Abstract: The present disclosure is directed to a multi-functional composition including activated carbon that is useful for injection into aqueous mediums such as soil or groundwater for sequestration of contaminants in a contaminated plume. The composition of activated carbon may include physical and chemical properties to enhance mechanism of contaminant physisorption and chemisorption including enhanced adsorption kinetics through manipulation of particle surface area, enhanced capacity and selectivity through controlled pore size distribution and enhanced electrostatic and hydrophobic interactions with contaminants. The multi-functional composition may further include a positively-charged nitrogen-functionalized organic compound and/or moieties that improve the activated carbon's ability to sequester contaminants in a subsurface environment.

Abstract: A neural processor. In some embodiments, the processor includes a first tile, a second tile, a memory, and a bus. The bus may be connected to the memory, the first tile, and the second tile. The first tile may include: a first weight register, a second weight register, an activations buffer, a first multiplier, and a second multiplier. The activations buffer may be configured to include: a first queue connected to the first multiplier and a second queue connected to the second multiplier. The first queue may include a first register and a second register adjacent to the first register, the first register being an output register of the first queue. The first tile may be configured: in a first state: to multiply, in the first multiplier, a first weight by an activation from the output register of the first queue, and in a second state: to multiply, in the first multiplier, the first weight by an activation from the second register of the first queue.

Abstract: Systems and methods for generating user interface elements associated with a guided workout are disclosed herein. For example, by analyzing location data associated with a user device, along with digital content corresponding to the guided workout, the system may generate user interface elements including graphical representations, segmented timelines, and performance metrics associated with a user's progress and performance while consuming the guided workout content. These interface elements may be displayed to the user during and/or after the workout and may allow for user interaction to view varying levels of detail associated with the interface elements.

Abstract: The ionic liquid-based coating is a coating for both porous and nonporous materials. As non-limiting examples, a porous substrate coated with the ionic liquid-based coating may be used to disinfect and remove microorganisms from air and water, to provide an antimicrobial surface for preventing microbial contamination, or to enhance filtration efficiency of the porous material for airborne and waterborne particulate matter without increasing flow resistance. As a further non-limiting example, a nonporous substrate coated with the ionic liquid-based coating may be used to form a surface capable of self-disinfection from microorganisms contacting surface. The ionic liquid-based coating includes at least one ionic liquid, an adhesive, and at least one additive, which may be a disinfectant, a viscosity modifier, a pH buffer, a fragrance, or combinations thereof.

Abstract: The present disclosure is directed to a multi-functional composition including activated carbon that is useful for injection or other application into soil or groundwater for removal (e.g., via adsorption) of inorganic contaminants in a contaminated plume. The composition of activated carbon may include physical and chemical properties to enhance the mechanism of contaminant physisorption and chemisorption including enhanced electrostatic interactions with contaminants. The multi-functional composition may further include one or more second materials (e.g., contaminant-selective agents) which comprise one or more compounds that improve the activated carbon's ability to sequester or otherwise immobilize inorganic contaminants in a subsurface environment.

Abstract: A sub-sea power delivery system includes a plurality of modular power converter building blocks on each of the power source side and the sub-sea load side that are stacked and interconnected to meet site expansion requirements and electrical load topologies. The power delivery system comprises a system DC transmission link/bus, wherein the system DC link is configured to carry HVDC or MVDC power from an onshore utility or topside power source to multiple sub-sea load modules. The stacked modular power converter topology on the sub-sea side of the sub-sea power delivery system is symmetrical with the stacked modular power converter topology on the on-shore/top-side of the sub-sea power delivery system.

Abstract: A load bypass switch enables continuous power to remote loads in the event of 1) failure of one or more remote loads, or 2) faults within the remote loads, within a dc power system. The bypass switch utilizes the passive components of the dc loads or inverters and therefore reduces overall component count. A black start method for the remote dc system uses the same passives present inside the loads/inverters and simultaneously uses some of the features of the bypass switch. A bypass-module-yard uses multiple bypass switches enabling continuous power to the remote loads in the event of failure of one or more power distribution cables (in-feed to the remote loads) located remotely in the dc system.
