description: With two directly detected protoplanets, the PDS 70 system is a unique source in which to study the complex interplay between forming planets and their natal environment. The large dust cavity carved by the two giant planets can affect the disk chemistry, and therefore the molecular emission morphology. On the other hand, chemical properties of the gas component of the disk are expected to leave an imprint on the planetary atmospheres. In this work, we reconstruct the emission morphology of a rich inventory of molecular tracers in the PDS 70 disk, and we look for possible chemical signatures of the two actively accreting protoplanets, PDS b and c. We leverage Atacama Large Millimeter/submillimeter Array (ALMA) band 6 high-angular-resolution and deep-sensitivity line emission observations, together with image and $uv$-plane techniques, to boost the detection of faint lines. We robustly detect ring-shaped emission from $^{12}$CO, $^{13}$CO, C$^{18}$O, H$^{13}$CN, HC$^{15}$N, DCN, H$_2$CO, CS, C$_2$H, and H$^{13}$CO$^{+}$ lines in unprecedented detail. Most of the molecular tracers show a peak of the emission inside the millimeter dust peak. We interpret this as the direct impact of the effective irradiation of the cavity wall, as a result of the planet formation process. Moreover, we have found evidence of an O-poor gas reservoir in the outer disk, which is supported by the observations of bright C-rich molecules, the non-detection of SO, and a lower limit on the $\mathrm{CS/SO}$ ratio of $\sim1$. Eventually, we provide the first detection of the c-C$_3$H$_2$ transitions at 218.73 GHz, and the marginal detection of an azimuthal asymmetry in the higher-energy H$_2$CO (3$_{2,1}$-2$_{2,0}$) line, which could be due to accretion heating near PDS 70b.

Strategic Marketing and Communication Plan

Stakeholder mapping

description: EOSC-Life is a complex project that began with 12 work packages and expanded to 14 as the project progressed. The project also brought together the 13 life science research infrastructures on the ESFRI roadmap and involved a total of 50 partners by the project’s end. The stakeholders were identified early in the project as spanning a broad range of focus areas, and a considerable amount of thought was invested in planning subsequent outreach efforts to optimise communication. Milestone MS32, the Strategic Marketing and Communication Plan, enabled the identification of key stakeholders that would be the target of the communication efforts, as well as the clear definition of the communication means and goals. Milestone MS33, Stakeholder Mapping, then allowed the stakeholders to be preliminarily categorised into 30 categories, and different communication strategies to be defined for these categories, depending on whether they were broadly recognised as stakeholders who were key players, needed to be kept informed, kept satisfied, or merely monitored. Deliverable D10.1, the Strategic Marketing and Stakeholder Mapping Report, provided an updated overview of the information initially provided in MS32 and MS33. This was based on input received from the work packages during the first half of the project and considered changes in communication strategies and tools that became necessary due to the COVID-19 pandemic. The input received resulted in an updated Stakeholder Map, featuring 24 stakeholder categories in 4 broad groups, which was used for the remainder of the project. This Deliverable D10.2 presents an updated Stakeholder Map based on work package leader feedback and reviews the effectiveness and impact of outreach and stakeholder engagement due to work package communication efforts throughout the project. We highlight communication strategies and methods ultimately identified as the most effective with the stakeholder categories, emphasising the impact of in-person versus online methods. Finally, we compare the communication targets established one year after the onset of the project (March 1, 2020) with the status achieved near the end of the project (July 1, 2023) to demonstrate our achievements.

Year: 2016
Subjects: subject: Quantum Physics (quant-ph)

description: We present a simple derivation of the interference pattern in matter-wave interferometry as predicted by a class of master equations, by using the density matrix formalism. We apply the obtained formulae to the most relevant collapse models, namely the Ghirardi-Rimini-Weber (GRW) model, the continuous spontaneous localization (CSL) model together with its dissipative (dCSL) and non-markovian generalizations (cCSL), the quantum mechanics with universal position localization (QMUPL) and the Diósi-Penrose (DP) model. We discuss the separability of the collapse models dynamics along the 3 spatial directions, the validity of the paraxial approximation and the amplification mechanism. We obtain analytical expressions both in the far field and near field limits. These results agree with those already derived in the Wigner function formalism. We compare the theoretical predictions with the experimental data from two relevant matter-wave experiments: the 2012 far-field experiment and the 2013 Kapitza Dirac Talbot Lau (KDTL) near-field experiment of Arndt's group. We show the region of the parameter space for each collapse model, which is excluded by these experiments. We show that matter-wave experiments provide model insensitive bounds, valid for a wide family of dissipative and non-markovian generalizations.

description: The purpose of this study was to explore the information needs of humanities graduate students with the intention of applying what is learned towards improvement in library instructional services and resources. The questions framing this study were: (1) What are the information needs of humanities graduate students? (2) How do current library instructional services and resources meet these needs? Eleven graduate students from the departments of Classics, Communication Studies, English and Comparative Literature, History, Philosophy, and Religious Studies at UNC-Chapel Hill participated in qualitative, in-depth interviews. Using the critical incident technique, the researcher asked participants to describe an information need related to their coursework. The information needs of humanities graduate students primarily include locating secondary source materials for research papers. Findings suggest that humanities graduate students are not heavy users of instructional resources and services. Participants suggested methods to increase awareness of instructional services and resources, including how to improve bibliographic instruction sessions catered to humanities graduate students.

description: A primordial inflationary phase allows one to erase any possible anisotropic expansion thanks to the cosmic no-hair theorem. If there is no global anisotropic stress, then the anisotropic expansion rate tends to decrease. What are the observational consequences of a possible early anisotropic phase? We first review the dynamics of anisotropic universes and report analytic approximations. We then discuss the structure of dynamical equations for perturbations and the statistical properties of observables, as well as the implication of a primordial anisotropy on the quantization of these perturbations during inflation. Finally we briefly review models based on primordial vector field which evade the cosmic no-hair theorem.

description: This study describes the use of exit interviews in Maryland public and academic libraries. Fifty-five libraries were surveyed to determine if exit interviews were conducted with voluntarily departing employees, and what purpose those exit interviews served. Responses were received from 76.4% of the libraries surveyed. Exit interviews were more likely to be conducted in public libraries than in academic libraries. They were most commonly used in both types of libraries to gain information that departing employees could offer, based on their experience working in the library. The second most common use for exit interviews in both types of libraries was to address administrative issues. Small public libraries that did not conduct exit interviews indicated that small staff and low turnover precluded the use of exit interviews. Academic libraries most often responded that exit interviews were conducted by institutional human resources departments, rather than within the library.

description: Raman scattering is the inelastic process where photons bounce off molecules, losing energy and becoming red-shifted. This weak effect is unique to each molecular species, making it an essential tool in e.g. spectroscopy and label-free microscopy. The invention of the laser enabled a regime of stimulated Raman scattering (SRS), where the efficiency is greatly increased by inducing coherent molecular oscillations. However, this phenomenon required high intensities due to the limited interaction volumes, and this limitation was overcome by the emergence of anti-resonant fibres (ARFs) guiding light in a small hollow channel over long distances. Based on their unique properties, this Perspective reviews the transformative impact of ARFs on modern SRS-based applications ranging from development of light sources and convertors for spectroscopy and materials science, to quantum technologies for the future quantum networks, providing insights into future trends and the expanding horizons of the field.

description: In response to the global need for efficient early diagnosis of Autism Spectrum Disorder (ASD), this paper bridges the gap between traditional, time-consuming diagnostic methods and potential automated solutions. We propose a multi-atlas deep ensemble network, MADE-for-ASD, that integrates multiple atlases of the brain's functional magnetic resonance imaging (fMRI) data through a weighted deep ensemble network. Our approach integrates demographic information into the prediction workflow, which enhances ASD diagnosis performance and offers a more holistic perspective on patient profiling. We experiment with the well-known publicly available ABIDE (Autism Brain Imaging Data Exchange) I dataset, consisting of resting state fMRI data from 17 different laboratories around the globe. Our proposed system achieves 75.20% accuracy on the entire dataset and 96.40% on a specific subset $-$ both surpassing reported ASD diagnosis accuracy in ABIDE I fMRI studies. Specifically, our model improves by 4.4 percentage points over prior works on the same amount of data. The model exhibits a sensitivity of 82.90% and a specificity of 69.70% on the entire dataset, and 91.00% and 99.50%, respectively, on the specific subset. We leverage the F-score to pinpoint the top 10 ROI in ASD diagnosis, such as precuneus and anterior cingulate/ventromedial. The proposed system can potentially pave the way for more cost-effective, efficient and scalable strategies in ASD diagnosis. Codes and evaluations are publicly available at https://github.com/hasan-rakibul/MADE-for-ASD.

description: Although nonsymmorphic symmetry protects $\mathbb{Z}_4$ topology for Hermitian systems, non-Hermitian topological phenomena induced by such a unique topological structure remain elusive. In this paper, we elucidate that systems with glide symmetry exhibit non-Hermitian skin effects (NHSE) characterized by $\mathbb{Z}_4$ topology. Specifically, numerically analyzing a two-dimensional toy model, we demonstrate that the $\mathbb{Z}_4$ topology induces the NHSE when the topological invariant takes $ν=1,2$. Furthermore, our numerical analysis demonstrates that the NHSE is destroyed by perturbations preserving the relevant symmetry when the $\mathbb{Z}_4$-invariant takes $ν=4$.

description: This study examines the use of e-government services by North Carolina county governments. The study was conducted to investigate at what stage of e-government North Carolina counties have reached. Three variables were examined to determine which, if any, could explain the e-government stage where the counties are The three variables were region, economic development tier level, and broadband access.
Methods employed over the course of the study included sending a survey to county IT directors and managers, and examining county websites in the case of non-response. Zero counties were found to be at the Presence stage, while 13% were found to be at the Interactive stage, and 87% are at the Transactional stage-which was divided into Early and Advanced Transactional stages for closer inspection. Though the variables individually can impact Internet or e-government uses, none of them completely explain the e-government stage of North Carolina counties.

In examining this question the author analyzed the seven winning books selected by YALSA's Printz Award Selection Committee and compared them to the six books selected by the Eva Perry Mock Printz Book Club at the Eva Perry Regional Public Library in Apex, NC. The findings suggest that YALSA's Printz Selection committee selects novels with a semi-political agenda in mind and with the intention of encouraging advances in the field of young adult publishing. The Eva Perry Mock Printz Book Club selects novels that meet particular adolescent developmental needs, that share a common theme, (the protagonist's desire to be mothered) and a common grade level readability score, (the 6th grade).

description: We study the problem of identifying the source of a diffusion spreading over a regular tree. When the degree of each node is at least three, we show that it is possible to construct confidence sets for the diffusion source with size independent of the number of infected nodes. Our estimators are motivated by analogous results in the literature concerning identification of the root node in preferential attachment and uniform attachment trees. At the core of our proofs is a probabilistic analysis of Pólya urns corresponding to the number of uninfected neighbors in specific subtrees of the infection tree. We also provide an example illustrating the shortcomings of source estimation techniques in settings where the underlying graph is asymmetric.

description: The Metadata Standards Directory Working Group that is part of the Research Data Alliance (RDA) is charged with creating a directory of metadata standards.  The Digital Curation Centre's (DCC) Disciplinary Metadata Catalogue was selected as a starting point for this effort. A form was created to gather information on eleven aspects of metadata standards, and distributed via email across several interest groups in order to collect information on metadata standards.
The thirty-two responses were evaluated; new and supplemental information was extracted and formatted for uploading onto the DCC's Web page. This resulted in the addition of eleven new standards, ten new extensions, twelve new tools, and twenty-three new use cases. This paper reports the results of this information gathering activity, including a display of the range of metadata standards, extensions, tools, and disciplines received in the responses. Suggestions for the next steps toward an open and collaborative directory are also included.
Information Literacy Without Walls: Toward a Collaborative Model for Transitional Library Instruction

description: This paper explores the inconsistency in preparation of first-year university students for college-level research and coursework. A survey of first-year students in North Carolina was executed to measure the availability and impact of library instruction, seeking ways that academic librarians might intervene to address gaps in student information literacy experienced by college-bound students. Librarians across the state were interviewed to explore known information needs among these students and ways that university librarians could contribute to solutions. Survey data and responses from interview subjects suggest a need to improve support for information literacy skills as students prepare for post-secondary learning. Further research is needed to develop a collaborative model involving academic librarians, faculty, and school media coordinators to define and develop the skills needed by students in their college coursework and lifelong learning.

description: The effects of radiation reaction force on laser driven auto-resonant particle acceleration scheme are studied using Landau-Lifshitz equation of motion. These studies are carried out for both linear as well as circularly polarized laser fields in the presence of static axial magnetic field. From the parametric study, a radiation reaction dominated region has been identified in which the particle dynamics is greatly effected by this force. In the radiation reaction dominated region the two significant effects on particle dynamics are seen viz., (1) saturation in energy gain by the initially resonant particle, (2) net energy gain by a initially non-resonant particle which is caused due to resonance broadening. It has been further shown that with the optimum choice of parameters this scheme can be efficiently used to produce electrons with energies in the range of hundreds of TeV. The quantum corrections to the Landu-Lifshitz equation of motion have also been taken into account. The difference in the energy gain estimates of the particle by the quantum corrected and classical Landu-Lifshitz equation are found to be insignificant for the present day as well as upcoming laser facilities.

description: A three-dimensional elemental carbon Kagome lattice (CKL), made of only fourfold coordinated carbon atoms, is proposed based on first-principles calculations. Despite the existence of 60° bond angles in the triangle rings, widely perceived to be energetically unfavorable, the CKL is found to display exceptional stability comparable to that of C60. The system allows us to study the effects of triangular frustration on the electronic properties of realistic solids, and it demonstrates a metal-insulator transition from that of graphene to a direct gap semiconductor in the visible blue region. By minimizing s-p orbital hybridization, which is an intrinsic property of carbon, not only the band edge states become nearly purely frustrated p states, but also the band structure is qualitatively different from any known bulk elemental semiconductors. For example, the optical properties are similar to those of direct-gap semiconductors GaN and ZnO, whereas the effective masses are comparable or smaller than those of Si.

description: Ice-coated dust grains provide the main reservoir of volatiles that play an important role in planet formation processes and may become incorporated into planetary atmospheres. However, due to observational challenges, the ice abundance distribution in protoplanetary disks is not well constrained. We present JWST/MIRI observations of the edge-on disk HH 48 NE carried out as part of the IRS program Ice Age. We detect CO$_2$, NH$_3$, H$_2$O and tentatively CH$_4$ and NH$_4^+$. Radiative transfer models suggest that ice absorption features are produced predominantly in the 50-100 au region of the disk. The CO$_2$ feature at 15 micron probes a region closer to the midplane (z/r = 0.1-0.15) than the corresponding feature at 4.3 micron (z/r = 0.2-0.6), but all observations trace regions significantly above the midplane reservoirs where we expect the bulk of the ice mass to be located. Ices must reach a high scale height (z/r ~ 0.6; corresponding to modeled dust extinction Av ~ 0.1), in order to be consistent with the observed vertical distribution of the peak ice optical depths. The weakness of the CO$_2$ feature at 15 micron relative to the 4.3 micron feature and the red emission wing of the 4.3 micron CO$_2$ feature are both consistent with ices being located at high elevation in the disk. The retrieved NH$_3$ abundance and the upper limit on the CH$_3$OH abundance relative to H$_2$O are significantly lower than those in the interstellar medium (ISM), but consistent with cometary observations. Full wavelength coverage is required to properly study the abundance distribution of ices in disks. To explain the presence of ices at high disk altitudes, we propose two possible scenarios: a disk wind that entrains sufficient amounts of dust, thus blocking part of the stellar UV radiation, or vertical mixing that cycles enough ices into the upper disk layers to balance ice photodesorption.

description: During early development, extrinsic cues prompt a collection of pluripotent cells to begin the extensive process of cellular differentiation that gives rise to all tissues in the mammalian embryo, a process known as gastrulation. Advances in stem cell biology have resulted in the generation of stem cell-based in vitro models of mammalian gastrulation called gastruloids. Gastruloids and subsequent gastruloid-based models are tractable, scalable and more accessible than mammalian embryos. As such, they have opened an unprecedented avenue for modelling in vitro self-organisation, patterning and fate specification. This review focuses on discussing the recent advances of this rapidly moving research area, clarifying what structures they model and the underlying signal hierarchy. We highlight the exciting potential of these models and where the field might be heading.

Newspapers

description: Borrowing from archival theory, the paper examines the application of More Product, Less Process (MPLP) on newspaper digitization projects. The paper includes an overview of the utilization of historical newspapers as research material and examines the complexities surrounding their preservation and discoverability. Analysis focuses on the strong and long-standing arguments for increased access to historic newspapers, using an exploratory, multi-method approach to examine the impact - potential and realized - of digitization technologies and initiatives on access to these sources. Findings reveal the diversity of approaches to description and granularity in the United States, while also praising the standardization efforts of the National Digital Newspaper Program (NDNP) as well as NDNP's leadership in facilitating access to historic newspapers. Findings demonstrate a need for increased collaboration in order to promote discoverability of digital newspaper collections created without NDNP funding, and suggest a need to de-stigmatize non-compliance with NDNP standards in independently funded projects.

description: Fully entangled fraction is a definition for bipartite states, which is tightly related to bipartite maximally entangled states, and has clear experimental and theoretical significance. In this work, we generalize it to multipartite case, we call the generalized version multipartite fully entangled fraction (MFEF). MFEF measures the closeness of a state to GHZ states. The analytical expressions of MFEF are very difficult to obtain except for very special states, however, we show that, the MFEF of any state is determined by a system of finite-order polynomial equations. Therefore, the MFEF can be efficiently numerically computed.

description: Documenting the American South (DAS) is a digital library project of the Academic Affairs Library at the University of North Carolina at Chapel Hill. The project creates electronic texts marked up in the Text Encoding Initiative Document Type Definition of Standard Generalized Markup Language (TEI SGML). Unfortunately, TEI SGML documents are not viewable by most Web users. As a result, DAS must maintain a large number of HTML files to provide access to the materials. This paper outlines DAS's current system for the creation and maintenance of HTML pages, and describes a system that implements Web database technology to automate the process. The system uses PHP to interface with a MySQL database. The scripts insert information into the database and automatically generate many of the HTML pages that are currently written by hand. The new system will save time and reduce the occurrence of errors in the project's HTML pages.
