Abstract: A surgical head clamp and robotics platform secures a head of a patient and positions an instrument relative to the head for a medical procedure. The head clamp and robotics platform comprises a planar C-shaped frame for at least partially encircling the head of a patient. An instrument arm is mounted is to a free distal end of one arm member of the frame. The instrument arm extends away from the arm member in a direction transverse to the plane of the frame. The instrument arm includes a base mounted to the arm member for movement along, three degrees of freedom relative to the frame, a proximal portion extending from and pivotally connected to the base, and a distal instrument holder extending from and pivotally connected to the proximal portion. The instrument arm functions to selectively position the instrument in an angular position relative to the head clamp.

Abstract: A needle steering system and apparatus provides active, semi-autonomous control of needle insertion paths while still enabling a clinician ultimate control over needle insertion. A method and system controls the needle path as the needle is inserted by precisely controlling the rotation of the needle as it continuously rotates during insertion. This enables underactuated 2 degree-of-freedom (DOF) control of the direction and the curvature of the needle from a single rotary actuator. Control of the rotary motion is therefore decoupled from the needle insertion. The rotary motion controls steering effort and direction, while the insertion controls needle depth or insertion speed. In one implementation, the proposed method does not require constant velocity insertion, interleaved insertion and rotation, or known insertion position or speed. The insertion may be provided by a robot or other automated method, may be a manual insertion, or may be a teleoperated insertion.

Abstract: An in vitro meat having non-decellularized leaf scaffold and a method for producing an in vitro meat using non-decellularized leaf scaffold are described herein. The method includes preparing a non-decellularized plant leaf and incubating the leaf in a cell culture media to obtain a non-decellularized leaf scaffold; seeding the leaf scaffold with a population of muscle cells to obtain a leaf scaffold adhered population of muscle cells; and growing the leaf scaffold adhered population of muscle cells in cell culture media thereby obtaining the in vitro meat.

Abstract: A petroleum refining method for upgrading petroleum products improves the efficiency and reduces the costs of upgrading oils, such as lipids, bitumen, crude oil, fracking oils, synthetic oils, and other feeds, to produce useful fuels and chemical precursor streams. Usage of a specific type of zeolite (ZSM-5) catalyst, supercritical water to control coke formation, and a specific response to phase behavior and other catalytic effects optimize the process. A prescribed set of reactor conditions employing supercritical water increases activity of the catalyst in industrial reactions.

Abstract: Recovery of scandium from mined red mud includes adding an acid to a quantity of red mud for converting oxides in the red mud, and roasting the quantity of red mud for decomposing compounds having low thermal stability, typically iron and titanium. Water is added to the roasted red mud for leaching the converted oxides into a leach liquor mixture including scandium and other dissolved rare earths, and the leach liquor mixture is agitated by sonication or ball milling to increase an exposed surface area of red mud particles in the leach liquor. PH of the leach liquor is adjusted to precipitate the rare earths while leaving the scandium in solution in the leach liquor, followed by precipitating the separated scandium oxalate remaining in the leach liquor by reducing the pH and adding oxalic acid. Precipitated scandium oxalate may then be filtered from the leach liquor.

Abstract: In some embodiments, there is provide a method of analysing a bone fracture, comprising; stabilizing a bone having a fracture including a first support point located distal of the fracture and a second support point located proximal of the fracture; applying a force to an area of the bone having the fracture to cause a displacement of the fracture; imaging the bone during the application of force thereto; and comparing the image of the bone during the application of force to an image of the bone without the application of force to determine the state of the fracture.

Abstract: A thermal storage composition is defined by a polymer having thermally responsive absorption or passage capabilities based on an Upper Critical Solution Temperature (UCST) or Lower Critical Solution Temperature (LCST), and a sorbent in fluidic communication with the polymer. A fluid such as water conveys thermal energy between the polymer and the sorbent based on an identified target temperature that acts as a thermostat for synergistic fluid release and transfer between the polymer and sorbent that stores and releases heat energy in a cyclic manner. The composition includes a synergistic integration of a sorbent and selectively hydrophilic polymer to alternately hydrate according to a target temperature based on the UCST of the water/sorbent combination.
