Abstract: A method of performing an orthopedic procedure in the sacroiliac region. At least one aperture is formed that at least partially extends through at least one of an ilium and a sacrum. An undercutting system is at least partially inserted into the aperture. The undercutting system includes an insertion apparatus, a probe assembly and a cutting assembly. The probe assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The probe assembly is manipulated within a joint between the ilium and the sacrum while the probe assembly is in the extended position. The cutting assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The cutting assembly is sharper than the probe assembly. The cutting assembly is manipulated within the joint between the ilium and the sacrum while the cutting assembly is in the extended position to form a fusion region. The undercutting system is removed from the aperture.

Abstract: One or more embodiments of a digital content system allow a user to conveniently search and/or navigate through a collection of digital content items. In particular, a user can interact with a client device to search for and identify one or more digital content items within a collection of digital content items. For example, the digital content system may provide a photo from a collection of photos via a graphical user interface. The digital content system can receive a user input identifying a selection of one or more visual features within the photo. Based on the selected visual feature(s), the digital content system may identify photos from the collection of photos that include the identified visual feature(s) and provide access to the identified photos via the graphical user interface.

Abstract: Method for immobilizing proteins on a support, wherein the protein is incubated with the support in an aqueous phase in a discontinuous contact vacuum mixer dryer and the immobilized protein is then immediately dried, optionally following an optional washing step, in the same contact vacuum mixer dryer.

Abstract: A method of cutting tissue between a first bone and a second bone. An aperture is formed through the first bone. The aperture has a radius. An undercutting system is provided. The undercutting system includes a cutter. The undercutting system is extended into the aperture. The cutter is moved with respect to the undercutting system to an extended configuration where at least a portion of the cutter extends from the undercutting system. The cutter is used to cut tissue between the first bone and the second bone that is beyond the radius of the aperture. The undercutting system is removed from the aperture.

Abstract: Method of providing a geologic model (1?) representing a geologic feature based on geologic measurement data, such as seismic or electromagnetic data. The method comprises the following steps determining an initial model estimate. Further the method comprises, by means of a metric function, comparing features of a plurality of candidate traces (19) with known features of a model control point (3). For the candidate traces (19) where the metric function returns a similarity value above a similarity metric threshold, a model guide point (9) is arranged on the candidate trace (19) in question. The geologic model (1, 1?) is adjusted towards or onto such model guide points (9).
