description: We consider a charged particle moving in a static electromagnetic field described by the vector potential $\vec A(\vec x)$ and the electrostatic potential $V(\vec x)$. We study the conditions on the structure of the integrals of motion of the first and second order in momenta, in particular how they are influenced by the gauge invariance of the problem. Next, we concentrate on the three possibilities for integrability arising from the first order integrals corresponding to three nonequivalent subalgebras of the Euclidean algebra, namely $(P_1,P_2)$, $(L_3,P_3)$ and $(L_1,L_2,L_3)$. For these cases we look for additional independent integrals of first or second order in the momenta. These would make the system superintegrable (minimally or maximally). We study their quantum spectra and classical equations of motion. In some cases nonpolynomial integrals of motion occur and ensure maximal superintegrability.

Academic libraries--Collection development

description: This paper presents research on the collection status of four different open access scholarly electronic resources in the humanities - the Stanford Encyclopedia of Philosophy, the Perseus Digital Library, the William Blake Archive, and NINES - among 110 university library members of the Association of Research Libraries (ARL). The necessity of collecting these resources not due to the building of a permanent collection of materials, which is likely impossible with the current structure of scholarly electronic resources; it is a user service: by the act of providing an access point to open access resources, libraries provide the scholarly and academic context for patron experience in a manner that open web search cannot. Current aggregations like DOAJ and OpenDOAR are assessed, along with electronic resource management tools, in order to make recommendations toward facilitating the collection of high quality open access resources in ARL online public access catalogs (OPAC).

description: Understanding the competition between brittleness and plasticity in refractory ceramics is of importance for aiding design of hard materials with enhanced fracture resistance. Inspired by experimental observations of crack shielding due to dislocation activity in TiN ceramics [Int J Plast 27 (2011) 739], we carry out comprehensive atomistic investigations to identify mechanisms responsible for brittleness and slip-induced plasticity in Ti-N systems. First, we validate a semi-empirical interatomic potential against density-functional theory results of Griffith and Rice stress intensities for cleavage (KIc) and dislocation emission (KIe) as well as ab initio molecular dynamics mechanical-testing simulations of pristine and defective TiN lattices at temperatures between 300 and 1200 K. The calculated KIc and KIe values indicate intrinsic brittleness, as KIc<

description: We present several arguments which favor the scenario of two coexisting families of compact stars: hadronic stars and quark stars. Besides the well known hyperon puzzle of the physics of compact stars, a similar puzzle exists also when considering delta resonances. We show that these particles appear at densities close to twice saturation density and must be therefore included in the calculations of the hadronic equation of state. Such an early appearance is strictly related to the value of the L parameter of the symmetry energy that has been found, in recent phenomenological studies, to lie in the range $40

description: This study describes the political participation of a random sample of academic librarians in North Carolina as determined from analysis of mailed surveys that they completed. The questionnaire asked the study participants to answer questions testing their political knowledge, to rate the political participation of themselves and others, to respond to various statements about political participation, to describe their activities, and to give some demographic information about themselves. Major sections of the questionnaire were repeated from similar studies done in 1976 by Edward James Sheary and in 1966 by Frances Goins Wilhoit in order to assess the changes that have occurred in academic librarians' political participation over time. Throughout this study and the two prior studies, political participation is measured on a 5-level scale with values ranging from (1) No political participation to (5) Belonging to political groups or holding office.

description: In this paper we deal with the problems of the weak localization of the eigenfunction expansions related to Laplace-Beltrami operator on unit sphere. The conditions for weak localization of Fourier-Laplace series are investigated by comparing the Riesz and Cesaro methods of summation for eigenfunction expansions of the Laplace-Beltrami operator. It is shown that the weak localization principle for the integrable functions f(x) at the point x depends not only on behavior of the function around x but on the behavior of the function around diametrically opposite point \overline{x}.

description: The growth in digital resource repositories flickr and del.icio.us, mirrors the growth of Folksonomies to support resource classification and access. Despite this phenomenon, little is known about the effectiveness of folksonomy for retrieval and organization. Little is also known about their structure and the types of semantic relationships among folksonomy terms. This study analyzes folksonomy metadata for hierarchal semantic relationships via a content analysis of approximately 2000 folksonomy tags in over 600 individual entries. The terms were classified into groups and analyzed for hierarchical relationships. The results indicate that hierarchical relationships are part of Folksonomies. The conclusion briefly explores the potential value of thesauri for Folksonomy development, and the value of Folksonomies to thesauri developers.

description: We establish new results on the $\mathcal I$-approximation property for the Banach operator ideal $\mathcal I=\mathcal{K}_{up}$ of the unconditionally $p$-compact operators in the case of $1\le p<2$. As a consequence of our results, we provide a negative answer for the case $p=1$ of a problem posed by J.M. Kim (2017). Namely, the $\mathcal K_{u1}$-approximation property implies neither the $\mathcal{SK}_1$-approximation property nor the (classical) approximation property; and the $\mathcal{SK}_1$-approximation property implies neither the $\mathcal{K}_{u1}$-approximation property nor the approximation property. Here $\mathcal{SK}_p$ denotes the $p$-compact operators of Sinha and Karn for $p\ge 1$. We also show for all $2

This study evaluates the health information  and general content of TCU library web sites. The web sites of the fifteen TCU offering  programs in the health sciences were examined for representation of library services and  information, research and reference tools, instruction tools, functionality and design, and  health sciences information tools. The results were compared with previously published  data for other kinds of academic libraries. Most TCU library web sites have a strong  collection of library information and links to free research tools but lack instructional  tools, but many need to update their sites more frequently and improve their  organizational schemes.

Other Indigenous studies not elsewhere classified

description: This essay seeks to historically study the ideologies behind the formation and function of the indigenous Manki- Munda system in Kolhan region of the erstwhile Singhbhum district. During pre-colonial times, the institution
 developed as an autonomous system of social governance to bond the Ho community1
 and promote their welfare. This was co-opted by the British as a lower unit of Raj bureaucracy and invested with new rights and jurisdictions. The ideology at work was to consolidate colonial rule by creating the façade of ruling through the tribal social agencies. As elsewhere in India, the British rulers were inspired by the ‘civilizing mission’ that inaugurated a paternalistic regime, in which the traditional Manki-Munda system functioned as a political tool to promote the above purposes. After Indian independence, the system encountered the challenge of an alternative form of village governance known as Panchayeti Raj that systematically displaced it from the helm. Divided in three broad sections, the first section traces the genesis and development of the indigenous institution and its function as an agency of development and change. The second critically examines the process of the incorporation of the institution as a political tool to consolidate British colonialism, and promote change and development. The last postscripts the experiments that state and union governments have made since independence in mainstreamising and democratising the mechanism of rural governance and the final form that it took.

description: This study describes an online survey on the subject of floating collections that was sent out to members of the PUBLIB and PUBYAC listservs. The survey, which collected both quantitative and qualitative data, was conducted in order to determine how public librarians perceive the benefits and drawbacks of working with floating collections. The survey received 135 responses, 112 of which were complete. The respondents
represented both adult services and children's librarians. The results indicate that while there are benefits to working with floating collections, not all libraries experience them to the same degree, and the drawbacks are significant. Problems with redistribution, collection knowledge, and the ability to serve all patrons well emerged as major difficulties. The perception put forth by the literature- that benefits are widespread and the drawbacks both temporary and easily overcome-is not supported by the results of the survey.

description: We show that in each dimension $4n+3$, $n\ge 1$, there exist infinite sequences of closed smooth simply connected manifolds $M$ of pairwise distinct homotopy type for which the moduli space of Riemannian metrics with nonnegative sectional curvature has infinitely many path components. Closed manifolds with these properties were known before only in dimension seven, and our result does also hold for moduli spaces of Riemannian metrics with positive Ricci curvature. Moreover, in conjunction with work of Belegradek, Kwasik and Schultz, we obtain that for each such $M$ the moduli space of complete nonnegative sectional curvature metrics on the open simply connected manifold $M\times\mathbb {R}$ also has infinitely many components.

The Use of the Computer as an Aid to the Medium Sized Building Contractor
Creators: name: Howes, R
Publisher: name: London South Bank University
Year: 1977

description: The initial part of the thesis is constructed to establish the facts relating to electronic data processing applications by building contractors in England. A survey was conducted in 1974, the conclusions of which are included in the text. The second part of the study relates to the Industry as a whole, but with special consideration of the medium sized builder. Therefore, the analysis of just one actual company is considered not to be representative of the whole range of situations. Consequently the development of a fictitious model company which incorporates as many typical procedures and problems as realistically possible is included. By adopting this approach it is hoped that builders reading this thesis will be able to identify themselves with their procedures and problems. Following the analysis of the model company, an evaluation is made, the object of which is to form the basis for the development of a new system suitable for electronic data processing applications. The system proposals also attempt to identify improvements in productivity and efficiency, together with the viability of implementation. The research is designed to provide a method of developing an integrated management system utilising the concepts of data base and modular systems applied to the computer. Further, consideration is given to the typical builder's current situation and the necessity. to build up a computer based system at an appropriate rate to an adequate level of application. It is intended that this research will improve the knowledge of builders and computer consultants by acting as a medium by which each can identify the others problems. The object is to accelerate viable future electronic data processing applications in the Construction Industry, with special reference to the medium sized builder.

description: This study examines an asynchronous, form-based model of service for Readers' Advisory within a public library setting.  Literature addresses some limitations of the traditional model of Readers' Advisory service, including patron reluctance to approach librarians and time constraints for librarians handling multiple tasks and requests.  One potential solution to overcoming these limitations is providing an asynchronous, form-based model of Reader's Advisory service.  This study introduces a form-based model as an experimental service in a pilot-study with the Chapel Hill (NC) Public Library.  To assess the service model, data was collected through survey responses from study participants and interview responses from participant-librarians. Results demonstrate that patrons and library professionals benefit from the provision of a form-based model of Readers' Advisory service.  Suggestions for further research considering the form-based service model, and the professional development of Readers' Advisory skills for public librarians are included.

description: Many recent deep learning-based solutions have widely adopted the attention-based mechanism in various tasks of the NLP discipline. However, the inherent characteristics of deep learning models and the flexibility of the attention mechanism increase the models' complexity, thus leading to challenges in model explainability. In this paper, to address this challenge, we propose a novel practical framework by utilizing a two-tier attention architecture to decouple the complexity of explanation and the decision-making process. We apply it in the context of a news article classification task. The experiments on two large-scaled news corpora demonstrate that the proposed model can achieve competitive performance with many state-of-the-art alternatives and illustrate its appropriateness from an explainability perspective.

description: In nonsuperconducting, metallic paramagnetic SrCo2As2, inelastic neutron scattering measurements have revealed strong stripe-type $χ$(q) = ($π$,0) antiferromagnetic (AFM) spin correlations. Here, using nuclear magnetic resonance (NMR) measurements on 59Co and 75As nuclei, we demonstrate that stronger ferromagnetic (FM) spin correlations coexist in SrCo2As2. Our NMR data are consistent with density functional theory (DFT) calculations which show enhancements at both q = ($π$,0) and the in-plane FM q = 0 wavevectors in static magnetic susceptibility $χ$(q). We suggest that the strong FM fluctuations prevent superconductivity in SrCo2As2, despite the presence of stripe-type AFM fluctuations. Furthermore, since DFT calculations have consistently revealed similar enhancements of the $χ$(q) at both q = ($π$,0) and q = 0 in the iron-based superconductors and parent compounds, our observation of FM correlations in SrCo2As2 calls for detailed studies of FM correlations in the iron-based superconductors.

description: This project concerns the creation of an electronic music book based upon the eXtensible Mark-up Language (XML 1.0). It begins with a brief overview of the literature on the subject of music mark-up, and XML's relation to previous efforts in this area. There is a sizeable history of research in the electronic representation of music. This literature review is not comprehensive on all aspects of the subject. Rather it is concentrated upon the textual representation of electronically stored music, and how XML became the preferred file format. The project then demonstrates the steps taken by the author to create an XML file format that could be validated against a DTD or XML Schema, and an acceptable XSLT Stylesheet to display the song. The project will then close with a summary of possible directions for future development/research.

description: We will follow the two-families scenario described in the accompanying paper, in which compact stars having a very small radius and masses not exceeding about 1.5$M_\odot$ are made of hadrons, while more massive compact stars are quark stars. In the present paper we discuss the dynamics of the transition of a hadronic star into a quark star. We will show that the transition takes place in two phases: a very rapid one, lasting a few milliseconds, during which the central region of the star converts into quark matter and the process of conversion is accelerated by the existence of strong hydrodynamical instabilities, and a second phase, lasting about ten seconds, during which the process of conversion proceeds till the surface of the star via production and diffusion of strangeness. We will show that these two steps play a crucial role in the phenomenological implications of the model. We will discuss the possible implications of this scenario both for long and for short Gamma Ray Bursts, using the proto-magnetar model as the reference frame of our discussion. We will show that the process of quark deconfinement can be connected to specific observed features of the GRBs. In the case of long GRBs we will discuss the possibility that quark deconfinement is at the origin of the second peak present in quite a large fraction of bursts. Also we will discuss the possibility that long GRBs can take place in binary systems without being associated with a SN explosion. Concerning short GRBs, quark deconfinement can play the crucial role in limiting their duration. Finally we will shortly revisit the possible relevance of quark deconfinement in some specific type of Supernova explosions, in particular in the case of very massive progenitors.

We create narrow potentials using a tightly focused, red-detuned laser beam, and observe reflection of up to 25% of the atoms, along with the trapping of atoms at the position of the beam. We show that the observed reflected fraction is much larger than theoretical predictions for a narrow Gaussian potential well; a more detailed model of bright soliton propagation, accounting for the generic presence of small subsidiary intensity maxima in the red-detuned beam, suggests that these small intensity maxima are the cause of this enhanced reflection.

description: This study is an evaluation of the implementation of an Electronic Medical Record (EMR) at the Student Health Action Coalition (SHAC), a student-run free clinic. The implementation is evaluated in light of the constructs of performance expectancy, effort expectancy, and facilitating conditions presented in the Unified Theory for Acceptance and Use of Technology (UTAUT). The methodology encompassed nine one-on-one interviews with SHAC volunteers to learn their perspectives on the EMR. Findings show that use of and acceptance of the EMR at SHAC is influenced mainly by the performance and effort expectancy the volunteer associates with it and by the facilitating conditions supporting the system. Training volunteers more extensively on how to use the system may improve the efficiency of the EMR implementation. This research contributes to the field of medical informatics and may be of interest to other small clinics that are in the process of adopting and implementing an EMR.

description: Linear detectors such as zero forcing (ZF) or minimum mean square error (MMSE) are imperative for large/massive MIMO systems for both the downlink and uplink scenarios. However these linear detectors require matrix inversion which is computationally expensive for such huge systems. In this paper, we assert that calculating an exact inverse is not necessary to find the ZF/MMSE solution and an approximate inverse would yield a similar performance. This is possible if the quantized solution calculated using the approximate inverse is same as the one calculated using the exact inverse. We quantify the amount of approximation that can be tolerated for this to happen. Motivated by this, we propose to use the existing iterative methods for obtaining low complexity approximate inverses. We show that, after a sufficient number of iterations, the inverse using iterative methods can provide a similar error performance. In addition, we also show that the advantage of using an approximate inverse is not limited to linear detectors but can be extended to non linear detectors such as sphere decoders (SD). An approximate inverse can be used for any SD that requires matrix inversion. We prove that application of approximate inverse leads to a smaller radius, which in turn reduces the search space leading to reduction in complexity. Numerical results corroborate our claim that using approximate matrix inversion reduces decoding complexity in large/massive MIMO systems with no loss in error performance.

description: In this article, we show the existence of a nonnegative solution to the singular problem $(\mc P_\la)$ posed in a bounded domain $Ω$ in $\mb R^2$ (see below). We achieve this by approximating the singular function $u^{-β}\log(u)$ by a function $l_\e(u)$ which pointwisely converges to $-u^β\log(u)$ as $\e \ra 0$. Using variational techniques, the perturbed equation $-\De u+l_\e(u)=\ds\la \left(\I{\Om}\frac{F(u(y))}{|x-y|^μ}dy\right)f(u(x))$ is shown to have a solution $u_\e \in H_0^{1}(\Om)$ when the parameter $\la >0$ is small enough. Letting $\e \ra 0$ and proving a pointwise gradient estimate, we show that the solution $u_\e$ converges to a nontrivial nonnegative solution of the original problem $(\mc P_\la)$.

description: This paper addresses the problem of estimating the Hurst exponent of the fractional Brownian motion from continuous time noisy sample. Consistent estimation in the setup under consideration is possible only if either the length of the observation interval increases to infinity or intensity of the noise decreases to zero. The main result is a proof of the Local Asymptotic Normality (LAN) of the model in these two regimes, which reveals the optimal minimax rates.

description: We are conducting a survey for pulsars and transients using the Giant Metrewave Radio Telescope (GMRT). The GMRT High Resolution Southern Sky (GHRSS) survey is an off-Galactic-plane (|b|>5) survey in the declination range -40 deg to -54 deg at 322 MHz. With the high time (up to 30.72 micro-sec) and frequency (up to 0.016275 MHz) resolution observing modes, the 5-sigma detection limit is 0.5 mJy for a 2 ms pulsar with 10% duty cycle at 322 MHz. Total GHRSS sky coverage of 2866 square-deg, will result from 1953 pointing, each covering 1.8 square-deg. The 10-sigma detection limit for a 5 milli-sec transient burst is 1.6 Jy for the GHRSS survey. In addition, the GHRSS survey can reveal transient events like rotating radio transients or fast radio bursts. With 35% of the survey completed (i.e. 1000 square-deg), we report the discovery of 10 pulsars, one of which is a millisecond pulsar (MSP), one of the highest pulsar per square degree discovery rates for any off-Galactic plane survey. We re-detected 23 known in-beam pulsars. Utilising the imaging capability of the GMRT we also localised 4 of the GHRSS pulsars (including the MSP) in the gated image plane within +/- 10 arc-second. We demonstrated rapid convergence in pulsar timing with a more precise position than is possible with single dish discoveries. We also exhibited that we can localise the brightest transient sources with simultaneously obtained lower time resolution imaging data, demonstrating a technique that may have application in the SKA.

description: This study describes a survey conducted with undergraduate student at the University of North Carolina at Chapel Hill during the Spring semester of 2014. The study investigates the student's knowledge of health and wellness materials at the UNC-CH libraries and whether or not the students would be likely to use these materials more if they were located at the student recreation centers.
The study found that the majority of respondents were not aware of the health and wellness materials at the library on campus. The study also found that the responses given for whether or not the students would be likely to use health and wellness materials at the student recreation centers were inconclusive and indicates a need for further study.

description: We study the weak decay of the $Λ_b$ into $ J/ψ~ K ~ Ξ$ and $J/ψ~ η~ Λ$ states, and relate these processes to the $Λ_b \to J/ψ~ \bar K ~N$ decay mode. The elementary weak transition at the quark level proceeds via the creation of a $J/ψ$ meson and an excited $sud$ system with $I=0$, which upon hadronization leads to $\bar K N$ or $ηΛ$ pairs. These states undergo final state interaction in coupled channels and produce a final meson-baryon pair. The $K Ξ$ state only occurs via rescattering, hence making the $Λ_b \to J/ψ~ K ~ Ξ$ process very sensitive to the details of the meson-baryon interaction in strangeness $S=-1$ and isospin $I=0$. We show that the corresponding invariant mass distribution is dominated by the next-to-leading order terms of the chiral interaction. The $I=0$ selectivity of this decay, and its large sensitivity to the higher order terms, makes its measurement very useful and complementary to the $K^- p \to K Ξ$ cross section data. The rates of the $Λ_b \to J/ψ~ K ~ Ξ$ and $Λ_b \to J/ψ~ η~ Λ$ invariant mass distributions are sizable compared to those of the $Λ_b \to J/ψ~ \bar K ~N$ decay, which is measured experimentally, thus, we provide arguments for an experimental determination of these decay modes that will help us understand better the chiral dynamics at higher energies.

Double quantum dot coupled to a quantum point contact: A stochastic thermodynamics approach

description: We study the nonequilibrium properties of an electronic circuit composed of a double quantum dot (DQD) channel coupled to a quantum point contact (QPC) within the framework of stochastic thermodynamics. We show that the transition rates describing the dynamics satisfy a nontrivial local detailed balance (LDB) and that the statistics of energy and particle currents across both channels obeys a fluctuation theorem (FT). We analyze two regimes where the device operates as a thermodynamic machine and study its output power and efficiency fluctuations. We show that the electrons tunneling through the QPC without interacting with the DQD have a strong effect on the device efficiency.
Towards the understanding of the genuine three-body interaction for p$-$p$-$p and p$-$p$-Λ$

description: Three-body nuclear forces play an important role in the structure of nuclei and hypernuclei and are also incorporated in models to describe the dynamics of dense baryonic matter, such as in neutron stars. So far, only indirect measurements anchored to the binding energies of nuclei can be used to constrain the three-nucleon force, and if hyperons are considered, the scarce data on hypernuclei impose only weak constraints on the three-body forces. In this work, we present the first direct measurement of the p$-$p$-$p and p$-$p$-Λ$ systems in terms of three-particle correlation functions carried out for pp collisions at $\sqrt{s} = 13$ TeV. Three-particle cumulants are extracted from the correlation functions by applying the Kubo formalism, where the three-particle interaction contribution to these correlations can be isolated after subtracting the known two-body interaction terms. A negative cumulant is found for the p$-$p$-$p system, hinting to the presence of a residual three-body effect while for p$-$p$-Λ$ the cumulant is consistent with zero. This measurement demonstrates the accessibility of three-baryon correlations at the LHC.

description: We calculate elastic scattering of positronium (Ps) by the Xe atom using the recently developed pseudopotential method [I. I. Fabrikant and G. F. Gribakin, Phys. Rev. A 90, 052717 (2014)] and review general features of Ps scattering from heavier rare-gas atoms: Ar, Kr, and Xe. The total scattering cross section is dominated by two contributions: elastic scattering and Ps ionization (breakup). To calculate the Ps ionization cross sections we use the binary-encounter method for Ps collisions with an atomic target. Our results for the ionization cross section agree well with previous calculations carried out in the impulse approximation. Our total Ps-Xe cross section, when plotted as a function of the projectile velocity, exhibits similarity with the electron-Xe cross section for the collision velocities higher than 0.8 a.u., and agrees very well with the measurements at Ps velocities above 0.5 a.u.
