Fiction

description: Research in fiction librarianship has led to improvement in how fiction is classified and organized for use in the public library. While advances have been made in understanding how patrons search for fiction within the public library, little research has been done in the setting of the modern online public access catalog. This study describes a questionnaire survey of public library patrons in the five regional libraries of the Wake County Public Library system in North Carolina. The survey was conducted to evaluate how fiction readers select fiction, to what extent they use the online catalog, and how the online catalog could be improved to better suit fiction readers' needs.

description: There is a countable metrizable group acting continuously on the space of rationals in such a way that the only equivariant compactification of the space is a singleton. This is obtained by a recursive application of a construction due to Megrelishvili, which is a metric fan equipped with a certain group of homeomorphisms. The question of existence of a topological transformation group with the property in the title was asked by Yu.M. Smirnov in the 1980s.

Changing Modalities of Ho Social protest in Colonial Singhbhum
Creators: name: Sen, Asoka
Publisher: name: figshare
Year: 2023
Subjects: Other Indigenous studies not elsewhere classified

description: This paper traverses the entire span of colonial rule in Kolhan of erstwhile Singhbhum to
 unfold the social protest and modalities deployed by the Ho adivasis to vindicate their
 grievances against British rule. The author argues that social ferment was caused mainly due
 to encroachment of alien rules and practices into the customary domain. Sites of protest were
 land and forest, to protect which they resorted both to militant and constitutional modes of
 collective assertion. The essay begins by broaching the masochistic migratory movements
 and militant resistance to feudal and colonial imperialism between 1770 and 1859 as
 modalities of social protest. The narrative then elaborates acts of civil disobedience, Ho
 participation in the Indian national movement and framing petitions to defend their land and
 forest rights. The crux of the argument is that movement from silent to militant and finally to
 legalism was historically conditioned by shifting consciousness of collective self that forced
 them to surrender bow-arrow-battle-axe and tread the path of peaceful protest.

description: Gravitational waves from compact binary mergers are now routinely observed by Earth-bound detectors. These observations enable exciting new science, as they have opened a new window to the Universe. However, extracting gravitational-wave signals from the noisy detector data is a challenging problem. The most sensitive search algorithms for compact binary mergers use matched filtering, an algorithm that compares the data with a set of expected template signals. As detectors are upgraded and more sophisticated signal models become available, the number of required templates will increase, which can make some sources computationally prohibitive to search for. The computational cost is of particular concern when low-latency alerts should be issued to maximize the time for electromagnetic follow-up observations. One potential solution to reduce computational requirements that has started to be explored in the last decade is machine learning. However, different proposed deep learning searches target varying parameter spaces and use metrics that are not always comparable to existing literature. Consequently, a clear picture of the capabilities of machine learning searches has been sorely missing. In this thesis, we closely examine the sensitivity of various deep learning gravitational-wave search algorithms and introduce new methods to detect signals from binary black hole and binary neutron star mergers at previously untested statistical confidence levels. By using the sensitive distance as our core metric, we allow for a direct comparison of our algorithms to state-of-the-art search pipelines. As part of this thesis, we organized a global mock data challenge to create a benchmark for machine learning search algorithms targeting compact binaries. This way, the tools developed in this thesis are made available to the greater community by publishing them as open source software. Our studies show that, depending on the parameter space, deep learning gravitational-wave search algorithms are already competitive with current production search pipelines. We also find that strategies developed for traditional searches can be effectively adapted to their machine learning counterparts. In regions where matched filtering becomes computationally expensive, available deep learning algorithms are also limited in their capability. We find reduced sensitivity to long duration signals compared to the excellent results for short-duration binary black hole signals.
Generation of fully spin-polarized currents in three-terminal graphene-based transistors

description: We propose three-terminal spin devices with graphene nanoribbons (terminals) and a graphene flake (channel) to generate a highly spin-polarized current without an external magnetic field or ferromagnetic electrodes. The Hubbard repulsion within the mean-field approximation plays the main role to separate the unpolarized electric current at the source terminal into spin-polarized currents at the drain terminals. It is shown that by modulating one of the drain voltages, a fully spin-polarized current can be generated in the other drain terminal. In addition, the geometry of the channel and the arrangement of edge atoms have significant impact on the efficiency of spin currents in the three-terminal junctions which might be utilized in generation of graphene-based spin transistors.

description: We study the application of one nanoring driven by a laser field in different states of polarization in logic circuits. In particular we show that assigning boolean values to different state of the incident laser field and to the emitted signals, we can create logic gates such as OR, XOR and AND. We also show the possibility to make logic circuits such as half-adder and full-adder using one and two nanoring respectively. Using two nanorings we made the Toffoli gate. Finally we use the final angular momentum acquired by the electron to store information and hence show the possibility to use an array of nanorings as a mass memory device.

description: Open access publishing represents an important change in the scientific publishing landscape.  The degree to which authors embrace the new publishing model will affect the rate of change in scholarly communication.  The stakeholders in this shift are many, but the two key groups invested in the success of open access publishing are the general public who funds science through taxes and the research community that relies on robust modes of communication to exchange and evaluate information. This survey examines government researchers at the National Institute of Environmental Health Sciences (NIEHS) and assesses the attitudes and understandings they have about open access publishing.

description: In this paper, a new re-initialization method for the conservative level-set function is put forward. First, it has been shown that the re-initialization and advection equations of the conservative level-set function are mathematically equivalent to the re-initialization and advection equations of the localized signed distance function. Next, a new discretization for the spatial derivatives of the conservative level-set function has been proposed. This new discretization is consistent with the re-initialization procedure and it guarantees a second-order convergence rate of the interface curvature on gradually refined grids. The new re-initialization method does not introduce artificial deformations to stationary and non-stationary interfaces, even when the number of re-initialization steps is large.

description: A proposed method for dealing with foreground emission in upcoming 21-cm observations from the epoch of reionization is to limit observations to an uncontaminated window in Fourier space. Foreground emission can be avoided in this way, since it is limited to a wedge-shaped region in $k_{\parallel}, k_{\perp}$ space. However, the power spectrum is anisotropic owing to redshift-space distortions from peculiar velocities. Consequently, the 21-cm power spectrum measured in the foreground avoidance window---which samples only a limited range of angles close to the line-of-sight direction---differs from the full spherically-averaged power spectrum which requires an average over \emph{all} angles. In this paper, we calculate the magnitude of this "wedge bias" for the first time. We find that the bias is strongest at high redshifts, where measurements using foreground avoidance will over-estimate the power spectrum by around 100 per cent, possibly obscuring the distinctive rise and fall signature that is anticipated for the spherically-averaged 21-cm power spectrum. In the later stages of reionization, the bias becomes negative, and smaller in magnitude ($\lesssim 20$ per cent). The effect shows only a weak dependence on spatial scale and reionization topology.

A typology of activities over a century of urban growth

Year: 2024
Subjects: subject: Physics and Society (physics.soc-ph)

description: Contemporary literature on the dynamics of economic activities in growing cities mainly focused on a few years or decades time frames. Using a new geo-historical database constructed from historical directories with about 1 million entries, we present a comprehensive analysis of the dynamics of activities in a major city, Paris, over almost a century (1829-1907). Our analysis suggests that activities that accompany city growth can be classified in different categories according to their dynamics and their scaling with population: (i) linear for everyday needs of residents (food stores, clothing retailers, health care practitioners), (ii) sublinear for public services (legal, administrative, educational), (iii) superlinear for the city's specific features (passing fads, specialization, timely needs). The dynamics of these activities is in addition very sensitive to historical perturbations such as large scale public works or political conflicts. These results shed light on the evolution of activities, a crucial component of growing cities.

description: We propose a new strategy to probe the $Z$ boson couplings to bottom and charm quarks at the LHC. In this work we mainly focus on the case of bottom quarks. Here, the $Z$ boson is produced in association with two $b$-jets and decays to electrons or muons. In this final state, tagging the charge of the $b$-jets allows us to measure the charge asymmetry and thus to directly probe the $Zb\bar{b}$ couplings. The leptonic final state not only allows us to cleanly reconstruct the $Z$ boson but also to mitigate the otherwise overwhelming backgrounds. Furthermore, while LEP could only scan a limited range of dilepton invariant masses, there is no such limitation at the LHC. Consequently, this allows us to make full use of the interference between the amplitudes mediated by a $Z$ boson and a photon. Using the full high-luminosity LHC dataset of $3~\text{ab}^{-1}$ and with the current flavor and charge-tagging capabilities would allow us to reject the wrong-sign right-handed coupling solution by 4$\sigma$. Further improving the charge-tagging efficiency would disfavor it by 6$\sigma$.

description: We study both analytically and numerically the edge of two-dimensional ferromagnets with Dzyaloshinskii-Moriya (DM) interactions, considering both chiral magnets and magnets with interface-induced DM interactions. We show that in the field-polarized ferromagnetic phase magnon states exist which are bound to the edge, and we calculate their spectra within a continuum field theory. Upon lowering an external magnetic field, these bound magnons condense at a finite momentum and the edge becomes locally unstable. Micromagnetic simulations demonstrate that this edge instability triggers the creation of a helical phase which penetrates the field-polarized state within the bulk. A subsequent increase of the magnetic field allows to create skyrmions close to the edge in a controlled manner.

description: In the latter half of the twentieth century, many countries in Latin America experienced brutal dictatorships marked by state-sponsored violence, persecution of left-leaning individuals and institutions, and most pertinent to this paper, suppression of ideas and information. After the fall of these dictatorships, cultural institutions struggled to administer to the needs of a population looking for answers and a way to move forward. With many "official" records destroyed or altered fundamentally, cultural institutions were forced to employ alternate methods of collection building, assessment, and sharing. These three case studies speak to the efforts employed by these institutions to adjust their policies and service to accommodate a different political landscape and patron base to achieve the goals of recreating public trust and moving forward as a nation in the wake of a dictatorship.

description: In new digital environments characterized by persistence, searchability and aggregatability, the temporal boundaries on socially shared information that individuals had previously been able to effectively regulate have weakened considerably. These changes create troubling implications for identity formation as expressions of identity that would have previously been gradually forgotten now have the potential to be rediscovered online by anyone at any time in the future. Individuals, through the use of semi-disposable pseudonyms, and institutions, through the use of a system of privacy-focused microdata, can begin to ameliorate the harms created by the affordance of digital technology while preserving the benefits.

Most available laboratory measurements have uncertainties much larger than this. We report a joint experimental and theoretical study providing rotation-vibration line intensities with the required accuracy. The {\it ab initio} calculations are extendible to all atmospherically important bands of CO$_2$ and to its isotologues. As such they will form the basis for detailed CO$_2$ spectroscopic line lists for future studies.

description: All natural things process and transform information. They receive environmental information as input, and transform it into appropriate output responses. Much of science is dedicated to building models of such systems -- algorithmic abstractions of their input-output behavior that allow us to simulate how such systems can behave in the future, conditioned on what has transpired in the past. Here, we show that classical models cannot avoid inefficiency -- storing past information that is unnecessary for correct future simulation. We construct quantum models that mitigate this waste, whenever it is physically possible to do so. This suggests that the complexity of general input-output processes depends fundamentally on what sort of information theory we use to describe them.

description: We point out that current calculations of inclusive two-particle correlations in p-A collisions based on the Color Glass Condensate approach exhibit a contribution from Hanbury-Brown-Twiss correlations. These HBT correlations are quite distinct from the standard ones, in that they are apparent for particles widely separated in rapidity. The transverse size of the emitter which is reflected in these correlations is the gluonic size of the proton. This raises an interesting possibility of measuring the proton size directly by the HBT effect of particle pairs produced in p-A collisions.

description: July 2002, SunSITE-MetaLab-ibiblio will celebrate ten years of existence. It has been an exciting decade, full of innovation and experimentation. During this time, the pendulum of information organization has swung from being driven by the technology to savoring the liberation of the new medium--back and forth, never lingering long. Usability, visual interest and technology have led the dance of the development of the digital archive. This paper is a case study of the SunSITE-MetaLab-ibiblio archive and the vision that allowed the archive to exist, as well as a record of the development of the SunSITE-MetaLab-ibiblio archive in relation to the trends of information organization of that time period. It is a collection of snapshots in the development of one of the world's first and largest digital archives.

description: Mathematical problems of digital terrain analysis include interpolation of digital elevation models (DEMs), DEM generalization and denoising, and computation of morphometric variables by calculation of partial derivatives of elevation. Traditionally, these procedures are based on numerical treatments of two-variable discrete functions of elevation. We developed a spectral analytical method and algorithm based on high-order orthogonal expansions using the Chebyshev polynomials of the first kind with the subsequent Fejer summation. The method and algorithm are intended for DEM analytical treatment, such as, DEM global approximation, denoising, and generalization as well as computation of morphometric variables by analytical calculation of partial derivatives. To test the method and algorithm, we used a DEM of the Northern Andes including 230,880 points (the elevation matrix 480 $\times$ 481). DEMs were reconstructed with 480, 240, 120, 60, and 30 expansion coefficients. The first and second partial derivatives of elevation were analytically calculated from the reconstructed DEMs. Models of horizontal curvature ($k_h$) were then computed with the derivatives. A set of elevation and $k_h$ maps related to different number of expansion coefficients well illustrates data generalization effects, denoising, and removal of artifacts contained in the original DEM. The test results demonstrated a good performance of the developed method and algorithm. They can be utilized as a universal tool for analytical treatment in digital terrain modeling.

Hybrid density functional study of optically active Er$^{3+}$ centers in GaN

Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Understanding the luminescence of GaN doped with erbium (Er) requires a detailed knowledge of the interaction between the rare-earth dopant and the nitride host, including intrinsic defects and other impurities that may be present in the host material. We address this problem through a first-principles hybrid density functional study of the structure, energetics, and transition levels of the Er impurity and its complexes with N and Ga vacancies, substitutional C and O impurities, and H interstitials in wurtzite GaN. We find that, in the interior of the material, Er$_{\rm Ga}$ is the dominant Er$^{3+}$ center with a formation energy of 1.55 eV; Er$_{\rm Ga}$-$V_{\rm N}$ possesses a deep donor level at 0.61 eV which can assist in the transfer of energy to the 4$f$-electron core. Multiple optically active Er$^{3+}$ centers are possible in Er-doped GaN.

description: We investigated whether outward Planetesimal Driven Migration (PDM) takes place or not in simulations when the self gravity of planetesimals is included. We performed $N$-body simulations of planetesimal disks with large width (0.7 - 4AU) which ranges over the ice line. The simulations consisted of two stages. The first stage simulations were carried out to see the runaway growth phase using the planetesimals of initially the same mass. The runaway growth took place both at the inner edge of the disk and at the region just outside the ice line. This result was utilized for the initial setup of the second stage simulations in which the runaway bodies just outside the ice line were replaced by the protoplanets with about the isolation mass. In the second stage simulations, the outward migration of the protoplanet was followed by the stopping of the migration due to the increase of the random velocity of the planetesimals. Due to this increase of random velocities, one of the PDM criteria derived in Minton and Levison (2014) was broken. In the current simulations, the effect of the gas disk is not considered. It is likely that the gas disk plays an important role in planetesimal driven migration, and we plan to study its effect in future papers.

Retrieval of LGBTQ+ Recreational Reading Material: A Comparative Study
Creators: name: Payne, Claire
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Over the past few decades, a sizeable body of library and information science literature has pointed to the inadequacies of traditional cataloging and classification systems for describing material related to marginalized communities. At the same time, alternative metadata systems have proliferated in online environments and social tagging has become almost ubiquitous. Focused specifically on the retrieval of LGBTQ+-related recreational reading materials, this study used an online survey to assess the utility of traditional library systems in comparison with the utility of the user-moderated folksonomy employed in the Archive of Our Own (AO3) fanwork repository. Results indicated that respondents, who were generally comfortable in both the library and Archive environments, preferred using AO3 to access LGBTQ+ material and perceived the tagging system to be of greater value in search processes than typical subject access mechanisms. Several possible avenues for improving current systems emerge in the conclusion of the paper.

description: This study analyzes circulation statistics gathered from five elementary school libraries in the Raleigh, Durham, and Chapel Hill regions of North Carolina of five children's books recently made into Blockbuster movies. The gathered circulation statistics were analyzed and graphed in regards to the book-based Blockbuster movies theatrical release date and mean number of checkouts. The findings of this study show a correlation between the theatrical release of the book-based Blockbuster movie and the number of times the book is checked-out. The mean number of checkouts illustrate that more children check the book out immediately following the release of the book-based Blockbuster movie than they do before the movie's theatrical release. As a result of data analysis, a trend illustrating the few months before the book-based Blockbuster movies theatrical release and immediately following the movie's theatrical release there is a surge in the number of times the book is checked-out.

description: In three papers Colbeck and Renner (Nature Communications 2:411, (2011); Phys. Rev. Lett. 108, 150402 (2012); arXiv:1208.4123) argued that "no alternative theory compatible with quantum theory and satisfying the freedom of choice assumption can give improved predictions". We give a more precise version of the formulation and proof of this remarkable claim. Our proof broadly follows theirs, which relies on physically well motivated axioms, but to fill in some crucial details certain technical assumptions have had to be added, whose physical status seems somewhat obscure.

description: In this paper, we studied the $ργ^* \to π$ and $ργ^*\to ρ$ transition processes and made the calculations for the $ρπ$ transition form factor $Q^4 F_{ρπ}(Q^2)$ and the $ρ$ meson electromagnetic form factors, $F_{\rm LL, LT,TT}(Q^2)$ and $F_{1,2,3}(Q^2)$, by employing the perturbative QCD (PQCD) factorization approach. For the $ργ^* \to π$ transition, we found that the contribution to form factor $Q^4 F_{ρπ}(Q)$ from the term proportional to the distribution amplitude combination $ϕ^T_ρ(x_1)ϕ^P_π(x_2)$ is absolutely dominant, and the PQCD predictions for both the size and the $Q^2$-dependence of this form factor $Q^4 F_{ρπ}(Q^2)$ agree well with those from the extended ADS/QCD models or the light-cone QCD sum rule. For the $ργ^* \to ρ$ transition and in the region of $Q^2\geq 3$ GeV$^2$, further more, we found that the PQCD predictions for the magnitude and their $Q^2$-dependence of the $F_1(Q^2)$ and $F_2(Q^2)$ form factors agree well with those from the QCD sum rule, while the PQCD prediction for $F_3(Q^2)$ is much larger than the one from the QCD sum rule.

description: This study describes how African-American students use and  perceive the library within the  Sonja Haynes Stone Center  for  Black  Culture and its  impact on their undergraduate experience. On the campus of  the University of North  Carolina at Chapel Hill, six interviews were done with undergraduate students ranging in ages from 18-22 and across classifications.
Students generally found the  library as an important space, but there  is  some hesitancy as to whether it  is  an important part of the  black experience as an undergraduate. They took value in  the  history and culture preserved  in  the  space, and  felt welcome when  visiting. Students are also split when deciding whether they would be willing to fight to support the  space and feel that  it  should be better utilized.
Using Social Media in Cultural Institutions to Encourage Higher Use Among America's Minority Population

Subjects: Social media
Minorities
Cultural institutions

description: Cultural institutions like museums, libraries and archives are and have been
experiencing low numbers in usage and visitation among minority populations.
The number of minorities taking advantage of services provided by these
institutions has become significantly important due to recent growth in minority
populations. This new growth rate has surpassed that of the Non-Hispanic
Caucasian population, the traditional audience base for cultural institutions.
Efforts made in the past couple of decades to encourage minorities to pursue
careers in museums, libraries and archives have not been as productive as
hoped. One solution to this issue may be found in new technologies that have
emerged in the new millennium. If cultural institutions were to take advantage of
some of the marketing techniques using social media, this may just give them the
tools they need to attract and encourage higher participation from America's
minority population.
