  • Patent number: 10391309
    Abstract: The present disclosure refers to systems for electrical neurostimulation of a spinal cord of a subject in need of nervous system function support. In one example, a system comprises a signal processing device configured to receive signals from the subject and operate signal-processing algorithms to elaborate stimulation parameter settings; one or more multi-electrode arrays suitable to cover a portion of the spinal cord of the subject; and an Implantable Pulse Generator (IPG) configured to receive the stimulation parameter settings from the signal processing device and simultaneously deliver independent current or voltage pulses to the one or more multiple electrode arrays, wherein the independent current or voltage pulses provide multipolar spatiotemporal stimulation of spinal circuits and/or dorsal roots. Such system advantageously enables effective control of nervous system functions in the subject by stimulating the spinal cord, such as the dorsal roots of the spinal cord, with spatiotemporal selectivity.

  • Patent number: 10392437
    Abstract: Peptides that specifically bind erythrocytes are described. These are provided as peptidic ligands having sequences that specifically bind, or as antibodies or fragments thereof that provide specific binding, to erythrocytes. The peptides may be prepared as molecular fusions with therapeutic agents, tolerizing antigens, or targeting peptides. Immunotolerance may be created by use of the fusions and choice of an antigen on a substance for which tolerance is desired. Fusions with targeting peptides direct the fusions to the target, for instance a tumor, where the erythrocyte-binding ligands reduce or entirely eliminate blood flow to the tumor by recruiting erythrocytes to the target.

  • Patent number: 10380309
    Abstract: We present a Boolean logic optimization framework based on Majority-Inverter Graph (MIG). An MIG is a directed acyclic graph consisting of three-input majority nodes and regular/complemented edges. Current MIG optimization is supported by a consistent algebraic framework. However, when algebraic methods cannot improve a result quality, stronger Boolean methods are needed to attain further optimization. For this purpose, we propose MIG Boolean methods exploiting the error masking property of majority operators. Our MIG Boolean methods insert logic errors that strongly simplify an MIG while being successively masked by the voting nature of majority nodes. Thanks to the data-structure/methodology fitness, our MIG Boolean methods run in principle as fast as algebraic counterparts. Experiments show that our Boolean methodology combined with state-of-art MIG algebraic techniques enable superior optimization quality.
