description: This paper presents a case study of the development, launch, and assessment of a mobile application incorporating iBeacon technology at the Charlotte Mecklenburg Library. The iBeacon protocol, along with other "beacon" technologies, has enjoyed success within the retail sector as a platform for proximity marketing, and is drawing interest from libraries as a means of providing digital enhancements to visitor experiences within physical library spaces. The application launched at the Charlotte Mecklenburg Library was assessed positively by library users in comparison to an earlier mobile application that duplicated features of the Library's website, although users expressed dissatisfaction with the push-messaging features present within the application. A set of best practices for incorporating beacons and other location-specific technologies in mobile applications is included for use by technologists and administrators in libraries and other cultural heritage institutions.

description: Business process improvement (BPI) is an important task in times of quickly changing customer requirements and evolving technologies. A variety of BPI approaches were developed in recent years, however, the proper codification of results created in BPI projects has not been properly investigated yet. In this respect, the paper at hand examines the impact of tool-based codification approaches on problem-solving in BPI. Moreover, the effect of the design either as a spreadsheet-based or a conceptual model-based tool on user satisfaction is analyzed. For that purpose, we revert to two tools we developed, which both offer the identical functionality but diverge in the techniques of codifying results: spreadsheet templates on the one side and conceptual models on the other side. In our study, the form of codification tremendously affected the perceived user satisfaction whereas the results received for problem-solving did not show a clear preference. Regarding the former issue, the beneficial role of conceptual models for codifying results with the help of software tools could be demonstrated.

description: Diese Präsentation war Teil des Thementischs "Austausch zur Umsetzung des KDSF – Standard für Forschungsinformationen in Deutschland und der OpenAIRE Guidelines in einem DSpace-CRIS-System" auf dem DSpace Praxistreffen 2023, eine Kooperation der Kommission für Forschungsinformationen in Deutschland (KFiD) und The Library Code GmbH. Abstract des Thementischs: Wie definiert man ein Entitäten- und Metadatenmodell für ein Forschungsinformationssystem mit DSpace-CRIS? Ein wichtiger Ausgangspunkt ist die Berücksichtigung von etablierten Standards, wie zum Beispiel den KDSF-Standard für Forschungsinformationen in Deutschland (kurz für Kerndatensatz Forschung) und den OpenAIRE Guidelines für CRIS-Manager. The Library Code und die Geschäftsstelle der Kommission für Forschungsinformationen (KFiD) laden daher zu einem Austausch ein. Seit Juli 2021 ist die KFiD für die Pflege und Weiterentwicklung des KDSF-Standards verantwortlich. Dieser Thementisch dient auch der Vernetzung von KDSF-Anwender:innen mit der KFiD, um so den Standard und seine Unterstützungsangebote zielgruppengerecht weiterentwickeln zu können.
 Der KDSF definiert – ähnlich wie die OpenAIRE Guidelines – nicht, welche Objekte und Attribute auf der Basisdatenebene vorhanden sein müssen, um die aggregierten Informationen abzubilden. Nach einer kompakten Einführung in den KDSF-Standard und die Aufgaben sowie Ziele der KFiD werden Teile einer durch The Library Code entwickelten konzeptionellen Umsetzung eines Metadatenschemas für DSpace-CRIS zur Diskussion gestellt, welches sowohl Elemente des KDSF-Standards als auch der OpenAIRE Guideline für CRIS Manager integriert. Das vollständige Konzept von The Library Code ist vorab einsehbar unter: https://doi.org/10.5281/zenodo.7712658
Analysis of the ${\frac{1}{2}}^{\pm}$ pentaquark states in the diquark-diquark-antiquark model with QCD sum rules

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this article, we construct both the axialvector-diquark-axialvector-diquark-antiquark type and axialvector-diquark-scalar-diquark-antiquark type interpolating currents, then calculate the contributions of the vacuum condensates up to dimension-10 in the operator product expansion, and study the masses and pole residues of the $J^P={\frac{1}{2}}^\pm$ hidden-charm pentaquark states with the QCD sum rules in a systematic way. In calculations, we use the formula $μ=\sqrt{M^2_{P}-(2{\mathbb{M}}_c)^2}$ to determine the energy scales of the QCD spectral densities. We take into account the $SU(3)$ breaking effects of the light quarks, and obtain the masses of the hidden charm pentaquark states with the strangeness $S=0,\,-1,\,-2,\,-3$, which can be confronted with the experimental data in the future.

description: A diverse, representative workforce is both beneficial and legally mandated for U.S. federal agencies. While previous research documents overall diversity within public agencies, like the USDA Forest Service, little is known about career outcomes and trajectories within these agencies. In this work, we look at individual-level career metrics which reveal patterns in employee retention, advancement, and termination. Using employment data for over 25,000 USDA Forest Service employees, we found that race/ethnicity, gender, and the interaction of these variables significantly related to each career metric. For instance, BIPOC female employees entered at a higher grade but advanced more slowly and spent fewer years with the agency. BIPOC male employees started at lower grades and were more likely to be terminated than any other group. These results suggest that career performance within the Forest Service varies substantially as a function of race and gender. Additional research is needed to uncover why these unequal outcomes occur.

description: We provide a concise overview on transverse momentum dependent (TMD) parton distribution functions, their application to topical issues in high-energy physics phenomenology, and their theoretical connections with QCD resummation, evolution and factorization theorems. We illustrate the use of TMDs via examples of multi-scale problems in hadronic collisions. These include transverse momentum q_T spectra of Higgs and vector bosons for low q_T, and azimuthal correlations in the production of multiple jets associated with heavy bosons at large jet masses. We discuss computational tools for TMDs, and present an application of a new tool, TMDlib, to parton density fits and parameterizations.

description: The work in this task used the linear policy analysis model1 2 and value chain analysis and worked together with stakeholders to understand current policy landscapes, policy relevant challenges and gaps and formulate a set of future concepts for policy interventions that can overcome challenges and facilitate the delivery of sustainable biomass (from industrial crops) to biobased sectors.
 The deliverable is grouped in six sections:
 a) the description of the methodological approaches followed during the study
 b) an overview of the policy related areas that impact on industrial crops, marginal (or with unfavourable conditions) land, conversion and end use markets and perform gap analysis at EU and MS level (with validation at least to the participating ones and the others based on the European databases)
 c) the rationale for future policy interventions
 d) a set of future policy intervention concepts tailored to meet the challenges that occur within the individual value chain stages of industrial crop cultivation in marginal land and their conversion to biobased products
 e) A policy likelihood assessment through a set of key performance indicators that are relevant to the Common Agricultural Policy and the Sustainable Development Goals, and
 f) A separate Annex with policy briefs for each EU Member State and the UK. A quick scan during the policy review at national level, in the countries with Good Practice cases (see Deliverables 7.1 to 7.3) did not identify and special policy for the use of marginal land for industrial crops and their integration in the respective Smart Specialization Strategies. The individual funding source used in the Good Practice cases is described in Deliverable 7.1.

description: The Individuals with Disabilities Act recognizes the importance of helping parents of
children with special needs access information which will assist them to better understand
the nature of their children's disabilities, communicate effectively with service providers,
and learn about resources available to assist their children. In accordance with this Act,
the Tammy Lynn Center for Developmental Disabilities (TLCDD) made a decision in
1999 to convert its library into a special resource center to meet the information needs of
this important population. The purpose of this Master’s project was twofold: first, to
learn from first hand experience how to write a successful grant proposal; and second, to
help TLCDD secure the funds needed to set up its parent resource center. This paper
documents the steps taken and resources used to write the grant proposal. Additionally, it
includes two versions of the final proposal, which were written as a result of the project.

description: Platooning is a way to significantly reduce fuel consumption of trucks. Vehicles that drive at close inter-vehicle distance assisted by automatic controllers experience substantially lower air-drag. In this paper, we deal with the problem of coordinating the formation and the breakup of platoons in a fuel-optimal way. We formulate an optimization problem which accounts for routing, speed-dependent fuel consumption, and platooning decisions. An algorithm to obtain an approximate solution to the problem is presented. It first determines the shortest path for each truck. Then, possible platoon configurations are identified. For a certain platoon configuration the optimal speed profile is the solution to a convex program. The algorithm is illustrated by a realistic example.

 Description: —Cells cylindrical in girdle view, attached through small linking spines. Valve face disc-shaped, flat or slightly sunken, forming a right angle with valve mantle. Striae uniseriate, radiate, leaving a small hyaline area at or near the valve center. External valve face rather rough, occasionally with small spinules between the areolae, internal surface smooth. Poroid areolae round or slightly elliptical. Central area with a ring of numerous (up to 14) carinoportulae. Small rimoportulae with more or less developed internal and external openings, alternating or within the ring of carinoportulae. Valve mantle striae parallel to pervalvar axis composed of small areolae. Lower part of mantle, or collum, unornamented, internally thickened. Cingulum comprising several open copulae. Each girdle band with a hyaline zone on both edges and irregularly arranged round areolae. A relatively large ligula fitting on a slit or anti-ligula of adjacent copula.
 The presence of carinoportulae in the new genus justifies its inclusion within the Order Orthoseirales. Guarreraea can be distinguished from Orthoseira by the presence of small carinoportulae, rimoportulae and the absence of caverns and internal valves.
 Etymology: —named in honor of Dr. Sebastián A. Guarrera, a pioneer in phycological studies in Argentina and South America.

description: We compute the form factors for the $B \to Kl^+l^-$ semileptonic decay process in lattice QCD using gauge-field ensembles with 2+1 flavors of sea quark, generated by the MILC Collaboration. The ensembles span lattice spacings from 0.12 to 0.045 fm and have multiple sea-quark masses to help control the chiral extrapolation. The asqtad improved staggered action is used for the light valence and sea quarks, and the clover action with the Fermilab interpretation is used for the heavy $b$ quark. We present results for the form factors $f_+(q^2)$, $f_0(q^2)$, and $f_T(q^2)$, where $q^2$ is the momentum transfer, together with a comprehensive examination of systematic errors. Lattice QCD determines the form factors for a limited range of $q^2$, and we use the model-independent $z$ expansion to cover the whole kinematically allowed range. We present our final form-factor results as coefficients of the $z$ expansion and the correlations between them, where the errors on the coefficients include statistical and all systematic uncertainties. We use this complete description of the form factors to test QCD predictions of the form factors at high and low $q^2$. We also compare a Standard-Model calculation of the branching ratio for $B \to Kl^+l^-$ with experimental data.

description: This study examines the effect of participants’ distributional preferences on donations of money and time using a field experiment with marine resource users in Indonesia. Individuals participate in a real effort task to earn money and are faced with a donation decision under different treatments – monetary donation, time donation, monetary match, and time match. In the distributional preferences elicitation we classify individuals’ preferences as benevolent, egalitarian, own-money-maximizing, and spiteful. We find that the different distributional preference types are a significant indicator of participants’ donation behavior. The people showing spiteful preferences and those that focus only on maximizing their own payoff are less likely to donate any amount compared to those that make egalitarian choices. Furthermore, we find strong evidence that individuals that choose payoff structures characterized as “benevolent” donate a significantly higher amount compared to the egalitarian types. We analyze the results econometrically in two-stages to better understand the determining factors for whether an individual donates and those factors that determine how much one donates. Practical implications involve the segmentation of the target audience, not by the type of charity but by the mechanism which motivates their donation behavior.

description: This paper looks at current and legacy cataloging practices for collections of rare books with archival elements at Duke University and the University of North Carolina at Chapel Hill. It considers three types of “archival” rare book collections: 1) the personal libraries of writers; 2) personal (research) collections; and 3) large collections of related materials. In considering eight representative collections from two institutions, it answers the following question: How do past and current description practices for “archival” rarebook collections in two ARL libraries in North Carolina compare to the way recent scholarship has proposed these types of collections be described? This paper develops a clear picture of how these types of rare book collections are made visible at these two institutions.

We compute the Hilbert series of the face ring $k[Δ_s (\mathcal{G}_{n,r}^1)]$ for the spanning simplicial complex $Δ_s (\mathcal{G}_{n,r}^1)$. Also, we characterize associated primes of the facet ideal $I_{\mathcal{F}} (Δ_s (\mathcal{G}_{n,r}^1))$. Furthermore, we prove that the face ring $k[Δ_s(\mathcal{G}_{n,r}^{1})]$ is Cohen-Macaulay.

description: Layered and two-dimensional (2D) materials such as graphene, boron nitride, transition metal dichalcogenides(TMDCs), and black phosphorus (BP) have intriguing fundamental physical properties and bear promise of numerous important applications in electronics and optics. Of them, BP is a novel 2D material that has been theoretically predicted to acquire plasmonic behavior for frequencies below ~0.4 eV when highly doped. The electronic properties of BP are unique due to an anisotropic structure, which could strongly influence collective electronic excitations. Advantages of BP as a material for nanoelectronics and nanooptics are due to the fact that, in contrast to metals, the free carrier density in it can be dynamically controlled by electrostatic gating, which has been demonstrated by its use in field-effect transistors. Despite all the interest that BP attracts, near-field and plasmonic properties of BP have not yet been investigated experimentally. Here we report the first observation of nanoscopic near-field properties of BP. We have discovered near field patterns of outside bright fringes and high surface polarizability of nanofilm BP consistent with its surface-metallic, plasmonic behavior at mid-infrared (mid-IR) frequencies. This behavior is highly frequency-dispersive, disappearing above frequency, ω =1070 cm-1, which allowed us to estimate the plasma frequency and carrier density. We have also observed similar behavior in other 2D semiconductors such as TMDCs but not in 2D insulators such as boron nitride. This new phenomenon is attributed to surface charging of the semiconductor nanofilms. This discovery opens up a new field of research and potential applications in nanoplasmonics and optoelectronics.

description: Over the past few decades, reference work has altered as a result of advances in information technology. The purpose of this study is to investigate how questions posed at the Internet Public Library (IPL) virtual reference desk changed over time in difficulty, a concept challenging to define and to measure. Evaluation of reference work has taken a great variety of forms, but no consistent measure examining reference question difficulty has dominated. Few studies have examined reference question difficulty, and those looking at difficulty over time are even rarer. A modified content analysis was used to analyze questions posed to the IPL from 1996 to 2008. An intercoder agreement measure was completed to test reliability. No significant change was found in difficulty of IPL questions over time but satisfactory intercoder reliability was found for the difficulty rating approach. This study supports use of difficulty rating of questions and suggests future research.

description: We obtain an optimal exponential square integrability theorem for the Bergman projection of a function bounded by 1 in modulus. This is interpreted as the statement that the asymptotic tail variance of such a function is at most 1. The asymptotic tail variance defines a seminorm on the Bloch space. We apply the main result to quasiconformal Teichmüller theory, and obtain an estimate of the integral means spectrum of k-quasiconformal mappings that are conformal in the exterior disk: $B(k,t)\le\frac14k^2|t|^2(1+7k)^2$.

description: Optical tweezers have attracted significant attention for microrheological applications, due to the possibility of investigating viscoelastic properties in vivo which are strongly related to the health status and development of biological specimens. In order to use optical tweezers as a microrheological tool, an exact force calibration in the complex system under investigation is required. One of the most promising techniques for optical tweezers calibration in a viscoelastic medium is the so-called active–passive calibration, which allows determining both the trap stiffness and microrheological properties of the medium with the least a-priori knowledge in comparison to the other methods. In this manuscript, we develop an optimization of the active–passive calibration technique performed with a sample stage driving, whose implementation is more straightforward with respect to standard laser driving where two different laser beams are required. We performed microrheological measurements over a broad frequency range in a few seconds implementing an accurate multi-frequency driving of the sample stage. The optical tweezers-based microrheometer was first validated by measuring water, and then exemplarily applied to more viscous medium and subsequently to a viscoelastic solution of methylcellulose in water. The described method paves the way to microrheological precision metrology in biological samples with high temporal- and spatial-resolution allowing for investigation of even short time-scale phenomena.

description: This study examines how users of the immersive virtual environment World of Warcraft  look for information to meet in-world information needs and particularly whether the  ability of users to see and interact with other in-world users has impacted their  information-seeking habits. Sixteen participants were interviewed about what  information they sought, what sources they used, and why.  While participants' purposeful information seeking was fairly similar to that found in  other studies of everyday life or online information seeking, World of Warcraft allowed  participants to incidentally acquire information when other players noticed that a  participant seemed to lack some information and volunteered it. Furthermore, although  in online text-based communities, a community member must choose to share  information for participants to acquire it, in World of Warcraft, participants can  sometimes gain observing other players even if those players did not consciously intend  to provide information.

description: This paper is devoted to the study of the evolution of positively curved metrics on the Wallach spaces $SU(3)/T_{\max}$, $Sp(3)/Sp(1)\times Sp(1)\times Sp(1)$, and $F_4/Spin(8)$. We prove that for all Wallach spaces, the normalized Ricci flow evolves all generic invariant Riemannian metrics with positive sectional curvature into metrics with mixed sectional curvature. Moreover, we prove that for the spaces $Sp(3)/Sp(1)\times Sp(1)\times Sp(1)$ and $F_4/Spin(8)$, the normalized Ricci flow evolves all generic invariant Riemannian metrics with positive Ricci curvature into metrics with mixed Ricci curvature. We also get similar results for some more general homogeneous spaces.

description: Iran is the country of different climates and rich genepool of different medicinal herbs. Both climate variation and available genetic resources, make possible the introduction and improvement of new plant varieties into agriculture. Artemisia dracunculus has been cultivated in different parts of Iran since unknown time. Satureja rechingeri is a wild endemic species growing in desert area of south west of Iran with annual rainfall of less than 250mm while, Solidago virgaurea and Equisetum arvence are native to north and northwest of Iran with more than 700 mm annual rainfall. Several experimets were conducted to introduce new varieties of these plants for economic and high quality plant material production in agricultural systems. Here some of the results are presented.
The role of fear genes in stress and social behavior
Creators: name: Fuentes Hernandez, Ileana
Publisher: name: No Publisher Supplied
Year: 2022

description: The role of genes, regulating fear, in behaviors critical for survival remains unclear and requires further studies at the molecular, cellular and neural circuitry levels. Towards this end, this thesis is focused on how the anatomic neural circuits expressing the gastrin-releasing peptide (GRP) regulate two types of behaviors, those that are related to individual’s threat and those that are related to the survival of the species. Individual’s threat is studied using fear memory extinction in Aim 1. Behaviors related to the species’ survival are studied using maternal behaviors in Aims 2 and 3. The main conclusion from this work is that the molecular mechanisms and neural circuits regulating fear memory are also involved in behaviors critical for the survival of the species.

description: The spin-momentum locked nature of the robust surface states of three dimensional topological insulators (3D TI) make them promising candidates for spintronics applications. Surface potentials which respect time reversal symmetry can exist at the surface between a 3D TI and the trivial vacuum. These potentials can distort the spin texture of the surface states while retaining their gapless nature. In this work, the effect of all such surface potentials on the spin textures is studied. Since, a tunnel magnetoresistance signal carries the information of the spin texture, it is proposed that spin-polarized tunneling of electrons to a 3D TI surface can be used to uniquely identify the surface potentials and quantitatively characterize them.

description: Dimensionality reduction in the bag-of-words vector space document representation  model has been widely studied for the purposes of improving accuracy and reducing  computational load of document retrieval tasks. These techniques, however, have not  been studied to the same degree with regard to document clustering tasks. This study  evaluates the effectiveness of two popular dimensionality reduction techniques for  clustering, and their effect on discovering accurate and understandable topical groupings  of documents. The two techniques studied are Latent Semantic Analysis and  Independent Component Analysis, each of which have been shown to be effective in the  past for retrieval purposes.

description: We monitored the recent FUor 2MASS J06593158-0405277 (V960 Mon) since November 2009 at various observatories and multiple wavelengths. After the outburst by nearly 2.9 mag in $r$ around September 2014 the brightness gently fades until April 2015 by nearly 1 mag in $U$ and 0.5 mag in $z$. Thereafter the brightness at $λ>5000 Å$ was constant until June 2015 while the shortest wavelengths ($U, B$) indicate a new rise, similar to that seen for the FUor V2493 Cyg (HBC722). Our near-infrared (NIR) monitoring between December 2014 and April 2015 shows a smaller outburst amplitude ($\sim$2 mag) and a smaller (0.2 $-$ 0.3 mag) post-outburst brightness decline. Optical and NIR color-magnitude diagrams indicate that the brightness decline is caused by growing extinction. The post-outburst light curves are modulated by an oscillating color-neutral pattern with a period of about 17 days and an amplitude declining from $\sim$0.08 mag in October 2014 to $\sim$0.04 mag in May 2015. The properties of the oscillating pattern lead us to suggest the presence of a close binary with eccentric orbit.

Needs assessment

description: This study describes interviews of adolescents between the ages of thirteen and nineteen attending teen programs at public libraries in southeastern North Carolina and of the teen librarians running those programs. The interviews were conducted to determine the different assessment criteria used by teens and teen librarians when assessing teen programs in public libraries.  Subjects at six different teen programs at four public libraries were used to explore the similarities and differences in assessment of teen programs. In these North Carolina public libraries, teens and teen librarians use both similar and dissimilar criteria to measure program success.

description: The supertree construction problem is about combining several phylogenetic trees with possibly conflicting information into a single tree that has all the leaves of the source trees as its leaves and the relationships between the leaves are as consistent with the source trees as possible. This leads to an optimization problem that is computationally challenging and typically heuristic methods, such as matrix representation with parsimony (MRP), are used. In this paper we consider the use of answer set programming to solve the supertree construction problem in terms of two alternative encodings. The first is based on an existing encoding of trees using substructures known as quartets, while the other novel encoding captures the relationships present in trees through direct projections. We use these encodings to compute a genus-level supertree for the family of cats (Felidae). Furthermore, we compare our results to recent supertrees obtained by the MRP method.
