Abstract: Systems and methods for monitoring a subject for sleep apnea risk based on a bradycardia burden are disclosed. A sleep apnea monitoring system comprises a risk stratification circuit configured to detect bradycardia using cardiac information of the subject during a monitoring period, determine a bradycardia burden representing accumulated time or relative time of the subject being in the detected bradycardia over the monitoring period, and determine an apnea risk based on the bradycardia burden. An output unit can provide the apnea risk to a user, or to a process executed by an apnea detector to perform a confirmatory apnea detection.

Abstract: An inflatable barrier allows separating air in a first space from air in a second space to provide containment. The inflatable barrier may include an inflatable bag with edge seals in the form of parallel tubes. The bag receives air from an air mover through a first opening. It has a carrier for a vent that releases air while the bag stays inflated. A tension rod prevents the bag from bulging out of shape. The bag may be hung from an expandable rod. An internal channel may route air through the whole bag. The inflatable barrier may comprise an outer sleeve and two or more inflatable inner chambers. The circumference of a main sleeve matches the circumference of a combination of the inner chambers. The inner chambers include an air inlet/outlet. The outer sleeve may have connector halves to couple the barrier with another barrier, or to couple the main sleeve with a top, a bottom, or an extension.

Abstract: Embodiments may relate to pruning a distributed database for a peer-to-peer (P2P) network. A node may transmit a first multicast beacon over the P2P network. The node may receive a unicast synchronization request in response to the first multicast beacon, the unicast synchronization request comprising a removed list for the distributed database. The node may compare the removed list to a locally stored node list to determine a node removal. The node may determine if there is a failure in a node information call made to a node relating to the node removal. The node may, subsequent to a determination of the failure, update the locally stored node list based on the node removal. The node may transmit a second multicast beacon comprising the node removal. Nodes receiving the second multicast beacon may update a locally stored removed list using the node removal.

Abstract: A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked in a steam cracker to produce light olefins. A pyrolysis gas stream is separated into a light stream and a heavy stream. A light stream is separated into an aromatic naphtha stream and a non-aromatic naphtha stream. The aromatics can be saturated and thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.

Abstract: A seal assembly for a rotatable shaft assembly includes a seal housing and each of a main seal and a dust seal extending circumferentially around a seal housing center axis. The dust seal includes a radially inward dust seal lip, and is formed by a sealing layer having a plurality of ventilation openings formed therein, and a debris-blocking filter layer attached to the sealing layer and positioned across the ventilation openings. The main seal and dust seal assist in maintaining lubricating oil within a seal cavity. The dust seal prevents entry of debris whilst ventilating the seal cavity to limit carbonization of oil on seal assembly components. In an implementation the seal assembly is part of a rotatable crankshaft assembly.

Abstract: In an approach for dynamically generating correctly formatted Extensible Markup Language (XML) based off of a subset of data from a database, a processor receives an input pointing to a subset of data. A processor collects the subset of data from existing sources. A processor modifies the subset of data using wildcarding to generate a modified subset of data. A processor generates a set of XML files from the modified subset of data. A processor creates an immutable record of the subset of data, the modified subset of data, and the set of XML files. A processor outputs the set of XML files.
