description: To assess acceptability, efficacy, and short- and medium-term complications of vaginal misoprostol therapy for the treatment of first trimester miscarriage. A prospective cohort study including women admitted to the Unit of Obstetrics, MBBM Foundation, San Gerardo Hospital (Monza, Italy) for medical or surgical treatment of first trimester miscarriage between October 2014 and March 2018. As per Institutional protocol, patients in the medical therapy group received 800 µg of misoprostol vaginally. A second dose could be considered 3 days after the first administration if that was ineffective. Surgical treatment consisted of uterine vacuum aspiration. Success of misoprostol treatment was defined as the expulsion of the gestational sac with no need for subsequent surgery. During the study period, 967 patients were diagnosed with first trimester miscarriage and were included in the study. Of these, 514 (53.2%) women were eligible for and consented to medical therapy. Surgical treatment was performed in the remaining 453 (46.8%) patients due to either medical contraindication to misoprostol or patient’s choice. Acceptance of misoprostol as first therapeutic choice increased over time, becoming the preferred treatment after approximately 18 months of use in clinical practice. One dose of misoprostol was successful in 69.8% (n = 359) of patients, whereas 20 women required urgent surgery for bleeding (n = 19) or suspected infection (n = 1). Among the remaining 135 patients, 20 (14.8%) refused the second dose of misoprostol and opted for surgery. Expulsion of the gestational sac was obtained in 74 additional cases who completed the medical protocol, for an overall success rate of 87.7% (433/494). The majority of women receiving misoprostol did not experience any short-term complication (92.0%) or side effect (93.8%). Eight (1.6%) cases requiring delayed surgery (hysteroscopy or vacuum aspiration) for retained product of conception were identified at the postmedical treatment follow up, thus leading to an actual success rate of misoprostol of 86.0% (n = 425). This is the first study assessing the acceptability, efficacy, and complication rate of medical management of first trimester miscarriage in an Italian tertiary care center. Our results confirm that misoprostol alone is an effective as well as a safe therapeutic option for the treatment of first trimester miscarriage.

description: A previous calculation of electroweak O(alpha) corrections to deep-inelastic neutrino scattering, as e.g. measured by NuTeV and NOMAD, is supplemented by higher-order effects. In detail, we take into account universal two-loop effects from Δαand Δρas well as higher-order final-state photon radiation off muons in the structure function approach. Moreover, we make use of the recently released O(alpha)-improved parton distributions MRST2004QED and identify the relevant QED factorization scheme, which is DIS like. As a technical byproduct, we describe slicing and subtraction techniques for an efficient calculation of a new type of real corrections that are induced by the generated photon distribution. A numerical discussion of the higher-order effects suggests that the remaining theoretical uncertainty from unknown electroweak corrections is dominated by non-universal two-loop effects and is of the order 0.0003 when translated into a shift in sin^2θ_W=1-MW^2/MZ^2. The O(alpha) corrections implicitly included in the parton distributions lead to a shift of about 0.0004.

description: In spite of some superficial success in achieving its overall global target, there has been much disillusionment with the progress on climate change since the Kyoto Protocol was negotiated in 1997. The key problems in addressing GHG emissions under the Kyoto Protocol have been the incomplete coverage across countries and lack of credibility. While significantly more onerous reduction commitments should be expected and required of developed countries in the name of economic fairness, GHG emissions must also be capped effectively in developing countries.

description: Porous magnetic silica beads are promising materials for biological and environmental applications due to their enhanced adsorption and ease of recovery. This work aims to develop a new, inexpensive and environmentally friendly approach based on agglomeration of nanoparticles in aqueous droplets. The use of an emulsion as a geometrical constraint is expected to result in the formation of spherical beads with tunable composition depending on the aqueous phase content. Magnetic silica beads are produced at room temperature by colloidal destabilization induced by addition of calcium chloride to a water-in-oil emulsion containing silica and iron oxide nanoparticles. The impact of the salt concentration, emulsification method, concentration of hydrophobic surfactant as well as silica content is presented in this paper. This method enables the production of spherical beads with diameters between 1 and 9 micrometers. The incorporation of magnetic nanoparticles inside the beads structure is confirmed using Energy Dispersive X-ray spectrometry and Scanning Transmission Electron Microscopy and results in the production of magnetic responsive beads with a preparation yield up to 84 percent. By incorporating the surfactant Span 80 in the oil phase it is possible to tune the roughness and porosity of the beads.

description: O desenvolvimento econômico, o crescimento populacional e a expansão urbana refletem no estilo de vida e nos modos de produção e consumo dos seres humanos. Como efeito desses processos, ocorre um aumento na produção de resíduos sólidos. Se eles não forem devidamente tratados, representam uma ameaça aos cidadãos, à saúde pública, ao meio ambiente e a biota terrestre. É uma questão ligada diretamente à forma como a sociedade produz e consome bens. Os problemas relacionados aos resíduos sólidos urbanos (RSU) têm se mostrado um tema relevante, em escala global, por contribuir para com o Aquecimento Global e com as Mudanças Climáticas. Os RSU são considerados uma das principais fontes de emissões dos Gases Efeito Estufa (GEE), especialmente, o Metano (CH4), devido ao processo de decomposição da matéria orgânica. Diante desta problemática, o objetivo geral desta pesquisa é estimar as emissões de CH4, produzidos no Aterro Sanitário Dom Antônio Barbosa II, situado no Município de Campo Grande/MS. Por conta dos procedimentos metodológicos empregados, foram estimadas as emissões de CH4, um total acumulado 2.132.198,57 tCO2eq. Espera que os resultados advindos desta pesquisa possam contribuir sobre os problemas relacionados ao impacto dos RSU ao meio ambiente e servir de instrumentos de tomada de decisões dos gestores públicos.

description: Current policy discussions are making a very clear connection between domestic climate policies and international trade. In this article, the economic, legal and implementation issues relating to border tax adjustments for climate policies are discussed. The overall conclusion drawn is that the connection between trade and the environment is not new, having been discussed in considerable detail since the early 1990s, and reflected in an extensive economics literature. In addition, the legal aspects of border tax adjustments are not particularly new, although only a WTO ruling on their use in the presence of domestic climate policies will resolve any legal uncertainty about their use. However, there are some new issues concerning the determination and implementation of border tax adjustments for domestic climate polices that do present additional layers of complexity.

description: Pulsar wind nebulae are a possible final stage of the circumstellar evolution of massive stars, where a fast rotating, magnetised neutron star produces a powerful wind that interacts with the supernova ejecta. The shape of these so called plerionic supernova remnants is influenced by the distribution of circumstellar matter at the time of the explosion, itself impacted by the magnetic field of the ambient medium responsible for the expansion of the circumstellar bubble of the progenitor star. To understand the effects of magnetization on the circumstellar medium and resulting pulsar nebulae, we conduct 2D magnetohydrodynamical simulations. Our models explore the impact of the interstellar medium magnetic field on the morphology of a supernova remnant and pulsar wind nebula that develop in the circumstellar medium of massive star progenitor in the warm phase of the Milky Ways interstellar medium. Our simulations reveal that the jet like structures formed on both sides perpendicularly to the equatorial plane of the pulsar, creating complex radio synthetic synchrotron emissions. This morphology is characterized by a rectangular like remnant, which is typical of the circumstellar medium of massive stars in a magnetized medium, along with the appearance of a spinning top structure within the projected rectangle. We suggest that this mechanism may be partially responsible for the complex morphologies observed in pulsar wind nebulae that do not conform to the typical torus, jet or bow shock, tail shapes observed in most cases.

description: We continue the development of a so called contextual statistical model (here context has the meaning of a complex of physical conditions). It is shown that, besides contexts producing the conventional trigonometric $\cos$-interference, there exist contexts producing the hyperbolic $\cos$-interference. Starting with the corresponding interference formula of total probability we represent such contexts by hyperbolic probabilistic amplitudes or in the abstract formalism by normalized vectors of a hyperbolic analogue of the Hilbert space. There is obtained a hyperbolic Born's rule. Incompatible observables are represented by noncommutative operators.
description: We discuss possible applications of hyperbolic quantum mechnaics (in particular, in string theory and cosmology as well as cognitive sciences); there is also given a general scheme of experimental verification of hyperbolic quantum mechanics through statistical verification of hyperbolic interference

description: Since the terrorist attacks on the United States in September 2001, an awkward nexus of security and economics has been the primary driver of North American governance. This nexus emerged as a pragmatic response to the poisonous politics of economic integration that ensued after 1994 and the advent of the North American Free Trade Agreement (NAFTA). In 2005, the three NAFTA countries launched the Security and Prosperity Partnership (SPP), aimed at reinvigorating the North American agenda to reflect the realities of security and economics. Unfortunately, the U.S. Department of Homeland Security has become the main focal point for policies affecting America’s borders as the department’s mandate has overwhelmed economic considerations and the policy approach has converged around security and law enforcement. Prospects for a new integration project will remain dim for the foreseeable future. However, the paralysis generated by the security-economics nexus has created new governance space in North America that complements the broad evolution of federal politics in all three NAFTA countries, particularly where proposals for reform of the Department of Homeland Security are concerned.

description: A lack of sufficient training data, both in terms of variety and quantity, is often the bottleneck in the development of machine learning (ML) applications in any domain. For agricultural applications, ML-based models designed to perform tasks such as autonomous plant classification will typically be coupled to just one or perhaps a few plant species. As a consequence, each crop-specific task is very likely to require its own specialized training data, and the question of how to serve this need for data now often overshadows the more routine exercise of actually training such models. To tackle this problem, we have developed an embedded robotic system to automatically generate and label large datasets of plant images for ML applications in agriculture. The system can image plants from virtually any angle, thereby ensuring a wide variety of data; and with an imaging rate of up to one image per second, it can produce lableled datasets on the scale of thousands to tens of thousands of images per day. As such, this system offers an important alternative to time- and cost-intensive methods of manual generation and labeling. Furthermore, the use of a uniform background made of blue keying fabric enables additional image processing techniques such as background replacement and plant segmentation. It also helps in the training process, essentially forcing the model to focus on the plant features and eliminating random correlations. To demonstrate the capabilities of our system, we generated a dataset of over 34,000 labeled images, with which we trained an ML-model to distinguish grasses from non-grasses in test data from a variety of sources. We now plan to generate much larger datasets of Canadian crop plants and weeds that will be made publicly available in the hope of further enabling ML applications in the agriculture sector.

description: Argues that it is unrealistic to expect the net benefit of economic globalization to be represented by a single monetary figure because its consequences are diverse and several of its consequences are uncertain. The benefits of economic globalization are accessed in terms of its possible impact on the level of global production and exchange of commodities. Both static and dynamic analysis are considered and particular attention is given to economies of scale and to technological change. Possible beneficial impacts of economic globalization on product variety are considered. The economic consequences of International mobility of factors of production (such as labour and capital) are assessed. In addition, the impacts of globalization on conditions of employment, income inequality, poverty, economic vulnerability and environmental issues of global concern are taken into account in considering the benefits and costs of globalization. While most economists seem to believe that growing economic globalization has yielded net economic benefit to date, its future ability to continue to do this is far from certain.

description: This article provides an overview of beneficial sharing mechanisms that stimulate the growth of cities and negative sharing mechanisms and spillovers which retard their growth. The economic benefits and drawbacks of a city location are considered for businesses, employees and consumers. It is suggested that the economic benefits of agglomeration arise not so much from the type of economic goods available in a city location (such as common property or local public goods) but from the enhanced operation of processes of economic exchange made possible by the growth of cities. Two theoretical implications of the growth of cities are considered: (1) the possibility that the growth of a city results in growing inequality of income and wealth within the city and (2) the likelihood that a city will grow beyond its optimal size even though the economic benefits from a city location continue to increase with its size. Despite the latter economic failure, it is argued that the growth of cities to be associated with increased levels of per capita income or well-being. It is suggested that the worldwide growth of cities is positively associated with increasing economic globalization and may be associated with the rising inequality of personal income.

description: Taking as starting point the planar model arising from the dimensional reduction of the Abelian-Higgs Carroll-Field-Jackiw model, we write down and study the extended Maxwell equations and the corresponding wave equations for the potentials. The solutions for these equations correspond to the usual ones for the MCS-Proca system, supplemented with background-dependent correction terms. In the case of a purely timelike background, exact algebraic solutions are presented which possess a similar behavior to the MCS-Proca counterparts near and far from the origin. On the other hand, for a purely spacelike background, only approximate solutions are feasible. They consist of non-trivial analytic expressions with a manifest evidence of spatial anisotropy, which is consistent with the existence of a privileged direction in space. These solutions also behave similarly to the MCS-Proca ones near and far from the origin.

This survey was intended to identify factors that led SMEs to engage in cooperative interfirm agreements; to identify the influences affecting the duration of such cooperative agreements and to determine the elements which respondents considered to be important for the long-term success of such agreements. In addition; the survey enabled the potential benefits of such agreements to be ranked. Trust was found to be an important consideration in the formation and duration of such agreements and most SMEs saw as the major benefits of such agreements the greater access this enabled them to have to markets. The implications of such cooperation for expanding the involvement of Indonesia’s garment industry in global trade are considered.

description: Cold-start is a notoriously difficult problem which can occur in recommendation systems, and arises when there is insufficient information to draw inferences for users or items. To address this challenge, a contextual bandit algorithm -- the Fast Approximate Bayesian Contextual Cold Start Learning algorithm (FAB-COST) -- is proposed, which is designed to provide improved accuracy compared to the traditionally used Laplace approximation in the logistic contextual bandit, while controlling both algorithmic complexity and computational cost. To this end, FAB-COST uses a combination of two moment projection variational methods: Expectation Propagation (EP), which performs well at the cold start, but becomes slow as the amount of data increases; and Assumed Density Filtering (ADF), which has slower growth of computational cost with data size but requires more data to obtain an acceptable level of accuracy. By switching from EP to ADF when the dataset becomes large, it is able to exploit their complementary strengths. The empirical justification for FAB-COST is presented, and systematically compared to other approaches on simulated data. In a benchmark against the Laplace approximation on real data consisting of over $670,000$ impressions from autotrader.co.uk, FAB-COST demonstrates at one point increase of over $16\%$ in user clicks. On the basis of these results, it is argued that FAB-COST is likely to be an attractive approach to cold-start recommendation systems in a variety of contexts.
Absence of complement receptor 3 results in reduced binding and ingestion of Mycobacterium tuberculosis but has no significant effect on the induction of reactive oxygen and nitrogen intermediates or on the survival of the bacteria in resident and interferon-gamma activated macrophages
Creators: name: Rooyakkers, Amanda Wilhelmina Johanna
Publisher: name: University of British Columbia

description: The interaction of host macrophage (MΦ) and Mycobacterium tuberculosis (Mtb) is mediated by cell surface receptors and is important in establishing intracellular infection. MΦs are part of the mammalian defenses against microbial infection and can kill invading organisms via reactive oxygen intermediates (ROI) and reactive nitrogen intermediates (RNI). Using a Complement Receptor 3 (CR3) knockout mouse model I have examined whether the presence of CR3 affected the binding and uptake of Mtb by resident and activated MΦ, the survival of the ingested bacteria and the induction of ROI and RNI during this interaction. I have shown that, although CR3 plays a definitive role in the uptake of Mtb, the receptor played no role in the subsequent survival of the bacteria. The finding held true for resident MΦs in the absence and presence of serum opsonins and also in Interferon-gamma (IFN-γ) activated MΦs. Activation of MΦpopulations with IFN- γ significantly inhibited the growth of Mtb in host MΦs and enhanced the respiratory burst and production of nitric oxide (NO). However, the presence of CR3 was not found to be critical in any of these mechanisms. Furthermore, I demonstrated that the control of intracellular growth of Mtb in IFN- γ activated MΦs was not mediated by a direct effect of NO.

description: According to The Macquarie Dictionary, the word ‘trust’ has more than 20 interpretations in English. Therefore, it is important to specify the way in which the word is being used in any discourses about managerial and economic issues. In what respect and to what extent are economic agents to be trusted in their dealings with others. When economic agents are untrustworthy, this adds to economic transaction costs, reduces the level of economic activity and the achievable level of economic welfare as well as potential gains from growing globalisation. Several adverse economic consequences of lack of business trust are explored along with their consequences for the process of globalisation. Business co-operation and alliances can be important for gaining access to international markets, particularly for small and medium-sized firms. Middle traders can play an important role through their cooperation with smaller producers in enabling their products to be exported. However, suppliers at the bottom of the exchange chain tend to become locked into such cooperative arrangements. This can result in their economic exploitation and growing mistrust of such arrangements. Furthermore, once exploitation by a few middlemen occurs, competitors may be forced to follow their practice. Hence, the bad middlemen drive out the good and cooperative institutional arrangements can be expected to collapse with adverse impacts on economic activity, welfare and exports. Trust is also important in relation to most contracts and the sale of goods. As pointed out by Williamson, most contracts are incomplete and rely for their full execution on some degree of trust or unspecified expectations. There ‘reasonable’ expectations may vary from country to country and this creates a challenge for global transactions. Furthermore, trust problems are important in relation to principal-agent contracts which are invariably incomplete. Global operations of businesses can provide extra scope for agents to engage in deviant behaviour. Sale of goods can also involve distrust. Scope for fraud and misrepresentation of goods can increase when there is considerable distance between the traders as is often the case in global exchanges. This limits the incentive for trade and can result in market failure and a loss of economic welfare. It reduces the potential extent of and benefits from economic globalisation. Measures that can or have been adopted to reduce these problems are outlined

description: This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy sector, we show that the combination between environmental and knowledge externalities provides a strong rationale for implementing a portfolio of policies for both emissions reduction and the internalisation of knowledge externalities. Moreover, we show that implementing technology policy as a substitute for stabilisation policy is likely to increase global emissions.

description: We investigate the effectiveness of the TRIPS Agreement in triggering changes to countries' intellectual property rights (IPR) protection regimes in the empirical panel model that utilizes a range of aggregation strategies. The effects of the TRIPS agreement on the IPR protection vary across levels of development and geography. Developed countries where IPR protection regimes closely resembled TRIPS Agreement obligations before implementation, were not significantly affected. Developing countries significantly responded to the TRIPS Agreement by tightening IPR protection regimes. The empirical evidence suggests that the TRIPS Agreement has been successful in coercing WTO member countries to strengthen domestic protection of IPR.

description: Space-based gravitational-wave (GW) detectors, including LISA, Taiji and TianQin, are able to detect mHz GW signals produced by mergers of supermassive black hole binaries, which opens a new window for GW astronomy. In this article, we numerically estimate the potential capabilities of the future networks of multiple space-based detectors using Bayesian analysis. We modify the public package Bilby and employ the sampler PyMultiNest to analyze the simulated data of the space-based detector networks, and investigate their abilities for source localization and testing the parity symmetry of gravity. In comparison with the case of an individual detector, we find detector networks can significantly improve the source localization. While for constraining the parity symmetry of gravity, we find that detector networks and an individual detector follow the similar constraints on the parity-violating energy scale $M_{\rm PV}$. Similar analysis can be applied to other potential observations of various space-based GW detectors.

description: Net farm income for most representative farms in 2019 is projected to be lower than in 2009. Low-profit farms, which comprise 20% of the farms in the study, may not have financial resiliency to survive without off-farm income. Commodity prices are expected to increase slowly from current levels. Commodity yields are projected to increase at historical trend-line rates and production expenses are expected to return to normal growth rates. Debt-to-asset ratios for all farms except for the low profit farm will decrease slightly throughout the forecast period. Debt-to-asset ratios for the low-profit farms are expected to increase to about 0.70.

description: The optical and electronic properties of crystalline Li2TeO3, which is a tellurite glass, is studied in the framework of density functional theory (DFT) implemented software SIESTA. The material has monoclinic symmetrized structure and the unit or primitive cell of the material, periodic in all directions has been taken to study the properties. The electronic structures show that it is a wide-gap semiconductor and the property changes to metallic when subjected to electric field. This tunable property can be used in various fields of electronics. The optical properties studied tells that Li2TeO3 can be a promising material to be used as a hole transport material (HTM) for developing efficient perovskite solar cell including other applications as well.

description: This paper explores the idea that within the framework of three-dimensional quantum gravity one can extend the notion of Feynman diagram to include the coupling of the particles in the diagram with quantum gravity. The paper concentrates on the non-trivial part of the gravitational response, which is to the large momenta propagating around a closed loop. By taking a limiting case one can give a simple geometric description of this gravitational response. This is calculated in detail for the example of a closed Feynman loop in the form of a trefoil knot. The results show that when the magnitude of the momentum passes a certain threshold value, non-trivial gravitational configurations of the knot play an important role. The calculations also provide some new information about a limit of the coloured Jones polynomial which may be of independent mathematical interest.

description: Neste paper foram desenvolvidas placas de isolamento termo-acústico utilizando um resíduo da indústria alimentícia, a fibra da casca de coco, juntamente com um aglutinante. Foram selecionadas três resinas para efetuar a conformação junto à fibra de coco: breu, éster de breu e resina hidrocarbônica. Foram efetuadas doze composições com diferentes proporções de resina, para determinar a melhor relação resina/fibra. Foram realizados cinco ensaios distintos para determinação do compósito que melhor cumpre a função à qual o projeto está sendo proposto: ensaio de condutividade térmica, absorção de água, análise microscópica, isolamento sonoro e determinação do isolamento ao ruído aéreo. Através destes ensaios, constatou-se que o compósito que possui 40% de éster de breu na composição, apresentou melhores resultados entre os demais. Houve a absorção de 4,3% de água após o período de 2 horas e 9% após 24 horas. Na análise microscópica foi possível comprovar que a resina inibe a passagem de água por entre as ramificações; através do ensaio de condutividade térmica do material. Determinou-se o índice de 0,05498 W/m*K para a chapa contendo éster de breu; no ensaio de isolamento sonoro, ocorreu a redução de aproximadamente 28 decibéis quando comparada à caixa sem isolante. No ensaio para determinação do isolamento ao ruído aéreo, obteve-se o índice de redução sonora ponderado Rw (dB): 47. O compósito apresenta bons resultados gerando possibilidades de ser aplicado como isolante termoacústico.

description: We describe generalizations of the Pauli group, the Clifford group and stabilizer states for qudits in a Hilbert space of arbitrary dimension d. We examine a link with modular arithmetic, which yields an efficient way of representing the Pauli group and the Clifford group with matrices over the integers modulo d. We further show how a Clifford operation can be efficiently decomposed into one and two-qudit operations. We also focus in detail on standard basis expansions of stabilizer states.
