  • Publication number: 20200172789
    Abstract: A well fluid composition includes powdered polylactic acid having a selected melting temperature below a lowest expected temperature of a subsurface formation into which the composition is to be introduced. The composition includes powdered polymer suspension aide and/or viscosifier in an amount which when hydrated enables suspension of the powdered polylactic acid in liquid for at least 2 hours and up to 24 hours. The powdered polylactic acid and the powdered polymer solids suspension aide and/or viscosifier are mixed with a liquid capable of hydrating the powdered polymer solids suspension aide and/or viscosifier.

  • Patent number: 10672092
    Abstract: A system for normalizing aggregated electronic data may include at least one processor and a memory. The processor may access data scraped from a plurality of local databases, each storing localized terms for temporal local milestones; for example, a first localized term for a first temporal milestone in a first locale may differ from a second localized term for a similar second temporal milestone in a second locale. The processor may store the temporal local milestones in a central database, determine a mapping of each of the localized terms for each temporal local milestone to a normalized term for each milestone, and identify, in a displayed timeline associated with the first locale, each associated temporal local milestone using the normalized term for each milestone. The processor may further identify, in a displayed timeline associated with the second locale, each associated temporal local milestone using the normalized term for each milestone.

  • Publication number: 20200104407
    Abstract: The disclosed embodiments provide a system that performs A/B testing using ego network clusters. During operation, the system obtains a graph that includes a set of nodes representing users in an online network and a set of edges representing relationships or interactions between pairs of the nodes. Next, the system selects egos containing a subset of the users that are representative of a distribution of an attribute across the users. The system then generates clusters of users, such that each cluster contains an ego and alters selected from the ego's connections in the graph. The system further divides the clusters between a treatment group and a control group, exposes alters in the treatment group to a treatment variant of an A/B test, and exposes alters in the control group to a control variant of the A/B test. Finally, the system outputs a result of the A/B test.

  • Publication number: 20190323042
    Abstract: The invention provides for methods by which the economics of the gas fermentation process are improved. The invention provides for the integration of a fermentation process, with an industrial process and an electrolyzer process. The invention provides for the intermittent supply of electrolyzer feedstock from the electrolyzer process to the bioreactor for fermentation. The electrolyzer feedstock may displace at least a portion of the C1 feedstock from the industrial process. The electrolyzer feedstock may supplement the C1 feedstock from the industrial process. Whether or not the electrolyzer feedstock supplements or displaces the C1 feedstock with electrolyzer feedstock may be based upon a function of the cost per unit of the C1 feedstock, the cost per unit of the electrolyzer feedstock, and the value per unit of the fermentation product.

  • Patent number: 10441445
    Abstract: Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium and one or more platinum group metals, refractory metals, precious metals, or combinations thereof. Platinum group metals include platinum, palladium, ruthenium, rhodium, osmium, and iridium. Refractory metals include zirconium, niobium, rhodium, molybdenum, hafnium, tantalum, tungsten, rhenium, and precious metals include silver and gold. In one embodiment, the one or more included platinum group or refractory metals substitute at least partially for nickel, such that the alloy exhibits reduced nickel content, or is substantially nickel free. The stents exhibit improved radiopacity as compared to similar alloys including greater amounts of nickel.

  • Publication number: 20190227122
    Abstract: A built-in self-test (BIST) method includes providing expanded test patterns to a logic circuit under test, generating a first signature based on a response of the logic circuit to the expanded test patterns, generating a second signature based on the first signature, wherein the second signature is a compressed version of the first signature, selecting one of the first signature or the second signature in response to a control signal, comparing the selected one of the first signature or the second signature to an expected signature, and, based on the comparison of the selected one of the first signature or the second signature to the expected signature, determining that the logic circuit passes or fails BIST.

  • Patent number: 10323010
    Abstract: The present invention pertains generally to the field of chemical synthesis, and more particularly to methods of chemical synthesis which include the step of preparing a substituted 10H-phenothiazine-3,7-diamine compound of Formula (1) by a step of selective alkylation by reductive amination, in which the corresponding unsubstituted diamine of Formula (4) is reacted with aldehyde/ketone, under reductive amination conditions. The present invention also relates to such methods which incorporate additional subsequent and/or preceding steps, for example, to prepare compounds of Formulae (2) and (3) from compounds of Formula (1), and to prepare compounds of Formula (4) from, for example, compounds of Formulae (5), (6), (7), (8), and (9). Compounds of Formula (1), Formula (2), and Formula (3) are useful, for example, in the treatment of diseases of protein aggregation, such as Alzheimer's disease.

  • Patent number: 10247780
    Abstract: The PRPG provides the test stimulus to the circuit, but it can only generate a finite number of care-bits from any given input seed which limits the maximum coverage that can be achieved. The only way to increase the coverage is to provide additional seed input data to the PRPG. The on-chip one time only programmable eFuse is used to store new PRPG seed data inputs and corresponding MISR output signature data for comparison. An XOR circuit option on the output of the MISR is operable to further compress the output data.

  • Publication number: 20180325712
    Abstract: Catheter for delivery of a medical device such as a stent or filter includes an inner tubular member and an outer tubular member movable relative to the inner tubular member. The outer tubular member is disposed at the distal end of the inner tubular member. The inner tubular member includes a fluid lumen defined therein, the fluid lumen having a fluid flow port directed to the exterior surface of the inner tubular member. A pressure chamber is defined by the inner tubular member, the outer tubular member, a proximal seal and a distal seal, and is in fluid communication with the fluid flow port, wherein fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to move the outer tubular member in a proximal direction allowing the medical device constrained by the outer tubular member to be released.
