Sesleria skipetarum

description: 22. Sesleria skipetarum Ujhelyi (1959b: 61)
 Type:— ALBANIA. [Shkodra district]: Felsige Hügel am Bardanjolt bei Skutari [Shkodra], 30 April 1914, Dörfler 13 (holotype BP-0734297–1040 A!) (sub. Sesleria tenuifolia Schrad.).
 Protologue information:—“Habitat in Albania boreali, in solo serpentinico, in regione collina.”
 Nomenclature:—The name was originally published as Sesleria škipetarum, but corrected according to Art. 60.6 (McNeill et al. 2012).
 Taxonomy:—This name is considered synonym of S. insularis (Valdés & Scholz 2009; Clayton et al. 2016). According to the results of the most recent molecular phylogeny of the genus (Kuzmanović et al., in press.), these two species should not be considered synonyms, as S. skipetarum belongs to Sesleri a sect. Argenteae, while S. insularis belongs to S. sect. Sesleria.

description: We propose a scheme for quantum estimation by means of parametric amplification in circuit Quantum Electrodynamics. The modulation of a SQUID interrupting a superconducting waveguide transforms an initial thermal two-mode squeezed state in such a way that the new state is sensitive to the features of the parametric amplifier. We find the optimal initial parameters which maximize the Quantum Fisher Information. In order to achieve a large number of independent measurements we propose to use an array of non-interacting resonators. We show that the combination of both large QFI and large number of measurements enables -in principle- the use of this setup for Quantum Metrology applications.

description: We discuss a possibility that the so-called reactor antineutrino anomaly can be, at least in part, explained by applying a quantum field-theoretical approach to neutrino oscillations, which in particular predicts a small deviation from the classical inverse-square law at short but macroscopic distances between the neutrino source and detector. An extensive statistical analysis of the reactor data is performed to examine this speculation.

description: We develop a procedure for the complete computational enumeration of lattice $3$-polytopes of width larger than one, up to any given number of lattice points. We also implement an algorithm for doing this and enumerate those with at most eleven lattice points (there are 216,453 of them). In order to achieve this we prove that if $P$ is a lattice 3-polytope of width larger than one and with at least seven lattice points then it fits in one of three categories that we call boxed, spiked and merged. Boxed polytopes have at most 11 lattice points; in particular they are finitely many, and we enumerate them completely with computer help. Spiked polytopes are infinitely many but admit a quite precise description (and enumeration). Merged polytopes are computed as a union (merging) of two polytopes of width larger than one and strictly smaller number of lattice points.

Lyman-Alpha Emitting Galaxies as a Probe of Reionization: Large-Scale Bubble Morphology and Small-Scale Absorbers

description: The visibility of LyA emitting galaxies during the Epoch of Reionization is controlled by both diffuse HI patches in large-scale bubble morphology and small-scale absorbers. To investigate the impact on LyA photons, we apply a novel combination of analytic and numerical calculations to three scenarios: (i) the `bubble' model, where only diffuse HI outside ionized bubbles is present; (ii) the `web' model, where HI exists only in overdense self-shielded gas; and (iii) the more realistic 'web-bubble' model, which contains both. Our analysis confirms that there is a degeneracy between the ionization structure of the intergalactic medium (IGM) and the HI fraction inferred from LyA surveys, as the three models suppress LyA flux equally with very different HI fractions. We argue that a joint analysis of the LyA luminosity function and the rest-frame equivalent width distribution/LyA fraction can break this degeneracy and provide constraints on the reionization history and its topology. We further show that constraints can improve if we consider the full shape of the M_UV-dependent redshift evolution of the LyA fraction of Lyman break galaxies. Contrary to conventional wisdom, we find that (i) a drop of LyA fraction larger for UV-faint than for UV-bright galaxies can be reproduced with web and web-bubble models and therefore does not provide exclusive evidence of patchy reionization, and (ii) the IGM-transmission PDF is unimodal for bubble models and bimodal in web models. We further highlight the importance of galaxy-absorber cross-correlation. Comparing our models to observations, the neutral fraction at z~7 is likely to be of order of tens of per cent when interpreted with bubble or web-bubble models. Alternatively, we obtain a conservative lower limit ~1% in the web models, if we allow for a drop in the photoionization rate by a factor of ~100 from the post-reionized universe. [abridged]

description: This study describes a web-based survey of Odum Institute research customers at the  University of North Carolina at Chapel Hill. The survey was conducted to determine the  applicability of digital repository software called the Dataverse Network in social science  research workflows.  The software allows researchers greater personal control over ingest processes, bridging  the gap between researchers and archives and possibly increasing submission rates of  valuable data to archives. This archival technology provides tools that manage automated  ingest, data cataloging, advanced search, as well as rights management issues. Archival  tools also provide proper citation, creation of persistent identifiers, automatic creation of  preservation formats, format migration, and statistical analysis of data. Customized  branding and citation management can provide investigators collecting these data with a  tool that will ensure that they get the credit they deserve. By working together with data  producers, archivists can have more control of the digital curation process.

description: This study explores the BitTorrent file sharing technology as a means for the construction of a digital library by a community of decentralized internet users. The private BitTorrent tracker What.CD, which currently has over 100,000 users, is the primary focus of the paper. In addition to an overview of the BitTorrent protocol, a detailed analysis of the facets and features of What.CD serves to demonstrate how the collaboration of users contributing their own content via a file sharing website can build an unparalleled library of digital media. It examines the role of authority and privilege at a private BitTorrent tracker, as well as the methods employed by What.CD to maintain a large and well-structured catalog of content produced by a community of anonymous users around the globe.
Quasi-bound states of massive scalar fields in the Kerr black-hole spacetime: Beyond the hydrogenic approximation

description: Rotating black holes can support quasi-stationary (unstable) bound-state resonances of massive scalar fields in their exterior regions. These spatially regular scalar configurations are characterized by instability timescales which are much longer than the timescale $M$ set by the geometric size (mass) of the central black hole. It is well-known that, in the small-mass limit $α\equiv Mμ\ll1$ (here $μ$ is the mass of the scalar field), these quasi-stationary scalar resonances are characterized by the familiar hydrogenic oscillation spectrum: $ω_{\text{R}}/μ=1-α^2/2{\bar n}^2_0$, where the integer $\bar n_0(l,n;α\to0)=l+n+1$ is the principal quantum number of the bound-state resonance (here the integers $l=1,2,3,...$ and $n=0,1,2,...$ are the spheroidal harmonic index and the resonance parameter of the field mode, respectively). As it depends only on the principal resonance parameter $\bar n_0$, this small-mass ($α\ll1$) hydrogenic spectrum is obviously degenerate. In this paper we go beyond the small-mass approximation and analyze the quasi-stationary bound-state resonances of massive scalar fields in rapidly-spinning Kerr black-hole spacetimes in the regime $α=O(1)$. In particular, we derive the non-hydrogenic (and, in general, non-degenerate) resonance oscillation spectrum ${ω_{\text{R}}/μ}=\sqrt{1-(α/{\bar n})^2}$, where $\bar n(l,n;α)=\sqrt{(l+1/2)^2-2mα+2α^2}+1/2+n$ is the generalized principal quantum number of the quasi-stationary resonances. This analytically derived formula for the characteristic oscillation frequencies of the composed black-hole-massive-scalar-field system is shown to agree with direct numerical computations of the quasi-stationary bound-state resonances.

description: Research on domestic violence primarily centres on female victims of male-perpetrated violence; less research, however, has been conducted on male victims. This study investigated how male victims of domestic violence are represented in 35 online news articles using critical discourse analysis. The articles were obtained from Factiva from six major newspapers in Australia between 2018-2021. The most pertinent findings of this study included most articles were considered short in length demonstrating an absence of newsworthiness; men were rarely referred to by name making them an invisible entity; an over-reporting of fatal domestic violence compared to the larger proportion of abuse being non-physical; non-physical abuse was rarely reported on; men were rarely referred to as ‘victim’; and elements of victim-blaming were prevalent. These findings suggest that Australian media does not report male victimisation in ways that increase awareness and credibility. Further, this study demonstrates that there is long way to go in recognising and legitimising the experiences of victimisation that men experience as domestic violence victims.

description: Graphic novels are often accused of exploiting women and being excessively violent. To date there has been little research on graphic novels, but this relatively new medium is rapidly increasing in popularity. This study examines graphic novels at a crucial point: they are circulating widely but they have not yet been subjected to revised collection development policies in most libraries.   To determine whether graphic novels collection development policies need to be adjusted, this study used a feminist framework to analyze the content of ten percent of the graphic novels collection at the School of Information and Library Science (SILS) Library at the University of North Carolina (UNC). The content analysis results indicate that more men than women are protagonists, men are likelier to commit physical violence, and women are more likely to be suggestively clad or naked. Recommendations for collecting pro-feminist books to supplement existing graphic novels collections are included.

description: Linear codes have been an interesting topic in both theory and practice for many years. In this paper, for an odd prime $p$, we present the explicit complete weight enumerator of a family of $p$-ary linear codes constructed with defining set. The weight enumerator is an mmediate result of the complete weight enumerator, which shows that the codes proposed in this paper are three-weight linear codes. Additionally, all nonzero codewords are minimal and thus they are suitable for secret sharing.

description: Understanding the charged current quasielestic (CCQE) neutrino-nucleus interaction is important for precision studies of neutrino oscillations. The theoretical description of the interaction depends on the combination of a nuclear model with the knowledge of form factors. While the former has received considerable attention, the latter, in particular the axial form factor, is implemented using the historical dipole model. Instead, we use a model-independent approach, presented in a previous study, to analyze the muon antineutrino CCQE mineral oil data published by the MiniBooNE collaboration. We combine the cross section for scattering of antineutrinos off protons in carbon and hydrogen, using the same axial form factor for both. The extracted value of the axial mass parameter $m_A = 0.84^{+0.12}_{-0.04} \pm {0.11} \, {\rm GeV}$ is in very good agreement with the model-independent value extracted from MiniBooNE's neutrino data. Going beyond a one-parameter description of the axial form factor, we extract values of the axial form factor in the range of $Q^2=0.1...1.0$ GeV$^2$, finding a very good agreement with the analogous extraction from the neutrino data. We discuss the implications of these results.

description: It is known that a solution of remnant were suggested for black hole ground state after surface gravity is corrected by loop quantum effect. On the other hand, a Schwarzschild black hole in asymptotic Anti-de Sitter space would tunnel into the thermal soliton solution known as the Hawking-Page phase transition. In this letter, we investigate the low temperature phase of three-dimensional BTZ black hole and four-dimensional AdS Schwarzschild black hole. We find that the thermal soliton is energetically favored than the remnant solution at low temperature in three dimensions, while Planck-size remnant is still possible in four dimensions. Though the BTZ remnant seems energetically disfavored, we argue that it is still possible to be found in the overcooled phase if strings were present and its implication is discussed.

description: Within the last few years, academic libraries have begun to introduce electronic reserve services. Law libraries are naturally suited to this type of service because law schools have included digital materials in the curriculum for many years. The convenient access provided by electronic reserves makes their use inevitable. Whether these materials are in a formal electronic reserve collection or are mounted on faculty homepages, the same legal concerns exist. Placing them under the auspices of the library aids ease of control and helps minimize any legal exposure that the law school may incur. This paper discusses the advantages and disadvantages of electronic reserves, the Copyright Law, relevant past litigation, current reserve room policies, and suggested new standards. In conclusion, the paper looks at where the law in this area is likely to move and what response will best serve law libraries.

description: Adaptive data collection and analysis, where data are being fed back to update the measurement settings, can greatly increase speed, precision, and reliability of the characterization of quantum systems. However, decoherence tends to make adaptive characterization difficult. As an example, we consider two coupled discrete quantum systems. When one of the systems can be controlled and measured, the standard method to characterize another, with an unknown frequency $ω_{\rm r}$, is swap spectroscopy. Here, adapting measurements can provide estimates whose error decreases exponentially in the number of measurement shots rather than as a power law in conventional swap spectroscopy. However, when the decoherence time is so short that an excitation oscillating between the two systems can only undergo less than a few tens of vacuum Rabi oscillations, this approach can be marred by a severe limit on accuracy unless carefully designed. We adopt machine learning techniques to search for efficient policies for the characterization of decohering quantum systems. We find, for instance, that when the system undergoes more than 2 Rabi oscillations during its relaxation time $T_1$, $O(10^3)$ measurement shots are sufficient to reduce the squared error of the Bayesian initial prior of the unknown frequency $ω_{\rm r}$ by a factor $O(10^4)$ or larger. We also develop policies optimized for extreme initial parameter uncertainty and for the presence of imperfections in the readout.

description: Today's information consumer wants to interact with and contribute to information resources that they encounter. Digital library managers must balance the benefit provided by user contributions, with content quality. In this paper, we characterize existing technologies into six categories based on the role of the user at the time of contribution. We then introduce an evaluation framework comprised of five criteria: validity, accessibility, accountability, utility, and resource requirements. We demonstrate the feasibility of this framework by providing a detailed analysis for three of the six categories, and for a case study of Documenting the American South (DocSouth), which is part of the Carolina Digital Library and Archives at the University of North Carolina at Chapel Hill. We conclude with recommendations for methods that best satisfy the needs of DocSouth.

description: The aim of this report is to provide information on inspiring practice cases of bottom-up initiatives across the 34 countries that have been mapped within the ACCTING EU project. The report examines the types and characteristics of the initiatives mapped. In Chapter 1, the main Concepts & Methods of ACCTING EU project are introduced. In Chapter 2 the research activity of ‘mapping Bottom-Up Initiative (BUIs)’ is described. Further in Chapter 3, the mapped BUIs are presented according to the eight research lines. In this central chapter for each research line an analysis of the bottom-up initiatives is presented highlighting common themes of implementation, justice profiles and specific barriers and drivers. Chapter 4 and Chapter 5, Discussion and Final Remarks, discuss the results of the analysis of all the mapped BUIs across the different research lines. What emerges is that most BUIs focus on the themes of food and land; energy is also a central issue. Further, the BUIs surveyed appear to focus mostly on the vulnerabilities based on income, rural/urban gap, age, and ethnicity. They are led by various actors, principally citizens' and community organisations, voluntary organisations, NGOs, and micro and small enterprises, suggesting a vitality of the civil society in promoting the green transition. However, local authorities and the public sector influence barriers and drivers for many BUIs. Drivers that propel many of the BUIs include internally held resources such as finances, awareness,information, knowledge and education (AIKE) and pro-environmental and prosocial attitudes. Additionally, the analysis highlights that, contextual drivers and barriers, such as prosocial culture in the community, play a role in supporting collective actions, particularly at the neighbourhood level, where social bonds are active and strong. The research presented, albeit non-conclusive and part of a larger research process within the ACCTING project, suggests that societies still face a wide problem of distributive justice and recognition justice that civil society actors consider a priority in promoting the green transition. The analysis also shows a window of opportunity for learning, knowledge transfer and future research: while there is a relatively low number of BUIs explicitly addressing gender+ inequality issues, they do exist. The challenge for future research is to learn from those BUIs that do address gender+ inequalities and to transfer these insights to those who do not, as well as to translate this knowledge to operational recommendations.
Volterra filters for quantum estimation and detection

description: The implementation of optimal statistical inference protocols for high-dimensional quantum systems is often computationally expensive. To avoid the difficulties associated with optimal techniques, here I propose an alternative approach to quantum estimation and detection based on Volterra filters. Volterra filters have a clear hierarchy of computational complexities and performances, depend only on finite-order correlation functions, and are applicable to systems with no simple Markovian model. These features make Volterra filters appealing alternatives to optimal nonlinear protocols for the inference and control of complex quantum systems.

Clark Atlanta University--School of Library and Information Studies

description: This project closely examines the circumstances and events surrounding the closing of the Clark Atlanta University School of Library and Information Studies, an event which unfolded over the years of 2003-2005. The author interviewed Clark Atlanta University students, faculty, staff, alumni, administration and representatives from other professional organizations in order to gain some insight into the event and the opinions and perceptions of those embroiled in it. This information, combined with published accounts of the closing, help to paint a clearer picture of what happened. Larger issues including reasons why library schools close, and the value of Historically Black Institutions are also discussed in the context of the closing. Difficulties in communication among stakeholder groups are among the findings of this research.

description: A general theory of reproducing kernels and reproducing kernel Hilbert spaces on a right quaternionic Hilbert space is presented. Positive operator valued measures and their connection to a class of generalized quaternionic coherent states are examined. A Naimark type extension theorem associated with the positive operator valued measures is proved in a right quaternionic Hilbert space. As illustrative examples, real, complex and quaternionic reproducing kernels and reproducing kernel Hilbert spaces arising from Hermite and Laguerre polynomials are presented. In particular, in the Laguerre case, the Naimark type extension theorem on the associated quaternionic Hilbert space is indicated.

description: Myoelectric control is an area of electromyography of increasing interest nowadays, particularly in applications such as Hand Gesture Recognition (HGR) for bionic prostheses. Today's focus is on pattern recognition using Machine Learning and, more recently, Deep Learning methods. Despite achieving good results on sparse sEMG signals, the latter models typically require large datasets and training times. Furthermore, due to the nature of stochastic sEMG signals, traditional models fail to generalize samples for atypical or noisy values. In this paper, we propose the design of a Vision Transformer (ViT) based architecture with a Fuzzy Neural Block (FNB) called EMGTFNet to perform Hand Gesture Recognition from surface electromyography (sEMG) signals. The proposed EMGTFNet architecture can accurately classify a variety of hand gestures without any need for data augmentation techniques, transfer learning or a significant increase in the number of parameters in the network. The accuracy of the proposed model is tested using the publicly available NinaPro database consisting of 49 different hand gestures. Experiments yield an average test accuracy of 83.57\% \& 3.5\% using a 200 ms window size and only 56,793 trainable parameters. Our results outperform the ViT without FNB, thus demonstrating that including FNB improves its performance. Our proposal framework EMGTFNet reported the significant potential for its practical application for prosthetic control.

Public records--Management

description: Electronic records are creating new challenges for state records units. These units are tasked with assisting state agencies with their public records.  Electronic public records require new approaches to both day-to-day management and long-term preservation. As records units try to address these issues, they often face bureaucratic barriers.
This research paper adapts public administration literature focused on three organizational frameworks including structural, political, and human resources to offer recommendations on how records units can create electronic records management solutions that records creators will adopt. Twelve records management practitioners from 11 different states were interviewed for this study. Their responses were used to develop recommendations on how to implement electronic record-keeping initiatives keeping in mind some of the challenges created by the institutional structures and cultures of state government.

description: The analysis of galaxy properties and the relations among them and the environment, can be used to investigate the physical processes driving galaxy evolution. We study the cluster A209 by using the CLASH-VLT spectroscopic data combined with Subaru photometry, yielding to 1916 cluster members down to a stellar mass of 10^{8.6} Msun. We determine: i) the stellar mass function of star-forming and passive galaxies; ii) the intra-cluster light and its properties; iii) the orbits of low- and high-mass passive galaxies; and iv) the mass-size relation of ETGs. The stellar mass function of the star-forming galaxies does not depend on the environment, while the slope found for passive galaxies becomes flatter in the densest region. The color distribution of the intra-cluster light is consistent with the color of passive members. The analysis of the dynamical orbits shows that low-mass passive galaxies have tangential orbits, avoiding small pericenters around the BCG. The mass-size relation of low-mass passive ETGs is flatter than that of high mass galaxies, and its slope is consistent with that of field star-forming galaxies. Low-mass galaxies are also more compact within the scale radius of 0.65 Mpc. The ratio between stellar and number density profiles shows a mass segregation in the center. The comparative analysis of the stellar and total density profiles indicates that this effect is due to dynamical friction. Our results are consistent with a scenario in which the "environmental quenching" of low-mass galaxies is due to mechanisms such as harassment out to R200, starvation and ram-pressure stripping at smaller radii, as supported by the analysis of the mass function, of the dynamical orbits and of the mass-size relation of passive early-types in different regions. Our analyses support the idea that the intra-cluster light is formed through the tidal disruption of subgiant galaxies.

description: Many methods have been proposed to detect communities, not only in plain, but also in attributed, directed or even dynamic complex networks. From the modeling point of view, to be of some utility, the community structure must be characterized relatively to the properties of the studied system. However, most of the existing works focus on the detection of communities, and only very few try to tackle this interpretation problem. Moreover, the existing approaches are limited either by the type of data they handle, or by the nature of the results they output. In this work, we see the interpretation of communities as a problem independent from the detection process, consisting in identifying the most characteristic features of communities. We give a formal definition of this problem and propose a method to solve it. To this aim, we first define a sequence-based representation of networks, combining temporal information, community structure, topological measures, and nodal attributes. We then describe how to identify the most emerging sequential patterns of this dataset, and use them to characterize the communities. We study the performance of our method on artificially generated dynamic attributed networks. We also empirically validate our framework on real-world systems: a DBLP network of scientific collaborations, and a LastFM network of social and musical interactions.

description: Monitoring the electrical pulse of fetal heart through a non-invasive fetal electrocardiogram (fECG) can easily detect abnormalities in the developing heart to significantly reduce the infant mortality rate and post-natal complications. Due to the overlapping of maternal and fetal R-peaks, the low amplitude of the fECG, systematic and ambient noises, typical signal extraction methods, such as adaptive filters, independent component analysis, empirical mode decomposition, etc., are unable to produce satisfactory fECG. While some techniques can produce accurate QRS waves, they often ignore other important aspects of the ECG. Our approach, which is based on 1D CycleGAN, can reconstruct the fECG signal from the mECG signal while maintaining the morphology due to extensive preprocessing and appropriate framework. The performance of our solution was evaluated by combining two available datasets from Physionet, "Abdominal and Direct Fetal ECG Database" and "Fetal electrocardiograms, direct and abdominal with reference heartbeat annotations", where it achieved an average PCC and Spectral-Correlation score of 88.4% and 89.4%, respectively. It detects the fQRS of the signal with accuracy, precision, recall and F1 score of 92.6%, 97.6%, 94.8% and 96.4%, respectively. It can also accurately produce the estimation of fetal heart rate and R-R interval with an error of 0.25% and 0.27%, respectively. The main contribution of our work is that, unlike similar studies, it can retain the morphology of the ECG signal with high fidelity. The accuracy of our solution for fetal heart rate and R-R interval length is comparable to existing state-of-the-art techniques. This makes it a highly effective tool for early diagnosis of fetal heart diseases and regular health checkups of the fetus.

Eye tracking

description: Graphic novels, a large and growing part of the popular culture, are found across society from private homes to University Libraries.  They have been found to be of benefit to early and reluctant readers and are also used for other tasks in the private and business sphere.  As graphic novels become more popular, new forms of page layout are appearing.  This exploratory study examined how university undergraduate's eyes traveled across specific 'dominant/inset' page layouts. Participants' eye tracking data were collected using a Tobii Pro X2-30 Eye Tracker. Participants' scanpaths were analyzed using visual analysis techniques to determine how closely they corresponded to the Chronological Sequence Path set by creators.  This study found that readers more familiar with graphic novels read these pages in a smoother fashion and were less likely to revisit text than novices.
