description: Chebyshev observed in a letter to Fuss that there tends to be more primes of the form $4n+3$ than of the form $4n+1$. The general phenomenon, which is referred to as Chebyshev's bias, is that primes tend to be biased in their distribution among the different residue classes $\bmod q$. It is known that this phenomenon has a strong relation with the low-lying zeros of the associated $L$-functions, that is if these $L$-functions have zeros close to the real line, then it will result in a lower bias. According to this principle one might believe that the most biased prime number race we will ever find is the Li$(x)$ versus $π(x)$ race, since the Riemann zeta function is the $L$-function of rank one having the highest first zero. This race has density 0.99999973..., and we study the question of whether this is the highest possible density. We will show that it is not the case, in fact there exists prime number races whose density can be arbitrarily close to 1. An example of race whose density exceeds the above number is the race between quadratic residues and non-residues modulo 4849845, for which the density is 0.999999928... We also give fairly general criteria to decide whether a prime number race is highly biased or not. Our main result depends on the General Riemann Hypothesis and on a hypothesis on the multiplicity of the zeros of a certain Dedekind zeta function. We also derive more precise results under a linear independence hypothesis.

description: Apesar de relegada muitas vezes para um plano secundário, quando comparada com a lei eleitoral da Assembleia da República, a lei eleitoral do Presidente da República tem antecedentes e um percurso de vida, cujo conhecimento não deve ser ignorado por quantos estudam o sistema político do regime democrático português. Trata-se afinal de compreender como se chegou à forma de eleição do Presidente da República, perceber que passos foram dados para permitir o voto dos cidadãos portugueses residentes no estrangeiro, e saber que sobre estas questões existiram clivagens que muito dividiram políticos e partidos. Conhecer os antecedentes e o percurso de quarenta e cinco anos de vida da actual lei eleitoral do Presidente da República é o objectivo deste estudo.
description: Although sidelined very often by, and when compared to the parliamentarian electoral law, the electoral law for the President of the Republic has past examples and a history, of which its knowledge should not be ignored by those who study the Political System of the Portuguese Democratic Regime. It is about understanding how we arrived at this way of electing the President of the Republic, to figure the steps taken to allow portuguese citizens living abroad to vote, and to identify the issues which deeply divided politicians and political parties. To know the previous cases and its forty-five-year long journey of the current electoral law for the President of the Republic is the goal of this study.
A simple and robust method for automated photometric classification of supernovae using neural networks

description: A method is presented for automated photometric classification of supernovae (SNe) as Type-Ia or non-Ia. A two-step approach is adopted in which: (i) the SN lightcurve flux measurements in each observing filter are fitted separately; and (ii) the fitted function parameters and their associated uncertainties, along with the number of flux measurements, the maximum-likelihood value of the fit and Bayesian evidence for the model, are used as the input feature vector to a classification neural network (NN) that outputs the probability that the SN under consideration is of Type-Ia. The method is trained and tested using data released following the SuperNova Photometric Classification Challenge (SNPCC). We consider several random divisions of the data into training and testing sets: for instance, for our sample D_1 (D_4), a total of 10% (40%) of the data are involved in training the algorithm and the remainder used for blind testing of the resulting classifier; we make no selection cuts. Assigning a canonical threshold probability of p_th=0.5 on the NN output to classify a SN as Type-Ia, for the sample D_1 (D_4) we obtain a completeness of 0.78 (0.82), purity of 0.77 (0.82), and SNPCC figure-of-merit of 0.41 (0.50). Including the SN host-galaxy redshift and its uncertainty as additional inputs to the NN results in a modest 5-10% increase in these values. We find that the classification quality does not vary significantly with SN redshift. Moreover, our probabilistic classification method allows one to calculate the expected completeness, purity or other measures of classification quality as a function of the p_th, without knowing the true classes of the SNe in the testing sample. The method may thus be improved further by optimising p_th and can easily be extended to divide non-Ia SNe into their different classes.

description: A presente reflexão resulta da confrontação entre a necessidade de existência de critérios claros aplicáveis em sede de reconhecimento como «religiosas» práticas e doutrinas relativas a determinado grupo de culto, no processo de acreditação jurídica como Pessoa Coletiva Religiosa por parte do Registo Nacional de Pessoas Coletivas em Portugal, e um olhar teórico multiverso inerente à disciplina da Antropologia religiosa. Tendo presente que a Lei da Liberdade Religiosa (lei n.º 16/2001 de 22 de Junho) não estabelece os critérios objetivos e formais para o efeito, considera-se existir uma vaguidade doutrinária que não garante segurança jurídica para as comunidades religiosas não-abraâmicas, nem respeita o princípio da igualdade para as religiões minoritárias, uma vez que tenderá a vigorar um paradigma judaico-cristão como critério de analogia. O presente texto pretende resolver essa questão.

Bearing in mind that the Law on Religious Freedom (law no. 16/2001 of 22nd June) does not establish objective and formal criteria for this purpose, it is considered that there is a doctrinal vagueness that does not ensure legal security for non-Abrahamic religious communities, nor does it respect the principle of equality for minority religions, since a Judeo-Christian paradigm will tend to prevail as a criterion of analogy. The present text intends to resolve this conundrum.

description: Questo intervento analizza le rappresentazioni dell’identità giovanile italiana nei film Musicarelli, una serie di film musicali prodotti per un pubblico giovane negli anni Sessanta. In questi film, i giovani vengono rappresentati come soggetto docile, e lo scontro generazionale tende ad essere risolto attraverso una riappacificazione tra i giovani e i loro antagonisti adulti. Tuttavia, i Musicarelli presentano anche strategie quali l’uso di parodie e il riferimento a fatti di cronaca che introducono un ribaltamento dei rapporti di potere tra le generazioni. Il film Rita la Zanzara (Wertmüller 1966) viene utilizzato come case study per discutere questa duplice funzione.

description: Canonical analysis has long been the primary analysis method for studies of phase transitions. However, this approach is not sensitive enough if transition signals are too close in temperature space. The recently introduced generalized microcanonical inflection-point analysis method not only enables the systematic identification and classification of transitions in systems of any size, but it can also distinguish transitions that standard canonical analysis cannot resolve. By applying this method to a generic coarse-grained model for semiflexible polymers, we identify a mixed structural phase dominated by secondary structures such as hairpins and loops that originates from a bifurcation in the hyperspace spanned by inverse temperature and bending stiffness. This intermediate phase, which is embraced by the well-known random-coil and toroidal phases, is testimony to the necessity of balancing entropic variability and energetic stability in functional macromolecules under physiological conditions.

description: Taking into account the rotation of mass-accreting white dwarfs (WDs) whose masses exceed the Chandrasekhar mass, we extend our new single degenerate model for the progenitors of Type Ia supernovae (SNe Ia), accounting for two types of binary systems, those with a main sequence companion and those with a red-giant (RG) companion. We present a mass distribution of WDs exploding as SNe Ia, where the WD mass ranges from 1.38 to 2.3 Msun. These progenitor models are assigned to various types of SNe Ia. A lower mass range of WDs (1.38 Msun < M_WD ~ 1.5 Msun), which are supported by differential rotation, correspond to brighter SNe Ia such as SN 1991T. In this case, a variety of the WD mass may lead to a variation of brightness. We also show the evolutionary states of the companion stars at SN Ia explosions and pose constraints on the unseen companions. In the WD+RG systems, in particular, most of the RG companions have evolved to helium/carbon-oxygen WDs in the spin-down phase before the SN Ia explosions. In such a case, we do not expect any prominent signature of the companion immediately before and after the explosion. We also compare our new models with the recent stringent constraints on the unseen progenitors of SNe Ia such as SN 2011fe.

In particular, we discuss the in-medium effects on elementary hyperon-nucleon ($YN$) channels, which are relevant for the production of hypernuclei at PANDA. The results indicate strong in-medium effects on $YN$-scattering, which might be important for hypernuclear studies at PANDA.

description: An extended study of the superconducting and normal-state properties of various as-grown and post-annealed RbxFe2-ySe2 single crystals is presented. Magnetization experiments evidence that annealing of RbxFe2-ySe2 at 413 K, well below the onset of phase separation Tp=489 K, neither changes the magnetic nor the superconducting properties of the crystals. In addition, annealing at 563 K, well above Tp, suppresses the superconducting transition temperature Tc and leads to an increase of the antiferromagnetic susceptibility accompanied by the creation of ferromagnetic impurity phases, which are developing with annealing time. However, annealing at T=488K=Tp increases Tc up to 33.3 K, sharpens the superconducting transition, increases the lower critical field, and strengthens the screening efficiency of the applied magnetic field. Resistivity measurements of the as-grown and optimally annealed samples reveal an increase of the upper critical field along both crystallographic directions as well as its anisotropy. Muon spin rotation and scanning transmission electron microscopy experiments suggest the coexistence of two phases below Tp: a magnetic majority phase of Rb2Fe4Se5 and a non-magnetic minority phase of Rb0.5Fe2Se2. Both microscopic techniques indicate that annealing the specimens just at Tp does not affect the volume fraction of the two phases, although the magnetic field distribution in the samples changes substantially. This suggests that the microstructure of the sample, caused by mesoscopic phase separation, is modified by annealing just at Tp, leading to an improvement of the superconducting properties of RbxFe2-ySe2 and an enhancement of Tc.

description: Situated language use is influenced by a number of dynamic phenomena that introduce lexical variability and path dependence, such as fluid discourse granularity, priming, and alignment in dialogue. The empirical tradition of usage-based lexicology does not account for such variability. In fact, its primary theoretical approaches appear to presuppose high population convergence on particular lexemes in language production. This is implied in several key concepts of phraseological and constructionist models, notably entrenchment, the principle of no synonymy, and the idiom principle, as well as the dominance of the statistical paradigm in the field. In spite of its relevance for linguistic theory and corpus methodology, this assumption appears to be untested. This study provides an analysis of inter-individual lexical overlap of verbs and nouns in five task-based corpora of (mostly) German. Results indicate that speakers are maximally variable and highly divergent in their lexical use in spite of narrow communicative constraints and group homogeneity. A qualitative analysis links this variability to situational (cognitive, socio-pragmatic, and discourse-level) engagement with the task and material, which results in referential diversity, spontaneous meaning mapping, and abundant word formation. The degree of observed variability raises questions with respect to the stochastic properties and functional mechanics of entrenchment and the role of repetition of identical material, such as lexicalized chunks, in conventionalization. It further emphasizes the need for a better understanding of the distributions that underlie pooled data, without which the validity of frequential extrapolation to individual behavior and system status stands to question. This is of particular relevance to language assessment and other practices of contrastive analysis of speaker productions, e.g., in multilingualism studies.

description: We address the problem of configuring a power distribution network with reliability and resilience objectives by satisfying the demands of the consumers and saturating each production source as little as possible. We consider power distribution networks containing source nodes producing electricity, nodes representing electricity consumers and switches between them. Configuring this network consists in deciding the orientation of the links between the nodes of the network. The electric flow is a direct consequence of the chosen configuration and can be computed in polynomial time. It is valid if it satisfies the demand of each consumer and capacity constraints on the network. In such a case, we study the problem of determining a feasible solution that balances the loads of the sources, that is their production rates. We use three metrics to measure the quality of a solution: minimizing the maximum load, maximizing the minimum load and minimizing the difference of the maximum and the minimum loads. This defines optimization problems called respectively min-M, max-m and min-R. In the case where the graph of the network is a tree, it is known that the problem of building a valid configuration is polynomial. We show the three optimization variants have distinct properties regarding the theoretical complexity and the approximability. Particularly, we show that min-M is polynomial, that max-m is NP-Hard but belongs to the class FPTAS and that min-R is NP-Hard, cannot 1 be approximated to within any exponential relative ratio but, for any $ε$ > 0, there exists an algorithm for which the value of the returned solution equals the value of an optimal solution shifted by at most $ε$.

description: The fate of massive stars up to 300 Msun is highly uncertain. Do these objects produce pair-instability explosions, or normal Type Ic supernovae? In order to address these questions, we need to know their mass-loss rates during their lives. Here we present mass-loss predictions for very massive stars (VMS) in the range of 60-300 Msun. We use a novel method that simultaneously predicts the wind terminal velocities (vinf) and mass-loss rate (dM/dt) as a function of the stellar parameters: (i) luminosity/mass Gamma, (ii) metallicity Z, and (iii) effective temperature Teff. Using our results, we evaluate the likely outcomes for the most massive stars.

description: The Bethe-Salpeter approach allows for quantum-field-theoretic descriptions of relativistic bound states; its inherent complexity, however, usually prevents to find its exact solutions. Under suitable simplifying assumptions about the systems discussed, we derive analytically some examples of rigorous solutions to the instantaneous homogeneous Bethe-Salpeter equation by relating tentative solutions to the interactions responsible for the formation of bound states.

description: We report the results of optical monitoring for a sample of 11 blazars including 10 BL Lacs and 1 Flat Spectrum Radio Quasar (FSRQ). We have measured the multiband optical flux and colour variations in these blazars on intra-day and short-term timescales of months and have limited data for 2 more blazars. These photometric observations were made during 2009 to 2011, using six optical telescopes, four in Bulgaria, one in Greece and one in India. On short-term timescales we found significant flux variations in 9 of the sources and colour variations in 3 of them. Intra-day variability was detected on 6 nights for 2 sources out of the 18 nights and 4 sources for which we collected such data. These new optical observations of these blazars plus data from our previous published papers (for 3 more blazars) were used to analyze their spectral flux distributions in the optical frequency range. Our full sample for this purpose includes 6 high-synchrotron-frequency-peaked BL Lacs (HSPs), 3 intermediate-synchrotron-frequency-peaked BL Lacs (ISPs) and 6 low-synchrotron-frequency-peaked BL Lacs (LSPs; including both BL Lacs and FSRQs). We also investigated the spectral slope variability and found that the average spectral slopes of LSPs show a good accordance with the Synchrotron Self-Compton (SSC) loss dominated model. Our analysis supports previous studies that found that the spectra of the HSPs and FSRQs have significant additional emission components. The spectra of all these HSPs and LSPs get flatter when they become brighter, while for FSRQs the opposite appears to hold. This supports the hypothesis that there is a significant thermal contribution to the optical spectrum for FSRQs.

description: The nucleus of comet 67P/Churyumov-Gerasimenko exhibits a broad spectral reflectance feature around 3.2 $μ$m, which is omnipresent in all spectra of the surface, and whose attribution has remained elusive since its discovery. Based on laboratory experiments, we have shown that most of this absorption feature is due to ammonium (NH4+) salts mixed with the dark surface material. The depth of the band is compatible with semi-volatile ammonium salts being a major reservoir of nitrogen in the comet, which could dominate over refractory organic matter and volatile species. These salts may thus represent the long-sought reservoir of nitrogen in comets, possibly bringing their nitrogen-to-carbon ratio in agreement with the solar value. Moreover, the reflectance spectra of several asteroids are compatible with the presence of NH4+ salts at their surfaces. The presence of such salts, and other NH4+-bearing compounds on asteroids, comets, and possibly in proto-stellar environments, suggests that NH4+ may be a tracer of the incorporation and transformation of nitrogen in ices, minerals and organics, at different phases of the formation of the Solar System.

description: We apply an invariant-based inverse engineering method to control by time-dependent electric fields electron spin dynamics in a quantum dot with spin-orbit coupling in a weak magnetic field. The designed electric fields provide a shortcut to adiabatic processes that flips the spin rapidly, thus avoiding decoherence effects. This approach, being robust with respect to the device-dependent noise, can open new possibilities for the spin-based quantum information processing.

A Better Understanding of the Performance of Rate-1/2 Binary Turbo Codes that Use Odd-Even Interleavers

description: The effects of the odd-even constraint - as an interleaver design criterion - on the performance of rate-1/2 binary turbo codes are revisited. According to the current understanding, its adoption is favored because it makes the information bits be uniformly protected, each one by its own parity bit. In this paper, we provide instances that contradict this point of view suggesting for a different explanation of the constraint's behavior, in terms of distance spectrum.
Nanoswimmers in a ratchet potential: Effects of a transverse rocking force

description: We study the dynamics of a chemical nanoswimmer in a ratchet potential, which is periodically rocked in the transverse direction. As a result of the mechanochemical coupling, the self-propulsion velocity becomes force-dependent and particle trajectories are rectified in the direction of the ratchet modulation. The magnitude and direction of the nanoswimmer mean velocity depend upon both the rocking amplitude and the frequency. Remarkably, for frequencies larger than the inverse correlation time of the rotational diffusion, the velocity exhibits oscillatory behaviour as a function of the amplitude and the frequency with multiple reversals of the sign. These findings suggest that mechanochemical coupling can be utilized for controlling the motion of chemically active particles at the nanoscale.

The distribution of faint satellites around central galaxies in the CFHT Legacy Survey

description: We investigate the radial number density profile and the abundance distribution of faint satellites around central galaxies in the low redshift universe using the CFHT Legacy Survey. We consider three samples of central galaxies with magnitudes of M_r=-21, -22, and -23 selected from the Sloan Digital Sky Survey (SDSS) group catalog of Yang et al.. The satellite distribution around these central galaxies is obtained by cross-correlating these galaxies with the photometric catalogue of the CFHT Legacy Survey. The projected radial number density of the satellites obeys a power law form with the best-fit logarithmic slope of -1.05, independent of both the central galaxy luminosity and the satellite luminosity. The projected cross correlation function between central and satellite galaxies exhibits a non-monotonic trend with satellite luminosity. It is most pronounced for central galaxies with M_r=-21, where the decreasing trend of clustering amplitude with satellite luminosity is reversed when satellites are fainter than central galaxies by more than 2 magnitudes. A comparison with the satellite luminosity functions in the Milky Way and M31 shows that the Milky Way/M31 system has about twice as many satellites as around a typical central galaxy of similar luminosity. The implications for theoretical models are briefly discussed.

description: Hypothesis: Slippery Omniphobic Covalently Attached Liquids (SOCAL) have been proposed for making omnirepellent thin films of self-assembled dimethylsiloxane polymer brushes grafted from silica surfaces. Smooth and flat at very small scale, these fluid surfaces could exhibit a more complex multiscale structure though showing very weak contact angle hysteresis (less than 5{\textdegree}).Experiment: In this work, coatings were deposited on glass surfaces from an acidic dimethoxydimethylsilane solution under carefully controlled relative humidity. Ellipsometry mapping was used to analyze the surface structuration with nanometric thickness sensitivity. The sliding properties were determined using a drop shape analyzer with a tilting device, and chemical analyses of the coatings were performed using on-surface techniques (XPS, ATR-FTIR spectroscopy).Findings: Coated materials possessed an unexpected surface structure with multiscale semispherical-like features, which surprisingly, did not increase the contact angle hysteresis. A careful study of some parameters of the coating process and the related evolution of the surface properties allowed us to propose a new model of the chemical organization of the polymer to support this remarkable liquid-like behavior. These structures are made of end-grafted strongly adsorbed Guiselin brushes with humidity-dependent thickness: the higher the humidity, the thinner and the more slippery the coating.

description: Urlatori alla sbarra (Lucio Fulci, 1960), I ragazzi del juke-box (Lucio Fulci, 1962) e La battaglia dei Mods (Franco Montemurro, 1966) sono tre esempi di film musicali italiani realizzati durante gli anni Sessanta (il genere cosiddetto ‘musicarello’), che mostra l’impatto crescente delle sottoculture giovanili.
Concentrandoci su questi film, che esibiscono la musica rock e pop, le feste e il ballo, è possibile riscontrare numerosi riferimenti ai beni di consumo e ai prodotti del miracolo economico italiano degli anni Sessanta, come i juke-box, i famosi veicoli made in Italy e la moda.
La gioventù che fa da protagonista in questi film era ispirata ad una cultura anglo-americana contaminata; al contempo, la risposta autoctona all’influenza della musica britannica e statunitense era un’entità culturale ibrida, che combinava coreografie yé-yé alla rivoluzione di una società transnazionale e ‘dissoluta’.
