    Abstract: A content delivery network (CDN) includes UE gateways, a service switch (SS) mesh network, and server gateways. The CDN nodes maintain cache lists of mappings identifying corresponding upstream system nodes for content items available at content servers connected to the server gateways. When a CDN node receives an upstream service instance request for a specific content item by a corresponding UE connected to a UE gateway, upon determining that a mapping for the specific content item is in its cache list, the CDN node forwards the upstream service instance request to the corresponding upstream system node as part of a process of defining a downstream data path for the specific content item from the corresponding content server to the corresponding UE. The CDN enables service-level content delivery at lower levels of latency than conventional DNS-based systems.

    Abstract: According to an update procedure for a network of interconnected nodes, a node keeps track of markers received on the node's incoming channels, transmits a marker on each outgoing channel (if any exist), and updates its node configuration from an old configuration to a new configuration. In one version of the update procedure, the node updates its configuration and transmits markers after receiving its initial incoming marker. In another version for acyclic networks, the node updates its configuration and transmits markers after receiving its final incoming marker. The node determines how to handle (i.e., process, queue, or drop) each incoming data packet based on (i) whether or not it has updated its node configuration yet and (ii) whether or not it has received a marker on the corresponding incoming channel yet. A controller initiates the update process at a subset of nodes that ensures eventual completion of the update process.

    Abstract: A method is described for testing the viability of a tissue of a patient for an anastomosis using a perfusion measuring device wherein the method may comprise: controlling at least one actuating structure of the perfusion measuring device to rapidly ramp up a force exerted on at least one test area of the tissue selected for an anastomosis, the force exerted on the at least one test area defining a local (systolic) perfusion pressure; and, during the ramp up of the force, the computer receiving a sensor signal from at least one sensor of the perfusion measuring device and a signal from a blood pressure device, the sensor signal being indicative of perfusion of blood through the micro vascularization in the first test area and the blood pressure signal being indicative of a general (systolic) blood pressure of the patient; controlling the first actuating structure to slowly ramp down the force exerted on the first test area, when the sensor signal signals the computer that the perfusion of the blood in the tissue of the first test area has stopped; and, during the ramp down of the force, the computer determining the local perfusion pressure at which the sensor signal indicates a start of perfusion of blood through the micro vascularization, the determined local perfusion pressure defining a reperfusion pressure value of the first test area; and, determining a prediction whether or not the tissue of the at least one test area is viable for an anastomosis on the basis of the local reperfusion pressure value of the at least one test area and the general systolic blood pressure value.

    Abstract: Various example embodiments relate to power saving in a wireless communication network and, in particular, an apparatus and a method to determine a threshold to establish whether a cell of a group of cells supporting network coverage in an area of a wireless communication network should enter or exit a power saving mode. In particular, aspects may provide: prediction circuitry configured to predict a future load in a group of cells supporting network coverage in an area of a wireless communication network based on historical load data for the group of cells; and determination circuitry configured to determine, based at least on the predicted future load, at least one threshold load value for establishing whether a cell of the group of cells should enter or exit a power saving mode.

    Abstract: Methods and systems for determining interaction between cells are described wherein the method includes determining or receiving a sequence of images representing manipulating first cells, in a holding space, the holding space including a functionalized wall comprising second cells, the manipulating including settling of the first cells onto the functionalized wall and applying a force on the settled first cells; detecting groups of pixels representing first cells in first images representing the settling of the first cells onto the functionalized wall; tracking locations of detected first cells in the first images; and, determining settling events, a settling event being determined if a cell in a first image is not distinguishable from background of the first image, the location in the image at which a cell settling event is detected defining a cell settling location; detecting groups of pixels representing cells in second images captured during the application of the force and tracking locations of detected cells, wherein tracked locations of a detected cell in the second images form a tracking path, the first location of the tracking path defining a pop-up event, the location in a second image at which a pop-up event is detected defining a pop-up location; and, determining detachment events based on the settling locations and based on the pop-up locations, a detachment event defining a first cell being detached from a second cell due to application of the force on the first cell, and determining information about the interaction between first and second cells based on the force applied to the first cells.
