We studied the drift of electron spins under an applied dc electric field in single layer graphene spin valves in a field-effect transport geometry at room temperature. In the metallic conduction regime (n approximately 3.5 x 10(16) m(-2)), for dc fields of about +/- 70 kV/m applied between the spin injector and spin detector, the spin valve signals are increased or decreased, depending on the ...

the main cause of structural damage in buildings subjected to seismic actions is lateral drift. in almost all reinforced concrete (rc) structures, whether designed with walls or frames, it is likely to be the code drift limits that control the design drift. the design drift limits and their contribution to damage may be represented indirectly through the material strain limits. the aim of this ...

Numerous third-generation light sources are now in a mature phase of operation, and several new sources are under construction. Submicron beam stability is being achieved routinely at many of these light sources in terms of both AC (rms 0.1 200 Hz) and DC (one week drift) motion. This level of stability is a necessary condition for the success of x-ray free-electron lasers such as the Linac Coh...

This paper describes a high-temperature pressure-transducer interface for resistive Wheatstone bridges. The long-term drift of the smart sensor, i.e., the (pressure) sensor plus its interface electronics, will be determined by the drift of the sensor element only. A three-signal auto-calibration sequence of the interface electronics keeps the transducer interface virtually free of long-term dri...

This work is devoted to the study of drift operating point integrated-optical circuits based on proton-exchange waveguides in lithium niobate crystal with a recovered structure near-surface layer. Recovered damaged layer wafer was carried out using pre-annealing at temperature 500 °C. Drift characterized by constant change optical output power when bias voltage applied electrodes or changes. le...

In the perceptual learning (PL) literature, researchers typically focus on improvements in accuracy, such as d'. In contrast, researchers who investigate the practice of cognitive skills focus on improvements in response times (RT). Here, we argue for the importance of accounting for both accuracy and RT in PL experiments, due to the phenomenon of speed-accuracy tradeoff (SAT): at a given level...

This paper describes an approach for the fusion of 3D data underwater obtained from multiple sensing modalities. In particular, we examine the combination of imagebased Structure-From-Motion (SFM) data with bathymetric data obtained using pencil-beam underwater sonar, in order to recover the shape of the seabed terrain. We also combine image-based egomotion estimation with acousticbased and ine...

Abstract. Throughout winter, the winds of migrating weather systems drive recurrent opening sea ice leads from Alaska's northernmost headland, Point Barrow. As extend offshore into Beaufort and Chukchi seas, they produce velocity discontinuities that are challenging to represent in models. We investigate how synoptic wind patterns form originating Barrow influence drift across Pacific Arctic. i...
