Abstract: A liquid sampling system includes a liquid sampling valve for transferring a liquid sample from a primary stream to a secondary stream. The liquid sampling valve includes a rotor having a movable shuttle that is in selective fluid communication with the primary stream or the secondary stream. The rotor shuttle passes through a discharge station prior to completion of the valve cycle to discharge contaminants prior to re-exposure to the primary stream.

Abstract: A fast snapshot is configured to determine if a snapshot is utilized for asynchronous mirroring. The fast snapshot operation is performed by avoiding reference counts of the one or more data units associated with the snapshot from being updated at a creation time and a deletion time when the snapshot is utilized for asynchronous mirroring.

Abstract: Methods, computing systems and computer program products implement embodiments of the present invention that include mirroring, in a distributed storage system having multiple storage nodes, data on the storage nodes. Upon the distributed storage system detecting a loss of communication with a given storage node, a log including updates to the data stored in the given storage node is recorded and, the recorded updates can be applied to the given storage node upon communication with the given storage node being reestablished. In some embodiments, the distributed storage system may be configured as a software defined storage system where the storage nodes can be implemented as either virtual machines or software containers. In additional embodiments, upon detecting the loss of communication, a redistribution of the mirrored data among remaining storage nodes is initiated upon detecting the loss of communication, and the redistribution is rolled back upon reestablishing the communication.

Abstract: Provided are a computer program product, system, and method for determining the location for volumes of data being initially stored within a storage space, regardless of the physical location of the data. The storage space includes stripes composed of volumes, which can be logically represented as a utilization histogram of stripe locations offset from one another. Sometime the stripes are fully allocated with one large volume or partially allocated with multiple, arbitrary-sized smaller volumes. When there are multiple smaller volumes that do not utilize all of the available stripe space, gaps form. To minimize the creation of such gaps, when a volume of data is initially stored, a start location to place the volume of data is selected by using selection criteria as guidance.

Upon the event processing system, an event message from a computing system via a one-way firewall and matching the computing device preferences to the event message, the event processing system can convey the token and the event message to a push notification system. In some embodiments, upon the push notification service receiving the token and the event message, the mobile device can be identified based on the token, and the event message can be conveyed to the computing device. The event messages may include a severity level, and the preferences may include a severity threshold and a message detail level.

Electrodes are used to deliver a direct current to the gingival tissues of a mouth in order to achieve a number of therapeutic, prophylactic, and regenerative benefits. These benefits include killing oral microbes, increasing oral vasodilation, reducing oral biofilm, improving oral blood circulation, reversing oral bone resorption, promoting oral osteogenesis, treating gum recession, and fostering gingival regeneration. Other benefits include the treatment of gingivitis, periodontitis, and oral malodor, and other systemic diseases correlated with oral pathogens.

Abstract: Provided are a computer program product, system, and method for generating a configuration page for rendering in a graphical user interface (GUI) for managing provisioning of storage resources in a storage system. A determination is made of allocation commitment certainties for virtual storage ranges to allocate from the storage system based on physical capacity in the storage system and an estimated data reduction rate. Each of the allocation commitment certainties indicates a likelihood that a corresponding of the virtual storage ranges will be available for allocation in the storage system. Visual representation of a plurality of user selectable storage spaces indicating the allocation commitment certainties for the virtual storage ranges in the user selectable storage spaces are rendered in the configuration page. A user selection graphic that when selected provisions a selected of the user selectable storage spaces in the storage system is rendered in the configuration page.

Abstract: Provided are a computer program product, computer system, and method for utilization of a thin provision grid storage array. Storage devices are divided into a plurality of slices, wherein each of the slices has a same number of partitions. Volumes in a pool are configured, wherein the pool is associated with physical capacity of a slice, wherein a volume size is unlimited, and wherein a cumulative size of all volumes in the pool is unlimited. While data is being written to the volumes in the pool, partitions of a first slice of the plurality of slices are allocated to the volumes in the pool and, in response to determining that the first slice needs additional physical capacity, allocating a partition of a second slice to the first slice by updating a mapping table.

Abstract: A method and device for setting a predetermined radial gap width for rotor blades arranged in a housing of a turbomachine is provided. The method includes removing a housing part and at least partially exposing the rotor blades which are to be machined, arranging a grinding device in the region of a rotor blade which is to be machined such that the tip of the rotor blade is machined using a grinding disk of the grinding device, screening off the machining region by arranging a screening device which is formed so as to counter a release of grinding dust from the screen off machining region, providing a suction extraction such that it extracts grinding dust from the screened-off machining region and grinding the tip of the rotor blade in situ producing the radial gap width.

Abstract: Exemplary method, system, and computer program product embodiments for efficient state tracking for clusters are provided. In one embodiment, by way of example only, in a distributed shared memory architecture, an asynchronous calculation of deltas and the views is performed while concurrently receiving client requests and concurrently tracking the client requests times.
