Reading is a complex visuomotor behavior characterized by an alternation of fixations and saccadic eye movements. Despite the widespread use of drifting texts in various settings, very little is known about eye movements under these conditions. Here we investigated oculomotor behavior during reading of texts which were drifting horizontally or vertically at different speeds. Consistent with pre...

In this short note, we prove the convexity of the first eigenfunction of the drifting Laplacian operator with zero Dirichlet boundary value provided a suitable assumption to the drifting term is added. After giving a gradient estimate, we then use the convexity of the first eigenfunction to get a lower bound of the difference of the first and second eigenvalues of the drifting Laplacian.

The Doppler shift of a radio signal is caused by the relative motion between transmitter and receiver. change in frequency over time called drift rate. In studies SETI (Search for Extraterrestrial Intelligence), extraterrestrial narrowband signals are expected to appear "chirped" since both exoplanet Earth moving. Such planet rotation orbital revolution around central star can cause non-zero Ot...

We present the statistical results of a systematic, unbiased search for subpulse modulation of 187 pulsars performed with the Westerbork Synthesis Radio Telescope (WSRT) in the Netherlands at an observing wavelength of 21 cm (Weltevrede et al. 2006a). We have increased the list of pulsars that show the drifting subpulse phenomenon by 42, indicating that more than 55% of the pulsars that show th...

Abstract The LPMWPC can be used as the Δ E detector for low-energy charged particle detection. In order to increase transmittance, wires were adopted cathode. This work investigated signal characteristics of this configuration and measured gas gain with a mixture 90%Ar 10% CO2 from 1E3 1E5 Pa. From test, second pulse after avalanche was observed, which proved caused by ions' drifting near catho...

A new drifting pulsar, PSR J0815+09, was discovered in the Arecibo driftscan searches (McLaughlin et al. 2004). An intriguing feature of this source is that within the four pulse components in the integrated pulse profile, the subpulse drifting direction in the two leading components is opposite from that in the two trailing components. In view that the leading theoretical model (Ruderman & Sut...

This paper investigates the drifting problem in Progressive Fine Granularity Scalable (PFGS) video coding, which arises from the fact that high quality references are used to predict the enhancement layer. Due to the unique property of the PFGS scheme, this paper first analyzes the occurrence and propagation of the drifting errors in details. As a result, an iterative model is established to si...

Mode-locked fiber lasers are applied in versatile scientific fields and exhibit a rich diversity of nonlinear dynamics. However, the nontrivial coexistence solitons embedded dispersive wave radiation prevents unveiling real dynamics mode-locked lasers, such as multiple interaction. Here, Fourier transform (NFT) is signal processing tool to reveal nonequilibrium soliton It feasible isolate from ...
