Abstract

An interfacial plasmonic heating intensified IP reaction (IPH-IP) is used to fabricate highly permeable and selective polyamide RO membranes. Silver nanoparticles (AgNPs) are introduced to the IP reaction interface to serve as nano-heat generators under light illumination. The coupling of generated nano-heat rapidly promotes the interfacial temperature, thereby boosting the formation of extensively “nano-foamed” polyamide with prominent nanovoids and high crosslinking degree. These features enable the resulting RO membrane to achieve a superior combination of water permeance (3.4 L m−2 h−1 bar−1) and NaCl rejection (99.7%). This outstanding separation performance further enables the membrane to efficiently remove a wide spectrum of toxic contaminants frequently found in different water sources, revealing huge potential for various water treatment applications. In addition, the resulting RO membrane demonstrates efficient desalination of real seawater, producing clean water with high quality that far exceeds those of benchmarking commercial membranes.

Abstract

A two-dimensional spectrum recording apparatus has a source of collimated laser light impinging on a sample on a plate. The light passing through the sample forms an object wave and the light not passing through the sample forming a reference wave, which interfere with each other to form a holographic image at the plate. A beam splitter receives the collimated laser light from the sample and forms separate first and second light beams. A linear polarizer receives the first beam and passes it to a polarization camera having a Full Stokes mask. The camera records the light that passes through the Stokes mask. A slit aperture receives the second beam and transforms it into a slit of light that is applied to a diffraction grating. A diode array receives the second beam from the diffraction grating and forms a light spectrum that is recorded.

Abstract

The T-cell receptor (TCR) plays a crucial role in the adaptive immune response by recognizing specific antigens. In the context of cancer immunotherapy, TCR sequences can be engineered to target specific tumor antigens. In this study, hepatocellular carcinoma (HCC) was modeled in mice by combining genetic alterations recurrently observed in the human disease, and identified HCC-specific TCRs using single-cell TCR-seq. TCR convergence was observed across HCC-bearing mice, indicating that TCRs specific for HCC antigens elicit the expansion of CD4+ T cells. To further elucidate the function of this HCC-specific TCR, TCR-expressing vectors were designed and built, which can be used for various in vitro and in vivo applications, including identifying the specific peptide sequence that the TCR recognizes, manufacturing TCR-engineered T cells, studying T cell function, and screening potential immunotherapies. The findings have important implications for the development of T cell-based cancer immunotherapies.

Abstract

Provided is a reliable and convenient approach to achieve precise control of gene expression in the liver in vivo. The methods generally combine a doxycycline-inducible gene expression system with a Sleeping Beauty transposon vector and hydrodynamic injection, enabling efficient integration of a controllable gene expression system into the genome of hepatocytes. The doxycycline-inducible system generally allows for precise and reversible control of gene expression. In some forms, a combination of gene alterations and overexpression of Myc leads to the development of HCC in animals. The method can also use a vector that allows for the inducible expression of a tumor antigen. The method can also induce tumor antigen-specific T-cell immune responses, providing a potent tool for the development of targeted therapies for HCC.

While maintaining a sufficient workspace (± 35°), the positioner remains lightweight (203 g) and compact ( Ø 81 mm × 97 mm height), enabling skull-mounted usage within most standard imaging head coils. The five-bar linkage architecture allows the reservation of exposure space around the incision port (burr hole on the skull) for operation/observation. The robot system operates in two stages: i) manual coarse adjustment within a large workspace performed interactively by the surgeon, followed by ii) automated fine adjustment within a localized motion range performed by soft fluid-driven actuators.

Abstract

Methods for detecting adaptive immune responses to pathogens or self-antigens by antibody or B cell or T cell binding to antigenic epitopes have been established. The methods inform functional and structural interactions between immune receptors and antigens, identify potential therapeutic targets and guide vaccine development. The methods employ high throughput modified mRNA-display or variations of droplet display to determine single epitope-specific antibody and B- and T- cell receptor sequences at the genomic scale at single epitope and single amino acid resolution. In some forms, the methods collect and integrate the data to provide a database of an adaptive immunity profile for a human or animal subject. In some forms, the methods identify and record changes in an immunity profile over different time points to reflect immunological responses in a subject. The methods provide high resolution immunity profiles of immune responses at the genomic level for diagnostic, prophylactic, and therapeutic applications.

Abstract

A human balance sensor for assessing the risk of the user falling includes a transparent glass plate, a latex sheet located on the top surface of the glass plate, a light source located so as to inject light into edge of the glass plate and a high resolution camera located below the glass plate so as to capture light diffused from the glass plate when pressure is applied thereto by the user's foot. Based on the principle of Frustrated Total Internal Reflection (FTIR), when user stands with his feet on the glass plate a condition of total internal reflection is eliminated at pressure locations due to the pressure from the feet, and diffused light passes from the bottom surface of the glass plate and forms a haptic image of the contact area of the feet which can be analyzed over time to determine the user's ability to balance, and hence their risk of a fall.

Abstract

A computer-implemented geometric processing method generates the design for a model of a dental prosthesis beginning with obtaining a blended prosthesis dataset for dental prostheses including natural tooth data and prosthesis tooth data designed by a technician. This dataset is preprocessed by generating a depth map with preprocessing so that the data is more suitable for deep learning (DL) so as to ensure generation of a smooth surface. An artificial intelligence neural network generation model with tooth feature loss is trained on the preprocessed dataset and is used to form a model of the prosthesis. Then the dental information associated with the dental model of dentition is used to generate a 3D dental prosthesis surface with a post-processing method to meet the requirement of the dental prosthesis. Finally, the rest of the dental prosthesis is completed to meet full function.

Abstract

A method of improving an information transmission rate involves reducing atmospheric distortions by emitting at the same or nearly the same wavelength a reference source for adaptive optic correction and a signal source for optical communication. The reference source is brighter than the signal source and the (pulsed or continuous) reference source is emitted earlier than the (pulsed or continuous) signal source. By adjustment of the time delay between the reference source and the signal source and/or the delay time in adaptive optics control and/or apparent angular speed of the sources relative to the detecting module and/or the physical separation between the reference source and the signal source, the optical paths of a reference source beam and a signal source beam have about same wavefront distortion. The reference source beam and the signal source beam are detected in a side by side manner by detectors physically located next to each other. Adaptive optics are used for wave distortion correction on the reference source to simultaneously correct distortion of the signal source.

Abstract

The subject invention pertains to multifunctional tendon-mimetic hydrogels constructed from anisotropic assembly of aramid nanofiber composites. The stiff nanofibers and soft polyvinyl alcohol in these anisotropic composite hydrogels (ACHs) mimic the structural interplay between aligned collagen fibers and proteoglycans in tendons. The ACHs uniquely exhibit a high modulus of ˜1.1 GPa, strength of ˜72 MPa, fracture toughness of 7333 J/m2, and many additional characteristics matching those of natural tendons. The surfaces of ACHs can be functionalized with bioactive molecules to present biophysical cues for the modulation of morphology, phenotypes, and other behaviors of attached cells. Moreover, soft bioelectronic components can be integrated on ACHs, enabling in-situ stimulation and sensing of various physiological parameters. The outstanding mechanics and functionality of these tendon-mimetics can be advantageously applied to advanced tissue engineering, implantable prosthetics, human-machine interactions, and other technologies.

Abstract

A system for inspecting surfaces that includes a mobile base, sensors for base navigation, sensors for surface inspection, a communication system and a host computer that executes modules for base motion planning and navigation, location, point cloud acquisition and processing, surface modelling and analysis, multi module coordination and user interfaces. The inspection procedure has the robot move in a zigzag pattern trajectory over the surface. For every fixed distance, a 3D point cloud of the surface is generated and the location of the point cloud with respect to the world coordinate system is recorded. The location of the point cloud is based on SLAM for spatial mapping. At the same time, a high-resolution photo of the corresponding area on the surface is recorded by the camera. Both the point cloud and the photo are transmitted to the host computer for processing and analysis. This information is used in a new 3D detection and image processing algorithm to find flaws in the surface like bumps or depressions. If irregular flaws are detected, the robot marks such a problematic location.

Abstract

A system for the rectification of batch-induced distortions and the extraction of phenotypic attributes from biological images is presented. This system encompasses a deep-learning generative adversarial network model, expertly tailored to converse with and modify the contrast of input images, resulting in the creation of output images. A discriminator, operating as a feedback mechanism, discriminates the output image against the input image, ensuring precise image contrast conversion. Integral to this system is a morphology distillator, having a dual classifier framework comprising a batch classifier and a cell type/state classifier. This distillator adeptly identifies phenotypic characteristics and batch-related disparities, subsequently eradicating these batch variations from the output image. The resultant augmentation enriches the cellular information within the image.
