Abstract: The present disclosure provides methods and compositions for preparing nucleic acid molecules using a novel, single-tube workflow that allows users to carry out the isolation of nucleic acids from a sample and perform a nucleic acid assay using the isolated nucleic acids in a single tube or vessel. As such, the methods disclosed herein can be used with low quality and/or small quantity of nucleic acid samples. Further, the disclosed methods offer similar or improved concordance rates in addition to improved signal to noise ratio when compared to the existing methods used for genetic analysis. Thus, making the methods disclosed herein suitable for clinical applications such as infectious disease diagnosis, pre-implantation genetic testing, prenatal or cancer diagnosis.

Abstract: An annotation pipeline may be used to produce 2D and/or 3D ground truth data for deep neural networks, such as autonomous or semi-autonomous vehicle perception networks. Initially, sensor data may be captured with different types of sensors and synchronized to align frames of sensor data that represent a similar world state. The aligned frames may be sampled and packaged into a sequence of annotation scenes to be annotated. An annotation project may be decomposed into modular tasks and encoded into a labeling tool, which assigns tasks to labelers and arranges the order of inputs using a wizard that steps through the tasks. During the tasks, each type of sensor data in an annotation scene may be simultaneously presented, and information may be projected across sensor modalities to provide useful contextual information. After all annotation tasks have been completed, the resulting ground truth data may be exported in any suitable format.

Abstract: Surface micro-texturing has been proven an effective way to reduce friction and wear for tribological applications. There is provided a low cost hot sintering method to apply micro-texturing on an advanced bearing polymer material. First, one face of the mold was micro-textured using a micro-casting method. Second, the cured Aromatic Thermosetting coPolyester (ATSP) powder was filled in the mold. Next, the filled mold was placed in a hot press for a hot sintering process. Finally, the textured bulk ATSP was cooled. The micro-textured ATSP bulk material was machined and compared with plain untextured material. The micro-textured material could effectively reduce friction at speeds lower than 2.46 m/s: 14% reduction in average.

Abstract: A cable line label device includes a platform. The platform has a top end positioned opposite a bottom end. Additionally, the platform also includes a first side formed opposite a second side. The platform defines an arcuate curvature from the first side to the second side. The platform will form a flush surface with a cable when the cable line label device is placed on the cable. A first fastener is placed at a top end of the platform and a second fastener is placed at a bottom end of the platform. The first fastener and the second fastener are designed to secure the platform to the cable.

Abstract: Detecting different mutations in the same sample is essential, especially where the sample is limited in quantity and where high-throughput methods are desired for rapid detection of mutations. Methods routinely used in the art require separate assays for detecting different mutations or mutation types (e.g. single nucleotide polymorphisms (SNPs) or copy number variations (CNVs)) in a sample. The present disclosure provides methods for detecting different mutations, such as SNPs and CNVs in the same sample.

Abstract: This patent describes a new, simple, and low-cost method to produce aromatic thermosetting copolyester (ATSP) based polymer matrix composites. For this method, the ATSP based composites are directly produced from the blended mixtures of the ATSP oligomer powders with the composite fillers through a high temperature and high pressure curing process. In addition, the fully cured ATSP composite laminates can be bonded together to form thicker multi-material composites. The characterization showed that these ATSP based composites are fully condensed, they have excellent tribological performance (low friction and low wear rate), and they have excellent thermal stability, indicating utility in high performance bearing applications, structural materials, and as an ablative composite material.

Abstract: A novel Aromatic Thermosetting Copolyester (ATSP) fully dense sheets can be processed by recycling the foam structure with unique combination of properties including mechanical strength and high temperature performance (compared to PEEK) to help improve part functionality, gain long-term reliability and cost savings. ATSP machinable plates can be used in valves, fittings, bearing, bushing, seals, aerospace parts and pump components.

Abstract: A materials trouble shooter is provided for use with 3D models in computer graphics. An error texture is displayed that is distinguishable from textures without errors. If a texture is missing or is applied incorrectly to the 3D model, an error texture is displayed using an error shader instead of a regular shader for the texture for which an error in loading or application has been detected.

Abstract: A novel Aromatic Thermosetting Copolyester (ATSP) can be processed into highly effective wear resistant coatings by blending with polytetrafluorethylene (PTFE) and other additives. Surface treatments/coatings are key to improving wear performance and durability in a wide array of applications. The problems associated with use of liquid lubricants, hard/soft coatings are well known but only modest progress has been achieved due to lack of research on new material systems. These coatings were fabricated and tested as highly effective wear resistant coatings by blending ATSP with PTFE and other tribologically beneficial additives. The main advantages of these polymeric-based coatings are their relatively low cost and simple substrate surface conditioning (i.e., no need for expensive surface preparation before coating).
