description: Repositories can be customized to hold the details of artefacts of many different kinds of research. However, when it comes to the contents of those repositories being exported / shared or exposed to wider infrastructure differences emerge. Whilst STEM outputs are typically well supported, those of other disciplines are often much less well represented and the information in repositories often decays on export, represented in the catch all OTHER. Here we present a challenge for our community from recent experiences, based on practice research, looking at, and calling for engagement on.. how to evolve taxonomies, standards and processes both within repositories and across communities and gatekeeping bodies, discuss our outcomes, and next steps and look to open a wider debate.

description: We obtained Keck/OSIRIS near-IR adaptive optics-assisted integral-field spectroscopy to probe the morphology and kinematics of the ionized gas in four velocity-offset active galactic nuclei (AGNs) from the Sloan Digital Sky Survey. These objects possess optical emission lines that are offset in velocity from systemic as measured from stellar absorption features. At a resolution of ~0.18", OSIRIS allows us to distinguish which velocity offset emission lines are produced by the motion of an AGN in a dual supermassive black hole system, and which are produced by outflows or other kinematic structures. In three galaxies, J1018+2941, J1055+1520 and J1346+5228, the spectral offset of the emission lines is caused by AGN-driven outflows. In the remaining galaxy, J1117+6140, a counterrotating nuclear disk is observed that contains the peak of Pa$α$ emission 0.2" from the center of the galaxy. The most plausible explanation for the origin of this spatially and kinematically offset peak is that it is a region of enhanced Pa$α$ emission located at the intersection zone between the nuclear disk and the bar of the galaxy. In all four objects, the peak of ionized gas emission is not spatially coincident with the center of the galaxy as traced by the peak of the near-IR continuum emission. The peaks of ionized gas emission are spatially offset from the galaxy centers by 0.1"-0.4" (0.1-0.7 kpc). We find that the velocity offset originates at the location of this peak of emission, and the value of the offset can be directly measured in the velocity maps. The emission-line ratios of these four velocity-offset AGNs can be reproduced only with a mixture of shocks and AGN photoionization. Shocks provide a natural explanation for the origin of the spatially and spectrally offset peaks of ionized gas emission in these galaxies.

description: Recent \emph{in vivo} experiments have illustrated the importance of understanding the hemodynamics of heart morphogenesis. In particular, ventricular trabeculation is governed by a delicate interaction between hemodynamic forces, myocardial activity, and morphogen gradients, all of which are coupled to genetic regulatory networks. The underlying hemodynamics at the stage of development in which the trabeculae form is particularly complex, given the balance between inertial and viscous forces. Small perturbations in the geometry, scale, and steadiness of the flow can lead to changes in the overall flow structures and chemical morphogen gradients, including the local direction of flow, the transport of morphogens, and the formation of vortices. The immersed boundary method was used to solve the fluid-structure interaction problem of fluid flow moving through a two chambered heart of a zebrafish (\emph{Danio rerio}), with a trabeculated ventricle, at $96\ hpf$ (hours post fertilization). Trabeculae heights and hematocrit were varied, and simulations were conducted for two orders of magnitude of Womersley number, extending beyond the biologically relevant range ($0.2$ -- $12.0$). Both intracardial and intertrabecular vortices formed in the ventricle for biologically relevant parameter values. The bifurcation from smooth streaming flow to vortical flow depends upon the trabeculae geometry, hematocrit, and $Wo$. This work shows the importance of hematocrit and geometry in determining the bulk flow patterns in the heart at this stage of development.

description: Episciences is a platform to publish diamond open access overlay journals. The ambition is to provide the scientific communities with the technical means to produce high quality journals, at an efficient cost, compliant by design with FAIR principles. The process relies on open repositories (arXiv ; Zenodo ; HAL ; CWI). The presentation will explain how Episciences overcame the limitations of its previous metadata ingestion model and leveraged the services of open scientific infrastructures. In this regard, we have also implemented the COAR notification protocol and the "Signposting the Scholarly Web" approach that allow us to efficiently exchange information with compatible open repositories like HAL. This allows us to offer them enriched metadata in turn. We will conclude by explaining why our metadata enrichment methodology should ideally evolve in the future to be also based on the Notify/Linked Data Notification approach, as soon as other COAR Notify compatible platforms or repositories appear.

Gluon TMDs in quarkonium production

Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Quarkonium production offers good possibilities to study gluon TMDs. In this proceedings contribution this topic is explored for the linearly polarized gluons inside unpolarized hadrons and unpolarized gluons inside transversely polarized hadrons. It is argued that $χ_{b0/2}$ and $η_b$ production at LHC are best to study the effects of linearly polarized gluons in hadronic collisions, by means of angular independent ratios of ratios of cross sections. This can be directly compared to $\cos 2ϕ$ asymmetries in heavy quark pair and dijet production in DIS at a future high-energy Electron-Ion Collider (EIC), which probe the same TMDs. In the small-$x$ limit this corresponds to the Weizsäcker-Williams (WW) gluon distributions, which should show a change in behavior for transverse momenta around the saturation scale. Together with investigations of the dipole (DP) gluon distributions, this can provide valuable information about the polarization of the Color Glass Condensate if sufficiently small $x$ are reached. Quarkonia can also be useful in the study of single transverse spin asymmetries. For transversely polarized hadrons the gluon distribution can be asymmetric, which is referred to as the Sivers effect. It leads to single spin asymmetries in for instance $J/ψ$ (pair) production at AFTER@LHC, which probe the WW or $f$-type gluon Sivers TMD. It allows for a test of a sign-change relation w.r.t. the gluon Sivers TMD probed at an EIC in open heavy quark pair production. Single spin asymmetries in backward inclusive $C$-odd quarkonium production, such as $J/ψ$ production, may offer probes of the DP or $d$-type gluon Sivers TMD at small $x$-values in the polarized proton, which in that limit corresponds to a correlator of a single Wilson loop, describing the spin-dependent odderon.

description: UNIZULU is one of the oldest higher learning institutions with history in research. Based on its location, it serves unique and different research purposes as compared to other institutions that are in more developed areas of the country. This study aims to discover the relationship between the content creators that are affiliated to the institution and the availability of this content to the UNIZULU affiliated consumers. This investigation is motivated by the sums of money that the academic libraries pay to different academic service providers from different part of the world with the aim of serving relevant information needs to the academic community. According to Mavhunga Clapperton (2018) many of African higher education curricula still follow the disciplinary structures of colonialism that were set by for economic exploitation. To address these issues, academic institutions need to serve relevant content by prioritizing locally produced research that seek to bridge the splits between academic disciplines, producers of knowledge and end-users. Buntu (2013) testifies Africa is overloaded with irrelevant knowledge that disarms rather than empowers individuals and communities. This means the information that is being sourced and served to the consumers do not address the societal issues that surround communities.

description: Although black holes are eminent manifestations of very strong gravity, the geometry of space-time around and even inside them can be significantly affected by additional bodies present in their surroundings. We study such an influence within static and axially symmetric (electro-)vacuum space-times described by exact solutions of Einstein's equations, considering astrophysically motivated configurations (such as black holes surrounded by rings) as well as those of pure academic interest (such as specifically "tuned" systems of multiple black holes). The geometry is represented by the simplest invariants determined by the metric (the lapse function) and its gradient (gravitational acceleration), with special emphasis given to curvature (the Kretschmann and Ricci-square scalars). These quantities are analyzed and their level surfaces plotted both above and below the black-hole horizons, in particular near the central singularities. Estimating that the black hole could be most strongly affected by the other black hole, we focus, in this first paper, on the Majumdar--Papapetrou solution for a binary black hole and compare the deformation caused by "the other" hole (and the electrostatic field) with that induced by rotational dragging in the well-known Kerr and Kerr--Newman solutions.

description: Much of the inner Milky Way's (MW) global rotation and velocity dispersion patterns can be reproduced by models of secularly-evolved, bar-dominated bulges. More sophisticated constraints, including the higher moments of the line-of-sight velocity distributions (LOSVDs) and limits on the chemodynamical substructure, are critical for interpreting observations of the unresolved inner regions of extragalactic systems and for placing the MW in context with other galaxies. Here, we use SDSS-APOGEE data to develop these constraints, by presenting the first maps of the LOSVD skewness and kurtosis of metal-rich and metal-poor inner MW stars (divided at [Fe/H] = -0.4), and comparing the observed patterns to those that are seen both in N-body models and in extragalactic bars. Despite closely matching the mean velocity and dispersion, the models do not reproduce the observed LOSVD skewness patterns in different ways, which demonstrates that our understanding of the detailed orbital structure of the inner MW remains an important regime for improvement. We find evidence in the MW of the skewness-velocity correlation that is used as a diagnostic of extragalactic bar/bulges. This correlation appears in metal-rich stars only, providing further evidence for different evolutionary histories of chemically differentiated populations. We connect these skewness measurements to previous work on high-velocity "peaks" in the inner Galaxy, confirming the presence of that phenomenon, and we quantify the cylindrical rotation of the inner Galaxy, finding that the latitude-independent rotation vanishes outside of lon ~ 7 deg. Finally, we evaluate the MW data in light of select extragalactic bar diagnostics and discuss progress and challenges of using the MW as a resolved analog of unresolved stellar populations.

Blazar flares powered by plasmoids in relativistic reconnection

description: Powerful flares from blazars with short ($\sim$ min) variability timescales are challenging for current models of blazar emission. Here, we present a physically motivated ab initio model for blazar flares based on the results of recent particle-in-cell (PIC) simulations of relativistic magnetic reconnection. PIC simulations demonstrate that quasi-spherical plasmoids filled with high-energy particles and magnetic fields are a self-consistent by-product of the reconnection process. By coupling our PIC-based results (i.e., plasmoid growth, acceleration profile, particle and magnetic content) with a kinetic equation for the evolution of the electron distribution function we demonstrate that relativistic reconnection in blazar jets can produce powerful flares whose temporal and spectral properties are consistent with the observations. In particular, our model predicts correlated synchrotron and synchrotron self-Compton flares of duration of several hours--days powered by the largest and slowest moving plasmoids that form in the reconnection layer. Smaller and faster plasmoids produce flares of sub-hour duration with higher peak luminosities than those powered by the largest plasmoids. Yet, the observed fluence in both types of flares is similar. Multiple flares with a range of flux-doubling timescales (minutes to several hours) observed over a longer period of flaring activity (days or longer) may be used as a probe of the reconnection layer's orientation and the jet's magnetization. Our model shows that blazar flares are naturally expected as a result of magnetic reconnection in a magnetically-dominated jet.

description: Most academic institutions are increasingly required to take responsibilities for the visibility and impact of their scholarly research out-put, which is progressively facilitated through open access repositories platforms, and practices associated with open access initiatives such as digital repositories. It is believed that, research outputs openly available, increases global visibility that will not only lead to wider accessibility but also making a greater contribution to the national development. The study examines the visibility of UNAM digital repositories on a digital global space. Fifty (50) resources from UNAM library's digital repositories were randomly selected; a thorough review search of these 50 selected digital resources was done using the five (5) commonly used search engines (Google, Yahoo, Badu, Yandex and Bing. Various logics and keywords from subject areas was used in the search. The result show that most of UNAM digital repositories resources were likely discovered through google and little to none were discovered on the remaining search engines. Repository managers and librarians, presentation will cover the following central themes: digital repositories in general, happenings in Africa and in the Namibian context focusing on UNAM; the use of search engines to discover resources; and operational status of the digital repositories at UNAM.

description: Crystal plasticity occurs by deformation bursts due to the avalanche-like motion of dislocations. Here we perform extensive numerical simulations of a three-dimensional dislocation dynamics model under quasistatic stress-controlled loading. Our results show that avalanches are power-law distributed, and display peculiar stress and sample size dependence: The average avalanche size grows exponentially with the applied stress, and the amount of slip increases with the system size. These results suggest that intermittent deformation processes in crystalline materials exhibit an extended critical-like phase in analogy to glassy systems, instead of originating from a non-equilibrium phase transition critical point.

description: A strategy is developed for generating equilibrated high molecular-weight polymer melts described with microscopic detail by sequentially backmapping coarse-grained (CG) configurations. The microscopic test model is generic but retains features like hard excluded volume interactions and realistic melt densities. The microscopic representation is mapped onto a model of soft spheres with fluctuating size, where each sphere represents a microscopic subchain with $N_{\rm b}$ monomers. By varying $N_{\rm b}$ a hierarchy of CG representations at different resolutions is obtained. Within this hierarchy, CG configurations equilibrated with Monte Carlo at low resolution are sequentially fine-grained into CG melts described with higher resolution. A Molecular Dynamics scheme is employed to slowly introduce the microscopic details into the latter. All backmapping steps involve only local polymer relaxation thus the computational efficiency of the scheme is independent of molecular weight, being just proportional to system size. To demonstrate the robustness of the approach, microscopic configurations containing up to $n=1000$ chains with polymerization degrees $N=2000$ are generated and equilibration is confirmed by monitoring key structural and conformational properties. The extension to much longer chains or branched polymers is straightforward.

description: The collapse of a polyelectrolyte gel in a (monovalent) salt solution is analysed using a new model that includes interfacial gradient energy to account for phase separation in the gel, finite elasticity and multicomponent transport. We carry out a linear stability analysis to determine the stable and unstable spatially homogeneous equilibrium states and how they phase separate into localized regions that eventually coarsen to a new stable state. We then investigate the problem of a collapsing gel as a response to increasing the salt concentration in the bath. A phase space analysis reveals that the collapse is obtained by a front moving through the gel that eventually ends in a new stable equilibrium. For some parameter ranges, these two routes to gel shrinking occur together.

institutional repository search engine performance
user experience
mobile device accessibility

description: The Repository Analytics and Metrics Portal (RAMP) is a web service that aggregates Google search engine performance metrics for a global set institutional repositories. A previously reported analysis of the open RAMP dataset, conducted in 2019, demonstrated a disparity in IR access between the global north and south and suggested that a key driver of this disparity is the different types of devices used to search for and access IR content. Specifically, users from the global south are more likely than their global north counterparts to interact with IR content using smaller, handheld mobile devices. This finding has implications for the design of accessible user interfaces across IR platforms. We present updated findings using the complete RAMP dataset of 2019-2021 search engine performance data for a larger set of IR. Methods for cleaning and augmenting RAMP data will be presented, and trends demonstrating the continued disparity of IR access between the global north and south throughout the COVID-19 pandemic will be highlighted. We will provide recommendations for improving the accessibility of IR content for mobile devices, with a closing discussion of other factors that may inhibit access to IR content by users within the global south.

description: Graphene based photo-detecting has received great attentions and the performance of such detector is stretching to both ends of high sensitivity and ultra-fast response. However, limited by the current photo-gating mechanism, the price for achieving ultra-high sensitivity is sacrificing the response time. Detecting weak signal within short response time is crucial especially in applications such as optical positioning, remote sensing, and biomedical imaging. In this work, we bridge the gap between ultra-fast response and ultra-high sensitivity by employing a graphene/SiO2/lightly-doped-Si architecture with revolutionary interfacial gating mechanism. Such device is capable to detect < 1 nW signal (with responsivity of ~1000 A W-1) and the spectral response extends from visible to near-infrared. More importantly, the photoresponse time of our device has been pushed to ~400 ns. The current device structure does not need complicated fabrication process and is fully compatible with the silicon technology. This work will not only open up a route to graphene-based high performance optoelectronic devices, but also have great potential in ultra-fast weak signal detection.

description: In this letter we describe how we use stellar dynamics information to constrain the shape of the stellar IMF in a sample of 27 early-type galaxies from the CALIFA survey. We obtain dynamical and stellar mass-to-light ratios, $Υ_\mathrm{dyn}$ and $Υ_{\ast}$, over a homogenous aperture of 0.5~$R_{e}$. We use the constraint $Υ_\mathrm{dyn} \ge Υ_{\ast}$ to test two IMF shapes within the framework of the extended MILES stellar population models. We rule out a single power law IMF shape for 75% of the galaxies in our sample. Conversely, we find that a double power law IMF shape with a varying high-mass end slope is compatible (within 1$σ$) with 95% of the galaxies. We also show that dynamical and stellar IMF mismatch factors give consistent results for the systematic variation of the IMF in these galaxies.

description: Stellar scattering off irregularities in a galaxy disk has been shown to make an exponential radial profile, but no fundamental reason for this has been suggested. Here we show that exponentials are mathematically expected from random scattering in a disk when there is a slight inward bias in the scattering probability. Such a bias was present in our previous scattering experiments that formed exponential profiles. Double exponentials can arise when the bias varies with radius. This is a fundamental property of scattering and may explain why piece-wise exponential profiles are ubiquitous in galaxies, even after minor mergers and other disruptive events.

description: As the scale of research data increases, both in the size and number of files, it becomes increasingly challenging to curate and deposit in a data repository for long term access and reuse. Managing and curating large datasets can be especially challenging for data repositories that aim to make the data they host accessible and useful to a wide range of users. Publishing and archiving large research data often requires creative combinations of curation and technical strategies to successfully create datasets that are as FAIR as possible and meet the needs of diverse research communities. In this presentation from Harvard Dataverse, speakers will present three large curation projects in order to discuss the opportunities and challenges presented by big data for an open, generalist research data repository.

The Role of H2O and O2 Molecules and Phosphorus Vacancies in the Structure Instability of Phosphorene

description: The poor structural stability of phosphorene in air was commonly ascribed to humidity and oxygen molecules. Recent exfoliation of phosphorene in deoxygenated water promotes the need to re-examine the role of H2O and O2 molecules. Considering the presence of high population of vacancies in phosphorene, we investigate the interaction of H2O and O2 molecules with vacancy-contained phosphorene using first-principles calculations. In contrast to the common notion that physisorbed molecules tend to have a stronger adsorption at vacancy sites, we show that H2O has nearly the same adsorption energy at the vacancy site as that at the perfect one. Charge transfer analysis shows that O2 is a strong electron scavenger, which transfers the lone-pair electrons of the phosphorus atoms to the 2π* antibonding orbital of O2. As a result, the barrier for the O-O bond splitting to form O-P bonds is reduced from 0.81 eV at the perfect site to 0.59 eV at the defect site, leading to an about 5000 faster oxidizing rate at the defect site than at the perfect site at room temperature. Hence, our work reveals that the vacancy in phosphorene shows a stronger oxygen affinity than the perfect phosphorene lattice site. Structural degradation of phosphorene due to oxidization may occur rapidly at edges and grain boundaries where vacancies tend to agglomerate.

description: Research Object Crate (RO-Crate) is a community effort and specification to practically achieve FAIR packaging of research objects (digital objects like data, methods, software) with structured metadata and context. RO-Crate uses well-established Web standards and FAIR principles. For common metadata representations, RO-Crate builds on schema.org, a mature and general mark-up vocabulary used by search engines, including Google Dataset Search. RO-Crate is adopted by many research projects as a pragmatic implementation of the FAIR principles that can be both general for interoperable exchange and extensible for domain-specific archiving. RO-Crate development began in early 2019, when a workshop at Open Repositories 2019 in Hamburg generated a significant number of use-cases and expressions of interest from the OR community. This presentation will introduce RO-Crate, its continuing development and rapid adoption since 2019, report on how it is now being used in repository software, and the potential for further use in repository platforms that will be familiar to OR attendees.
