Abstract: A database system is operable to determine a query for execution. A disjunction of a plurality of conjunctive normal form (CNF) filtering predicates is determined based on filtering predicates of the query. An IO pipeline is generated based on the disjunction of the plurality of CNF filtering predicates that includes, based on applying at least one type of optimization, at least one shared IO element common to multiple ones of plurality of the CNF filtering predicates. The IO pipeline is executed in accordance with execution of the query to generate a filtered subset of a plurality of rows that each meet at least one of the plurality of CNF filtering predicates.

Abstract: Methods, systems, and computer program products for direct assignment of physical devices to confidential virtual machines (VMs). At a first guest privilege context of a guest partition, a direct assignment of a physical device associated with a host computer system to the guest partition is identified. The guest partition includes the first guest privilege context and a second guest privilege context, which is restricted from accessing memory associated with the first guest privilege context. The guest partition corresponds to a confidential VM, such that a memory region associated with the guest partition is inaccessible to a host operating system. It is determined, based on a policy, that the physical device is allowed to be directly assigned to the guest partition. Communication between the physical device and the second guest privilege context is permitted, such as by exposing the physical device on a virtual bus and/or forwarding an interrupt.

Abstract: In general, the subject matter described herein relates to wettable materials that can be used to expose a liquid phase to a gas phase. An example method includes: providing a material including a polymeric substrate and at least one of: a silicate coating disposed over the polymeric substrate; or a polar mineral additive dispersed within the polymeric substrate at a loading from about 1% to about 25%, by weight; and using the material in a chemical process in which the material is at least partially covered by a liquid phase and the liquid phase is exposed to a gas phase.

Abstract: Computer-implemented systems and methods for automatically integrating a machine learning component to improve a spoken language skill of a speaker. The method includes selecting an anchor phrase and a target word as part of an interactive game, presenting a visual representation of the anchor phrase and the target word to the speaker, processing a received and digitized anchor phrase and target word with a speech engine, extracting a plurality of features from speech engine output with a feature extraction device and transmitting the plurality of features to a plurality of classifiers, deriving a plurality of classifier outputs from the plurality of features with the feedback classifiers and transmitting the plurality of classifier outputs to a resolver, selecting a feedback response with the resolver using a set of pre-defined rules based at least in part on the plurality of classifier outputs, and presenting the feedback response to the speaker.

Abstract: Embodiments of the invention disclose a virtual manipulative to facilitate math learning. The virtual manipulative comprises a user interface to progressively form one on more columns to hold partial sums or number decompositions to assist a learner in computing a sum.

Abstract: The present invention relates to a method of determining if a patient is pregnant and if the pregnancy is progressing. The method involves testing the patient a first time with a hCG home urine test, then after a select number of days, a second hCG home urine test is taken having a lower hCG sensitivity than the first.

Abstract: A hygienic device for protecting the genital, urinary and rectal areas of human beings during bathing and swimming activities as disclosed. The device is intended for protecting said areas against irritation, inflammation or infection. It is made of a flexible, thermoplastic and impermeable material and shaped to closely adhere to said areas by all its edges.
