description: In this study we follow up our recent paper (Monteiro et al. 2020) and present a homogeneous sample of fundamental parameters of open clusters in our Galaxy, entirely based on Gaia DR2 data. We used published membership probability of the stars derived from Gaia DR2 data and applied our isochrone fitting code, updated as in Monteiro et al. (2020), to GB and GR Gaia DR2 data for member stars. In doing this we take into account the nominal errors in the data and derive distance, age, and extinction of each cluster. This work therefore provides parameters for 1743 open clusters and, as a byproduct, a list of likely not physical or dubious open clusters is provided as well for future investigations. Furthermore, it was possible to estimate the mean radial velocity of 831 clusters (198 of which are new and unpublished so far) using stellar radial velocities from Gaia DR2 catalog. By comparing the open cluster distances obtained from isochrone fitting with those obtained from a maximum likelihood estimate of individual member parallaxes, we found a systematic offset of $(-0.05\pm0.04)$mas.

description: EPIC-WE is an EU Horizon Europe Research and Innovation project which includes 12 EPIC-WE Partners from five countries. The project’s overall methodology is based on Design-Based Research (abbreviated as DBR; methodologically drawing on McKenney & Reeves, 2019).

The present document is the third of four individual subreports that together make up the EPIC-WE D3.1 report “Protocols for carrying out cultural game jams in local sites”

D3.1 Protocol 1: Quadruple Helix Cultural Innovation: EPIC-WE Quadruple Helix Cultural Ecosystems and Cultural Hubs (Initial protocol)

D3.1 Protocol 2: Cultural Game Jam Kit: EPIC-WE Cultural Game Jam Processes, Phases, Methods, and Tools (Initial protocol)

D3.1 Protocol 3: EPIC-WE Research Protocol for Cultural Game Jams in Local Sites (Initial protocol)

D3.1 Protocol 4: EPIC-WE Practical Protocol for Cultural Game Jams in Local Sites (Initial protocol)

As a whole, the 4 subreports support the EPIC-WE project in carrying out its research and innovations interventions on the macro-level (EPIC-WE Quadruple Helix Cultural Innovation Ecosystem), on the meso-level (EPIC-WE Cultural Hub), and on the micro-level (EPIC-WE Cultural Game Jams).

The Protocol 1 describes the ‘design’ of the EPIC-WE Quadruple Helix Cultural Innovation Ecosystem and Cultural Hubs, which brings together Higher Education Institutions (HEI), Creative Industries (CI), Cultural Heritage Institutions (CHI), and Youth Citizens (YCs), to do research and innovation together, thus connecting and operationalising the four helices of the QH ecosystem. This epistemic and practical partnership across helices uses the ‘design’ of the EPIC-We Cultural Game Jam Kit (Protocol 2) and the ‘construction’ of the EPIC-WE Research Protocol (Protocol 3) to innovate and research the format of cultural game jams, game-making as a form of culture-making, and the creation of games through and for culture. The Protocol 4, EPIC-WE Practical Protocol, describes, in a beginning way, how the Quadruple Helix Cultural Partners can work together in Cultural Hubs to facilitate Cultural Game Jams that positions game-making as a form of culture-making and leads to the creation of games through and for culture.

description: The file contains the protocol for a study entitled “Exposure risk, burden of disease, and access to care: comparison of tuberculosis and COVID-19 in Lima, Peru”. This protocol was approved by the Institutional Review Board of the Institute of Tropical Medicine, Antwerp, Belgium on 23 June 2021. A Spanish version of the study protocol, approved by the Ethics Committee of the Universidad Peruana Cayetano Heredia is also available via Figshare. Introduction: Peru is one of the countries with the highest burden of tuberculosis (TB) in the Latin American region. In addition, it is among the countries most affected by the SARS-CoV-2/COVID-19 epidemic. Since TB and COVID-19 share transmission mechanisms and risk factors at individual and at population level, overlaps can be expected in the burden of disease caused by these two conditions. Objectives: To determine and explain overlapping heterogeneities in the risk and burden of TB and COVID-19 in Lima. The specific objectives of the study are the following: 1) Determine the geographical distribution and burden of TB and COVID-19 disease in the 50 districts of the Lima and Callao provinces (using quantitative analysis of secondary data), 2) Evaluate the risk of exposure to TB and COVID-19 (using quantitative and qualitative methods), 3) Describe the changes in the delivery of TB-related health services and in the health-seeking itineraries of TB patients during the pandemic (using qualitative methods), and 4) Identify patterns of vulnerability and resilience (based on joint analysis of mixed-methods interdisciplinary data). Methods: Methods: A convergent parallel-design mixed-methods study ([QUAL] + [QUAN]) will be developed in which both strands constantly inform each other. The quantitative research strand will begin by evaluating the overlaps in the burden of TB and COVID-19 and their association with factors from publicly available district-level data (secondary data). A parallel qualitative strand will begin by generating detailed ethnographic data to enrich the exposure risk assessment (primary data).

title: Unnameable Text: Life, Critique and Uncriticizability from Kant to Benjamin
Creators: name: Law, Christopher
Publisher: name: Goldsmiths, University of London
Year: 2022

description: This project explores the idea of ‘uncriticizability’, a term used on rare but significant occasions in Walter Benjamin’s writing about literature, art, and criticism. Serving both as a framework for Benjamin’s recognition of the foundational crisis undergone by criticism in the late eighteenth century and as a cornerstone of his concerns about the possibilities and limits of criticism in the 1920s and early 1930s, uncriticizability plays a multi-faceted but often enigmatic role in the history and philosophy of modern literature and literary criticism. The thesis begins by considering the diverse implications of Immanuel Kant’s entanglement of poetic form and organic life in his Critique of the Power of Judgment. After outlining recursive tensions in Kant’s attempts to find a place for poetry in the third Critique, I show how the theorists of early German Romanticism, rather than assuming Kant to have successfully closed his critical system, developed a theory that imagined literature’s ‘life’ as its infinite capacity for critical renewal in historically diverse contexts. Through close engagements with Benjamin’s early work on criticism and language, I offer a new reading of his doctoral dissertation, ‘The Concept of Criticism in German Romanticism’, arguing that the idea of literature’s ‘criticizability’ here arises as a conceptual solution to a singular linguistic problem, which ‘uncriticizability’ is more likely to capture. In registering the continued relevance of pre-Kantian philosophies of nature, uncriticizability, however, simultaneously confronts literary criticism with its own, apparently inescapable grounding in myth. This argument is pursued through readings of Goethe’s Elective Affinities and Benjamin’s essay thereon, as well as a range of other literary, philosophical, and scientific texts, both exalted and obscure. The problem of uncriticizability, I argue, captures a trait shared between poetry and politics: like literature, politics is irreducible to the temporal conditions that render it fully comprehensible.

description: A 227 ksec Chandra Observatory X-ray image of the hot plasma in the Hydra A cluster has revealed an extensive cavity system. The system was created by a continuous outflow or a series of bursts from the nucleus of the central galaxy over the past 200-500 Myr. The cavities have displaced 10% of the plasma within a 300 kpc radius of the central galaxy, creating a swiss-cheese-like topology in the hot gas. The surface brightness decrements are consistent with empty cavities oriented within 40 degrees of the plane of the sky. The outflow has deposited upward of 10^61 erg into the cluster gas, most of which was propelled beyond the inner ~100 kpc cooling region. The supermassive black hole has accreted at a rate of approximately 0.1-0.25 solar masses per year over this time frame, which is a small fraction of the Eddington rate of a ~10^9 solar mass black hole, but is dramatically larger than the Bondi rate. Given the previous evidence for a circumnuclear disk of cold gas in Hydra A, these results are consistent with the AGN being powered primarily by infalling cold gas. The cavity system is shadowed perfectly by 330 MHz radio emission. Such low frequency synchrotron emission may be an excellent proxy for X-ray cavities and thus the total energy liberated by the supermassive black hole.

description: We report on precision spectroscopy of sub-wavelength confined molecular gases. This was obtained by rovibrational selective reflection of $\mathrm{NH_3}$ and $\mathrm{SF_6}$ gases using a quantum cascade laser at $λ\approx 10.6 μm$. Our technique probes molecules at micrometric distances ($\approx λ/2π$) from the window of a macroscopic cell with sub-MHz resolution, allowing molecule-surface interaction spectroscopy. We exploit the linearity and high-resolution of our technique to gain novel spectroscopic information on the $\mathrm{SF_6}$ greenhouse gas, useful for enriching molecular databases. The natural extension of our work to thin-cells will allow compact frequency references and improved measurements of the Casimir-Polder interaction with molecules.

description: We formulate an algebraic relativistic method of scattering for systems with spatially dependent mass based on the J-matrix method. The reference Hamiltonian is the three-dimensional Dirac Hamiltonian but with a mass that is position-dependent and having a constant asymptotic limit. Additionally, this effective mass distribution is locally represented in a finite dimensional function subspace. The spinor couples to spherically symmetric vector and pseudo scalar potentials that are short-range such that they are accurately represented by their matrix elements in the same finite dimensional subspace. We calculate the relativistic phase shift as a function of energy for a given configuration and study the effect of spatial variation of the mass on the energy resonance structure.

description: The instrumental layout and technical realisation of the neutron resonant spin echo (NRSE) spectrometer RESEDA at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching, Germany, is presented. RESEDA is based on a longitudinal field configuration, boosting both dynamic range and maximum resolution of the spectrometer compared to the conventional transverse layout. The resonant neutron spin echo technique enables the realisation of two complementary implementations: A longitudinal NRSE (LNRSE) option comparable to the classical neutron spin echo (NSE) method for highest energy resolution and large momentum transfers as well as a Modulation of Intensity with Zero Effort (MIEZE) option for depolarising samples or sample environments such as high magnetic fields, and strong incoherent scattering samples. With their outstanding dynamic range, exceeding nominally seven orders of magnitude, both options cover new fields for ultra-high resolution neutron spectroscopy in hard and soft condensed matter systems. In this paper the concept of RESEDA as well as the technical realisation along with reference measurements are reported.

description: Domain dynamics in the Piezoresponse Force Spectroscopy (PFS) experiment is studied using the combination of local hysteresis loop acquisition with simultaneous domain imaging. The analytical theory for PFS signal from domain of arbitrary cross-section is developed and used for the analysis of experimental data on Pb(Zr,Ti)O3 polycrystalline films. The results suggest formation of oblate domain at early stage of the domain nucleation and growth, consistent with efficient screening of depolarization field within the material. The fine structure of the hysteresis loop is shown to be related to the observed jumps in the domain geometry during domain wall propagation (nanoscale Barkhausen jumps), indicative of strong domain-defect interactions.

By a polynomial argument this 8-phi-7 summation is transformed to another multivariable 8-phi-7 summation which, by taking a suitable limit, is reduced to a new multivariable extension of the nonterminating 6-phi-5 summation. The latter is then extended, by analytic continuation, to a new multivariable extension of Bailey's very-well-poised 6-psi-6 summation formula.

An oral history of the Sikhs in British Columbia, 1920-1947

Publisher: name: University of British Columbia
Year: 2011

description: This thesis recognizes the value of using a variety of perspectives to study the history of an ethnic minority group. The history of some groups is lacking in insider perspectives. I have attempted to add balance to the existing accounts by using an oral history approach to describe the experiences of the Sikhs living in British Columbia from 1920-1947. I am an insider, a Sikh whose grandfather was one of the original pioneers who came in the first wave of immigration in the 1904-1908 time period. These people are no longer with us, but some of their wives and children are still available to share their history with future generations. I interviewed and recorded 24 individual histories. From these I have formed a composite picture of the Sikh community in British Columbia from 1920-1947. Beginning with descriptions of social, political and cultural conditions in India and Canada at the time of arrival, we follow them through the important stages of their lives in their adopted land. They describe the journey over, settling in, adaptations, work, social life, the fight for rights, and the role of their temple and religion. We see the events and circumstances that eventually led to the Sikhs being able to call Canada their home. The many photographs, letters and documents give further insights into the lives of this distinctive group of Canadians.
Understanding collective human movement dynamics during large-scale events using big geosocial data analytics

description: With the rapid advancement of information and communication technologies, many researchers have adopted alternative data sources from private data vendors to study human movement dynamics in response to large-scale natural or societal events. Big geosocial data such as georeferenced tweets are publicly available and dynamically evolving as real-world events are happening, making it more likely to capture the real-time sentiments and responses of populations. However, precisely-geolocated geosocial data is scarce and biased toward urban population centers. In this research, we developed a big geosocial data analytical framework for extracting human movement dynamics in response to large-scale events from publicly available georeferenced tweets. The framework includes a two-stage data collection module that collects data in a more targeted fashion in order to mitigate the data scarcity issue of georeferenced tweets; in addition, a variable bandwidth kernel density estimation(VB-KDE) approach was adopted to fuse georeference information at different spatial scales, further augmenting the signals of human movement dynamics contained in georeferenced tweets. To correct for the sampling bias of georeferenced tweets, we adjusted the number of tweets for different spatial units (e.g., county, state) by population. To demonstrate the performance of the proposed analytic framework, we chose an astronomical event that occurred nationwide across the United States, i.e., the 2017 Great American Eclipse, as an example event and studied the human movement dynamics in response to this event. However, this analytic framework can easily be applied to other types of large-scale events such as hurricanes or earthquakes.

description: We develop the learning algorithm to build the architecture agnostic model of the reconfigurable optical interferometer. Programming the unitary transformation on the optical modes of the interferometer either follows the analytical expression yielding the unitary matrix given the set of phaseshifts or requires the optimization routine if the analytic decomposition does not exist. Our algorithm adopts the supervised learning strategy which matches the model of the interferometer to the training set populated by the samples produced by the device under study. The simple optimization routine uses the trained model to output the phaseshifts of the interferometer with the given architecture corresponding to the desired unitary transformation. Our result provides the recipe for efficient tuning of the interferometers even without rigorous analytical description which opens opportunity to explore new architectures of the interferometric circuits.

description: We calculate the quasiparticle dispersion and spectral weight of the quasiparticle that results when a hole is added to an antiferromagnetically ordered CuO$_2$ plane of a cuprate superconductor. We also calculate the magnon contribution to the quasiparticle spectral function. We start from a multiband model for the cuprates considered previously [Nat. Phys. \textbf{10}, 951 (2014)]. We map this model and the operator for creation of an O hole to an effective one-band generalized $t-J$ model, without free parameters. The effective model is solved using the state of the art self-consistent Born approximation. Our results reproduce all the main features of experiments. They also reproduce qualitatively the dispersion of the multiband model, giving better results for the intensity near wave vector $(π,π)$, in comparison with the experiments. In contrast to what was claimed in [Nat. Phys. \textbf{10}, 951 (2014)], we find that spin fluctuations play an essential role in the dynamics of the quasiparticle, and hence in both its weight and dispersion.

Excess and loss of entropy production for different levels of coarse-graining

description: We investigate the effect of coarse-graining on the energetics properties of a system, focusing on entropy production. As a case of study, we consider a one-dimensional colloidal particle in contact with a thermal bath, moving in a sinusoidal potential and driven out of equilibrium by a small constant force. Different levels of coarse-graining are evaluated: at first, we compare the results in the underdamped dynamics with those in the overdamped one (first coarse-graining). For large values of the viscosity, the two dynamics have the same energetic properties, while, for smaller viscosity values, the overdamped approximation produces an excess of entropy production with respect to that of the underdamped dynamics. Moreover, for further smaller values of the drag coefficient, the excess of entropy production turns into a loss. These regimes are explained by evaluating the jump statistics, observing that the inertia is able to induce multiple jumps and affect the average jump rate. The periodic shape of the potential allows us to approximate the continuous dynamics via a Markov chain, after the introduction of a suitable time and space discretization (second level of coarse-graining). This discretization procedure is implemented starting both from the underdamped and the overdamped evolution and is analyzed for different values of the viscosity.
title: Art and nature join'd : Hester Santlow and the development of dancing on the London stage, 1700-1737
Creators: name: Goff, Moira
Publisher: name: University of Kent
Year: 2021

description: The thesis deals with the dancing career of the English dancer-actress Hester Santlow (ci 690-1773), from her debut in 1706 to her retirement from the stage in 1733, with particular reference to her influence on the development of dancing on the London stage through her repertoire of entr'acte dances and her work with the dancing-masters John Weaver, John Thurmond, and Roger. The early eighteenth century was a significant period for the development of dancing. On the London stage, new forms and genres of entr'acte dances were introduced as well as two new afterpiece genres, the 'dramatic entertainments of dancing' of John Weaver (the first independent theatre works to tell a story through dance and mime alone with no spoken or sung text) and pantomimes. The thesis focusses on Santlow's repertoire of entr'acte dances, those of her dances recorded in Beauchamp-Feuillet notation, and her dancing roles in both 'dramatic entertainments of dancing' and pantomimes. In order to analyse and interpret her entr'acte and notated dances, the style and technique of early eighteenth-century dancing is reviewed, and the forms and genres of dancing on the London stage in the early 1700s are defined. For the assessment of her aflerpiece roles, Santlow's own career as an actress and the careers of several of her contemporaries, in particular the dancers and dancingmasters with whom she worked most closely, are investigated. The thesis argues that Hester Santlow made a significant contribution to the developments in dancing on the London stage during the course of her career, and that the most important of these developments, the 'dramatic entertainments of dancing' of John Weaver, could not have been produced for the London stage without her.

description: In this paper we study the electroproduction of open heavy flavor $D$- and $B$-mesons in the kinematics of future $ep$ colliders, such as the Electron Ion Collider (EIC), the Large Hadron electron Collider (LHeC) and the Future Circular Collider (FCC-he). We study in detail the dependence of the cross-sections on multiplicity of co-produced hadrons, in view of its possible sensitivity to contributions from multipomeron contributions, and discuss different observables which might be used for its study. According to our theoretical expectations, in $ep$ collisions the multipomeron contributions are small in the EIC kinematics, although they might be sizable at LHeC and FCC-he. We also provide theoretical predictions for the production cross-sections of heavy mesons in the kinematics of all the above-mentioned $ep$ colliders.

description: We study the effects of disorder in the electronic properties of graphene multilayers, with special focus on the bilayer and the infinite stack. At low energies and long wavelengths, the electronic self-energies and density of states exhibit behavior with divergences near half-filling. As a consequence, the spectral functions and conductivities do not follow Landau's Fermi liquid theory. In particular, we show that the quasiparticle decay rate has a minimum as a function of energy, there is a universal minimum value for the in-plane conductivity of order e^2/h per plane and, unexpectedly, the c-axis conductivity is enhanced by disorder at low doping, leading to an enormous conductivity anisotropy at low temperatures.

description: We detect millihertz quasi-periodic oscillations (mHz QPOs) using the Rossi X-ray Time Explorer (RXTE) from the atoll neutron-star (NS) low-mass X-ray binaries 4U 1608--52 and Aql X--1. From the analysis of all RXTE observations of 4U 1608--52 and Aql X--1, we find mHz QPOs with a significance level $>3σ$ in 49 and 47 observations, respectively. The QPO frequency is constrained between $\sim$ 4.2 and 13.4 mHz. These types of mHz QPOs have been interpreted as being the result of marginally stable nuclear burning of He on the NS surface. We also report the discovery of a downward frequency drift in three observations of 4U 1608--52, making it the third source that shows this behaviour. We only find strong evidence of frequency drift in one occasion in Aql X--1, probably because the observations were too short to measure a significant drift. Finally, the mHz QPOs are mainly detected when both sources are in the soft or intermediate states; the cases that show frequency drift only occur when the sources are in intermediate states. Our results are consistent with the phenomenology observed for the NS systems 4U 1636--53 and EXO 0748--676, suggesting that all four sources can reach the conditions for marginally stable burning of He on the NS surface. These conditions depend on the source state in the same manner in all four systems.

description: Molecular motors power directed transport of cargoes within cells. Even if a single motor is sufficient to transport a cargo, motors often cooperate in small teams. We discuss the cooperative cargo transport by several motors theoretically and explore some of its properties. In particular we emphasize how motor teams can drag cargoes through a viscous environment.

description: ATP synthase's intrinsic molecular electrostatic potential (MESP) adds constructively to, and hence reinforces, the chemiosmotic voltage. This ATP synthase voltage represents a new free energy term that appears to have been overlooked. This term is at least roughly equal in order of magnitude and opposite in sign to the energy needed to be dissipated as a Maxwell's demon (Landauer principle).

Rigidity and Positivity of Mass for Asymptotically Hyperbolic Manifolds

description: The Witten spinorial argument has been adapted in several works over the years to prove positivity of mass in the asymptotically AdS and asymptotically hyperbolic settings in arbitrary dimensions. In this paper we prove a scalar curvature rigidity result and a positive mass theorem for asymptotically hyperbolic manifolds that do not require a spin assumption. The positive mass theorem is reduced to the rigidity case by a deformation construction near the conformal boundary. The proof of the rigidity result is based on a study of minimizers of the BPS brane action.

description: The $B(E2;0^+\to2^+)$ value in $^{68}$Ni has been measured using Coulomb excitation at safe energies. The $^{68}$Ni radioactive beam was post-accelerated at the ISOLDE facility (CERN) to 2.9 MeV/u. The emitted $γ$ rays were detected by the MINIBALL detector array. A kinematic particle reconstruction was performed in order to increase the measured c.m. angular range of the excitation cross section. The obtained value of 2.8$^{+1.2}_{-1.0}$ 10$^2$ e$^2$fm$^4$ is in good agreement with the value measured at intermediate energy Coulomb excitation, confirming the low $0^+\to2^+$ transition probability.

Exchange integrals and magnetization distribution in BaCu2X2O7 (X=Ge,Si)

description: Estimating the intrachain and interchain exchange constants in BaCu2X2O7 (X=Ge,Si) by means of density-functional calculations within the local spin-density approximation (LSDA) we find the Ge compound to be a more ideal realization of a one-dimensional spin chain with Dzyaloshinskii-Moriya interaction than its Si counterpart. Both compounds have a comparable magnitude of interchain couplings in the range of 5-10 K, but the nearest neighbor intrachain exchange of the Ge compound is nearly twice as large as for the Si one. Using the LSDA+U method we predict the detailed magnetization density distribution and especially remarkable magnetic moments at the oxygen sites.
How usable is Galaxy? A usability evaluation of Galaxy

description: Due to its open-source, free, and web-based nature, Galaxy is accessible to a broad range of researchers and users. With Galaxy, complex analyses of large bioinformatic datasets can be performed without the requirement for advanced knowledge in informatics. However, since Galaxy is a highly complex software with a wide range of tools and functionalities, it remains unclear how usable Galaxy is for its target audience. In order to reduce the remaining barriers to use Galaxy (or in other words to improve its usability), we conducted a usability evaluation. Our goal was to find out how usable Galaxy is perceived by its current users, which usability problems occur during a typical use case and how to improve Galaxy's user interface. The evaluation was two-folded: 1) In a quantitative approach, we conducted a questionnaire survey to get a broader view of Galaxy's overall usability and its relationship to other psychological constructs (e.g. feeling of competence). 2) In a qualitative approach, test users were invited to perform typical tasks while using Galaxy and to verbalize their thinking process while conducting the tasks. This think-aloud method enables the researcher to identify major usability issues. All in all, users were comfortable using Galaxy and tend to have a positive attitude towards the software and its features. Nonetheless, some major usability issues exist which were perceived as frustrating by some users (e.g. searching and finding the correct tool for one's own purposes or the presentation of search results). Detailed results and recommendations will be provided in our presentation.
Memory effect of the pp waves with torsion

description: We analyze the motion of test particles in the spacetime of the plane-fronted (pp) waves with torsion in four-dimensions. We conclude that there is a velocity memory effect in the direction of advanced time and along radial direction, while we have rotation of particles in angular direction. The velocity memory effect in the aforementioned directions is severely affected by the value of the tordion mass and probably it is not observable. A very interesting, probably observable effect, stems from the rotation, which is insensitive to the tordion mass.
