purpose the aim of this study was to evaluate predictor variables of race time in female ultra-endurance inliners in the longest inline race in europe. methods we investigated the association between anthropometric and training characteristics and race time for 16 female ultra-endurance inline skaters, at the longest inline marathon in europe, the ‘inline one-eleven’ over 111 km in switzerland,...

We propose an on-chip spectrometer camera for sub-millimeter astronomy. The camera will be installed to the focal plane of a telescope and be operated at 0.1 K. The camera is composed of three kinds superconducting circuits, such as wideband antennas, band pass filters (BPFs), and Microwave Kinetic Inductance Detectors (MKID) [1]. All components are fabricated on the same chip by the standard p...

We have designed and constructed a custom far-infrared Fourier transform spectrometer using an antenna-coupled bolometer as a detector. The active element of the detector is a superconducting niobium microbridge, and the far-infrared signal is coupled to the microbridge via a planar antenna mounted on a hyperhemispherical silicon lens. The spectrometer uses a broadband blackbody source with fre...

The extremely small size of plasmonic antennas has made it difficult to integrate them with nanoscale detectors that require electrical leads, as the leads tend to degrade the resonant properties of the antenna. We present a design for integrating a plasmonic antenna with a nanoscale superconducting transition-edge sensor (TES) with electrical leads. Numerical simulations demonstrate high-effic...

In this paper, an Archimedean spiral antenna has been developed to flexibly radiate orbital angular momentum (OAM) wave with tunable modes. The operation mechanism for generation of the OAM is elaborated in terms phases currents flowing on arm structure. Two pairs feeding probes are introduced excite antenna. With signals different phase differences fed into antenna, waves modes <inline-formula...

In this letter, we present a planar half-Luneburg lens antenna based on glide-symmetric dielectric structure. The proposed provides compact alternative to beamformers such as conventional Luneburg and Rotman lenses, well pillbox antennas. Importantly, demonstrate that the peak gain of is less than 1 dB lower antenna, despite being almost half size. can steer its beam in 50 <inline-formula xmlns...
