Abstract: A peritoneal dialysis system includes a control unit configured to (i) store a sleep state pattern for the patient, (ii) begin a patient drain followed by a patient fill when at least one sensor indicates that the patient is in a deep sleep state, (iii) extend a dwell period if the sleep state pattern indicates that the patient will enter a subsequent deep sleep state within a first time duration after a programmed dwell period, and (iv) shorten the dwell period if the sleep state pattern indicates that the patient will leave the deep sleep state within a second time duration after an end of the programmed dwell period. The system alternatively or additionally assesses or records a stress level of and/or a fluid/caloric intake by the patient and takes actions accordingly.

Abstract: Computing devices, methods, systems, and computer-readable media for analyzing requests to perform cold restores of cryptocurrencies are described herein. A computing device may receive a request for a cold restore of one or more cryptocurrencies stored by a digital wallet. The one or more cryptocurrencies may be identified, and data may be received from a database. The computing device may determine, based on the data, a risk score associated with the transfer of the one or more cryptocurrencies from a cold state to a hot state. The risk score may be generated using a machine learning model, such as a machine learning model that may be trained to output a risk score associated with a cold restore based on recent transaction activity. The computing device may output, based on comparing the risk score to a threshold, an indication of whether the request should be granted.
