Abstract: Embodiments relate to the development of accelerators, and specifically to hydrated silicate aluminate accelerators. The accelerators can be blended with cement-containing compositions to form shotcrete (e.g., sprayed concrete) mixtures. The accelerators have improved properties over conventional sodium silicate accelerators, offering early strength development of shotcrete while maintaining or improving long-term strength.

Abstract: A sign device is disclosed. The device includes a mounting frame for mounting a light box to a surface of a vehicle; a lens frame for coupling to the mounting frame and movable between an open position and closed position; and a removable lens retainable by the lens frame such that, when the light box is activated with the lens frame in the closed position, the light box back lights the lens. In the closed position, a seal seals a space between the lens and the light box.

Abstract: Embodiments relate to the development of binder agents, and specifically to a hydrated silicate aluminate binder agents. The binder agents, whether combined or not with hardener agents, offer significant improvements in terms of mechanical strength and water resistance compared to soluble sodium-based silicates when used as agents for inorganic and organic substrates.

The genetic construct does not encode aromatic amino acid decarboxylase (AADC).

Abstract: The invention provides an anti-theft system for lithium batteries in golf carts, comprising an integrated hardware module that selectively enables or disables power output from the battery. A mobile application on a user device communicates with the anti-theft hardware through secure encrypted protocols. When activated, the system interrupts the power path between battery cells and output terminals, rendering the battery inoperable during unauthorized use attempts. The system incorporates tamper detection sensors that monitor physical interference and automatically alert users via the mobile application. Authentication mechanisms include biometric verification, passwords, and personal identification numbers to ensure only authorized users can control the functionality.

Abstract: The invention relates to expression vectors, and pharmaceutical compositions, and kits comprising the vectors, and, in particular, their use in methods for treating Parkinson's disease (PD), DOPA responsive dystonia, vascular parkinsonism, side effects associated with L-DOPA treatment for Parkinson's disease, L-DOPA induced dyskinesia, Segawa syndrome, or genetic dopamine receptor abnormalities.

Abstract: A device implanted within the heart and great vessels, such as a valve clip, includes inbuilt features that can allow its removal, partial or complete, at a later date. The inbuilt features include one or more conductors configured to conduct energy. The energy is used to separate the clip or part of the clip from the surrounding tissue. A system or kit to facilitate this removal includes an inner catheter having a distal end configured to engage and couple with the clip, and a conductor configured to conduct energy between a source of energy and the distal end of the inner catheter. A method to facilitate this removal involves transferring the energy to the clip to cause detachment and separation of at least part of the clip from the surrounding tissue and withdrawing at least part of the clip into an outer catheter.

Abstract: A system for selection of a medical provider (MP) by a requesting patient based on preferences for the MP includes a first model modeling the preferences of a plurality of patients for select MPs and trained on a first training data set. A second model is provided for modeling the preferences of a plurality of MPs for select patients and trained on a second training data set. A controller controls the first and second models to select at least a portion of available MPs in an available MP data set for input of the associated representative information to the first and second model MP inputs. A patient rank calculator accumulates the output patient determined preferences for MPs associated with the selected at least a portion of the available MPs and generates a MP ranking for each of the selected at least a portion of the available MPs.

Abstract: A cathode emitter assembly includes a cathode tube having a gas feed portion and a plasma outflow portion; an outer annular cathode insert in the plasma outflow portion of the cathode tube; an inner cathode insert in the plasma outflow section of the cathode tube; and an annular plasma emission portion defined between an inner surface of the outer annular cathode insert and an outer surface of the inner cathode insert.

Abstract: Provided is a process for authentication of a user on a mobile device. The user of the mobile device may authenticate with the mobile device, and credentials may be conveyed to a server via a relying device. The mobile device may directly communicate credentials to the relying device. In some examples, the user of the mobile device may authenticate using the mobile device without inputting credentials on the relying device. Credentials conveyed to the server by the relying device and authenticated by the server may permit user access to the relying device or access to an online resource from the relying device.

Abstract: A method of producing a material. The material is produced by the steps of: providing a geopolymer mixture or solution comprising an aluminosilicate and an alkali material; allowing the geopolymer mixture or solution to partially set to form an at least partially set geopolymer including pore spaces; and exposing the at least partially set geopolymer to a metal silicate solution or mixture containing a metal silicate to allow the metal silicate to enter the pore spaces and react to form additional material within the pore spaces. The material may be used in well-cementing and as an abandonment plug.
