description: The experimental realization of lattices with Chern bands in ultracold-atom and photonic systems has motivated the study of time-dependent phenomena, such as spatial propagation, in lattices with nontrivial topology. We study the dynamics of gaussian wavepackets on the Haldane honeycomb Chern-band lattice model, in the presence of a harmonic trap. We focus on the transverse response to a force, which is due partly to the Berry curvature and partly to the transverse component of the energy band curvature. We evaluate the accuracy of a semiclassical description, which treats the wavepacket as a point particle in both real and momentum space, in reproducing the motion of a realistic wavepacket with finite extent. We find that, in order to accurately capture the wavepacket dynamics, the extent of the wavepacket in momentum space needs to be taken into account. The dynamics is sensitive to the interplay of band dispersion and Berry curvature over the finite region of momentum (reciprocal) space where the wavepacket has support. Moreover, if the wavepacket is prepared with a finite initial momentum, the semiclassical analysis reproduces its motion as long as it has a large overlap with the eigenstates of a single band. The semiclassical description generally improves with increasing real-space size of the wavepacket, as long as the external conditions (e.g., external force) remain uniform throughout the spatial extent of the wavepacket.

description: Geolocation services in mobile devices provide the opportunity for software developers to write apps that personalize information based on the user's location. By utilizing GPS, cellular tower location, and information about nearby wireless networks, mobile apps can determine the device's location and use this information for a variety of purposes. Web-based services such as Google Places provide an easy way to find information about establishments, including their locations, user reviews, price range, and more, and by searching with an app like Google Maps for iPhone, users can find which establishments are near their current location. While there are many iPhone apps intended for finding nearby restaurants and other establishments, there are not many that focus strongly on the open hours of the restaurants. "What's Open?" is an iPhone app designed to help people find nearby restaurants, based on their open hours, and to view detailed information about them.

description: We report the discovery of an excess of main sequence turn-off stars in the direction of the constellations of Eridanus and Phoenix from the first year data of the Dark Energy Survey (DES). The Eridanus-Phoenix (EriPhe) overdensity is centered around l~285 deg and b~-60 deg and spans at least 30 deg in longitude and 10 deg in latitude. The Poisson significance of the detection is at least 9 sigma. The stellar population in the overdense region is similar in brightness and color to that of the nearby globular cluster NGC 1261, indicating that the heliocentric distance of EriPhe is about d~16 kpc. The extent of EriPhe in projection is therefore at least ~4 kpc by ~3 kpc. On the sky, this overdensity is located between NGC 1261 and a new stellar stream discovered by DES at a similar heliocentric distance, the so-called Phoenix Stream. Given their similar distance and proximity to each other, it is possible that these three structures may be kinematically associated. Alternatively, the EriPhe overdensity is morphologically similar to the Virgo overdensity and the Hercules-Aquila cloud, which also lie at a similar Galactocentric distance. These three overdensities lie along a polar plane separated by ~120 deg and may share a common origin. Spectroscopic follow-up observations of the stars in EriPhe are required to fully understand the nature of this overdensity.

description: Alternative boll weevil/cotton insect management programs were evaluated for their effects on net market benefits and for their distributive impacts on producers and consumers. The Optimum Pest Management with No incentives and Boll Weevil Eradication (OPM-NI-BWE) program produced the highest net market program costs. Consumer benefits from lower prices greatly exceeded the loss of producer incomes and public costs. The Optimum Pest Management with No Incentive (OPM-NI) program produced the highest rate of return on Federal investment. A B/C ratio of 44:1 was obtained, compared with 17:1 for OPM-NI-BWE.

Subjects: Bookstores--Evaluation
Bookstores--Relations with libraries

description: The bookstore used to be a place where people would go to buy books.  They would find what they wanted, buy the book, and go home.  With the advent of the superstore ten years ago, the situation has changed and grown a great deal.  Today, one can walk into a bookstore and see customers using their laptops in the café, taking notes from a book, attending a children's story hour, or reading a stack of magazines.  Bookstores have changed from a place of commerce to a destination, becoming in some ways, competition for the library.  Using content analysis, this study examines the literature of the last ten years for the trends in the bookstores and separates them into five major categories - physical space, programming, electronic services, store types, and services.  Then the data was analyzed for patterns and themes, and implications for libraries were drawn from the results.

Evidence-based medicine

description: This paper explores what, if any, identifiable differences exist in the way health care  professionals and library professionals perceive the potential contributions of librarians to  the practice of evidence-based medicine. The question this paper seeks to answer is: Are  the actions performed by health science librarians in supporting the practice of evidence-based  medicine presented differently in the literature targeted toward healthcare  professionals than in the literature targeted toward health science librarians? Forty-five  journal articles were analyzed to determine what actions librarians were depicted as  performing in order to support evidence-based medicine. Nine of the articles were from  healthcare provider-oriented journals, and 36 of the articles were from librarian-oriented  journals. The results of this study suggest that librarians' roles in supporting the practice  of evidence-based medicine are represented as having more variety and depth in the  librarian-oriented literature when compared to the healthcare provider-oriented literature.

description: The agronomical potential and the phytochemical variability of 18 genotypes of the Paraguayan plant Stevia rebaudiana have been investigated in Switzerland in order identify the best genotype for local cultivation. Over a two years period, yields in dry leaves ranged from 10 to 170 g m-2, with a percentage of leaves ranging from 53 to 75 %. HPLC analyses showed a notable variability in phytochemical composition, with stevioside content ranging from 0.3 to 7.9 % w/w and rebaudioside A from 0.3 to 6.5 % w/w. Cultivation of S. rebaudiana in Switzerland is feasible. With a density of 10 plants per m2, the potential yields of dry matter are approximately 1-2 t ha-1. The most productive genotypes (Pharmasaat, Hem Zaden, Stepa and Mediplant 3 and 11) will be submitted to the industry for organoleptic evaluation.

 Type:— NEW CALEDONIA. Plateau de Dogny, September 1909, Le Rat 825 (holotype: P-00537661!, isotypes: K-000739770!, P-00537662!, P-00537663!)
 Polyosma leratii var. puberula Guillaumin (1939: 278);  syn. nov.  Lectotype (designated here): − NEW CALEDONIA. s. loc., 24 september 1876, Lécard bois n°31 (P-00537660!). Syntypes: − forêts situées au sud de Canala, 1000 m, 20 November 1869, Balansa 1783 (P-02582511!, P-02582510!, P-02582512!); Lécard 93 (P-00639324!); possible syntypes: − Lécard s.n. (P-00639325!, P-00639326!)
 Guillaumin (1920) cited a single collection in his description of P. leratii: Le Rat 825. There are three sheets at P. One bears the handwritten “type” with Guillaumin’s signature, and can be considered as the holotype.
 In his description of the variety puberula, Guillaumin (1939) cited two collections: Balansa 1783 and Lécard 93, bois n°31. Among several collections of Lécard at P, a single sheet bears the additive information “bois N°31” with the handwritten ” Polyosma leratii var. puberula ”, “type” and Guillaumin’s signature. It is therefore chosen as a lectotype. The variety name was not indicated in any of the sheets Balansa 1783 at P or the single sheet labelled “Lécard n° 93”. The variety puberula only differs from the typical variety by the pubescence of the inflorescence and this does not seem to correlate with ecology or geography. It is not maintained here as distinct.

description: This study examines collection development policies and practices at American undergraduate libraries, with particular emphasis on how these have been affected by recent trends in higher education and academic librarianship. Librarians from ten undergraduate libraries across the country were interviewed about collecting practices at their institutions as well as the role of their library and its collection in the university library system. The interview questions selected for this study focus on the ways in which collection development practices at undergraduate libraries relate to - and are impacted by - three areas of current interest to academic libraries: (1) changes in university curricula, (2) the expansion of information literacy programs, and (3) the proliferation of new information technologies and networked environments.

description: Searching for appropriate web services on the internet is becoming more and more laborious, because it depends on human processing and evaluating of the available web services in UDDI repositories. Furthermore, if the requester language is different form available WSDL files then it would be more complicated. If this process could be done automatically, this will save effort and time. In order to make this factual, ontologies and semantic web technologies were used, ontology is needed to facilitate interoperability between agents and web services, to make them interoperate semantically, and to make processing of the data could be achieved automatically. In paper we propose an ontology server expected to help searching and selecting appropriate web service even if it is available in UDDI in different language.

Subjects: subject: soft lithography
subject: microfluid

description: The ability to trap single cells inside a microfluidic chip and subsequent imaging is normally paired with the use of a precise and expensive external pressure source to control the liquid flow. Here we present a self-filling particle trapping chip, which can be used without additional equipment. Different designs of hydrodynamic cell traps were evaluated using cell sized beads and Jurkat T cells. Also, how different plasma treatment conditions of the PDMS surface combined with accelerated aging influence the trapping ability of the chips was investigated. The cell-trapping and self-filling function of the chip could be validated but optimisations of the design are recommended to increase the efficiency.

description: The copper silver selenide has two phases: the low-temperature semimetal phase (α-CuAgSe) and high-temperature phonon-glass superionic phase (\b{eta}-CuAgSe). In this work, the electric transport and thermoelectric properties of the two phases are investigated. It is revealed that the \b{eta}-CuAgSe is a p-type semiconductor and exhibits low thermal conductivity while the α-CuAgSe shows metallic conduction with dominant n-type carriers and low electrical resistivity. The thermoelectric figure of merit zT of the polycrystalline \b{eta}-CuAgSe at 623 K is ~0.95, suggesting that superionic CuAgSe can be a promising thermoelectric candidate in the intermediate temperature range.

description: The proposed study describes an investigation into the extent of censorship by categorization of materials. The study will examine the placement of ten historically controversial young adult works in ten public library systems in North Carolina. This investigation was conducted to measure what percentage of libraries classified pre-designated young adult materials as adult material. Failure to place the more than 25% of the preselected young adult materials into the section classified as young adult within their library resulted in the library being designated as engaging in advertent or inadvertent censorship by placement.
Obtaining pure steady states in nonequilibrium quantum systems with strong dissipative couplings

description: Dissipative preparation of a pure steady state usually involves a commutative action of a coherent and a dissipative dynamics on the target state. Namely, the target pure state is an eigenstate of both the coherent and dissipative parts of the dynamics. We show that working in the Zeno regime, i.e. for infinitely large dissipative coupling, one can generate a pure state by a non commutative action, in the above sense, of the coherent and dissipative dynamics. A corresponding Zeno regime pureness criterion is derived. We illustrate the approach, looking at both its theoretical and applicative aspects, in the example case of an open $XXZ$ spin-$1/2$ chain, driven out of equilibrium by boundary reservoirs targeting different spin orientations. Using our criterion, we find two families of pure nonequilibrium steady states, in the Zeno regime, and calculate the dissipative strengths effectively needed to generate steady states which are almost indistinguishable from the target pure states.

Positivity Bias in Judging In-group Members’ Emotional Expressions
Creators: name: Lazerus, Talya
Publisher: name: Open Science Framework
Year: 2022

description: We investigate how group membership impacts valence judgments of in- and out-group members’ emotional expressions. In Experiment 1, participants, randomized into two novel, competitive groups, rated the valence of in- and out-group members’ facial expressions (fear, happy, neutral) using a circumplex affect grid. Across all emotions, participants judged in-group members’ expressions as more positive than out-group members’ expressions. In Experiment 2, participants categorized fear and happy expressions as being either positive or negative using a mouse-tracking paradigm. Participants exhibited the most direct trajectories toward the positive label for in-group happy expressions and an initial attraction toward ‘positive’ for in-group fear expressions, with out-group emotion trajectories falling in between. Experiment 3 replicated Experiment 2 and demonstrated that the effect could not be accounted for by targets’ gaze direction. Overall, people judged in-group faces as more positive, regardless of emotion, both in deliberate and implicit judgments.

description: Damask rose (Rosa damascena Mill.) is the most important species in the production of rose water, perfumes and essential oils (EOs), perfumery and pharmaceutical industry applications. In order to exploit the most of this precious Iranian flower, research was conducted on two damask rose genotypes (Fars 1 and Fars 2) in six development stages in terms of EOs content and composition analysis. Results showed that all development stages of damask rose genotypes had significant differences in the EOs content. The highest EOs content was obtained from "Fars 2" genotype. It was found that the oil obtained from the dried petals of Fars 2 genotype contained a higher percentage of citronellol (C), geraniol (G) and phenylethyl alcohol (PEA) as well as a suitable ratio of C/G with the value of 2.464 as compared with Fars 1 genotype (5.546). In the last stages of flower bud development in both genotypes, the sum of the main hydrocarbons increased while citronellol content decreased, therefore essential oil quality dramatically declined. EO quantity was lower in the middle stages of flower bud development (stages 3 and 4) as compared to the final stages (stage 5 and 6), but its quality was superior in the former stages. Generally, it seems that "Fars 2" damask rose, as a promising genotype, can be used for EO production.

description: To date O2 has definitely been detected in only two sources, namely rho Oph A and Orion, reflecting the extremely low abundance of O2 in the interstellar medium. One of the sources in the HOP program is the +50 km/s Cloud in the Sgr A Complex in the centre of the Milky Way. The Herschel HIFI is used to search for the 487 and 774 GHz emission lines of O2. No O2 emission is detected towards the Sgr A +50 km/s Cloud, but a number of strong emission lines of methanol (CH3OH) and absorption lines of chloronium (H2Cl+) are observed. A 3 sigma upper limit for the fractional abundance ratio of (O2)/(H2) in the Sgr A +50 km/s Cloud is found to be X(O2) less than 5 x 10(-8). However, since we can find no other realistic molecular candidate than O2 itself, we very tentatively suggest that two weak absorption lines at 487.261 and 487.302 GHz may be caused by the 487 GHz line of O2 in two foreground spiral arm clouds. By considering that the absorption may only be apparent, the estimated upper limit to the O2 abundance of less than (10-20) x 10(-6) in these foreground clouds is very high. This abundance limit was determined also using Odin non-detection limits. If the absorption is due to a differential Herschel OFF-ON emission, the O2 fractional abundance may be of the order of (5-10) x 10(-6). With the assumption of pure absorption by foreground clouds, the unreasonably high abundance of (1.4-2.8) x 10(-4) was obtained. The rotation temperatures for CH3OH-A and CH3OH-E lines in the +50 km/s Cloud are found to be 64 and 79 K, respectively, and the fractional abundance of CH3OH is approximately 5 x 10(-7).

description: Duplin county, NC has the highest hog-population density of any county in the United States. Liquid manure from industrial-sized hog concentrated animal feeding operations (CAFOs) is stored in open-air lagoons and sprayed onto sprayfields as fertilizer. Hog CAFOs are regulated by the NC Department of Environment and Natural Resources (DENR) based on their ability to have nutrient management plans (NMPs) that have balanced plant available nitrogen (PAN) so that the estimated portion of nitrogen that remains available for crops to use after irrigation is absorbed. Objectives of this research are to quantify the difference in permitted PAN between CAFO point and sprayfield area locations at two sub-watershed scales in Duplin county by conducting a review of all 485 active CAFOs and creating a sprayfield spatial database. Second, a new method incorporating remote sensing data identifies annual PAN for crops on sprayfields and two sub-watershed scales in Duplin county between 2010-2014.

Optimizing Reader Proteins for Use as Detection Reagents
Creators: name: Parker, Madison
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Post translational modifications (PTMs) including trimethyllysine (Kme3) on histone tails serve as epigenetic markers that influence gene expression, and antibodies have been crucial tools for detecting PTMs on histone tails. However, antibody recognition is sensitive to local sequences as well as neighboring PTMs, and antibodies cannot efficiently distinguish among specific methylation states of lysine. Proteins bind PTMs on histone tails, their inherent specificity is a candidate mechanism for detecting PTMs. Here, we took advantage of the selectivity of native reader proteins and created high affinity variants that recognize Kme3 at position 9 on histone 3 (H3K9me3). Previously, single point mutations of the Heterochromatin protein 1 (HP1) from Drosophila melanogaster chromodomain confer 2-fold higher affinity binding on native Kme3 substrates. We hypothesized that combinations of mutations (A25T, K46A, E52D, D62F) would have additive effects on the affinity of HP1 with Kme3. A triple mutant (K46A/E52D/D62F) exhibited increased binding by ~ 20-fold with respect to wild-type. The triple mutant HP1 protein also showed increased selectivity to H3K9me3 than the wild-type protein. This mutant will provide a new tool with higher specificity to trimethyllysine, which will complement current antibody-based approaches for detecting and distinguishing PTMs in standard biochemical assays. Since many diseases are associated with dysregulation of gene expression due to abnormal PTMs, such a tool will have applications for characterizing aberrant patterns of PTMs.

description: We numerically investigate the effect of magnetic and electrical damages at the edge of a perpendicular magnetic random access memory (MRAM) cell on the spin-transfer-torque (STT) efficiency that is defined by the ratio of thermal stability factor to switching current. We find that the switching mode of an edge-damaged cell is different from that of an undamaged cell, which results in a sizable reduction in the switching current. Together with a marginal reduction of the thermal stability factor of an edge-damaged cell, this feature makes the STT efficiency large. Our results suggest that a precise edge control is viable for the optimization of STT-MRAM.

description: The superconducting properties of a recently discovered high $T_{\rm c}$ superconductor, Sr/ammonia-intercalated FeSe, have been measured using pulsed magnetic fields down to $4.\,\rm {K}$ and muon spin spectroscopy down to $1.5\,\rm K$. This compound exhibits intrinsic disorder resulting from random stacking of the FeSe layers along the $c$-axis that is not present in other intercalates of the same family. This arises because the coordination requirements of the intercalated Sr and ammonia moieties imply that the interlayer stacking (along $c$) involves a translation of either ${\bf a}/2$ or ${\bf b}/2$ which locally breaks tetragonal symmetry. The result of this stacking arrangement is that the Fe ions in this compound describe a body-centred tetragonal lattice in contrast to the primitive arrangement of Fe ions described in all other Fe-based superconductors. In pulsed magnetic fields the upper critical field $H_{\text{c2}}$ was found to increase on cooling with an upwards curvature that is commonly seen in type-II superconductors of a multi-band nature. Fitting the data to a two-band model and extrapolation to absolute zero gave a maximum upper critical field ${μ_0H_{\rm c2}(0)}$ of ${33(2)\,\rm T}$. A clear superconducting transition with a diamagnetic shift was also observed in transverse-field muon measurements at ${T_{\text c}\approx36.3(2)\,\rm K}$. These results demonstrate that robust superconductivity in these intercalated FeSe systems does not rely on perfect structural coherence along the $c$-axis.

Explanation through Analogical Reasoning in Aristotle's Natural Science
Creators: name: Smith, Nathan L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Analogy features prominently in Aristotle’s writing; yet, the scholarship rarely treats Aristotle’s scientific use of analogy—or its use in any area—apart from its literary merits. The few works that do discuss analogy in Aristotle’s scientific writings tend to make two simple characterizations. The first, the weaker reading, sees analogy as serving a didactic function only and as carrying no explanatory force. It takes analogy to be something along the lines of an example or illustration, something that supports or embellishes the argument or explanation, while not being integral to Aristotle’s investigation or causal accounts. On this view, Aristotle uses analogy to comfort or instruct the reader rather than as part of his methods of inquiry. The second, which offers a somewhat stronger reading, considers analogy to be a heuristic device towards the generation of genuine causal explanations. On this reading, analogy functions as something that guides Aristotle’s investigation and discovery of an explanation but is not itself part of that explanation and, therefore, does not carry any explanatory force itself. No doubt, both didactic and heuristic uses of analogies are part of Aristotle’s writings and are quite common forms of analogy in his corpus. As I argue in the present essay, however, there is a third, largely overlooked type of analogy at play in Aristotle’s scientific treatises, namely, reasoning by analogy. While didactic analogies illustrate a phenomenon that is explainable in other ways and heuristic analogies can help lead one to an explanation, in analogical reasoning, the analogy itself functions as the explanation. This makes reasoning by analogy a potentially powerful method of scientific investigation.

description: We present quantum Monte Carlo calculations of light nuclei, neutron-$α$ scattering, and neutron matter using local two- and three-nucleon ($3N$) interactions derived from chiral effective field theory up to next-to-next-to-leading order (N$^2$LO). The two undetermined $3N$ low-energy couplings are fit to the $^4$He binding energy and, for the first time, to the spin-orbit splitting in the neutron-$α$ $P$-wave phase shifts. Furthermore, we investigate different choices of local $3N$-operator structures and find that chiral interactions at N$^2$LO are able to simultaneously reproduce the properties of $A=3,4,5$ systems and of neutron matter, in contrast to commonly used phenomenological $3N$ interactions.

description: The driving of charge carriers confined in a quantum well lacking the center of space inversion by an alternating electric field leads to the formation of a direct electric current. We develop a microscopic theory of such a quantum ratchet effect for quantum wells subjected to a static magnetic field. We show that the ratchet current emerges for a linearly polarized alternating electric field as well as a rotating electric field and drastically increases at the cyclotron resonance conditions. For the magnetic field tilted with respect to the quantum well normal, the ratchet current contains an additional resonance at the first subharmonic of the cyclotron resonance.

description: Background: The COVID-19 pandemic has resulted in delays in the treatment of patients with urological malignancies. The management of bladder cancer (BC) in particular poses a significant challenge given the recurrent nature of the disease and the intense follow-up regime required for many cases. The aim of this study was to evaluate potential changes in the presentation and operative management of BC in our hospital following the pandemic. Materials and methods: This is a retrospective cohort study. Potential BC cases were identified through the histopathology database between March 2019 and February 2021. Details were obtained on patient demographics, procedure type such as biopsy, resection or excision, grade and stage of BC. Cases were divided into two groups: period one (pre-COVID between March 2019 and February 2020) and period two (post-COVID between March 2020 and February 2021). Results: A total of 207 procedures for confirmed BC were performed during the study period, 126 in period one and 81 in period two. New cases accounted for 52.4% (n = 66) and 53.1% (n = 43) of cases during periods one and two respectively. There was a higher rate of invasive disease (43.2% vs 26.2%) as well as high grade disease (47.4% vs 35.8%) in period two than in period one. Conclusion: Fewer BC procedures were performed in the COVID period. The higher rate of more advanced stage and grade of disease seen in period two suggests patients are presenting later. This should be considered when allocating resources in the management of non-COVID related diseases. Further studies are needed to assess the long-term impact of COVID-19 on bladder cancer outcome.

Selective Classification of Citrullination and Acetylation on Histone Tails via Organic Receptor Molecules
Creators: name: Ramsay, Christopher
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The goal of this research is to determine whether an indicator displacement assay using organic small-molecule receptors and a fluorescent dye lucigenin (LCG) can correctly classify citrullination and acetylation in the context of histone tail peptides. Difference in fluorescent signal, dictated by the displacement of receptor-bound LCG, will be the benchmark by which the post-translational modifications (PTMs) of interest will be classified. Linear discrimination analysis (LDA) will provide the statistical means to visually separate and classify the fluorescence data for several species into respective categories. The proposed assay schema was shown to be effective in differentiating similarly citrullinated and acetylated peptides at low concentrations (15 μM) and was shown to be sensitive enough for 10 μM in citrullinated H3 tail peptides and 5 μM in acetylated H3 tail peptides.

description: The Modified Fluctuation Dissipation Theorem (MFDT) proposed by G. Verley et al. {\it (EPL 93, 10002, (2011))} for non equilibrium transient states is experimentally studied. We apply MFDT to the transient relaxation dynamics of the director of a liquid crystal after a quench close to the critical point of the Fréedericksz transition (Ftr), which has several properties of a second order phase transition driven by an electric field. Although the standard Fluctuation Dissipation Theorem (FDT) is not satisfied, because the system is strongly out of equilibrium, the MFDT is perfectly verified during the transient in a system which is only partially described by Landau-Ginzburg (LG) equation, to which our observation are compared. The results can be useful in the study of material aging.
