Abstract: Provided herein engineered polypeptides that comprise a combination of spatially-associated topological constraints, wherein at least one constraint is derived from a CD25 reference target, and methods of selecting said engineered polypeptides. Further provided are methods of using the engineered polypeptides, including as positive and/or negative selection molecules in methods of screening a library of binding molecules such as antibodies. Further provided herein are CD25 antibodies selected using these engineered polypeptides.

Abstract: A strap tensioning buckle apparatus provides a ratchetless strap tensioning buckle apparatus for tensioning straps utilized in tying down objects. The ratchetless strap tensioning buckle apparatus has a base having a first end and a second end, a linkage pivotally attached to the base at a midpoint thereof, a handle having a first end and a second end, the handle having a shaft at the first end thereof for holding a loop of strap, the shaft further rigidly connecting the handle to the linkage, the handle pivoting via the linkage and moving the shaft in an arc from a first position to a second position, wherein moving the shaft from the first position to the second position tightens the strap and locks the strap in place.

Abstract: A client application includes a user interface for creating and editing complex interactions between IoT elements. Users choose from multiple IoT elements, where each element representing an IoT-enabled device or service. Users drag and drop selected IoT elements into a grid and couple them via one or more connectors. Users edit connectors and specify conditional requirements for some IoT devices to perform actions based on information sourced from other IoT devices. Users implement combinational logic by connecting multiple elements in different ways.

Abstract: An apparatus for controlling NOx emissions which includes a chamber having a wall surface and an interior, a flue gas entrance and a flue gas exit for a flue gas to enter and exit the interior of the chamber, a gas quenching zone in which the temperature of the gas can be lowered, an ozone injection and retention zone in the chamber, and a liquid spray zone including at least one spray nozzle for spraying a liquid towards the wall surface.
