Special Presentation by Wassim Jabi, Quentin Jones, Katia
Special Presentation by Wassim Jabi, Quentin Jones, Katia Passerini, Cristian Borcea, and Theodore Hall, “Fostering Creativity in Ubiquitous Social Computing through Casual and Formal Interactions in Interdisciplinary Design Studios”, Tables 1 This project aims to foster "CreativeIT": using information technology to enhance creativity in design, and applying creative design processes employed in disciplines such as architecture to enhance information technology. One aspect of this project is an interactive touch-screen poster display that enables two-way communication between designers, other team members, and the general public. Poster authors prepare their presentations in the form of web pages and submit the URIs to the display manager. The URIs are placed in an XML poster database on a networked server. The display kiosk software updates its poster list from the XML file periodically, displays the posters in sequence, and places thumbnails in a selection area. Viewers can give feedback on any poster that interests them through graffiti-style interaction with the touch-sensitive display, and e-mail the marked-up poster back to the author. This free-form feedback is a vital part of the creative process. Ikemefuna Chukwuemeka Agbanusi, Senior Student in Mathematics, “Dissecting the Phase Response Curve of a Bursting Neuron”, (advised by Amitabha Bose, advisors Amitabha Bose, Farzan Nadim and Jorge Golowasch), Table 52 We define and analyze the Phase Response Curve (PRC) of an endogenous neuronal oscillator. The PRC measures how an oscillator responds to the timing of stimulus. We utilize a Morris-Leccar type model to reproduce some of the phenomena observed in laboratory experiments on the PD neuron in the Stomatogastric Ganglion of the crab, Cancer borealis. -
3.1 Discipline Science Results
CASSINI FINAL MISSION REPORT 2019 1 SATURN Before Cassini, scientists viewed Saturn’s unique features only from Earth and from a few spacecraft flybys. During more than a decade orbiting the gas giant, Cassini studied the composition and temperature of Saturn’s upper atmosphere as the seasons changed there. Cassini also provided up-close observations of Saturn’s exotic storms and jet streams, and heard Saturn’s lightning, which cannot be detected from Earth. The Grand Finale orbits provided valuable data for understanding Saturn’s interior structure and magnetic dynamo, in addition to providing insight into material falling into the atmosphere from parts of the rings. Cassini’s Saturn science objectives were overseen by the Saturn Working Group (SWG). This group consisted of the scientists on the mission interested in studying the planet itself and phenomena which influenced it. The Saturn Atmospheric Modeling Working Group (SAMWG) was formed to specifically characterize Saturn’s uppermost atmosphere (thermosphere) and its variation with time, define the shape of Saturn’s 100 mbar and 1 bar pressure levels, and determine when the Saturn safely eclipsed Cassini from the Sun. Its membership consisted of experts in studying Saturn’s upper atmosphere and members of the engineering team. 2 VOLUME 1: MISSION OVERVIEW & SCIENCE OBJECTIVES AND RESULTS CONTENTS SATURN ........................................................................................................................................................................... 1 Executive -

Chronophilia; Or, Biding Time in a Solar System
Chronophilia; or, Biding Time in a Solar System MARCUS HALL Department of Evolutionary Biology and Environmental Studies, University of Zurich, Switzerland Abstract Having evolved in a dynamic solar system, all life on earth has adapted to and de- pends on recurring and repeating cycles of light, heat, and gravity. Our sleep cycles, repro- ductive cycles, and emotional cycles are all linked in varying ways to planetary motion even though we continually disrupt, modify, or extend these cycles to go about our personal and collective business. This essay explores how our sense of time is both physiological and cul- tural, with deep ramifications for confronting such challenges as jet lag, navigation, calendar construction, shift work, and even life span. Although chronobiologists have posited the existence of a Zeitgeber, or external master clock that serves to reset our internal clocks, it hasbecomeclearthatanymasterclockreliesasmuchonnaturalelements(suchasarising sun) as cultural elements (such as an alarm clock). Moreover the “circa” of circadian rhythms, suggests that our activities and emotions recur, not in exact twenty-four-hour cycles, but in more plastic and approximate cycles that, according to circumstance and individual, may span somewhat longer or shorter periods than one earthly rotation. Or as one chronobiolo- gist explains, “Any one physiologic variable is characterized by a spectrum of rhythms that aregeneticallyanchored,sociologicallysynchronized...andinfluenced by heliogeophysical effects.” As we contemplate faster and further travel and other activities that disrupt our biorhythms, we need to develop greater awareness of chronophilia, our attachment to rhythm, our love of familiar time. Keywords chronobiology, biorhythm, circadian, desynchrony, jet lag, shift work, sense of time ven before the newborn infant takes his or her first gasps of air, he or she has settled E into recurring patterns of rest and activity. -

1 David Elijah Packer: cluster variables, meteors and the solar corona Jeremy Shears Abstract David Elijah Packer (1862-1936), a librarian by profession, was an enthusiastic amateur astronomer who observed from London and Birmingham. He first came to the attention of the astronomical community in 1890 when he discovered a variable star in the globular cluster M5, only the second periodic variable to be discovered in a globular cluster. He also observed meteors and nebulae, on one occasion reporting a brightening in the nucleus of the galaxy M77. However, his remarkable claims in 1896 that he had photographed the solar corona in daylight were soon shown to be flawed. Biographical sketch David Elijah Packer was born in Bermondsey, London, in 1862 April (1) the eldest child of Edward Packer (1820-1896) and Emma (Bidmead) Packer (1831-1918) (2). David attended the Free Grammar School of Saint Olave and Saint John at Southwark, where he performed well, especially in arithmetic, algebra and general mathematics (3). Edward Packer was a basket maker, as was his father and grandfather before him, the Packer family originally coming to London from Thanet, in Kent. The English basket-making industry was in decline during the second half of the nineteenth century due to the availability of cheaper imports from the continent. In spite of this, Edward was still in business in 1881, but the prospects for his son continuing in a trade that had made a living for generations of his ancestors were probably limited (4). Thus at the age of 18 we find David Elijah Packer working as an Oilman’s Assistant, supplying fuel for the oil lamps of London (5). -

NASA SP17069 NASA Thesaurus Astronomy Vocabulary Scientific and Technical Information Division 1988 National Aeronautics and Space Administration Washington, M= . ' NASA SP-7069 NASA Thesaurus Astronomy Vocabulary A subset of the NASA Thesaurus prepared for the international Astronomical Union Conference July 27-31,1988 This publication was prepared by the NASA Scientific and Technical Information Facility operated for the National Aeronautics and Space Administration by RMS Associates. INTRODUCTION The NASA Thesaurus Astronomy Vocabulary consists of terms used by NASA indexers as descriptors for astronomy-related documents. The terms are presented in a hierarchical format derived from the 1988 edition of the NASA Thesaurus Volume 1 -Hierarchical Listing. Main (postable) terms and non- postable cross references are listed in alphabetical order. READING THE HIERARCHY Each main term is followed by a display of its context within a hierarchy. USE references, UF (used for) references, and SN (scope notes) appear immediately below the main term, followed by GS (generic structure), the hierarchical display of term relationships. The hierarchy is headed by the broadest term within that hierarchy. Terms that are broader in meaning than the main term are listed . above the main term; terms narrower in meaning are listed below the main term. The term itself is in boldface for easy identification. Finally, a list of related terms (RT) from other hierarchies is provided. Within a hierarchy, the number of dots to the left of a term indicates its hierarchical level - the more dots, the lower the level (i.e., the narrower the meaning of the term). For example, the term "ELLIPTICAL GALAXIES" which is preceded by two dots is narrower in meaning than "GALAXIES"; this in turn is narrower than "CELESTIAL BODIES". -
Mars Weather and Predictability: Modeling and Ensemble Data Assimilation of Spacecraft Observations
ABSTRACT Title of Document: MARS WEATHER AND PREDICTABILITY: MODELING AND ENSEMBLE DATA ASSIMILATION OF SPACECRAFT OBSERVATIONS Steven J. Greybush, Ph.D., 2011 Directed By: Professor Eugenia Kalnay, Department of Atmospheric and Oceanic Science, The University of Maryland, College Park Combining the perspectives of spacecraft observations and the GFDL Mars General Circulation Model (MGCM) in the framework of ensemble data assimilation leads to an improved understanding of the weather and climate of Mars and its atmospheric predictability. The bred vector (BV) technique elucidates regions and seasons of instability in the MGCM, and a kinetic energy budget reveals their physical origins. Instabilities prominent in the late autumn through early spring seasons of each hemisphere along the polar temperature front result from baroclinic conversions from BV potential to BV kinetic energy, whereas barotropic conversions dominate along the westerly jets aloft. Low level tropics and the northern hemisphere summer are relatively stable. The bred vectors are linked to forecast ensemble spread in data assimilation and help explain the growth of forecast errors. Thermal Emission Spectrometer (TES) temperature profiles are assimilated into the MGCM using the Local Ensemble Transform Kalman Filter (LETKF) for a 30-sol evaluation period during the northern hemisphere autumn. Short term (0.25 sol) forecasts compared to independent observations show reduced error (3–4 K global RMSE) and bias compared to a free running model. Several enhanced techniques result in further performance gains. Spatially-varying adaptive inflation and varying the dust distribution among ensemble members improve estimates of analysis uncertainty through the ensemble spread, and empirical bias correction using time mean analysis increments help account for model biases.
