A method includes measuring a density of the at least one gas; at least one of a) heating and b) cooling the at least one gas with a first thermal input; determining a first rate at which the at least one gas changes temperature when at least one of a) heating and b) cooling the at least one gas; comparing at least one of the density and the first rate to a reference database of gases; and determining at least one of a) a category b) a lower explosive limit and c) a concentration of the at least one gas.

Abstract: A distributed computing platform for isolating transaction nodes for managing energy post-trade processing. Plural participant computing systems each have a participant node module which executes a participant node on a decentralized computing network executing a smart contract in accordance with a decentralized protocol over a communication network. A reconciling computing system includes a reconciling module, a master database, a reconciling node module, and a reconciling distributed ledger interface module configured as an interface between the reconciling node module and other modules of the reconciling computing system. The reconciling node module is a node on the decentralized computing network. The reconciling computing system defines a domain of participant nodes on the decentralized computing network for each specific transaction which have access to trade data.

Abstract: Multi-mode personal transportation and delivery devices and methods of use are disclosed herein. A device can include a communications interface, the communications interface configured to provide vehicle-to-everything communications, a device controller comprising: a processor; and a memory for storing instructions, the processor executing the instructions to: receive a first message from a service provider that the transportation device is to relocate to a location based on user demand; and activate a redistribution mode to cause the transportation device to autonomously navigate to the location.

Abstract: This disclosure relates to a mask, and in particular a mask configured as a respirator. The disclosed mask is relatively low cost and relatively easy to manufacture. Further, the disclosed mask is reusable and customizable.

Abstract: A microfluidic device in which microfluidic channels are embedded in a culture medium chamber and have open sides. The microfluidic device is patterned with a fluid moved along a hydrophilic surface due to capillary force, and the fluid may be rapidly and uniformly patterned along an inner corner path and a microfluidic channel. In the microfluidic device, the microfluidic channel is connected to facilitate fluid flow with a culture medium through open sides thereof and openings, and thus may provide a cell culture environment in which high gas saturation is maintained. In addition, several microfluidic devices formed on one common substrate are described. Such microfluidic devices may be manufactured of a hydrophilic engineering plastic by injection molding.

Abstract: The invention provides a two-step tapered applicator, which can be used to deliver high-dose-rate vaginal brachytherapy to a female patient's vagina post-hysterectomy. In certain embodiments, once inserted through the female patient's vaginal opening (or introitus), the applicator of the invention causes less physical discomfort to the female patient than currently available applicators. In other embodiments, the applicator is used in a female patient whose vaginal apex is larger in diameter than her vaginal introitus.
