The redundant signals effect (RSE) refers to the fact that subjects generally respond faster to simultaneously presented redundant targets than to single targets in a detection task where they are required to monitor two or more information sources. Based on the notion of an activation state representation, a unifying formal framework for the various response time models developed for the RSE i...

A vector …eld in n-space is reconstructed from a n-dimensional family of ray or line integrals. A similar problem is considered for di¤erential forms of higher order. Key words: Di¤erential form, ray integral, k-plane integral, reconstruction, support condition AMS subject classi…cation (2000): Primary, 53C65; Secondary, 65R32, 76M27 Abbreviated title: Doppler transform 1 Introduction Integrals...

We study Doppler effects in curved space-time, i.e. the frequency shifts induced on electromagnetic signals propagating in the gravitational field. In particular, we focus on the frequency shift due to the bending of light rays in weak gravitational fields. We consider, using the PPN formalism, the gravitational field of an axially symmetric distribution of mass. The zeroth order, i.e. the sphe...

The vast majority of known extrasolar planets orbit stars with a narrow range of masses (0.7–1.3 M⊙). Little is known about the properties of planetary systems with host stars significantly more massive than the Sun. Planet formation models predict that giant planets are more common around higher-mass stars (M∗ > 1.5M⊙). However, these types of stars pose severe observational challenges while o...

REPORTS have been highly contradictory with respect to the possible development of increased anti-enzymic activity in the serum of a subject which has received repeated injections of a given enzyme preparation. Wells [1925], in reviewing the subject, considers the general thesis very much open to doubt. Probably the most definite evidence of a positive nature is the work by Kirk and Sumner [193...

II We have developed laser sources ofsodium-resonance radiation based on the sumfrequency mixing ofNd:YAG laser radiation. The sources are suitable for generating a fluorescence spot in the earth's mesospheric sodium layer for use in adaptive optics compensation. Taking into account the sodium fluorescence lifetime, Doppler broadening, hyperfine structUre, radiative saturation, optical pumping,...

This text describes the implementation of Ambisonics as user defined opcodes (UDOs) for Csound. The presented package of UDOs includes a basic encoder and a decoder up to 8th order, an encoder with distance correction, an in-phase decoder, opcodes for the two-dimensional equivalent of Ambisonics for any order, opcodes for Ambisonics equivalent panning (AEP) and several utilities such as coordin...

Online platforms are prone to abuse and manipulation from strategic parties. For example, social media and review websites suffer from the presence of opinion spam and fake reviews. Applying the economic concept of rational expectation equilibrium (REE), we explore the impact of manipulation on consumer welfare in a Twitter-like environment. We argue that the REE outcome can be decomposed into ...

Apart from regular monitoring by ASM, the compact object SS 433 was observed with RXTE several times last two/three years. We present the first analysis of these observations. We also include the results of the recent exciting TOO campaign made during donour inferior (orbital phase φ = 0) and superior (φ = 0.5) conjunctions which took place on Oct. 2nd, 2003, and on March 13th, 2004 respectivel...
