摘要： Collapsible containers are an attractive alternative to surface-tension propellant management devices (PMDs) for handling cryogenic liquids, as the collapsible container comparatively may 1) allow higher expulsion flow rates than vanes and sponges, 2) significantly reduce operational complexity, and 3) thermally insulate the propellant from environmental heat leaks. Furthermore, while historical cryogenic collapsible containers suffered from the low ductility of polymer films at cryogenic temperatures, the technology disclosed herein shows that the incorporation of folded patterns into the collapsible container substantially increases the reusability of the cryogenic PMD.

摘要： Disclosed is a novel room-temperature curable bio-based epoxy vitrimer with a simple design of the chemical structure. A hempseed oil-derived glycidyl ester type epoxy (HOEP) was synthesized and then blended with a bisphenol A epoxy (DER331) to manipulate the properties of the resulting vitrimer s. An aliphatic amine hardener, diethylenetriamine (DETA), was selected as hardener to realize the room temperature curing in presence of triethanolamine (TEOA) as the catalyst. Unlike the traditional glycidyl ether epoxy-amine the thermosets which are based on stable C-N and ether linkages, the epoxy vitrimer herein includes ester bonds with HOEP and hydroxyls formed from the reaction of amine and epoxy in its cross-linked network. Dynamic transesterification (DTER) between the ester bonds and hydroxyls take place at elevated temperatures, imparting the vitrimer significant stress relaxation behavior and repairability. This provided a viable method to produce room temperature curable epoxy vitrimer s.

摘要： The embodiments of the present invention are directed to a novel wireless powered method, apparatus and tracking system without a wired interface to a moving catheter. The implant in the patient's body on the moving catheter is energized by an external ultrasound transmitter using acoustic pressure waves. As a general mode of operation, ultrasonic waves from outside of a patient's body are received by an array of transducer elements configured about the catheter disposed in a patient's body, wherein the array of transducer elements transforms a frequency into a resultant stored energy. The resultant stored energy powers one or more transceivers via a power management arrangement and enables RF frequencies in a desired band to be output and received by external sensors. Coupled with ultrasound backscattering capabilities, the catheter provides a dual mode for accurate triangulated locations of the distal end of a moving catheter.

摘要： Individualized methods for the prevention and/or treatment of kidney disorders in cats are disclosed. The methods include identifying whether or not a cat is predisposed to developing kidney disorders by determining the total number of copies of Exon 3 in the feline apoptosis inhibitor of macrophages (fAIM) genes of the cat. Cats with at least 3 copies of Exon 3 are considered to be predisposed to kidney disorders to include tubulointerstitial fibrosis and/or Chronic Kidney Disease (CKD) and are provided with individualized kidney sparing therapies. Also disclosed is an in vitro amplification kit for determining the number of copies of Exon 3 in the feline apoptosis inhibitor of macrophages (fAIM) genes in a nucleic acid sample of interest.

摘要： A query suggestion to expand an initial query is calculated whereby the cost of the expanded initial query is bounded in both time and quality. The user validates a subset of the top-n answers Q (G) to a query Q and provides adjusted configuration parameters. The top-n diversified δ–expansion terms Q'are calculated from the validated subset of answers Q (G) to the query Q and are provided to an interactive user interface for selection. Answers Q' (G) for the top-n diversified δ –expansion terms Q'are cost bounded by cost threshold δ and exploration range r specified by the user. The user selects a new term of terms Q'and an incremental query evaluation of the new term is invoked to compute expanded query answers Q' (G) by incrementally updating the validated subset of answers Q (G), without re-evaluating an expanded query Q'including the new term from scratch.

摘要： The embodiments herein provide for an oxygen/air cathode that includes metal-organic frameworks and/or hybrids of metal-organic frameworks and carbon networks. The metal- organic-framework-based Li-O 2 cells are operated in humid O 2 where water plays a critical role in improving battery performance. Such embodiments not only improve battery performance but also reduces the cost by cycling the Li-O 2 batteries in humid oxygen with MOF@CNT hybrid catalysts.

摘要： This disclosure describes systems and methods for using pyrolysis tail gas as the source for additional hydrogen to be used in the pyrolysis reaction. Tail gas is separated from the pyrolysis products and a portion of the tail gas is converted into formic acid (HCOOH). The formic acid is then injected into the pyrolysis reactor where it becomes the donor of two monohydrogen atoms and is ultimately converted into CO2 under reaction conditions. In this fashion, a closed loop pyrolysis hydrogen donor system may be created utilizing a generally non-toxic intermediary derived from the pyrolysis reaction products. This disclosure also describes using a ruthenium catalyst supported on particles of activated carbon to improve the yield of pyrolysis reactions.
