description: As the practice of integrative medicine becomes more common, it is important for library science professionals to understand the research needs of integrative medicine professionals in order to best provide resources and services to this population. This paper surveys integrative medicine professionals affiliated with the four North Carolina academic programs and centers for integrative medicine. The results of this study indicate that this population may need more targeted library services due to the difficulty in finding information in this field.

description: We use leading-order anisotropic hydrodynamics to study an azimuthally-symmetric boost-invariant quark-gluon plasma. We impose a realistic lattice-based equation of state and perform self-consistent anisotropic freeze-out to hadronic degrees of freedom. We then compare our results for the full spatiotemporal evolution of the quark-gluon plasma and its subsequent freeze-out to results obtained using 1+1d Israel-Stewart second-order viscous hydrodynamics. We find that for small shear viscosities, 4 pi eta/s ~ 1, the two methods agree well for nucleus-nucleus collisions, however, for large shear viscosity to entropy density ratios or proton-nucleus collisions we find important corrections to the Israel-Stewart results for the final particle spectra and the total number of charged particles. Finally, we demonstrate that the total number of charged particles produced is a monotonically increasing function of 4 pi eta/s in Israel-Stewart viscous hydrodynamics whereas in anisotropic hydrodynamics it has a maximum at 4 pi eta/s ~ 10. For all 4 pi eta/s > 0, we find that for Pb-Pb collisions Israel-Stewart viscous hydrodynamics predicts more dissipative particle production than anisotropic hydrodynamics.

description: Interferon(IFN)-based hepatitis C virus (HCV) therapy has been replaced by direct-acting antivirals (DAAs). We assessed temporal trends in patient characteristics, transmission risks, treatment initiation, and cure rates in eras of IFN, restricted DAA-access, and unrestricted DAA-access in Viennese HCV/HIV-coinfected patients (HIV/HCV). Consecutive HIV/HCV-coinfected patients starting HCV treatment at the Vienna General Hospital between 2002 and 2020 were retrospectively enrolled. Of all N = 508 HIV/HCV, 78% (398/508) were male and the mean age was 41.8 ± 9.5 years. ‘People-who-inject-drugs’ (PWID) accounted for 61% (311/508), while 31% (156/508) were ‘men who have sex with men’ (MSM). In the IFN-era, restricted DAA-era and unrestricted DAA-era, N = 152, N = 129, and N = 227 HCV treatments were started and 49% (74/152), 95% (122/129), and 88% (200/227) achieved sustained virologic response, respectively. Treatment during the IFN-era was a strong predictor for virologic non-response (aOR 12.69; 6.93–23.24) and loss-to-follow-up (aOR 6.12; 2.99–12.54), while virologic non-response was less common in ‘MSM’ (aOR 0.28; 0.13–0.62). Ninety three percent (50/54) of the observed HCV reinfections occurred in the unrestricted DAA-era. A substantial increase in ‘MSM’ transmission was observed since 2010 with 66% (107/161) in the DAA-era versus 15% (49/330) prior to the DAA-era. HCV cure rates in Viennese HIV patients increased from 49% in the IFN-era to 88–95% in the DAA-era. MSM-related risk behaviour and reinfections became the key challenges towards HCV elimination in HIV-coinfected patients.

description: Among Markovian processes, the hallmark of Lévy flights is superdiffusion, or faster-than-Brownian dynamics. Here we show that Lévy laws, as well as Gaussians, can also be the limit distributions of processes with long range memory that exhibit very slow diffusion, logarithmic in time. These processes are path-dependent and anomalous motion emerges from frequent relocations to already visited sites. We show how the Central Limit Theorem is modified in this context, keeping the usual distinction between analytic and non-analytic characteristic functions. A fluctuation-dissipation relation is also derived. Our results may have important applications in the study of animal and human displacements.

Reading

description: This study examines the portrayal of reading in popular children's fiction. Content analysis was used to determine to what extent characters in a sample of fifteen high-circulating novels for middle grade readers displayed the following positive reading behaviors: reading continuous texts, reading voluntarily, reading for recreation or general interest, sharing reading experiences, and experiencing reading as pleasurable. The study also examined whether male and female readers were equally represented with regard to these positive behaviors. Both male and female readers were represented in the sample texts and exhibited roughly equivalent positive reading behaviors. Models of recreational reading were limited, and texts varied in the positivity or negativity of their depictions of reading, though free voluntary reading was portrayed positively fairly consistently. The study includes an assessment of which texts provide the most positive male and female reading models overall.

Douce, Francis, 1757-1834

description: This paper is a study of the English antiquarian Francis Douce and his collection of books, prints, drawings, coins, and artifacts. The major theme of the collection - the manners, beliefs, and customs of the world - is connected to three of Douce's most remarkable collecting interests: children's books and games; fools and jesters; and the sublime, including his collections of death, demonology, and witchcraft. The collection, divided between the Bodleian Library and the Ashmolean Museum at Oxford, remains an invaluable resource for scholars in a wide variety of fields. It is hoped that this paper will emphasize the vision according to which Douce developed a distinctive collection; that it will shed additional light on British collecting and collectors of Douce's lifetime, 1757-1834; and that it will serve as a lesson in collecting that might be used by librarians and non-librarians alike.

description: The latest IceCube data suggest that the all-flavor cosmic neutrino flux may be as large as 10^-7 GeV/cm^2/s/sr around 30 TeV. We show that, if sources of the TeV-PeV neutrinos are transparent to gamma rays with respect to two-photon annihilation, strong tensions with the isotropic diffuse gamma-ray background measured by Fermi are unavoidable, independently of the production mechanism. We further show that, if the IceCube neutrinos have a photohadronic (pgamma) origin, the sources are expected to be opaque to 1-100 GeV gamma rays. With these general multimessenger arguments, we find that the latest data suggest a population of cosmic-ray accelerators hidden in GeV-TeV gamma rays as a neutrino origin. Searches for x-ray and MeV gamma-ray counterparts are encouraged, and TeV-PeV neutrinos themselves will serve as special probes of dense source environments.

description: This study presents the results of a usability test of Chapel Hill Transit and Triangle Transit Authority websites. Transit websites are one of most common information resources used by travelers and commuters using a transit system. Using usability testing techniques with actual end-users, this study attempts to evaluate and analyze the Chapel Hill Transit and Triangle Transit Authority websites and determine the user attitudes towards the websites. Ten participants performed eight information seeking tasks from the Chapel Hill Transit and Triangle Transit Authority websites and responded to a series of questions about their information seeking experiences and usability of the websites. The study indicated that the Triangle Transit Authority website was user-friendly and the Chapel Hill Transit website had a number of small usability problems. This study identified specific aspects of the Chapel Hill Transit website that can be improved, such as creating better navigation, restructuring the information and content, and adding enhanced search function. Results from this study may be used to improve interface design of transit websites.

Building on a literature review tracing the historical and legal context for contemporary library practice and the practice mandates of copyright law, this exploratory research study surveyed the chief executives of the fifty state library agencies in the U.S. to collect qualitative data on professional practices related to copyright law and risk management, institutional experiences in navigating copyright, and librarian perceptions of their professional roles and responsibilities in the copyright law landscape.
Formally Proved Security of Assembly Code Against Power Analysis: A Case Study on Balanced Logic

Subjects: subject: Cryptography and Security (cs.CR)

description: In his keynote speech at CHES 2004, Kocher advocated that side-channel attacks were an illustration that formal cryptography was not as secure as it was believed because some assumptions (e.g., no auxiliary information is available during the computation) were not modeled. This failure is caused by formal methods' focus on models rather than implementations. In this paper we present formal methods and tools for designing protected code and proving its security against power analysis. These formal methods avoid the discrepancy between the model and the implementation by working on the latter rather than on a high-level model. Indeed, our methods allow us (a) to automatically insert a power balancing countermeasure directly at the assembly level, and to prove the correctness of the induced code transformation; and (b) to prove that the obtained code is balanced with regard to a reasonable leakage model. We also show how to characterize the hardware to use the resources which maximize the relevancy of the model. The tools implementing our methods are then demonstrated in a case study on an 8-bit AVR smartcard for which we generate a provably protected present implementation that reveals to be at least 250 times more resistant to CPA attacks.

The quenching and survival of ultra-diffuse galaxies in the Coma cluster

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We conduct the first self-consistent numerical simulations of a recently discovered population of 47 large, faint (ultra-diffuse) galaxies, speculated to lie in the Coma cluster. With structural properties consistent with very large low surface brightness systems (i.e. $μ$(g,0)$<24$ mag arcsec$^{\rm -2}$, r$_{\rm eff}$ comparable to the Galaxy), the red colour ($\langle$g-r$\rangle$$\sim$0.8) and assumed low metallicity of these objects compels us to consider a scenario in which these are underdeveloped galaxies whose early ($z$$\simeq$2) accretion to an overdense environment quenched further growth. Our simulations demonstrate the efficacy of this scenario, with respect to available observational constraints, using progenitor galaxy models derived from scaling relations, and idealised tidal/hydrodynamical models of the Coma cluster. The apparent ubiquity of these objects in Coma implies they constitute an important galaxy population, we accordingly discuss their properties with respect to a $Λ$CDM cosmology, classical LSBs, and the role of baryonic physics in their early formation.

Computer-mediated communication

description: Mentoring has long been recognized as an effective process to help students and young professionals develop new skills and attitudes. This study analyzed the content of message exchanges between five professional scientists and five minority college students who were paired as part of the E-mentoring program developed at the University of North Carolina at Chapel Hill. Interaction was assessed both quantitatively and qualitatively, with the goal of providing a better understanding of the connection between interactivity patterns and perceived success of a mentor-student relationship. Several factors were identified as contributing to successful interaction, including structure of the exchange; balance of discussion topics; mirroring in content and message length; and limited overt "managing" by mentors.
X-Ray Absorption and Scattering by Interstellar Grains

description: Interstellar abundance determinations from fits to X-ray absorption edges often rely on the incorrect assumption that scattering is insignificant and can be ignored. We show instead that scattering contributes significantly to the attenuation of X-rays for realistic dust grain size distributions and substantially modifies the spectrum near absorption edges of elements present in grains. The dust attenuation modules used in major X-ray spectral fitting programs do not take this into account. We show that the consequences of neglecting scattering on the determination of interstellar elemental abundances are modest; however, scattering (along with uncertainties in the grain size distribution) must be taken into account when near-edge extinction fine structure is used to infer dust mineralogy. We advertise the benefits and accuracy of anomalous diffraction theory for both X-ray halo analysis and near edge absorption studies. An open source Fortran suite, General Geometry Anomalous Diffraction Theory (GGADT), is presented that calculates X-ray absorption, scattering, and differential scattering cross sections for grains of arbitrary geometry and composition.

description: We have observed photon-assisted Cooper-pair tunneling in an atomic-scale Josephson junction formed between a superconducting Nb tip and a superconducting Nb sample in a scanning tunneling microscope (STM) at 30 mK. High-resolution tunneling spectroscopy data show a zero-bias conduction peak and other sharp sub-gap peaks from coupling of the STM junction to resonances in the electromagnetic environment. The sub-gap peaks respond to incident microwave radiation by splitting into multiple peaks with the position and height depending on the frequency and amplitude of the microwaves. The inter-peak spacing shows that the charge carriers are Cooper pairs, rather than quasiparticles, and the power dependence reveals that the current originates from photon-assisted phase-incoherent tunneling of pairs, rather than the more conventional phase-coherent tunneling of pairs that yields Shapiro steps.

description: The X-ray emission from flares on cool (i.e. spectral-type F-M) stars is indicative of very energetic, transient phenomena, associated with energy release via magnetic reconnection. We present a uniform, large-scale survey of X-ray flare emission. The XMM-Newton Serendipitous Source Catalogue and its associated data products provide an excellent basis for a comprehensive and sensitive survey of stellar flares - both from targeted active stars and from those observed serendipitously in the half-degree diameter field-of-view of each observation. The 2XMM Catalogue and the associated time-series (`light-curve') data products have been used as the basis for a survey of X-ray flares from cool stars in the Hipparcos Tycho-2 catalogue. In addition, we have generated and analysed spectrally-resolved (i.e. hardness-ratio), X-ray light-curves. Where available, we have compared XMM OM UV/optical data with the X-ray light-curves. Our sample contains ~130 flares with well-observed profiles; they originate from ~70 stars. The flares range in duration from ~1e3 to ~1e4 s, have peak X-ray fluxes from ~1e-13 to ~1e-11 erg/cm2/s, peak X-ray luminosities from ~1e29 to ~1e32 erg/s, and X-ray energy output from ~1e32 to ~1e35 erg. Most of the ~30 serendipitously-observed stars have little previously reported information. The hardness-ratio plots clearly illustrate the spectral (and hence inferred temperature) variations characteristic of many flares, and provide an easily accessible overview of the data. We present flare frequency distributions from both target and serendipitous observations. The latter provide an unbiased (with respect to stellar activity) study of flare energetics; in addition, they allow us to predict numbers of stellar flares that may be detected in future X-ray wide-field surveys. The serendipitous sample demonstrates the need for care when calculating flaring rates.

description: Research regarding the reading preferences of children often focuses on the  differences between boys and girls, but rarely looks at reading ability as a factor. The  purpose of this study is to address the connection between children's reading  preferences and reading ability. By looking at the school library circulation records  of 2nd, 3rd, and 4th grade students, this study examines relationships between gender,  age, reading ability, and the reading preference of elementary school children.    Quantitative data was collected from circulation records in order to find trends related  to Fiction or Non-Fiction reading choice based on a student's reading ability, age, and  gender. Fiction and Non-Fiction are determined based on call numbers of books  checked-out; specifically, those titles that are picture or chapter books are considered  Fiction, whereas those labeled with Dewey Decimal coding are considered Non-  Fiction. Reading ability--in terms of reading level scores (II, III, or IV)--is  determined by the North Carolina End-of-Grade Test in Reading. The hope is that  the results of this study may contribute to further research and discussion addressing  the relatively poor literacy performance of boys compared to girls both in school and  on standardized achievement tests.

description: Weyl semimetals are gapless quasi-topological materials with a set of isolated nodal points forming their Fermi surface. They manifest their quasi-topological character in a series of topological electromagnetic responses including the anomalous Hall effect. Here we study the effect of disorder on Weyl semimetals while monitoring both their nodal/semi-metallic and topological properties through computations of the localization length and the Hall conductivity. We examine three different lattice tight-binding models which realize the Weyl semimetal in part of their phase diagram and look for universal features that are common to all of the models, and interesting distinguishing features of each model. We present detailed phase diagrams of these models for large system sizes and we find that weak disorder preserves the nodal points up to the diffusive limit, but does affect the Hall conductivity. We show that the trend of the Hall conductivity is consistent with an effective picture in which disorder causes the Weyl nodes move within the Brillouin zone along a specific direction that depends deterministically on the properties of the model and the neighboring phases to the Weyl semimetal phase. We also uncover an unusual (non-quantized) anomalous Hall insulator phase which can only exist in the presence of disorder.

Search for a CP-odd Higgs boson decaying to $Zh$ in $pp$ collisions at $\sqrt{s} = 8$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2015

description: A search for a heavy, CP-odd Higgs boson, $A$, decaying into a $Z$ boson and a 125 GeV Higgs boson, $h$, with the ATLAS detector at the LHC is presented. The search uses proton--proton collision data at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 20.3 fb$^{-1}$. Decays of CP-even $h$ bosons to $\tau\tau$ or $bb$ pairs with the $Z$ boson decaying to electron or muon pairs are considered, as well as $h \rightarrow bb$ decays with the $Z$ boson decaying to neutrinos. No evidence for the production of an $A$ boson in these channels is found and the 95% confidence level upper limits derived for $\sigma (gg\rightarrow A) \times \mbox{BR}(A \rightarrow Zh) \times \mbox{BR}(h \rightarrow f\bar{f})$ are 0.098--0.013 pb for $f=\tau$ and 0.57--0.014 pb for $f=b$ in a range of $m_A =$ 220--1000 GeV. The results are combined and interpreted in the context of two-Higgs doublet models.

description: We use microwave temperature maps from two seasons of data from the Atacama Cosmology Telescope (ACTPol) at 146 GHz, together with the Constant Mass CMASS galaxy sample from the Baryon Oscillation Spectroscopic Survey to measure the kinematic Sunyaev-Zeľdovich (kSZ) effect over the redshift range z = 0.4 - 0.7. We use galaxy positions and the continuity equation to obtain a reconstruction of the line-of-sight velocity field. We stack the cosmic microwave background temperature at the location of each halo, weighted by the corresponding reconstructed velocity. The resulting best fit kSZ model is preferred over the no-kSZ hypothesis at 3.3sigma and 2.9sigma for two independent velocity reconstruction methods, using 25,537 galaxies over 660 square degrees. The effect of foregrounds that are uncorrelated with the galaxy velocities is expected to be well below our signal, and residual thermal Sunyaev-Zeľdovich contamination is controlled by masking the most massive clusters. Finally, we discuss the systematics involved in converting our measurement of the kSZ amplitude into the mean free electron fraction of the halos in our sample.

Search for massive supersymmetric particles decaying to many jets using the ATLAS detector in $pp$ collisions at $\sqrt{s} = 8$ TeV
Creators: name: ATLAS Collaboration
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2015

description: Results of a search for decays of massive particles to fully hadronic final states are presented. This search uses 20.3 fb$^{-1}$ of data collected by the ATLAS detector in $\sqrt{s} = 8$ TeV proton--proton collisions at the LHC. Signatures based on high jet multiplicities without requirements on the missing transverse momentum are used to search for $R$-parity-violating supersymmetric gluino pair production with subsequent decays to quarks. The analysis is performed using a requirement on the number of jets, in combination with separate requirements on the number of $b$-tagged jets, as well as a topological observable formed from the scalar sum of the mass values of large-radius jets in the event. Results are interpreted in the context of all possible branching ratios of direct gluino decays to various quark flavors. No significant deviation is observed from the expected Standard Model backgrounds estimated using jet-counting as well as data-driven templates of the total-jet-mass spectra. Gluino pair decays to ten or more quarks via intermediate neutralinos are excluded for a gluino with mass $m_{\tilde{g}} < 1$ TeV for a neutralino mass $m_{\tilde{\chi}^0_1} = 500$ GeV. Direct gluino decays to six quarks are excluded for $m_{\tilde{g}} < 917$ GeV for light-flavor final states, and results for various flavor hypotheses are presented.

description: Google Scholar and Windows Live Academic Search (WLAS) are examples of "blended" databases, a controversial new class of tools which provide free, speedy access to academic content as well as citation analysis capabilities, linkage to individual library holdings and other services. Though researchers have published dozens of theoretical and empirical studies involving these tools, none have yet described how they are actually being used in a variety of academic settings. The author sent questionnaires to 540 librarians at 108 ARL libraries to learn how they deployed Google Scholar and WLAS in reference transactions and instruction sessions. Participants were also asked speak about the ways that non-traditional databases are affecting research in academic libraries. The author finds that, while these tools provoked mixed reactions among librarians, their popularity and usefulness - especially that of Google Scholar - are forcing librarians to acknowledge the possible arrival of a new paradigm in academic research.

description: The origin of the suppression of the longitudinal spin Seebeck effect by applied magnetic fields is studied. We perform numerical simulations of the stochastic Landau-Lifshitz-Gilbert equation of motion for an atomistic spin model and calculate the magnon accumulation in linear temperature gradients for different strengths of applied magnetic fields and different length scales of the temperature gradient. We observe a decrease of the magnon accumulation with increasing magnetic field and we reveal that the origin of this effect is a field dependent change of the frequency distribution of the propagating magnons. With increasing field the magnonic spin currents are reduced due to a suppression of parts of the frequency spectrum. By comparison with measurements of the magnetic field dependent longitudinal spin Seebeck effect in YIG thin films with various thicknesses, we find that our model describes the experimental data very well, demonstrating the importance of this effect for experimental systems.
