description: Hydrodynamics provides a universal description of interacting quantum field theories at sufficiently long times and wavelengths, but breaks down at scales dependent on microscopic details of the theory. In the vicinity of a quantum critical point, it is expected that some aspects of the dynamics are universal and dictated by properties of the critical point. We use gauge-gravity duality to investigate the breakdown of diffusive hydrodynamics in two low temperature states dual to black holes with AdS$_2$ horizons, which exhibit quantum critical dynamics with an emergent scaling symmetry in time. We find that the breakdown is characterized by a collision between the diffusive pole of the retarded Green's function with a pole associated to the AdS$_2$ region of the geometry, such that the local equilibration time is set by infra-red properties of the theory. The absolute values of the frequency and wavevector at the collision ($ω_{eq}$ and $k_{eq}$) provide a natural characterization of all the low temperature diffusivities $D$ of the states via $D=ω_{eq}/k_{eq}^2$ where $ω_{eq}=2πΔT$ is set by the temperature $T$ and the scaling dimension $Δ$ of an operator of the infra-red quantum critical theory. We confirm that these relations are also satisfied in an SYK chain model in the limit of strong interactions. Our work paves the way towards a deeper understanding of transport in quantum critical phases.

The Symposium was sponsored by: the International Agricultural Trade Research Consortium, the Venture Trust, Massey University, New Zealand, and the Centre for Applied Economics and Policy Studies, Massey University. Dietary changes, especially in developing countries, are driving a massive increase in demand for livestock products. The objective of this symposium was to examine the consequences of this phenomenon, which some have even called a "revolution." How are dietary patterns changing, and can increased demands for livestock products be satisfied from domestic resources? If so, at what cost? What will be the flow-on impacts, for example, in terms of increased demands for feedgrains and the pressures for change within marketing systems? A supply-side response has been the continued development of large-scale, urban-based industrial livestock production systems that in many cases give rise to environmental concerns. If additional imports seem required, where will they originate and what about food security in the importing regions? How might market access conditions be re-negotiated to make increased imports achievable? Other important issues discussed involved food safety, animal health and welfare and the adoption of biotechnology, and their interactions with the negotiation of reforms to domestic and trade policies.

description: The substitution of cobalt and nickel for manganese in the perovskite manganate LaBiMn2O6+d; has been realized, leading to the perovskites LaBiMn2-x(M)xO6+d, with M = Co, Ni and x =0-2/3. In contrast to the literature those phases are found to be orthorhombic with Pnma symmetry. More importantly, it is shown that ferromagnetism is enhanced, TC being increased from 80 K for the parent compound (x = 0) to 97 K for Ni-phase, and to 130 K for the Co-phase. Moreover, a strong competition between ferromagnetism and a glassy-ferromagnetic state in the case of nickel or a spin-glass behaviour in the case of cobalt is observed. These phenomena are interpreted in the frame of a phase separation scenario, where the ferromagnetic Mn4+/Ni2+ and Mn4+/Co2+ interactions reinforce the Mn3+/Mn4+ interactions. These compounds are found to be insulating with a relatively large positive value of thermoelectric power.

description: We describe degenerate square spin as an ensemble of magnetic monopoles coupled via an emergent entropic field that subsumes the effect of the underlying spin vacuum. We compute their effective free energy, entropic interaction, correlations, screening, and structure factors that coincide with the experimental ones. Unlike in pyrochlore ices, a dimensional mismatch between real and entropic interactions leads to weak singularities at the pinch points and algebraic correlations at long distance. This algebraic screening can be, however, camouflaged by a pseudo-screening regime.

description: The coherence properties of the classical waves are discussed in terms of the Cauchy problem for the wave equation, and of a discrete representation by an ensemble of Hamiltonian systems. Wave quanta are related to specific "action fields", and phase-space distributions of phonons and photons are obtained by Wigner transform. For photons in a thermal environment, the proposed Wigner function evolves towards the Planck equilibrium distribution. It is shown that the free electromagnetic field can also be found in states of definite helicity, described by a complex vector potential.

description: We argue that the topological string partition function, which has been known to correspond to a wave-function, can be interpreted as an exact ``wave-function of the universe'' in the mini-superspace sector of physical superstring theory. This realizes the idea of Hartle and Hawking in the context of string theory, including all loop quantum corrections. The mini-superspace approximation is justified as an exact description of BPS quantities. Moreover this proposal leads to a conceptual explanation of the recent observation that the black hole entropy is the square of the topological string wave-function. This wave-function can be interpreted in the context of flux compactification of all spatial dimensions as providing a physical probability distribution on the moduli space of string compactification. Euclidean time is realized holographically in this setup.

description: The 1996 farm bill challenges agricultural producers to pursue conservation objectives while allowing flexibility and reducing subsidies. The nature of this challenge for semi-arid rainfed, wind-erosion-prone agriculture is explored via a behavioral model. Simulations of farm-firm decision making under scenarios in the southern Texas High Plains are evaluated. Results indicate that the removal of subsidies, while lowering farm incomes, does not, under most assumptions, alter cropping system choice. Alternatively, under a variety of assumptions, the imposition of an erosion tax shuts down cropping.

description: Quantum antiferromagnets are of broad interest in condensed matter physics as they provide a platform for studying exotic many-body states including spin liquids and high-temperature superconductors. Here, we report on the creation of a one-dimensional Heisenberg antiferromagnet with ultracold bosons. In a two-component Bose-Hubbard system, we switch the sign of the spin-exchange interaction and realize the isotropic antiferromagnetic Heisenberg model in an extended 70-site chain. Starting from a low-entropy Néel-ordered state, we use optimized adiabatic passage to approach the bosonic antiferromagnet. We demonstrate the establishment of antiferromagnetism by probing the evolution of the staggered magnetization and spin correlations of the system. Compared with condensed matter systems, ultracold gases in optical lattices can be microscopically engineered and measured, offering significant advantages for exploring bosonic magnetism and spin dynamics.

description: Attributes for two value-added seafood products derived from underutilized crawfish are analyzed using conjoint data from seafood restaurants in the southern region of the United States. Preferences for the products' form, price, and flavor attributes were tested. Statistical tests revealed that the attribute interactions were not significant, and part-worth utilities for all main effects were estimated using an additive preference model. Results indicate that the new crawfish products should be marketed as a high-quality fresh soup base or seafood stuffing, priced between 30% and 50% of the cost of fresh crawfish tail meat.

description: We analyze the lattice spacing dependence for the pion unpolarized matrix element of a quark bilinear operator with Wilson link (quasi-PDF operator) in the rest frame, using 13 lattice spacings ranging from 0.032 fm to 0.121 fm. We compare results for three different fermion actions with or without good chiral symmetry on dynamical gauge ensembles from three collaborations. This investigation is motivated by the fact that the gauge link generates an $1/a$ divergence, the cancelation of which in many ratios can be numerically tricky. Indeed, our results show that this cancelation deteriorates with decreasing lattice spacing, and that the RI/MOM method leaves a linearly divergent residue for quasi-PDFs. We also show that in the Landau gauge the interaction between the Wilson link and the external state results in a linear divergence which depends on the discretized fermion action.

description: Overcoming the detrimental effect of disorder at the nanoscale is very hard since disorder induces localization and an exponential suppression of transport efficiency. Here we unveil novel and robust quantum transport regimes achievable in nanosystems by exploiting long-range hopping. We demonstrate that in a 1D disordered nanostructure in the presence of long-range hopping, transport efficiency, after decreasing exponentially with disorder at first, is then enhanced by disorder [disorder-enhanced transport (DET) regime] until, counterintuitively, it reaches a disorder-independent transport (DIT) regime, persisting over several orders of disorder magnitude in realistic systems. To enlighten the relevance of our results, we demonstrate that an ensemble of emitters in a cavity can be described by an effective long-range Hamiltonian. The specific case of a disordered molecular wire placed in an optical cavity is discussed, showing that the DIT and DET regimes can be reached with state-of-the-art experimental setups.

description: Understanding the atmospheric low-frequency variability is of crucial importance in fields such as climate studies, climate change detection, and extended-range weather forecast. The Northern Hemisphere climate features the planetary waves as a relevant ingredient of the atmospheric variability. Several observations and theoretical arguments seem to support the idea that winter planetary waves indicator obey a non-Gaussian statistics and may present a multimodal probability density function, thus characterizing the low-frequency portion of the climate system. We show that the upper tropospheric jet strength is a critical parameter in determining whether the planetary waves indicator exhibits a uni- or bimodal behavior, and we determine the relevant threshold value of the jet. These results are obtained by considering the data of the NCEP-NCAR and ECMWF reanalyses for the overlapping period. Our results agree with the non-linear orographic theory, which explains the statistical non-normality of the low-frequency variability of the atmosphere and its possible bimodality.

description: An analytically solvable model for quasi-static transformations across quantum critical points featuring Bosonic quasi-particle excitations is presented. The model proves that adiabaticity breakdown is a general feature of universal slow dynamics in these systems. The existence of an "anti-adiabatic" dynamical phase with vanishing ground state fidelity in the slow drive limit is also proven. The relation of these findings with the Kibble-Zurek mechanism and their consequences on defect formation in many body systems ramped across a quantum phase transition are discussed.

description: This study examines the Law of One Price (LOP) in international commodity markets using fractional cointegration analysis. For proper evaluation of the LOP, fractional cointegration analysis seems to be appropriate because of its flexibility in capturing a wider range of mean reversion behavior than standard cointegration analysis. Out of nine pairs of price series examined, fractional cointegration supports the existence of the LOP in eight cases, as compared to three cases using standard cointegration procedures. Overall, these results suggest that there is a long-run tendency for the LOP to hold for commodity prices.

description: Proton pump inhibitors (PPIs) rank among the most frequently prescribed medications to treat acid-related diseases. Mounting concerns surround the potential for serious adverse events, including cardiovascular events, associated with their prolonged use/misuse. This comprehensive review explores cardiovascular adverse events linked to PPI use among high-risk cardiovascular patients. A structured search was conducted on PubMed Many patients with cardiovascular disease who require antiplatelet treatment will require long-term PPI treatment. Interpreting the published data is not straightforward. First, because there is no plausible mechanistic explanation for PPIs to induce cardiovascular events apart from the potential interaction with the metabolism of thienopyridines. Although several observational studies have shown an increased cardiovascular risk and mortality in patients taking long-term PPIs, most available clinical trials and meta-analyses of available studies do not. However, the absence of firm evidence of this link does not necessarily imply that this association does not exist, and other hypothesis must be explored. Anemia is a common event in patients who take antiplatelet therapy and PPIs, and it is a factor associated with cardiovascular events and death. Anemia in these patients is often attributed to erosive lesions of the small intestine, where PPI may play a key role by modifying the microbiota.

description: En Historia de la Sexualidad, Michael Foucault revela que el discurso decimonónico sobre la sexualidad europeo se convierte en una herramienta más del poder. Este discurso se expandió también a Japón durante la rápida industrialización Meiji y podemos detectar su presencia en lugares como la literatura. A través del análisis de Confesiones de una máscara de Mishima Yukio, veremos cómo dicho discurso sirve para construir el personaje principal de la obra –el narrador– y sus líneas argumentales.Utilizando el análisis de cómo se articula el discurso sobre la sexualidad llevado a cabo por Foucault, podremos detectar qué partes del mismo aparecen en la obra de Mishima y de qué manera. A través de este método, podremos confirmar el trasvase de dicho discurso de poder desde occidente a Japón, y su aparición en esta obra literaria, condicionando la construcción del personaje principal de la misma. Además, podremos determinar qué implicaciones tiene este último hecho, y cómo se relacionan con la visión que el mundo tiene sobre Mishima Yukio.

description: We demonstrate an optical-fiber based source of polarization entangled photon-pairs with improved quality and efficiency, which has been integrated with off-the-shelf telecom components and is, therefore, well suited for quantum communication applications in the 1550 nm telecom band. Polarization entanglement is produced by simultaneously pumping a loop of standard dispersion-shifted fiber with two orthogonally-polarized pump pulses, one propagating in the clockwise and the other in the counter-clockwise direction. We characterize this source by investigating two-photon interference between the generated signal-idler photon-pairs under various conditions. The experimental parameters are carefully optimized to maximize the generated photon-pair correlation and to minimize contamination of the entangled photon-pairs from extraneously scattered background photons that are produced by the pump pulses for two reasons: i) spontaneous Raman scattering causes uncorrelated photons to be emitted in the signal/idler bands and ii) broadening of the pump-pulse spectrum due to self-phase modulation causes pump photons to leak into the signal/idler bands. We obtain two-photon interference with visibility $>90$% without subtracting counts caused by the background photons (only dark counts of the detectors are subtracted), when the mean photon number in the signal (idler) channel is about 0.02/pulse, while no interference is observed in direct detection of either the signal or the idler photons.

description: Finance was born from money, intended as a “bargaining chip”; with finance grew all those instruments to finance trade and production of goods and services, by changing the economic and social structure. But the merchant-bankers accused of usury by Church sought to overcome this sinfulness with donations to charities and by commissioning artworks, which gave luster to the donor family.  But the beauty produced during the Renaissance was not only daughter of money but also daughter and mother of a thought expression of a totally new culture that changed world view emphasizing the human being at the Centre and making it the measure of all things. A culture that has given us in every area, works that still leave us astounded and make us move by defining the infinite spaces of freedom.

Fu dal denaro inteso come “merce di scambio” che nacque la finanza e con essa si svilupparono tutti quegli strumenti atti a finanziare commerci e produzione di beni e servizi  modificando la struttura economica e sociale. Ma i mercanti-banchieri tacciati d’usura  dalla Chiesa cercarono di superare tale condizione di peccato  con elargizioni ad opere di carità e commissionando opere d’arte che davano lustro anche alla Famiglia del donatore.  Ma la bellezza prodotta nel Rinascimento non fu certo figlia solo del denaro  ma anche figlia e madre di un pensiero espressione di una cultura totalmente rinnovata che cambiò la visione del mondo ponendone l’uomo al centro e rendendolo misura di tutte le cose. Una cultura che ci ha regalato in ogni ambito, opere che ancor oggi ci lasciano pieni  di stupore  e ci fanno commuovere  definendo infiniti spazi di libertà.

description: Sound propagation is a macroscopic manifestation of the interplay between the equilibrium thermodynamics and the dynamical transport properties of fluids. Here, for a two-dimensional system of ultracold fermions, we calculate the first and second sound velocities across the whole BCS-BEC crossover and we analyze the system response to an external perturbation. In the low-temperature regime we reproduce the recent measurements [Phys Rev. Lett. {\bf 124}, 240403 (2020)] of the first sound velocity, which, due to the decoupling of density and entropy fluctuations, is the sole mode excited by a density probe. Conversely, a heat perturbation excites only the second sound, which, being sensitive to the superfluid depletion, vanishes in the deep BCS regime, and jumps discontinuously to zero at the Berezinskii-Kosterlitz-Thouless superfluid transition. A mixing between the modes occurs only in the finite-temperature BEC regime, where our theory converges to the purely bosonic results.

description: We describe the effect of the marginal deformation of the $\cal N = (4, 4)$ superconformal $(T^4)^N /S_N$ orbifold theory on a doublet of R-neutral twisted Ramond fields, in the large-$N$ approximation. Our analysis of their dynamics explores the explicit analytic form of the genus-zero four-point function involving two R-neutral Ramond fields and two deformation operators. We compute this correlation function with two different approaches: the Lunin-Mathur path-integral technique and the stress-tensor method. From its short distance limits, we extract the OPE structure constants and the scaling dimensions of non-BPS fields appearing in the fusion. In the deformed CFT, at second order in the deformation parameter, the two-point function of the $n$-twisted Ramond fields is UV-divergent. We perform an appropriate regularization, together with a renormalization of the undeformed fields, obtaining finite, well-defined corrections to their two-point functions and their bare conformal weights, for $n < N$. The fields with maximal twist $n=N$ remain protected from renormalization, with vanishing anomalous dimensions.

description: Lo sviluppo delle fonti rinnovabili a sostegno dell’economia verde, in concomitanza con la pubblicazione della raccomandazione Consob del luglio 2013, ha spronato la stesura di nuove analisi di carattere economico-aziendale, con il fine di giungere ad un progresso incrementale anche dal punto di vista della trasparenza contabile.

In questo contesto di innovazione si inseriscono, immancabili, i dubbi e le preoccupazioni non solo delle associazioni di tutela del territorio, intenzionate a far si che la nuova rivoluzione verde non apporti modifiche che “verdi” non sono, ma anche le difficoltà interpretative dei diretti portatori di interesse.

Ciò in quanto, nella letteratura contabile, si trova ancora poco riguardo alla rappresentazione di informazioni su costi e passività ambientali; in genere, si tratta, infatti, di poste non rappresentate separatamente nei documenti finanziari d’impresa.

Il presente lavoro, partendo dal punto 6 della raccomandazione sopracitata, prende in considerazione i costi di smantellamento e ripristino presenti nel bilancio di uno dei principali parchi eolici italiani, con l’intento di formulare riflessioni riguardo la procedura di rilevazione degli stessi, sia mediante la normativa italiana, sia secondo i principi contabili internazionali IAS/IFRS.

L’elaborato si concentra altresì sul quadro sistematico alla base dei principi contabili che, mediante un approccio prescrittivo, ordina la natura, la funzione ed i limiti dell’informazione economico-finanziaria al fine di valutare se il modello contabile previsto per i costi di smantellamento permetta alle realtà internazionali operanti nel settore delle energie rinnovabili di confrontarsi tra loro e fornire un'informazione equa a tutti i soggetti interessati a prendere parte all'attività d'impresa.

description: Magnetic susceptibility, heat capacity, and electrical resistivity measurements have been carried out on single crystals of the intermediate valence compounds Yb2Rh3Ga9 and Yb2Ir3Ga9. These measurements reveal a large anisotropy due apparently to an interplay between crystalline electric field (CEF) and Kondo effects. The temperature dependence of magnetic susceptibility can be modelled using the Anderson impurity model including CEF within an approach based on the Non-Crossing Approximation.

description: Finite mixture estimation (FME) is compared to estimated generalized least squares (EGLS) in the estimation of economies of size and production cost frontiers for Alabama dairy farms. FME provides several unique insights into the economic forces behind recent changes in Alabama's dairy industry. FME provides estimation of a stochastic average cost frontier with known statistical properties, which it was not otherwise possible to obtain using available stochastic frontier estimation packages.

description: A partire dai primi anni ottanta, le principali democrazie occidentali sono stati teatro di profondi ed innovativi processi di riforma del settore pubblico. Nell’ambito di tale processo riformista, un ruolo fondamentale è stato assunto dalle modifiche che hanno interessato i sistemi di misurazione e rilevazione contabile e che sono state caratterizzate dal graduale passaggio da un sistema contabile basato sul principio di cassa (cash accounting) ad uno, tipico del settore profit, basato sul principio della competenza economica (accrual accounting). In tale contesto, un ruolo fondamentale è stato assunto nel tempo dall’IPSASB, lo standard setter internazionale per il settore pubblico che, sorto nel 1986, ad oggi ha emanato ben 32 principi full accrual basis ed uno solo cash basis. Il presente contributo sorge quindi con lo specifico obiettivo di analizzare alcune delle più significative implicazioni concettuali ed operative associate all’utilizzo di un sistema di contabilità economico-patrimoniale all’interno del settore pubblico, quale ad esempio quello italiano, ancora fortemente cash basis, attraverso la disamina accurata di tre specifici full accrual standard che si ritiene possano più di altri consentire di evidenziarne con immediatezza la portata innovativa, vale a dire: l’IPSAS12 (paragrafo 2), l’IPSAS 13 (paragrafo 3) e l’IPSAS 23 (paragrafo 4), per poi terminare con le considerazioni conclusive dell’autore (paragrafo 5).

description: Galaxy clusters are excellent probes to study the effect of environment on galaxy formation and evolution. Along with high-quality observational data, accurate cosmological simulations are required to improve our understanding of galaxy evolution in these systems. In this work, we compare state-of-the-art observational data of massive galaxy clusters ($>10^{14} \textrm{M}_{\odot}$) at different redshifts ($010^{14} \textrm{M}_{\odot}$ at $z=0$). We compare three fundamental observables of galaxy clusters: the total stellar mass to halo mass ratio, the stellar mass function (SMF), and the radial mass density profile of the cluster galaxies. In the first two of these, the simulations agree well with the observations, albeit with a slightly too high abundance of $M_\star \lesssim 10^{10} \textrm{M}_{\odot}$ galaxies at $z \gtrsim 1$. The NFW concentrations of cluster galaxies increase with redshift, in contrast to the decreasing dark matter halo concentrations. This previously observed behaviour is therefore due to a qualitatively different assembly of the smooth DM halo compared to the satellite population. Quantitatively, we however find a discrepancy in that the simulations predict higher stellar concentrations than observed at lower redshifts ($z<0.3$), by a factor of $\approx$2. This may be due to selection bias in the simulations, or stem from shortcomings in the build-up and stripping of their inner satellite halo.
