description: The interaction effects of different fertilisation regimes and weather variability on crop yield is a challenge that requires long-term investigation. Therefore, yield data for spring barley (SB) in an agricultural long-term field experiment, established in 1963 in Müncheberg, northeast Germany, were analysed to reveal the effects of 21 fertiliser regimes and different weather conditions on SB yields. SB yields were significantly affected by fertilisation regimes (11%), annual weather conditions (55%) and their interaction effect (8%). Mineral N fertilization decreased overall yield variability across seasons as compared to no fertilization and organic fertilization regimes showed higher yield variability. A suitable combined application of mineral nitrogen and organic fertiliser was found to be an effective way to produce higher SB yields than the application of either mineral nitrogen or organic fertiliser alone. A Bayesian linear regression model showed total precipitation during the growing season (April–July) positively affected on SB yields when high mineral N was supplied. At the early growth stage, a precipitation rate (March) and temperature (April or sowing day) negatively affected on SB yield.

description: This research describes the results of a study of homeschool administrators (i.e., parents) in Alamance County and Orange County, North Carolina and their use of the Mebane Public Library. A survey was conducted to determine if the programming and library collections available to homeschooling parents meet their curriculum needs. As this alternative form of education has gained popularity, many public libraries have seen an increase in the number of homeschoolers that use their facilities. Among the suggestions made by librarians experienced in this area are programming opportunities for homeschoolers as well as a well-rounded collection consisting of a variety of formats. Homeschoolers using the Mebane Public Library feel that enough programming is offered to meet their curriculum needs despite the fact that their attendance of these programs is very low. Suggestions for future programming were made. In general, homeschooling parents find that the Mebane Public Library's collection meets their needs, with additional materials available elsewhere in the systems as well as through Interlibrary Loan.

description: We investigate how hybridization (single-quasiparticle scattering) between two superconducting bands induces odd-frequency superconductivity in a multiband superconductor. An explicit derivation of the odd-frequency pairing correlation and its full frequency dependence is given. We find that the density of states is modified, from the sum of the two BCS spectra, at higher energies by additional hybridization gaps with strong coherence peaks when odd-frequency pairing is present.

Feasibility of Diagrammatic Monte-Carlo based on weak-coupling expansion in asymptotically free theories: case study of $O(N)$ sigma-model in the large-$N$ limit

description: We discuss the feasibility of applying Diagrammatic Monte-Carlo algorithms to the weak-coupling expansions of asymptotically free quantum field theories, taking the large-$N$ limit of the $O(N)$ sigma-model as the simplest example where exact results are available. We use stereographic mapping from the sphere to the real plane to set up the perturbation theory, which results in a small bare mass term proportional to the coupling $λ$. Counting the powers of coupling associated with higher-order interaction vertices, we arrive at the double-series representation for the dynamically generated mass gap in powers of both $λ$ and $\log(λ)$, which converges quite quickly to the exact non-perturbative answer. We also demonstrate that it is feasible to obtain the coefficients of these double series by a Monte-Carlo sampling in the space of Feynman diagrams. In particular, the sign problem of such sampling becomes milder at small $λ$, that is, close to the continuum limit.

Information Assessment

description: Prior literatures have shown that American public libraries have made an effort to provide trustworthy health information to their users in diverse ways such as reference services, reader advisement, and acquisition of health materials. In that manner, this paper primarily deals with the assessment of health information provided on North Carolina public libraries websites focusing on teenager users. Results have shown that only 31.3% of public library websites in NC provide health resources focusing on adolescent users. In terms of resources' specified topics, resources cover a variety of health issues including not only general health but also sensitive teen issues such as sexual health, drugs and alcohols, STDs, self-abuse, and birth control. When it comes to the evaluation of the health information provided on NC public libraries websites, 39 teen health resources out of total forty-five (86.67%) were determined either 'strongly reliable' or 'reliable' online sources. Despite a few limitations, this author believes that findings are appropriate for basing future research of assessing teen health information in public library settings.

description: The importance of data hiding in the field of Information Technology is a widely accepted. The challenge is to be able to pass information in a manner that the very existence of the message is unknown in order to repel attention of the potential attacker. Steganography is a technique that has been widely used to achieve this objective. However Steganography is often found to be lacking when it comes to hiding bulk data. Attempting to hide data in a video overcomes this problem because of the large sized cover object (video) as compared to an image in the case of steganography. This paper attempts to propose a scheme using which data can be hidden in a video. We focus on the Triangularization method and make use of the Least Significant Bit (LSB) technique in hiding messages in a video.

description: The application of remote-sensing technology is relatively new and limited in energy cane (Saccharum spp.) production in Louisiana. This study was conducted at LSU AgCenter Sugar Research Station in St. Gabriel, Louisiana, from 2013 to 2015, to evaluate the relationship of spectral reflectance readings with stalk, nitrogen (N) uptake and fiber yield of energy cane harvested at different dates and to identify vegetation indices (VIs) that can be used for stalk and fiber yield prediction. Treatments included variety (Ho 02-113, US 72-114), N rate (0, 56, 112 and 224 kg N ha−1) and harvest dates arranged in split–split plot in a randomized complete block design with four replications. Canopy reflectance readings were collected from nine spots per plot using Jaz® hyperspectral spectrometer from 3 to 16 weeks after N application. Stalk yield for different harvest dates was estimated based on 15-stalk sampling or plot harvesting. The Pearson correlation analysis showed a strong dependence between VIs (computed from reflectance readings at 670 and 705 nm) and stalk yield, N uptake and fiber yield across cane age, demonstrating the potential use of optical remote sensing in energy cane stalk and fiber yield prediction.

description: In this work we study the $ρB^*\bar{B}^*$ three-body system solving the Faddeev equations in the fixed center approximation. We assume the $B^*\bar{B}^*$ system forming a cluster, and in terms of the two-body $ρB^*$ unitarized scattering amplitudes in the local Hidden Gauge approach we find a new $I(J^{PC})=1(3^{--})$ state. The mass of the new state corresponds to a two particle invariant mass of the $ρB^\ast$ system close to the resonant energy of the $B^\ast_2(5747)$, indicating that the role of this $J=2$ resonance is important in the dynamical generation of the new state.

Usability testing Evaluation methods

description: Multiple studies comparing remote usability testing to traditional laboratory testing indicate that both methods yield similar results. Now that confidence in the value of remote usability studies has been established, the human factors community would benefit from a comparison of remote testing methodologies in order to identify their advantages and disadvantages. The study compares instant messaging (IM) and telephone communication when used for synchronous remote usability evaluations. No significant differences were found for task completion status, task completion time, or questionnaire results. Significant differences were found between total word counts per participant. Average word counts for telephone usability tests were nearly five times that of IM usability tests. Overall, the telephone condition yielded more favorable results and richer feedback than the IM testing condition. Results from this study suggest that telephone communication is more effective than IM when used for synchronous remote usability evaluations.

description: The CRESST-II experiment uses cryogenic detectors to search for nuclear recoil events induced by the elastic scattering of dark matter particles in CaWO$_4$ crystals. Given the low energy threshold of our detectors in combination with light target nuclei, low mass dark matter particles can be probed with high sensitivity. In this letter we present the results from data of a single detector module corresponding to 52 kg live days. A blind analysis is carried out. With an energy threshold for nuclear recoils of 307 eV we substantially enhance the sensitivity for light dark matter. Thereby, we extend the reach of direct dark matter experiments to the sub-region and demonstrate that the energy threshold is the key parameter in the search for low mass dark matter particles.

description: Optimization of manganese-substituted iron oxide nanoferrites having the composition MnxFe1-xFe2O4 (x = 0-1) has been achieved by the chemical co-precipitation method. The crystallite size and phase purity were analyzed from X-ray diffraction. With increases in Mn2+ concentration, the crystallite size varies from 5.78 to 9.94 nm. Transmission electron microscopy (TEM) analysis depicted particle sizes ranging from 10 +/- 0.2 to 13 +/- 0.2 nm with increasing Mn2+ substitution. The magnetization (Ms) value varies significantly with increasing Mn2+ substitution. The variation in the magnetic properties may be attributed to the substitution of Fe2+ ions by Mn2+ ions inducing a change in the superexchange interaction between the A and B sublattices. The self-heating characteristics of MnxFe1-xFe2O4 (x = 0-1) nanoparticles (NPs) in an AC magnetic field are evaluated by specific absorption rate (SAR) and intrinsic loss power, both of which are presented with varying NP composition, NP concentration, and field amplitudes. Mn0.75Fe0.25Fe2O4 exhibited superior induction heating properties in terms of a SAR of 153.76 W/g. This superior value of SAR with an optimized Mn2+ content is presented in correlation with the cation distribution of Mn2+ in the A or B position in the Fe3O4 structure and enhancement in magnetic saturation. These optimized Mn0.75Fe0.25Fe2O4 NPs can be used as a promising candidate for hyperthermia applications.

description: This paper presents the findings of a case study in evaluation and preservation of a title held in a collection of historic Latin American newspapers at the University of North Carolina at Chapel Hill. The Academic Affairs Library holds in storage the complete run from 1911-1945 of the Venezuela newspaper El Universal, which has been continually published in Caracas since 1909. Although the newspapers are embrittled and their bound folio volumes damaged, they nevertheless represent a considerable information resource. Not only does this paper outline the issues related to evaluating, preserving, and providing access to this particular title, it also provides a framework to guide the process that is applicable to other collections of historic newspapers in academic research libraries.

description: Epitaxial growth of graphene on transition metal substrates is an important route for obtaining large scale graphene. However, the interaction between graphene and the substrate often leads to multiple orientations, distorted graphene band structure, large doping and strong electron-phonon coupling. Here we report the growth of monolayer graphene with high crystalline quality on Pt(111) substrate by using a very low concentration of an internal carbon source with high annealing temperature. The controlled growth leads to electronically decoupled graphene: it is nearly charge neutral and has extremely weak electron-phonon coupling (coupling strength $λ$ $\approx$ 0.056) as revealed by angle-resolved photoemission spectroscopic measurements. The thermodynamics and kinetics of the carbon diffusion process is investigated by DFT calculation. Such graphene with negligible graphene-substrate interaction provides an important platform for fundamental research as well as device applications when combined with a nondestructive sample transfer technique.

description: Cultural institutions are using social media, like Twitter, to promote digitized primary source collections to teachers. With so many resources dedicated to social media outreach, it is necessary to examine the effectiveness of cultural institutions' outreach to teachers. This study examines the Twitter messages produced by three U.S. cultural institutions and identifies the relationship between message characteristics and the perceived value of the messages by K-12 teachers. A content analysis of tweets selected from the Twitter timelines of the Smithsonian Institution, National Archives and Records Administration, and the National Endowment of Humanities education outreach departments identified the types of content produced by these cultural institutions. Categories that emerged from the content analysis were used to develop a survey to explore the value of the tweets to teachers. This study provides insight into the use of Twitter messages for outreach to teachers and offers recommendations for improving Twitter outreach to teachers.

Being tranceported vs. Just Being: Ludic Reading and Zen Meditation

description: This paper examines ludic reading, in which the reader "disappears" into a book, and Zen meditation, in which practitioners see the world as it is, giving rise to an opening of the heart. Interestingly, these two activities are sometimes interpreted as being at odds with each other: ludic reading involves a psychic journey to another time and place, while Zen meditation concerns itself most emphatically with the here and now. While from a certain angle this is irrefutably true, this paper takes the alternate tack of considering the congruencies inherent in absorbed reading and meditation. Looking more closely, both ludic reading and Zen meditation involve the dissolution of a strong sense of selfhood and are methods of experiencing the balm of nonduality. This conclusion is arrived at with the help of scholarly works, books on Buddhist practice, and most importantly with the first-hand reports of practitioners of deep reading and Zen meditation.

description: Biopolymers serve as one-dimensional tracks on which motor proteins move to perform their biological roles. Motor protein phenomena have inspired theoretical models of one-dimensional transport, crowding, and jamming. Experiments studying the motion of Xklp1 motors on reconstituted antiparallel microtubule overlaps demonstrated that motors recruited to the overlap walk toward the plus end of individual microtubules and frequently switch between filaments. We study a model of this system that couples the totally asymmetric simple exclusion process (TASEP) for motor motion with switches between antiparallel filaments and binding kinetics. We determine steady-state motor density profiles for fixed-length overlaps using exact and approximate solutions of the continuum differential equations and compare to kinetic Monte Carlo simulations. Overlap motor density profiles and motor trajectories resemble experimental measurements. The phase diagram of the model is similar to the single-filament case for low switching rate, while for high switching rate we find a new low density-high density-low density-high density phase. The overlap center region, far from the overlap ends, has a constant motor density as one would naively expect. However, rather than following a simple binding equilibrium, the center motor density depends on total overlap length, motor speed, and motor switching rate. The size of the crowded boundary layer near the overlap ends is also dependent on the overlap length and switching rate in addition to the motor speed and bulk concentration. The antiparallel microtubule overlap geometry may offer a previously unrecognized mechanism for biological regulation of protein concentration and consequent activity.

description: It has been shown that the heating, ventilation, and air conditioning (HVAC) systems of commercial buildings can offer ancillary services to power systems without loss of comfort. In this paper, we propose a new control framework for reliable scheduling and provision of frequency reserves by aggregations of commercial buildings. The framework incorporates energy-constrained frequency signals, which are adopted by several transmission system operators for loads and storage devices. We use a hierarchical approach with three levels: (i) reserve capacities are allocated among buildings (e.g., on a daily basis) using techniques from robust optimization, (ii) a robust model predictive controller optimizes the HVAC system consumption typically every 30 minutes, and (iii) a feedback controller adjusts the consumption to provide reserves in real time. We demonstrate how the framework can be used to estimate the reserve capacities in simulations with typical Swiss office buildings and different reserve product characteristics. Our results show that an aggregation of approximately 100 buildings suffices to meet the 5 MW minimum bid size of the Swiss reserve market.

description: This paper has presented the case study of the corporate library at BCBSNC, from August 1997 to July 1999.  The purpose of the study was: 1. To describe the transition of a specific library from "nice" to "necessary" through an outline of the steps followed and general strategic considerations that accompanied them, as well as the specific strategies applied in the case study. 2. To indicate how this process and accompanying strategic considerations can be done in such a way as to both (1) create specific successes for the library and (2) move the library to a position of greater value in the company.  The study can be used as a roadmap for other librarians who need to create change and desire to do so in such a way as to move the library to a position of increased value to the corporation.

description: Even when cooled through its transition temperature in the presence of an external magnetic field, a superconductor can expel nearly all external magnetic flux. This Letter presents an experimental study to identify the parameters that most strongly influence flux trapping in high purity niobium during cooldown. This is critical to the operation of superconducting radiofrequency cavities, in which trapped flux degrades the quality factor and therefore cryogenic efficiency. Flux expulsion was measured on a large survey of 1.3 GHz cavities prepared in various ways. It is shown that both spatial thermal gradient and high temperature treatment are critical to expelling external magnetic fields, while surface treatment has minimal effect. For the first time, it is shown that a cavity can be converted from poor expulsion behavior to strong expulsion behavior after furnace treatment, resulting in a substantial improvement in quality factor. Future plans are described to build on this result in order to optimize treatment for future cavities.

Public libraries--Case studies

description: This paper examines the workforce development programs implemented at the Cumberland County Public Library. The case study focuses on the specific initiatives and evaluation methods implemented by the library for workforce development programs. Analysis indicates that the efforts and initiative of library personnel is a key factor in successful implementation and evaluation of workforce development programs in addition to in-depth research and innovative approaches to data collection. Funding plays an important but supplementary role in supporting initiatives. Finally, job fairs are key workforce development initiatives which illustrate the findings in the paper.

description: We propose an algorithm which allows to derive the generalized Alexander polynomial invariants of knots and links with the help of the q,p-numbers, appearing in bosonic two-parameter quantum algebra. These polynomials turn into HOMFLY ones by applying special parametrization. The Jones polynomials can be also obtained by using this algorithm.

Aussie/Not Aussie: Widening the Postcolonial Lens
Creators: name: Tonge, Ann Ruth
Publisher: name: Cardiff Metropolitan University
Year: 2023
Subjects: Creative writing (incl. scriptwriting)

description: This practice-based thesis consists of a novel and a self-reflective critical paper examining memory, transcultural identity and storytelling in contemporary Australian literature. The novel, Dear Gods & Little Fishes, is a combination of memoir, acquired memory, knowledge, imaginings and stories. Set in the 1960’s, it is the story of one family’s physical and psychological journey through unfamiliar land and culture and developing senses of self in connection to the landscape and disconnection from familiarity. An important theme of the novel is the intersection of different margins, relationships between disparate types of (not) belonging and power, against the socio-political background of ‘white Australia’. The critical element explores the history of postcolonial (settler) literary theory and whether the inherent themes and considerations are adequate or appropriate for analysing Australian contemporary writing, given Australia’s unique history and landscapes. This contextualises and informs the personal reflections that affected the writing of Dear Gods & Little Fishes. In writing about my own lived (and writerly) experience, I found new elements of experience and understanding. The two elements together are therefore my statement of poetics, reflecting my own identity and voice. Chapter One focuses on the historical background and landscape of Australian literature and examines its inclusion in the realm of postcolonial literary theory. Chapter Two considers portrayal of identity and self-identity, with a particular focus on the transcultural, and examines the ‘right’ to tell stories. Chapter 3 explores ideas of spirituality and connection to place as portrayed in the creative element of the thesis and in the work of other Australian writers. Finally, Chapter 4 draws together the threads of the discussion and concludes that the reading and writing of Australian literature is best done in full knowledge of the impact of colonisation but not limited by focus through an ageing Postcolonial lens.

Appraisal of archival materials
Archives surveys

description: Archives, libraries, and museums focused on performing arts have collected musical instruments alongside traditional archival materials in order to connect patrons with the tools musicians and composers utilize to shape cultural legacies.  This mixed-methods study illuminates how cultural heritage institutions apply basic archival functions (appraisal, arrangement, description, access, and preservation) to musical instruments. Representatives from four such institutions were interviewed: Three archives (The Institute of Jazz Studies, the Rock & Roll Hall of Fame Library & Archives, and the Louis Armstrong Archives) and one museum (The Metropolitan Museum of Art). Simultaneously, a survey was distributed to archivists, with respondents detailing their experiences and philosophies related to archiving musical instruments. Issues discussed by those interviewed and surveyed included the importance of a well-defined collecting policy, an access policy that makes holdings available to users while ensuring that the artifacts accessed are subjected to minimal potential damage, and approaches to instrument preservation.

description: Digital libraries are seeking innovative ways to share their resources and enhance user  experience. To this end, numerous openly available technologies can be exploited. For  this project, NER technology was applied to a subset of the Documenting the American  South (DocSouth) digital collections. Personal and location names were hand-annotated  to achieve a gold standard, and GATE, a text engineering tool, was run under two  conditions: a defaults baseline and a test run that included gazetteers built from  DocSouth's Colonial and State Records collection. Overall, GATE performance is  promising, and numerous strategies for improvement are discussed. Next, derived  location annotations were georeferenced and stored in a geodatabase through automated  processes, and a prototype for a web-based map search was developed using the Google  Maps API. This project showcases innovations with automated NER coupled with GIS  technologies, and strongly supports further investment in applying these techniques  across DocSouth and other digital libraries.

description: We investigate magnetic properties of strongly interacting four component spin-3/2 ultracold fermionic atoms in the Mott insulator limit with one particle per site in an optical lattice with honeycomb symmetry. In this limit, atomic tunneling is virtual, and only the atomic spins can exchange. We find a competition between symmetry breaking and liquid like disordered phases. Particularly interesting are valence bond states with bond centered magnetizations, situated between the ferromagnetic and conventional valence bond phases. In the framework of a mean-field theory, we calculate the phase diagram and identify an experimentally relevant parameter region where a homogeneous SU(4) symmetric Affleck-Kennedy-Lieb-Tasaki-like valence bond state is present.

description: This study examines the interaction between narrative and collaborative worldbuilding and premade, extensive rulesets in tabletop role-playing games. This study specifically looks at the game Dungeons and Dragons 5th edition and included interviews with six participants on how they balanced the collaborative narrative environment and expressing creativity while working within a system with extensive rules and guidelines for how the game functions.While participants did acknowledge that the rules were important, the rules themselves function more as paratexts, or guidelines. They functioned to create a consistent, understandable environment within which to create a narrative, but participants recognized that if these guidelines hamper the enjoyment or flow of the game and story they could be changed or ignored for the players’ benefit. Furthermore, players were more likely to break the rules or allow others to do so if there was a creative and interesting narrative purpose, as it was important to allow all players to have agency and input in the narrative and to ensure that the story itself was enjoyable for all involved.
Chemical Tracers of Pre-Brown Dwarf Cores Formed Through Turbulent Fragmentation

description: A gas-grain time dependent chemical code, UCL\_CHEM, has been used to investigate the possibility of using chemical tracers to differentiate between the possible formation mechanisms of brown dwarfs. In this work, we model the formation of a pre-brown dwarf core through turbulent fragmentation by following the depth-dependent chemistry in a molecular cloud through the step change in density associated with an isothermal shock and the subsequent freefall collapse once a bound core is produced. Trends in the fractional abundance of molecules commonly observed in star forming cores are then explored to find a diagnostic for identifying brown dwarf mass cores formed through turbulence. We find that the cores produced by our models would be bright in CO and NH$_3$ but not in HCO$^+$. This differentiates them from models using purely freefall collapse as such models produce cores that would have detectable transitions from all three molecules.
