description: We study dynamic field theories for nonconserving $N$-vector models that are subject to spatial-anisotropic bias perturbations. We first investigate the conditions under which these field theories can have a single length scale. When N=2 or $N \ge 4$, it turns out that there are no such field theories, and, hence, the corresponding models are pushed by the bias into the Ising class. We further construct nontrivial field theories for N=3 case with certain bias perturbations and analyze the renormalization-group flow equations. We find that the three-component systems can exhibit rich critical behavior belonging to two different universality classes.

Simulando un processo di interazione mareale stretto fra una stella e i corpi solidi che le orbitano attorno (asteroidi, comete o pianeti), gli astronomi Zhang e Lin sono riusciti a simulare la formazione di oggetti molto allungati, dalle proprietà simili a quelle di 'Oumuamua. La "produzione" di sigari interstellari potrebbe essere un processo comune nella Via Lattea e – in questo quadro – una frazione dei corpi simili ad 'Oumuamua sono potenziali candidati a essere vettori di una panspermia interstellare

description: L’éducation nutritionnelle fait partie du domaine « Corps et mouvement » du Plan d’études romand et il est vivement recommandé de l’enseigner durant toute la scolarité. En effet, selon l’Organisation mondiale de la Santé, une alimentation saine et équilibrée est primordiale pour la santé physique et psychique d’un individu. Malgré son importance vitale, ce sujet nous semble peu abordé en classe. Par ce travail de mémoire, nous souhaitions tout d’abord faire un état de lieux des connaissances et pratiques des enseignant-es du cycle 1 au sujet de l’éducation nutritionnelle par le biais d’entretiens semi-directifs. Pour enrichir notre recherche, nous avons mené une seconde étude durant laquelle nous avons partagé notre expérience personnelle lors de la mise en place d’une séquence didactique issue de « En forme et en santé, avec le disque de l’alimentation pour enfants » proposée par la Société Suisse de Nutrition dans nos classes de 1-2P et 3P. Cette seconde étude nous a permis de vivre les points forts et les difficultés d’une sensibilisation à une alimentation saine et équilibrée mais elle nous a également donné l’opportunité d’observer les réactions des élèves. Par nos résultats, nous avons pu effectuer quelques constats sur les aspects positifs et négatifs de l’éducation nutritionnelle, autant du point de vue des enseignant- es que des élèves. Nous avons notamment pu constater un réel plaisir pour les élèves d’apprendre sur le sujet. Malgré l’acquisition de nouvelles connaissances lors de la séquence, nous n’avons cependant pas observé de changements dans leurs choix de collation. Pour conclure notre travail, suite à nos résultats, nous avons établi un guide des bonnes pratiques permettant aux enseignant-es de se lancer positivement et sereinement dans l’éducation nutritionnelle au cycle 1.

Polytropic neutron star - black hole merger simulations with a Paczynski-Wiita potential
Creators: name: Ruffert, M.

Year: 2009
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Context: Mergers of neutron stars (NS) and black holes (BH) are among the strongest sources of gravitational waves and are potential central engines for short gamma-ray bursts. Aims: We aim to compare the general relativistic (GR) results by other groups with Newtonian calculations of models with equivalent parameters. We vary the mass ratios between NS and BH and the compactness of the NS. The mass of the NS is 1.4 M_sol. We compare the dynamics in the parameter-space regions where the NS is expected to reach the innermost stable circular orbit (ISCO) before being tidally disrupted (mass shedding, MS) and vice versa. Methods: The hydrodynamics is evolved by a Newtonian PPM scheme with four levels of nested grids. We use a polytropic EoS (Gamma=2), as was done in the GR simulations. However, instead of full GR we use a Newtonian potential supplemented by a Paczynski-Wiita-Artemova potential for the BH, both disregarding and including rotation of the BH. Results: If the NS is compact (C=0.18) it is accreted by the BH more quickly, and only a small amount of mass remains outside the BH. If the mass ratio is small (Q=2 or 3) or the NS is less compact (C=0.16 or less) the NS is tidally torn apart before being accreted. Although most of the mass is absorbed by the BH, some 0.1 M_sol remain in a tidal arm. For small mass ratios the tidal arm can wrap around the BH to form a thick disk. When including the effects of BH spin-up or spin-down by the accreted matter, more mass remains in the surroundings (0.2-0.3 M_sol). Conclusions: Although details and quantitative results differ, the general trends of our Newtonian calculations are similar to the GR calculations. A clear delimiting line that separates ISCO from the MS cases is not found. Inclusion of BH rotation as well as sufficient numerical resolution are extremely important.

An analysis of the Fraser River tidal control
Creators: name: Kay, Donald Hughie James
Publisher: name: University of British Columbia
Year: 2012

description: The development of an automatic control system involves a consideration of the problems of the stability and response of such a system. The purpose of this thesis is to outline these problems as they appear in the automatic control of water level in a tidal basin model. A synopsis of general servomechanism theory is briefly outlined stressing three points (1) Design the system so that oscillatory conditions prevail. (2) Design the natural frequency well above the operating frequency. (3) Where necessary introduce stabilizing networks. The results obtained by tests revealed one thing; the introduction of external circuits had very little effect on the continuous operation of the tidal model. An examination of the theoretical analysis of the control system however brought out three reasons for limiting the value of the constant K₄. The constant K₄ corresponds to the moment of inertia of a mechanical system. The constant K₄ is related to the parameters of the system, which are the area of the basin, the length of the weirs, and the pump discharge.

description: Operating quantum sensors and quantum computers would make data in the form of quantum states available for purely quantum processing, opening new avenues for studying physical processes and certifying quantum technologies. In this Perspective, we review a line of works dealing with measurements that reveal structural properties of quantum datasets given in the form of product states. These algorithms are universal, meaning that their performances do not depend on the reference frame in which the dataset is provided. Requiring the universality property implies a characterization of optimal measurements via group representation theory.

description: The state space of a machine admits the structure of time. For example, the geometric realization of a precubical set, a generalization of an unlabeled asynchronous transition system, admits a "local preorder" encoding control flow. In the case where time does not loop, the "locally preordered" state space splits into causally distinct components. The set of such components often gives a computable invariant of machine behavior. In the general case, no such meaningful partition could exist. However, as we show in this note, the locally preordered geometric realization of a precubical set admits a "locally monotone" covering from a state space in which time does not loop. Thus we hope to extend geometric techniques in static program analysis to looping processes.

description: We study the nature of rapidly star-forming galaxies at z=2 in cosmological hydrodynamic simulations, and compare their properties to observations of sub-millimetre galaxies (SMGs). We identify simulated SMGs as the most rapidly star-forming systems that match the observed number density of SMGs. In our models, SMGs are massive galaxies sitting at the centres of large potential wells, being fed by smooth infall and gas-rich satellites at rates comparable to their star formation rates (SFR). They are not typically undergoing major mergers that significantly boost their quiescent SFR, but they still often show complex gas morphologies and kinematics. Our simulated SMGs have stellar masses of log M*/Mo~11-11.7, SFRs of ~180-500 Mo/yr, a clustering length of 10 Mpc/h, and solar metallicities. The SFRs are lower than those inferred from far-IR data by a factor of 3, which we suggest may owe to one or more systematic effects in the SFR calibrations. SMGs at z=2 live in ~10^13 Mo halos, and by z=0 they mostly end up as brightest group galaxies in ~10^14 Mo halos. We predict that higher-M* SMGs should have on average lower specific SFRs, less disturbed morphologies, and higher clustering. We also predict that deeper far-IR surveys will smoothly join SMGs onto the massive end of the SFR-M* relationship defined by lower-mass z=2 galaxies. Overall, our simulated rapid star-formers provide as good a match to available SMG data as merger-based scenarios, offering an alternative scenario that emerges naturally from cosmological simulations.

Entanglement in Massive Coupled Oscillators

Year: 2009

description: This article investigates entanglement of the motional states of massive coupled oscillators. The specific realization of an idealized diatomic molecule in one-dimension is considered, but the techniques developed apply to any massive particles with two degrees of freedom and a quadratic Hamiltonian. We present two methods, one analytic and one approximate, to calculate the interatomic entanglement for Gaussian and non-Gaussian pure states as measured by the purity of the reduced density matrix. The cases of free and trapped molecules and hetero- and homonuclear molecules are treated. In general, when the trap frequency and the molecular frequency are very different, and when the atomic masses are equal, the atoms are highly-entangled for molecular coherent states and number states. Surprisingly, while the interatomic entanglement can be quite large even for molecular coherent states, the covariance of atomic position and momentum observables can be entirely explained by a classical model with appropriately chosen statistical uncertainty.

description: En tant que futures enseignantes, nous avons choisi de construire notre projet de recherche sur les activités plurilingues et pluriculturelles dans l’enseignement du français. Les lectures effectuées nous ont permis de constater que la prise en compte du bagage linguistique et culturel des élèves dans l’enseignement est un avantage pour les apprentissages. De plus, nous avons pu remarquer dans notre pratique que l’orthographe de la langue française est une difficulté courante chez les jeunes élèves. C’est pourquoi, nous avons décidé de nous concentrer particulièrement sur l’accord du pluriel dans le groupe nominal, dans un enseignement qui prend en compte des approches plurilingues. Ce travail de mémoire a pour but de démontrer, d’une part que la comparaison des langues va permettre de montrer que la notion du pluriel diffère selon les langues. D’autre part, ces comparaisons avec le français permettent de voir les différentes marques du pluriel dans diverses langues. Ceci permet de mettre en évidence et de comprendre le fonctionnement du français dans l’accord du groupe nominal. Afin de mener à bien les objectifs susmentionnés, nous avons mis en place une méthode quasi-expérimentale constituée d’une classe expérimentale et d’une classe contrôle. Nous avons également construit un dispositif d’enseignement. Les deux classes ont réalisé un prétest et la classe expérimentale a bénéficié d’un module de la séquence d’activités plurilingues autour de la notion du pluriel dans le groupe nominal. Deux professionnelles de l’enseignement ont répondu à des questionnaires afin de nous faire part de la fiabilité de notre séquence. Les prétests, la réalisation du module ainsi que les avis des enseignantes nous ont permis d’aboutir à des résultats encourageants et novateurs au sujet de l’accord du pluriel dans le groupe nominal avec un enseignement qui prend en compte des approches plurilingues. Démontrer la pertinence de la prise en compte du bagage culturel des élèves nous permettra d’utiliser ces approches comme un outil d’enseignement non négligeable.

Uno fra i pilastri della cosmologia è che, su distanze sufficientemente grandi, l’universo appare uguale in tutte le direzioni. È la cosiddetta isotropia. Analizzando oltre trecento ammassi di galassie con Chandra e Xmm-Newton, però, un team di astrofisici mette in dubbio questa uniformità: in alcune direzioni l’universo parrebbe espandersi a velocità diversa rispetto ad altre. Ne parliamo con uno dei coautori, Lorenzo Lovisari, da poco rientrato da Harvard per lavorare all’Inaf di Bologna

Noise figure of the transistor amplifier
Creators: name: Hatton, Walter Lewis
Publisher: name: University of British Columbia
Year: 2012

description: The noise figure of the transistor amplifier is of special interest since the large quantity of excess noise present limits the usefulness of the transistor as a low-noise amplifier. While the equivalent noise voltages generated in the emitter and collector leads vary inversely with frequency, the noise figure does not. This variation from the inverse frequency characteristic is produced by the decrease of the effective gain at higher frequencies. The subject of this thesis is the investigation of this variation. The variation of the noise figure with frequency has been measured for several different transistors, with varying emitter and collector currents. Equivalent diagrams have been suggested which explain the variation of the noise figure with frequency if transit time dispersion is negligible. For low frequencies, the noise figure is given by, (Formula omitted) Variation of the noise figure due to the stray capacities is given approximately by (Formula omitted) The variation, due to transit time effects , ignoring transit time dispersion , i s (Formula omitted) The operating conditions for minimum noise figure of the transistor amplifier are dependent on the frequency. At low frequencies, a low value of emitter current should be used, and the lowest possible value of collector voltage which is compatible with the desired gain. At higher frequencies a low value of emitter current should also be used but the value of the collector voltage is determined by the frequency. The higher the frequency, the higher will be the required collector voltage. The best noise figures at higher frequencies will be obtained with transistors with the following characteristics: (i) ʳm large (ii) close spacing of point contacts (iii) high value of resistivity (iv) small transit time dispersion. Equivalent diagrams have been suggested which parially account for the variation of the noise figure with frequency. It has been suggested that transit time dispersion would explain the remaining deviation of the noise figure from the inverse frequency characteristic.

description: In the context of the long-standing issue of mixing in infinite ergodic theory, we introduce the idea of mixing for observables possessing an infinite-volume average. The idea is borrowed from statistical mechanics and appears to be relevant, at least for extended systems with a direct physical interpretation. We discuss the pros and cons of a few mathematical definitions that can be devised, testing them on a prototypical class of infinite measure-preserving dynamical systems, namely, the random walks.

description: Coherent electronic transport in single-molecule junctions is investigated in the Coulomb blockade regime. Both the transmission phase and probability are calculated for junctions with various contact symmetries. A dramatic suppression of the Coulomb blockade peaks is predicted for junctions where multiple atomic orbitals of the molecule couple to a single electrode although the charging steps are unaffected.

Un team di astronomi ha usato il Very Large Array e il satellite infrarosso Spitzer della Nasa per compiere la prima misura della velocità del vento atmosferico di una nana bruna – un corpo celeste a metà fra un pianeta e una stella. Un metodo semplice e già utilizzato per pianeti come Giove, innovativa però la sua applicazione ad altri corpi celesti, e facilmente estendibile alle atmosfere esoplanetarie. Lo studio è pubblicato su Science

description: We use the statistics of regions above or below a temperature threshold (excursion sets) to study the cosmic microwave background (CMB) anisotropy in models with primordial non-Gaussianity of the local type. By computing the full-sky spatial distribution and clustering of pixels above/below threshold from a large set of simulated maps with different levels of non-Gaussianity, we find that a positive value of the dimensionless non-linearity parameter f_NL enhances the number density of the cold CMB excursion sets along with their clustering strength, and reduces that of the hot ones. We quantify the robustness of this effect, which may be important to discriminate between the simpler Gaussian hypothesis and non-Gaussian scenarios, arising either from non-standard inflation or alternative early-universe models. The clustering of hot and cold pixels exhibits distinct non-Gaussian signatures, particularly at angular scales of about 75 arcmin (i.e. around the Doppler peak), which increase linearly with f_NL. Moreover, the clustering changes strongly as a function of the smoothing angle. We propose several statistical tests to maximize the detection of a local primordial non-Gaussian signal, and provide some theoretical insights within this framework, including an optimal selection of the threshold level. We also describe a procedure which aims at minimizing the cosmic variance effect, the main limit within this statistical framework.

description: We interpret different constructions of the algebraic $K$-theory of spaces as an instance of derived Koszul (or bar) duality and also as an instance of Morita equivalence. We relate the interplay between these two descriptions to the homotopy involution. We define a geometric analog of the Swan theory $G^{\bZ}(\bZ[π])$ in terms of $Σ^{\infty}_{+} ΩX$ and show that it is the algebraic $K$-theory of the $E_{\infty}$ ring spectrum $DX=S^{X_{+}}$.
Il buco nero che ripiega la luce
Creators: Maura Sandri
Publisher: name: Media Inaf
Year: 2020

Uno studio condotto da ricercatori del Caltech presenta la prima evidenza osservativa del fatto che non tutta la luce irradiata dal disco che circonda un buco nero riesce facilmente a scappare dal buco nero stesso. Parte della luce viene ripiegata dal campo gravitazionale e, solo dopo essere stata riflessa dal disco, riesce a fuggire. Lo studio è in uscita su ApJ
gamma Cassiopeiae: an X-ray Be star with personality

description: gamma Cassiopeiae (gCas) is a B0.5e star with peculiar X-ray emission properties and yet the prototype of its own small class. In this paper we examine the X-ray spectra for a 2004 XMM-Newton observation and a previously published 2001 Chandra observation. In both cases the spectra can be modeled with 3 or 4 thermal components, which appear be discrete in temperature and spatially distinct. The dominant component, having kT ~ 12 keV contributes most (~80-90%) of the flux. The secondary components have temperatures in the range of 2-3 keV to 0.1 keV; these values can shift in time. Importantly, we find that the strong absorption of soft X-rays in 2001 is absent in 2004, meaning that an absorbing column in front of the source has moved off the star or has been removed. Other differences include a reduced Fe abundance from the ionized lines of the FeKalpha complex (even more subsolar than the 2001 observation), a decrease of the Fe K and possibly of the Si K fluorescence features, and from the NVII and NeX H-alpha lines, a possible overabundance of N and Ne. Also, we note common characteristics in both spectra that seem to set gCas apart from HD110342, another member of this subclass studied in detail. In this sense these stars have different "personalities." For example, for gCas rapid X-ray flaring and slower changes in the light curve are only seldomly accompanied by variations in hardness, and the hot X-ray component remains nearly constant in temperature. Moreover, the light curve shows recurrent "lulls" in flux, suggesting that a relaxation cycle is operates as part of the (unknown) X-ray generation process.
