Abstract: Disclosed are systems and techniques for a cloud function controller for executing code using graphics processing units (GPUs) in a serverless architecture. The techniques include generating, at cloud function controller, a first worker deployment request for a first worker and receiving a first registration of the first worker based on the first worker deployment request. The first worker is deployed in a first cluster environment having graphics processing unit (GPU) resources accessible to the first worker to process cloud function execution requests. The techniques include receiving an indication that the first worker is unavailable, generating a second worker deployment request for a second worker, and receiving a second registration of the second worker based on the second worker deployment request. The second worker is deployed in a second cluster environment having GPU resources accessible to the second worker to continue processing the cloud function execution requests.

Abstract: Disclosed herein are methods and systems for creating educational virtual reality environments. One or more cameras may capture 360-degree images of a medical environment. Each of the 360-degree images are captured with a camera being placed at a respective location. A computing device may create a virtual reality environment of the medical environment based on the 360-degree images, by, for each of the 360-degree images, placing a user viewpoint at the respective location of the respective camera that captured the respective 360-degree image, placing a graphical representation of a first class at each other respective location that is visible in the respective 360-degree image, and placing a graphical representation of a second class over each object visible in the respective 360-degree image that has particular educational content assigned to the object. The computing device may output, for interactive display at a virtual reality device, the virtual reality environment.

Abstract: The invention relates to a two-way approach to isolate, recover and upgrade 2,3-Butanediol (2,3-BDO) from fermentation broth. A complete separation and recovery process for 2,3-BDO using acetalization and trans-acetalization sequence. Acetalization with butyraldehyde using heterogeneous catalysts, either Amberlyst-15® or Nafion NR50®, efficiently isolates 2,3-BDO as phase-separated protected dioxolane. The approach provides significant process advantages with easy product recovery and high recyclability of the catalyst. Trans-acetalization of dioxolane with methanol (methanolysis) followed by distillation of acetal, yielded very high purity 2,3-BDO with about 90% isolated yield. Alternatively, dioxolane is used in a process direct to methyl ethyl ketone (MEK) as a BDO synthon allowing for recovery of the aldehyde.

Abstract: A process for the production of saturated or unsaturated aliphatic alcohols and/or hydrocarbons includes condensing acetone and/or alcohol(s) to form one or more carbonyl compounds, and hydrogenating and/or hydrodeoxygenating at least one of the one or more carbonyl compounds to form the saturated or unsaturated alcohol(s) and/or hydrocarbons. In some embodiments, the condensation of acetone and/or alcohol(s) may be carried out in the presence of a solid acid catalyst and a transition metal catalyst. The saturated or unsaturated aliphatic alcohols and/or hydrocarbons may include one or more saturated linear C9 alcohols, C9 alkanes and/or one or more mono-unsaturated C9 alkenes.

Abstract: Disclosed herein are embodiments of a method for making fuels and feedstocks from readily available alcohol starting materials. In some embodiments, the method concerns converting alcohols to carbonyl-containing compounds and then condensing such carbonyl-containing compounds together to form oligomerized species. These oligomerized species can then be reduced using by-products from the conversion of the alcohol. In some embodiments, the method further comprises converting saturated, oligomerized, carbonyl-containing compounds to aliphatic fuels.
