Abstract: Systems and methods for determining molecular structures based on atomic-orbital-based features are described. Atomic-orbital-based features can be utilized in combination with machine-learning methods to predict accurate properties, such as quantum mechanical energy, of molecular systems.

Abstract: A structural brace for a pre-fabricated housing module includes (a) a temporary beam connecting two opposite side walls of the pre-fabricated housing module along an open side of the pre-fabricated housing module; (b) ceiling bracing panels each providing horizontal temporary structural support between a third side wall of the pre-fabricated housing module and the temporary beam; and (c) wall bracing panels each providing temporary vertical structural support between the temporary beam and a floor of the pre-fabricated module. A further transverse beam may be provided to connect the ceiling bracing panels for greater structural support and to facilitate lifting of the module during transportation. A tarp may be provided to cover the top and exposed sides of the pre-fabricated housing module to prevent damage to the interior on route to an installation site.

Abstract: A system and a method regulate temperature in a building using an air inlet at a level beneath a space for habitation within the building (e.g., living areas in a residential building, or work areas or offices in a commercial building). The air pulled into the air inlet creates an air flow into the building that is received into a thermal storage plenum, which allows the air flow to mix with a substantial air mass accumulated in the thermal storage plenum. The air in the thermal storage plenum is circulated throughout the space for habitation and recycled back to the thermal storage plenum through, for example, a return duct. Such a return duct may be provided by a stairwell. A relief vent may be provided at a level above the space for habitation for the air flow to exit the building. The quantity of air flowing through the air inlet and the relief vent may be controlled using a control system which open the air inlet and the relief vent simultaneously.
