description: In recent years, contour-based eigensolvers have emerged as a standard approach for the solution of large and sparse eigenvalue problems. Building upon recent performance improvements through non-linear least square optimization of so-called rational filters, we introduce a systematic method to design these filters by minimizing the worst-case convergence ratio and eliminate the parametric dependence on weight functions. Further, we provide an efficient way to deal with the box-constraints which play a central role for the use of iterative linear solvers in contour-based eigensolvers. Indeed, these parameter-free filters consistently minimize the number of iterations and the number of FLOPs to reach convergence in the eigensolver. As a byproduct, our rational filters allow for a simple solution to load balancing when the solution of an interior eigenproblem is approached by the slicing of the sought after spectral interval.

description: Rice is of key importance to Indonesia's national and household level food security. The choice of tariff policy has important implications for consumers and producers with policy makers having to decide between the trade-offs implied for the various stakeholders. In this study we use a multi-market model to assess the impact of hypothetical rice tariff changes on household welfare and other variables of interest to rice policy-makers. A reduction in the rice tariff from 30 to 0% reduces rice supply and wheat demand and stimulates rice demand and soybean supply. Rice imports increase from 0.8 to 2 million tons. Rural households except for the Java-top income group, see incomes fall. In terms of purchasing power all households gain very significantly. Eliminating rice tariffs increases crop diversification and more so in those areas and for those income groups which started off least diversified. It is clear that the higher retail rice price resulting from a 30% ad-valorem tariff rate imposes significant cost on the 90% of Indonesian households, including most of the very poor households, who are net rice buyers. The implied income gains appear relatively modest but do accrue to middle and poorer households especially in Java. On the other hand an increase in the tariff from 30 to 50% eliminates rice imports, reduces soybean output and stimulates wheat demand. Rural households, except for the Java-top income group, see incomes rise although the effect is relatively modest. In terms of purchasing power households are all worse off.

description: Road surface friction significantly impacts traffic safety and mobility. A precise road surface friction prediction model can help to alleviate the influence of inclement road conditions on traffic safety, Level of Service, traffic mobility, fuel efficiency, and sustained economic productivity. Most related previous studies are laboratory-based methods that are difficult for practical implementation. Moreover, in other data-driven methods, the demonstrated time-series features of road surface conditions have not been considered. This study employed a Long-Short Term Memory (LSTM) neural network to develop a data-driven road surface friction prediction model based on historical data. The proposed prediction model outperformed the other baseline models in terms of the lowest value of predictive performance measurements. The influence of the number of time-lags and the predicting time interval on predictive accuracy was analyzed. In addition, the influence of adding road surface water thickness, road surface temperature and air temperature on predictive accuracy also were investigated. The findings of this study can support road maintenance strategy development and decision making, thus mitigating the impact of inclement road conditions on traffic mobility and safety. Future work includes a modified LSTM-based prediction model development by accommodating flexible time intervals between time-lags.

description: The major histocompatibility complex (MHC) is a core part of the adaptive immune system. As in other vertebrate taxa, it may also affect human chemical communication via odour-based mate preferences, with greater attraction towards MHC-dissimilar partners. However, despite some well-known findings, the available evidence is equivocal and made complicated by varied approaches to quantifying human mate choice. To address this, we here conduct comprehensive meta-analyses focusing on studies assessing: (i) genomic mate selection, (ii) relationship satisfaction, (iii) odour preference, and (iv) all studies combined. Analysis of genomic studies reveals no association between MHC-dissimilarity and mate choice in actual couples; however, MHC effects appear to be independent of the genomic background. The effect of MHC-dissimilarity on relationship satisfaction was not significant, and we found evidence for publication bias in studies on this area. There was also no significant association between MHC-dissimilarity and odour preferences. Finally, combining effect sizes from all genomic, relationship satisfaction, odour preference and previous mate choice studies into an overall estimate showed no overall significant effect of MHC-similarity on human mate selection. Based on these findings, we make a set of recommendations for future studies, focusing both on aspects that should be implemented immediately and those that lurk on the far horizon. We need larger samples with greater geographical and cultural diversity that control for genome-wide similarity. We also need more focus on mechanisms of MHC-associated odour preferences and on MHC-associated pregnancy loss.This article is part of the Theo Murphy meeting issue ‘Chemical communication in humans’.

description: The migration of labor out of rural areas and the flow of remittances from migrants torural households is an increasingly important feature of less developed countries. Thispaper explores ways in which migration influences incomes and productivity of land andhuman capital in rural households over time, using new household survey data fromMexico. Our findings suggest that a massive increase in migration to the United Statesincreased per-capita incomes via remittances and also by raising land productivity inmigrant-sending households. They do not support the pessimistic view that migrationdiscourages production in migrant-sending economies, nor the view implicit in separableagricultural household models that migration and remittances influence householdincomes but not production.

description: We demonstrate both theoretically and experimentally two limiting factors in cooling electrons using biased tunnel junctions to extract heat from a normal metal into a superconductor. Firstly, when the injection rate of electrons exceeds the internal relaxation rate in the metal to be cooled, the electrons do no more obey the Fermi-Dirac distribution, and the concept of temperature cannot be applied as such. Secondly, at low bath temperatures, states within the gap induce anomalous heating and yield a theoretical limit of the achievable minimum temperature.

description: Electro-optic time lenses are promising experimental components for photonic spectral-temporal processing of quantum information. We report a stable method to realize an electro-optic time lens, which relies on the amplification of an electronic response of a fast photodiode. The method does not require a repetitive clock and may be applied to aperiodic optical signals. We experimentally demonstrate the approach using single-photon pulses and directly verify its aperiodicity. The approach will enable construction of complex electro-optic temporal optical systems.

description: We discuss dissipative stochastic wave and diffusion equations resulting from an interaction of the inflaton with an environment in an external expanding metric. We show that a diffusion equation well approximates the wave equation in a strong friction limit. We calculate the long wave power spectrum of the wave equation under the assumption that the perturbations are slowly varying in time and the expansion is almost exponential. Under the assumption that the noise has a form invariant under coordinate transformations we obtain the power spectrum close to the scale invariant one. In the diffusion approximation we go beyond the slow variation assumption. We calculate the power spectrum exactly in models with exponential inflation and polynomial potentials and with power-law inflation and exponential potentials.

description: In view of its increasing importance, and the dearth of information on return migration and its impacts on source households, this study uses data from the 2005 Albania Living Standards Measurement Study survey and assesses the impact of past migration experience of Albanian households on non-farm business ownership through instrumental variables regression techniques. Moreover, considering the differences in earning potentials and opportunities for skill acquisition in different destination countries, the impact of household past migration experience is differentiated by main migrant destinations, namely Greece, and Italy. The study also tests for the hypothesis of the existence of migration cycles, by differentiating the time spent abroad based on the year of return. The empirical results indicate that household past migration experience exerts a positive impact on the probability of owning a non-farm business. While one additional year in Greece increases the probability of household business ownership by roughly 7 percent, a similar experience in Italy or further destinations raises the probability by over 30 percent. Although past migration experience for the period of 1990-2000 is positively associated with the likelihood of owning a household enterprise, a similar impact does not materialize for the period of 2001-2004. The latter finding seems suggestive of the fact that more recent migrants are yet to attain a target level of required savings and skills in order to successfully establish a new business upon return.

The Risks of adverse outcomes (maternal and foetal) in hypertensive disorders of pregnancy
Creators: name: Ukah, Ugochinyere Vivian
Publisher: name: The University of British Columbia
Year: 2014

description: The hypertensive disorders of pregnancy are some of the major contributors to maternal and neonatal/perinatal morbidity and deaths resulting from them. There have been studies conducted to investigate the incidence of these hypertensive disorders of pregnancy (HDP) especially pre-eclampsia but the studies investigating the occurrence of adverse outcomes from the HDP are very limited in number. The outcomes from HDP can be severe and lethal and therefore deserve to be focused on as well. This term paper discusses the hypertensive disorders of pregnancy and the most common predictive factors being used and describes few studies that have examined the use some of these factors in predicting adverse maternal and foetal complications. Predicting the adverse outcomes resulting from HDP with timely, non-invasive and effective methods will not only contribute to the management of hypertension in pregnancy, thereby reducing maternal and foetal morbidity and mortality but will also aid in the best use of limited resources in healthcare.
Using quasar X-ray and UV flux measurements to constrain cosmological model parameters

description: Risaliti and Lusso have compiled X-ray and UV flux measurements of 1598 quasars (QSOs) in the redshift range $0.036 \leq z \leq 5.1003$, part of which, $z \sim 2.4 - 5.1$, is largely cosmologically unprobed. In this paper we use these QSO measurements, alone and in conjunction with baryon acoustic oscillation (BAO) and Hubble parameter [$H(z)$] measurements, to constrain cosmological parameters in six different cosmological models, each with two different Hubble constant priors. In most of these models, given the larger uncertainties, the QSO cosmological parameter constraints are mostly consistent with those from the $H(z)$ + BAO data. A somewhat significant exception is the non-relativistic matter density parameter $Ω_{m0}$ where the QSO data favors $Ω_{m0} \sim 0.5 - 0.6$ in most models. Consequently in joint analyses of QSO data with $H(z)$ + BAO data the one-dimensional $Ω_{m0}$ distributions shift slightly toward larger values. A joint analysis of the QSO + $H(z)$ + BAO data is consistent with the current standard model, spatially-flat $Λ$CDM, but mildly favors closed spatial hypersurfaces and dynamical dark energy. Since the higher $Ω_{m0}$ values favored by the QSO data appear to be associated with the $z \sim 2 - 5$ part of these data, and conflict somewhat with strong indications for $Ω_{m0} \sim 0.3$ from most $z < 2.5$ data as well as from the cosmic microwave background anisotropy data at $z \sim 1100$, in most models, the larger QSO data $Ω_{m0}$ is possibly more indicative of an issue with the $z \sim 2 - 5$ QSO data than of an inadequacy of the standard flat $Λ$CDM model.

description: While kinetic Monte Carlo simulations can provide long-time simulations of the dynamics of physical and chemical systems, it is not yet possible in general to identify the inverse Monte Carlo attempt frequency with a physical timescale. Here we demonstrate such an identification by comparing simulations with experimental data. Using a dynamic lattice-gas model for the electrosorption of Br on Ag(100), we measure the scan-rate dependence of the separation between positive-and negative-going peaks in cyclic-voltammetry (CV) and compare simulated and experimental peak separations. By adjusting the Monte Carlo attempt frequency, good agreement between simulated and experimental peak separations is achieved. It is also found that the uniqueness of such a determination is dependent on the relative values of the adsorption/desorption and diffusion free-energy barriers.

description: Mothers are able to identify the body odour (BO) of their own child and prefer this smell above other BOs. It has hence been assumed that the infantile BO functions as a chemosignal promoting targeted parental care. We tested this hypothesis and examined whether children's BOs signal genetic similarity and developmental status to mothers. In addition, we assessed whether BOs facilitate inbreeding avoidance (Westermarck effect). In a cross-sectional design, N = 164 mothers participated with their biological children (N = 226 children, aged 0–18 years) and evaluated BO probes of their own and four other, sex-matched children. Those varied in age and in genetic similarity, which was assessed by human leucocyte antigen profiling. The study showed not only that mothers identified and preferred their own child's BO, but also that genetic similarity and developmental status are transcribed in BOs. Accordingly, maternal preference of their own child's odour changes throughout development. Our data partly supported the Westermarck effect: Mothers preference of pubertal boys' BOs was negatively related to testosterone for the own son, but not for unfamiliar children.This article is part of the Theo Murphy meeting issue ‘Chemical communication in humans’.

description: We obtain very stringent bounds on the possible cold dark matter, baryon and neutrino isocurvature contributions to the primordial fluctuations in the Universe, using recent cosmic microwave background and large scale structure data. In particular, we include the measured temperature and polarization power spectra from WMAP and ACBAR, as well as the matter power spectrum from the 2dF galaxy redshift survey. Neglecting the possible effects of spatial curvature, tensor perturbations and reionization, we perform a Bayesian likelihood analysis with nine free parameters, and find that the amplitude of the isocurvature component cannot be larger than about 31% for the cold dark matter mode, 91% for the baryon mode, 76% for the neutrino density mode, and 60% for the neutrino velocity mode, at 2-sigma, for uncorrelated models. On the other hand, for correlated adiabatic and isocurvature components, the fraction could be slightly larger. However, the cross-correlation coefficient is strongly constrained, and maximally correlated/anticorrelated models are disfavored. This puts strong bounds on the curvaton model, independently of the bounds on non-Gaussianity.

description: In the proof-of-stake (PoS) paradigm for maintaining decentralized, permissionless cryptocurrencies, Sybil attacks are prevented by basing the distribution of roles in the protocol execution on the stake distribution recorded in the ledger itself. However, for various reasons this distribution cannot be completely up-to-date, introducing a gap between the present stake distribution, which determines the parties' current incentives, and the one used by the protocol. In this paper, we investigate this issue, and empirically quantify its effects. We survey existing provably secure PoS proposals to observe that the above time gap between the two stake distributions, which we call stake distribution lag, amounts to several days for each of these protocols. Based on this, we investigate the ledgers of four major cryptocurrencies (Bitcoin, Bitcoin Cash, Litecoin and Zcash) and compute the average stake shift (the statistical distance of the two distributions) for each value of stake distribution lag between 1 and 14 days, as well as related statistics. We also empirically quantify the sublinear growth of stake shift with the length of the considered lag interval. Finally, we turn our attention to unusual stake-shift spikes in these currencies: we observe that hard forks trigger major stake shifts and that single real-world actors, mostly exchanges, account for major stake shifts in established cryptocurrency ecosystems.

This potential leads to the appearance of lcalized states at a distance ξ_0 from the central axis. The twist ωof the strip plays the role of a magnetic field and is responsable for the appearance of these localized states and an effective transverse electric field thus this is reminiscent of the quantum Hall effect. At very low temperatures the twisted configuration of the strip may be stalilized by the electronic states.

description: Neutron imaging is one of the key technologies for non-destructive transmission testing. Recent progress in the development of intensive neutron sources allows us to perform energy-resolved neutron imaging with high spatial resolution. Substantial efforts have been devoted to developing a high spatial and temporal resolution neutron imager. We have been developing a neutron imager aiming at conducting high spatial and temporal resolution imaging based on a delay-line neutron detector, called the current-biased kinetic-inductance detector, with a conversion layer $^{10}$B. The detector allowed us to obtain a neutron transmission image with four signal readout lines. Herein, we expanded the sensor active area, and improved the spatial resolution of the detector. We examined the capability of high spatial resolution neutron imaging over the sensor active area of 15 $\times$ 15 mm$^2$ for various samples, including biological and metal ones. We also demonstrated an energy-resolved neutron image in which stainless-steel specimens were discriminating of other specimens with the aid of the Bragg edge transmission.

Ακολούθως, πραγματοποιήθηκε περιπτωσιολογική μελέτη, κατά την οποία εξετάστηκαν σε αντιπαραβολή δύο διαφημιστικές καμπάνιες της εταιρείας P&G (Always). Η μία διαφημιστική καμπάνια είναι στην αγγλική γλώσσα και η άλλη αποτελεί το προϊόν της μεταδημιουργίας της για το ελληνικό κοινό (“End period poverty”-«Μην είσαι απούσα»). Οι δύο καμπάνιες εξετάστηκαν σε μικροεπίπεδο και μακροεπίπεδο και εντοπίστηκαν ομοιότητες και διαφορές σε λεκτικό και οπτικό επίπεδο. Τέλος, έγινε σχολιασμός ενός παρακειμένου, μίας διαφήμισης με ίδια θεματική και στόχευση αλλά με διαφορετικό πλαίσιο δημιουργίας.
description: The aim of this paper was to study transcreation, a new practice in the translation field that is being used especially in the advertising and marketing field. At first, a theoretical approach of transcreation was attempted with the citation of relevant bibliographical references. At this point, the terminology that was used in this paper was also listed. Additionally, a case study was conducted, during which we compared two advertising campaigns of the company P&G (Always). The first advertising campaign is in English and the other one is the result of its transcreation for the Greek market (“End period poverty”-“Don’t be absent”). The two campaigns were studied in microlevel and macrolevel, while at the same time similarities and differences at the verbal and visual elements of the campaigns were located. Lastly, a paratext, taken from an advertisement with the same subject and objective but within a different context, was also commented.

description: We discuss the effect of the time evolution of extra dimensions on CMB anisotropies and large-scale structure formation. We study the impact of scalar fields in a low-energy effective description of a general class of brane world models on the temperature anisotropy power spectrum. We show that when the coupling between these scalar fields and matter evolves over cosmological timescales, current observations of the CMB anisotropies can constrain primordial values of the fields in a manner complementary to local, late-time tests of gravity. We also present the effect of these fields on the polarization anisotropy spectra and the growth of large-scale structure, showing that future CMB observations will constrain theories of the Universe involving extra dimensions even further.

description: Pretendemos mirar de cerca los procesos de descomposición de la vida tradicional del romancero. Se ofrece en primer lugar una clasificación preliminar de cada una de las transformaciones que padece el romance en su fase actual, en los niveles intratextual y etnopoético. A partir de algunos estudios previos, y analizando versiones de temas significativos como La doncella guerrera, Belardo y Valdovinos, Gaiferos libera a Melisendra, Gaiferos y Galván, Flores y Blancaflor o La mala suegra, nos centramos en uno de los fenómenos que están involucrados en esa degradación: la fragmentarización y posterior prosificación. Comparando estos resultados con versiones de cuentos que coinciden con fábulas romancísticas en el último siglo, se exploran las concomitancias y direccionalidades de la evolución de los géneros orales, considerados como partes de una común memoria literaria.

description: Η παρούσα εργασία πραγματεύεται το πρόβλημα του κακού στο Χριστιανισμό, ο οποίος, όπως κάθε θρησκεία, έχει τις δικές του προτάσεις για την υπέρβαση αυτού του προβλήματος. Μέσα στο διάλογο που ανοίγουμε, θα πρέπει να αντιμετωπίσουμε προπαντός το σύγχρονο αθεϊσμό, που στρέφεται κατά του Θεού σα να είναι υπεύθυνος για την ύπαρξη όλου του κακού στον κόσμο. Η επιστροφή στην αληθινή παράδοση των Πατέρων διορθώνει την εικόνα του Θεού, που παραχαράχθηκε με το πέρασμα των χρόνων. Μέσα από το θείο Λόγο και τις θεόπνευστες ρήσεις των πνευματικών ανθρώπων, θα αντιπαρατάξουμε την Παράδοση προς το διαχρονικό πρόβλημα του κακού, ώστε τελικά να οδηγηθούμε στην οριστική λύση του προβλήματος, η οποία βρίσκεται στο πνεύμα της θυσίας, της αγάπης και της ένωσης που διδάσκουν ο ματωμένος Τίμιος Σταυρός και η Ανάσταση του Κυρίου Ιησού Χριστού.
description: This paper deals with the problem of evil in Christianity which, like any religion, has its own proposals for overcoming this problem. In the dialogue we open, we must first and foremost confront modern atheism, which turns against God as being responsible for the existence of all evil in the world. The return to the true tradition of the Fathers corrects the image of God, which has been falsified over the years. Through the divine Word and the divinely inspired sayings of spiritual people, we will oppose Tradition to the timeless problem of evil, so that we may eventually be led to the final solution of the problem, which is in the spirit of sacrifice, love and union taught by the Holy Cross and the Resurrection of the Lord Jesus Christ.

description: Relation Extraction (RE), the task of detecting and characterizing semantic relations between entities in text, has gained much importance in the last two decades, mainly in the biomedical domain. Many papers have been published on Relation Extraction using supervised machine learning techniques. Most of these techniques rely on statistical methods, such as feature-based and tree-kernels-based methods. Such statistical learning techniques are usually based on a propositional hypothesis space for representing examples, i.e., they employ an attribute-value representation of features. This kind of representation has some drawbacks, particularly in the extraction of complex relations which demand more contextual information about the involving instances, i.e., it is not able to effectively capture structural information from parse trees without loss of information. In this work, we present OntoILPER, a logic-based relational learning approach to Relation Extraction that uses Inductive Logic Programming for generating extraction models in the form of symbolic extraction rules. OntoILPER takes profit of a rich relational representation of examples, which can alleviate the aforementioned drawbacks. The proposed relational approach seems to be more suitable for Relation Extraction than statistical ones for several reasons that we argue. Moreover, OntoILPER uses a domain ontology that guides the background knowledge generation process and is used for storing the extracted relation instances. The induced extraction rules were evaluated on three protein-protein interaction datasets from the biomedical domain. The performance of OntoILPER extraction models was compared with other state-of-the-art RE systems. The encouraging results seem to demonstrate the effectiveness of the proposed solution.

description: Σκοπός της παρούσας ερευνητικής εργασίας ήταν η διερεύνηση των αντιλήψεων και των συμπεριφορών του γενικού πληθυσμού για την χρήση των αντηλιακών ανάλογα με την εποχή και την γεωγραφική θέση του τόπου κατοικίας τους. Η ερευνητική μέθοδος στηρίχθηκε στις αρχές της ποσοτικής έρευνας και η έρευνα διενεργήθηκε με δομημένο ερωτηματολόγιο. Προηγήθηκε πιλοτική έρευνα με συμπλήρωση έξι (06) ερωτηματολογίων ενώ το δείγμα του πληθυσμού της κύριας έρευνα το αποτελούσαν 360 άτομα από τέσσερις διαφορετικές πόλεις (Βόλος, Δράμα, Θεσσαλονίκη και Καστοριά). Στα βασικά συμπεράσματα της έρευνας συγκαταλέγονται η θετική εικόνα που έχουν οι συμμετέχοντες για την χρήση του αντηλιακού και τον δείκτη προστασίας (SPF) του ανεξάρτητα από το φύλο και την γεωγραφική θέση της κατοικίας τους στην πρόληψη των ηλιακών εγκαυμάτων και του καρκίνου του δέρματος. Ενδιαφέρον προκάλεσε ότι σε μεγάλο ποσοστό οι συμμετέχοντες ήταν ενημερωμένοι για την Βιταμίνη D. Ωστόσο, επικρατεί η αντίληψη ότι το αντηλιακό είναι αναγκαίο μόνο το καλοκαίρι και όχι σε όλες τις εποχές. Εν κατακλείδι, η γνώση τους για την χρήση των αντηλιακών ήταν πολύ καλή από όλους τους συμμετέχοντες.
description: The purpose of this research was to investigate the perceptions and behaviors of the general population about the use of sunscreens according to the season and the geographical location of their residence. The methodology was based on the principles of quantitative research and the research was conducted with a structured questionnaire. Before the main study, a pilot research was conducted with the use of six (06) completed questionnaires. The sample of the population of the main research consisted of 360 participants from four different cities (Volos, Drama, Thessaloniki and Kastoria). The main findings of the research include the positive attitude that the participants have of the use of sunscreen and its protection index (SPF) regardless of the gender and the geographical location of their residence for the prevention of sunburn and skin cancer. Interestingly, a large percentage of participants were aware of Vitamin D. However, there was a perception that sunscreen is needed only during summer and not during all seasons. In conclusion, the participants’ knowledge about the use of sunscreen was very good.

description: Το δέρμα αποτελεί το κύριο εμπόδιο που προστατεύει τον ανθρώπινο οργανισμό από τους διάφορους τύπους της περιβαλλοντικής ρύπανσης. Τέτοιοι τύποι ρύπανσης μπορούν να θεωρηθούν οι φυσικοί, χημικοί αλλά και βιολογικοί στρεσογόνοι παράγοντες, όπου σε συνδυασμό με εσωτερικούς παράγοντες, ευθύνονται για τη δερματική γήρανση. Η γήρανση του δέρματος δεν συμβαίνει μόνο με το πέρασμα του χρόνου, αλλά και από την έκθεση σε διαφορετικούς περιβαλλοντικούς παράγοντες. Η διαδικασία γήρανσης του δέρματος, η οποία προκαλείται από περιβαλλοντικούς παράγοντες, ονομάζεται πρόωρη ή εξωγενής διαδικασία και μπορεί να διακριθεί από τη χρονολογική (ενδογενή) διαδικασία με χαρακτηριστικά σημάδια. Γνωστοί περιβαλλοντικοί παράγοντες που οδηγούν στην εξωγενή γήρανση του ανθρώπινου δέρματος είναι η έκθεση στον ήλιο και το κάπνισμα.
description: The skin is the main barrier that protects the human body from various types of environmental pollution. Such types of pollution can be considered the physical, chemical and biological stressors, where in combination with internal factors, they are responsible for skin aging. Skin aging occurs not only over time, but also from exposure to various environmental factors. The process of skin aging, which is caused by environmental factors, is called premature or exogenous skin aging process and can be distinguished from the chronological (endogenous) process of skin aging with characteristic signs. Known environmental factors that lead to exogenous skin aging are sun exposure and smoking.
