description: In this paper, we consider a nonlinear interaction system between the barotropic mode and the first baroclinic mode of the tropical atmosphere with moisture; that was derived in [Frierson, D.M.W.; Majda, A.J.; Pauluis, O.M.: Dynamics of precipitation fronts in the tropical atmosphere: a novel relaxation limit, Commum. Math. Sci., 2 (2004), 591-626.] We establish the global existence and uniqueness of strong solutions to this system, with initial data in $H^1$, for each fixed convective adjustment relaxation time parameter $\varepsilon>0$. Moreover, if the initial data enjoy slightly more regularity than $H^1$, then the unique strong solution depends continuously on the initial data. Furthermore, by establishing several appropriate $\varepsilon$-independent estimates, we prove that the system converges to a limiting system, as the relaxation time parameter $\varepsilon$ tends to zero, with convergence rate of the order $O(\sqrt\varepsilon)$. Moreover, the limiting system has a unique global strong solution, for any initial data in $H^1$, and such unique strong solution depends continuously on the initial data if the the initial data posses slightly more regularity than $H^1$. Notably, this solves the VISCOUS VERSION of an open problem proposed in the above mentioned paper of Frierson, Majda and Pauluis.

description: The objective of this task was to present a large group of data on the suitability of selected industrial crops to marginal soils, helping to clarify the constraints associated with their cultivation under low-input practices.
 The experimental field trials included the following annual oil [industrial hemp (Cannabis sativa L.), safflower (Carthamus tinctorius L.), crambe (Crambe abyssinica Hochst.), camelina (Camelina sativa L.), Ethiopian mustard (Brassica carinata A. Braun), castor (Ricinus communis L.)] and carbohydrate crops [biomass sorghum (Sorghum bicolor L. Moench)]; perennial, lignocellulosic, herbaceous, such as giant reed (Arundo donax L.), miscanthus (Miscanthus spp.), African fodder cane (Saccharum spontaneum L. spp. aegyptiacum Willd. Hackel), tall wheatgrass (Thinopyrum ponticum (Podp.) and switchgrass (Panicum virgatum L.), and woody crops [Siberian elm (Ulmus pumila L.) and willow (Salix spp.)].
 Low-input agricultural practices were applied to the above industrial crops with the main aim to ascertain their performances in sites affected by biophysical limitations across Europe. European countries were grouped, according to the European climatic stratification proposed by Metzger et al. (2005), in three main agro-ecological zone: Mediterranean, Atlantic and Continental.
 Biophysical limitations are essentially those reported in the JRC study (Rossiter et al., 2014), which alone or in combination leads to negative synergies to crop yield. MAGIC, through this task, will provide hints on how the cultivation of these crops in marginal soils can mitigate indirect land-use change (iLUC) risks, in accordance with the sustainability criteria set in the Directive (EU) 2018/2001 and to meet the European Green Deal towards an EU climate neutral in 2050.

description: In this paper we present a general method for estimating rates of accidental coincidence between a pair of single photon detectors operated within their saturation regimes. By folding the effects of recovery time of both detectors and the detection circuit into an "effective duty cycle" we are able to accomodate complex recovery behaviour at high event rates. As an example, we provide a detailed high-level model for the behaviour of passively quenched avalanche photodiodes, and demonstrate effective background subtraction at rates commonly associated with detector saturation. We show that by post-processing using the updated model, we observe an improvement in polarization correlation visibility from 88.7% to 96.9% in our experimental dataset. This technique will be useful in improving the signal-to-noise ratio in applications which depend on coincidence measurements, especially in situations where rapid changes in flux may cause detector saturation.

description: This paper examines the efforts one health science library puts into outreach and marketing through social media platforms. It focuses specifically on a case study of the University of North Carolina at Chapel Hill Health Science Library. There is a strong correlation between the content of social media posts and the number of patron interactions with said post. Visual content in posts boosts interactions, but creating posts with only links does not. The data gathered from the study will allow for the library to target its postings in the future, which in turn could garner more followers and interactions with patrons.

Recommender systems

description: Building recommender systems is usually divided into two processes: (1) segmenting the  dataset such that elements with similar pattern can be grouped together, and (2)  performing association rules that tell how likely the two elements occur together. For the  first process, between clustering method and LC subject heading classification, which  segmentation method is more appropriate to build the library circulation recommender  systems?  Based on the association rules generated from two different simulated datasets, we  consistently find that using clustering method to segment the dataset yields a higher level  of support and confidence. However, consider that forming distinct clusters is not likely  to happen in reality, together with patron's interest may change swiftly over time. Using  clustering as the segmentation method will finally generate many irrelevant association  rules. As a result, we conclude that using LC classification to segment the data is more  appropriate and secure.

description: We apply the soft wall holographic model from hadron physics to a description of the high-$T_c$ superconductivity. In comparison with the existing bottom-up holographic superconductors, the proposed approach is more phenomenological. On the other hand, it is much simpler and has more freedom for fitting the conductivity properties of the real high-$T_c$ materials. We demonstrate some examples of emerging models and discuss a possible origin of the approach.

Reflections of ‘Active Learning’ and ‘Scaffolding’ in lesson plans for teaching political science at the undergraduate level in Bangladesh: A review.pdf
Creators: name: Mojumder, Mohammad Jahangir Hossain
Publisher: name: figshare
Year: 2023
Subjects: Curriculum and pedagogy theory and development

description: Background: Teaching-learning is gradually shifting from instructor- oriented to learner-centred approach and students are increasingly demanded to be engaged in various learning activities instead of being passive receivers of instructions in and outside the classroom. This strategical development promotes different types of teaching-learning methods. ‘Active learning’ and ‘scaffolding,’ for example, are two such tactics among others under the constructivist theory. This study has included these two methods to reflect on three proposed lesson plans to demonstrate incorporation of activities in-between traditional lectures in line with these theoretical directions. Aim and objectives: This study has intended to understand the ways of incorporation of learner-centred approch method like active learning and scaffolding for teaching Political Science. In addition, efforts have been made for realising improvement in learning outcomes, implications and impediments of the process and to suggest way out. Methodology: Methodologically, the study is a theory oriented and review-based project; and thus, data have been collected from various published and unpublished secondary sources, such as articles, books, reports, blogs, dissertations, and other web-based sources. Results: The results suggest that shifting to student-centred methods, infusing them into lessons plans, and executing them in the classroom activate students to construct knowledge and contribute to better learning. However, varied challenges like teachers’ sceptical attitude and unwillingness, learners’ unfamiliarity, large class size, faulty classroom settings, and unfavourable school culture may impede practice of student-centred approaches and produce unintended results. Likewise, without learners’ insightful knowledge on concepts of syllabi and curriculum, merely introducing activities according to these approaches will not be enough. Therefore, passionate endeavours of all stakeholders and gradual reforms of the education system are necessary.

description: For library professionals, the responsibility to facilitate access to information resources includes developing cataloging, labeling, and shelving practices and adapting them to fit new formats added to the collection. As the graphic novel format grows in popularity in public library collections, academic and professional conversations have emerged around the issues of how to catalog, label, and shelve these works.The Chapel Hill Public Library is interested in supplementing its adult and young adult graphic novel collections and establishing an updated, consistent practice for the cataloging, labeling, and shelf classification of these works. In order to assess the current state of these collections and practices, a list-checking study and a direct collection analysis utilizing shelf lists were conducted. These analyses identified collection gaps, inconsistencies in practice, and major decision points to be addressed in the next stages of the graphic novel project.

description: Health care increasingly requires complicated self-care regimens that demand patients and family caregivers learn about unfamiliar topics and practices to support their recovery. Due to the prevalence of low health literacy, patient education materials must comply with health literacy standards so that all patients understand how to take care of themselves. This content analysis examines the quality and consistency of patient education materials used at a large academic medical center to inform self-care of burns, tracheostomy, and peripherally-inserted central catheters. The Patient Education Material Assessment Tool (PEMAT) was used to evaluate thirteen patient education materials from inpatient, outpatient, and home health settings. PEMAT scores were associated with the presence of visual aids and document source. Consistency of materials was greatest among documents describing self-care for burns. Study methods employed may be used as a foundation for assessment of additional patient education materials.

description: Research reports that the search for health information is the fourth most popular activity being done on the web (Pew Internet & American Life Project, 2004). However, for disabled persons, barriers experienced when interfacing with the Internet may cause healthcare websites to be inaccessible to them. This study explores the level of accessibility of healthcare websites and the relationship between accessibility and usability by determining how compliant state department of health and human services websites are with accessibility and usability guidelines. A content analysis of each state's department of health and human services website was conducted. Results revealed that state department of health and human services websites are not very compliant with accessibility guidelines, are somewhat compliant with usability guidelines, and overall are not very accessible. The findings also indicate that there is a significant moderate relationship between accessibility and usability which suggests that the two concepts are interconnected.

 Denton (1993: 534) inadvertently published Sedum paradisum at species rank as a nomen nudum; here we validate the name with reference to the basionym.
 We treated Sedum paradisum as two geographic subspecies. Between their ranges lies Lassen Peak and a large area affected by its eruptions. Appropriate habitat for Sedum is limited in this area because most rock outcrops were recently exposed and excessively dry. We hypothesize that any Sedum paradisum once present in this area was killed by the eruptions of Lassen Peak in 1914, or in previous volcanic episodes dating back 27,000 years.

description: The study of the Ashkin-Teller model (ATM) of spin-3/2 on a hypercubic lattice is undertaken via Monte Carlo simulation. The phase diagrams are displayed and discussed in the physical parameter space. Rich physical properties are recovered, namely the second order transition and multicritical points. The phase diagrams have been obtained by varying the strength describing the four spin interaction and the single ion potential. This model shows a new high temperature partially ordered phase, called $\langle S\rangle$ and a new Baxter 3/2 ground state which do not exist either in the spin-1/2 ATM or in the spin-1 ATM.

description: The role of paraprofessionals in public libraries is in flux, and is a source of debate among library and information professionals.  The present study offers empirical illumination to this discussion by employing a web-based questionnaire survey inquiring into the relationship between job responsibility and turnover rate for paraprofessional positions.  While this study was exploratory in nature, analysis of the results uncovered evidence for a negative correlation between the turnover rate for a given paraprofessional position and that position's level of resemblance to MLS-requiring positions.  Implications of this finding and limitations of the survey are discussed, and avenues for future research are suggested.

description: Buetti, Cronin, Madison, Wang, & Lleras (in press) recently reported that, contrary to previous theories, the first stage of processing in visual search varies systematically with the number of items in the display and that this variation is modulated by target-distractor similarity. In this study, we aim to investigate whether the order in which candidates are scrutinized during stage-two processing is ranked-order by target-distractor similarity (as most theories assume) or whether the order is in fact random (see Buetti et al., in press). That is to say, do observers scrutinize candidates according to their visual similarity to the target, inspecting the most similar candidates first and the least similar candidates last?

description: We study the problem of distributed adaptive estimation over networks where nodes cooperate to estimate physical parameters that can vary over both space and time domains. We use a set of basis functions to characterize the space-varying nature of the parameters and propose a diffusion least mean-squares (LMS) strategy to recover these parameters from successive time measurements. We analyze the stability and convergence of the proposed algorithm, and derive closed-form expressions to predict its learning behavior and steady-state performance in terms of mean-square error. We find that in the estimation of the space-varying parameters using distributed approaches, the covariance matrix of the regression data at each node becomes rank-deficient. Our analysis reveals that the proposed algorithm can overcome this difficulty to a large extent by benefiting from the network stochastic matrices that are used to combine exchanged information between nodes. We provide computer experiments to illustrate and support the theoretical findings.

description: An analysis of dijet events in PbPb and pp collisions is performed to explore the properties of energy loss by partons traveling in a quark-gluon plasma. Data are collected at a nucleon-nucleon center-of-mass energy of 2.76 TeV at the LHC. The distribution of transverse momentum (pT) surrounding dijet systems is measured by selecting charged particles in different ranges of pT and at different angular cones of pseudorapidity and azimuth. The measurement is performed as a function of centrality of the PbPb collisions, the pT asymmetry of the jets in the dijet pair, and the distance parameter R used in the anti-kt jet clustering algorithm. In events with unbalanced dijets, PbPb collisions show an enhanced multiplicity in the hemisphere of the subleading jet, with the pT imbalance compensated by an excess of low-pT particles at large angles from the jet axes.

Search for vector-like charge 2/3 T quarks in proton-proton collisions at sqrt(s) = 8 TeV

Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search for fermionic top quark partners T of charge 2/3 is presented. The search is carried out in proton-proton collisions corresponding to an integrated luminosity of 19.7 inverse femtobarns collected at a center-of-mass energy of sqrt(s) = 8 TeV with the CMS detector at the LHC. The T quarks are assumed to be produced strongly in pairs and can decay into tH, tZ, and bW. The search is performed in five exclusive channels: a single-lepton channel, a multilepton channel, two all-hadronic channels optimized either for the bW or the tH decay, and one channel in which the Higgs boson decays into two photons. The results are found to be compatible with the standard model expectations in all the investigated final states. A statistical combination of these results is performed and lower limits on the T quark mass are set. Depending on the branching fractions, lower mass limits between 720 and 920 GeV at 95% confidence level are found. These are among the strongest limits on vector-like T quarks obtained to date.

Bibliographic relationships

description: Current library catalogs do not fulfill users' needs for navigating freely from one record to related records. They also fail to meet the second objective of the library catalog either because of the generic defect of current linking devices and omission of virtual copies. The application of hypertext system to the traditional library catalog is suggested for a solution, because this type of OPAC system is able to present links in a more user-friendly way. The new system is named hypercatalog. An expanded USMARC format is suggested for data structure of the hypercatalog. The hypercatalog is expected to be able to offer an appropriate interface to present links for related bibliographic records for both of Web resources and traditional library resources. The end users activate these links after a query using the hit as the starting point merely clicking one of links on the full bibliographic record screen.

Marginal Lands

description: The scope of the Task 4.4 was to gain new insights into industrial crops (camelina, crambe, safflower, castor, switchgrass, miscanthus, tall wheatgrass, willow, poplar and Siberian elm) grown at farm-scale under different pedo-climatic and marginality conditions across Europe. Large demo fields (not replicated) were established in Italy, Spain, France, Greece, Poland, Ukraine and Latvia and carried out under real operational conditions. At least two different industrial crops were tested in each country.
 The results show that marginality conditions can dramatically affect the productivity depending on species and marginality factor; however, some crops seem to have great potentials on marginal land if adequate agricultural practices are properly addressed for the specific marginal conditions.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Cluster analyses are an established method for identifying natural groupings of customers for customer segmentation. However, the unsupervised nature of clustering algorithms and the high-dimensionality of customer data complicate the analysis at all stages. This project presents the results from a cluster analysis of high-dimensional customer data from a subscription-based software company. The analysis tested multiple dimensionality reduction methods, outlier and noise detection methods, and clustering algorithms (including deep neural networks). The results and models from the analysis can be used to inform strategy around customer support and feedback, and can serve as the basis from which additional analyses can be conducted.

description: Maximizing the sustainable supercurrent density, Jc, is crucial to high current applications of superconductivity and, to achieve this, preventing dissipative motion of quantized vortices is key. Irradiation of superconductors with high-energy heavy ions can be used to create nanoscale defects that act as deep pinning potentials for vortices. This approach holds unique promise for high current applications of iron-based superconductors because Jc amplification persists to much higher radiation doses than in cuprate superconductors without significantly altering the superconducting critical temperature. However, for these compounds virtually nothing is known about the atomic scale interplay of the crystal damage from the high-energy ions, the superconducting order parameter, and the vortex pinning processes. Here, we visualize the atomic-scale effects of irradiating FeSexTe1-x with 249 MeV Au ions and find two distinct effects: compact nanometer-sized regions of crystal disruption or 'columnar defects', plus a higher density of single atomic-site 'point' defects probably from secondary scattering. We show directly that the superconducting order is virtually annihilated within the former while suppressed by the latter. Simultaneous atomically-resolved images of the columnar crystal defects, the superconductivity, and the vortex configurations, then reveal how a mixed pinning landscape is created, with the strongest pinning occurring at metallic-core columnar defects and secondary pinning at clusters of pointlike defects, followed by collective pinning at higher fields.

The Ewald-Oseen Extinction Theorem
Creators: name: Mansuripur, Masud
Publisher: name: arXiv
Year: 2015
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: When a beam of light enters a material medium, it sets in motion the resident electrons, whether these electrons are free or bound. The electronic oscillations in turn give rise to electromagnetic radiation which, in the case of linear media, possess the frequency of the exciting beam. Because Maxwell's equations are linear, one expects the total field at any point in space to be the sum of the original (exciting) field and the radiation produced by all the oscillating electrons. However, in practice the original beam appears to be absent within the medium, as though it had been replaced by a different beam, one having a shorter wavelength and propagating in a different direction. The Ewald-Oseen theorem resolves this paradox by showing how the oscillating electrons conspire to produce a field that exactly cancels out the original beam everywhere inside the medium. The net field is indeed the sum of the incident beam and the radiated field of the oscillating electrons, but the latter field completely masks the former. Although the proof of the Ewald-Oseen theorem is fairly straightforward, it involves complicated integrations over dipolar fields in three-dimensional space, making it a brute-force drill in calculus and devoid of physical insight. It is possible, however, to prove the theorem using plane-waves interacting with thin slabs of material, while invoking no physics beyond Fresnel's reflection coefficients. The thin slabs represent sheets of electric dipoles, and the use of Fresnel's coefficients allows one to derive exact expressions for the electromagnetic field radiated by these dipolar sheets. The goal of the present article is to outline a proof of the Ewald-Oseen theorem using arguments that are based primarily on thin-film optics.

description: A flux formulation of Double Field Theory on group manifold is derived and applied to study generalized Scherk-Schwarz compactifications, which give rise to a bosonic subsector of half-maximal, electrically gauged supergravities. In contrast to the flux formulation of original DFT, the covariant fluxes split into a fluctuation and a background part. The latter is connected to a $2D$-dimensional, pseudo Riemannian manifold, which is isomorphic to a Lie group embedded into O($D,D$). All fields and parameters of generalized diffeomorphisms are supported on this manifold, whose metric is spanned by the background vielbein $E_A{}^I \in$ GL($2D$). This vielbein takes the role of the twist in conventional generalized Scherk-Schwarz compactifications. By doing so, it solves the long standing problem of constructing an appropriate twist for each solution of the embedding tensor. Using the geometric structure, absent in original DFT, $E_A{}^I$ is identified with the left invariant Maurer-Cartan form on the group manifold, in the same way as it is done in geometric Scherk-Schwarz reductions. We show in detail how the Maurer-Cartan form for semisimple and solvable Lie groups is constructed starting from the Lie algebra. For all compact embeddings in O($3,3$), we calculate $E_A{}^I$.

description: The adsorption of two different organic molecules cyanidin glucoside (C$_{21}$O$_{11}$H$_{20}$) and TA-St-CA on anatase (101) and (001) nanowires have been investigated using the standard and the range separated hybrid density functional theory calculations. The electronic structures and optical spectra of resulting dye--nanowire combined systems show distinct features for these types of photochromophores. The lowest unoccupied molecular orbital of the natural dye cyanidin glucoside is located below the conduction band of the semiconductor while, in the case of TA-St-CA, it resonates with the states inside the conduction band. The wide-bandgap anatase nanowires can be functionalized for solar cells through electron-hole generation and subsequent charge injection by these dye sensitizers. The intermolecular charge transfer character of Donor-$π$-Acceptor type dye TA-St-CA is substantially modified by its adsorption on TiO$_2$ surfaces. Cyanidin glucoside exhibits relatively stronger anchoring on the nanowires through its hydroxyl groups. The atomic structures of dye--nanowire systems re-optimized with the inclusion of nonlinear solvation effects showed that the binding strengths of both dyes remain moderate even in ionic solutions.

Library shelving

description: Training students to work in academic libraries is important work.  It is also constant, given the nature of student turnover.  Therefore, library managers and trainers should seek efficiencies in training without sacrificing quality. One part of training to examine for efficiencies is LC (Library of Congress) shelving training. This study examines which characteristics the best interactive electronic LC shelving games share per a literature review.  Then it compares the performance of twenty shelvers who trained with a high-quality interactive electronic LC shelving training tool versus the performance of twenty shelvers who trained with an excellent static guide.  The interactive electronic group scored higher on average and experienced fewer low scores on the LC shelving test. More significantly, the interactive group members pinpointed where they made errors, which suggests that library employees trained with interactive shelving tutorials would need less remediation than employees who were trained using static shelving guides.
The collection of alternative press materials by a member of the Association of Research Libraries: a case study

College and university libraries--Collection development

description: This study discusses the collection of materials listed in the Alternative Press Index (API) by a member of the Association of Research Libraries (ARL). The author analyzed the library's collection to determine library holdings and possible subject area biases. The findings were compared to study conducted by Marinko and Gerhard and published in the July 1998 issue of College and Research Libraries. Factors influencing the collection of alternative material were gathered during an interview with four collection development librarians. The following conclusions were reached: 1) A researcher can not confidently claim an accurate assessment of a library's holdings after searching only one source 2) The collection of alternative materials is dependent upon institutional values and the views of individual librarians. 3) Future research examining the collection of alternative publications should be conducted on the local level.
Wave equations on the linear mass Vaidya metric

description: We discuss the near singularity region of the linear mass Vaidya metric. In particular we investi- gate the structure in the numerical solutions for the scattering of scalar and electromagnetic metric perturbations from the singularity. In addition to directly integrating the full wave-equation, we use the symmetry of the metric to reduce the problem to that of an ODE. We observe that, around the total evaporation point, quasi-normal like oscillations appear, indicating that this may be an interesting model for the description of the end-point of black hole evaporation.

High-order control for symplectic maps

description: We revisit the problem of introducing an a priori control for devices that can be modeled via a symplectic map in a neighborhood of an elliptic equilibrium. Using a technique based on Lie transform methods we produce a normal form algorithm that avoids the usual step of interpolating the map with a flow. The formal algorithm is completed with quantitative estimates that bring into evidence the asymptotic character of the normal form transformation. Then we perform an heuristic analysis of the dynamical behavior of the map using the invariant function for the normalized map. Finally, we discuss how control terms of different orders may be introduced so as to increase the size of the stable domain of the map. The numerical examples are worked out on a two dimensional map of Hénon type.

description: J. K. G. (Jim) Watson was a world-leading authority on the basic theory of molecular rotation and vibration, especially renowned for his simplification of the rotational and rotation–vibration Hamiltonians (energy expressions). Other significant scientific achievements include the treatment of ‘forbidden’ rotational transitions in symmetric molecules and analysis of the spectrum of the H+3 molecular ion, both of which have important astrophysical implications. Jim was a reticent individual who carried out much of his most important research solo, while at the same time he had a wide circle of collaborators who were often experimentalists seeking theoretical guidance. Although his most profound contributions were highly mathematical, he always endeavoured to present the ultimate results in a widely useful form.

description: Introduction: Menopause, defined as 12 consecutive months without menstruation, is amajor milestone for women. With increasing life expectancy in India, focusing onmenopause health, developing resources, and educating women about symptoms andtreatments is essential. The Menopause-Specific Quality of Life Questionnaire (MENQOL) assesses the impact of menopause on quality of life, highlighting the need forbetter knowledge and a positive attitude for improved health outcomes. Methodology:This cross-sectional descriptive study, conducted at SMS Medical College, Jaipur, usedthe MEN-QOL questionnaire to evaluate menopausal women. Results: The average ageof menopause was found to be 48.5 ± 4.4 years. Rural women reported physicalsymptoms (76%) as most bothersome, while urban women experienced vasomotorsymptoms (66%) more prominently. The study revealed a significant knowledge gapamong postmenopausal women.Conclusion: The research indicated that inadequateknowledge and mindset regarding menopause adversely affected women's quality oflife. Thus, improving education and attitudes about menopause is crucial.
