Ultrafast helicity control of surface currents in topological insulators with near-unity fidelity. [PDF]
Nat Commun, 2015 In recent years, a class of solid state materials, called three-dimensional topological insulators, has emerged. In the bulk, a topological insulator behaves like an ordinary insulator with a band gap.

North Atlantic Ocean surface currents [PDF]
Journal of Geophysical Research: Oceans, 2003 Close to 1800 surface drifters are used to investigate the 15 m circulation of the North Atlantic Ocean. The data are used to describe structures of the average Eulerian circulation and of the associated eddy variability. The data resolve scales on the order of 50 km, which have hitherto not been systematically described, in particular, near shelf ...

Design of Wideband Elliptical Ring Monopole Antenna Using Characteristic Mode Analysis [PDF]
Journal of Electromagnetic Engineering and Science, 2021 This paper presents the systematic design of an elliptical ring monopole wideband antenna using characteristic mode analysis. The modal analysis is used to analyze the bandwidth and the radiation performance of the radiating patch.

Earth and Space Science, 2023 The western Arctic marginal seas undergo large seasonal variation, but are very challenging to observe directly due to sea ice and shallow depths. Deployments of several saildrone uncrewed surface vehicles in the summers of 2018 and 2019 provided unique ...

Current developments in surface electromyography
Turkish Journal of Medical Sciences, 2023 Surface electromyography (surface EMG) is a primary technique to detect the electrical activities of muscles through surface electrodes. In recent years, surface EMG applications have grown from conventional fields into new fields. However, there is a gap between the progress in the research of surface EMG and its clinical acceptance, characterized by ...

Ka-Band Doppler Scatterometry over a Loop Current Eddy
Remote Sensing, 2020 Doppler scatterometry is a promising new technique for the simultaneous measurement of ocean surface currents and winds. These measurements have been recommended by the recent US NRC Decadal Review for NASA as being priority variables for the coming ...

Prevalence of Deformation‐Scale Surface Currents
Geophysical Research Letters, 2023 Understanding the transport of large ocean currents, like the Gulf Stream, has been of interest since the early days of oceanography. There has been less attention on the widths of the currents, although there exist several theoretical predictions.

Forecast uncertainty and ensemble spread in surface currents from a regional ocean model
Frontiers in Marine Science, 2023 An operational ocean Ensemble Prediction System (EPS) for the coastal seas off Northern Norway is evaluated by comparing with high-frequency radar current speed estimates. The EPS is composed of 24 members for which the ocean current is not perturbed nor
