Citation Analysis for the Modern Instructor: an Integrated Review of Emerging Research
CITATION ANALYSIS FOR THE MODERN INSTRUCTOR: AN INTEGRATED REVIEW OF EMERGING RESEARCH Chris Piotrowski University of West Florida USA Abstract While online instructors may be versed in conducting e-Research (Hung, 2012; Thelwall, 2009), today’s faculty are probably less familiarized with the rapidly advancing fields of bibliometrics and informetrics. One key feature of research in these areas is Citation Analysis, a rather intricate operational feature available in modern indexes such as Web of Science, Scopus, Google Scholar, and PsycINFO. This paper reviews the recent extant research on bibliometrics within the context of citation analysis. Particular focus is on empirical studies, review essays, and critical commentaries on citation-based metrics across interdisciplinary academic areas. Research that relates to the interface between citation analysis and applications in higher education is discussed. Some of the attributes and limitations of citation operations of contemporary databases that offer citation searching or cited reference data are presented. This review concludes that: a) citation-based results can vary largely and contingent on academic discipline or specialty area, b) databases, that offer citation options, rely on idiosyncratic methods, coverage, and transparency of functions, c) despite initial concerns, research from open access journals is being cited in traditional periodicals, and d) the field of bibliometrics is rather perplex with regard to functionality and research is advancing at an exponential pace. Based on these findings, online instructors would be well served to stay abreast of developments in the field. Keywords: Bibliometrics, informetrics, citation analysis, information technology, Open resource and electronic journals INTRODUCTION In an ever increasing manner, the educational field is irreparably linked to advances in information technology (Plomp, 2013). -
CERN Bulletin
CERN Bulletin Nos 41 & 42 – 12 & 19 October 2011 Upstream from OPERA: extreme Science driving facilities for attention to detail particle physics his week, CERN played host to the T10th ICFA (International Commit- tee for Future Accelerators) seminar, which brought together some 200 scientists, government agency rep- resentatives and lab directors from around the world to take the pulse of our field. ICFA seminars take place every three years, and this time the emphasis was on science as the driv- ing force for facilities. The theme of this year’s seminar could not have been more timely.

Photons That Travel in Free Space Slower Than the Speed of Light Authors
Title: Photons that travel in free space slower than the speed of light Authors: Daniel Giovannini1†, Jacquiline Romero1†, Václav Potoček1, Gergely Ferenczi1, Fiona Speirits1, Stephen M.

However, light beams have finite transverse size, which leads to a modification of their wavevectors resulting in a change to their phase and group velocities. We study the group velocity of single photons by measuring a change in their arrival time that results from changing the beam’s transverse spatial structure. Using time-correlated photon pairs we show a reduction of the group velocity of photons in both a Bessel beam and photons in a focused Gaussian beam. In both cases, the delay is several microns over a propagation distance of the order of 1 m. Our work highlights that, even in free space, the invariance of the speed of light only applies to plane waves. Introducing spatial structure to an optical beam, even for a single photon, reduces the group velocity of the light by a readily measurable amount. One sentence summary: The group velocity of light in free space is reduced by controlling the transverse spatial structure of the light beam. Main text The speed of light is trivially given as �/�, where � is the speed of light in free space and � is the refractive index of the medium. -

Padgett2, y 1Department of Opto-electronic Engineering, Beihang University, Beijing, 100191, China 2SUPA, School of Physics and Astronomy, University of Glasgow, Glasgow, G12 8QQ, UK 3Selex ES, Edinburgh, UK Time-of-flight three dimensional imaging is an important tool for many applications, such as object recognition and remote sensing. Unlike conventional imaging approach using pixelated detector array, single-pixel imaging based on projected patterns, such as Hadamard patterns, utilises an alternative strategy to acquire information with sampling basis. Here we show a modified single-pixel camera using a pulsed illumi- nation source and a high-speed photodiode, capable of reconstructing 128×128 pixel resolution 3D scenes to an accuracy of ∼ 3 mm at a range of ∼ 5 m. Furthermore, we demonstrate continuous real-time 3D video with a frame-rate up to 12 Hz. The sim- plicity of the system hardware could enable low-cost 3D imaging devices for precision ranging at wavelengths beyond the visible spectrum. Introduction Whilst a variety of 3D imaging technologies are suited for different applications, time-of-flight (TOF) systems have set the benchmark for performance with regards to a combination of accuracy and operating range. Time-of-flight imaging is performed by illuminating a scene with a pulsed light source and observing the back-scattered light. Correlating the detection time of the back-scattered light with the time of the illumination pulse allows the distance, d, to objects within the scene to be estimated by d = tc=2, where t is the TOF and c is the propagation speed of light. -

Lenses Can Bend Light and Sound in Almost Any Direction 2 April 2012, by Lisa Zyga
Lenses can bend light and sound in almost any direction 2 April 2012, by Lisa Zyga a change, or gradient, in the refractive index of a lens, the scientists could create anisotropies - that is, make the lens' refractive index directionally dependent. "We explain how one can either focus or bend (at 90°, 180° and 360°) electromagnetic or pressure waves simply by creating some gradient of the refractive index, which in essence is associated with effective anisotropy," Guenneau told PhysOrg.com.

Amplification of waves from a rotating body Marion Cromb,1 Graham M. Gibson,1 Ermes Toninelli,1 Miles J. Padgett,1, ∗ Ewan M. Wright,2 and Daniele Faccio1, 2, y 1School of Physics and Astronomy, University of Glasgow, Glasgow, G12 8QQ, UK 2College of Optical Sciences, University of Arizona, Tucson, Arizona 85721, USA (Dated: May 11, 2020) In 1971 Zel'dovich predicted that quantum fluctuations and classical waves reflected from a ro- tating absorbing cylinder will gain energy and be amplified. This key conceptual step towards the understanding that black holes may also amplify quantum fluctuations, has not been verified ex- perimentally due to the challenging experimental requirements on the cylinder rotation rate that must be larger than the incoming wave frequency. Here we experimentally demonstrate that these conditions can be satisfied with acoustic waves. We show that low-frequency acoustic modes with orbital angular momentum are transmitted through an absorbing rotating disk and amplified by up to 30% or more when the disk rotation rate satisfies the Zel'dovich condition. These experiments address an outstanding problem in fundamental physics and have implications for future research into the extraction of energy from rotating systems. Introduction. In 1969, Roger Penrose proposed a an amplifier. Outgoing waves then have an increased am- method to extract the rotational energy of a rotating plitude, therefore extracting energy from the rotational black hole, now known as Penrose superradiance [1]. Pen- energy of the body in the same spirit of Penrose's pro- rose suggested that an advanced civilisation might one posal. day be able to extract energy from a rotating black hole Satisfying the condition in Eq. -
