  • Patent number: 12244226
    Abstract: Topologies and configurations of step-down power supplies including unidirectional balancing cells are described. In one example, a step-down power supply includes an input and an output, a string of series-connected capacitors, and a plurality of unidirectional balancing cells coupled to the capacitors in the string of series-connected capacitors. A first balancing can be configured to transfer power, unilaterally, in a first direction among at least two capacitors in the string of series-connected capacitors, and a second balancing cell can be configured to transfer power, unilaterally, in a second direction among at least two capacitors in the string of series-connected capacitors, where the first direction is different than the second direction. The power supply can also include a gate controller for a balancing cell. The gate controller generates switching control signals at a first switching frequency that is decoupled from a resonant frequency of a balancing branch in the balancing cell.

  • Patent number: 12235268
    Abstract: Compositions and methods for detection of anti-citrullinated protein antibodies (ACPAs) in rheumatoid arthritis (RA) patients. Patient samples known or suspected of containing ACPAs were probed against citrullinated proteins, and antibody responses to 190 citrullinated proteins in 20 RA patients were investigated. Unique antibody reactivity patterns in both clinical anti-cyclic citrullinated peptide assay positive (CCP+) and negative (CCP?) RA patients were observed. At individual antigen levels, six novel antibody/antigen complexes were discovered and validated against specific citrullinated antigens (Myelin Basic Protein (MBP), osteopontin (SPP1), flap endonuclease (FENI), insulin like growth factor binding protein 6 (IGFBP6), insulin like growth factor I (IGF1) and stanniocalcin-2 (STC2)) in RA patients. Identification of immune-dominant epitope(s) for citrullinated MBP was also performed. The identified biomarkers have high specificity, especially MBP.

  • Patent number: 12221654
    Abstract: The gene responsible for encoding SERT has a functional polymorphism at the 5?-regulatory promoter region, which results in two forms, long (L) and short (S). The LL-genotype is hypothesized to play a key role in the early onset of alcohol use. The present invention discloses the differences in treatment and diagnosis based on the L or short genotypes as well as on a single nucleotide polymorphism of the SERT gene, the 3? UTR SNP rs1042173. The present invention demonstrates the efficacy of using the drug ondansetron and similar drugs for treatment based on variations in the polymorphisms of the SERT gene as well as methods for diagnosing susceptibility to abuse of alcohol and other addiction-related diseases and disorders.

  • Patent number: 12220860
    Abstract: Photocurable colloid binders are provided that overcome deficiencies associated with 3D printing of high molecular weight polymers via VAT photopolymerization. Methods of additive manufacturing are also provided using the binders. The approaches described herein effectively decouple the viscosity-molecular weight relationship by synthesizing and processing photo-reactive aqueous colloids that are sequestered within a photocrosslinkable scaffold. Sequestering polymers within discrete internal phases prevents inter-particle entanglement of the polymer chains, thus ensuring low viscosity. VP of polymer colloids results in a solid green body embedded with high molecular weight polymer particles. A post-processing heated drying step allows the polymers to coalesce and further entangle, forming a semi-interpenetrating network with mechanical performance of the high molecular weight material. The resins can further include inorganic particles such as silica and other ceramics, metal particles, and the like.
