Abstract: A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft. The compartment may be sized to receive the prosthetic heart valve. The inner shaft and the distal sheath may be movable relative to one another. A spine may extend along the outer shaft, the spine biasing the outer shaft so that the outer shaft tends to bend in a pre-determined direction.

Abstract: The techniques disclosed herein enhance the efficiency and functionality of directory systems. This is accomplished by augmenting a primary table with an extended table for storing properties of an associated entity (e.g., a user, a company). A table serves to organize directory data and comprises rows and columns. Each row of the primary table stores an entity with each column storing an associated property. In contrast, the primary table is configured with an extended table in which each row of the extended table stores a property for an associated entity while each column stores additional information for the property such as timestamps and metadata. Storing specific properties in the extended table eliminates empty spaces in the primary table thereby reducing the volume of stored data. Moreover, by including additional data for properties, the extended table enables property-specific features such as search, synchronization, extensibility, and lifecycle management.

Abstract: Described herein are battery packs and electric vehicles using these packs. In some examples, a battery pack comprises two portions/covers and a set of battery modules positioned within the enclosed cavity formed by these portions. A battery pack may comprise a set of pressure-relief valves positioned in and protruding through a wall of at least one portion. Each valve can be coaxial with a corresponding gap provided between two adjacent modules. The valve is configured to provide a fluid path (to the exterior of the battery pack) when the pressure inside the pack exceeds a set threshold. In some examples, the battery pack comprises an inlet tube fluidically coupled to the inlet port of each module and an outlet tube fluidically coupled to the outlet port of each module. A set of specially configured orifices or controllable valves is positioned on the fluid path through each module.

Abstract: A ladder rack system may have a slide with a support flange and a spanning flange. The system may also have a ladder support member adapted to selectively receive a portion of the support flange therein. The system may also have a pivot bracket pivotally connected to the ladder support member. The pivot bracket may be adapted to selectively move the ladder support member.

Abstract: A method, system, and computer program product are disclosed for implementing enhanced noise impact on function (NIOF) analysis of an IC design having nets in multiple different variable voltage domains next to each other and modeling all multiple worst-case victim-aggressor voltage configurations in a single run leveraging noise abstracts characterized at a single voltage corner. The NIOF analysis enables accurately identifying incorrect victim switching or functional fails, effectively and efficiently providing design verification and the ability to sign-off an IC design with a single run, and enable modifying an integrated circuit design to fix NIOF failures, and fabricating an integrated circuit.

Abstract: A junctional tourniquet apparatus and related methods of use. An exemplary tourniquet has an inverted cone shape, wherein a narrower end has a mushroom shaped base that is pressed against a compression target and a broader end has a plurality of pass-through slots for straps. Another exemplary tourniquet has a broad plate component and a handle component. The handle component has a mushroom shaped base on a first end and a handle on a second end.

Abstract: Disclosed is the invention to conduct immuno-adsorption of free 25(OH) vitamin D from blood or blood components, notably serum or plasma, after which the absorbed material is measured. A fluoro-alkyl surfactant is used to enhance the solubility of Vitamin D and allow the measurement of free Vitamin D2. The invention thus employs a binding protein to absorb the free 25(OH) vitamin D. Thereafter the binding protein comprising the 25-OH vitamin D is subjected to a competitive binding assay with a labeled vitamin D compound, preferably radiolabeled, fluorescent labeled, luminescent labeled, biotin labeled, gold labeled or enzyme labeled. Alternatively the immunocaptured 25-OH vitamin D can be quantitated by mass spectrometry.

Abstract: Provided herein is a method for detecting the presence of clade variants in the COVID-19 virus in a human sample and/or an environmental sample. Samples are processed to obtain total RNA. The RNA is used as a template in a combined reverse transcription and amplification reaction to obtain fluorescent COVID-19 virus amplicons. These amplicons are hybridized on a microarray with nucleic acid probes having sequences that discriminate among the various clade variants. The microarray is imaged to detect the clade variant. Also provided is a method of distinguishing each clade variant from others by generating an intensity distribution profile from the image, which is unique to each of the clade variants.

Abstract: A slurry containing CO2 in solution passes through a venturi at high velocity. As pressure drops within the venturi reactive gases are introduced. Cavitation is induced releasing energy helping mix the slurry with the additive gases and increase a chemical reaction rate and creating a more uniform distribution of ions allowing for better reaction rates. A precipitate is formed sequestering CO2.
