopy and allows label-free three-dimensional chemical imaging of live cells and organisms. Distributions of endogenous lipid and exogenous drug inside single cells can be visualized. MIP imaging technology may enable applications from monitoring metabolic activities to high-resolution mapping of drug molecules in living systems, which are beyond the reach of current infrared microscopy.
Abstract: A method of providing super-resolved images of a photon emitting particle is disclosed, which includes providing a machine-learning (ML) platform, wherein the ML platform is configured to receive pixel-based sparse autocorrelation data and generate a predicted super-resolved image of a photon emitting particle, receiving photons from the photon emitting particle by two or more photon detectors, each generating an electrical pulse associated with receiving an incident photon thereon, generating sparse autocorrelation data from the two or more photon detectors for each pixel within an image area, and inputting the pixel-based sparse autocorrelation data to the ML platform, thereby generating a predicted super-resolved image of the imaging area, wherein the resolution of the super-resolved image is improved by ?n as compared to a classical optical microscope limited by Abbe diffraction limit.

The metal matrix composite contains TiB2 particles, Al3Ti particles, and particles of an intermetallic compound of aluminum and at least one rare earth element dispersed in an aluminum matrix. Methods include casting a first melt to produce an ingot, remelting the ingot to form a second melt, forming a powder from the second melt using an atomization process, and fabricating a component utilizing the powder in an additive manufacturing process. The ingot and the powder include an aluminum matrix that contains dispersions of TiB2 particles and Al3Ti particles.
Abstract: This invention discloses a method for controlling nanoscopic wetting near or at a molecular scale for synthetic material applications. In particular this invention relates to a method for preparing a monolayer or thin film with a patterned nanoscopic wetting surface using a ‘sitting’ phase of polymerizable amphiphile, wherein hydrophobic alkyl chains of the amphiphile extend along the supporting surface and the amphiphile molecules align side-to-side, effectively forming a repeating cross-section of bilayer with alternating hydrophilic and hydrophobic stripes of a ˜6 nm pitch tunable based on the chain length of the amphiphile. Products prepared according to the methods disclosed herein are within the scope of this invention. In some embodiments, monolayers or thin films so prepared are transferable.
