description: Synchronisation between coupled oscillatory systems is a common phenomenon in many natural as well as technical systems. Varying the strength of coupling often leads to qualitative changes in the complex dynamics of the mutually coupled systems including different types of synchronisation such as phase, lag, generalised, or even complete synchronisation. Here, we study the geometric signatures of coupling along with the onset of generalised synchronisation between two coupled chaotic oscillators by mapping the systems' individual as well as joint recurrences in phase space to a complex network. For a paradigmatic continuous-time model system, the transitivity properties of the resulting joint recurrence networks display distinct variations associated with changes in the structural similarity between different parts of the considered trajectories. They therefore provide a useful indicator for the emergence of generalised synchronisation. This paper is dedicated to the 25th anniversary of the introduction of recurrence plots by Eckmann et al. (Europhys. Lett. 4 (1987), 973).

description: We study the hybrid quantization of the linearly polarized Gowdy $T^3$ model with a massless scalar field with the same symmetries as the metric. For simplicity, we quantize its restriction to the model with local rotational symmetry. Using this hybrid approach, the homogeneous degrees of freedom of the geometry are quantized à la loop, leading to the resolution of the cosmological singularity. A Fock quantization is employed both for the matter and the gravitational inhomogeneities. Owing to the inclusion of the massless scalar field this system allows us to modelize flat Friedmann-Robertson-Walker cosmologies filled with inhomogeneities propagating in one direction, providing a perfect scenario to study the quantum back-reaction of the inhomogeneities on the polymeric homogeneous and isotropic background.

description: We analyze the transport of heat along a chain of particles interacting through anharmonic po- tentials consisting of quartic terms in addition to harmonic quadratic terms and subject to heat reservoirs at its ends. Each particle is also subject to an impulsive shot noise with exponentially distributed waiting times whose effect is to change the sign of its velocity, thus conserving the en- ergy of the chain. We show that the introduction of this energy conserving stochastic noise leads to Fourier law. The behavior of thels heat conductivity for small intensities of the shot noise and large system sizes are found to obey a finite-size scaling relation. We also show that the heat conductivity is not constant but is an increasing monotonic function of temperature.
title: Color Woodblock Prints, an Exhibition by Linda Mahoney '79

description: The UMass Amherst Libraries host Color Woodblock Prints, an Exhibition by Linda Mahoney ’79, from January 23 through April 28, 2017, in the Science & Engineering Library (SEL), Lederle Graduate Research Center Lowrise, at the University of Massachusetts Amherst.

Linda Mahoney has been a painter for over 30 years. She lives in Northfield, Massachusetts, and was an art teacher at Stoneleigh-Burnham School for Girls in Greenfield, Massachusetts, from 1987 to 2016. In 2007, she took a workshop in Moku Hanga—Japanese watercolor woodblock printmaking—and fell in love with all parts of the process. It has become her primary medium.

Mahoney graduated from UMass Amherst in 1979 with a B.F.A. in Painting and a minor in Art History. Her artworks have been exhibited locally, nationally, and internationally through the Art in Embassies Program which promotes the cultural identity of America’s art and artists by borrowing original works of art by U.S. citizens for display in approximately 180 U.S. embassy residences worldwide.

During the last five years she has been exhibiting her color woodblock prints in outdoor art shows throughout New England, and has received several awards for her prints. In June of 2016, she was the “Artist in Residence” at Acadia National Park in Maine.

Moku Hanga consists of designing an image, carving several blocks for each print design, experimenting with colors while proof printing, refining the blocks and colors, using brushes to apply water-based paint mixed with rice paste to the paper and then applying pressure with a hand-held baren (a pad of twisted cord covered with paper, cloth, and bamboo leaves) in order to make the final print.

“I paint numerous watercolors en plein air, during the warmer months, returning to favorite places each year. I favor the undisturbed landscape, usually nature preserves, state parks, wildlife sanctuaries, or undeveloped coastal areas,” says Mahoney. “I am particularly drawn to Downeast Maine; the Schoodic Peninsula, Steuben, Addison, and Lubec. Distinctive trees, crashing surf and rocks, bogs, boreal forests, marshes, and active skies are frequently my subjects.”

Mahoney then studies these watercolors and selects the ones that best capture the spirit of place to use as designs for her color woodblock prints.

The exhibition will include a display of her materials and process.

description: Evidence in the Solar System suggests that the giant planets underwent an epoch of radial migration that was very rapid, with an e-folding timescale shorter than 1~Myr. It is probable that the cause of this migration was that the giant planets experienced an orbital instability that caused them to encounter each other, resulting in radial migration. Several works suggest that this dynamical instability occurred `late', long after all the planets had formed and the solar nebula had dissipated. Assuming that the terrestrial planets had already formed, then their orbits would have been affected by the migration of the giant planets. As a result, how did the orbits of the terrestrial planets change? And can we use this migration to obtain information on the primordial orbits of the terrestrial planets? We directly model a large number of terrestrial planet systems and their response to giant planet migration. We study the change in the Angular Momentum Deficit (AMD) of the terrstrials. We conclude that the primordial AMD should have been lower than ~70\% of the current value, but higher than 10\%. We find that a scenario with five giant planets better satisfies the orbital constraints of the terrestrial planets. We predict that Mars was initially on an eccentric and inclined orbit while the orbits of Mercury, Venus and Earth were more circular and coplanar. The lower primordial dynamical excitement and the peculiar partitioning between planets impose new constraints for terrestrial planet formation simulations.

description: We propose to use an optical cavity to enhance the sensitivity of magnetometers relying on the detection of the spin state of high-density nitrogen-vacancy ensembles in diamond using infrared optical absorption. The role of the cavity is to obtain a contrast in the absorption-detected magnetic resonance approaching unity at room temperature. We project an increase in the photon shot-noise limited sensitivity of two orders of magnitude in comparison with a single-pass approach. Optical losses can limit the enhancement to one order of magnitude which could still enable room temperature operation. Finally, the optical cavity also allows to use smaller pumping power when it is designed to be resonant at both the pump and the signal wavelength.

description: A tribological system consisting of two contacting blocks has been considered. One of them is arranged between two springs, the other is driven periodically. The kinetics of the system has been studied in the boundary friction mode, when an ultrathin lubricant film is contained between the atomically smooth surfaces. In order to describe the film state, the expression for the free energy density is used in the form of an expansion in a power series in the order parameter, the latter being reduced to the shear modulus of a lubricant. The stick-slip mode is shown to be realized in a wide range of parameters, being a result of the periodic first-order phase transitions between kinetic friction regimes. The behavior of the system governed by internal and external parameters has been predicted.

Der Fokus der Projektarbeiten lag auf zwei miteinander verbundene Monitoringaspekte, die laut einschlägigen Handlungsempfehlungen im Kontext von Open-Access-Transformationsverträgen mit kommerziellen Verlagen zwar wesentlich sind, auf die an den Einrichtungen jedoch häufig zugunsten institutioneller Publikations- und Kostenanalysen verzichtet wird: die Bemessung des Open-Access-Anteils wissenschaftlicher Artikel bezogen auf ein Verlagsportfolio mit hybriden Journalen und die Überprüfung verlagsseitiger Publikationsmetadaten hinsichtlich Vollständigkeit und Qualität. Die Besonderheit des Vorhabens ist es, dass ausschließlich offene Daten verwendet werden, um der wachsenden Bedeutung offener Metadaten beim Monitoring des Open Access Rechnung zu tragen. So stammen die Daten für ein vergleichendes Monitoring der nationalen Open-Access-Transformationsverträge, welches im Vortrag vorgestellt werden wird, aus den Quellen Crossref, OpenAlex, Unpaywall und des Open Access Monitor des FZ Jülich. Aufbereitet als quelloffenes Dashboard ermöglichen sie die vergleichende Analyse der hybriden Journalportfolios bezüglich ihres Open-Access-Anteils, der länderspezifischen Affiliation ihrer Autor*inInnen und ihrer Metadatenabdeckung. Mit dem Werkzeug metacheck entstand zudem ein Self-Assessment-Tool zur automatischen Gewinnung und Bewertung von Verlagsmetadaten bezogen auf Open-Access-Artikel in Crossref zur freien Nutzung.
On the estimation of normal copula discrete regression models using the continuous extension and simulated likelihood

Year: 2013
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: The continuous extension of a discrete random variable is amongst the computational methods used for estimation of multivariate normal copula-based models with discrete margins. Its advantage is that the likelihood can be derived conveniently under the theory for copula models with continuous margins, but there has not been a clear analysis of the adequacy of this method. We investigate the asymptotic and small-sample efficiency of two variants of the method for estimating the multivariate normal copula with univariate binary, Poisson, and negative binomial regressions, and show that they lead to biased estimates for the latent correlations, and the univariate marginal parameters that are not regression coefficients. We implement a maximum simulated likelihood method, which is based on evaluating the multidimensional integrals of the likelihood with randomized quasi Monte Carlo methods. Asymptotic and small-sample efficiency calculations show that our method is nearly as efficient as maximum likelihood for fully specified multivariate normal copula-based models. An illustrative example is given to show the use of our simulated likelihood method.

Chaos in large-amplitude pulsators: application to the beta Cep star HD180642
Creators: name: Degroote, Pieter
Publisher: name: arXiv
Year: 2013
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The CoRoT observations of the beta Cephei star HD180642 uncover an unexpectedly rich frequency spectrum, in addition to several heat-driven modes. So far, two processes have been proposed to explain this behaviour: the presence of stochastic oscillations, and the excitation of time-dependent frequencies by nonlinear resonance. I argue for a third explanation for the observations, in the form of chaos due to the nonlinear behaviour of the dominant radial mode. The long-term frequency stability of the dominant radial mode is studied using archival data spanning roughly 20 years. Nonlinear time series analysis techniques are applied to the CoRoT observations, and the observations are compared with simulations of a simple nonlinear oscillator. I show that chaos offers one single explanation for many of the observed features, such as the structure in the autocorrelation of the power spectrum, the long-term frequency shift, the power excess and the wide range of frequencies in the power spectrum. However, the mixture of opacity-driven linear oscillations and nonlinear oscillations complicate the nonlinear time series analysis techniques.

description: Ausgehend von dem Phänomen der Namengebung, das sämtlichen Kulturen der Welt eigen ist, versuchen die Autoren ein Bild des Zeitgeistes der aktuellen afghanischen Gesellschaft zu zeichnen. Personennamen spiegeln dies in besonderem Maße wider, so die Ausgangsthese der Autoren. Ausgehend von einer historischen Perspektive, die den Wandel im Bereich dieses speziellen Phänomens deutlich werden lässt, kann gezeigt werden, dass sich die heutige Namengebung und damit die Gesellschaft des Landes in einer weiteren Umbruchphase befindet. Anthroponyme müssen zurzeit besondere Beachtung finden, weil in den ländlich geprägten Gebiete des Landes Beinamen (= Familiennamen) bis heute völlig unüblich sind, rezent aber im Zuge des Aufbaus zentraler administrativer Strukturen gefordert werden. Gezeigt wird, welcher sprachlicher Mittel und Quellen sich bedient wird, um hierbei den neuerdings staatlicherseits gestellten Anforderung nachzukommen. Dies bringt in Unkenntnis der Sprachgeschichte und insbesondere der arabischen Sprachen vordergründig manch gewagtes Namenkonstrukt hervor. Dennoch reflektiert die Kreativität auf diesem Feld Trends allgemeiner Art, so dass afghanische Personennamen, Ruf- und Beinamen, als Träger ideologischer, ethnischer wie regionaler Vorgaben ins Blickfeld treten. Es ist dies der einleitende Teil, weitere Teile folgen in späteren Ausgaben dieser Zeitschrift. مولفان می‌کوشند با نگاه به پدیده‌ی نام‌گذاری، تصویری از روح جامعه‌ی افغانستانی معاصر رسم کنند. اصل موضوعه‌ی مقاله این است که نام‌های خاص به وجه احسن این تصویر را به دست می‌دهند. مبتنی بر دید تاریخی می توان دید که نام گذاری امروزی افغانستانی، همچنان که جامعه‌ی امروزی افغانستان، در آستانه تحولی قرار دارد. نام‌شناسی انسانی (آنتروپونوم) در حال حاضر ارزش خاصی از آن جهت می‌یابد، که در جوامع روستایی افغانستان، نام خانوادگی تا امروز غیر ساری بوده، اینک اما در جریانِ پی‌ریزی ساختار مدیریتی مرکزی، پشتیبانی شده و تداول می‌یابد. در این مقاله نشان داده می‌شود، کدام منابع و ابزارهای زبانی به خدمت گرفته می‌شوند، تا شروط مفروض حکومتی احراز شوند. ناآشنایی با تاریخِ زبان و به‌ویژه ناآشنایی با زبان عربی، موجب ساخته شدن نام‌های غیرمتعارفی می‌شود. این نام‌گذاری‌ها در عین حال خلاقیت در سلیقه‌های مختلف را بازتاب می‌دهند، چنان که می‌توان نام‌ها، نام‌های خانوادگی و شهرت‌های افغانستانی را محملی برای ایدئولوژی، تبارشناسی و داده‌های محلی در نظر گرفت. این نوشته بخش نخست این مقاله است. بخش های تالی در شماره های آینده ی این مجله چاپ خواهند شد.

description: Empirical research can generate large amounts of data for analysis. This data is the essential object of research and should be archived in a safe and well-documented way to keep it reusable for further research. Central criteria to realize this goal are outlined in the FAIR data guidelines. This bachelor's thesis investigates where and how many data publications are generated at selected research centers of the Helmholtz Association in Germany and to what extent these data publications adhere to the FAIR data guidelines. For this purpose, a data harvesting toolbox was further developed, that collects metadata of literature publications and associated data publications, published at these Helmholtz centers in the years from 2017 to 2022. The results are gathered and visualized in an interactive pilot dashboard. A first analysis of the data collected for Helmholtz-Zentrum Berlin shows that research data is published in different repositories and meets the FAIR data criteria to a variable degree. The dashboard provides a statistical overview of available data publications that originate from the research centers harvested. The number of data publications and statistical analyses of FAIR scores can be interactively explored. The project provides quantitative data, based on which HMC Hub Matter can identify key actions for engaging with repository infrastructure and research communities. In future work, the project can be extended to further research centers and provide a statistical overview of an even broader research community.

description: Energetic feedback from Supernovae and stellar winds can drive galactic winds. Dwarf galaxies, due to their shallower potential wells, are assumed to be more vulnerable to this phenomenon. Metal loss through galactic winds is also commonly invoked to explain the low metal content of dwarf galaxies. Our main aim in this paper is to show that galactic mass cannot be the only parameter determining the fraction of metals lost by a galaxy. In particular, the distribution of gas must play an equally important role. We perform 2-D chemo-dynamical simulations of galaxies characterized by different gas distributions, masses and gas fractions. The gas distribution can change the fraction of lost metals through galactic winds by up to one order of magnitude. In particular, disk-like galaxies tend to loose metals more easily than roundish ones. Consequently, also the final metallicities attained by models with the same mass but with different gas distributions can vary by up to one dex. Confirming previous studies, we also show that the fate of gas and freshly produced metals strongly depends on the mass of the galaxy. Smaller galaxies (with shallower potential wells) more easily develop large-scale outflows, therefore the fraction of lost metals tends to be higher.

title: ¡Hola Cuba! – Travel Photography by Carol Pike
Creators: name: University of Massachusetts Amherst Libraries
Publisher: name: University of Massachusetts Amherst

description: The UMass Amherst Libraries host an exhibition of photos, “¡Hola Cuba!: Travel Photography by Carol Pike,” from September 5 through December 15, 2017, in the Science & Engineering Library (SEL), at the University of Massachusetts Amherst. A reception will be held on Friday, September 22, from 2-4 p.m. The reception and exhibit are free and open to the public.

Retired teachers Carol Pike and Martha Tenney traveled to central Cuba in May 2016 with a “people-to-people” tour group through the Grand Circle Foundation. The photographs in the exhibit document their journey from Camagüey to Havana. Along the way, they met people from all walks of life, learning about their culture, history and everyday concerns.

“My hope is that the photographs I selected for this exhibit provide an introduction to the warm and resourceful Cuban people, a look at their colorful and vibrant culture, and a glimpse of some of the challenges they face,” said Pike.

Pike’s interest in photography began in 2003 when she bought her first digital camera. After taking several photography classes, she started submitting her work to the Daily Hampshire Gazette’s Valley Views column as well as group exhibits at the Robert Floyd Gallery in Southampton, Mass. and Green Trees Gallery in Northfield, Mass. Pike has also created four solo exhibits at the Dickinson Memorial Library in Northfield; her most recent, A Portrait of Cuba, was the basis for her current exhibit at UMass. Initially interested in capturing nature, her focus has shifted to photographing her travels. In addition to Cuba, she has recently traveled to Turkey, and the Netherlands. Next year, she and Tenney plan to visit Tanzania.

Pike, a retired math educator, is a resident of Northfield, Mass.

description: Recent advances in non-equilibrium statistical mechanics and single molecule technologies make it possible to extract free energy differences from irreversible work measurements in pulling experiments. To date, free energy recovery has been focused on native or equilibrium molecular states, whereas free energy measurements of kinetic states (i.e. finite lifetime states that are generated dynamically and are metastable) have remained unexplored. Kinetic states can play an important role in various domains of physics, such as nanotechnology or condensed matter physics. In biophysics, there are many examples where they determine the fate of molecular reactions: protein and peptide-nucleic acid binding, specific cation binding, antigen-antibody interactions, transient states in enzymatic reactions or the formation of transient intermediates and non-native structures in molecular folders. Here we demonstrate that it is possible to obtain free energies of kinetic states by applying extended fluctuation relations. This is shown by using optical tweezers to mechanically unfold and refold DNA structures exhibiting intermediate and misfolded kinetic states.

description: The peaks of 30 optical afterglows and 14 X-ray light-curves display a good anticorrelation of the peak flux with the peak epoch: F_p ~ t_p^{-2.0} in the optical, F_p ~ t_p^{-1.6} in the X-ray, the distributions of the peak epochs being consistent with each other. We investigate the ability of two forward-shock models for afterglow light-curve peaks -- an observer location outside the initial jet aperture and the onset of the forward-shock deceleration -- to account for those peak correlations. For both models, the slope of the F_p - t_p relation depends only on the slope of the afterglow spectrum. We find that only a conical jet seen off-aperture and interacting with a wind-like medium can account for both the X-ray peak relation, given the average X-ray spectral slope beta_x = 1.0, and for the larger slope of the optical peak relation. However, any conclusion about the origin of the peak flux - peak epoch correlation is, at best, tentative, because the current sample of X-ray peaks is too small to allow a reliable measurement of the F_p - t_p relation slope and because more than one mechanism and/or one afterglow parameter may be driving that correlation.

description: Motivated by the potential chiral spin liquid in the metallic spin ice Pr2Ir2O7, we consider how such a chiral state might be selected from the spin ice manifold. We propose that chiral fluctuations of the conducting Ir moments promote ferro-chiral couplings between the local Pr moments, as a chiral analogue of the magnetic RKKY effect. Pr2Ir2O7 provides an ideal setting to explore such a chiral RKKY effect, given the inherent chirality of the spin-ice manifold. We use a slave-rotor calculation on the pyrochlore lattice to estimate the sign and magnitude of the chiral coupling, and find it can easily explain the 1.5K transition to a ferro-chiral state.

description: Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared (HIFI), we have performed mapping observations of the 620.701 GHz 5(32)-4(41) transition of ortho-H2O within a roughly 1.5 x 1.5 arcmin region encompassing the Kleinmann-Low nebula in Orion, and pointed observations of that transition toward the Orion South condensation and the W49N region of high-mass star formation. Using the Effelsberg 100 m radio telescope, we obtained ancillary observations of the 22.23508 GHz 6(16)-5(23) water maser transition; in the case of Orion-KL, the 621 GHz and 22 GHz observations were carried out within 10 days of each other. The 621 GHz water line emission shows clear evidence for strong maser amplication in all three sources, exhibiting narrow (roughly 1 km/s FWHM) emission features that are coincident (kinematically and/or spatially) with observed 22 GHz features. Moreover, in the case of W49N - for which observations were available at three epochs spanning a two year period - the spectra exhibited variability. The observed 621 GHz/22 GHz line ratios are consistent with a maser pumping model in which the population inversions arise from the combined effects of collisional excitation and spontaneous radiative decay, and the inferred physical conditions can plausibly arise in gas heated by either dissociative or non-dissociative shocks. The collisional excitation model also predicts that the 22 GHz population inversion will be quenched at higher densities than that of the 621 GHz transition, providing a natural explanation for the observational fact that 22 GHz maser emission appears to be a necessary but insufficient condition for 621 GHz maser emission.

description: To date, the CoRoT space mission has produced more than 124,471 light curves. Classifying these curves in terms of unambiguous variability behavior is mandatory for obtaining an unbiased statistical view on their controlling root-causes. The present study provides an overview of semi-sinusoidal light curves observed by the CoRoT exo-field CCDs. We selected a sample of 4,206 light curves presenting well-defined semi-sinusoidal signatures. The variability periods were computed based on Lomb-Scargle periodograms, harmonic fits, and visual inspection. Color-period diagrams for the present sample show the trend of an increase of the variability periods as long as the stars evolve. This evolutionary behavior is also noticed when comparing the period distribution in the Galactic center and anti-center directions. These aspects indicate a compatibility with stellar rotation, although more information is needed to confirm their root-causes. Considering this possibility, we identified a subset of three Sun-like candidates by their photometric period. Finally, the variability period versus color diagram behavior was found to be highly dependent on the reddening correction.

title: Locus Solus: Place, meaning, and community in the life of Brother David Steindl-Rast
Creators: name: University of Massachusetts Amherst Libraries
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Exhibit “Locus Solus: Place, Meaning, and Community in the Life of Brother David Steindl-Rast,” showcases items curated from Steindl-Rast’s recent donation of correspondence, photographs, writings, audio/visual recordings, art, and publications. The Brother David Steindl-Rast Papers join a number of other recent high-profile donations to the Social Change Archive in Special Collections and University Archives, including the records of the New England Yearly Meeting (of Quakers), the Peter Simon Collection and the Bernard Jaffe Papers.

Steindl-Rast is one of the most important figures in the modern interfaith dialogue movement. Leaving his monastery in Elmira, New York, in the mid-1960s and receiving rare Vatican support for his bridge-building work between Christianity and Buddhism in 1967, Steindl-Rast became the first Benedictine to learn directly from Buddhist teachers such as Hakuun Yasutami, the founder of the Sanbo Kyodan Zen Buddhist organization; Soto Zen monk Shunayu Suzuki; and Zen Buddhist Master Soen Nakagawa.

Through his friend Thomas Merton, a Catholic writer, mystic, Trappist monk, and social activist, Steindl-Rast allied with Vietnamese Buddhist monk and peace activist Thich Nhat Hahn, to fight for peace. When not in seclusion, Steindl-Rast has served as a teacher of contemplative prayer, the intersection of Zen and Catholicism, and gratefulness as a spiritual practice. Steindl-Rast has developed an influential philosophy which he has disseminated through many books, articles, lectures, and residencies in spiritual centers such as Tassajara Zen Mountain Center—the first Buddhist monastery outside Asia—and the Esalen Institute, a retreat center and intentional community in Big Sur, California. Much of the current popularity of mindfulness and Zen-influenced living and activism owes a debt to his teachings.
Equivalence Principle Violation in Weakly Vainshtein-Screened Systems

description: Massive gravity, galileon and braneworld models that modify gravity to explain cosmic acceleration utilize the nonlinear field interactions of the Vainshtein mechanism to screen fifth forces in high density regimes. These source-dependent interactions cause apparent equivalence principle violations. In the weakly-screened regime violations can be especially prominent since the fifth forces are at near full strength. Since they can also be calculated perturbatively, we derive analytic solutions for illustrative cases: the motion of massive objects in compensated shells and voids and infall toward halos that are spherically symmetric. Using numerical techniques we show that these solutions are valid until the characteristic scale becomes comparable to the Vainshtein radius. We find a relative acceleration of more massive objects toward the center of a void and a reduction of the infall acceleration that increases with the mass ratio of the halos which can in principle be used to test the Vainshtein screening mechanism.

Death and resurrection of the zeroth principle of thermodynamics

description: The zeroth principle of thermodynamics in the form "temperature is uniform at equilibrium" is notoriously violated in relativistic gravity. Temperature uniformity is often derived from the maximization of the total number of microstates of two interacting systems under energy exchanges. Here we discuss a generalized version of this derivation, based on informational notions, which remains valid in the general context. The result is based on the observation that the time taken by any system to move to a distinguishable (nearly orthogonal) quantum state is a universal quantity that depends solely on the temperature. At equilibrium the net information flow between two systems must vanish, and this happens when two systems transit the same number of distinguishable states in the course of their interaction.

Power and the Senses: The Embattled Sensescapes of Savonarolan Florence
Creators: name: OOI, RAY HUA
Publisher: name: Monash University
Year: 2023
Subjects: Historical studies not elsewhere classified

description: This thesis explores the relationship between the senses and the contestation of power in Florence during the Savonarolan period (1494-1498). This thesis has demonstrated that historical actors in this period consciously produced sensory experiences as a means of structuring their social relationships and asserting dominance over others. Accordingly, this thesis has developed a new methodology for interpreting and analysing primary sources for actions conducive to the sensorial construction of physical and imagined environments. This has shed new light on the senses as an important yet overlooked facet of human agency in the realms of social and political behaviour.

A Detailed Model Grid for Solid Planets from 0.1 through 100 Earth Masses

description: This paper describes a new grid for the mass-radius relation of 3-layer exoplanets within the mass range of 0.1 through 100 Earth Masses. The 3 layers are: Fe (epsilon iron), MgSiO3 (including both the perovskite phase, post-perovskite phase, and its dissociation at ultra-high pressures), and H2O (including Ices Ih, III, V, VI, VII, X, and the superionic phase along the melting curve). We discuss the current state of knowledge about the equations of state (EOS) that influence these calculations and the improvements used in the new grid. For the 2-layer model, we demonstrate the utility of contours on the mass-radius diagrams. Given the mass and radius input, these contours can be used to quickly determine the important physical properties of a planet including its p0 (central pressure), p1/p0 (core-mantle boundary pressure over central pressure), CMF (core mass fraction) or CRF (core radius fraction). For the 3-layer model, a curve segment on the ternary diagram represents all possible relative mass proportions of the 3 layers for a given mass-radius input. These ternary diagrams are tabulated into Table3 with the intent to make comparison to observations easier. How the presence of Fe in the mantle affects the mass-radius relations is also discussed in a separate section. A dynamic and interactive tool to characterize and illustrate the interior structure of exoplanets built upon models in this paper is available on the website: http://www.cfa.harvard.edu/~lzeng

Year: 2016

description: In the exhibition, SYNERGY, Alicia Hunsicker investigates the powerful combination of art and science to produce creations greater than the sum of their separate parts. With science as a point of depaerture, Hunsicker paints vibrant swirling organisms that reveal a cosmic discussion about the nature of all things. Rather than depict microscopic particles or cosmic bodies with pure scientific objectivity, Hunsicker's images are infused with a life force of joyful exhuberance.
The Trispectrum in the Effective Theory of Inflation with Galilean symmetry

description: We calculate the trispectrum of curvature perturbations for a model of inflation endowed with Galilean symmetry at the level of the fluctuations around an FRW background. Such a model has been shown to posses desirable properties such as unitarity (up to a certain scale) and non-renormalization of the leading operators, all of which point towards the reasonable assumption that a full theory whose fluctuations reproduce the one here might exist as well as be stable and predictive. The cubic curvature fluctuations of this model produce quite distinct signatures at the level of the bispectrum. Our analysis shows how this holds true at higher order in perturbations. We provide a detailed study of the trispectrum shape-functions in different configurations and a comparison with existent literature. Most notably, predictions markedly differ from their P(X,ϕ) counterpart in the so called equilateral trispectrum configuration. The zoo of inflationary models characterized by somewhat distinctive predictions for higher order correlators is already quite populated; what makes this model more compelling resides in the above mentioned stability properties.

description: Graph knowledge models and ontologies are very powerful modeling and re asoning tools. We propose an effective approach to model network attacks and attack prediction which plays important roles in security management. The goals of this study are: First we model network attacks, their prerequisites and consequences using knowledge representation methods in order to provide description logic reasoning and inference over attack domain concepts. And secondly, we propose an ontology-based system which predicts potential attacks using inference and observing information which provided by sensory inputs. We generate our ontology and evaluate corresponding methods using CAPEC, CWE, and CVE hierarchical datasets. Results from experiments show significant capability improvements comparing to traditional hierarchical and relational models. Proposed method also reduces false alarms and improves intrusion detection effectiveness.
