Intensity-intensity correlations as a probe of interferences - under conditions of none in the intensity

The different behaviour of first order interferences and second order correlations are investigated for the case of two coherently excited atoms. For intensity measurements this problem is equivalent to Young's double slit experiment and was investigated in an experiment by Eichmann et al. [Phys. Rev. Lett. 70, 2359 (1993)] and later analyzed in detail by Itano et al. [Phys. Rev. A 57, 4176 (1998)]. Our results show that in cases where the intensity interferences disappear the intensity-intensity correlations can display an interference pattern with a visibility of up to 100%. The contrast depends on the polarization selected for the detection and is independent of the strength of the driving field. The nonclassical nature of the calculated intensity-intensity correlations is also discussed.Comment: 14 pages, 2 figure

Tell Me a Science Story: Transforming Engagement with Science Using Creative Nonfiction

“I definitely felt more engaged with the first one [creative nonfiction]and less tuned out because I had somebody interpreting their response for me. So when he was like “Oh, I was surprised” then I think “Oh, so was I, I was also surprised by the piece of information.” So I was more engaged with it personally even if I didn\u27t retain all the numbers... “ “[The story] seemed more relatable I guess, as a normal, average, everyday person than a whole bunch of scientists talking about facts. Where the facts were still in here, the way that it was written was more along a story line.

From Individual Wellbeing to Collective Welfare: A New Perspective of Being and Becoming in a Post-Pandemic World

This article gives an overview of the twice four-dimensional logic that underpins the POZE paradigm at the individual and collective level. It is based on the understanding that human existence is a composition of four dimensions—soul, heart, mind and body, expressed as aspirations, emotions, thoughts and sensations. This individual multidimensionality reflects the collective arena, which is composed of micro, meso, macro and meta dimensions, in the form of individuals, communities, countries and planet earth. Individual wellbeing is the cause and consequence of collective welfare, due to four principles that influence the individual and the collective sphere: change, connection, continuity and complementarity. One without the other is not sustainable. Aid must be designed and delivered with the ambition of holistic support that considers not only each dimension but contributes to the optimisation of their mutual interplay, the ultimate ambition being to lift individuals everywhere to fulfill their potential

Synodical Address-1848

(The 1848 Synodical Address of C. F. Walther, which is presented here in translation, clearly sets forth his views on the relationship between the congregations and The Lutheran Church-Missouri Synod. Dr. Walther\u27s views were repeated almost verbatim in a Brother to Brother (Mein theurer Herr Amtsbruder} letter of Jan. 12, 1875, in which he assured the congregations of their freedom to accept or reject synodical resolutions, and then pleaded with them to freely accept a synodical resolution that called for a building fund collection for new construction at three synodical schools

Public Opinions of Unmanned Aerial Technologies in 2014 to 2019: A Technical and Descriptive Report

The primary purpose of this report is to provide a descriptive and technical summary of the results from similar surveys administered in fall 2014 (n = 576), 2015 (n = 301), 2016 (ns = 1946 and 2089), and 2018 (n = 1050) and summer 2019 (n = 1300). In order to explore a variety of factors that may impact public perceptions of unmanned aerial technologies (UATs), we conducted survey experiments over time. These experiments randomly varied the terminology (drone, aerial robot, unmanned aerial vehicle (UAV), unmanned aerial system (UAS)) used to describe the technology, the purposes of the technology (for economic, environmental, or security goals), the actors (public or private) using the technology, the technology’s autonomy (fully autonomous, partially autonomous, no autonomy), and the framing (promotion or prevention) used to describe the technology’s purpose. Initially, samples were recruited through Amazon’s Mechanical Turk, required to be Americans, and paid a small amount for participation. In 2016 we also examined a nationally representative samples recruited from Qualtrics panels. After 2016 we only used nationally representative samples from Qualtrics. Major findings are reported along with details regarding the research methods and analyses

Study to establish cost projections for production of Redox chemicals

A cost study of four proposed manufacturing processes for redox chemicals for the NASA REDOX Energy Storage System yielded favorable selling prices in the range $0.99 to$1.91/kg of chromic chloride, anhydrous basis, including ferrous chloride. The prices corresponded to specific energy storage costs from under $9 to$17/kWh. A refined and expanded cost analysis of the most favored process yielded a price estimate corresponding to a storage cost of $11/kWh. The findings supported the potential economic viability of the NASA REDOX system
