description: Detailed models of the explosion of a white dwarf, which include self-consistent calculations of the light curve and spectra, provide a link between observational quantities and the underlying explosion.These calculations assume spherical geometry and are based on parameterized descriptions of the burning front during the deflagration phase. Recently, first multi-dimensional calculations for nuclear burning fronts have been performed. Although a fully consistent treatment of the burning fronts is beyond the current state of the art, these calculations provided a new and better understanding of the physics, and new descriptions for the flame propagation have been proposed. Here, we have studied the influence on the results of previous analyses of Type Ia Supernovae, namely, the nucleosynthesis and structure of the expanding envelope. Our calculations are based on a set of delayed detonation models with parameters that give a good account of the optical and infrared light curves, and of the spectral evolution. In this scenario, the burning front propagates first in a deflagration mode and, subsequently, turns into a detonation. The explosions and light curves are calculated using a one-dimensional Lagrangian radiation-hydro code, including a detailed nuclear network.

description: It is usually assumed that the production of baryons in $B$ meson decays is induced primarily by the quark level process $b\to c\bar ud$, where the charm quark hadronizes into a charmed baryon. With this assumption, the $Λ_c$ momentum spectrum would indicate that the transition $B\toΛ_c X$ is dominated by multi-body $B$ decays. However, a closer examination of the momentum spectrum reveals that the mass $m_X$ against which the $Λ_c$ is recoiling almost always satisfies $m_X\agt m_{Ξ_c}$. This fact leads us to examine the hypothesis that the production of charmed baryons in $B$ decays is in fact dominated by the underlying transition $b\to c\bar cs$, and is seen primarily in modes with two charmed baryons in the final state. We propose a number of tests of this hypothesis. If this mechanism is indeed important in baryon production, then there are interesting consequences and applications, including potentially important implications for the ``charm deficit'' in $B$ decays.

description: We present 20 years of radial velocity (RV) measurements of the M1 dwarf Gl15A, combining 5 years of intensive RV monitoring with the HARPS-N spectrograph with 15 years of archival HIRES/Keck RV data. We carry out an MCMC-based analysis of the RV time series, inclusive of Gaussian Process (GP) approach to the description of stellar activity induced RV variations. Our analysis confirms the Keplerian nature and refines the orbital solution for the 11.44-day period super Earth, Gl15A\,b, reducing its amplitude to $1.68^{+0.17}_{-0.18}$ m s$^{-1}$ ($M \sin i = 3.03^{+0.46}_{-0.44}$ M$_\oplus$), and successfully models a long-term trend in the combined RV dataset in terms of a Keplerian orbit with a period around 7600 days and an amplitude of $2.5^{+1.3}_{-1.0}$ m s$^{-1}$, corresponding to a super-Neptune mass ($M \sin i = 36^{+25}_{-18}$ M$_\oplus$) planetary companion. We also discuss the present orbital configuration of Gl15A planetary system in terms of the possible outcomes of Lidov-Kozai interactions with the wide-separation companion Gl15B in a suite of detailed numerical simulations. In order to improve the results of the dynamical analysis, we derive a new orbital solution for the binary system, combining our RV measurements with astrometric data from the WDS catalogue. The eccentric Lidov-Kozai analysis shows the strong influence of Gl15B on the Gl15A planetary system, which can produce orbits compatible with the observed configuration for initial inclinations of the planetary system between $75^\circ$ and $90^\circ$, and can also enhance the eccentricity of the outer planet well above the observed value, even resulting in orbital instability, for inclinations around $0^\circ$ and $15^\circ - 30^\circ$. The Gl15A system is the multi-planet system closest to Earth, at $3.57$ pc, and hosts the longest period RV sub-jovian mass planet discovered so far.

description: Let $Γ$ be a countable Abelian group and $f \in \Z[Γ]$, where $\Z[Γ]$ denotes the integral group ring of $Γ$. Consider the Pontryagin dual $X_f$ of the cyclic $\Z[Γ]$-module $\Z[Γ]/\Z[Γ] f$ and suppose that $f$ is weakly expansive (e.g., $f$ is invertible in $\ell^1(Γ)$, or, when $Γ$ is not virtually $\Z$ or $\Z^2$, $f$ is well-balanced) and that $X_f$ is connected. We prove that if $τ\colon X_f \to X_f$ is a $Γ$-equivariant continuous map, then $τ$ is surjective if and only if the restriction of $τ$ to each $Γ$-homoclinicity class is injective. We also show that this equivalence remains valid in the case when $Γ= \Z^d$ and $f \in \Z[Γ] = \Z[u_1,u_1^{-1}, \ldots, u_d, u_d^{-1}]$ is an irreducible atoral polynomial such that its zero-set $Z(f)$ is contained in the image of the intersection of $[0,1]^d$ and a finite union of hyperplanes in $\R^d$ under the quotient map $\R^d \to \T^d$ (e.g., when $d \geq 2$ such that $Z(f)$ is finite). These two results are analogues of the classical Garden of Eden theorem of Moore and Myhill for cellular automata with finite alphabet over $Γ$.

description: The UV emission lines of Hercules X-1, resolved with the HST GHRS and STIS, can be divided into broad (FWHM 750 km/s) and narrow (FWHM 150 km/s) components. The broad lines can be unambiguously identified with emission from an accretion disk which rotates prograde with the orbit. The narrow lines, previously identified with the X-ray illuminated atmosphere of the companion star, are blueshifted at both phi=0.2 and phi=0.8 and the line flux at phi=0.2 is 0.2 of the flux at phi=0.8. Line ratio diagnostics show that the density of the narrow line region is log n=13.4+/-0.2 and the temperature is T=1.0+/-0.2x10^5 K. The symmetry of the eclipse ingress suggests that the line emission on the surface of the disk is left-right symmetric relative to the orbit. Model fits to the O V, Si IV, and He II line profiles agree with this result, but fits to the N V lines suggest that the receding side of the disk is brighter. We note that there are narrow absorption components in the N V lines with blueshifts of 500 km/s.

description: Molecular oxygen has been detected in the coma of comet 67P/Churyumov--Gerasimenko with a mean abundance of 3.80 $\pm$ 0.85\% by the ROSINA mass spectrometer on board the Rosetta spacecraft. To account for the presence of this species in comet 67P/Churyumov--Gerasimenko, it has been shown that the radiolysis of ice grains precursors of comets is a viable mechanism in low-density environments, such as molecular clouds. Here, we investigate the alternative possibility that the icy grains present in the midplane of the protosolar nebula were irradiated during their vertical transport between the midplane and the upper layers over a large number of cycles, as a result of turbulent mixing. Consequently, these grains spent a non-negligible fraction of their lifetime in the disk's upper regions, where the irradiation by cosmic rays was strong. To do so, we used a coupled disk-transport-irradiation model to calculate the time evolution of the molecular oxygen abundance radiolytically produced in ice grains. Our computations show that, even if a significant fraction of the icy particles have followed a back and forth cycle towards the upper layers of the disk over 10 million of years, a timespan far exceeding the formation timescale of comet 67P/Churyumov--Gerasimenko, the amount of produced molecular oxygen is at least two orders of magnitude lower than the Rosetta observations. We conclude that the most likely scenario remains the formation of molecular oxygen in low-density environments, such as the presolar cloud, prior to the genesis of the protosolar nebula.

description: Primary human hepatocytes (PHHs) remain the gold standard for in vitro investigations of xenobiotic metabolism and hepatotoxicity. However, scarcity of liver tissue and novel developments in liver surgery has limited the availability and quality of tissue samples. In particular, warm ischemia shifts the intracellular metabolism from aerobic to anaerobic conditions, which increases glycogenolysis, glucose depletion and energy deficiency. Therefore, the aim of the present study was to investigate whether supplementation with glucose and insulin during PHH isolation could reconstitute intracellular glycogen storage and beneficially affect viability and functionality. Furthermore, the study elucidated whether the susceptibility of the tissue’s energy status correlates with body mass index (BMI). PHHs from 12 donors were isolated from human liver tissue obtained from partial liver resections using a two-step EDTA/collagenase perfusion technique. For a direct comparison of the influence of glucose/insulin supplementation, we modified the setup, enabling the parallel isolation of two pieces of one tissue sample with varying perfusate. Independent of the BMI of the patient, the glycogen content in liver tissue was notably low in the majority of samples. Furthermore, supplementation with glucose and insulin had no beneficial effect on the glycogen concentration of isolated PHHs. However, an indirect improvement of the availability of energy was shown by increased viability, plating efficiency and partial cellular activity after supplementation. The plating efficiency showed a striking inverse correlation with increasing lipid content of PHHs. However, 60 h of cultivation time revealed no significant impact on the maintenance of albumin and urea synthesis or xenobiotic metabolism after supplementation. In conclusion, surgical procedures and tissue handling may decrease hepatic energy resources and lead to cell stress and death. Consequently, PHHs with low energy resources die during the isolation process without supplementation of glucose/insulin or early cell culture, while their survival rates are improved with glucose/insulin supplementation.

description: Leisure is a context for both risk and protection of adolescent well-being. Using a person-centered analysis, the present study examined the links between after-school time use and the adjustment of an urban sample of 7th–12th graders (n = 3,808), who self-reported on their leisure activities, school achievement, problem behaviors, and happiness. Results indicated that time use patterns were distributed in five clusters: Creative/Social, Productive/Home, High-Social/Sports, Uninvolved/Sports, and Uninvolved/Home. These patterns of time use varied by age, gender and SES, and were linked with adolescent outcomes in a way that adolescents involved with multiple constructive activities presented better adjustment compared with their either uninvolved or socially oriented counterparts. Specific groups of adolescents were at higher risk for problem behaviors linked to after-school time use. These findings have relevant implications for evidence-based interventions and policies aiming at promoting adolescent well-being and targeting at-risk populations of youth.

Perturbative QCD Fragmentation Functions for Production of P-wave Mesons with Charm and Beauty
Creators: name: Yuan, Tzu Chiang
Publisher: name: arXiv
Year: 1994
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We calculate the leading order QCD fragmentation functions for the production of $P$-wave charmed beauty mesons. Long-distance effects are factored into two nonperturbative parameters: the derivative of the radial wavefunction at the origin and a second parameter related to the probability for a $(\bar b c)$ heavy quark pair that is produced in a color-octet $S$-wave state to form a color-singlet $P$-wave bound state. The four $2P$ states and those $3P$ states which lie below the $BD$ flavor threshold eventually all decay into the $1S$ ground state $B_c$ through hadronic cascades or by emitting photons. The total fragmentation probabilities for production of the $1S$ ground state $B_c$ from the cascades of the $2P$ and $3P$ states are about $1.7 \times 10^{-4}$ and $2.3 \times 10^{-4}$ respectively. Thus the direct production of the $P$-wave states via fragmentation may account for a significant fraction of the inclusive production rate of the $B_c$ at large transverse momentum in high energy colliders. Our analytic results for the $P$-wave fragmentation functions disagree with those obtained earlier in the literature.

description: The semi-infinite XY spin chain with an impurity at the boundary has been chosen as a prototype of interacting many-body systems to test for non-ergodic behavior. The model is exactly solvable in analytic way in the thermodynamic limit, where energy eigenstates and the spectrum are obtained in closed form. In addition of a continuous band, localized states may split off from the continuum, for some values of the impurity parameters. In the next step, after the preparation of an arbitrary non-equilibrium state, we observe the time evolution of the site magnetization. Relaxation properties are described by the long-time behavior, which is estimated using the stationary phase method. Absence of localized states defines an ergodic region in parameter space, where the system relaxes to a homogeneous magnetization. Out of this region, impurity levels split from the band, and localization phenomena may lead to non-ergodicity.

description: HYDRA spectra of 287 stars in the field of NGC 2506 from the turnoff through the giant branch are analyzed. With previous data, 22 are identified as probable binaries; 90 more are classified as potential non-members. Spectroscopic analyses of ~60 red giants and slowly rotating turnoff stars using line equivalent widths and a neural network approach lead to [Fe/H] = -0.27 +/- 0.07 (s.d.) and [Fe/H] = -0.27 +/- 0.06 (s.d.), respectively. Li abundances are derived for 145 probable single-star members, 44 being upper limits. Among turnoff stars outside the Li-dip, A(Li) = 3.04 +/- 0.16 (s.d.), with no trend with color, luminosity, or rotation speed. Evolving from the turnoff across the subgiant branch, there is a well-delineated decline to A(Li) ~1.25 at the giant branch base, coupled with the rotational spindown from between ~20 and 70 km/s to less than 20 km/s for stars entering the subgiant branch and beyond. A(Li) remains effectively constant from the giant branch base to the red giant clump level. A new member above the clump redefines the path of the first-ascent red giant branch; its Li is 0.6 dex below the first-ascent red giants. With one exception, all post-He-flash stars have upper limits to A(Li), at or below the level of the brightest first-ascent red giant. The patterns are in excellent qualitative agreement with the model predictions for low/intermediate-mass stars which undergo rotation-induced mixing at the turnoff and subgiant branch, first dredge-up, and thermohaline mixing beyond the red giant bump.

description: We use a homogeneous sample of gamma-ray bursts (GRB) extracted from 5.9 years of BATSE DISCLA data (astro-ph/9908190) and a variety of broken power-law luminosity functions to derive GRB luminosities and space densities. Luminosity functions that are narrow or exhibit no density evolution produce expected redshift distributions that are incompatible with the observation of a GRB redshift of 3.4. For q_o=0.1 and density evolution rising to 10 at z=1, we find for a variety of slopes of the luminosity function values of the local space density around 0.18 Gpc^{-3} y^{-1} with a range of only 40%. Characteristic 50--300 keV peak luminosities exhibit a range of a factor of 6 around 6e51 erg/s corresponding to a characteristic total luminosity of 1.2e53 erg in the 10--1000 keV band. For q_o=0.5, densities are higher and luminosities lower, both by a factor of 2.5. The local emissivity of GRBs is 1.0e52 erg Gpc^{-3} y^{-1} in the 10--1000 keV band.

description: Abstract – Stemming from the need to combine teachers’ pedagogical-didactic and disciplinary competences, this paper presents the results of an experience aimed at creating a simplex teacher training model; this one has to be conceived as a possible operational guide to harmonize, through the declination in the didactic field of regulatory principles, the ontological identity of the disciplines and the emerging needs within the teaching-learning process. Riassunto – Il presente articolo, partendo dalla necessità di coniugare le competenze pedagogico-didattiche e le competenze disciplinari degli insegnanti, presenta i risultati di un’esperienza finalizzata alla realizzazione di una formazione docenti in chiave semplessa, da intendersi come possibile guida operativa per armonizzare, attraverso la declinazione in ambito didattico di principi regolatori, l’identità ontologica delle discipline e i bisogni emergenti nel processo di insegnamento-apprendimento. Keywords – general didactics, didactics of disciplines, simplexity, teacher education, competencies Parole chiave – didattica generale, didattica delle discipline, semplessità, formazione docenti, competenze

description: In this work we explore the effects of adopting initial mass functions (IMFs) variable in time on the chemical evolution of the Galaxy. In order to do that we adopt a chemical evolution model which assumes two main infall episodes for the formation of the Galaxy and which proved to be successful in reproducing the majority of the observational constraints, at least for the case of a constant IMF. Different variable IMFs are tested with this model, all assuming that massive stars are preferentially formed in ambients of low metallicity. This implies that massive stars are formed preferentially at early times and at large galactocentric distances. Our numerical results have shown that all the variable IMFs proposed so far are unable to reproduce all the relevant observational constraints in the Galaxy and that a constant IMF still reproduces better the observations. In particular, variable IMFs of the kind explored here are unable to reproduce the observed abundance gradients even when allowing for changes in other chemical evolution model parameters as, for instance, the star formation rate. As a consequence of this we conclude that the G-dwarf metallicity distribution is best explained by infall with a large timescale and a constant IMF, since it is possible to find variable IMFs of the kind studied here, reproducing the G-dwarf metallicity but this worsen the agreement with other observational constraints.

description: In this paper, we use Flaschka's change of variables of the open Toda lattice and its interpretation in term of the group structure of the LU factorisation as a coadjoint motion on a certain dual of Lie algebra to implement a structure preserving noise and dissipation. Both preserve the structure of coadjoint orbit, that is the space of symmetric tri-diagonal matrices and arise as a new type of multiplicative noise and nonlinear dissipation of the Toda lattice. We investigate some of the properties of these deformations and in particular the continuum limit as a stochastic Burger equation with a nonlinear viscosity. This work is meant to be exploratory, and open more questions that we can answer with simple mathematical tools and without numerical simulations.

description: We examine the contributions of Majorana neutrinos to CP-violating WWZ and ZZZ self-couplings, using a model in which sterile neutrinos couple to the W and Z by mixing with a fourth-generation heavy lepton. We find that the induced form factors can be as large as 0.5%. The model satisfies all phenomenological bounds in a natural way, including those due to the strong limits on the neutron and electron electric dipole moments. Anomalous CP-odd couplings of this size are unlikely to be observed at LEP200, but might be detectable at NLC.

description: Abstract – Didactics of the implicit is a research frontier opened ten years ago to explore the knowledge of teaching practice from which to build a theory of teaching practice useful also for the design of avant-garde training models. The model of collaborative research-training, based on the analysis of educational practices and descending from the paradigm of didactics of the implicit, allows to re-theorise teaching by enhancing the knowledge of practitioners and to question the current models of training, today built “in alternation” between theory and practice, with a clear predominance of theory over practice. Teacher training through research makes it possible to overcome the historical hierarchical distinction between researchers in didactics and teachers in schools. It is a frontier of University-School work in which the teacher takes on the role of an active research partner. The paper presents a paradigmatic example of an approach to teacher professional development: the DidaSco Project, active since 2010 at the University of Bari Aldo Moro. Riassunto – La didattica dell’implicito è una frontiera della ricerca aperta dieci anni fa per esplorare i saperi della pratica insegnante a partire dai quali costruire una teoria della pratica insegnante utile anche per il disegno di modellistiche formative di avanguardia. Il modello della ricerca-formazione collaborativa, basato sull’analisi delle pratiche educative e discendente dal paradigma della didattica dell’implicito, consente di ri-teorizzare l’insegnamento valorizzando il sapere dei pratici e di mettere in discussione i modelli attuali di formazione, oggi costruiti “in alternanza” fra teoria e pratica, con una predominanza netta della teoria sulla pratica. La formazione insegnante attraverso la ricerca consente di superare la storica distinzione gerarchica fra ricercatori di Didattica e insegnanti delle Scuole. Si tratta di una frontiera di lavoro Università-Scuola in cui l'insegnante assumere il ruolo di partner attivo della ricerca. Il contributo presenta un esempio paradigmatico di approccio per lo sviluppo professionale dell'insegnante: il DidaSco Project, attivo dal 2010 presso l'Università degli Studi di Bari Aldo Moro.

Spin-vorticity coupling in viscous electron fluids

description: We consider spin-vorticity coupling - the generation of spin polarization by vorticity - in viscous two-dimensional electron systems with spin-orbit coupling. We first derive hydrodynamic equations for spin and momentum densities in which their mutual coupling is determined by the rotational viscosity. We then calculate the rotational viscosity microscopically in the limits of weak and strong spin-orbit coupling. We provide estimates that show that the spin-orbit coupling achieved in recent experiments is strong enough for the spin-vorticity coupling to be observed. On the one hand, this coupling provides a way to image viscous electron flows by imaging spin densities. On the other hand, we show that the spin polarization generated by spin-vorticity coupling in the hydrodynamic regime can, in principle, be much larger than that generated, e.g. by the spin Hall effect, in the diffusive regime.

description: Abstract –This article explores the epistemological and methodological implications of the transformative approach to teacher professional development, highlighting its connections with collaborative research and practice-based studies. The hypothesis of a construction of meaningful knowledge with (not on) the teachers is supported, emerging from the comparison with the real problems of school life and capable of coping with the complexity and mutability characterizing the current crisis scenarios and change of educational contexts. Adopting a practice-based perspective of transformative learning to promote trajectories of professional development implies the activation of cycles of action, dialogue, and reflection through collective and collaborative inquiry processes that know how to connect theory and practice, research and participation, rigor and relevance, conceptual coherence and impact. Two examples are presented that are useful for understanding the methodological implications of this approach, with particular reference to the technique of metaphors analysis and the protocol of action learning conversation. Riassunto – L’articolo esplora le implicazioni epistemologiche e metodologiche dell'approccio trasformativo allo sviluppo professionale dell’insegnante, evidenziandone le connessioni con la ricerca collaborativa e con gli studi practice-based. È sostenuta l’ipotesi di una costruzione di conoscenze significative con (non su) i/le docenti, emergenti dal confronto con i problemi reali della vita scolastica e capaci di far fronte alla complessità e alla mutevolezza caratterizzanti gli attuali scenari di crisi e cambiamento dei contesti educativi. Adottare una prospettiva practice-based dell’apprendimento trasformativo per promuovere traiettorie di sviluppo professionale implica l’attivazione di cicli di azione, dialogo e riflessione attraverso processi di inquiry collettivi e collaborativi che sappiano coniugare teoria e pratica, ricerca e partecipazione, rigore e rilevanza, coerenza concettuale e impatto. Sono presentati due esempi utili a comprendere le ricadute metodologiche di tale approccio, con particolare riferimento alla tecnica di analisi delle metafore e al protocollo dell’action learning conversation.

description: We present analytic solutions to the spatially homogeneous axion field equation, using a model potential which strongly resembles the standard anharmonic $(1-\cos Nθ)$ potential, but contains only a piece-wise second order term. Our exactly soluble model for $θ(t)$ spans the entire range $[-π/N,π/N]$. In particular, we are able to confirm (i) Turner's numeric correction factors \cite{Turner} to the adiabatic and harmonic analytic treatments of homogeneous axion oscillations, and (ii) Lyth's estimate \cite{Lyth} valid near the metastable misalignment angle $π/N$ at the peak of the potential. We compute the enhancement of axion density fluctuations that occurs when the axion mass becomes significant at $T\sim 1$ GeV. We find that the anharmonicity amplifies density \mbox{f}luctuations, but only significantly for relatively large initial misalignment angles. The enhancement factor is $\sim$ (2,3,4,13) for $θ_{\rm in}\sim (0.85,0.90,0.95,0.99)\timesπ$.

Modeling neutrino-induced charged pion production on water at T2K kinematics

description: Pion production is a significant component of the signal in accelerator-based neutrino experiments. Over the last years, the MiniBooNE, T2K and MINERvA collaborations have reported a substantial amount of data on (anti)neutrino-induced pion production on the nucleus. However, a comprehensive and consistent description of the whole data set is still missing. We aim at improving the current understanding of neutrino-induced pion production on the nucleus. To this end, the comparison of experimental data with theoretical predictions, preferably based on microscopic models, is essential to disentangle the different reaction mechanisms involved in the process. To describe single-pion production (SPP) we use a hybrid model that combines a low- and a high-energy approach. The low-energy model (LEM) contains resonances and background terms. At high invariant masses, a high-energy model based on a Regge approach is employed. The model is implemented in the nucleus using the relativistic plane wave impulse approximation (RPWIA). We present a comparison of the hybrid-RPWIA and LEM with the recent neutrino-induced charged current $1π^+$ production cross section on water reported by T2K. In order to judge the impact of final-state interactions (FSI) we confront our results with those of the NuWro Monte Carlo generator. The hybrid-RPWIA model and NuWro compare favorably to the data, albeit that FSI are not included in the former. These results complement our previous work [Phys. Rev. D 97, 013004 (2018)] where we compared the models to the MINERvA and MiniBooNE $1π^+$ data. The hybrid-RPWIA model tends to overpredict both the T2K and MINERvA data in kinematic regions where the largest suppression due to FSI is expected, and agrees remarkably well with the data in other kinematic regions. On the contrary, the MiniBooNE data is underpredicted over the whole kinematic range.

description: In this paper we develop algorithms of finding homogeneous spaces of semisimple non-compact Lie groups which do not admit compact Clifford-Klein forms. We propose a computer program which checks if the given homogeneous space has a non-vanishing cohomological obstruction (found by Tholozan) to compact Clifford-Klein forms. By a numerical experiment we show that there is a large class of homogeneous spaces satisfying Tholozan's condition.
