description: Substrate and nanotube polarization are shown to change qualitatively a nanotube bandstructure. The effect is studied in a linear approximation in an external potential which causes the changes. A work function difference between the nanotube and gold surface is estimated to be large enough to break the band symmetry and lift a degeneracy of a lowest but one subband of a metallic nanotube. This subband splitting for [10,10] nanotube is about 50 meV in absence of other external potential.

description: Tropical coral reefs offer a wide variety of habitats to countless invertebrate species. Sessile host organisms especially are inhabited by small taxa, of which decapod crustaceans form one of the most diverse communities. Symbiotic palaemonid shrimp species associate with marine invertebrate hosts from multiple phyla, including cnidarians such as stony corals (Scleractinia). The intriguing gall-forming shrimp Paratypton siebenrocki, a symbiont of Acropora corals in the Indo-Pacific, was collected in the Saudi Arabian Red Sea, Kenya, and the Maldives. Based on morphology P. siebenrocki has been considered to be most closely related to the genera Anapontonia and Metapontonia; however, no clear clustering with either palaemonid genus was observed in a phylogenetic reconstruction based on 16S and COI mtDNA. Here we photo-document the dwellings of P. siebenrocki in Acropora spp. for the first time, and furthermore we report on the reproductive output of this species. The number of eggs ranged from 345 to 909 (n = 6), and embryo volume differed strongly between early- and late-stage embryos. The carapace length ranged from 2.58 to 4.55 mm for the females and 1.51 to 2.5 mm for the males (n = 5). The number and size of the embryos, combined with their specialised, secluded lifestyle, suggest that P. siebenrocki allocates higher energy towards embryo production than free-living confamilials do.

description: The global economic effects of eliminating certain significant categories of non- tariff measures (NTMs) are estimated in a CGE context. As a first step, a database of institutional information identifying alleged instances of NTMs for particular products and countries is constructed based on WTO, U.S. Government, and EU sources, and compared with the UNCTAD policy inventory. This database is then concorded to a GTAP-feasible multiregion, multisector aggregation. Retail price data from the EIU CityData database, similarly concorded, are analyzed econometrically, taking into account systematic deviations from purchasing-power parity, to determine whether and to what extent the presence of alleged NTMs is associated with significantly higher prices. The estimated price effects are then used to calibrate a CGE simulation in order to obtain simulation estimates of trade and welfare effects of their removal, which can be disaggregated. Removal of the categories of NTMs under consideration yields global gains on the order of $90 billion. These gains arise notably from liberalization by Japan and the European Union by region, and from liberalization of apparel and machinery/equipment by sector.

description: The analytical framework “heritage and patrimony of the peasantry” and its recommended implementation theoretically provide an enhancement over previous methodologies to examine rural development. The current paper measures rural development indicators in six Mexican rural territories, and analyses their interaction in the heritages and patrimonies of the peasantry. The principal indicators that affect the patrimonies in these regions were recognised as Pluriactivity, Social Acknowledgment, Biodiversity and Recycling. Based on these outcomes, the indicators that belong to the Human Patrimony define it as the lowest of all the heritages of the Mexican peasantry. The analysis of the results remarks on the fact that the emphasis of public policies on productive concerns has left out complicated social problems such as the loss of identity, diversity and culture. These matters are becoming the strongest threat affecting the Mexican peasantry to improve their quality of life while respecting their human rights.

description: Entanglement is a vital property of multipartite quantum systems, characterised by the inseparability of quantum states of objects regardless of their spatial separation. Generation of entanglement between increasingly macroscopic and disparate systems is an ongoing effort in quantum science which enables hybrid quantum networks, quantum-enhanced sensing, and probing the fundamental limits of quantum theory. The disparity of hybrid systems and the vulnerability of quantum correlations have thus far hampered the generation of macroscopic hybrid entanglement. Here we demonstrate, for the first time, generation of an entangled state between the motion of a macroscopic mechanical oscillator and a collective atomic spin oscillator, as witnessed by an Einstein-Podolsky-Rosen variance below the separability limit, $0.83 \pm 0.02<1$. The mechanical oscillator is a millimeter-size dielectric membrane and the spin oscillator is an ensemble of $10^9$ atoms in a magnetic field. Light propagating through the two spatially separated systems generates entanglement due to the collective spin playing the role of an effective negative-mass reference frame and providing, under ideal circumstances, a backaction-free subspace; in the experiment, quantum backaction is suppressed by 4.6 dB. Our results pave the road towards measurement of motion beyond the standard quantum limits of sensitivity with applications in force, acceleration,and gravitational wave detection, as well as towards teleportation-based protocols in hybrid quantum networks.

description: We investigate the shot noise of nonequilibrium carriers injected into a ballistic conductor and interacting via long-range Coulomb forces. Coulomb interactions are shown to act as an energy analyzer of the profile of injected electrons by means of the fluctuations of the potential barrier at the emitter contact. We show that the details in the energy profile can be extracted from shot-noise measurements in the Coulomb interaction regime, but cannot be obtained from time-averaged quantities or shot-noise measurements in the absence of interactions.

description: The neotropical apoid wasp genus Microstigmus is of particular interest biologically because it represents an origin of eusociality independent of vespid wasps and bees, and is part of the only eusocial lineage among the approximately 10,000 solitary species of apoid wasps. Females construct nests made of silk and the species exhibit an unusual diversity of nesting strategies. However, research is hampered because many species remain undescribed and the basic nesting biology of only a few species is known. I describe three new species from north-west Ecuador related to M. bicolor Richards, including diagnostic morphological characters, altitudinal ranges and molecular data as well as descriptions of their nests and nesting biologies. M. rosae sp. nov. is a mass provisioner that preys on nymphal Thysanoptera, while M. lydiae sp. nov. and M. mirandae sp. nov. are progressive provisioners that prey on nymphal leafhoppers (Cicadellidae). Nests of all three species can contain multiple adult females but more than half of nests contain only a single female. http://www.zoobank.org/urn:lsid:zoobank.org:pub:E46768B9-FD13-4370-8E31-8D1819B724F4
An empirical analysis of US and EU antidumping initiation and decision

description: This paper examines the relationship between antidumping procedures and macroeconomic factors, for both the US and EU. While recent research has considered the influence of domestic economic growth and exchange rate pressures on antidumping filings, this paper extends this work by using quarterly data and expanding the set of macroeconomic indicators to include the import penetration rate. Another contribution of this paper is to investigate more fully the rationale for a role of macroeconomic phenomena in explaining antidumping decisions by the relevant enforcement agencies. We use case-specific data for the US and the EU to investigate the macroeconomic and industry-level determinants of success. To the extent that macroeconomic indicators influence AD filing behavior (and success) in both the US and EU - implying that AD has become simply import protection rather than a remedy for unfair practices - it suggests the need for reform of WTO rules governing the administration of trade laws world-wide.

description: Catheters are the second most common abnormal finding on radiographs. The position of catheters must be assessed on all radiographs, as serious complications can arise if catheters are malpositioned. However, due to the large number of radiographs performed each day, there can be substantial delays between the time a radiograph is performed and when it is interpreted by a radiologist. Computer-aided approaches hold the potential to assist in prioritizing radiographs with potentially malpositioned catheters for interpretation and automatically insert text indicating the placement of catheters in radiology reports, thereby improving radiologists' efficiency. After 50 years of research in computer-aided diagnosis, there is still a paucity of study in this area. With the development of deep learning approaches, the problem of catheter assessment is far more solvable. Therefore, we have performed a review of current algorithms and identified key challenges in building a reliable computer-aided diagnosis system for assessment of catheters on radiographs. This review may serve to further the development of machine learning approaches for this important use case.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

On the Amount of Gravitational Waves from Inflation

description: The curvaton and the inhomogeneous reheating scenarios for the generation of the cosmological curvature perturbation on large scales represent an alternative to the standard slow-roll scenario where the observed density perturbations are due to fluctuations of the inflaton field itself. The basic assumption of the curvaton and inhomogeneous reheating mechanisms is that the initial curvature perturbation due to the inflaton field is negligible. This is usually attained by lowering the energy scale of inflation thereby concluding that the amount of gravitational waves produced during inflation is highly suppressed. We show, contrary to this common lore, that the curvaton and the inhomogeneous reheating scenarios are compatible with a level of gravity-wave fluctuations which may well be observed in future satellite experiments. This conclusion does not involve, as in the slow-roll inflationary models, embarrasingly large field variations in units of the Planck scale. As a working example, we illustrate the recently proposed stringy version of old inflation.

title: An investigation of the occurrence of antibiotic resistance genes among strains of Staphylococcus aureus isolated from animals and their relationship to human strains of Staphylococcus aureus
Creators: name: Robb, Andrew R.
Publisher: name: The Open University
Year: 2008

description: Data has emerged which indicates that antimicrobial use in animals has created a reservoir of resistant bacteria and resistance genes that have spread to humans.

The aim of this study was to examine the influence of animal antimicrobial use on human strains of S. aureus. Phenotypic and genotypic methods assessed the genetic population structure, potential for host adaptation, frequency of antimicrobial resistance, presence and frequency of genes encoding tetracycline and macrolide resistance and structural variation in tetK genes in S. aureus from animals compared with human clinical strains. In addition, the transferability of tetK resistance plasmids from animal strains to S. aureus 8325-4 was investigated.

DNA based typing exhibited 100% typeability, high levels of discrimination and a high degree of concordance between methods. Multi-locus sequence typing (MLST) identified six sequence types (CC5, CC15, CC22, CC25, CC30 and CC45) common to both isolate collections that represented four of the five major human methicillin resistant Staphylococcus aureus (MRSA) clonal lineages. The relatedness of these clones was further supported by the analysis of 20 different virulence determinants.

Isolates of CC5 exhibited resistance to ciprofloxacin, clindamycin, erythromycin, penicillin, streptomycin, tobramycin and tylosin, CC 15 to penicillin and tetracycline, CC22 to penicillin and rifampicin and CC30 to penicillin. Isolates of CC45 were fully susceptible. Low level biocide resistance was detected but the significance of this was unclear.

The tetK and ermC genes were the predominant tetracycline and macrolide resistance genes. tetK was harboured by animal isolates of CC5 and CC15 and ermC by animal isolates of CC5. Restriction fragment length polymorphism (RFLP) of tetK amplicons produced indistinguishable restriction patterns. High frequency transfer of a tetK plasmid from a chicken S. aureus (CC5) to S. aureus 8325-4 was observed.

These data support the hypothesis that animals represent an important reservoir of antibiotic resistant S. aureus with the ability for strain and antibiotic resistance gene transfer to humans.

The present work introduces a new estimator of the $CTE$ based on the bias-reduced estimators of high quantile for heavy-tailed distributions. The asymptotic normality of the proposed estimator is established and checked, in a simulation study. Moreover, we compare, in terms of bias and mean squared error, our estimator with the known old estimator.

description: Decalepis hamiltonii, Wight & Arn. (Apocyanaceae) is a one of the raw materials used in the preparation of ‘Pinda oil’, a medicinal oil which is used for treatment of wounds in Ayurveda. Of the hexanes, dichloromethane, and ethyl acetate extracts derived from the plant raw materials used to prepare ‘Pinda oil’, the hexanes extract of D. hamiltonii exhibited the highest mean percentage wound closure (75.1 ± 2.9) compared to the negative controls (1% DMSO in DMEM, 4.2 ± 1.2 and 100% DMEM, 4.1 ± 0.9) in the scratch wound assay (SWA). Fractionation of the hexanes extract of stem of D. hamiltonii led to the isolation of 2-hydroxy-4-methoxybenzaldehyde (1) and a mixture of long chain esters of lupeol (2), which showed enhanced cell migration in SWA. It was observed that the esters of lupeol bind to the cell membrane and/or enter the cells during the SWA. It was found that these constituents are also present in ‘Pinda oil’ which may contribute to the enhancement of wound healing activity of ‘Pinda oil’.

description: As multilateral negotiations focus more on reductions and removal of non-tariff barriers, the importance of quantifying the impact of these barriers has increased. While progress has been made recently, direct estimates of the impact of NTMs on prices has not been possible. This paper makes two contributions. First, price effects of NTMs are estimated directly, for many products in many countries. Second, explicit data on NTM incidence are drawn from two complementary databases—UNCTAD TRAINS data and a new NTM database compiled by the USITC. A simple differentiated product model of retail prices is developed to specify the direct relationship between NTMs and prices. From this model, a price gap specification is derived and estimated using retail price data for about 115 cities and 47 consumer products from the EIU CityData for 2001. The estimation yields both cross-country averages and country-specific estimates of the effects of NTMs, for more than 60 countries and four product groups in which NTM protection is of major importance: fruits and vegetables, bovine meats, processed food, and apparel.

description: “Frankenstein”, the novel composed by Mary Shelley, takes thoughts found in scholarly messages, minutes in time, and individuals and joins them into the novel to tell the confined story. Speculative chemistry and the chemists, albeit hardly referenced in the novel, are quintessential to the continuation of the plot. It is the chemists and their thoughts, especially those of Paracelsus and the idea of the solution of life, that move Victor Frankenstein to seek after the possibility of creation through science, at last driving Victor to the production of the animal in Frankenstein. Nevertheless, the paper traces out the elements of chemistry used in the novel.

description: A probability distribution over the Boolean cube is monotone if flipping the value of a coordinate from zero to one can only increase the probability of an element. Given samples of an unknown monotone distribution over the Boolean cube, we give (to our knowledge) the first algorithm that learns an approximation of the distribution in statistical distance using a number of samples that is sublinear in the domain. To do this, we develop a structural lemma describing monotone probability distributions. The structural lemma has further implications to the sample complexity of basic testing tasks for analyzing monotone probability distributions over the Boolean cube: We use it to give nontrivial upper bounds on the tasks of estimating the distance of a monotone distribution to uniform and of estimating the support size of a monotone distribution. In the setting of monotone probability distributions over the Boolean cube, our algorithms are the first to have sample complexity lower than known lower bounds for the same testing tasks on arbitrary (not necessarily monotone) probability distributions. One further consequence of our learning algorithm is an improved sample complexity for the task of testing whether a distribution on the Boolean cube is monotone.

description: As multilateral negotiations focus more on reductions and removal of non-tariff barriers, the importance of quantifying the impact of these barriers has increased. While progress has been made recently, direct estimates of the impact of NTMs on prices has not been possible. This paper makes two contributions. First, price effects of NTMs are estimated directly, for many products in many countries. Second, explicit data on NTM incidence are drawn from two complementary databases—UNCTAD TRAINS data and a new NTM database compiled by the USITC. A simple differentiated product model of retail prices is developed to specify the direct relationship between NTMs and prices. From this model, a price gap specification is derived and estimated using retail price data for about 115 cities and 47 consumer products from the EIU CityData for 2001. The estimation yields both cross-country averages and country-specific estimates of the effects of NTMs, for more than 60 countries and four product groups in which NTM protection is of major importance: fruits and vegetables, bovine meats, processed food, and apparel.

description: The effect of 0,224, 448 and 896 KgN/ha and 4,6, and 8-week cutting frequencies on yield, chemical composition and in vitro cellulose digestibility of Pangola grass was studied in a 32-week experiment. Increasing cutting frequency and Ν level resulted in decrease in DM and increase in CP contents. Cellulose tended to increase, and ADL to decrease as cutting decreased. Increasing Ν had little effect on cellulose, ADF, ADL or NDF. Decreasing cutting and increasing Ν increased DM yield. Yield of DM/unit Ν and of CP increased while 24-hour IVCD decreased as cutting decreased. Yield of CP and 24-hour IVCD increased with increasing levels of N.

description: Static packings of perfectly rigid particles are investigated theoretically and numerically. The problem of finding the contact forces in such packings is formulated mathematically. Letting the values of the contact forces define a vector in a high-dimensional space enable us to show that the set of all possible contact forces is convex, facilitating its numerical exploration. It is also found that the boundary of the set is connected with the presence of sliding contacts, suggesting that a stable packing should not have more than 2M-3N sliding contacts in two dimensions, where M is the number of contacts and N is the number of particles. These results were used to analyze packings generated in different ways by either molecular dynamics or contact dynamics simulations. The dimension of the set of possible forces and the number of sliding contacts agrees with the theoretical expectations. The indeterminacy of each component of the contact forces are found, as well as the an estimate for the diameter of the set of possible contact forces. We also show that contacts with high indeterminacy are located on force chains. The question of whether the simulation methods can represent a packing's memory of its formation is addressed.

description: The aim of the article was to present the relationship between the factors influencing the profitability of fruit and vegetable producers and organizations using the Du Pont model. Analysis was conducted on data from the financial statements of the aforementioned entities operating in the territory of the Kuyavian-Pomeranian voivodeship in the years 2005-2014. The results show a declining viability of existing units, which results from the high cost of servicing foreign capital, reduced profitability and reduced turnover of assets. These factors have resulted in negative financial leverage. However, despite unfavorable factors, the average return on equity over the period considered was positive. This allows for the possibility that, with sound financial management, producers and organizations of fruit and vegetable growers will in future have the opportunity to generate resources that will sustain and even develop a concentrated supply in this market. Increasing profitability of these units will also help satisfy the expectations of their members. / Synopsis. Celem artykułu było ukazanie relacji pomiędzy czynnikami kształtującymi rentowność kapitałów własnych grup i organizacji producentów owoców i warzyw za pomocą modelu Du Ponta. Analizy dokonano na podstawie danych ze sprawozdań finansowych w/w podmiotów funkcjonujących na terenie województwa kujawsko-pomorskiego w latach 2005-2014. Uzyskane wyniki wskazały na zmniejszającą się rentowność funkcjonujących jednostek, która wynikła z wysokich kosztów obsługi kapitału obcego, zmniejszonej zyskowności sprzedaży a także mniejszej rotacji posiadanych aktywów. Czynniki te powodowały iż mieliśmy do czynienia z ujemnym działaniem dźwigni finansowej. Mimo niesprzyjających czynników wartość średniego wskaźnika zwrotu z kapitału własnego w całym badanym okresie była dodatnia. Pozwala to sądzić, że przy odpowiednim zarządzaniu finansami grupy i organizacje producentów owoców i warzyw będą w przyszłości miały możliwość generować środki, które spowodują utrzymanie, a nawet rozwój koncentracji podaży na tym rynku. Zwiększenie zyskowności tych jednostek będzie miało przełożenie na zaspokojenie oczekiwań ich członków.

description: We calculate a current rectification by molecules containing a conjugated molecular group sandwiched between two saturated (insulating) molecular groups of different length (molecular quantum dot) using an ab-initio non-equilibrium Green's function method. In particular, we study S-(CH2)m-C10H6-(CH2)n-S dithiol with Naphthalene as a conjugated central group. The rectification current ratio ~35 has been observed at m = 2 and n = 10, due to resonant tunneling through the molecular orbital (MO) closest to the electrode Fermi level (lowest unoccupied MO in the present case). The rectification is limited by interference of other conducting orbitals, but can be improved by e.g. adding an electron withdrawing group to the naphthalene.

description: Exploratory information search can challenge users in the formulation of efficacious search queries. Moreover, complex information spaces, such as those managed by Geographical Information Systems, can disorient people, making it difficult to find relevant data. In order to address these issues, we developed a session-based suggestion model that proposes concepts as a "you might also be interested in" function, by taking the user's previous queries into account. Our model can be applied to incrementally generate suggestions in interactive search. It can be used for query expansion, and in general to guide users in the exploration of possibly complex spaces of data categories. Our model is based on a concept co-occurrence graph that describes how frequently concepts are searched together in search sessions. Starting from an ontological domain representation, we generated the graph by analyzing the query log of a major search engine. Moreover, we identified clusters of ontology concepts which frequently co-occur in the sessions of the log via community detection on the graph. The evaluation of our model provided satisfactory accuracy results.

description: We present the results of an investigation of the large scale structure of the diffuse interstellar medium in the 2nd Galactic Quadrant (90 <= l <= 180). 145 loops were identified on IRAS based far-infrared maps. Our catalogue lists their basic physical properties. The distribution clearly suggests that there is an efficient process that can generate loop-like features at high galactic latitudes. Distances are provided for 30 loops. We also give an observational estimate on the volume filling factor of the hot gas in the Local Arm, 4.6% <= f_2nd <= 6.4%

description: Gizis et al. (2001) reported a companion candidate of spectral type L1 near the K2 dwarf GJ 1048 using the Two Micron All-Sky Survey (2MASS). At that time it was not possible to verify companionship astrometrically using the 2MASS data alone due to the small proper motion of GJ 1048. We now show that both objects share the same proper motion by using data from the UK Schmidt Telescope Near-infrared (IVN) Southern Survey as the first epoch and data from 2MASS as the second epoch. Our technique of subtracting the PSF of the primary from the SuperCOSMOS I scans of the Southern Survey enables the astrometry of the companion candidate to be measured directly.

description: The study analyzed production, population and milk consumption in Poland against the other EU countries. After Poland's integration into the EU, production increased while the population decreased. This was due to the concentration of dairy cows and the drop in small-scale farms. Tabular, graphical, and descriptive methods were used in the analysis. In addition, a forecast was made to show that milk production and milk yield of cows will increase and cow stocking will decrease. Studies also show an increase in the milk consumption balance from 195 liters per capita in 2000 to 219 liters in 2016. / Synopsis. W pracy analizie poddano produkcję, pogłowie oraz konsumpcję mleka w Polsce na tle krajów UE. Po integracji Polski w UE produkcja uległa zwiększeniu podczas gdy pogłowie zmniejszyło się. Było to wynikiem koncentracji chowu krów mlecznych oraz wypadaniu z rynku gospodarstw o małej skali produkcji mleka. W analizie wyników badań wykorzystano metody tabelaryczne, graficzne i opisowe. Ponadto opracowano prognozę, z której wynika, że produkcja mleka i wydajność mleczna krów będą rosły, a obsada krów będzie malała. Badania dowodzą również wzrostu bilansowej konsumpcji mleka z 195 litrów na osobę w roku 2000 do 219 litrów w roku 2016.
