Abstract: The present disclosure relates to a hypoxia-inducing cryogel, comprising one or more polymer and one or more hypoxia-inducing agent. The present disclosure additionally relates to a hypoxia-inducing construct, comprising a cryogel and a support. Methods of reducing concentration of oxygen in a medium, comprising contacting the medium with a hypoxia-inducing cryogel (HIC) or a hypoxia-inducing construct are disclosed. Additionally, methods of inducing hypoxia in a cell, comprising contacting the cell with a medium, wherein the medium comprises a HIC or a hypoxia-inducing construct are disclosed.

Abstract: Some embodiments are directed to an air intake grille assembly of a vehicle operable in forward and backward directions of travel across a surface. The air intake grille assembly can include a frame defining an opening. The air intake assembly can also include a plurality of louvers extending laterally across the opening, at least one of the plurality of louvers having a double curve shape defining first and second curve portions, wherein the first and second curve portions each have a different radius of curvature.

Abstract: Aspects of the present disclosure are presented for techniques in removing roughness and surface anomalies in structures with internal passages and intricate external surfaces, such as structures with internal fluid passages constructed by additive manufacturing (AM), using an abrasive slurry. Post processing methods which are capable of smoothing non-uniform surface roughness within intricate fluid passages are a prerequisite to the widespread adoption of AM for complex fluid systems. In some embodiments, a mixture of abrasive powder and deionized (DI) water is used to create a viscous slurry which can then be pumped through the internal fluid passages of a workpiece until the desired surface roughness is achieved. This abrasive flow machine (AFM) is capable of smoothing a wide range of roughnesses, internal geometries, and printable materials.

Abstract: Calibrated additive manufacturing processes can be used to manufacture constructs which can include or exclude heat exchangers incorporating fractal branched conformal cooling passages for use as molds, rocket engine components, and test articles. Described herein are the manufacture and use of conformal cooling of heat exchangers made by an additive manufacturing process.

Abstract: A mechanism for virtual time stamp counter acceleration is disclosed. A method of embodiments of the invention includes setting a virtual machine (VM) time stamp counter (TSC) to a hyper-fast rate, receiving control of the VM due to a VM exit caused by the VM issuing an instruction that reads the VM TSC, and adjusting the VM TSC with a value of an offset counter associated with the VM.
