Abstract: A device for minimally invasive bone harvesting surgery described herein includes a cutter, a sleeve, and a drive control system. The cutter includes a head and a spiral conveying portion. An external screw thread is disposed on a surface of the spiral conveying portion, the sleeve is sleeved on the cutter, and the head and at least a part of the screw thread of the surface of the spiral conveying portion are exposed from the sleeve. The drive control system drives and controls the cutter to work. The device for minimally invasive bone harvesting surgery in this invention only needs a very tiny skin incision and bone window, cuts or grinds cancellous bone to bone fragments and then conveys them through a screw thread channel, which realizes the oriented conveying of the harvested bone.

Abstract: A content item generation system which implements techniques for selecting and identifying content items to return in response to a request is described. For example, the content item generation system may separate requirements included with a request into first and second sets of requirements. The first set of requirements may be used to identify which content items or content item campaigns may be suitable to respond to the request. The second set of requirements may be used to determine whether items associated with the selected content items or content item campaigns correspond to technical requirements specified in the request.

Abstract: A request filtration system that implements techniques to reduce load on a downstream service by efficiently filtering requests before they are processed by the downstream service. The request filtration system may be used by a request processing system to eliminate requests that satisfy any of one or more filters. For example, each filter specifies one or more attributes that may apply to one or more requests. If a request satisfies a filter, then the request is not considered by the downstream service or a content item does not need to be selected by the request processing system in response to the request.

Abstract: A request intermediary processing system which implements techniques to allow tracking of responses to requests when there is an intermediary. In an embodiment, the intermediary includes an internal exchange.

In response to receiving the content request, an entity profile of an entity that is associated with the identifier is retrieved. A content item is identified based on the entity profile. Based on a content item identifier that identifies the content item, a particular campaign objective from among a plurality of campaign objectives is determined. A particular format for, or particular content to include with, the content item is determined based on the particular campaign objective. A rendered content item is generated based on the content item and at least one of the particular format and the particular content and the rendered content item is displayed on a screen of a computing device.

Abstract: Composite materials containing sulfurized polymers and sulfur-containing particles can be used in lithium-sulfur energy storage devices as a positive electrode. The composite material exhibits relatively high capacity retention and high charge/discharge cycle stability. In one particular instance, the composite comprises a sulfurized polymer having chains that are cross-linked through sulfur bonds. The polymer provides a matrix in which sulfide and/or polysulfide intermediates formed during electrochemical charge-discharge processes of sulfur can be confined through chemical bonds and not mere physical confinement or sorption.
