description: We present photometry at 3-24um for all known members of the Upper Scorpius association (~11 Myr) based on all images of these objects obtained with the Spitzer Space Telescope and the Wide-field Infrared Survey Explorer. We have used these data to identify the members that exhibit excess emission from circumstellar disks and estimate the evolutionary stages of these disks. Through this analysis, we have found ~50 new candidates for transitional, evolved, and debris disks. The fraction of members harboring inner primordial disks is <10% for B--G stars (M>1.2 Msun) and increases with later types to a value of ~25% at >=M5 (M<=0.2 Msun), in agreement with the results of previous disk surveys of smaller samples of Upper Sco members. These data indicate that the lifetimes of disks are longer at lower stellar masses, and that a significant fraction of disks of low-mass stars survive for at least ~10 Myr. Finally, we demonstrate that the distribution of excess sizes in Upper Sco and the much younger Taurus star-forming region (~1 Myr) are consistent with the same, brief timescale for clearing of inner disks.

description: During May 2012, the CERN-CNGS neutrino beam has been operated for two weeks for a total of 1.8 10^17 pot in bunched mode, with a 3 ns narrow width proton beam bunches, separated by 100 ns. This tightly bunched beam structure allows a very accurate time of flight measurement of neutrinos from CERN to LNGS on an event-by-event basis. Both the ICARUS-T600 PMT-DAQ and the CERN-LNGS timing synchronization have been substantially improved for this campaign, taking ad-vantage of additional independent GPS receivers, both at CERN and LNGS as well as of the deployment of the "White Rabbit" protocol both at CERN and LNGS. The ICARUS-T600 detector has collected 25 beam-associated events; the corresponding time of flight has been accurately evaluated, using all different time synchronization paths. The measured neutrino time of flight is compatible with the arrival of all events with speed equivalent to the one of light: the difference between the expected value based on the speed of light and the measured value is tof_c - tof_nu = (0.10 \pm 0.67stat. \pm 2.39syst.) ns. This result is in agreement with the value previously reported by the ICARUS collaboration, tof_c - tof_nu = (0.3 \pm 4.9stat. \pm 9.0syst.) ns, but with improved statistical and systematic errors.

description: We derived a post-Newtonian (PN) inspiral only gravitational waveform for unequal mass, spinning black hole binaries. Towards the end of the inspiral the larger spin dominates over the orbital angular momentum (while the smaller spin is negligible), hence the name Spin-Dominated Waveforms (SDW). Such systems are common sources for future gravitational wave detectors and during the inspiral the largest amplitude waves are emitted exactly in its last part. The SDW waveforms emerge as a double expansion in the PN parameter and the ratio of the orbital angular momentum to the dominant spin.

XMM-Newton observations of the Galactic Centre Region - I: The distribution of low-luminosity X-ray sources

description: We exploit XMM-Newton archival data in a study of the extended X-ray emission emanating from the Galactic Centre (GC) region. EPIC-pn and EPIC-MOS observations, with a total exposure approaching 0.5 and 1 Ms respectively, were used to create mosaiced images of a 100 pc x 100 pc region centred on Sgr A* in four bands covering the 2-10 keV energy range. We have also constructed a set of narrow-band images corresponding to the neutral iron fluorescence line at 6.4 keV and the K-shell lines at 6.7 keV and 6.9 keV from helium-like and hydrogenic iron. We use a combination of spatial and spectral information to decompose the GC emission into three distinct components. These comprise: the emission from hard X-ray emitting unresolved point sources; the reflected continuum and fluorescent line emission from dense molecular material; and the soft diffuse emission from thermal plasma in the temperature range, kT ~ 0.8-1.5 keV. We show that the unresolved-source component accounts for the bulk of the 6.7-keV and 6.9-keV line emission. We fit the observed X-ray surface brightness distribution with an empirical 2-d model, which we then compare with a 3-d mass-model prediction for the old stellar population in the GC. The X-ray surface brightness falls-off more rapidly with angular offset from Sgr A* than predicted. One interpretation is that the 2-10 keV X-ray emissivity increases from 5 x 10^27 erg s^-1 Msun^-1 at 20' up to almost twice this value at 2'. Alternatively, some refinement of the mass model may be required. The unresolved hard X-ray emitting source population, on the basis of spectral comparisons, is most likely dominated by magnetic CVs. We use the X-ray observations to set constraints on the number density of such sources. Our analysis does not support the conjecture that a significant fraction of the hard X-ray emission from the GC originates in very-hot diffuse thermal plasma.

description: The suppression and collective flow of open and hidden heavy flavor in ultra-relativistic heavy ion collisions is studied with the partonic transport model Boltzmann Approach to MultiParton Scatterings (BAMPS). Charm and bottom quarks interact with the rest of the medium via elastic scatterings with an improved Debye screening and a running coupling. Heavy flavor electron data from RHIC can only be described if the cross section is multiplied with K=3.5 to mimic the contribution from radiative processes. With the same value for K we compare to elliptic flow data of D mesons at the LHC and find a good agreement. However, the nuclear modification factor of D mesons, non-prompt J/psi, muons, and electrons at the LHC is underestimated in our calculations. In addition, we present first BAMPS results on the suppression and elliptic flow of J/psi mesons, which are treated in the same framework.

description: Coronavirus (COVID-19) has had far-reaching impacts on the cattle market. The most publicized impacts have been related to the backlog of finished cattle associated with reduced slaughter rates, which resulted in lower finished cattle prices. Additionally, the reduced finished cattle slaughter resulted in lower feeder cattle prices and delayed marketing of feeder cattle and calves by many cattle producers. However, finished cattle and feeder cattle are not the only markets that influence returns for Tennessee cattle producers. Another major income source for many Tennessee cattle producers comes in the form of slaughter cows. As cows mature and become less reproductively efficient, producers will cull them out of the herd and sell them as slaughter cows. Slaughter cow sales make up 15 to 20 percent of the gross income on most cow-calf operations (Durst et al., 2017). The relatively large percentage of gross income from slaughter cows points to the importance of this market to cow-calf operations. Therefore, it is important to evaluate the impact COVID-19 had on the slaughter cow market and its implications for cow-calf producers in Tennessee. The slaughter cow market is driven by supply and demand for ground beef. There are three primary sources of beef that help fulfill ground beef demand, including trimmings from finished cattle, lean beef imports and slaughter cows. In addition to the three listed sources of ground beef, there are times when whole muscle cuts (i.e., chucks, rounds) from finished cattle are ground to fulfill ground beef demand. The purpose of this publication is to illustrate how slaughter cow prices in Tennessee have been influenced by COVID-19. This will be accomplished by evaluating mature cow slaughter and slaughter cow prices in Tennessee during the first five months of 2020, as compared to previous years.

description: We report calculations of energy levels, radiative rates, and electron impact excitation rates for transitions in Li-like ions with 12 <= Z <= 20. The GRASP (general-purpose relativistic atomic structure package) is adopted for calculating energy levels and radiative rates, while for determining the collision strengths and subsequently the excitation rates, the Dirac atomic R-matrix code DARC is used. Oscillator strengths, radiative rates, and line strengths are reported for all E1, E2, M1, and M2 transitions among the lowest 24 levels of the Li-like ions considered. Collision strengths have been averaged over a Maxwellian velocity distribution, and the effective collision strengths obtained are reported over a wide temperature range up to 10$^{7.4}$ K. Additionally, lifetimes are also listed for all calculated levels of the above ions. Finally, extensive comparisons are made with available results in the literature, as well as with our parallel calculations for all parameters with the Flexible Atomic Code FAC in order to assess the accuracy of the reported results.

Precision measurement of the Z invisible width with the CMS experiment
Creators: name: Breeze, Shane Davy
Publisher: name: Imperial College London
Year: 2019

description: A precision measurement of the partial width of the Z boson decay to an invisible final state is reported. Events from proton-proton collisions provided by the Large Hadron Collider at a centre-of-mass energy of 13 TeV are collected by the Compact Muon Solenoid experiment with the invisibly decaying Z bosons inferred from a hadronic recoil. The data collected corresponds to a total integrated luminosity of 35.9 fb−1. The invisible width is measured to be 512+16−15 MeV, consistent with the standard model. This is a competitive result to previous measurements performed at the Large Electron Positron collider. The measurement is systematically dominated by uncertainties associated with the measurement of the energy scale of the recoiling hadronic system.

description: The discovery of a population of massive, compact and quiescent early-type galaxies has changed the view on plausible formation scenarios for the present day population of elliptical galaxies. Traditionally assumed formation histories dominated by 'single events' like early collapse or major mergers appear to be incomplete and have to be embedded in the context of hierarchical cosmological models with continuous gas accretion and the merging of small stellar systems (minor mergers). Once these processes are consistently taken into account the hierarchical models favor a two-phase assembly process and are in much better shape to capture the observed trends. We review some aspects of recent progress in the field.

Sample efficiency, transfer learning and interpretability for deep reinforcement learning
Creators: name: Arulkumaran, Kailash
Publisher: name: Imperial College London

description: Deep learning has revolutionised artificial intelligence, where the application of increased compute to train neural networks on large datasets has resulted in improvements in real-world applications such as object detection, text-to-speech synthesis and machine translation. Deep reinforcement learning (DRL) has similarly shown impressive results in board and video games, but less so in real-world applications such as robotic control. To address this, I have investigated three factors prohibiting further deployment of DRL: sample efficiency, transfer learning, and interpretability. To decrease the amount of data needed to train DRL systems, I have explored various storage strategies and exploration policies for episodic control (EC) algorithms, resulting in the application of online clustering to improve the memory efficiency of EC algorithms, and the maximum entropy mellowmax policy for improving the sample efficiency and final performance of the same EC algorithms. To improve performance during transfer learning, I have shown that a multi-headed neural network architecture trained using hierarchical reinforcement learning can retain the benefits of positive transfer between tasks while mitigating the interference effects of negative transfer. I additionally investigated the use of multi-headed architectures to reduce catastrophic forgetting under the continual learning setting. While the use of multiple heads worked well within a simple environment, it was of limited use within a more complex domain, indicating that this strategy does not scale well. Finally, I applied a wide range of quantitative and qualitative techniques to better interpret trained DRL agents. In particular, I compared the effects of training DRL agents both with and without visual domain randomisation (DR), a popular technique to achieve simulation-to-real transfer, providing a series of tests that can be applied before real-world deployment. One of the major findings is that DR produces more entangled representations within trained DRL agents, indicating quantitatively that they are invariant to nuisance factors associated with the DR process. Additionally, while my environment allowed agents trained without DR to succeed without requiring complex recurrent processing, all agents trained with DR appear to integrate information over time, as evidenced through ablations on the recurrent state.
Topics in complex multiscale systems: theory and computations of noise-induced transitions and transport in heterogenous media
Creators: name: Addy, Douglas
Publisher: name: Imperial College London
Year: 2019

description: The present work seeks to address three different problems that have a multiscale nature, we apply different techniques from multiscale analysis to treat these problems. We introduce the field of multiscale analysis and motivate the need for techniques to bridge between scales, presenting the history of some common methods, and an overview of the current state of the field. The remainder of the work deals with the treatment of these problems, one motivated by reaction rate theory, and two from multiphase flow. These superficially have little relation with each other, but the approaches taken share similarities and the results are the same - an average picture of the microscopic description informs the macroscale. In Chapter 2 we address an asymmetric potential with a microscale, showing that the interaction between this microscale and the noise causes a first-order phase transition. This induces a metastable state which we observe and characterise: showing that the stability of this state depends on the strength of the tilt, and that the phase transition is inherently different to the symmetric case. In Chapter 3 we investigate the nucleation and coarsening process of a two-phase flow in a corrugated channel using a Cahn--Hilliard Navier--Stokes model. We show that several flow morphologies can be present depending on the channel geometry and the initial random condition. We rationalise this with a static energy model, predicting the preferential formation of one morphology over another and the existence of a first-order phase-transition from smooth slug flow to discontinuous motion when the channel is strongly corrugated. In Chapter 4 we address a model for interfacial flows in porous geometries, formulating an finite-element model for the equations. Within this framework we solve two equations in the microscale to obtain effective coefficients decoupling the two scales from each other. Finite-difference simulations of the macroscopic flow recover results from literature, supporting robustness of the method.

description: Riassunto. Nella revisione del concetto di stile intrapresa da Hans Belting,
 specialmente in Bild und Kult (1990), un posto centrale è occupato dalla nozione di
 “modi dello stile”. Tale nozione era stata introdotta da Ernst Kitzinger per comprendere
 quelle immagini della tarda antichità che mostrano un impiego simultaneo di differenti
 modalità pittoriche: il caso esemplare, vera e propria “cartina di tornasole”, è rappresentato
 dall’icona mariana del monastero di S. Caterina del Sinai. Benché Belting riconosca che la
 nozione di modi dello stile abbia aperto una breccia nel campo della storiografia artistica,
 egli ritiene più appropriato parlare di convenzioni dell’immagine. In tal modo, egli sposta
 la questione da un piano stilistico a uno relativo a una tipologia delle immagini. Abstract. The notion of “stylistic modes” occupies a core position in the review of the
 concept of style carried on by Hans Belting, especially in Bild und Kult (1990). Such a notion
 was introduced by Ernst Kitzinger in order to understand those late antique images that
 show a simultaneous use of different modalities of painting: the typical case in point – a real
 litmus test – is the icon of the Virgin from the monastery of St. Catherine at Mount Sinai.
 Although Belting recognizes that the notion of stylistic modes opened a breach in the field
 of art historiography, he nonetheless considers more appropriate to speak of conventions of
 images. In doing so, he shifts the question from a stylistic viewpoint to a viewpoint related
 to a typology of images.

description: The performance of advanced magnetic tunnel junctions build of ferromagnetic (FM) electrodes and MgO as insulating barrier depends decisively on the properties of the FM/insulator interface. Here, we investigate interface formation between the half-metallic compound Co2MnSi (CMS) and MgO by means of Auger electron spectroscopy, low energy electron diffraction and low energy photoemission. The studies are performed for different annealing temperatures TA and MgO layer coverages (4, 6, 10, 20 and 50 ML). Thin MgO top layers (t_MgO<=10 ML) show distinct surface crystalline distortions, which can only be partly healed out by annealing and furthermore lead to distinct adsorption of carbon species after the MgO surface is exposed to air. For t_MgO> 10 ML the MgO layer surface exhibits clearly improved crystalline structure and hence only marginal amounts of adsorbates. We attribute these findings to MgO misfit dislocations occurring at the interface, inducing further defects throughout the MgO layer for up to at least 10 ML. Furthermore, spin-polarized photoemission spectra of the CMS/MgO interface are obtained for MgO coverages up to 20 ML, showing a clear positive spin polarization near the Fermi energy in all cases.

description: With nearly 2000 entries in the Registry of Research Data Repositories (re3data.org, November 2017) researchers are confronted with a plethora of repositories to deposit research data. Given the diversity of these services, we have noticed that researchers find it challenging to make an informed decision, especially when they are dealing with data from the so-called “long tail” (small, diverse, individual, less standardized data). Although, re3data.org provides a very comprehensive list of criteria (i.e. filters) to narrow down the number of choices, there is still advice needed, for example, on evaluating the importance of a criteria (e.g. type of repository) or the impact of a certain choice (e.g. which PID?). In this poster presentation, we take the perspective of the research data management helpdesk, a central service facility at the Friedrich-Schiller University in Jena (Germany), and investigate how we could address this selection challenge. The aim is to develop a practical guide for researchers from domains where there is no obvious choice or well-established repository available (i.e. the long tail) and where researchers rely on general-purpose repositories. In a first step, we compared five generic repositories for long tail data (Figshare, Zenodo, Dryad, RADAR, Digital Library Thuringia) using the individual descriptions and properties on re3data.org. For some criteria, the information content in re3data.org was rather limited, so we also explore the individual websites of the repository providers. For example, the criteria “Quality Management” only says whether a repository provider does quality management, but not what exactly that means. Another example for rather sparse information is the level of data curation available and applied to the data in a certain repository. Such information would be helpful in the evaluation process. In a second step, we took a number of real cases from our work at the helpdesk and investigated the matching between the researcher’s intentions and expectations with the means and information available to evaluate a repository (both, at re3data.org, repository website). This might be straightforward, for example, if the intention is to make data citable, where one needs to check whether a PID is provided. But it might more difficult, for example, if a researcher would like to assess the visibility a dataset may gain from publishing with a certain repository. In this case, one should look at a number of properties (e.g. Metrics, Sydications, API, Licences) with rather technical information.

description: The idea of holography in gravity arose from the fact that the entropy of black holes is given by their surface area. The holography encountered in gauge/gravity duality has no such relation however; the boundary surface can be placed at an arbitrary location in AdS space and its area does not give the entropy of the bulk. The essential issues are also different between the two cases: in black holes we get Hawking radiation from the `holographic surface' which leads to the information issue, while in gauge/gravity duality there is no such radiation from the boundary surface. To resolve the information paradox we need to show that there are real degrees of freedom at the horizon of the hole; this is achieved by the fuzzball construction. While the fuzzball has no interior to the horizon, we argue that an auxiliary spacetime can be constructed to continue the collective dynamics of fuzzball for times of order the crossing time; this is an analogue of `complementarity'.

description: Over the past decades various Roman-period river barges were found in the Lower Rhine region. These ships were large vessels of over twenty meters in length. Many were excavated in order to document the constructions and some were lifted from the ground and conserved for future display. The first barges that were found (fifty years ago), the Zwammerdam ships, were among those that were preserved. This has more recently allowed for a re-examination of their ship constructions using more modern techniques. Research on the constructions including a dendroarchaeological study of the timbers has been undertaken by Y. Vorst. The provenance of the wood has been studied by both researchers, based on a recently published approach (Visser 2021). This approach uses networks to visualize and explore dendrochronological relations based on similarity. In addition, these networks give insight in other aspects of ship building practices, such as wood use and the construction. The combined studies have led to a better understanding of past practices in shipbuilding and timber transport and use during the Roman period.

description: Understanding how the mechanical behavior of materials deviates at the nanoscale from the macroscopically established concepts is a key challenge of particular importance for graphene, given the complex interplay between its nanoscale morphology and electronic properties. In this work, the (sub-) nanometer wavelength periodic rippling of suspended graphene nanomembranes has been realized by thermal strain-engineering and investigated using Scanning Tunneling Microscopy. This allows us to explore the rippling of a crystalline membrane with wavelengths comparable to its lattice constant. The observed nanorippling mode violates the predictions of the continuum model, and evidences the breakdown of the plate idealization of the graphene monolayer. Nevertheless, microscopic simulations based on a quantum mechanical description of the chemical binding accurately describe the observed rippling mode and elucidate the origin of the continuum model breakdown. Spatially resolved tunneling spectroscopy measurements indicate a substantial influence of the nanoripples on the local electronic structure of graphene and reveal the formation of one-dimensional electronic superlattices.

description: Der Aufsatz präsentiert die Ergebnisse einer Untersuchung zur Ausstattung städtischer Rechnungsprüfungsämter mit Beamten- und Arbeitnehmerstellen, zur Eingruppierung dieser Stellen sowie zur Qualifikations- und Altersstruktur des Personals. Es wird gezeigt, dass es zwischen den Rechnungsprüfungsämtern vergleichbarer Städte zum Teil große Unterschiede im Stellenvolumen gibt. Budgets zur Unterstützung durch Externe (z. B. Wirtschaftsprüfer) entsprechen im Durchschnitt nur 1,6 % der Gesamtkapazität der Ämter. In den westdeutschen Bundesländern ist mehr Prüfungspersonal verbeamtet als in den ostdeutschen und die Stellen sind im Durchschnitt höher eingruppiert. Dennoch ist auch im Westen die Eingruppierung vieler Stellen niedriger als es vorliegende Stellenbewertungsgutachten nahelegen. 82 % der Beschäftigten der Rechnungsprüfungsämter sind Akademiker. Aber nur 13 % verfügen über einen Studienabschluss auf Masterniveau. 62 % der Beschäftigten sind 50 Jahre alt und älter. Die enorme personelle Erneuerung in den nächsten Jahren führt zu viel Wissensverlust und Bedarf an prüfungsspezifischen Weiterbildungsangeboten, eröffnet aber auch die Chance einer zügigeren Umstrukturierung, etwa zur Umsetzung des Leitbilds einer modernen kommunalen Rechnungsprüfung.

description: We explore Leibniz's understanding of the differential calculus, and argue that his methods were more coherent than is generally recognized. The foundations of the historical infinitesimal calculus of Newton and Leibniz have been a target of numerous criticisms. Some of the critics believed to have found logical fallacies in its foundations. We present a detailed textual analysis of Leibniz's seminal text Cum Prodiisset, and argue that Leibniz's system for differential calculus was free of contradictions.

Star Formation in Atomic Gas

description: Observations of nearby galaxies have firmly established, over a broad range of galactic environments and metallicities, that star formation occurs exclusively in the molecular phase of the interstellar medium (ISM). Theoretical models show that this association results from the correlation between chemical phase, shielding, and temperature. Interstellar gas converts from atomic to molecular only in regions that are well shielded from interstellar ultraviolet (UV) photons, and since UV photons are also the dominant source of interstellar heating, only in these shielded regions does the gas become cold enough to be subject to Jeans instability. However, while the equilibrium temperature and chemical state of interstellar gas are well-correlated, the time scale required to reach chemical equilibrium is much longer than that required to reach thermal equilibrium, and both timescales are metallicity-dependent. Here I show that the difference in time scales implies that, at metallicities below a few percent of the Solar value, well-shielded gas will reach low temperatures and proceed to star formation before the bulk of it is able to convert from atomic to molecular. As a result, at extremely low metallicities, star formation will occur in a cold atomic phase of the ISM rather than a molecular phase. I calculate the observable consequences of this result for star formation in low metallicity galaxies, and I discuss how some current numerical models for H2-regulated star-formation may need to be modified.

ModRule: A user-centric mass housing design platform
Creators: name: Lo, Tian Tian; Schnabel
Publisher: name: Open Access Victoria University of Wellington | Te Herenga Waka
Year: 2021
Subjects: Uncategorized

description: This paper presents a novel platform, ModRule, designed and developed to promote and facilitate collaboration between architects and future occupants during the design stage of mass housing buildings. Architects set the design-framework and parameters of the system, which allows the users to set their space requirements, budgets, etc., and define their desired way of living. The system utilizes gamification methodologies as a reference to promote incentives and user-friendliness for the layperson who has little or no architectural background. This enhanced integration of a both bottom-up approach (user-centric/player) with a top-down approach (architect-centric/game-maker) will greatly influence how architects design high rise living. By bridging the gap between the architect and the user, this development aims to instill a greater sense of belonging to people, as well as providing architects with a better understanding of how to give people more control over their living spaces. The paper also presents an evaluation of a design process that employed ModRule.
Why sauropods had long necks; and why giraffes have short necks

description: The necks of the sauropod dinosaurs reached 15 m in length: six times longer than that of the world record giraffe and five times longer than those of all other terrestrial animals. Several anatomical features enabled this extreme elongation, including: absolutely large body size and quadrupedal stance providing a stable platform for a long neck; a small, light head that did not orally process food; cervical vertebrae that were both numerous and individually elongate; an efficient air-sac-based respiratory system; and distinctive cervical architecture. Relevant features of sauropod cervical vertebrae include: pneumatic chambers that enabled the bone to be positioned in a mechanically efficient way within the envelope; and muscular attachments of varying importance to the neural spines, epipophyses and cervical ribs. Other long-necked tetrapods lacked important features of sauropods, preventing the evolution of longer necks: for example, giraffes have relatively small torsos and large, heavy heads, share the usual mammalian constraint of only seven cervical vertebrae, and lack an air-sac system and pneumatic bones. Among non-sauropods, their saurischian relatives the theropod dinosaurs seem to have been best placed to evolve long necks, and indeed they probably surpassed those of giraffes. But 150 million years of evolution did not suffice for them to exceed a relatively modest 2.5 m.
