Abstract: A wireless network comprises access points (APs) implementing roaming by way of handover of wireless devices between APs. Handover events over an analysis time interval are extracted from a wireless network log of the wireless network. Each handover event comprises a source AP from which a wireless device disconnects and a destination AP to which the wireless device connects. At least one handover frequency (HF) network topology graph is constructed fro the analysis time interval from the extracted handover events. The graph has nodes representing at least a subset of the APs of the extracted handover events and edges connecting pairs of nodes with each edge having a weight representing a count or frequency of handover events between the APs represented by the pair of nodes connected by the edge. A network diagnostic or visualization task is performed using the HF network topology graph.

Abstract: An apparatus for analyzing coronary vessels and a corresponding method are provided in which simulated pullback data obtained from (non-invasively) acquired diagnostic images is co-registered with invasively acquired intravascular pullback data and the co-registration is used to identify disparities in the pullback data obtained using the two modalities. These disparities allow for deriving further information about the vessel geometry and/or the blood flow through the vessel. They may therefore be used to improve the physiological model.

Abstract: The present application mainly relates to a method for determining a prognosis for a subject diagnosed with high-grade serous ovarian cancer. The method comprises determining the prognosis based on activities of at least two cellular signaling pathways including a phosphatidylinositide 3-kinase (PI3K) pathway and a nuclear factor-kappa B (NFkB or NF?B) pathway in a sample of the subject. The present application also relates to a method for identifying a subject diagnosed with high-grade serous ovarian cancer that will be suitable for a PI3K pathway targeting therapy or an NFkB pathway targeting therapy. The method comprises identifying the subject based on activities of at least two cellular signaling pathways including a PI3K pathway and an NFkB pathway in a sample of the subject. The present application further relates to corresponding apparatuses, non-transitory storage media, computer programs and kits.

Abstract: A fusion imaging system co-registers and fuses real time ultrasound images with reference images such as those produced by MRI or CT imaging. In an illustrated implementation, previously acquired CT or MRI or ultrasound images are loaded into the system. An ultrasound system is operated in conjunction with a tracking system so that the ultrasound probe and images can be spatially tracked. A computerized image processor registers the probe position with a reference image of the anatomy being scanned by the probe and determines whether the probe appears to be inside the skin line of the subject. If that is the case it is due to probe compression of the subject, and the reference image is modified to locate the skin line in the reference image in front of the ultrasound probe. The modified reference images can then be readily co-registered and fused with the ultrasound images produced by the probe.

Abstract: The present disclosure pertains to a system and method for providing mandibular advancement and sleep positional therapy to a user for a sleep session. The system is formed by a mandibular advancement device for treating obstructive sleep disordered breathing (e.g., obstructive sleep apnea and snoring) that includes an electronics module configured to aid in sleep positional training. The present system and method facilitate advancing a lower jaw of the user into a protruding position relative to an upper jaw of the user to increase a size of an airway of the user, determining whether a posture of the user has breached a posture threshold, and, responsive to a breach, prompting the user to change posture such that the posture of the user no longer breaches the posture threshold.

Abstract: A vacuum cleaner is described. The vacuum cleaner has a dirt inlet and a motor and fan for delivering suction to the dirt inlet. A cyclone unit separates particles from a suction flow. The cyclone unit has a vortex finder extending along a cyclone axis of rotation and an annular chamber formed around outside of the vortex finder. Air is delivered to the cyclone unit in a forward direction (i.e. in a direction from the dirt inlet to the cyclone unit). The cyclone axis of rotation is substantially parallel to the forward direction. An outlet from the vortex finder is at a backward end thereof such that the outlet is in an opposite direction to a forward component. A space beyond the vortex finder is a part of a dirt collection area, thus enabling a more effective collection of hairs and other debris.

Similar actions may be performed with a second input data segment to make a second determination of whether to accept or reject a second candidate conclusion. A final conclusion may be presented (522) based on the first and second determinations of the reinforcement learning trained agent with respect to at least the first candidate conclusion and the second candidate conclusion.
