Abstract Optical Metasurfaces (MSs), a new class of planar optical elements, are profoundly disrupting the field of optical design, notably due to their compactness, multi-functionalities, and device integrability.Relying on planar nanofabrication processes closely akin to Tidbit the semiconductor industry, metasurface technology could benefit from
Large numbers of dead seals with characteristic spiral lesions have been washing ashore around the North Atlantic over the past two decades.Interactions with ship propellers and shark predation have been Windsock Pole Lights suggested as the likely causal mechanisms.However, new evidence points towards a more likely candidate: grey seal predation.A
BackgroundOrientia tsutsugamushi is a clinically important but neglected obligate intracellular bacterial pathogen of the Rickettsiaceae family that causes the potentially life-threatening human disease scrub typhus.In contrast to the genome reduction seen in many obligate intracellular bacteria, early genetic studies of Orientia have revealed one
Abstract This paper presents mechanical and electrical design, and implementation process of industrial robot, 3-DoF type SCARA (selective compliment assembly robot arm),with two rotations and one translation used for welding applications.The design process also included the controller design which was based on Magazine Rack PLC(programmable logic
