Abstract: A bending apparatus for a sample is disclosed. The bending apparatus includes a translation mechanism that translates a vertical displacement/force into a horizontal displacement/force for bending. Components of the bending apparatus are fabricated from a strong, radiolucent material. In these ways, the bending apparatus is compatible with micro-CT imaging, and as such, may be used to bend a sample during imaging. In a particular application, the bending apparatus may be used to measure biomechanical properties of a bone, such as bone strength, bone material properties, fracture toughness, and fracture propagation.

Abstract: An example tunnel junction ultraviolet (UV) light emitting diode (LED) is described herein. The UV LED can include a mesa structure having at least one of: an n-doped bottom contact region, a p-doped region, and a tunnel junction arranged in contact with the p-doped region. Additionally, a geometry of the mesa structure can be configured to increase respective efficiencies of extracting transverse-electric (TE) polarized light and transverse-magnetic (TM) polarized light from the tunnel junction UV LED. The mesa structure can be configured such that an emitted photon travels less than 10 ?m before reaching the inclined sidewall.

Abstract: The present disclosure provides methods for freeform extrusion-based additive manufacturing via a robotic arm. In specific aspects, methods are particularly provided for minimally invasive, intracorporeal three-dimensional printing of biocompatible materials. An end effector of a robotic arm includes a sharp member and a reservoir filled with a printing material. The provided method may include piercing a substrate with the sharp member. A bulb or microbolus of material may be extruded beneath the substrate surface to act as an anchor. The end effector may be manipulated to extrude biomaterial along a printing path. Periodically along the printing path, the sharp member is used to pierce the substrate surface create additional respective anchors. In some instances, the method may terminate after extruding material to form a single layer construct. In other instances, the method includes forming one or more layers on top of the initial base layer anchored to the substrate.

Additionally, the magnetic core can include a plurality of teeth defining a plurality of slots between adjacent teeth. The stator winding can also include a first portion arranged inside a slot and a second portion arranged outside the slot. The method can further include optimizing, using a computing device, a geometry of the first portion of the stator winding, where the first portion of the stator winding in the provided electric machine has the optimized geometry.
Abstract: A device used in conjunction with fixation hardware to provide a two-stage process to address the competing needs of immobilization and re-establishment of normal stress-strain trajectories in grafted bone. A method of determining a patient-specific stress/strain pattern that utilizes a model based on 3D CT data of the relevant structures and cross-sectional data of the three major chewing muscles. The forces on each of the chewing muscles are determined based on the model using predetermined bite forces such that a stiffness of cortical bone in the patient's mandible is determined. Based on the stiffness data, suitable implantation hardware can be designed for the patient by adjusting external topological and internal porous geometries that reduce the stiffness of biocompatible metals to thereby restore normal bite forces of the patient.

Abstract: Signal processing techniques that can include an embedded software low-noise response pulse detection, which can help provide an enhanced signal-to-noise characteristic, such as can help permit highly specific fast IR spectroscopic tissue analysis. Using a difference between (1) response signal values during a first time period duration of a response pulse from a tissue sample illuminated by illumination pulse, and (2) response signal values for a similar first time period duration between response pulses, for a low duty cycle (e.g., less than 50%, 10% or even at about 5% duty cycle) illumination pulse, accumulation of noise in the response signal between electromagnetic illumination pulses can be limited. In particular, the described signal pre-processing techniques can help extract meaningful information for performing spectroscopic analysis and characterization of the tissue sample despite amplitude and temporal variations that can be encountered when using the system.
