description: We study the interplay between large-spin, spin-orbit coupling, and superfluidity for bosons in a two dimensional optical lattice, focusing on the spin-1 spin-orbit coupled system recently realized at the Joint Quantum Institute [Campbell et. al., arXiv:1501.05984]. We find a rich quantum phase diagram, where, in addition to the conventional phases ---superfluid and insulator--- contained in the spin-$1$ Bose-Hubbard model, there are new lattice symmetry breaking phases. For weak interactions, the interplay between two length scales, the lattice momentum and the spin-orbit wave-vector induce a phase transition from a uniform superfluid to a phase where bosons simultaneously condense at the center and edge of the Brillouin zone at a non-zero spin-orbit strength. This state is characterized by spin density wave order, which arises from the spin-$1$ nature of the system. Interactions suppress spin density wave order, and favor a superfluid \textit{only} at the Brillouin zone edge. This state has spatially oscillating mean field order parameters, but a homogeneous density. We show that the spin density wave superfluid phase survives in a two dimensional harmonic trap, and thus establish that our results are directly applicable to experiments on $^{87}$Rb, $^7$Li, and $^{41}$K.

description: Maternal sleep and circadian health during pregnancy are emerging as important predictors of pregnancy outcomes, but examination of potential epigenetic mechanisms is rare. We investigated links between maternal leukocyte DNA methylation of circadian genes and birth outcomes within a pregnancy cohort. Women (n = 96) completed a questionnaire and provided a blood sample at least once during early-to-mid pregnancy (average gestation weeks = 14.2). Leukocyte DNA was isolated and DNA methylation (average percent of methylation) at multiple CpG sites within BMAL1, PER1, and MTNR1B genes were quantified by pyrosequencing. Birth outcomes including gestational age at delivery, birthweight, and head circumference were abstracted from medical charts. Linear regression analyses were run between each CpG site with birth outcomes, adjusting for important confounders. Sleep duration and timing were assessed as secondary exposures. Higher methylation of a CpG site in PER1 was associated with smaller log-transformed head circumference (β=-0.02 with 95% CI −0.02 to 0.01; P, trend = 0.04). Higher methylation of MTNR1B (averaged across sites) was associated with lower log-transformed birthweight (−0.08 with 95% CI −0.16 to −0.01; P, trend = 0.0495). In addition, longer sleep duration was associated with higher birthweight (0.10 with 95% CI 0.02 to 0.18 comparing > 9 h to < 8 h; P, trend = 0.04). This pilot investigation revealed that higher methylation of PER1 and MTNR1B genes, and sleep duration measured in early-to-mid pregnancy were related to birth outcomes.

description: Five-week-old moso bamboo (Phyllostachys edulis) seedlings from a single inbred plant were treated with heat stress at 42 degree centigrade for six hours, cold stress at 4 degree centigrade for sixteen hours, UV radiation under UV lamp (100 microwatt/cm2 and 50 cm distance to plant) for two hours, and salt stress by irrigating with 200 mM NaCl for three days. The seedlings grown at 25 degree centigrade with water irrigation were used as the control. The first three leaves from the top were collected. Calli generated from immature embryo of moso bamboo seeds were cultured in a medium containing 500 mg/L proline, 500 mg/L glutamine, 300 mg/L casein hydrolysate, 2 mg/L 2, 4-D, 0.1 mg/L zeatin, 30 g/L sucrose, and 8.0 g/L agar. Shoots of rapid growth stages were sampled at the 15th, 24th and 41st internodes, corresponding to the phases of initiation of cell division, rapid cell division and rapid cell elongation, respectively. The intercalary meristems in node slots at the early coloring stages (24th internode) were sampled from two internode color variation types, P. edulis f. luteosulcata (internode with yellow stripes) and P. edulis f. viridisulcata (internode with green stripes), and the wild type of moso bamboo. The intercalary meristems in shrunk and stretched parts of 15th twisted nodes, respectively, were sampled from an internode form mutation type (P. edulis cv. heterocycla) of moso bamboo with tortoise-shell-like internodes. In the meantime, the corresponding tissues of wild type moso bamboo were collected as the control group. All treatments and tissues were sampled with three biological replicates.

description: Mechanical metamaterials are engineered materials that gain their remarkable mechanical properties, such as negative Poisson's ratios, negative compressibility, phononic bandgaps, and topological phonon modes, from their structure rather than composition. Here we propose a new design principle, based on a uniform soft deformation of the whole structure, to allow metamaterials to be immediately and reversibly transformed between states with contrasting mechanical and acoustic properties. These properties are protected by the topological structure of the phonon band of the whole structure and are thus highly robust against disorder and noise. We discuss the general classification of all structures that exhibit such soft deformations, and provide specific examples to demonstrate how to utilize soft deformations to transform a system between different regimes such that remarkable changes in their properties, including edge stiffness and speed of sound, can be achieved.

School librarians--North Carolina

description: This study describes a questionnaire survey of school librarians in North Carolina who have received advanced certification from the National Board of Professional Teaching Standards. The survey was conducted to identify the transformational leadership practices of these school librarians and assess their ability to implement professional leadership guidelines.
School librarians’ leadership practices were assessed using the Leadership Practices Inventory, 3rd Edition (LPI). School librarians perceived themselves as possessing a high level of transformational leadership in the five exemplary practices identified by the LPI: Modeling the Way (MTW), Inspiring a Shared Vision (ISV), Challenging the Process (CTP), Enabling Others to Act (EOA) and Encouraging the Heart (ETH). They perceived themselves as being very strong at MTW and EOA. They were less successful at ISV and CTP. Overall, they were very successful in implementing professional leadership guidelines. Successful implementation of these guidelines was highly correlated with ISV and CTP.

description: This study presents the results of a usability test of reusable learning objects currently in development in the Instructional Services Department of the UNC-Chapel Hill University Library. The learning objects are Web-based learning modules that are part of a new project, Stories of the American South, and they aim to make digital primary source material more accessible by breaking it into manageable units and providing contextual information. Seven undergraduate students viewed three prototypes, each focused on a unique theme related to the history of the American South. The results suggested that the learning objects are generally usable in design and function, and participants' responses to design and content were positive. Several changes are suggested to optimize the usability of the learning object prototypes, and further usability testing with other audiences is recommended.

description: Parenthood is a significant life transition with considerable impacts on parent, child and family wellbeing. While life-enhancing, it is also stressful. New parents’ often hold unrealistic expectations and do not prepare adequately for the new role. Applying a critical exploratory Grounded Theory approach, this study explores the reasons for expectant parents’ unrealistic expectations. Thirty parents were interviewed about their preconceptions of parenthood, how they impacted on early parenting experiences and what, if anything, might help better prepare parents for this role. Participants reported unrealistic expectations, a lack of preparation, and recommended that parenting information be provided by professionals prenatally to help prevent adverse effects. In addition, we advocate promoting critical thinking to help parents identify and grapple with facets of social life that support and impede the way they experience and cope with parenthood, leading to the capacity to challenge cultural pressures that may make parenting even more difficult.

We restrict ourselves to the case where only the positive part of the spectrum gives a contribution to the sum in partition function. We give the analytical results for high temperatures.

description: In this study, collections in K-8 public school libraries across North Carolina were analyzed with respect to their holdings of items for Hispanic students. These collections were analyzed through online library catalogs, which were identified by visiting the websites of every public school district in North Carolina, along with school websites within those districts. 35 schools were randomly selected for further analysis. A pre-set group of keywords was used to search each catalog, and items that met specified criteria to qualify as Hispanic resources were recorded. This data has been used to analyze the collections of the schools with respect to total resources, resource format, resource language, and student population demographics (specifically, the percentage of Hispanic students within the respective schools). It is hoped that this research will lead to a better understanding of the resources available to Hispanic students in the K-8 public schools of North Carolina.

Influence of Rashba spin-orbit coupling on the Kondo effect

description: An Anderson model for a magnetic impurity in a two-dimensional electron gas with bulk Rashba spin-orbit interaction is solved using the numerical renormalization group under two different experimental scenarios. For a fixed Fermi energy, the Kondo temperature T_K varies weakly with Rashba coupling α, as reported previously. If instead the band filling is low and held constant, increasing αcan drive the system into a helical regime with exponential enhancement of T_K. Under either scenario, thermodynamic properties at low temperatures T exhibit the same dependences on T/T_K as are found for α= 0. Unlike the conventional Kondo effect, however, the impurity exhibits static spin correlations with conduction electrons of nonzero orbital angular momentum about the impurity site. We also consider a magnetic field that Zeeman splits the conduction band but not the impurity level, an effective picture that arises under a proposed route to access the helical regime in a driven system. The impurity contribution to the system's ground-state angular momentum is found to be a universal function of the ratio of the Zeeman energy to a temperature scale that is not T_K (as would be the case in a magnetic field that couples directly to the impurity spin), but rather is proportional to T_K divided by the impurity hybridization width. This universal scaling is explained via a perturbative treatment of field-induced changes in the electronic density of states.

description: The purpose of this study is to better understand the motivations that bring anarchists to librarianship and the different ways their political convictions impact library practice and work-life, including the extent to which the job accommodates or compromises radical politics. Three radical librarians were interviewed according to a semi-structured question schedule. Interviews were transcribed and analyzed using Stake's cross-case protocol, which yields themes common to all cases by comparing them against each other for commonalities, divergences, and patterns in participant responses. Results showed that all three participants were drawn to librarianship due to its strong service orientation and consonance with their activist work. Difficulties included the tensions inherent in managing others and participating within large group structures that impede direct action. This study draws attention to the shortfall of research on the praxis of this unique population within the profession and recommends directions for future investigation.

description: InGaN is an ideal alloy system for optoelectronic devices due its tunable band gap. Yet high-quality InGaN requires high In concentration, which is a challenging issue that limits its use in green-light LEDs and other devices. In this paper, we investigated the surfactant effect of Sb on the In incorporation on InGaN (000-1) surface via first-principles approaches. Surface phase diagram was also constructed to determine surface structures under different growth conditions. By analyzing surface stress under different structures, we found that Sb adatom can induce tensile sites in the cation layer, enhancing the In incorporation. These fi ndings may provide fundamental understandings and guidelines for the growth of InGaN with high In concentration.

description: An online tutorial for training volunteers at the Women's Health Information Center (WHIC) at the Women's Hospital at the University of North Carolina at Chapel Hill was created. It was intended to be understood by all adult age groups from any walk of life for such complex topics as the reference interview, ethics, and evaluating online health information. Usability testing was conducted using "think aloud" protocols and a questionnaire. This study identified specific aspects of the WHIC tutorial that can be improved, such as creating consistent links, clarifying terms and phrases, and adding more sample conversation dialogs. This study has implications for tutorial design generally, because certain aspects of this tutorial worked very well for learning, such as the sample conversation dialogs, and the lesson opening statements, summaries and exercise reviews.
Fifty Years of MIMO Detection: The Road to Large-Scale MIMOs

description: The emerging massive/large-scale MIMO (LS-MIMO) systems relying on very large antenna arrays have become a hot topic of wireless communications. Compared to the LTE based 4G mobile communication system that allows for up to 8 antenna elements at the base station (BS), the LS-MIMO system entails an unprecedented number of antennas, say 100 or more, at the BS. The huge leap in the number of BS antennas opens the door to a new research field in communication theory, propagation and electronics, where random matrix theory begins to play a dominant role. In this paper, we provide a recital on the historic heritages and novel challenges facing LS-MIMOs from a detection perspective. Firstly, we highlight the fundamentals of MIMO detection, including the nature of co-channel interference, the generality of the MIMO detection problem, the received signal models of both linear memoryless MIMO channels and dispersive MIMO channels exhibiting memory, as well as the complex-valued versus real-valued MIMO system models. Then, an extensive review of the representative MIMO detection methods conceived during the past 50 years (1965-2015) is presented, and relevant insights as well as lessons are inferred for designing complexity-scalable MIMO detection algorithms that are potentially applicable to LS-MIMO systems. Furthermore, we divide the LS-MIMO systems into two types, and elaborate on the distinct detection strategies suitable for each of them. The type-I LS-MIMO corresponds to the case where the number of active users is much smaller than the number of BS antennas, which is currently the mainstream definition of LS-MIMO. The type-II LS-MIMO corresponds to the case where the number of active users is comparable to the number of BS antennas. Finally, we discuss the applicability of existing MIMO detection algorithms in LS-MIMO systems, and review some of the recent advances in LS-MIMO detection.

description: The ground states of the frustrated pyrochlore oxide Tb$_{2+x}$Ti$_{2-x}$O$_{7+y}$, sensitively depending on the small off-stoichiometry parameter $x$, have been studied by specific heat measurements using well characterized samples. Single crystal Tb$_{2+x}$Ti$_{2-x}$O$_{7+y}$ boules grown by the standard floating zone technique are shown to exhibit concentration ($x$) gradient. This off-stoichiometry parameter is determined by precisely measuring the lattice constant of small samples cut from a crystal boule. Specific heat shows that the phase boundary of the electric quadrupolar state has a dome structure in the $x$-$T$ phase diagram with the highest $T_{\text{c}} \simeq 0.5$ K at about $x = 0.01$. This phase diagram suggests that the putative U(1) quantum spin-liquid state of Tb$_{2+x}$Ti$_{2-x}$O$_{7+y}$ exists in the range $x

description: In recent years a number of poorly studied chemical elements, such as phosphorus, sulphur, and strontium, have received special attention as important tracers of the Galactic chemical evolution. By exploiting the capabilities of the infrared echelle spectrograph GIANO mounted at the Telescopio Nazionale Galileo, we acquired high resolution spectra of four Galactic dwarf stars spanning the metallicity range between about one-third and twice the solar value. We performed a detailed feasibility study about the effectiveness of the P, S, and Sr line diagnostics in the Y band between 1.03 and 1.10 microm. Accurate chemical abundances have been derived using one-dimensional model atmospheres computed in local thermodynamic equilibrium (LTE). We computed the line formation assuming LTE for P, while we performed non-LTE analysis to derive S and Sr abundances. We were able to derive phosphorus abundance for three stars and an upper limit for one star, while we obtained the abundance of sulphur and strontium for all of the stars. We find [P/Fe] and [S/Fe] abundance ratios consistent with solar-scaled or slightly depleted values, while the [Sr/Fe] abundance ratios are more scattered (by +/-0.2 dex) around the solar-scaled value. This is fully consistent with previous studies using both optical and infrared spectroscopy. We verified that high-resolution, Y-band spectroscopy as provided by GIANO is a powerful tool to study the chemical evolution of P, S, and Sr in dwarf stars.

description: Inclusive production of a quarkonium $η_{c,b}$ in hadron collisions at low transverse momentum can be used to extract various Transverse-Momentum-Dependent(TMD) gluon distributions of hadrons, provided the TMD factorization for the process holds. The factorization involving unpolarized TMD gluon distributions of unpolarized hadrons has been examined with on-shell gluons at one-loop level. In this work we study the factorization at one-loop level with diagram approach in the most general case, where all TMD gluon distributions at leading twist are involved. We find that the factorization holds and the perturbative effects are represented by one perturbative coefficient. Since the initial gluons from hadrons are off-shell in general, there exists the so-called super-leading region found recently. We find that the contributions from this region can come from individual diagrams at one-loop level, but they are cancelled in the sum. Our factorized result for the differential cross-section is explicitly gauge-invariant.

description: The purpose of this study is to evaluate the content of transportation library websites. A  content analysis will be conducted to see what kind of information and which services are  available on these library websites. The study will investigate what services are available  to the public, discuss which services might be reserved for employees and staff of the  transportation libraries, and if the features made accessible depend on the type of  transportation library. Many studies have been conducted on public and academic library  websites. This study hopes to address the lack of information about special library  websites by gathering more information on a specific type of library that serves a specific  information need. The information gathered would hopefully aid transportation libraries  and other special libraries in better serving their clientele by providing more information  about what similar organizations are achieving.

description: Background: Allergic Rhinitis (AR) is defined as inflammation of the inside lining of the nose that occurs when a person inhales something he or she is allergic to, such as animal dander or pollen. Symptoms of AR include sneezing, stuffy nose, runny nose, post nasal drip, and itchy nose. This review identifies and assess studies done with homoeopathic intervention for the management of Allergic Rhinitis. Objective: The aim of this paper was to review the available studies on homeopathic intervention in treatment of allergic rhinitis (AR) and to develop strategy for future research through this review. Materials and Methods: A systematic literature online search was conducted, following International/National search databases for all clinical studies published in the period from 2000 to 2022. This search was aimed to target the entire available literature of randomized trials or controlled trials, observational studies case studies/reports on allergic rhinitis treated in homoeopathy. Relevant research was categorized by study type and appraised according to study design with their clinical outcomes. Results: 38 articles related to Homoeopathy in Allergic Rhinitis were identified. Out of these 17 studies (10 observational studies, 07 RCT’s) were included in this review. Case series, case records, dissertations and review articles were excluded from this review. Conclusion: Studies identified in this review showed that Homoeopathy is effective in the management and prevention of acute episodes of allergic rhinitis also more pragmatic studies need to be planned in the future. Keywords: Allergic rhinitis, Homoeopathy, Systematic review, Randomized controlled trials, Observational studies, Individualization.

Providing Services in an Academic Library: A Comparison of Web-based and Paper Forms
Creators: name: Turner, John D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2000
Subjects: Adoption--user
Use studies--Internet
Accessibility
Circulation procedures--Library services

description: A survey of users of the storage request (closed stacks) service at the University of North Carolina at Chapel Hill provided data for an examination of the differences between Internet users and in-library users of the service. Library services are being offered via the World Wide Web more frequently as the Internet becomes more popular. Libraries are faced with the challenge of marketing Internet services so that patrons accept and use these new services as more traditional services are discontinued. Users were surveyed about their opinions and habits concerning the storage request service. The study found that while user sex did not indicate which method was used, age and access to the library were indicators of service method used. Additionally, promotion of service and user training were determined to be the most effective means of increasing Internet service use. Further study of specific strategies to increase adoption of Internet services is recommended.
Quality enhancement with simultaneous suppression in excess noise of longer-lived states in non-uniformly pumped optical microcavities

description: We study the formation of longer lived states via internal coupling near a special avoided resonance crossing between the interacting states in an open optical system. Away from PT symmetry limit, we discuss the unconventional cavity resonance states created by a spatially varying gain/loss profile. Near certain avoided-resonant crossings (ARC), the parity symmetries of the chosen coupled states dictate the destructive interference resulting high Q, while avoided crossing in the imaginary part of the poles embraces the longer lived state. Now, via S-matrix formalism, we have numerically demonstrated that with suitably chosen system openness and coupling strengths, the excess noise generation among the interacting non-orthogonal states (calculated as Petermann factor K) can be suppressed close to the ideal value 1 with simultaneous order of magnitude enhancement in Q-factor of the longer lived state.

description: In the scientific community, producing high-quality and maintainable code is crucial for accelerating research progress and facilitating collaboration. Clean code enhances readability, making scientific software more easy to understand and reuse by peers and can therefore play a key role in producing FAIR research software. By following clean code principles such as modularization and code organization, code becomes more accessible and reusable, enabling scientists to build upon existing work and share their code with others. Furthermore, clean code enhances maintainability, making it easier to update and modify code to adapt to changing research requirements. By embracing clean code, scientists can create software that is in line with the FAIR principles, fostering reproducibility, collaboration, and the advancement of scientific knowledge. The workshop will begin by providing an overview of the significance of clean code in scientific research, with a particular focus on the advantages it offers in terms of code quality, productivity, and collaboration. Participants will learn how clean code principles align with the unique challenges faced by scientists, such as changing requirements and the need for reproducibility. Throughout the workshop, participants will learn about the core concepts of clean code, covering topics such as naming conventions, code organization, and effective commenting. Practical exercises and examples will reinforce these principles, allowing participants to experience firsthand the impact of clean code on readability and maintainability. The workshop will emphasize the importance of refactoring techniques, teaching participants how to improve existing code without altering its functionality. Participants will explore code smells and anti-patterns commonly encountered in scientific codebases, and learn appropriate refactoring strategies to address them. Through hands-on exercises, participants will gain experience in extracting methods, reducing code duplication, and simplifying complex code. By the end of this workshop, participants will have understand the core principles of clean code and learned essential techniques for improving code quality. They will also have acquired basic skills to create high-quality code that is easy to maintain. Join us for this workshop and unlock the potential of clean code principles. The only way to go fast is to go clean!

description: This study describes a content analysis of virtual reference transcripts taken from the Charlotte Mecklenburg County Public Library virtual reference service. The analysis was performed in order to determine whether and how information literacy instruction is performed in the virtual reference setting. A codebook of instances of instruction was used to identify occurrences of information literacy instruction in the transcripts. Ninety-one chat sessions out of 104 demonstrated instances of information literacy instruction. The majority of this instruction involved the finding and retrieval of information. Little instruction dealt with the use of information once retrieved. Most instruction in this setting seems to happen implicitly, as the librarian performs a search or uses a source. The study indicates that, while instruction is occurring in the virtual setting, many more opportunities to offer instruction exist and should be explored.

Covariant and infrared-free graviton two-point function in de Sitter spacetime

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper, the two-point function of linearized gravitons on de Sitter (dS) space is presented. Technically, respecting the dS ambient space notation, the field equation is given by the coordinate-independent Casimir operators of the de Sitter group. Analogous to the quantization of the electromagnetic field in Minkowski space, the field equation admits gauge solutions. The notation allows us to exhibit the formalism of Gupta-Bleuler triplets for the present field in exactly the same manner as it occurs for the electromagnetic field. In this regard, centering on the spin-two part (the traceless part, ${\cal{K}}^t$), the field solution is written as a product of a generalized polarization tensor and a minimally coupled massless scalar field. Then, admitting a de Sitter-invariant vacuum through the so-called "Krein space quantization", the de Sitter fully covariant two-point function is calculated. This function is interestingly free of pathological large distance behavior (infrared divergence). Moreover, the spin-zero part (the pure-trace part; ${\cal{K}}^{pt}$) of the field is discussed in this paper. It is shown that the implications of the dS group unitary irreducible representations restrict the gauge-fixing parameter to the optimal value, which remarkably results in the pure-trace part be written in terms of a conformally coupled massless scalar field.

description: The Animal Meta-omics landscape database (AnimalMetaOmics, https://yanglab.hzau.edu.cn/animalmetaomics#/) is a comprehensive and freely available resource that includes metagenomic, metatranscriptomic, and metaproteomic data from various non-human animal species and provides abundant information on animal microbiomes, including cluster analysis of microbial cognate genes, functional gene annotations, active microbiota composition, gene expression abundance, and microbial protein identification. In this work, 55,898 microbial genomes were annotated from 581 animal species, including 42,924 bacterial genomes, 12,336 virus genomes, 496 archaea genomes and 142 fungi genomes. Moreover, 321 metatranscriptomic datasets were analyzed from 31 animal species and 326 metaproteomic datasets from four animal species, as well as the pan-genomic dynamics and compositional characteristics of 679 bacterial species and 13 archaea species from animal hosts. Researchers can efficiently access and acquire the information of cross-host microbiota through a user-friendly interface, such as species, genomes, activity levels, expressed protein sequences and functions, and pan-genome composition. These valuable resources provide an important reference for better exploring the classification, functional diversity, biological process diversity, and functional genes of animal microbiota.

Time-dependent Multi-group Multidimensional Relativistic Radiative Transfer Code Based On Spherical Harmonic Discrete Ordinate Method

description: We develop a time-dependent multi-group multidimensional relativistic radiative transfer code, which is required to numerically investigate radiation from relativistic fluids involved in, e.g., gamma-ray bursts and active galactic nuclei. The code is based on the spherical harmonic discrete ordinate method (SHDOM) that evaluates a source function including anisotropic scattering in spherical harmonics and implicitly solves the static radiative transfer equation with a ray tracing in discrete ordinates. We implement treatments of time dependence, multi-frequency bins, Lorentz transformation, and elastic Thomson and inelastic Compton scattering to the publicly available SHDOM code. Our code adopts a mixed frame approach; the source function is evaluated in the comoving frame whereas the radiative transfer equation is solved in the laboratory frame. This implementation is validated with various test problems and comparisons with results of a relativistic Monte Carlo code. These validations confirm that the code correctly calculates intensity and its evolution in the computational domain. The code enables us to obtain an Eddington tensor that relates first and third moments of intensity (energy density and radiation pressure) and is frequently used as a closure relation in radiation hydrodynamics calculations.
