description: Recent imaging of protoplanetary disks with high resolution and contrast have revealed a striking variety of substructure. Of particular interest are cases where near-infrared scattered light images show evidence for low-intensity annular "gaps." The origins of such structures are still uncertain, but the interaction of the gas disk with planets is a common interpretation. We study the impact that the evolution of the solid material can have on the observable properties of disks in a simple scenario without any gravitational or hydrodynamical disturbances to the gas disk structure. Even with a smooth and continuous gas density profile, we find that the scattered light emission produced by small dust grains can exhibit ring-like depressions similar to those presented in recent observations. The physical mechanisms responsible for these features rely on the inefficient fragmentation of dust particles. The occurrence and position of the proposed "gap" features depend most strongly on the dust-to-gas ratio, the fragmentation threshold velocity, the strength of the turbulence, and the age of the disk, and should be generic (at some radius) for typically adopted disk parameters. The same physical processes can affect the thermal emission at optically thin wavelengths ($\sim$1 mm), although the behavior can be more complex; unlike for disk-planet interactions, a "gap" should not be present at these longer wavelengths.

Youth Should be Seen and Heard: A Case Study in Youth Activism in Public Libraries
Creators: name: Soder, Brittany
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: According to the US Census Bureau (2016), youth make up 22% of our population. Despite making up such a large portion of our population, teens are oftentimes expected to sit quietly, with no place in society to make a difference. As a part of the larger community, the public library is an optimum place for teens to gain important leadership and advocacy skills. This case study looks at how and why librarians throughout the United States are incorporating activist-focused programs and events for their youth. Interviews were conducted and coded for themes that emerged from connected learning theory and critical social youth empowerment theory. The results suggest that librarians must first understand the whole community they serve, cultivate relationships with youth, and allow for interest driven programming. These suggestions lay the groundwork for further youth activist work in libraries.

description: Sampling of physical fields with mobile sensor is an emerging area. In this context, this work introduces and proposes solutions to a fundamental question: can a spatial field be estimated from samples taken at unknown sampling locations? Unknown sampling location, sample quantization, unknown bandwidth of the field, and presence of measurement-noise present difficulties in the process of field estimation. In this work, except for quantization, the other three issues will be tackled together in a mobile-sampling framework. Spatially bandlimited fields are considered. It is assumed that measurement-noise affected field samples are collected on spatial locations obtained from an unknown renewal process. That is, the samples are obtained on locations obtained from a renewal process, but the sampling locations and the renewal process distribution are unknown. In this unknown sampling location setup, it is shown that the mean-squared error in field estimation decreases as $O(1/n)$ where $n$ is the average number of samples collected by the mobile sensor. The average number of samples collected is determined by the inter-sample spacing distribution in the renewal process. An algorithm to ascertain spatial field's bandwidth is detailed, which works with high probability as the average number of samples $n$ increases. This algorithm works in the same setup, i.e., in the presence of measurement-noise and unknown sampling locations.

description: This study describes a survey of the students, faculty, and staff of the University of North Carolina at Chapel Hill regarding awareness of E911 and LBS technologies on cellular phones and how this awareness relates to perceptions of privacy. Responses to the survey showed generally low awareness of E911 and LBS technologies, but also revealed unexpected privacy distinctions. Some respondents viewed their cellular phones as private, but not the conversations or text messages. Other respondents were just the opposite, viewing their conversations and text message as private, but not the phones. Though LBS can broadcast a cellular phone's location anytime the phone is powered on, even those users that appear to control their privacy the most tend to leave their phones on for long periods of time, indicating either a lack of awareness regarding location privacy, or a lack of concern.
A Review of Subject Indexing and Social Tagging Projects in Art Museums.

description: Studies show that art historians and other image professionals value being able to search for images using subject terms. However, the subject indexing of artworks and images is a subjective and time-consuming undertaking. As a result, many digital image collections are lacking comprehensive subject access points at the object level. Social tagging of digital images has been proposed as a means of improving image metadata and increasing subject access to art images. Three social tagging projects, Steve.museum, the Brooklyn Museum Posse, and Art UK’s Your Paintings Tagger, were created as test programs to explore issues regarding the social tagging of digital images in museum collections. Their results suggest that carefully designed tagging programs can improve access to art images when used as a supplement to professional indexing.

Let $S$ be any "curved" submanifold of small codimension of a maximal horospherical subgroup of $G$ relative to an $\mathbb R$-diagonalizable element $a$ in the diagonal of $G$. Then for $S$ compact our result can be described by saying that $a^n \text{vol}_S$ converges in an effective way to the volume measure of $G/Γ$ when $n\to \infty$, with $\text{vol}_S$ the volume measure on $S$.

description: The purpose of this research was to analyze the periodical collections of public libraries in the Triangle region of North Carolina in terms of young adult titles. Research questions targeted how public librarians provide their young adult patrons with access to periodical collections, address access to periodicals available through the Internet and develop periodical collections in response to research findings on young adult reading. Collections were evaluated in terms of collection policies, placement, reference to other collections, and content. While the research revealed that collections varied in terms of responses to several of the research concerns, the collections showed some consistency in terms of collection policy and response to research findings.

description: This white paper examines the benefit of the upcoming James Webb Space Telescope for studies of the Solar System's four giant planets: Jupiter, Saturn, Uranus, and Neptune. JWST's superior sensitivity, combined with high spatial and spectral resolution, will enable near- and mid-infrared imaging and spectroscopy of these objects with unprecedented quality. In this paper we discuss some of the myriad scientific investigations possible with JWST regarding the giant planets. This discussion is preceded by the specifics of JWST instrumentation most relevant to giant planet observations. We conclude with identification of desired pre-launch testing and operational aspects of JWST that would greatly benefit future studies of the giant planets.

description: Evidence Based Practice (EBP) is a relatively new approach that professionals are using to cope with the ever-growing body of literature in their fields. The goal of EBP is to effectively use this body of literature to improve professional practice, thus improving the quality of services. A major component of EBP is asking a focused, well-built question, referred to in this paper as an Evidence Based Practice Question (EBPQ). This paper reports the findings of an exploratory study that examines the use an EBPQ to respond to reference questions emailed to a university library reference desk. A purposive sample of 30 randomly selected reference emails was divided into two groups, the EBPQ group and the control group. The professional searcher who conducted the searches used the same approach in responding to each emailed reference question, except that the EBPQ group searches were guided by EBPQs, and the control group's responses were not. The results indicate that searches guided by using EBPQs are more focused, apply more resources to the search process, and take less time than searches not guided by using EBPQs. These conclusions suggest that EBPQs appear to be useful for improving that search process and that further research is warranted.

description: Migrating birds flexibly adjust their individual migratory decisions, i.e. departing, routing and landing, based on intrinsic (e.g. energy stores) and extrinsic (e.g. landscape features and weather) factors modulating the endogenous stimuli. So far, these decisions have mostly been studied separately. Notably, we lack information on which factors landing decisions during active flight are based on. Therefore, we simultaneously recorded all three decisions in free-flying long-distance migratory songbirds in a coastal stopover area via regional-scale radio-telemetry and related them to the prevailing weather. Birds departed under favourable weather conditions resulting in specific nights with increased departure probability. Once departed, birds could either fly offshore or take a route along the coast, which was predicted by wind support. Radio-tracking revealed that departed individuals more likely interrupted their migratory endurance flight under overcast or headwind conditions. Studying departure, routing and landing decisions in concert, we highlight the importance of weather as a common driver across all migratory decisions. By radio-tracking individuals between stopovers, we provide evidence that avoidance of adverse weather conditions is an important function of stopover. Understanding how birds adjust migratory decisions and how they affect the timing of migration and survival is key to link migration performance to individual fitness.

description: We present a modelling framework, and basic model parameterization, for the study of DNA origami folding at the level of DNA domains. Our approach is explicitly kinetic and does not assume a specific folding pathway. The binding of each staple is associated with a free-energy change that depends on staple sequence, the possibility of coaxial stacking with neighbouring domains, and the entropic cost of constraining the scaffold by inserting staple crossovers. A rigorous thermodynamic model is difficult to implement as a result of the complex, multiply connected geometry of the scaffold: we present a solution to this problem for planar origami. Coaxial stacking and entropic terms, particularly when loop closure exponents are taken to be larger than those for ideal chains, introduce interactions between staples. These cooperative interactions lead to the prediction of sharp assembly transitions with notable hysteresis that are consistent with experimental observations. We show that the model reproduces the experimentally observed consequences of reducing staple concentration, accelerated cooling and absent staples. We also present a simpler methodology that gives consistent results and can be used to study a wider range of systems including non-planar origami.

description: Recently, librarians have struggled to understand their relationship to a new breed of Web services that, like libraries, connect users with the information they need. These services, known as Web 2.0, offer new service models, methods, and technologies that can be adapted to improve library services. Additionally, these services affect library users' information seeking behaviors, communication styles, and expectations. The term Library 2.0 has been introduced into the professional language of librarianship as a way to discuss these changes. This paper works to establish a theoretical foundation of Library 2.0 in academic libraries, or Academic Library 2.0.

description: We recently defined an invariant of contact manifolds with convex boundary in Kronheimer and Mrowka's sutured monopole Floer homology theory. Here, we prove that there is an isomorphism between sutured monopole Floer homology and sutured Heegaard Floer homology which identifies our invariant with the contact class defined by Honda, Kazez and Matić in the latter theory. One consequence is that the Legendrian invariants in knot Floer homology behave functorially with respect to Lagrangian concordance. In particular, these invariants provide computable and effective obstructions to the existence of such concordances. Our work also provides the first proof which does not rely on the relative Giroux correspondence that the vanishing or non-vanishing of Honda, Kazez and Matić's contact class is a well-defined invariant of contact manifolds.

A New Constraint on the Physical Nature of Damped Lyman Alpha Systems

Year: 2015
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: The formation and evolution of galaxies require large reservoirs of cold, neutral gas. The damped Lya systems (DLAs), seen in absorption towards distant quasars and gamma-ray bursts, are predicted to be the dominant reservoirs for this gas. Detailed properties of DLAs have been studied extensively for decades with great success. However, their size, fundamental in understanding their nature, has remained elusive, as quasar and gamma-ray-burst sightlines only probe comparatively tiny areas of the foreground DLAs. Here, we introduce a new approach to measure the full extent of DLAs in the sightlines toward extended background sources. We present the discovery of a high-column-density (log N(HI) = 21.1 +/-0.4 cm^-2) DLA at z ~ 2.4 covering 90-100% of the luminous extent of a line-of-sight background galaxy. Estimates of the size of the background galaxy range from a minimum of a few kpc^2, to ~100 kpc^2, and demonstrate that high-column density neutral gas can span continuous areas 10^8 - 10^10 times larger than previously explored in quasar or gamma-ray burst sightlines. The DLA presented here is the first from a sample of DLAs in our pilot survey that searches Lyman break and Lyman continuum galaxies at high redshift. The low luminosities, large sizes, and mass contents (>~10^6 - 10^9 M_solar) implied by this DLA and the early data suggest that DLAs contain the necessary fuel for galaxies, with many systems consistent with relatively massive, low-luminosity primeval galaxies.

description: We use mid-infrared 3.6 and 4.5microns imaging of NGC 3906 from the Spitzer Survey of Stellar Structure in Galaxies (S4G) to understand the nature of an unusual offset between its stellar bar and the photometric center of an otherwise regular, circular outer stellar disk. We measure an offset of ~720 pc between the center of the stellar bar and photometric center of the stellar disk; the bar center coincides with the kinematic center of the disk determined from previous HI observations. Although the undisturbed shape of the disk suggests that NGC 3906 has not undergone a significant merger event in its recent history, the most plausible explanation for the observed offset is an interaction. Given the relatively isolated nature of NGC 3906 this interaction could be with dark matter sub structure in the galaxy's halo or from a recent interaction with a fast moving neighbor which remains to be identified. Simulations aimed at reproducing the observed offset between the stellar bar / kinematic center of the system and the photometric center of the disk are necessary to confirm this hypothesis and constrain the interaction history of the galaxy.

description: This study describes the investigation of library web pages and online catalogs of fifty libraries across the United States. The investigator compared the online catalog records for two serial titles. Comparisons were made concerning the level of holdings statement used by the library, the availability of MARC records, links to related titles, and how the electronic version of the serial could be accessed. Results show that many of the library catalogs contain records fully detailing both descriptive elements and extensive local holdings information. Many libraries also maintain more than one way to access the electronic version of a serial. Although access to electronic resources was available in the majority of libraries studied, the variety of methods used to access these resources can cause confusion among users. Several suggestions for more user-friendly systems are discussed.

These developments influence resource utilization, extravehicular activities, planetary surface exploration, long-duration space missions, and colonization. Robots improve research, productivity, and astronaut safety but present problems. Highlighting research and knowledge gaps. Space ethics, human-robot interaction, and failure recovery are gaps. This extensive study showed how robots and autonomous systems may transform space exploration and colonization. Researchers, engineers, and mission planners may benefit. Robotics and autonomy will improve space exploration.

description: Fe and Al are two of the most important rock-forming elements other than Mg, Si, and O. Their presence in the lower mantle's most abundant minerals, MgSiO_3 bridgmanite, MgSiO_3 post-perovskite and MgO periclase, alters their elastic properties. However, knowledge on the thermoelasticity of Fe- and Al-bearing MgSiO_3 bridgmanite, and post-perovskite is scarce. In this study, we perform ab initio molecular dynamics to calculate the elastic and seismic properties of pure, Fe^{3+}- and Fe^{2+}-, and Al^{3+}-bearing MgSiO_3 perovskite and post-perovskite, over a wide range of pressures, temperatures, and Fe/Al compositions. Our results show that a mineral assemblage resembling pyrolite fits a 1D seismological model well, down to, at least, a few hundred kilometers above the core-mantle boundary, i.e. the top of the D'' region. In D'', a similar composition is still an excellent fit to the average velocities and fairly approximate to the density. We also implement polycrystal plasticity with a geodynamic model to predict resulting seismic anisotropy, and find post-perovskite with predominant (001) slip across all compositions agrees best with seismic observations in the D''.

integrity issues in specific demographics, such as international and transfer
students, suggest that our definitions of plagiarism and academic integrity are
potentially culturally bound and cannot be simply transferred through submitting to
an honor code. UNC-CH's R.B. House Undergraduate Library and the Office of
Student Conduct have partnered to create a plagiarism tutorial that better meets the
challenges of changing information uses in education and offers a more inclusive
approach to academic integrity education. This tutorial focuses on skill development
and uses methods and concepts prevalent in pedagogical theory to help students
develop a better understanding of the issues surrounding plagiarism.

description: We report inelastic neutron scattering measurements over 7-1251 K in CaMnO3 covering various phase transitions, and over 6-150 K in PrMnO3 covering the magnetic transition. The excitations around 20 meV in CaMnO3 and at 17 meV in PrMnO3 are found to be associated with magnetic origin. In spite of similarity of the structure of the two compounds, the neutron inelastic spectrum of PrMnO3 exhibits broad features at 150 K unlike well-defined peaks in the spectrum of CaMnO3. This might result from the difference in nature of interactions in the two compounds (magnetic and Jahn-Teller distortion). The interpretation and analysis of the observed phonon spectra have been performed using ab-initio phonon calculations. We also discuss the effect of pressure on the structural distortions in the orthorhombic phase of CaMnO3 and PrMnO3. On application of pressure, we found that the variations of Mn-O distances are isotropic for CaMnO3 and highly anisotropic for PrMnO3. The calculated structure as a function of pressure in PrMnO3 shows that suppression of Jahn-Teller distortion and insulator to metal transition occurs simultaneously. Our calculations show that this transition may not be associated with the occurrence of the tetragonal phase above 20 GPa as reported in the literature, since the tetragonal phase is found to be dynamically unstable although it is found to be energetically favored over the orthorhombic phase above 20 GPa. CaMnO3 does not show any phase transition up to 60 GPa.

description: The social network analysis (SNA), branch of complex systems can be used in the construction of multiagent systems. This paper proposes a study of how social network analysis can assist in modeling multiagent systems, while addressing similarities and differences between the two theories. We built a prototype of multi-agent systems for resolution of tasks through the formation of teams of agents that are formed on the basis of the social network established between agents. Agents make use of performance indicators to assess when should change their social network to maximize the participation in teams

description: In the 1920s and early 1930s, public libraries in South Carolina were among the most underfunded and poorly administered in the United States. Since Jim Crow laws were still in effect, only white citizens had access to public library facilities in many parts of the state. After the Works Progress Administration (WPA) began its Library Demonstration Project in 1933, library conditions improved drastically. However, the WPA effort accomplished relatively little for the state's black population. It was not until the 1950s and 1960s that black South Carolinians began making significant progress toward gaining access to public library services. This paper examines the evolution of public library services in South Carolina from the 1930s to the 1960s, treating the development of services for blacks and the development of services for whites as largely distinct processes.

Segue 1 - A Compressed Star Formation History Before Reionization

description: Segue 1 is the current best candidate for a "first galaxy", a system which experienced only a single short burst of star formation and has since remained unchanged. Here we present possible star formation scenarios which can explain its unique metallicity distribution. While the majority of stars in all other ultra-faint dwarfs (UFDs) are within 0.5 dex of the mean [Fe/H] for the galaxy, 5 of the 7 stars in Segue 1 have a spread of $Δ$[Fe/H] $>0.8$ dex. We show that this distribution of metallicities canot be explained by a gradual build-up of stars, but instead requires clustered star formation. Chemical tagging allows the separate unresolved delta functions in abundance space to be associated with discrete events in space and time. This provides an opportunity to put the enrichment events into a time sequence and unravel the history of the system. We investigate two possible scenarios for the star formation history of Segue 1 using Fyris Alpha simulations of gas in a $10^7$ M$_\odot$ dark matter halo.

Survey of Higgs interpretations of the diboson excesses

description: We investigate diboson signals in the Standard Model (SM) with an extended Higgs sector, motivated by the excesses in the diboson channels at the LHC. We begin with the unitarity sum-rules of the weak gauge boson scattering assuming the Higgs sector is extended. According to the sum-rules, we discuss the Higgs interpretations of the diboson signals and the consistency with the ATLAS diboson anomaly and other experimental constraints. As a concrete example, we propose a two-Higgs-doublet model where the Yukawa coupling of an extra CP-even scalar with up-type quark is relatively large. The diboson (WW and ZZ) signals can be explained by 2 TeV CP-even Higgs boson, while the partners, the CP-odd and the charged Higgs bosons in the extra doublet, are severely constrained by both the LHC direct search and the indirect search via flavor observables. Especially, in order to avoid the diboson resonance search in the Vh channel, further extensions of the model are required. The diboson excess is correlated with the SM Higgs signals in our framework, so that the precise measurement of the SM Higgs boson is also important to test the Higgs interpretation.

description: The value of the tensor-to-scalar ratio $r$ in the region allowed by the latest $Planck$ 2015 measurements can be associated to a large variety of inflationary models. We discuss here the potential of future Cosmic Microwave Background cosmological observations in disentangling among the possible theoretical scenarios allowed by our analyses of current $Planck$ temperature and polarization data. Rather than focusing only on $r$, we focus as well on the running of the primordial power spectrum, $α_s$ and the running of thereof, $β_s$. Our Fisher matrix method benefits from a detailed and realistic appraisal of the expected foregrounds. Future cosmological probes, as the COrE mission, may be able to reach an unprecedented accuracy in the extraction of $β_s$ and rule out the most favoured inflationary models.

description: XHTML is an innovative metadata standard that blends the traditional World Wide Web markup language HTML with the less well-known markup language XML. It is currently only used in a small percentage of documents on the Web. The purpose of this paper is take a look at what sort of penetration XHTML has achieved to date, and make a preliminary effort at mapping the diffusion process of this innovation. To this end, I developed three categories of web page to examine, online shops, personal homepages, and university academic library homepages. I then proceeded to collect the URLs and document types (HTML or XHTML) of seventy-five web pages for each category. I also examined archived data to determine the approximate implementation date for those pages that had adopted XHTML. Using this data, I drew some preliminary conclusions about the state of diffusion in which XHTML is currently, as well as identifying which areas will require further study in future works.

description: This paper explains how to obtain the distribution function of minority ions in tokamak plasmas using the Monte Carlo method. Since the emphasis is on energetic ions, the guiding-center transformation is outlined, including also the transformation of the collision operator. Even within the guiding-center formalism, the fast particle simulations can still be very CPU intensive and, therefore, we introduce the reader also to the world of high-performance computing. The paper is concluded with a few examples where the presented method has been applied.

Who Will Teach Their History?: An Examination of the Use of Archival Holocaust Material In College Classrooms Throughout The United States
Creators: name: Overstreet, Jennifer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The archival community stresses the importance of teaching with primary sources as well as engaging with professors to encourage their use of archival materials, yet little research has been done from the perspective of the educator. Simultaneously, Holocaust scholars and educators argue the importance of utilizing primary source materials when teaching about Holocaust history, though the scope and extent to which professors use these materials is unknown. This study was conducted to examine the use of archival Holocaust material from the perspective of current Holocaust history educators in colleges and universities throughout the United States. A survey consisting a total of 23 questions was sent to 143 candidates; 20 responded as ineligible, and 52 completed the survey. Questions asked the participants what types of archival materials they use, from which Memory Institutions they were acquired, and how the materials were used by respondents in courses. Additional questions pertained to archives specifically, including the use of collections, contact and experiences with archivists and librarians, as well as experiences obtaining archival materials and any obstacles faced when attempting to access these materials. The study found that almost all of the professors use at least two different types of archival material in their courses and most consistently use archival materials that are visually and emotionally engaging, and that experiences with Memory Institutions as well as archivists are typically positive. The majority of respondents indicated encountering minimal, if any, obstacles when attempting to access archival materials.
