Abstract: A system for predicting rare earth elements (REEs) in a feedstock sample includes a measurement instrument that records a measurement for a sample, a processor communicatively coupled to the measuring instrument, and a memory communicatively coupled to the processor and containing machine readable instructions that, when executed by the processor, cause the processor to correlate the measurement series using a model; and predict a presence of one or more rare earth element based at least in part on the correlation. A method for predicting rare earth elements includes measuring feedstock samples via XRF or PGNAA, to generate a measurements of elements of interest with a lower atomic weight than REEs; correlating the measurements with a model; and predicting a presence of one or more rare earth elements based at least in part on the correlation.

Abstract: A skin surface electrical stimulation device or electrode for use in the treatment of various conditions. The electrode has a plurality of conductive regions spaced from one another in predetermined positions around a non-conductive body that extends longitudinally from a head portion to a tail portion. At least two posterior conductors are positioned in the tail portion and spaced laterally from each other. One or more anterior conductors are positioned in the head portion and spaced longitudinally from the respective posterior conductors. An opening extends longitudinally rearwardly from an intermediate position in the body to split the tail portion into right and left portions. The electrode device is configured for placement proximate perineal area in an individual or animal for delivery of treatment via generating an electrical charge through respective conductors.

Abstract: A skin surface electrode used in the treatment of incontinence. The electrode has one or more conductive regions and an egress through which bodily fluid may pass without substantially adversely affecting tissue contact in the conductive regions of the electrode. The electrode is configured for placement proximate a patient's perineal tissues. An incontinence treatment system includes an electrode, wearable signal generator and interface module.

Abstract: Instruments and methods are provided for manipulating a bone anchor and a spinal fixation element. The instruments and methods disclosed herein are particularly suited to facilitate rotation of a bone anchor relative to another bone to correct the angular rotation of the vertebrae attached to the bone anchor. The instrument does not require the spinal fixation element to be inserted into the bone anchor prior to manipulation. The instrument further may be used in the insertion of the spinal fixation element into the bone anchor.

Abstract: Various spinal plating systems for use in treating spinal pathologies are provided. In certain exemplary embodiments, the spinal plating systems can be configured to allow a surgeon to select a bone screw construct having a particular range of motion for attaching a spinal plate to bone as needed based on the intended use. In one exemplary embodiment, the spinal plating system includes a first bone screw that is polyaxially movable relative to the spinal plate, and a second bone screw that has a range of motion that is substantially limited to a single plane.

Abstract: A bone adhesive application device has a pliable structure with an application surface upon which a bone adhesive may be applied. The application surface has a surface energy substantially equal to or less than a surface energy of the bone adhesive to reduce adhesion between the bone adhesive and the bone adhesive application device. The bone adhesive application device may be included in a kit for repairing bone defects having a bone adhesive formed from a reactive biocompatible polyurethane material. The bone adhesive may be applied to a bone defect by positioning the pliable structure over at least a portion of the bone defect, delivering the bone adhesive to the bone defect and removing the pliable structure from the bone adhesive.

Abstract: The disclosed embodiments provide a system including an implant assembly and an instrument configured to work in conjunction to manipulate vertebral bodies to affect derotation. The implant assemblies include a removable attachment element that allows for the attachment of the instrument. The instrument is configured to attach to two implant assemblies that have been inserted bilaterally into a vertebral body. When the instrument is attached to the implant assemblies, forces applied to the instrument are translated and transferred to the implant assemblies and the vertebral body into which the implant assemblies have been inserted thereby providing a rotational force on the vertebral body.

Abstract: A method for closing a sternum separated into at least a first sternum portion and a second sternum portion includes preparing at least one cut surface of at least one of the first or second sternum portions to have an adhesive applied thereon. The adhesive is applied to at least a portion of the at least one cut surface. The at least one cut surface is approximated to a second cut surface of the other of the first sternum portion or second sternum portion. As the adhesive cures, it bonds with the first cut surface and the second cut surface. Preparing the at least one cut surface may remove contaminants that could inhibit adhesion of the adhesive. The adhesive may be applied through adhesive injection holes formed along an incision separating the first and second sternum portions. Devices for preparing the cut surfaces and applying the adhesive are also provided.

Abstract: A method for sternal closure of a separated sternum includes applying an adhesive to a portion of an incision between at least a first sternum portion and at least a second sternum portion and maintaining the first sternum portion proximate to the second sternum portion until the adhesive has bonded with the first sternum portion and the second sternum portion. The adhesive may be applied over substantially the entire length of the incision or may be applied in intervals. The method for sternal closure may also include compressing the first sternum portion and the second sternum portion together using one or more compression devices and introducing adhesive to contact regions where the compressive devices contact the sternum. The method may also include cutting an interface feature in the first and second sternum portions or spanning the incision between the first and second interface portions with a structural support.

Abstract: A composition includes a siloxane of the formula: (RMe2SiO1/2)a(MeRSiO2/2)b(RSiO3/2)c(SiO4/2)d wherein a is at least 2, b is from 3 to 20, c is from 0 to 10, d is from 0 to 10, and each R is independently of the formula —CR?2—CR?2—Y—Z or CR?2—CR?2—Z, wherein each R? is independently a hydrogen atom or a C1 to C10 hydrocarbyl free of aliphatic unsaturation so long as at least one R? is a hydrogen atom, Y is a divalent organic group, and Z is a polycyclic group containing at least one aromatic ring. A method of making the siloxane includes charging (HMe2SiO1/2)a(MeHSiO2/2)b(HSiO3/2)c(SiO4/2)d, a platinum catalyst, and an alkene of the formula CR?2?CR?—Y—Z or CR?2?CR?—Z into a reactor to form the siloxane. The siloxane is useful as a component in holographic storage media for photopolymer-based holographic data storage applications. The siloxane exhibits excellent compatibility when mixed with a polymerizable component before the polymerizable component is cured.
