Abstract: A retrievable stent configured to be positioned across the ductus arteriosus in a pediatric human patient to keep the ductus arteriosus open and ensure adequate blood flow is described. The retrievable stent can include a plurality of 4 to 8 struts that extend from a proximal end connector to a distal end tip, each having a curved proximal strut end, a curved distal strut end and an elongated strut body portion that extends from the curved proximal strut end to the curved distal strut end. When the stent is positioned in the ductus arteriosus, the curved proximal strut ends and the curved distal strut ends engage the ductus arteriosus to provide the radial force necessary to keep the ductus arteriosus open while the elongated strut body portions minimally engage the ductus arteriosus to prevent invagination into the vascular wall and thus allow for subsequent retrieval.

Abstract: A catalyst suitable for use in carbon oxide conversion reactions is described, said catalyst in the form of a shaped unit formed from an oxidic catalyst powder, said catalyst comprising 30-70% by weight of copper oxide, combined with zinc oxide, alumina and silica, having a Si:AI atomic ratio in the range 0.005 to 0.15:1, and having a BET surface area >105 m2/g and a copper surface area >37 m2/g catalyst. The catalyst is prepared by a co-precipitation method using an alumina sol.

Abstract: There is described a machine learning system comprising a first subsystem and a second subsystem remote from the first subsystem. The first subsystem comprises an environment having multiple possible states and a decision making subsystem comprising one or more agents. Each agent is arranged to receive state information indicative of a current state of the environment and to generate an action signal dependent on the received state information and a policy associated with that agent, the action signal being operable to cause a change in a state of the environment. Each agent is further arranged to generate experience data dependent on the received state information and information conveyed by the action signal. The first subsystem includes a first network interface configured to send said experience data to the second subsystem and to receive policy data from the second subsystem.

Abstract: A system and method for dynamically marketing cattle is provided comprising a buyer interface, a producer interface, a network, and a cattle information server. The cattle information server receives information from the buyer interface defining a plurality of demand profiles at least one which contains information specifying a first pre-conditioning program. The cattle information server also receives information from the producer interface defining a supply profile that specifies a second pre-conditioning program and stores the demand profiles and supply profile in a database. The cattle information server searches the database to determine if one or more of the demand profiles match the supply profile based at least in part on a comparison of the first and second pre-conditioning programs and identifies at least one demand profile in response to a match between the supply profile and the demand profile.

Abstract: The mass flow rate sensor includes a waveguide disposed in a flow passage having a bluff body facing in an upstream direction. Waves are pulsed along the waveguide for interaction with the fluid. A receiver is coupled to the waveguide to detect a propagated wave and provides a first output signal proportional to the transit time of the propagated wave for determining fluid density. The receiver also provides a second output signal proportional to the shedding frequency of vortices from the waveguide to determine velocity. An electronics module calculates mass flow rate from the velocity times density times area of the flow passage and a constant. In other forms, the velocity is ascertained by transmitting an ultrasonic beam through the shedding vortices to determine vortex frequency which is proportional to velocity.

Abstract: An in-line formed web having major surfaces in the X-Y plane and a depth in the Z direction is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web contains multiple layers of composite material which may have both thermoplastic fibers and absorbent material. The multiple layers can have different compositions of thermoplastic fibers and absorbent material as applied in-line by various arrangements of thermoplastic melt dies and absorbent fiber dispensers. By arranging at least two of the multiple layers in an opposing relation overlaid in the Z-axis direction of the web, a gradient can be formed in the Z-direction of the web. By coordinating the timing and deposition of the material onto a forming wire, at least one of the multiple layers is arranged to have zones of intermittent material deposition in at least one of a machine direction or a cross direction of the web.
