Abstract: Disclosed are hierarchical buoyant materials comprising porous components having multiple length scales that provide reduced density, higher strength, and improved buoyancy. The hierarchical buoyant materials include components having at least two length scales including a first porous material having elements characterized by a first linear length scale and a second porous material having elements characterized by a second linear length scale. The first porous material includes hollow microspheres, and the second porous material provides low effective density via geometrical arrangements. The second linear length scale is substantially different than the first linear length scale in terms of size, e.g., diameter, length, or distance.

Abstract: An electronic device may be provided with control circuitry, wireless transceiver circuitry, and a display. The electronic device may be used to provide information to a user in response to being pointed at a particular object. The control circuitry may determine when the electronic device is pointed at a particular object using wireless control circuitry and/or motion sensor circuitry. In response to determining that the electronic device is pointed at a particular object, the control circuitry may take suitable action. This may include, for example, displaying information about an object when the electronic device is pointed at the object, displaying control icons for electronic equipment when the electronic device is pointed at the electronic equipment, and/or displaying a virtual object when the electronic device is pointed at real world object.

Abstract: An experiment design is determined for a plurality of physical experiment entities, based on a training loss that is dependent on a critic function and an action parameter individually associated with each physical experiment entity, with the aim of increasing (e.g., optimizing) information gain with respect to a plurality of test entities. The training loss encodes a predicted information gain between a predicted experiment outcome and a predicted test quantity. The predicted experiment outcome associated therewith is sampled from a joint probability distribution based on an entity context. A numerical output is computed using the critic function applied to the predicted experiment outcome and the predicted test quantity.

Abstract: A flow tube is axially moveable within an actuator body between a first axial position and a second axial position for actuating a downhole tool, such as for closing a subsurface safety valve. The flow tube includes an interior flow bore for conveying fluids from the tubing string through the actuator body. An external flow tube profile defined on the flow tube includes an upper shoulder for engagement with a wiper in the first axial position, a lower shoulder for engagement with the wiper in the second axial position, and a clearance path between the upper and lower shoulders for allowing viscous flow past the wiper when the flow tube is moved between the first and second axial positions.

Abstract: A computer-implemented method comprising: accessing a machine learning, ML, model that is operable to sample a causal graph from a graph distribution describing different possible graphs, wherein nodes represent the different variables of said set and edges represent causation, and the graph distribution comprises a matrix of probabilities of existence and causal direction of potential edges between pairs of nodes, and wherein the ML model is trained to be able to generate a respective simulated value of a selected variable from among said set based on the sampled causal graph. The method further comprises using the ML model to estimate a treatment effect from one or more intervened-on variables on another, target variable from among the variables of said set.

Abstract: An authorization level is set at enrollment. The authorization level can be determined based on user identity and a class of authentication. The class of authentication can be associated with strength of authentication related to a channel employed to enroll a user for access to products or services. Authorization level can also be determined based on initiation information regarding the user, a device of the user, or both. Access to the products or services can be selectively controlled based on the authorization level.

Abstract: Techniques for electronic calendar management. Electronic computing device(s) is/are used to generate an electronic message comprising at least one indication of a proposed electronic calendar entry. The electronic computing device(s) transmit the electronic message to a recipient. The electronic computing device(s) receive, after the electronic message has been received by the recipient, a request for one or more images corresponding to the at least on indication of a proposed electronic calendar entry. The electronic computing device(s) check in response to receiving the request, at least one electronic calendar to determine a status of the calendar at a time corresponding to each of the at least one proposed electronic calendar entry. The electronic computing device(s) generate, for each proposed electronic calendar entry for which corresponding time is available, a graphical representation of each available proposed electronic calendar entry.

Abstract: A wellbore system comprising an autofill and circulation assembly comprising a housing defining a flowbore and comprising a first port and a second port, and a first sleeve slidable within the housing from a first position to a second position and from the second position to a third position, when the first sleeve is in the first position, the assembly allows fluid communication from an exterior of the housing to the flowbore via the first port and does not allow fluid communication from the flowbore to the exterior of the housing via the first port, when the first sleeve is in the second position, the assembly allows bidirectional fluid communication between the exterior of the housing and the flowbore via the second port, and, when the first sleeve is in the third position, the assembly disallows fluid communication between the exterior of the housing and the flowbore.

Abstract: A sliding sleeve apparatus that has a flow inhibitor that slows the fluid flow between the interior passageway of the sliding sleeve and the well annulus to allow pressure equalization between the interior passageway of the sliding sleeve and the well annulus to occur prior to placing the sliding sleeve in a fully open position. The inhibited or restricted fluid flow reduces wear on the seals and other components of the sliding sleeve, which extends the operative life of the tool.
