description: The Sun is a magnetic plasma diffuser that selectively moves light elements like H and He and the lighter isotopes of each element to its surface. The Sun formed on the collapsed core of a supernova. It consists mostly of iron, oxygen, nickel, silicon and sulfur made near the SN core, like the rocky planets and ordinary meteorites. H ions, generated by emission and decay of neutrons at the core, are accelerated upward by deep magnetic fields, thus acting as a carrier gas that maintains mass separation in the Sun. Neutron emission from the central neutron star triggers a series of reactions that generate solar luminosity, solar neutrinos, solar mass-fractionation, and an outpouring of the neutron decay product, H, in the solar wind. Mass fractionation appears to have operated in the parent star as well, and likely occurs in other stars.
description: 20 pages, 92 references, 8 figures show that the Sun is an iron rich magnetic plasma diffuser that selectively moves lightweight elements and isotopes of each element to its surface. Solar luminosity, neutrinos, mass fractionation, and the outpouring of H ions in the solar wind arise from neutron emission and decay at the solar core.

description: An analysis of generating fermion masses via cubic couplings in SO(10) grand unification with a unified Higgs sector is given. The new framework utilizes a single pair of vector--spinor representation $144+\bar{144}$ to break the gauge symmetry all the way to $SU(3)_C \times U(1)_{em}$. Typically the matter--Higgs couplings in this framework are quartic and lead to naturally suppressed Yukawa couplings for the first two generations. Here we show that much larger third generation couplings naturally arise at the cubic level with additional matter in 10--plet and 45--plet representations of SO(10). Thus the physical third generation is a mixture of 16, 10 and 45--plet representations while the remaining components become superheavy and are removed from the low energy spectrum. In this scenario it is possible to understand the heaviness of the top in a natural way since the analysis generates a hierarchy in the Yukawa couplings so that $h_{\textnormal {t}}/h_{\textnormal {b}}>> 1$ where $h_{\textnormal {t}} (h_{\textnormal {b}})$ are the top (bottom) Yukawa couplings. It is then possible to realize values of $\tanβ$ as low as 2, which also helps to stabilize the proton.

description: In this contribution to the special issue on multiferroics we focus on multiferroicity driven by different forms of charge ordering. We will present the generic mechanisms by which charge ordering can induce ferroelectricity in magnetic systems. There is a number of specific classes of materials for which this is relevant. We will discuss in some detail $(i)$ perovskite manganites of the type (PrCa)MnO$_3$, $(ii)$ the complex and interesting situation in magnetite Fe$_3$O$_4$, $(iii)$ strongly ferroelectric frustrated LuFe$_2$O$_4$, $(iv)$ an example of a quasi one-dimensional organic system. All these are "type-I" multiferroics, in which ferroelectricity and magnetism have different origin and occur at different temperatures. In the second part of this article we discuss "type-II" multiferroics, in which ferroelectricity is completely {\it due to} magnetism, but with charge ordering playing important role, such as $(v)$ the newly-discovered multiferroic Ca$_3$CoMnO$_6$, $(vi)$ possible ferroelectricity in rare earth perovskite nickelates of the type RNiO$_3$, $(vii)$ multiferroic properties of manganites of the type RMn$_2$O$_5$, $(viii)$ of perovskite manganites with magnetic E-type ordering and $(ix)$ of bilayer manganites.

description: The first complete orbital solution for the double-lined spectroscopic binary system γ^2 Velorum, obtained from measurements with the Sydney University Stellar Interferometer (SUSI), is presented. This system contains the closest example of a Wolf-Rayet star and the promise of full characterisation of the basic properties of this exotic high-mass system has subjected it to intense study as an archetype for its class. In combination with the latest radial-velocity results, our orbital solution produces a distance of 336^{+8}_{-7} pc, significantly more distant than the Hipparcos estimation (Schaerer et al. 1997; van der Hucht 1997). The ability to fully specify the orbital parameters has enabled us to significantly reduce uncertainties and our result is consistent with the VLTI observational point (Millour et al. 2006), but not with their derived distance. Our new distance, which is an order of magnitude more precise than prior work, demands critical reassessment of all distance-dependent fundamental parameters of this important system. In particular, membership of the Vela OB2 association has been reestablished, and the age and distance are also in good accord with the population of young stars reported by Pozzo et al. (2000). We determine the O-star primary component parameters to be M_V(O) = -5.63 \pm 0.10 mag, R(O) = 17 \pm 2 R_{\sun} and {\cal M}(O) = 28.5 \pm 1.1 M_{\sun}. These values are consistent with calibrations found in the literature if a luminosity class of II--III is adopted. The parameters of the Wolf-Rayet component are M_v(WR) = -4.33 \pm 0.17 mag and {\cal M}(WR) = 9.0 \pm 0.6 M_{\sun}.

description: While urban technology exerts a positive effect on rural development through knowledge spillovers, it also raises the competitive advantage of urban firms over rural firms in product market competition. Urban technology also affects the rural labour market through brain drain. Using US county-level data, we find a negative relationship between metropolitan patent counts and non-metropolitan labour market performance. Our basic calculation indicates that, between 2005 and 2015, metropolitan technological progress was associated with a relative loss of about 2.5 million non-metropolitan jobs.

description: Generating and controlling spin current (SC) are of central interest in spin physics and applications. To date, the spin-orbit interaction (SOI) is an established pathway to generate SC through the spin-charge current conversion. We predict an efficient spin-light conversion via the Rashba and higher-order cubic Dresselhaus SOIs in ferroelectrics. Different from the known Edelstein effect, where SC is created by the nonequilibrium spin density, our predicted spin-polarized current is from direct interactions between light and unique spin textures generated by SOI in ferroelectrics. Using first-principles simulations, we demonstrate these concepts by calculating the DC spin photocurrent in a prototypical Rashba ferroelectric, α-GeTe. The photo-induced SC is about two orders of magnitude larger than the charge photocurrent. More importantly, we can conveniently switch the direction of SC by an applied electric field via inverting the spin textures. These predictions give hope to generating and controlling light-driven SC via nonvolatile electric-field.

We give an algorithm for computing the degree of R_{d} under a "generalized Plücker embedding", this is a certain Gromov-Witten invariant. The approach is to apply the Atiyah-Bott localization formula for the natural C^{*}-action on R_{d}. These numbers can be obtained directly from Vafa-Intriligator formula.

description: In this paper we analyse the unintended effects of a national policy. We explore how national payroll taxes policies can explain changes in wage gaps between cities. To do so, we exploit a payroll tax reform implemented in 2012 in Colombia. Using monthly data between 2011 and 2014, we estimate the effect of this policy in the lower part of the income distribution, and in particular at a window around the minimum wage, relying on a triple-difference estimation. Our results suggest that national policies aimed at reducing informality can have important effects in reducing wage gaps across cities.

description: Two competing paradigms to modelling the impacts of regional economic shocks have arisen: ‘disequilibrium’ models, which predict that regional economies eventually fully recover, and ‘no-equilibrium’ models, which predict economic shocks have a permanent effect. To address this controversy, we adapt contemporary model-averaging methods to optimally combine both paradigms and thereby permit intermediate cases in which recoveries can be partial. Applying our method to a set of labour market models that span the disequilibrium and no-equilibrium paradigms, we find that regional recoveries are incomplete, implying that downturns have long-lasting effects on regional unemployment rates.

description: Local institutions in the shape of collective wage bargaining in firms are important for wage differences among labour of various origins. This paper considers local rent-sharing in Danish firms and finds that local wage bargaining reduces wage gaps between cross-border commuters of Danish, Swedish, German and Polish origins. Wage gaps are found to be between 6% and 12%, while individual union membership reduces the wage gap. Local peer effects, on the other hand, may increase wage gaps particularly for cross-border commuters of Polish origin, which can be interpreted as a form of local club behaviour in bargaining at the firm level.

description: Can Geographical Indications (GIs) promote local economic development in rural areas? This paper explores the impact of GIs that identify and endorse agri-food products which are strictly embedded within the territory from which they originate. Examining Italian wine protected by GIs through an innovative dataset and by means of propensity score matching and difference-in-differences models make it possible to compare the local economic development trajectories of rural municipalities afforded GIs with the correspondent dynamics of a counterfactual group of similar municipalities without GI status since 1951. Rural municipalities with GIs experience population growth and economic reorganization towards non-farming sectors, which frequently involve higher value-added activities.

description: The study examines the relationship between immigration and regional housing markets using wavelet coherence analysis in conjunction with Granger causality tests. We find that while there are some regional differences in the relationships, the impact of immigration on house rents is consistently more pronounced than the impact on house prices and, in the short to medium term, an increase in immigration leads to a decrease in price-to-rent ratios. The study uses data sets for different regional housing markets in New Zealand, a country with one of the highest immigration-to-population ratios in the world during the sample period of 1996–2017.

description: Despite the positive contributions of several European Union (EU) policies to reduce border barriers, the EU Cross-Border Review (CBR) initiative reaffirmed their relevance and persistence. Since 2018, the EU has supported the b-solutions initiative, specifically focused on tackling legal and administrative border obstacles, aiming to highlight replicable solutions which can contribute to reducing these obstacles. This article critically assesses the b-solutions and its contribution to reducing administrative and legal border obstacles, with an eye to promoting a more integrated European territory. It is concluded that b-solutions is a valid, yet insufficient, initiative to provide replicable solutions to mitigate cross-border barriers.

description: The extra-dimensional origin of dark matter is a fascinating and nowadays often discussed possibility. Here, we present the gamma-ray signatures that are expected from the self-annihilation of Kaluza-Klein dark matter particles. For comparison, we contrast this with the case of supersymmetry, where the neutralino annihilation spectra take a very different form. In both cases we find pronounced spectral signatures that could in principle be used to distinguish between these two types of dark matter candidates already with today's detector resolutions.

Investigation of strut-ramp injector in a Scramjet combustor: effect of strut geometry, fuel and jet diameter on mixing characteristics

description: The strut based injector has been found to be one of the most promising injector designs for supersonic combustor, offering en-hanced mixing of fuel and air. The mixing and flow field characteristics of the straight (SS) & tapered strut (TS), with fixed ramp an-gle and height at freestream Mach number 2 in conjunction with fuel injection at Mach 2.3 have been investigated numerically and reported. In the present investigation, hydrogen (H2) and ethylene (C2H4) are injected in oncoming supersonic flow from the back of the strut, where jet to freestream momentum ratio is maintained at 0.79 and 0.69 for H2 & C2H4, respectively. The predicted wall static pressure and species mole fractions at various downstream locations are compared with the experimental data for TS case with 0.6 mm jet diameter and found to be in good agreement. Further, the effect of jet diameter and strut geometry on the near field mixing in strut ramp configuration is discussed for both the fuel. The numerical results are assessed based on various parameters for the performance evaluation of different strut ramp configurations. The SS configuration for both the injectant is found to be an optimum candidate, also it is observed that for higher jet diameter larger combustor length is required to achieve satisfactory near field mixing.

description: This paper discusses a nonparametric regression model that naturally generalizes neural network models. The model is based on a finite number of one-dimensional transformations and can be estimated with a one-dimensional rate of convergence. The model contains the generalized additive model with unknown link function as a special case. For this case, it is shown that the additive components and link function can be estimated with the optimal rate by a smoothing spline that is the solution of a penalized least squares criterion.

description: Historic cultural institutions are known to predict local inequality, but the moderating effect of modern cultural attitudes has not been thoroughly elucidated. Our hypothesis is that local inequality is determined by a moderating mechanism based on the balance between cultural heritage and living culture. We use a unique panel dataset for Italian regions, covering the period 2007–16, and observe that regional inequality decreases where cultural heritage interacts with a more altruistic modern living culture. A finite mixture model suggests spatial clustering of inequality, dividing Italy into three areas. This reveals cultural capital-driven frictions in the spatial redistribution of human capital.

We work in the Regge limit of QCD and use the NLO BFKL results. A jet cone definition is proposed together with a phase-space separation into multi-Regge and quasi-multi-Regge kinematics. We discuss scattering of highly virtual photons, with a symmetric energy scale to separate the impact factors from the gluon Green's function, and hadron-hadron collisions, with a non-symmetric scale choice.

description: A $ϕ$-irreducible and aperiodic Markov chain with stationary probability distribution will converge to its stationary distribution from almost all starting points. The property of Harris recurrence allows us to replace ``almost all'' by ``all,'' which is potentially important when running Markov chain Monte Carlo algorithms. Full-dimensional Metropolis--Hastings algorithms are known to be Harris recurrent. In this paper, we consider conditions under which Metropolis-within-Gibbs and trans-dimensional Markov chains are or are not Harris recurrent. We present a simple but natural two-dimensional counter-example showing how Harris recurrence can fail, and also a variety of positive results which guarantee Harris recurrence. We also present some open problems. We close with a discussion of the practical implications for MCMC algorithms.

description: The properties of spin polarized neutron matter are studied both at zero and finite temperature using the D1 and the D1P parameterizations of the Gogny interaction. The results show two different behaviors: whereas the D1P force exhibits a ferromagnetic transition at a density of $ρ_c \sim 1.31$ fm$^{-3}$ whose onset increases with temperature, no sign of such a transition is found for D1 at any density and temperature, in agreement with recent microscopic calculations.

description: We propose a residual randomization procedure designed for robust Lasso-based inference in the high-dimensional setting. Compared to earlier work that focuses on sub-Gaussian errors, the proposed procedure is designed to work robustly in settings that also include heavy-tailed covariates and errors. Moreover, our procedure can be valid under clustered errors, which is important in practice, but has been largely overlooked by earlier work. Through extensive simulations, we illustrate our method's wider range of applicability as suggested by theory. In particular, we show that our method outperforms state-of-art methods in challenging, yet more realistic, settings where the distribution of covariates is heavy-tailed or the sample size is small, while it remains competitive in standard, "well behaved" settings previously studied in the literature.

description: P2P systems are a great solution to the problem of distributing resources. The main issue of P2P networks is that searching and retrieving resources shared by peers is usually expensive and does not take into account similarities among peers. In this paper we present preliminary simulations of PROSA, a novel algorithm for P2P network structuring, inspired by social behaviours. Peers in PROSA self--organise in social groups of similar peers, called ``semantic--groups'', depending on the resources they are sharing. Such a network smoothly evolves to a small--world graph, where queries for resources are efficiently and effectively routed.

description: Most of the turbulence models in practice are based on the assumption of a linear relation between Reynolds stresses and mean flow strain rates which generally provides a good approximation in case of attached and fully turbulent flows. A two dimensional numerical study has been carried out over NACA 0021 with k-ωSST model with non-linear correction at Re = 120,000 for various angles of attack which experiences the formation of a laminar separation bubble (LSB). A correct prediction of LSB requires an accurate resolution of anisotropy in Reynolds stresses. For comparison with other linear models, the simulations are also performed with k-kl-ω, k-ωSST and Spalart Allmaras. The performance of these models is assessed through aerodynamic lift, drag, pressure and friction coefficients. It is found that the non-linear k-ωSST and k-kl-ωtransition model provide comparable quality of prediction in lift and drag coefficients (in spite of the fact that non-linear k-ωSST involves solving less number of transport equation than the transition model) as observed in the experiments whereas k-ωSST and SA models under predict the drag coefficient value at low angle of attack due to inability to capture the separation induced transition. It is also observed that the location of laminar separation bubble is captured accurately when nonlinear or transition model is used as opposed to the SA or linear SST models, which lack in the ability to predict the same.

description: Η παρούσα εργασία εξετάζει τη φιλοσοφική θεώρηση του Καντ, επικεντρώνοντας ιδιαίτερα στα ζητήματα της τέχνης και της ανθρωπολογίας, όπως αυτά αναλύονται στο έργο του μεγάλου Γερμανού φιλοσόφου. Αρχικά δίνονται τα γενικά στοιχεία της καντιανής φιλοσοφίας, αναλύοντας το γενικό φιλοσοφικό θεώρημα του Καντ, ενώ στη συνέχεια παρουσιάζονται οι βασικές σκέψεις του διανοητή σε σχέση με τη λειτουργία της κριτικής, η οποία αποτελεί και τη βασικότερη καινοτομία του Καντ στη φιλοσοφική σκέψη, όπως την πραγματεύεται ο ίδιος στα άρτια έργα της ώριμης περιόδου του, Κριτική του Καθαρού Λόγου, Κριτική του Πρακτικού Λόγου και Κριτική της Κριτικής Δύναμης. Το ερευνητικό αυτό εγχείρημα στέκεται ιδιάιτερα στο τρίτο αυτό έργο, Κριτική της Κριτικής Δύναμης, καθώς σε αυτό μπαίνουν οι βάσεις της καντιανής αισθητικής θεωρίας, η οποία εξετάζεται στη συνέχεια, όπως και τα ιδιαίτερα στοιχεία της φιλοσοφικής σκέψης του Καντ σχετικά με το ζήτημα της τέχνης, η αντίληψή του για το ωραίο και το υψηλό και η διαίρεση την οποία εισάγει για τις καλές τέχνες. Τέλος, επιχειρείται μια προσέγγιση στις αντιλήψεις του Καντ για τον άνθρωπο, την προέλευση του είδους και των κοινωνιών του, όπως και η αντίληψή του για τα ζητήματα της Ιστορίας και της Θεολογίας
description: The present project the philosophical consideration of Kant, relating to the issues of art and anthropology the way they are analysed in the work of the great German philosopher. Initially the general elements of Kant’s philosophy are given analyzing the general philosophical theory, while his basic thoughts are presented related to criticism, the most important innovation in Kants philosophical thoughts. All these are presented in a perfect way in the works of his mature period, “Critique of Pure Reason”, “Critique of Practical Reason”, “Critique of critical Power”. This research process concentrates on his third project, critique of critical power, because in this project one can find the bases of Kants aesthetic theory, in which the particular element of philosophical thought are analyzed in relation to art, his perception of beauty and the high and the division he introduces about fine arts. Finally, there is an effort of approaching Kants believes for human societies, the origin of his kind and his believes for history and theology

Tracing the [FeII]/[NeII] ratio and its relationship with other ISM indicators within star forming dwarf galaxies: a Spitzer IRS archival study

description: Archival Spitzer observations of 41 starburst galaxies that span a wide range in metallicity reveal for the first time a correlation between the [FeII]/[NeII] 26.0/12.8 micron ratio and the electron gas density as traced by the 18.7/33.4 micron [SIII] ratio, with the [FeII]/[NeII] ratio decreasing with increasing gas density. The correlations of the [FeII]/[NeII] ratio, the PAH peak to continuum strength & metallicity found in an earlier paper were confirmed for a larger sample. We also find a strong correlation between the gas density and the PAH peak to continuum strength. Using shock and photoionization models, we see the driver of the observed [FeII]/[NeII] ratios is metallicity. The majority of [FeII] emission in low metallicity galaxies may be shock-derived, whilst at high metallicity, the [FeII] emission may be instead dominated by contributions from HII and in particular from dense PDR regions. However, the observed [FeII]/[NeII] ratios may instead be following a metallicity-abundance relationship, with iron being less depleted onto grains in low metallicity galaxies - a result that would have profound implications for the use of iron emission lines as unambiguous tracers of shocks.

description: The grip force required to handle an object depends on the object's mass and the friction coefficient of its surface. The control of grip force in myoelectric prosthesis is crucial for handling objects adequately. In the current paper we propose a new method for improving the proportional and continuous grasping force estimation to improve control systems for myoelectric prosthesis based on surface electromyography (sEMG) recordings. For this purpose, we develop an approach based on multivariable system identification in the state-space (SS) and continuous force estimation with Kalman Filter (KF). The sEMG recordings of ten healthy individuals performing a grip task were used as data set for model identification. The root mean square (RMS), the mean absolute value (MAV), and the waveform length (WL) extracted from the sEMG signals were used at the model's input while the measured grasping force was the output. The performance of the method was evaluated with the normalized root-mean-squared-error (NRMSE) and the square of the Pearson's correlation coefficient ($ R^2 $). We found the $R^2$ and NRMSE values were 0.92$ \pm $ 0.0319 and 0.723$ \pm $ 0.0563, respectively. The performance of the proposed technique was superior to the results obtained with other regression models, such as the recurrent nonlinear autoregressive exogenous (NARX)-based neural network, the multi-layer perceptron (MLP) network and the linear discriminant analysis (LDA) with a quadratic polynomial fitting (QPF). The results confirm that the method is adequate for real-time applications with myoelectric hand prostheses.
