  • Patent number: 11820878
    Abstract: Ultra-stable aqueous foam comprises hydrophobic silica particles residing within bubbles in an aqueous solution of a hydrophilic polymer, a protein, or aqueous dispersible colloidal particles. The combination of the hydrophobic and hydrophilic components stabilizes the foam interfaces to result in long term stability of the foam. The foams can be crosslinked to stable monolithic foams and used for structural foams, coatings, and thermal insulating for construction.

  • Publication number: 20230342885
    Abstract: Denoising of magnetic resonance (MR) images can be achieved using a deep neural network and an image acquisition process that uses multi-NEX (Number of Excitations) or multi-NSA (Number of Signal Averages or Acquisitions) to produce two or more complex-valued images of a region of interest. The set of images resulting from the image acquisition process can be input to a deep neural network that has been trained to produce a denoised MR image from a set of multi-NEX or multi-NSA images. The deep neural network can be implemented using a two-dimensional or three-dimensional convolutional neural network to match the dimensionality of the input images. Training of the denoising neural network can use real MR images.

  • Patent number: 11788562
    Abstract: The subject invention pertains to a pneumatic, hydraulic, or otherwise inflatable or pressurized artificial muscle. Also provided are methods for making, controlling, and using such a muscle useful for prostheses, movement aids, or wearable robots to assist the movement of impaired subjects or to improve the function of healthy subjects. Muscles can be made by densely winding tension wires around pressurized expandable tubes having one or more specific geometric shapes removed from the tube cross section. The curve of output characteristics such as output force vs. contraction ratio can be adjustable by changing parameters of the sectional view of the tube. The appropriate shape of tube and related output characteristics can be selected according to application area or body part to be assisted to achieve the most flexible and optimal design for one or more muscle groups.

  • Patent number: 11725245
    Abstract: Methods, systems, and apparatus are provided for determining whether a nucleic acid sequence imbalance exists within a biological sample. One or more cutoff values for determining an imbalance of, for example, the ratio of the two sequences (or sets of sequences) are chosen. The cutoff value may be determined based at least in part on the percentage of fetal DNA in a sample, such as maternal plasma, containing a background of maternal nucleic acid sequences. The percentage of fetal DNA can be calculated from the same or different data used to determine the cutoff value, and can use a locus where the mother is homozygous and the fetus is heterozygous. The cutoff value may be determined using many different types of methods, such as sequential probability ratio testing (SPRT).

  • Patent number: 11718850
    Abstract: Particular forward and reverse primers may be used to link distant regions of the same large DNA molecule into a smaller DNA molecule. A reverse primer R1 can have a first portion complementary to an ending sequence of region A and can have a second portion having an overlapping sequence. A forward primer F2 can have a first portion complementary to a starting sequence of region B, where the forward primer includes a complementary overlapping sequence (e.g., the same first portion or a second portion) that is complementary to the overlapping sequence. The first portion of F2 may be the entire primer. The smaller DNA molecules can be used to determine haplotypes of regions. Kits including the particular forward and reverse primers are also described.

  • Publication number: 20230236273
    Abstract: Systems and methods for fast and robust quantification of magnetization transfer (MT) use off-resonance spin-lock MRI with as few as two or three image acquisitions. Each image acquisition can be performed using an off-resonance spin-lock pulse having a different RF amplitude and frequency offset. A parameter representing the difference of the relaxation rate in the rotating frame between the acquisitions can be computed. This parameter can be used to compute other parameters of magnetization transfer.
