description: The physical conditions for the emergence of the extremely low-lying nuclear isomer $^{229m}$Th at approximately 8 eV are investigated in the framework of our recently proposed nuclear structure model. Our theoretical approach explains the $^{229m}$Th-isomer phenomenon as the result of a very fine interplay between collective quadrupole-octupole and single-particle dynamics in the nucleus. We find that the isomeric state can only appear in a rather limited model space of quadrupole-octupole deformations in the single-particle potential, with the octupole deformation being of a crucial importance for its formation. Within this deformation space the model-described quantities exhibit a rather smooth behaviour close to the line of isomer-ground state quasi-degeneracy determined by the crossing of the corresponding single-particle orbitals. Our comprehensive analysis confirms the previous model predictions for reduced transition probabilities and the isomer magnetic moment, while showing a possibility for limited variation in the ground-state magnetic moment theoretical value. These findings prove the reliability of the model and suggest that the same dynamical mechanism could manifest in other actinide nuclei giving a general prescription for the search and exploration of similar isomer phenomena.

description: Forgetfulness is a common feature of nature. Moreover, without forgetfulness, repeatability would be impossible. Despite this, small systems constantly leak information about their state to their surroundings, and quantum mechanics tells us that this information cannot be deleted, invariably returning to influence their future behaviour. How can physical nature be forgetful if it is forbidden to forget? The results within this thesis bridge this gap between what we see in the real world and what idealised physical theories say, explaining the emergence of forgetful processes from closed quantum dynamics and allowing to quantify the rate at which memory effects become relevant.

The quest for Type 2 quasars: Chandra observations of luminous obscured quasars in the Sloan Digital Sky Survey

description: We report on new Chandra exploratory observations of six candidate Type 2 quasars at z=0.49-0.73 selected among the most [OIII] luminous emitters from the Sloan Digital Sky Survey (SDSS). Under the assumption that [OIII] is a proxy for the intrinsic luminosity of the central source, their predicted rest-frame X-ray luminosities are L(2-10keV)~10^45 erg/s. For two of the targets, the photon statistics are good enough to allow for basic X-ray spectral analyses, which indicate the presence of intrinsic absorption (~10^{22-23} cm^-2) and luminous X-ray emission (L_X>10^44 erg/s). Of the remaining four targets, two are detected with only a few (3-6) X-ray counts, and two are undetected by Chandra. If these four sources have the large intrinsic X-ray luminosities predicted by the [OIII] emission, then their nuclei must be heavily obscured (N_H>few 10^23 cm^-2) and some might be Compton thick (N_H>1.5 10^24 cm^-2). We also present the results for two Type 2 quasar candidates serendipitously lying in the fields of the Chandra targets, and provide an up-to-date compilation of the X-ray properties of eight additional SDSS Type 2 quasars from archival Chandra and XMM-Newton observations (five with moderate-quality X-ray data). The combined sample of 16 SDSS Type 2 quasars (10 X-ray detections) provides further evidence that a considerable fraction of optically selected Type 2 quasars are obscured in the X-ray band (at least all the objects with moderate-quality X-ray spectra), lending further support to the findings presented in Vignali, Alexander and Comastri (2004a) and unification schemes of Active Galactic Nuclei, and confirms the reliability of [OIII] emission in predicting the X-ray emission in obscured quasars.

description: We apply Bogolubov approach to QCD with two light quarks to demonstrate a spontaneous generation of an effective interaction, leading to the Nambu -- Jona-Lasinio model. The resulting theory contains two parameters: average low-energy value of $α_s$ and current light quark mass $m_0$. All other low-energy parameters: the pion decay constant, mass of the $π$-meson, mass of the $σ$-meson and its width, the constituent quark mass, the quark condensate are expressed in terms of the two input parameters in satisfactory correspondence to experimental data and chiral phenomenology. {\it E.g.} in the approximation being used we have for $α_s = 0.67$ and $m_0 = 20 MeV$: $f_π= 93 MeV, m_π= 135 MeV, m_σ= 492 MeV, Γ_σ= 574 MeV, m_q = 295 MeV, = -(222 MeV)^3$.

The absence of a cavity makes the system immune to external perturbations, and the strong quantum noise reduction is observed over a large frequency range.

description: We present a combined theoretical and experimental study of X-ray optical wave mixing. This class of nonlinear phenomena combines the strengths of spectroscopic techniques from the optical domain, with the high-resolution capabilities of X-rays. In particular, the spectroscopic sensitivity of these phenomena can be exploited to selectively probe valence dynamics. Specifically, we focus on the effect of X-ray parametric down-conversion. We present a theoretical description of the process, from which we deduce the observable nonlinear response of valence charges. Subsequently, we simulate scattering patterns for realistic conditions and identify characteristic signatures of the nonlinear conversion. For the observation of this signature, we present a dedicated experimental setup and results of a detailed investigation. However, we do not find evidence of the nonlinear effect. This finding stands in strong contradiction to previous claims of proof-of-principle demonstrations. Nevertheless, we are optimistic to employ related X-ray optical wave mixing processes on the basis of the methods presented here for probing valence dynamics in the future.
The effects of salinity on survival, growth, aerobic metabolism and ion regulation in early life stages of Pacific salmonids
Creators: name: Morgan, John D.
Publisher: name: University of British Columbia
Year: 2010

description: A series of laboratory experiments were conducted to test the hypothesis that the energetic requirements for ion regulation in early life stages of three Pacific salmonids would be minimal at an isotonic water salinity (8-10 ppt). Hatching success, alevin survival, time to hatching, size, and metabolic rates were measured for steelhead (Oncorhynchus mykiss) and fall chinook salmon (O. tshawytscha) embryos incubated in four salinities (0, 4, 8 and 12 ppt) from the eyed stage. Egg hatchability was relatively high in all four salinities, but completion of hatch was delayed in the hypertonic (12 ppt) salinity. Newly hatched alevins were also smaller and showed decreased survival in 12 ppt salinity. Salinity effects on alevin survival and size were greater for steelhead trout than for chinook salmon. Metabolic rates of eyed steelhead trout eggs, and chinook salmon eggs and alevins were not significantly affected by the salinities tested. The metabolic rate of newly hatched steelhead trout alevins, however, was significantly elevated in 12 ppt salinity compared to the other treatments. The results indicated that a salinity of 8 ppt is the upper limit for the normal development of steelhead trout and chinook salmon eggs and alevins. The regulation of movements of ions and water in eggs and alevins of these salmonid species may rely on passive processes, such as low membrane permeabilities and tissue tolerances, rather than active mechanisms of ion and osmotic regulation. Rainbow trout, steelhead trout and fall chinook salmon fry were acclimated to a range of salinities, with one near isotonic. Survival, growth, metabolic rate, plasma Na⁺ and Cl⁻ concentrations, and seawater adaptability were measured for 5 to 12 weeks, depending on the species. Growth of all three species was highest in fresh water and declined with increasing salinity. Metabolic rates increased with salinity and were inversely correlated with growth rates. Isotonic salinity, therefore, did not offer significant metabolic or growth advantages to rainbow, steelhead and chinook fry. While plasma Na⁺ and Cl⁻ concentrations varied among groups, chinook fry tended to better maintain ionic homeostasis at higher salinities than the trout. Acclimation to the various dilute salinities did not influence the seawater adaptability of juvenile steelhead trout or chinook salmon. These results indicate that optimal salinities for growth and metabolic rates were influenced by species and life history stage. The metabolic rate data suggested that the energetic cost of ionic regulation increased with salinity, but attempts to quantify this cost were probably affected by other metabolic processes which responded to changes in salinity.

description: In this paper we apply the method of Lagrangian descriptors to explore the geometrical structures in phase space that govern the dynamics of dissipative systems. We demonstrate through many classical examples taken from the nonlinear dynamics literature that this tool can provide valuable information and insights to develop a more general and detailed understanding of the global behavior and underlying geometry of these systems. In order to achieve this goal, we analyze systems that display dynamical features such as hyperbolic points with different expansion and contraction rates, limit cycles, slow manifolds and strange attractors. Furthermore, we study how this technique can be used to detect transition ellipsoids that arise in Hamiltonian systems subject to dissipative forces, and which play a crucial role in characterizing trajectories that evolve across an index-1 saddle point of the underlying potential energy surface.

Q-based design equations for resonant metamaterials and experimental validation

description: Practical design parameters of resonant metamaterials, such as loss tangent, are derived in terms of the quality factor $Q$ of the resonant effective medium permeability or permittivity. Through electromagnetic simulations of loop-based resonant particles, it is also shown that the $Q$ of the effective medium response is essentially equal to the $Q$ of an individual resonant particle. Thus, by measuring the $Q$ of a single fabricated metamaterial particle, the effective permeability or permittivity of a metamaterial can be calculated simply and accurately without requiring complex simulations, fabrication, or measurements. Experimental validation shows that the complex permeability analytically estimated from the measured $Q$ of a single fabricated self-resonant loop agrees with the complex permeability extracted from $S$ parameter measurements of a metamaterial slab to better than 20%. This $Q$ equivalence reduces the design of a metamaterial to meet a given loss constraint to the simpler problem of the design of a resonant particle to meet a specific $Q$ constraint. This analysis also yields simple analytical expressions for estimating the loss tangent of a planar loop magnetic metamaterial due to ohmic losses. It is shown that $\tan δ\approx 0.001$ is a strong lower bound for magnetic loss tangents for frequencies not too far from 1 GHz. The ohmic loss of the metamaterial varies inversely with the electrical size of the metamaterial particle, indicating that there is a loss penalty for reducing the particle size at a fixed frequency.

La nuova vita delle antiche cose: l’opera sullo schermo e il «Don Giovanni» di Peter Sellars

Publisher: name: Pavia University Press - Edizioni dell'Università degli Studi di Pavia
Year: 2009

description: Nel dibattito recente ricorrono sempre più spesso i termini di cine-opera, 			opera sullo schermo o opera in video. A questo proposito, alcuni studiosi hanno messo in luce le relazioni  			intertestuali o intermediali tra opera e cinema (o video), mentre  			altri hanno sottolineato come l’opera in video passi dai territori  			della cultura ‘alta’ a quella bassa e popolare. Solo pochi studiosi  			(Citron, Cook) hanno sostenuto la necessità di considerare la  			cine-opera come un genere indipendente con caratteristiche proprie,  			o come una forma discorsiva che dà luogo a un particolare tipo di  			esperienza estetica.
 			Se si prende in  			esame la messa in scena visionaria e postmoderna del Don Giovanni  			realizzata da Peter Sellars, si può persino dubitare di essere di  			fronte alla celebre opera mozartiana. Sellars conserva la lingua  			italiana e la partitura originale, ma ambienta la vicenda in  			America, nel Bronx, alla fine del XX secolo. Nel far ciò, esaspera  			la violenza e la lotta per la vita originariamente contenute nel  			‘dramma giocoso’ e riarticola il significato originale dell’opera in  			una nuova direzione che egli pensa più adatta ai tempi nostri. Nella  			direzione indicata da Citron, penso sia meglio considerare il lavoro  			di Sellars in termini di stratificazione piuttosto che di fedeltà.  			L’analisi dell’ouverture esplicita il modo in cui Sellars opera sul  			testo.
 			Ma, a livello più  			generale, è possibile affrontare il rapporto tra cinema e opera in  			termini di ri-mediazione, convergenza e ri-locazione? E questi  			paradigmi, spesso usati nella teoria dei media contemporanea, ci  			consentono di capire la transizione dell’opera dal teatro a nuovi  			ambienti tecnologici e culturali?

Comparative experiments on various classification tasks demonstrate the effectiveness of our so-called nearest neighbor weighting (NNeW) scheme. Considering its performance, our procedure can act as a simple and effective baseline method for importance weighting.

Constraints are often considered by projection onto the constraint set, here we include them explicitly into the dynamical system. We show the applicability and efficiency of the methods on examples of relevance in modern physics applications.

Исследования, проведённые в 2011-2012 и 2015 гг. на трех водотоках Вологодской области (реки Вага, Костюга и Земцовка), позволили получить первые детальные сведения о видовом составе жесткокрылых (Insecta: Coleoptera) в питании европейского хариуса. Всего было идентифицировано 16 видов жесткокрылых из 8 семейств (Carabidae, Haliplidae, Dytiscidae, Hydraenidae, Staphylinidae, Elmidae, Chrysomelidae, Curculionidae). Большая часть обнаруженных видов (56,3%) являются представителями водной фауны (с наибольшим разнообразием семейства Elmidae 4 вида). Водный компонент в питании хариуса, представлен лотическими формами, большинство из которых свойственно олиготрофным водотокам, включая истинно реофильные виды родов Brychius и Deronectes. В пищевом спектре хариуса преобладают мелкие виды жуков (2-5 мм) первого класса. В летний период встречены как водные, так и наземно-воздушные представители Coleoptera, весной только наземные виды. В целом, идентификация компонентов питания до видового уровня позволяет глубже понять пищевые предпочтения рыб-эврифагов.

Victory Gin, served “in handless chine mugs” (53), is part of the workers’ staple diet at the Ministry of Truth, and is sold “at ten cents the large nip” from the small bar (actually, “a mere hole in the wall”, 51) in the canteen; served with cloves, it is the “speciality” (79) of that disreputable place which is the Chestnut Tree Café, where Winston Smith once spotted three fallen-out-of-favor members of the Inner Party – Jones, Aaronson and Rutherford – drink it silently after their release from Oceania prison camps (79). As is typical of the fate of spirits in literature, gin also serves as self-medication and can fuel a kind of inner escapism. It is to make the world “look more cheerful” that Winston gulps it down “like a dose of medicine”, and only after the “shock” of swallowing it can he squeeze himself into his alcove and begin his diary (7); gin clears out Winston’s stomach (53), and is the ultima ratio against that prescient “dull ache” in his belly (105; 106) that originates after bumping into “the girl with dark hair” (later: Julia) one evening outside Mr. Charrington’s shop.

On the role of the Knudsen layer in rapid granular flows

description: A combination of molecular-dynamics simulations, theoretical predictions, and previous experiments are used in a two-part study to determine the role of the Knudsen layer in rapid granular flows. First, a robust criterion for the identification of the thickness of the Knudsen layer is established: a rapid deterioration in Navier-Stokes-order prediction of the heat flux is found to occur in the Knudsen layer. For (experimental) systems in which heat flux measurements are not easily obtained, a rule-of-thumb for estimating the Knudsen layer thickness follows, namely that such effects are evident within 2.5 (local) mean free paths of a given boundary. Second, comparisons of simulation and experimental data with Navier-Stokes order theory are used to provide a measure as to when Knudsen layer effects become non-negligible. Specifically, predictions that do not account for the presence of a Knudsen layer appear reliable for Knudsen layers collectively composing up to 20% of the domain, whereas deterioration of such predictions becomes apparent when the domain is fully comprised of the Knudsen layer.

Fame, teatro e memoria. “I Cannibali” di George Tabori

Publisher: name: Università degli  Studi di Milano

Subjects: Tabori; Cannibali

description: Starting from the representation of the hunger motif in Primo Levi’s If This Is a Man (It. 1947, Engl. 1959) and its variation in George Tabori’s “black mass” The Cannibals (Engl. 1968, Germ. 1969), the contribution aims to re-interpret the complex relationship of autobiographical, historical and fictional elements in the celebrated drama of the Jewish romancier and dramatist (1914-2007), who famously had “a mother tongue, Hungarian, a father tongue, English, and an uncle tongue, German”. The metadramatic structure, combined with the focus on emotional, active memory, is thus related to the intertextual medley of the play as a sign for Tabori’s search of a ‘third way’ in representing the Holocaust on the stage, moving away both from documentarian realism and sentimental celebration of the victims.

description: The presence of bound states in a nanoscale electronic system attached to two biased, macroscopic electrodes is shown to give rise to persistent, non-decaying, localized current oscillations which can be much larger than the steady part of the current. The amplitude of these oscillations depends on the entire history of the applied potential. The bound-state contribution to the {\em static} density is history-dependent as well. Moreover, the time-dependent formulation leads to a natural definition of the bound-state occupations out of equilibrium.

description: A general, consistent and complete framework for geometrical formulation of mechanical systems is proposed, based on certain structures on affine bundles (affgebroids) that generalize Lie algebras and Lie algebroids. This scheme covers and unifies various geometrical approaches to mechanics in the Lagrangian and Hamiltonian pictures, including time-dependent lagrangians and hamiltonians. In our approach, lagrangians and hamiltonians are, in general, sections of certain $\R$-principal bundles, and the solutions of analogs of Euler-Lagrange equations are curves in certain affine bundles. The correct geometrical and frame-independent description of Newtonian Mechanics is of this type.

description: We present optical spectroscopy for 18 halo white dwarfs identified using photometry from the Canada-France Imaging Survey and Pan-STARRS1 DR1 3$π$ survey combined with astrometry from Gaia DR2. The sample contains 13 DA, 1 DZ, 2 DC, and two potentially exotic types of white dwarf. We fit both the spectrum and the spectral energy distribution in order to obtain the temperature and surface gravity, which we then convert into a mass, and then an age, using stellar isochrones and the initial-to-final mass relation. We find a large spread in ages that is not consistent with expected formation scenarios for the Galactic halo. We find a mean age of 9.03$^{+2.13}_{-2.03}$ Gyr and a dispersion of 4.21$^{+2.33}_{-1.58}$ Gyr for the inner halo using a maximum likelihood method. This result suggests an extended star formation history within the local halo population.

description: The shift toward participatory, advocacy and social architecture and planning that occurred in the 1960's and 70's in North America was illustrated with the work of the Community Design Centers. These Community Design Centers provided architectural, planning and technical services to low income groups with an emphasis on user participation. The Community Desgin Center provided a model by which the professional, the student and the community could work together as a team on current issues within the community. This study examines the basic notions of the Community Design Centers in order to determine the principles at work in the model. The Urban Design Center of Vancouver, 1970-76 is used as a specific case study.

description: We report new measurements of the parity-violating asymmetry A_PV in elastic scattering of 3 GeV electrons off hydrogen and 4He targets with ~6.0 degrees. The 4He result is A_PV = (+6.40 +/- 0.23 (stat) +/- 0.12 (syst)) x10^-6. The hydrogen result is A_PV = (-1.58 +/- 0.12 (stat) +/- 0.04 (syst)) x10^-6. These results significantly improve constraints on the electric and magnetic strange form factors G_E^s and G_M^s. We extract G_E^s = 0.002 +/- 0.014 +/- 0.007 at = 0.077 GeV^2, and G_E^s + 0.09 G_M^s = 0.007 +/- 0.011 +/- 0.006 at = 0.109 GeV^2, providing new limits on the role of strange quarks in the nucleon charge and magnetization distributions.

“In hunger for bread, not in thirst for revenge”:  Belly, bellum and rebellion in Coriolanus and The Hunger Games trilogy
Creators: name: Soncini, Sara
Publisher: name: Università degli  Studi di Milano
Year: 2015
Subjects: Coriolanus; The Hunger Games; Shakespeare; intertextuality; Young Adult fiction; dystopia

description: A play saturated with images of food, eating and being eaten, Coriolanus provides the most thoroughgoing exploration of the hunger paradigm within the Shakespearean corpus. From the very early moments of the tragedy, Shakespeare’s emphasis on hunger as a literal, material condition is paralleled by a probing investigation of the rhetorical and metaphorical dimension of alimentary imagery and its problematic applicability, and actual application, in the political sphere – most notably, in Menenius Agrippa’s fable of the belly, a rhetorical attempt at naturalizing social inequality which however fails to appease the plebeians’ threatened uprising against the Roman aristocracy.

Shakespeare’s politicization of hunger has played a crucial role in securing and shaping Coriolanus’s afterlife. This essay deals with a very recent take on Coriolanus by investigating the Shakespearean palimpsest within Suzanne Collins’s highly popular The Hunger Games trilogy (2008-2010). While unacknowledged by the author and so far unregistered in critical studies of the novels, Collins’s extensive borrowing from Coriolanus across the three instalments of her science fiction adventure amounts to a consistent and comprehensive reframing of Shakespeare’s hunger paradigm, here remoulded into cautionary dystopia about the social and political order of the global era.

Real and metaphorical hunger: the case of The Divergent Trilogy
Creators: name: Paravano, Cristina
Publisher: name: Università degli  Studi di Milano
Year: 2015
Subjects: Dystopia; young adult fiction; food; hunger

description: The present contribution investigates how the issue of hunger becomes a means of expressing and communicating personal and social identity in Veronica Roth’s best seller trilogy Divergent (2011-13). Roth portrays a dystopian future developing a multifaceted concept of hunger, both real and figurative, and using food as a cultural metaphor. The trilogy is set in a post-apocalyptic Chicago, whose population is divided into five allegorical factions, according to a number of personal and social characteristics. The life of each faction seems to be based on a form of metaphorical hunger: those who pursue selflessness and altruism belong to Abnegation, peace and harmony to Amity, honesty and truth to Candor, danger and adventure to Dauntless, and knowledge and power to Erudite. Those people who are excluded become factionless: they are outcasts who live their life in extreme poverty and experience real physical hunger. On the other hand, I will show how the numerous references to food and eating pervading the novels help to map the characters’ personalities and identities as single individuals and as groups.

description: We introduce a method for learning provably stable deep neural network based dynamic models from observed data. Specifically, we consider discrete-time stochastic dynamic models, as they are of particular interest in practical applications such as estimation and control. However, these aspects exacerbate the challenge of guaranteeing stability. Our method works by embedding a Lyapunov neural network into the dynamic model, thereby inherently satisfying the stability criterion. To this end, we propose two approaches and apply them in both the deterministic and stochastic settings: one exploits convexity of the Lyapunov function, while the other enforces stability through an implicit output layer. We demonstrate the utility of each approach through numerical examples.
