Text mining

description: The goal of this study is to evaluate the differences in readability and content between U.S. drug Package Inserts (PI) and Consumer Medical Information Leaflets (CMI).  Using text mining techniques such as Natural Language Processing with the UMLS MetaMap, and document metrics such as the Flesch-Kincaid grade level score, a sample of PI and CMI will be examined for 35 common drugs in the U.S.     Text Mining allows for mapping of text into Concept Unique Identifiers, which allows for comparison of text between documents with different vocabularies.  As Package Inserts are written for professionals, and CMI Leaflets are written for consumers, this technique lends itself well to compare content.    This study shows that recall is appropriately low when comparing CMI Leaflets to Package Inserts: omitted concepts are more important for physicians and pharmacists than patients.  Readability is high for CMI Leaflets, but more effort should be made to express contraindications.

Ghost in the time series: no planet for Alpha Cen B

description: We re-analyse the publicly available radial velocity (RV) measurements for Alpha Cen B, a star hosting an Earth-mass planet candidate, Alpha Cen Bb, with 3.24 day orbital period. We demonstrate that the 3.24 d signal observed in the Alpha Cen B data almost certainly arises from the window function (time sampling) of the original data. We show that when stellar activity signals are removed from the RV variations, other significant peaks in the power spectrum of the window function are coincidentally suppressed, leaving behind a spurious yet apparently-significant 'ghost' of a signal that was present in the window function's power spectrum to begin with. Even when fitting synthetic data with time sampling identical to the original data, but devoid of any genuine periodicities close to that of the planet candidate, the original model used to infer the presence of Alpha Cen Bb leads to identical conclusions: viz., the 3$σ$ detection of a half-a-metre-per-second signal with 3.236 day period. Our analysis underscores the difficulty of detecting weak planetary signals in RV data, and the importance of understanding in detail how every component of an RV data set, including its time sampling, influences final statistical inference.

description: We find two relations between coherence and path-information in a multi-path interferometer. The first builds on earlier results for the two-path interferometer, which used minimum-error state discrimination between detector states to provide the path information. For visibility, which was used in the two-path case, we substitute a recently defined $l_{1}$ measure of quantum coherence. The second is an entropic relation in which the path information is characterized by the mutual information between the detector states and the outcome of the measurement performed on them, and the coherence measure is one based on relative entropy.
description: The original result has been strengthened, an entropic duality relation has been added, and an author has been added. The title has also been modified

description: This study examined the use of HTML meta tags for embedding metadata in World Wide Web resources. While many metadata initiatives that organize and facilitate resource discovery have been successful in organizational and corporate environments, little work has been done to determine whether or not Web resource creators are using metadata. This study examined the HTML source code for 299 web pages to provide a snapshot of how embedded metadata is being used on the Web and used a survey to explore the reasons why resource creators do or do not use metadata. The results found that 71% of the pages examined contained metadata, but very little of it conformed to any metadata standard. The survey results indicated that the majority of respondents did not grasp the larger context of metadata outside of its use on the web, and that they were unfamiliar with the concept of a metadata standard. These findings suggest that to improve the amount and quality of metadata used in web pages, resource creators should be given a context larger than the web in order to understand its value. Additionally, search engines need to get involved by providing metadata field-searching capabilities.

description: Stellar seismology appears more and more as a powerful tool for a better determination of the fundamental properties of solar-type stars. However the particular case of Sun is still challenging. The helioseismic sound speed determination continues to disagree with the Standard Solar Model (SSM) prediction for about a decade, questioning the reliability of this model. One of the sources of uncertainty could be in the treatment of the transport of radiation from the solar core to the surface. In this letter, we use the new OPAS opacity tables, recently available for solar modelling, to address this issue. We discuss first the peculiarities of these tables, then we quantify their impact on the solar sound speed and density profiles using the reduced OPAS tables taken on the grids of the OPAL ones. We use the two evolution codes MESA and CLES that led to similar conclusions in the solar radiative zone. In comparison to commonly used OPAL opacity tables, the new solar models computed, for the most recent photospheric composition, with OPAS tables present improvements in the location of the base of the convective zone and in the description of the solar radiative zone in comparison to the helioseismic observations, even if the differences in the Rosseland mean opacity do not exceed 6 %. We finally carry out a comparison to a solar model computed with the OP opacity tables.

description: Hydrodynamics and transport simulations were conducted with the modeling software TELEMAC-2D on Icó-Mandantes bay, a branch of the Itaparica reservoir. The bay has a maximal operational water level amplitude of 5 m and is suffering from eutrophication and algae bloom. Therefore, we investigated low and high water level scenarios with two different high resolution meshes, with the purpose to deeper understand their impact on transport of substances and to improve the watershed management. In particular, nutrient emissions from a hypothetical net cage aquaculture system located in the bay were investigated on half-year cycles. We observed a relevant impact on water quality for a tilapia production of 130 t y−1; i.e. after 6 months' simulation we obtained around 8 μgP L−1 and 6 μgP L−1 at the source of emissions, for low and high water scenarios, respectively.

description: We show that information about scattering data of a quantum field theory can be obtained from studying the system at finite density and low temperatures. In particular we consider models formulated on the lattice which can be exactly dualized to theories of conserved charge fluxes on lattice links. Apart from eliminating the complex action problem at nonzero chemical potential mu, these dualizations allow for a particle world line interpretation of the dual fluxes from which one can extract data about the 2-particle wave function. As an example we perform dual Monte Carlo simulations of the 2-dimensional O(3) model at nonzero mu and finite volume, whose non-perturbative spectrum consists of a massive triplet of particles. At nonzero mu particles are induced in the system, which at sufficiently low temperature give rise to sectors of fixed particle number. We show that the scattering phase shifts can be obtained either from the critical chemical potential values separating the sectors or directly from the wave function in the 2-particle sector. We find that both methods give excellent agreement with the exact result. We discuss the applicability and generality of the new approaches.

description: Here, we introduce a customized hanging insert fitting a six-well plate to culture Caco-2 cells on hydrogel membranes under flow conditions. The cells are cultured in the apical channel-like chamber, which provides about 1.3 dyn/cm2 shear, while the basolateral chamber is mixed when the device is rocked. The device was tested by investigating the functional impact of the initial seeding density in combination with flow applied at confluency. The low seeding density cultures grew in two dimensional (2D) irrespective of the flow. Flow and higher seeding density resulted in a mixture of three dimensional (3D) structures and 2D layers. Static culture and high cell seeding density resulted in 2D layers. The flow increased the height and ZO-1 expression of cells in 2D layers, which correlated with an improved barrier function. Cultures with 3D structures had higher ZO-1 expression than 2D cultures, but this did not correlate with an increased barrier function. 2D monolayers in static and dynamic cultures had similar morphology and heterogeneity in the expression of Mucin-2 and Villin, while the 3D structures had generally higher expression of these markers. The result shows that the cell density and flow determine 3D growth and that the highest barrier function was obtained with low-density cultures and flow.

 Type:— COSTA RICA. Heredia, Hacienda Santiago, adjacent to east side of La Selva, near Puerto Viejo, Sarapiquí, 29 May1973, G. S. Hartshorn 1238 (holotype: F-1721187!; isotypes: CR, F-1854142!).
 Hemi-epiphyte trees 12–50 m tall. Leaf blade 8.0– 12 cm long, 4.0–6.0 cm wide, elliptic, base obtuse to cuneate, apex obtuse to rounded, rare acute, adaxial face smooth and glabrous, abaxial face puberulent; secondary veins 10–24 (–40) pairs; petiole 1.0–3.0 cm long, glabrous, periderm persistent; stipules 1.5–4.0 cm long, caducous, puberulent. Syconia solitary, peduncle 4.0– 10 mm long, puberulent; lateral bracts absent; receptacle 1.2–2.0 cm diam. when dry (in vivo, to 3.5 cm), puberulent, apex rounded (Fig. 3B, C).
 Distribution and habitat in Colombia: —Chocó, and Valle del Cauca, in lowland and premontane rainforests at elevations of 60–1000 m (Fig. 2).
 Selected specimens: — COLOMBIA. CHOCÓ: Playa de Oro, leste de Tado, Juncosa 2515 (JAUM).— VALLE DEL CAUCA: Buenaventura, San Isidro, Devia 2716 (US).
 Notes:— Ficus crassivenosa was treated as a synonym of F. crassiuscula in Berg & Simonis (2000), Berg & Villavicencio (2004) and Berg (2009); however, the former differs from the latter by its early growth habit (hemi-epiphyte vs. terrestrial), size of the stipule (1.5–4.0 vs. 4.5–6.5 cm), length of the blade (8.0–12 vs. 12–17 cm), peduncle length (4–10 vs. 15–25 mm), basal bracts size (1.0–2.0 vs. 3.0–6.0 mm), size of receptacle (1.2–2.0 vs. 2.7–3.5 cm), and habitat altitude (60–1000 m vs. 1500–2400 m). Burger (1977) maintained Ficus crassivenosa as a distinct taxon citing its early hemi-epiphytic growth form. This is an important feature in Ficus taxonomy which defines sections such as F. sect. Americanae.

description: We prove that the Gromov width of coadjoint orbits of the symplectic group is at least equal to the upper bound known from the works of Zoghi and Caviedes. This establishes the actual Gromov width. Our work relies on a toric degeneration of a coadjoint orbit to a toric variety. The polytope associated to this toric variety is a string polytope arising from a string parametrization of elements of a crystal basis for a certain representation of the symplectic group.

description: We present spectral and timing analysis of NuSTAR observations of the accreting X-ray pulsar 2RXP J130159.6-635806. The source was serendipitously observed during a campaign focused on the gamma-ray binary PSR B1259-63 and was later targeted for a dedicated observation. The spectrum has a typical shape for accreting X-ray pulsars, consisting of a simple power law with an exponential cutoff starting at ~7 keV with a folding energy of E_fold=~18 keV. There is also an indication of the presence of a 6.4 keV iron line in the spectrum at the ~3 sigma significance level. NuSTAR measurements of the pulsation period reveal that the pulsar has undergone a strong and steady spin-up for the last 20 years. The pulsed fraction is estimated to be ~80%, and is constant with energy up to 40 keV. The power density spectrum shows a break towards higher frequencies relative to the current spin period. This, together with steady persistent luminosity, points to a long-term mass accretion rate high enough to bring the pulsar out of spin equilibrium.

description: This is an exploratory study that investigates desirable characteristics for a seller to possess in an on-line auction setting based on buyer's written feedback comments and ratings from positive to negative on the online auction site eBay. It was conducted to determine the common characteristics that buyers write about and to expand the traditional feedback rating system for sellers from one-dimensional to a multi-dimensional. Five hundred comments written by unique buyers about a hundred sellers were gathered from eBay on September 9, 2004. Content Analysis was used to analyze the comments and ratings once they were transferred to an excel spreadsheet. In these online auctions buyer's comments on feedback ratings systems are what other buyers use to help determine if they are going to purchase an item from the seller. The current types of feedback rating systems do not offer the ability to rank a seller on multiple characteristics that are important to the buyer. This lack of consistency in determining the seller's expected performance is a major factor in the public's reluctance to adopt electronic commerce as a means to purchase items.

description: A novel method and nanodevice are introduced that allows to rotate the single electron spin confined in a gated electrostatic InSb nanowire quantum dot. Proposed method does not require application of any (oscillating or static) external magnetic fields. Our proposal instead employs spatial and time modulation of confining potential induced by electric gates, which, in turn leads to oscillating Rashba type spin-orbit coupling. Moving electron back and forth in such a variable Rashba field allows for realization of spin rotations around two different axes separately without using an external magnetic field. The results are supported by realistic three-dimensional time dependent Poisson-Schrödinger calculations for systems and material parameters corresponding to experimentally accessible structures.

description: In a previous article, we obtained data on the distribution of traces of Frobenius of non-hyperelliptic genus $3$ curves over small finite fields. In the present one, we give a heuristic explanation of these data, by extrapolating from results on the distribution of traces of Frobenius for plane curves whose degree is small with respect to the cardinality of their finite base field. In particular, our methods shed some new light on the asymmetry of the distribution around its mean value, which is related to the Serre obstruction.

description: In 2010, entrepreneurial innovation emerged as the theme for a $125 million
fundraising initiative at the University of North Carolina at Chapel Hill. The
leaders of the initiative argue that if universities embrace entrepreneurial
thinking then these “engines of innovation” are poised to help solve some of
the world’s biggest problems. In this paper, I argue that the blueprint for such
an engine is far from complete, especially where the role of graduate students is
concerned. Over the course of my Master’s program, I tried to launch a venture
to build a community-owned “social archive site” for poverty alleviation. This
paper is a case study of that entrepreneurial effort and the barriers to innovation
I encountered.
Stability of the electroweak ground state in the Standard Model and its extensions

description: We review the formalism by which the tunnelling probability of an unstable ground state can be computed in quantum field theory, with special reference to the Standard Model of electroweak interactions. We describe in some detail the approximations implicitly adopted in such calculation. Particular attention is devoted to the role of scale invariance, and to the different implications of scale-invariance violations due to quantum effects and possible new degrees of freedom. We show that new interactions characterized by a new energy scale, close to the Planck mass, do not invalidate the main conclusions about the stability of the Standard Model ground state derived in absence of such terms.

Intellectual Property

description: The purpose of this research is to gain a greater understanding of the factors that influence library and information science (LIS) students' views on intellectual property rights, specifically illegal reuse of content on the web. The study utilizes interviews and surveys to explore attitudes toward illegal downloading of digital content in general, extent of ethics education in LIS classes, disciplinary differences between information and library science, and these variables' influence on attitudes towards illegal reuse of copyrighted content analyzed for correlation. The end result of this study is an exploration of the attitudes about intellectual property rights in the next generation of librarians to determine future areas of improvement (e.g., required ethics trainings for future librarians and information science workers; specific ways LIS programs can emphasize intellectual property concerns).

description: We explore the radial velocity performance benefits of coupling starlight to a fast-scanning interferometer and a fast-readout spectrometer with zero readout noise. By rapidly scanning an interferometer we can decouple wavelength calibration errors from precise radial velocity measurements, exploiting the advantages of lock-in amplification. In a Bayesian framework, we investigate the correlation between wavelength calibration errors and resulting radial velocity errors. We construct an end-to-end simulation of this approach to address the feasibility of achieving 10 cm/s radial velocity precision on a typical Sun-like star using existing, 5-meter-class telescopes. We find that such a precision can be reached in a single night, opening up possibilities for ground-based detections of Earth-Sun analog systems.

description: Am 10. März 1959 erhoben sich in Tibet tausende Menschen gegen die chinesische Besatzung. Der Aufstand wurde blutig niedergeschlagen, und der Dalai Lama flüchtete am 17. März ins Exil nach Indien. Heute leben von den insgesamt knapp sechs Millionen Tibetern etwa 120 000 im indischen Exil. Viele davon sind politisch engagiert und hoffen, eines Tages in die alte Heimat zurückkehren zu können. Doch über das Wie und die Frage des Umgangs mit der chinesischen Regierung gibt es innerhalb der tibetischen Diaspora erhebliche Differenzen.

Copyright

description: Within the last few years, academic libraries have begun to introduce electronic reserve services. Law libraries are naturally suited to this type of service because law schools have included digital materials in the curriculum for many years. The convenient access provided by electronic reserves makes their use inevitable. Whether these materials are in a formal electronic reserve collection or are mounted on faculty homepages, the same legal concerns exist. Placing them under the auspices of the library aids ease of control and helps minimize any legal exposure that the law school may incur. This paper discusses the advantages and disadvantages of electronic reserves, the Copyright Law, relevant past litigation, current reserve room policies, and suggested new standards. In conclusion, the paper looks at where the law in this area is likely to move and what response will best serve law libraries.

 Notes:— There are three specimens of Ficus gigantosyce labelled as type in the Herbario Nacional Colombiano; i.e. COL 3915, COL 3916, COL 407615. Since Dugand (1942) did not label these specimens as being part of the same specimens they are considered as duplicates and a lectotype must be chosen (Art. 9.1 and 9.2). We chose the specimen COL 3916 because it has stipules and a syconium, which are informative characters.

description: We propose a computational framework for the self-consistent dynamics of a microsphere system driven by a pulsed acoustic field in an ideal fluid. Our framework combines a molecular dynamics integrator describing the dynamics of the microsphere system with a time-dependent integral equation solver for the acoustic field that makes use of fields represented as surface expansions in spherical harmonic basis functions. The presented approach allows us to describe the inter-particle interaction induced by the field as well as the dynamics of trapping in counter-propagating acoustic pulses. The integral equation formulation leads to equations of motion for the microspheres describing the effect of non-dissipative drag forces. We show (1) that the field-induced interactions between the microspheres give rise to effective dipolar interactions, with effective dipoles defined by their velocities, and (2) that the dominant effect of an ultrasound pulse through a cloud of microspheres gives rise mainly to a translation of the system, though we also observe both expansion and contraction of the cloud determined by the initial system geometry.

description: Application profiles are a tool to describe metadata element sets that are combined for robust resource description. These profiles are often expressed in either human readable and/or machine-understandable formats and stored in metadata registries. This is a two-phase study. Phase one is an analysis of nineteen application profiles contained within two registries. The analysis was conducted to determine the kinds of information about element usage included in registered versions of application profiles. Phase two is an analysis of profile documentation published by authorized organizations responsible for profile development and maintenance. This phase of the study gathers additional information about usage. The research identifies four types of changes that profiles are applying to elements: data type, obligation, definition/name, and scheme. Details of these four categories are discussed and conclusions are drawn regarding their significance to metadata interoperability on the web.
Comparing two statistical ensembles of quadrangulations: a continued fraction approach

description: We use a continued fraction approach to compare two statistical ensembles of quadrangulations with a boundary, both controlled by two parameters. In the first ensemble, the quadrangulations are bicolored and the parameters control their numbers of vertices of both colors. In the second ensemble, the parameters control instead the number of vertices which are local maxima for the distance to a given vertex, and the number of those which are not. Both ensembles may be described either by their (bivariate) generating functions at fixed boundary length or, after some standard slice decomposition, by their (bivariate) slice generating functions. We first show that the fixed boundary length generating functions are in fact equal for the two ensembles. We then show that the slice generating functions, although different for the two ensembles, simply correspond to two different ways of encoding the same quantity as a continued fraction. This property is used to obtain explicit expressions for the slice generating functions in a constructive way.
