description: We extend the Gyulassy-Levai-Vitev reaction operator approach to multiple elastic scattering of fast partons traversing dense nuclear matter to take into account the leading power corrections due to the medium recoil and to derive the change in the partons' longitudinal momentum.We employ a boost-invariant formalism to generalize previous treatments of the problem, which were specific to the target rest frame. We apply the transverse momentum diffusion results in a simple analytic model to evaluate the broadening of the back-to-back di-hadron correlation function in $d+Au$ reactions.

description: Blue Stragglers are stars located in an unexpected region of the color-magnitude diagram of a stellar population, as they appear bluer and more luminous than the stars in the turnoff region. They are ubiquitous, since they have been found among Milky Way field stars, in open and globular clusters, and also in other galaxies of the Local Group. Here we present a study on the blue straggler population of the old and metal-rich open cluster Collinder 261, based on Gaia DR2 data and on a multi-epoch radial velocity survey conducted with FLAMES@VLT. We also analyze the radial distribution of the blue straggler population to probe the dynamical status of the cluster. Blue straggler candidates were identified first with Gaia DR2, according to their position on the CMD, proper motions, and parallaxes. Their radial distribution was compared with those of the main sequence, red giant, and red clump stars, to evaluate mass segregation. Additionally, their radial velocities (and the associated uncertainties) were compared with the mean radial velocity and the velocity dispersion of the cluster. When possible, close binaries and long-period binaries were also identified, based on the radial velocity variations for the different epochs. We also looked for yellow stragglers, i.e., possible evolved blue stragglers. We found 53 blue stragglers members of Collinder 261, six of them already identified in previous catalogs. Among the blue straggler candidates with radial velocity measurements, we found one long-period binary, five close-binary systems, three non-variable stars; we also identified one yellow straggler.

description: The color dipole approach has been applied in the target rest frame to address the issues of transverse momentum broadening and energy loss of a fast quark propagating in the nuclear medium. A recent application of the theory to the FermiLab E772/E866 experimental data, determining the rate of energy loss of a quark propagating in the medium to be 2 to 3 GeV/fm, will be reviewed. Calculations for the transverse momentum distribution will be presented, and the results will be compared to the E866 data. The theory will be shown to compare favorably to the data, and these results will be shown to suggest that the momentum broadening of a quark is about twice the generally accepted size.

description: A notion of local algebras is introduced in the theory of causal fermion systems. Their properties are studied in the example of the regularized Dirac sea vacuum in Minkowski space. The commutation relations are worked out, and the differences to the canonical commutation relations are discussed. It is shown that the spacetime point operators associated to a Cauchy surface satisfy a time slice axiom. It is proven that the algebra generated by operators in an open set is irreducible as a consequence of Hegerfeldt's theorem. The light cone structure is recovered by analyzing expectation values of the operators in the algebra in the limit when the regularization is removed. It is shown that every spacetime point operator commutes with the algebras localized away from its null cone, up to small corrections involving the regularization length.

multi-sensor image fusion

monitoring system

description: Current technology in imaging sensors offers a wide variety of information that can be extracted from
 an observed scene. Acquired images from different sensor modalities exhibit diverse characteristics such as type
 of degradation; salient features etc. and can be particularly beneficial in surveillance systems. Such representative
 sensory systems include infrared and thermal imaging cameras, which can operate beyond the visual spectrum
 providing functionality under any environmental conditions. Multi-sensor information is jointly combined to pro-
 vide an enhanced representation, particularly utile in automated surveillance systems such as monitoring robotics.
 In this chapter, a surveillance framework based on a fusion model is presented in order to enhance the capabilities
 of unmanned vehicles for monitoring critical infrastructures. The fusion scheme multiplexes the acquired repre-
 sentations from different modalities by applying an image decomposition algorithm and combining the resulted
 sub-signals via metric optimization. Subsequently, the fused representations are fed into an identification module
 in order to recognize the detected instances and improve eventually the surveillance of the required area. The
 proposed framework adopts recent advancements in object detection for optimal identification by deploying a deep
 learning model properly trained with fused data. Initial results indicate that the overall scheme can accurately
 identify the objects of interest by processing the enhanced representations of the fusion scheme. Considering that
 the overall processing time and the resource requirements are kept in low levels, the framework can be integrated
 in an automated surveillance system comprised by unmanned vehicles.

description: Data ownership and management policies can affect how research data are supported at a university. This Pecha Kucha presentation will highlight the preliminary results of our current research on university data ownership and management policies. In contrast to previous studies on institutional data management policies, we examined the university websites of 206 institutions with a Carnegie Classification on Institutions of Higher Education of either "High" or "Very High" research level as of July 2014. Some of the major questions we asked included: Does the institution have a data sharing or management policy? What does the policy cover? Who owns the policy (e.g. Office of Research, Information Technology, Libraries)? What happens to the ownership of the data if a researcher leaves the institution? Are universities with data management services provided by the library more likely to have a policy on data management? Ultimately, our goal is to determine if universities support data management comprehensively with complementary policies and services. The topics that will be covered include data stewardship, ownership, retention, and sharing in regards to university research data policies.

description: Since the development of the space program, we as a species have experienced environments beyond Earth. We’ve seen astronauts standing on unfamiliar terrain while looking back at our home planet. From this point on access to the solar system had been opened, only leaving time and will to decide when humans would journey further. More than half a century has passed since the first moonwalk, yet NASA is only now attempting to travel back to the moon. Private entities have begun to fill this gap, pushing humanity to begin the future. This highly fictional fantasy is seemingly being forced into reality by several dreamers. While NASA has developed the Artemis program, Space X has developed Starship. A launch vehicle capable of bringing humans to the red planet and beyond. With such forceful innovation in the field of rocketry the possibility of Martian settlement seems all but certain, opening an entirely new realm of possibilities within the fields of engineering and architecture. Although if architects don’t quickly accept and engage in this field, the consequences to themselves could become dire. Because Mars is so far away, communication quickly becomes a problem, with delays of up to 46 minutes. This all but forces construction to be automated using robotics. Additionally, resources are not readily available on Mars, they need to be mined and processed to extract the materials needed for construction. The combination of these two problems means that a lightweight, robotically operable material is needed to construct the initial structures on the planet. Fabrics are the prime choices for this task as they are flexible and lightweight. Lessons can be learned through the long history of textile architecture on Earth and be applied using a similar method on Mars. Historical, Modern, and Robotic methods have been researched to further determine what sticks and what does not. The lightweight, flexible, manipulable nature of fabrics combine to create a design approach that best suits the Martian environment. As nomadic peoples have moved and survived in the harshest environments on Earth using fabrics, so should humans on mars.

description: In this paper we examine the electronic and geometrical structure of impurity-vacancy complexes in Si and Ge. Already Watkins suggested that in Si the pairing of Sn with the vacancy produces a complex with the Sn-atom at the bond center and the vacancy split into two half vacancies on the neighboring sites. Within the framework of density-functional theory we use two complementary ab initio methods, the pseudopotential plane wave (PPW) method and the all-electron Kohn-Korringa-Rostoker (KKR) method, to investigate the structure of vacancy complexes with 11 different sp-impurities. For the case of Sn in Si, we confirm the split configuration and obtain good agreement with EPR data of Watkins. In general we find that all impurities of the 5sp and 6sp series in Si and Ge prefer the split-vacancy configuration, with an energy gain of 0.5 to 1 eV compared to the substitutional complex. On the other hand, impurities of the 3sp and 4sp series form a (slightly distorted) substitutional complex. Al impurities show an exception from this rule, forming a split complex in Si and a strongly distorted substitutional complex in Ge. We find a strong correlation of these data with the size of the isolated impurities, being defined via the lattice relaxations of the nearest neighbors.

description: In the present study the stress transfer mechanism in graphene-polymer systems under tension is examined experimentally using the technique of laser Raman microscopy. We discuss in detail the effect of graphene edge geometry, lateral size and thickness which need to be taken under consideration when using graphene as a protective layer. The systems examined comprised of graphene flakes with large length (over ~50 microns) and thickness of one to three layers simply deposited onto PMMA substrates which were then loaded to tension up to ca. 1.60% strain. The stress transfer profiles were found to be linear while the results show that large lateral sizes of over twenty microns are needed in order to provide effective reinforcement at levels of strain higher than 1%. Moreover, the stress-built up has been found to be quite sensitive to both edge shape and geometry of the loaded flake. Finally, the transfer lengths were found to increase with the increase of graphene layers. The outcomes of the present study provide crucial insight on the issue of stress transfer from polymer to nano-inclusions as a function of edge geometry, lateral size and thickness in a number of applications.

description: We study the mechanism responsible for the onset of instabilities in a chiral phase transition at nonzero temperature and baryon chemical potential. As a low-energy effective model, we consider an expanding relativistic plasma of quarks coupled to a chiral field, and obtain a phenomenological chiral hydrodynamics from a variational principle. Studying the dispersion relation for small fluctuations around equilibrium, we identify the role played by chiral waves and pressure waves in the generation of instabilities. We show that pressure modes become unstable earlier than chiral modes.

description: The RDA Metadata Standards WG (MSWG) is comprised of individuals and organizations involved in the development, implementation, and use of metadata for scientific data. The continued proliferation and abundance of content driven metadata standards for scientific data present significant challenges for individuals seeking guidance in the selection of appropriate metadata standards and automatic processing capabilities for manipulating digital data. A collaborative, open directory of metadata standards applicable to scientific data can help address these challenges. A directory listing metadata standards applicable to research data will be of tremendous benefit to the global community facing data management challenges. Previous efforts provide evidence of this need, although these undertakings were not intended to be collective, sustainable directories. Discipline-specific metadata efforts have led to duplicative work because of the lack of communication across communities. The RDA Metadata Directory can begin to address these limitations. The RDA's global platform and cross-disciplinary reach, combined with the capacity to leverage social technology, can support the development of a community-driven and sustainable RDA Metadata Directory. This presentation will demonstrate the latest version of the MSWG prototype directory and discuss the use cases collected for the various ways this directory can be used.

description: A Data Type Registry provides a way to easily register detailed and structured descriptions of data that can range from simple single value elements up to complex multi-dimensional scientific datasets. The benefits of registration include enabling those who did not create a given instance of typed data to understand and potentially reuse it, to encourage others to use established data types in their own data collections and analysis efforts, and to build services and applications that could be applied to standardized data types. This presentation will focus on the need for and advantages of Data Type Registries and will provide a demonstration of the latest version of a registry prototype.

description: We study the presence of resonances in the region of space around the Earth. We consider a massless body (e.g, a dust particle or a small space debris) subject to different forces: the gravitational attraction of the geopotential, the effects of Sun and Moon. We distinguish different types of resonances: tesseral resonances are due to a commensurability involving the revolution of the particle and the rotation of the Earth, semi-secular resonances include the rates of variation of the mean anomalies of Moon and Sun, while secular resonances just depend on the rates of variation of the arguments of perigee and the longitudes of the ascending nodes of the perturbing bodies. We characterize such resonances, giving precise statements on the regions where the resonances can be found and provide examples of some specific commensurability relations.

description: In this paper, we propose a feasible scheme for generating the Schrödinger cat states of a macroscopic mechanical resonator in pulsed cavity optomechanics. Starting with cooling the mechanical oscillator to its ground state, a red and a blue pulses with different powers are simultaneously employed to drive the cavity to achieve squeezed mechanical states. Subsequently, a second red pulse is utilized to generate the macroscopic mechanical quantum superpositions, conditioned on the detection of cavity output photons. Finally, after being stored in the resonator for a period of time, the mechanical state is mapped, with a third red pulse, to the cavity output field used for state verification. Our approach is generic and can also be used to produce other kinds of non-Gaussian mechanical states, like optical-catalysis nonclassical states.

description: Social play is a highly rewarding and motivated behaviour displayed by juveniles of many mammalian species. We hypothesized that the orexin/hypocretin (ORX) system is involved in the expression of juvenile social play behaviour because this system is interconnected with brain regions that comprise the social behaviour and mesocorticolimbic reward networks. We found that exposure to social play increased recruitment of ORX-A neurons in juvenile rats. Furthermore, central administration of ORX-A decreased social play duration, while central blockade of ORX-1 receptors differentially altered social play duration in juvenile rats with low versus high baseline levels of social play (increasing social play in low baseline social play individuals and decreasing social play in high baseline social play individuals).

description: Some cosmological scenarios with bulk viscosity for the dark energy fluid are considered. Based on some considerations related to hydrodynamics, two different equations of state for dark energy are assumed, leading to power-law and logarithmic effective corrections to the pressure. The models are tested with the latest astronomical data from Type Ia supernovae (Pantheon sample), measurements of the Hubble parameter $H(z)$, Baryon Acoustic Oscillations and Cosmic Microwave Background radiation. In comparison with $Λ$CDM model, some different results are obtained and their viability is discussed. The power-law model shows some modest results, achieved under negative values of bulk viscosity, while the logarithmic scenario provide good fits in comparison to $Λ$CDM model.

description: Specialist species thriving under specific environmental conditions in narrow geographic ranges are widely recognised as heavily threatened by climate deregulation. Many might rely on both their potential to adapt and to disperse toward a refugium to avoid extinction. It is thus crucial to understand the influence of environmental conditions on the unfolding process of adaptation. Here, I study the eco-evolutionary dynamics of a sexually reproducing specialist species in a two-patch quantitative genetic model with moving optima. Thanks to a separation of ecological and evolutionary time scales and the phase-line study of the selection gradient, I derive the critical environmental speed for persistence, which reflects how the existence of a refugium impacts extinction patterns and how it relates to the cost of dispersal. Moreover, the analysis provides key insights about the dynamics that arise on the path towards this refugium. I show that after an initial increase of population size, there exists a critical environmental speed above which the species crosses a tipping point, resulting into an abrupt habitat switch. In addition, when selection for local adaptation is strong, this habitat switch passes through an evolutionary "death valley", leading to a phenomenon related to evolutionary rescue, which can promote extinction for lower environmental speeds than the critical one.
Transparent Nuclei and Deuteron-Gold Collisions at RHIC

description: The current normalization of the cross section of inclusive high-pT particle production in deuteron-gold collisions measured RHIC relies on Glauber calculations for the inelastic d-Au cross section. These calculations should be corrected for diffraction. Moreover, they miss the Gribov's inelastic shadowing which makes nuclei more transparent (color transparency). The magnitude of this effect rises with energy and it may dramatically affect the normalization of the RHIC data. We evaluate these corrections employing the light-cone dipole formalism and found a rather modest corrections for the current normalization of the d-Au data. The results of experiments insensitive to diffraction (PHENIX, PHOBOS) should be renormalized by about 20% down, while those which include diffraction (STAR), by only 10%. Such a correction completely eliminates the Cronin enhancement in the PHENIX data for pions. The largest theoretical uncertainty comes from the part of the inelastic shadowing which is related to diffractive gluon radiation, or gluon shadowing. Our estimate is adjusted to data for the triple-Pomeron coupling, however, other models do not have such a restrictions and predict much stronger gluon shadowing. Therefore, the current data for high-pT hadron production in d-Au collisions at RHIC cannot exclude in a model independent way the possibility if initial state suppression proposed by Kharzeev-Levin-McLerran. Probably the only way to settle this uncertainty is a direct measurement of the inelastic d-Au cross sections at RHIC. Also d-Au collisions with a tagged spectator nucleon may serve as a sensitive probe for nuclear transparency and inelastic shadowing. We found an illuminating quantum-mechanical effect: the nucleus acts like a lens focusing spectators into a very narrow cone.

Queering Vatican City: a reinterpretation of the catholic church
Creators: name: Milton, Reece
Publisher: name: The University of British Columbia
Year: 2023

description: This thesis investigates subversive forms of public and private space emerging from queer theory and disability discourse. In defining queer space (which is subject to change over time and person), this thesis looks at several case studies of architectural intervention done by and for queer people, and extrapolates their qualities. In describing queer space a subversion of heteronormative spaces, the proposed site for intervention is Vatican City, the global headquarters for the Roman Catholic Church, an powerful institution responsible for oppression of queer people. This project seeks to subvert the dominion and shame imposed by the hetero-patriarchal catholic church by suggesting Christ is queer, and that the religion should be based around queerness. A sequence of divine interventions of existing spatial elements at multiple scales demonstrates the queer future we hope for.

description: We have surveyed the metal-rich spiral galaxy M83 (NGC5236) for its Wolf-Rayet population using VLT-FORS2 narrow-band imaging and follow-up spectroscopy. From a total of 280 candidates identified using HeII 4686 imaging, Multi Object Spectroscopy of 198 sources was carried out, revealing 132 objects containing bona-fide Wolf-Rayet features. From this sample, an exceptional W-R content of 1030 is inferred, with N(WC)/N(WN)=1.3, continuing the trend to larger values at higher metallicity amongst Local Group galaxies. More dramatic is the dominance of late-type WC stars in M83 with N(WC8-9)/N(WC4-7)=9 which we attribute to the sensitivity of the classification line CIII 5696 to mass-loss, providing the strength of WC winds scale with metallicity. One young massive compact cluster, #74 in our catalogue, hosts 20% of the entire galactic population, namely 180 late WC stars and 50 late WN stars.

description: Computer-actionable policies are used to enforce management, automate administrative tasks, validate assessment criteria, and automate scientific analyses. The benefits of using policies include minimization of the amount of labor needed to manage a collection, the ability to publish to the users the rules that are being used, and the ability to automate process management. Currently scientific communities use their own sets of policies, if any. A generic set of policies that can be revised and adapted by user communities and site managers who need to build up their own data collection in a trusted environment does not exist. Thus, the goals of the working group are to bring together practitioners in policymaking and policy implementation; to identify typical application scenarios for policies such as replication, preservation, etc.; to collect and to register practical policies; and to enable sharing, revising, adapting, and reuse of computer-actionable policies. This presentation will provide an overview of the working group and its activities, including a recent survey to elicit the types of policies currently being enforced as well as policy areas considered to be the most important.

description: A key principle in assessing textual similarity is measuring the degree of semantic overlap between two texts by considering the word alignment. Such alignment-based approaches are intuitive and interpretable; however, they are empirically inferior to the simple cosine similarity between general-purpose sentence vectors. To address this issue, we focus on and demonstrate the fact that the norm of word vectors is a good proxy for word importance, and their angle is a good proxy for word similarity. Alignment-based approaches do not distinguish them, whereas sentence-vector approaches automatically use the norm as the word importance. Accordingly, we propose a method that first decouples word vectors into their norm and direction, and then computes alignment-based similarity using earth mover's distance (i.e., optimal transport cost), which we refer to as word rotator's distance. Besides, we find how to grow the norm and direction of word vectors (vector converter), which is a new systematic approach derived from sentence-vector estimation methods. On several textual similarity datasets, the combination of these simple proposed methods outperformed not only alignment-based approaches but also strong baselines.

description: The spin Coulomb drag effect, arising from the exchange of momentum between electrons of opposite spins, plays a crucial role in the spin transport of interacting electron systems and can be characterized by the exchange-correlation (XC) kernel in the spin channel $K_{\rm XC}^-(q,ω)$. Using the state-of-the-art Variational Diagrammatic Monte Carlo approach, we compute the Matsubara-frequency-resolved spin XC kernel $K_{\rm XC}^-(q,iω_n)$ for the three-dimensional uniform electron gas at sufficiently low temperatures with high precision. In the long-wavelength limit, we identified a singular behavior of the form $A(iω_n)/q^2$, confirming the theoretically predicted ultranonlocal behavior associated with spin Coulomb drag. Analysis of this structure in the low frequency region enables precise determination of two crucial parameters characterizing the spin Coulomb drag effect: the spin mass enhancement factor and spin diffusion relaxation time. We observe a significant trend of increasing enhancement of the spin mass factor with decreasing electron density, and provide clear evidence for the suppression of spin diffusion at low temperatures. These quantitative findings advance our understanding of Coulomb interaction effects on spin transport and provide essential parameters for time-dependent density functional theory and spintronics applications.
