In this paper we aim to outline the contribution of parallel and comparable corpora to translation. Nevertheless, corpora are not a new or unknown method to translators. Besides translated texts, there is a long tradition of using “parallel” texts, meaning similar texts, in the same domain or register as the text-source. In this paper though, in accordance with modern bibliography, we consider as a parallel corpus a collection of texts in language A and their translation in language B, while comparable corpora are collections of texts of two languages or more, constructed on the basis of certain criteria (text size, subject, time period, etc.). Moreover, we focus on the creation of parallel and comparable corpora in the domain of the Stock Market and we describe the electronic tools used for their construction. The creation of a glossary of 1,908 Stock Market terms and frequency lists of simple and multi-word terms, which could be used by translators in order to deal with terminology .

Subjects: Urban mobility; sustainability; global warming

description: El modelo energético en las sociedades industrializadas, basado en un elevado consumo de combustibles fósiles, está provocando la aceleración del calentamiento global en el planeta. Al mismo tiempo, las reservas mundiales de energías fósiles comienzan a mostrar síntomas de agotamiento. Por tanto, resulta imprescindible repensar este insostenible modelo energético. Durante este siglo XXI será necesario diseñar sociedades que demanden menos energía, y emitan menores cantidades de carbono a la atmósfera. Para lograr esta meta habrá que comenzar por modelar los estilos de vida de la población occidental, que actualmente causan una gran huella ecológica sobre el entorno natural. Afinando un poco más, cabe destacar la relevancia que tendrá un posible cambio en los hábitos de transporte de la ciudadanía, pues este sector representa por sí sólo un elevado porcentaje respecto al consumo total de energía, y es además uno de los grandes responsables de emisiones de CO2. Los teóricos Manuel Castells y Jordi Borja otorgan a los gobiernos locales el papel de protagonista para afrontar los grandes retos globales en el escenario del siglo XXI. El ámbito local resulta idóneo para implementar acciones concretas de carácter trasversal que, finalmente, tendrán una repercusión sobre las problemáticas globales. Por tanto, el presente trabajo de investigación pretende hallar una estrategia comunicativa eficaz dentro del ámbito local para propiciar un cambio en los hábitos de movilidad de la población, con la finalidad última de impulsar ciudades sostenibles y comprometidas tanto con el medio ambiente, como con la integridad de la sociedad para el siglo XXI. Finalmente, las herramientas utilizadas para desarrollar este proyecto de investigación fueron: analizar el documento denominado Plan de Movilidad Urbana Sostenible (PMUS) del ayuntamiento de Segovia; y por el otro lado, decidí aplicar entrevistas en profundidad con expertos y agentes sociales de Segovia, es decir, metodología cualitativa.

description: This study examines the effects of weather shock on households’ decision to engage in different types of off-farm work in rural Ethiopia. A multinomial logit model is applied to household data collected in 1999 and 2004. The regression results show that the level and variability of rainfall has a significant effect on the decision by households to engage in any type of off-farm work. The probability of a household deciding to participate in low-return, off-farm activities increases with lower levels and higher variability of rainfall, suggesting that households engage in those activities as a strategy for coping with adverse weather shock. Contrary to this, we find that participation in high-return activities increases with the level of rainfall and tends to decrease with rainfall variability, suggesting a strong correlation between off-farm activities and agricultural production.

description: This is a survey of the author's series of three papers math.DG/0111324, math.DG/0111326, math.DG/0204343 using analysis to investigate special Lagrangian 3-folds (SL 3-folds) in C^3 invariant under the U(1)-action (z_1,z_2,z_3) --> (gz_1,g^{-1}z_2,z_3) for unit complex numbers g, and their sequel math.DG/0011179 on special Lagrangian fibrations and the SYZ Conjecture. We briefly present the main results of these four long papers, giving some explanation and motivation, but no proofs. The aim is to make the results and ideas accessible to String Theorists and others who have an interest in special Lagrangian 3-folds and fibrations, but have no desire to read pages of technical analysis. Let N be an SL 3-fold in C^3 invariant under the U(1)-action above. Then |z_1|^2-|z_2|^2=2a on N for some real number a. Locally, N can be written as a kind of graph of functions u,v : R^2 --> R satisfying a nonlinear Cauchy-Riemann equation depending on a, so that u+iv is like a holomorphic function of x+iy. When a=0 the equations may have singular points where u,v are not differentiable, which leads to analytic difficulties. We prove existence and uniqueness results for solutions u,v on domains S in R^2 with boundary conditions, including singular solutions. We study their singularities, giving a rough classification by multiplicity and type. We prove the existence of large families of fibrations of open subsets of C^3 by U(1)-invariant SL 3-folds, including singular fibres. Finally, we use these fibrations as local models to draw conclusions about the SYZ Conjecture on Mirror Symmetry of Calabi-Yau 3-folds.

description: Autonomous Vehicles (AVs) are increasingly embraced around the world to advance smart mobility and more broadly, smart, and sustainable cities. Algorithms form the basis of decision-making in AVs, allowing them to perform driving tasks autonomously, efficiently, and more safely than human drivers and offering various economic, social, and environmental benefits. However, algorithmic decision-making in AVs can also introduce new issues that create new safety risks and perpetuate discrimination. We identify bias, ethics, and perverse incentives as key ethical issues in the AV algorithms' decision-making that can create new safety risks and discriminatory outcomes. Technical issues in the AVs' perception, decision-making and control algorithms, limitations of existing AV testing and verification methods, and cybersecurity vulnerabilities can also undermine the performance of the AV system. This article investigates the ethical and technical concerns surrounding algorithmic decision-making in AVs by exploring how driving decisions can perpetuate discrimination and create new safety risks for the public. We discuss steps taken to address these issues, highlight the existing research gaps and the need to mitigate these issues through the design of AV's algorithms and of policies and regulations to fully realise AVs' benefits for smart and sustainable cities.

description: A brief review is given of the recent solution of a non-compact CFT describing a NS-supported pp-wave background. We will first explain how to compute the three and four-point correlators using current algebra techniques, thereby showing that some generic features of the non-compact WZW models become very clear in this simple context. We will then present the Penrose limit as a contraction of an U(1)xSU(2)_k WZW model, an approach that could prove useful in order to understand holography for pp-wave space-times. We will finally comment on the string amplitudes and on the existence of two flat space limits.

description: Droughts in Syria have occurred during almost every second year over the past half century, and may become even more frequent in the future. This paper assesses the economic and social implications of droughts using a dynamic computable general equilibrium model for Syria. Results show that growth in economic output (GDP)during drought years can be close to one percentage point lower compared to nondrought years. Food security and the poor are hard hit by droughts, mainly through the loss of capital, incomes and higher food/feed prices. Poverty levels increase by about 0.3 to 1.2 percentage points during an average drought and stay above “non-drought levels” even when the drought is over. Poor farm households are hardest hit, followed by rural nonfarm and urban households. Actions for improving the resilience of the poor should focus on agriculture, non-farm employment opportunities and social safety nets.
Improving the convergence of defect calculations in supercells - an ab initio study of the neutral silicon vacancy

description: We present a systematic methodology for the accurate calculation of defect structures in supercells which we illustrate with a study of the neutral vacancy in silicon. This is a prototypical defect which has been studied extensively using ab initio methods, yet remarkably there is still no consensus about the energy or structure of this defect, or even whether the nearest neighbour atoms relax inwards or outwards. In this paper we show that the differences between previous calculations can be attributed to supercell convergence errors, and we demonstrate how to systematically reduce each such source of error. The various sources of scatter in previous theoretical studies are discussed and a new effect, that of supercell symmetry, is identified. It is shown that a consistent treatment of this effect is crucial to understanding the systematic effects of increasing the supercell size. This work therefore also presents the best converged ab initio study of the neutral silicon vacancy to date.

description: Recent work highlights that tens of Galactic double neutron stars are likely to be detectable in the millihertz band of the space-based gravitational-wave observatory, LISA. Kyutoku and Nishino point out that some of these binaries might be detectable as radio pulsars using the Square Kilometer Array (SKA). We point out that the joint LISA+SKA detection of a $f_\text{gw}\gtrsim$1 mHz binary, corresponding to a binary period of $\lesssim$400 s, would enable precision measurements of ultra-relativistic phenomena. We show that, given plausible assumptions, multi-messenger observations of ultra-relativistic binaries can be used to constrain the neutron star equation of state with remarkable fidelity. It may be possible to measure the mass-radius relation with a precision of $\approx$0.2% after 10 yr of observations with the SKA. Such a measurement would be roughly an order of magnitude more precise than possible with other proposed observations. We summarize some of the other remarkable science made possible with multi-messenger observations of millihertz binaries, and discuss the prospects for the detection of such objects.

description: The quasinormal modes of the Reissner-Nordström de Sitter black hole for the massless Dirac fields are studied using the Pöshl-Teller potential approximation. We find that the magnitude of the imaginary part of the quasinormal frequencies decreases as the cosmological constant or the orbital angular momentum increases, but it increases as the charge or the overtone number increases. An interesting feature is that the imaginary part is almost linearly related to the real part as the cosmological constant changes for fixed charge, and the linearity becomes better as the orbital angular momentum increases. We also prove exactly that the Dirac quasinormal frequencies are the same for opposite chirality.

description: We develop an alternative derivation of the renormalized expression for the one-loop soliton quantum mass corrections in (1+1)-dimensional scalar field theories. We regularize implicitly such quantity by subtracting and adding its corresponding tadpole graph contribution and use the renormalization prescription that such added term vanishes with adequate counterterms. As a result, we get a finite unambiguous formula for the soliton quantum mass corrections up to one-loop order, which turns to be independent of the chosen regularization scheme.

description: Push-pull technology (PPT) is currently and widely promoted as a control measure for stemborers, Striga weed and soil fertility improvement in maize fields in western Kenya in order to improve on cereal production. Since it is a new and relatively knowledge-intensive technology, access information about its efficacy is critical for maximum adoption and continued use. Given that different technologies may need different pathways for adoption, this study sought to identify the most effective dissemination pathway(s) for scaling up the technology among many farmers. A two limit Tobit regression was used to analyze data from 491 respondents randomly selected from four districts in western Kenya. The results indicated that chronologically field days (FD), farmer field schools (FFS) and farmer teachers (FT), had the greatest impact on the probability that a farmer in the study area would adopt PPT and at enhanced intensity of adoption. Efforts to disseminate PPT should therefore target the use of demonstrations through field days to intensify adoption. FT and FFS where appropriate can be used as alternative pathways to reinforce extension messages.

description: The purpose of the work was to determine whether and how city halls in Poland use Twitter. An attempt to identify the information that is sent through tweets. For this purpose, the Twitter profiles of city hall councils were identified. Tweets' URLs and their content were acquired. The text mining analysis of the tweets were performed. It included text pre-processing, creation of corpora of the documents, creation of a document-term matrix, and application of classical methods deriving from data mining. Due to the number of cities, no requests to city halls concerning their Twitter profiles were sent. Profiles on Twitter were identified using the Google search engine. Only the content of the tweets and the time they were sent were analyzed. The conducted research allowed to establish the number of users (cities hall) and the number of tweets published by them, the most frequently used hashtags, the number of tweets published per hour and day of the week, the number of hashtags, users mentioned, and links in tweets. Hidden, abstract topics describing tweets were generated with the LDA algorithm. The study found that text mining of tweet content helps determine which groups of information are provided by city halls. It was also determined whether they included links to external sources or hashtags in their tweets and whether they mentioned other users.

description: The concept of transfer of learning is a field that starts to be of interest to those who are involved with the teaching of translation. It concerns a complex mental process that allows the translator to handle new situations looking for structural analogies between the present problems required to be managed and respective situations that have been managed successfully in the past. The transfer of learning takes place sometimes consciously and sometimes unconsciously. Generally, beginners in translation are acting consciously and experienced translators unconsciously. This is because with repetition and attrition cognitive processes are automated. This phenomenon is called proceduralisation. In our opinion the concept of transfer of learning should be at the core of the design of both the curriculum and all courses offered. Among the objectives to be set by the teacher should be to include reference about the concept of transfer of learning. This reference could be accompanied by exercises in which students are asked to pursue the application of transfer techniques and others of correcting translations, in which the teacher will identify cases of positive and negative transfer of learning.

Classification of multipartite entangled states by multidimensional determinants

description: We find that multidimensional determinants "hyperdeterminants", related to entanglement measures (the so-called concurrence or 3-tangle for the 2 or 3 qubits, respectively), are derived from a duality between entangled states and separable states. By means of the hyperdeterminant and its singularities, the single copy of multipartite pure entangled states is classified into an onion structure of every closed subset, similar to that by the local rank in the bipartite case. This reveals how inequivalent multipartite entangled classes are partially ordered under local actions. In particular, the generic entangled class of the maximal dimension, distinguished as the nonzero hyperdeterminant, does not include the maximally entangled states in Bell's inequalities in general (e.g., in the $n \geq 4$ qubits), contrary to the widely known bipartite or 3-qubit cases. It suggests that not only are they never locally interconvertible with the majority of multipartite entangled states, but they would have no grounds for the canonical n-partite entangled states. Our classification is also useful for the mixed states.

description: Discrete time crystals (DTCs) are new phases of matter characterized by the presence of an observable evolving with $nT$ periodicity under a $T$-periodic Hamiltonian, where $n>1$ is an integer insensitive to small parameter variations. In particular, DTCs with $n=2$ have been extensively studied in periodically quenched and kicked spin systems in recent years. In this paper, we study the emergence of DTCs from the many-body quantum chaos perspective, using a rather simple model depicting a harmonically driven spin chain. We advocate to first employ a semiclassical approximation to arrive at a mean-field Hamiltonian and then identify the parameter regime at which DTCs exist, with standard tools borrowed from studies of classical chaos. Specifically, we seek symmetric-breaking solutions by examining the stable islands on the Poincare surface of section of the mean-field Hamiltonian. We then turn to the actual many-body quantum system, evaluate the stroboscopic dynamics of the total magnetization in the full quantum limit, and verify the existence of DTCs. Our effective and straightforward approach indicates that in general DTCs are one natural aspect of many-body quantum chaos with mixed classical phase space structure. Our approach can also be applied to general time-periodic systems, which is thus promising for finding DTCs with $n>2$ and opening possibilities for exploring DTCs properties beyond their time-translational breaking features.

description: A random walk is performed over a disordered media composed of $N$ sites random and uniformly distributed inside a $d$-dimensional hypercube. The walker cannot remain in the same site and hops to one of its $n$ neighboring sites with a transition probability that depends on the distance $D$ between sites according to a cost function $E(D)$. The stochasticity level is parametrized by a formal temperature $T$. In the case $T = 0$, the walk is deterministic and ergodicity is broken: the phase space is divided in a ${\cal O}(N)$ number of attractor basins of two-cycles that trap the walker. For $d = 1$, analytic results indicate the existence of a glass transition at $T_1 = 1/2$ as $N \to \infty$. Below $T_1$, the average trapping time in two-cycles diverges and out-of-equilibrium behavior appears. Similar glass transitions occur in higher dimensions choosing a proper cost function. We also present some results for the statistics of distances for Poisson spatial point processes.

Year: 2025

Industrialized diets – high in processed foods and low in fibre – disrupt the gut microbiome and predispose us to chronic diseases, such as obesity, diabetes, and heart disease, that are endemic in the twenty-first century.

Microbiome scientists Anissa Armet (PhD in Nutrition and Metabolism, and registered dietitian) and Jens Walter (Professor and Doctorate in Microbiology) have developed the Non-Industrialized Microbiome Restore diet, or NiMe diet (pronounced Nee-Mee), to restore key microbiome features affected by industrialization and promote cardiometabolic health. In this book, the authors present the scientific rationale for developing the NiMe diet, information on how the diet was clinically validated in a human trial, as well as the recipes used in the trial.
Canonical normalisation and Yukawa matrices

description: We highlight the important role that canonical normalisation of kinetic terms in flavour models based on family symmetries can play in determining the Yukawa matrices. Even though the kinetic terms may be correctly canonically normalised to begin with, they will inevitably be driven into a non-canonical form by a similar operator expansion to that which determines the Yukawa operators. Therefore in models based on family symmetry canonical re-normalisation is mandatory before the physical Yukawa matrices can be extracted. In nearly all examples in the literature this is not done. As an example we perform an explicit calculation of such mixing associated with canonical normalisation of the Kahler metric in a supersymmetric model based on SU(3) family symmetry, where we show that such effects can significantly change the form of the Yukawa matrix. In principle quark mixing could originate entirely from canonical normalisation, with only diagonal Yukawa couplings before canonical normalisation.

description: We study both the CP-even and CP-odd effective chiral Lagrangians of next minimal composite Higgs model {with symmetry breaking pattern depicted by the coset $SO(6)/SO(5)$} through the sigma/omega decomposition, in which the Goldstone matrix of the coset is decomposed in terms of the standard model Higgs doublet and an additional scalar singlet $s$ at the electroweak scale. The effective Lagrangian is described by the electroweak chiral Lagrangian up to $p^4$ order, with a function dependence on the Higgs boson and new scalar $s$, named Higgs function. This function in the effective Lagrangian incorporates the Higgs non-linearity or vacuum misalignment effects in the next minimal composite Higgs model, due to the Riemann curvature on the Nambu-Goldstone bosons scalar manifold, leads to various Higgs couplings deviated from the standard model ones, and also indicates the relations among different Higgs couplings in the low energy. Matching to the Higgs effective field theory below the electroweak scale, we obtain various low energy observables such as the electroweak oblique parameters, anomalous triple and quartic gauge couplings, anomalous couplings of Higgs to gauge bosons, in which the Higgs non-linearity effects are encoded in the ratio $ξ\equiv v^2/f^2$ of the electroweak scale and the new physics scale.

description: The chemical components and mechanisms underlying the toxicity and adverse health effects of particulate matter (PM) in the atmosphere have not been fully elucidated. After designing a small, openable, stainless steel cyclone to collect PM samples effectively in powder form for use in toxicological experiments, we evaluated its performance. We compared it with a commercially available aluminum cyclone of similar dimensions, but which is unopenable. The aerodynamic cutoff diameter of the openable cyclone was found by experimentation to be approximately 0.2 µm at a flow rate of 90 L min−1, which is comparable to the unopenable commercial cyclone. The sampling yields, representing the fraction of obtained sample mass relative to the total mass of PM with aerodynamic diameter smaller than 2.5 μm (PM2.5) drawn into the sampler, were approximately 1.3 times higher, on average, for the openable cyclone than for the unopenable cyclone. The openable design of the cyclone might contribute to a marked increase in the finally obtained amounts of PM samples. Analyses of metal concentrations in the PM samples collected simultaneously using the stainless steel openable cyclone and aluminum unopenable cyclone suggest that the stainless steel cyclone is less likely than the aluminum cyclone to cause sample contamination from its material. The openable cyclone developed for this study facilitates the effective collection of powder-form PM samples suitable for use in toxicological experiments.

description: The notion of a tensor product with projections or with inclusions is defined. It is shown that the definition of stochastic independence relies on such a structure and that independence can be defined in an arbitrary category with a tensor product with inclusions or projections. In this context, the classifications of quantum stochastic independence by Muraki, Ben Ghorbal, and Schürmann become classifications of the tensor products with inclusions for the categories of algebraic probability spaces and non-unital algebraic probability spaces. The notion of a reduction of one independence to another is also introduced. As examples the reductions of Fermi independence and boolean, monotone, and anti-monotone independence to tensor independence are presented.

description: In order to split the influence of the orbital and spin effects on the inplane magnetoresistance of a quasi two-dimensional gas we derive its linear response function and dielectric function for the case of anisotropic effective mass. This result is used for the calculation of elastic transport relaxation time of a quasi two dimensional system in a parallel magnetic field. The relaxation time is proved to be isotropic in the low density limit for the case of charged impurity scattering, allowing to separate the two contributions.

description: Machine Translation (MT) evaluation is a hard task considering the difficulties that raise from the translation process itself. In this paper we present the results of the evaluation of a Statistical Machine Translation (SMT) system in which the Moses decoder was trained for the language pair Greek-Italian. The evaluation task was both automatic and non–automatic (human). For the automatic evaluation, the metrics BLEU, NIST were used, while for the human evaluation, the adequacy and the ﬂuency of the translated texts was evaluated. A corpus of 120 individual sentences were evaluated, (e.g. EU texts, scientific & technical texts, subtitles, proverbs etc.), by postgraduate students of the direction of Translation, Interpretation and Communication of the Department of Italian Language and Literature of the Aristotle University of Thessaloniki. The first results show that SMT performs well when translating text of this type

description: E-cigarette aerosols contain a complex mixture of harmful and potentially harmful chemicals. Once released into the environment, they evolve and become new sources of indoor air pollutants that could pose a significant threat to both users and non-users. However, current understanding of the physicochemical properties of e-cigarette aerosol constituents that govern gas-particle partitioning in the atmosphere is limited, making it difficult to estimate the health risks associated with exposure. Here, we used correlation gas chromatography (C-GC) and two-dimensional volatility basis set (2D-VBS) methods to determine the vapor pressures and volatility for commonly reported toxic and irritating e-cigarette aerosol constituents. The vapor pressures of target compounds at 298 K were estimated from the Antoine-type linear relationship between the vapor pressure of reference standards and their retention times. Our C-GC results showed an overall positive correlation (R = 0.84) with estimates using the EPI (Estimation Programs Interface) Suite. The volatility calculated by 2D-VBS correlates well with the calculated vapor pressure from both C-GC (R = 0.82) and EPI Suite (R = 0.85). The volatility distribution also indicated fresh e-cigarette aerosol constituents are mainly more volatile organic compounds. Our case study revealed that low-vapor-pressure compounds (e.g., σ-dodecalactone, γ-decalactone, and maltol) become enriched in the e-cigarette aerosols within 2 h following vaping emissions. Overall, these findings demonstrate the applicability of the C-GC and 2D-VBS methods for determining the physiochemical properties of e-cigarette aerosol constituents, which can aid in assessing the dynamic chemical composition of e-cigarette aerosols and exposures to vaping emissions in indoor environments.

description: Massive stars and their stellar winds are important for a number of feedback processes. The mass lost in the stellar wind can help determine the end-point of the star as a NS or a BH. However, the impact of mass-loss on the post-Main Sequence evolutionary stage of massive stars is not well understood. Westerlund 1 is an ideal astrophysical laboratory in which to study massive stars and their winds in great detail over a large range of different evolutionary phases. Aims: We aim to study the radio emission from Westerlund 1, in order to measure radio fluxes from the population of massive stars, and determine mass-loss rates and spectral indices where possible. Methods: Observations were carried out in 2015 and 2016 with the Australia telescope compact array (ATCA) at 5.5 and 9 GHz using multiple configurations, with maximum baselines ranging from 750m to 6km. Results: 30 stars were detected in the radio from the fully concatenated dataset, 10 of which were WRs (predominantly late type WN stars), 5 YHGs, 4 RSGs, 1 LBV star, the sgB[e] star W9, and several O and B supergiants. New source detections in the radio were found for 5 WR stars, and 5 OB supergiants. These detections have led to evidence for 3 new OB supergiant binary candidates, inferred from derived spectral index limits. Conclusions: Spectral indices and index limits were determined for massive stars in Westerlund 1. For cluster members found to have partially optically thick emission, mass-loss rates were calculated. Under the approximation of a thermally emitting stellar wind and a steady mass-loss rate, clumping ratios were then estimated for 8 WRs. Diffuse radio emission was detected throughout the cluster. Detections of knots of radio emission with no known stellar counterparts indicate the highly clumped structure of this intra-cluster medium, likely shaped by a dense cluster wind.
