  • Patent number: 12370254
    Abstract: We have recently developed a novel DC-targeting vaccine platform using Ebola glycoprotein (EboGP) DC-targeting domain-based fusion protein technology. Here, we will use this technology to generate universal vaccines against Influenza A by fusing a DC-targeting/activation domain (EboGPAM), derived from EboGP to I) a tetrameric conserved extracellular domain of M2 (M2e) of Influenza A strains from human, birds, and swine; 2) the conserved stalk regions (HAcs) of HA and an M2 polypeptide from H5N1 strain; and 3) the HA head regions polypeptides (HAH5-1-3) derived from H5N1, H1 N1 and H3N2 strains.

  • Patent number: 12186753
    Abstract: Described herein is a method for mixing unequal amounts of two reagents to produce a detectable reaction in a microfluidic chip. In one example, there is a fluorescent microfluidic urinary albumin chip (UAL-Chip) that exploits the nonimmunological fluorescent assay. In this chip, we constructed a passive and continuous mixing module, in which the loading process requires only an inexpensive dropper, and the signal is stable over time, as discussed below. We applied a pressure-balancing strategy based on the immiscible oil coverage which highly improves the precision in controlling the mixing ratio of sample and dye. The UAL-Chip has achieved an estimated limit of detection (LOD) of 8.4 ?g/ml using albumin standards, which is below the 30 ?g albumin per ml urine level considered to be indicative of kidney damage.

  • Patent number: 11971440
    Abstract: A method for identifying one or more faulted conductors in a power transmission system having at least two power-transmitting conductors and a method for determining fault location each include steps of monitoring current signals which are representative of currents in the conductors at a generally common location within the power transmission system; filtering the current signals; determining a maximum rate of change of each filtered current signal within a predetermined time interval after the fault event has commenced; and calculating a ratio of a pair of the maximum rates of change of the filtered current signals. For fault classification, the ratio is compared against a discrimination factor to identify the one or more faulted conductors. For fault location, the calculated ratio is compared against the calibration data to determine the distance from the connection terminal of the faulted conductor to the fault location.

  • Patent number: 11946878
    Abstract: A device for unidirectional propagation of microwaves comprises a resonant microwave structure arranged to transmit microwaves between two ports and a magnetic source arranged to provide a generally static magnetic field and to have a resonant frequency distinct from that of the microwave structure, which is disposed adjacent the microwave structure so as to be located in presence of electromagnetic fields emanating from the transmitted microwaves such that the magnetic field interacts with the electromagnetic fields of the microwaves so as to form a set of hybridized resonant frequencies at which zero intrinsic damping exists, one of the set of hybridized resonant frequencies being a real eigenvalue providing the unidirectional propagation from one of the first and second ports to the other. A related method comprises arranging the magnetic source at a prescribed position where the real eigenvalue matches the frequency of an input signal applied at a selected port.

  • Patent number: 11746030
    Abstract: Aerobic granular sludge (AGS) is an energy efficient and compact biological wastewater treatment process. There is only one commercially available AGS technology which utilizes sequencing batch reactors (SBR). Many existing wastewater treatment facilities consist of long, continuous flow reactors that would not be readily suitable for retrofit to SBR. Therefore, a continuous flow process is preferred for municipalities that cannot economically invest in the only commercially available SBR technology (i.e., Nere-da®). Lab- and pilot-scale experimentation has demonstrated that stable granulation can be achieved in a continuous flow configuration GT suitable for retrofit into existing infrastructure. An anoxic/anaerobic/aerobic configuration can be designed and stably operated for conversion of flocculent biomass to AGS Preliminary pilot-scale results on primary effluent from a municipal wastewater treatment facility indicated that granules of 0.2-0.

  • Patent number: 11692972
    Abstract: An ultrasonic sensing technique and a signal interpretation method based on a spectral element multiphase poromechanical approach overcomes critical gaps in permafrost, frozen soil, and saturated soil characterization. Ultrasonic sensing produces high-quality response signals that are sensitive to the soil properties. A transfer function denoting a ratio of induced displacement and applied force in the frequency domain, is independent of the distribution of the stress force applied by the transducer to the sample, and allows interpretation of the measured electrical signal using a theoretical transfer function relation to efficiently determine the most probable properties from response signals using an inverse spectral element multiphase poromechanical approach. This ultrasonic sensing technique enables rapid characterization of soil samples in terms of both physical and mechanical properties.

  • Patent number: 11513056
    Abstract: A dual light source lens-free dielectrophoresis (DEP) flow cytometer for massively parallel single cell analysis. Each cells dielectric is inferred from measuring their altitude and subsequently velocity change due to DEP actuation in a microfluidic channel. Dual LED sources facilitate velocity measurement by producing two shadows for each cell passing through the channel. These shadows are detected using a linear optical array detector. Massively parallel analysis is possible as each pixel of the detector can independently analyze the passing cells. The DEP cytometer is composed of simple modular components and has the potential to be scaled to achieve a significantly high throughput label-free single-cell analyzer.

  • Patent number: 11513052
    Abstract: Determination of transport phenomena properties in porous media is one major objective of core analysis studies in petrophysics, reservoir engineering, and groundwater hydrology. Porosity measurement may be considered as a key factor to identify the hydraulic performance of a low permeable porous medium (e.g. rock or concrete). Additionally, the rate of absorption under pressure depends on the permeability, which is related to the connectivity between the existing pores within the porous structure. An alternative Gas Expansion Induced Water Intrusion Porosimetry (GEIWIP) method and apparatus is useful to measure the total porosity and pore size distribution, using a gas/water intrusion apparatus for water tight materials.
