Economia e felicità. Riflessioni sul dovere di trasformare l’economia
Creators: name: Mancini, Roberto
Publisher: name: Scienze del Territorio
Year: 2019

description: The article describes the cultural, political and spiritual trends apt to promote the conditions for public happiness. In a society dominated by economy human existence suffers division, eradication and submission to the claims of global power systems, like the finance driven market. The adaptation of individuals to the induced form of life, in this society, is based on the adoption of a separation system such that each one believes to be isolated. First of all, therefore, it is necessary to develop forms of community sociability. Experiences of open and fair communities liberate people from their forced isolation. In particular, the article shows the turnabouts required for a radical transformation of economy, apt to make it more adequate in relation to the needs and aspirations of human kind.

description: The high-precision data from hadronic tau decays allows one to extract information on QCD condensates. Using the finalized ALEPH data, we obtain a more rigorous determination of the dimension 6 and 8 condensates for the V-A correlator. In particular, we find that the recent data fix a certain linear combination of these QCD condensates to a precision at the level of O(2%). Our approach relies on more general assumptions than alternative approaches based on finite energy sum rules.

Self-Gravity and Dissipation in Polar Rings
Creators: name: Dubinski, John
name: Christodoulou, Dimitris
Publisher: name: arXiv
Year: 1993
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We construct models of highly-inclined (``polar'') rings in an external potential including both self--gravity and dissipation due to a drag force. We adopt the oblate spheroidal scale--free logarithmic potential with axis ratio $q=0.85$ and an initial inclination of 80$^\circ$ for the self--gravitating rings. Stellar (dissipationless) rings suffer from mass loss during their evolution which drives a secular change of the mean inclination toward the poles of the potential. As much as half of the ring mass escapes in the process and forms an inner and an outer shell of precessing orbits. If the remaining mass is more than $\sim$ 0.02 of the enclosed galaxy mass, rings remain bound and and are not destroyed by differential precession. The rings precess at a constant rate for more than a precession period $τ_p$ finding the configuration predicted by Sparke in 1986 which warps at larger radii toward the poles of the potential. We model shear viscosity with a velocity-dependent drag force and find that nuclear inflow dominates over self--gravity if the characteristic viscous inflow time scale $τ_{vi}$ is shorter than $\sim 25 τ_p$. Rings with $τ_{vi}/τ_p \ \sles \ 25$ collapse toward the nucleus of the potential within one precession period independent of the amount of self--gravity. Our results imply that stars and gas in real polar rings exhibit markedly different dynamical evolutions.

Lowered Evans Models: Analytic Distribution Functions of Oblate Halo Potentials

Publisher: name: arXiv
Year: 1993
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We describe an analytic distribution function of a finite, oblate stellar system that is useful for the practical modelling of dark halos. The function is determined by lowering Evans's (1993) distribution function of a flattened, cored isothermal system in analogy to the lowering of the singular, isothermal sphere in the definition of the King (1966) models. We derive analytic expressions of the density, maximal streaming velocity and velocity dispersion profiles as a function of the potential. As for the King models, the potential must be calculated numerically. We also present a recipe for generating N-body realizations of this distribution function and examine the stability in three models with dimensionless spins $λ=$0.0, 0.05 and 0.18 using N-body simulations with 50,000 particles. The $λ=0.18$ model is unstable to the formation of a triaxial bar within $\sim 5$ King radii while the other models appear stable. We conclude that the slowly rotating systems are useful for modelling flattened dark halos.

description: Measurement systems for particle sizing starting at 1 nm are used to bridge the gap between mass spectrometer measurements and traditional aerosol sizing methods, and thus to enable measurement of the complete size distribution from molecules and clusters to large particles. Such a measurement can be made using a scanning mobility particle sizer equipped with a diethylene glycol growth engine (e.g., TSI Model 3777 Nano Enhancer) along with a condensation particle counter, and a differential mobility analyzer (DMA) appropriate for such small sizes. Previous researchers have used high-resolution DMA (HRDMA) and also the TSI Nano-DMA (Model 3085) in such a scanning mobility particle sizer system. In this study, we evaluate the performance of the recently introduced TSI 1 nm-DMA (Model 3086). The transfer function was characterized using 1–2 nm monomobile molecular ion standards. The same measurements were repeated on a TSI Nano-DMA, with good agreement to previously published values. From the measured transfer function, the resolution of each DMA model was determined as a function of particle size and sheath flow rate. Resolution of the TSI 3086 in the 1–2 nm range was 10–25% higher than the TSI 3085. Measured resolutions of the TSI 3086 were 10–20% lower than theoretically predicted values, whereas those of the Model 3085 were 0–10% lower. Copyright © 2018 TSI Inc.
Model-independent predictions for decays of hidden-heavy hadrons into pairs of heavy hadrons

Year: 2024

description: Hidden-heavy hadrons can decay into pairs of heavy hadrons through transitions from confining Born-Oppenheimer potentials to hadron-pair potentials with the same Born-Oppenheimer quantum numbers. The transitions are also constrained by conservation of angular momentum and parity. From these constraints, we derive model-independent selection rules for decays of hidden-heavy hadrons into pairs of heavy hadrons. The coupling potentials are expressed as sums of products of Born-Oppenheimer transition amplitudes and angular-momentum coefficients. If there is a single dominant Born-Oppenheimer transition amplitude, it factors out of the coupling potentials between hidden-heavy hadrons in the same Born-Oppenheimer multiplet and pairs of heavy hadrons in specific heavy-quark-spin-symmetry doublets. If furthermore the kinetic energies of the heavy hadrons are much larger than their spin splittings, we obtain analytic expressions for the relative partial decay rates in terms of Wigner 6-j and 9-j symbols. We consider in detail the decays of quarkonia and quarkonium hybrids into the lightest heavy-meson pairs. For quarkonia, our model-independent selection rules and relative partial decay rates agree with previous results from quark-pair-creation models in simple cases and give stronger results in other cases. For quarkonium hybrids, we find disagreement even in simple cases.

Effects of updating rules on the coevolving prisoner's dilemma
Creators: name: Takesue, Hirofumi
Publisher: name: arXiv
Year: 2017
Subjects: subject: Physics and Society (physics.soc-ph)
subject: FOS: Physical sciences

description: We studied the effect of three strategy updating rules in coevolving prisoner's dilemma games where agents (nodes) can switch both the strategy and social partners. Under two node-based strategy updating rules, strategy updating occurs between a randomly chosen focal node and its randomly selected neighbour. The focal agent becomes the strategy recipient and may imitate the strategy of the neighbour according to the payoff difference, i.e. voter-model-like dynamics (VMLD), or becomes a strategy donor and thus may be imitated by the neighbour, i.e. invasion-process-like dynamics (IPLD). For edge-based updating rules, one edge is selected, and the roles of the two connected nodes (donor or recipient) are randomly decided, i.e. edge-based dynamics (EBD). A computer simulation shows that partner switching supports the evolution of cooperation under VMLD, which has been utilised in many studies on spatial evolutionary games, whereas cooperators often vanish under IPLD. The EBD results lie between these two processes. This difference is prominent among nodes with large degrees. In addition, partner switching induces a non-monotonic relationship between the fraction of cooperators and intensity of selection under VMLD and EBD, and a weak or strong selection supports cooperation. In contrast, only a strong selection supports cooperators under IPLD. Similar differences in the enhancement of cooperation are observed when games are played on static heterogeneous networks. Our results imply that the direction of imitation is quite important for understanding the evolutionary process of cooperation.

description: Recently, some reformulations of the Yang-Mills theory inspired by the Cho-Faddeev-Niemi decomposition have been developed in order to understand confinement from the viewpoint of the dual superconductivity. In this paper we focus on the reformulated $SU(N)$ Yang-Mills theory in the minimal option with $U(N-1)$ stability group. Despite existing numerical simulations on the lattice we perform the perturbative analysis to one-loop level as a first step towards the non-perturbative analytical treatment. First, we give the Feynman rules and calculate all renormalization factors to obtain the standard renormalization group functions to one-loop level in light of the renormalizability of this theory. Then we introduce a mixed gluon ghost composite operator of mass dimension two and show the BRST invariance and the multiplicative renormalizability. Armed with these results, we argue the existence of the mixed gluon-ghost condensate by means of the so-called local composite operator formalism, which leads to various interesting implications for confinement as shown in preceding works.

description: The many experiences of territorial heritage enhancement developed in Italy show how recognising the close link between community and territory can be the basis for paths of sustainable local development. How to translate this practice legacy to render it useful in deeply different contexts, such as the Global South countries, where centuries of colonisation and exploitation of resources as well as of the population (like in Latin America) have permanently altered any balance between the man and the environment? The paper organises some reflections emerged from researches and projects developed by the writer inside the LabPSM – Laboratory City and territory in the countries of the Global South – of the University of Florence, within the broader framework of post-colonial studies. The main issue explored concerns projects and policies for the requalification of informal settlements, with regard to which a contribution is offered in terms of criticism and construction of meanings and methodologies.

description: We consider the habitability of Earth-analogs around stars of different masses, which is regulated by the stellar lifetime, stellar wind-induced atmospheric erosion, and biologically active ultraviolet (UV) irradiance. By estimating the timescales associated with each of these processes, we show that they collectively impose limits on the habitability of Earth-analogs. We conclude that planets orbiting most M-dwarfs are not likely to host life, and that the highest probability of complex biospheres is for planets around K- and G-type stars. Our analysis suggests that the current existence of life near the Sun is slightly unusual, but not significantly anomalous.

description: A vector dark matter candidate, also known as dark photon, would induce an oscillating electric field through kinetic mixing. One detection strategy uses a spherical reflector to focus the induced emission at its center of curvature. On one hand, we investigate the effects of diffraction in this type of experiment from an analytical standpoint, making use of the Kirchhoff integral theorem in the low-curvature dish limit. On the other hand, we estimate the impact of mode-matching, in the case of detection by a pyramidal horn antenna. We show that the expected signal intensity can be significantly reduced compared to usual estimates. Our method is applied to the re-interpretation of the SHUKET experiment data, the results of which are shown to be degraded by a factor of $\sim$~50 due to both diffraction and mode-matching. The analytical method allows optimizing some experimental parameters to gain sensitivity in future runs. Our results can be applied to any dish antenna experiment using a low curvature reflector.

Anomalies of Discrete Symmetries and Gauge Coupling Unification

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The anomaly of a discrete symmetry is defined as the Jacobian of the path-integral measure. Assuming that the anomaly at low energies is cancelled by the Green-Schwarz (GS) mechanism at a fundamental scale, we investigate possible Kac-Moody levels for anomalous discrete family symmetries. As the first example, we consider discrete abelian baryon number and lepton number symmetries in the minimal supersymmetric standard model with the see-saw mechanism, and we find that the ordinary unification of gauge couplings is inconsistent with the GS conditions, indicating the possible existence of further Higgs doublets. We consider various recently proposed supersymmetric models with a non-abelian discrete family symmetry. In a supersymmetric example with $Q_{6}$ family symmetry, the GS conditions are such that the gauge coupling unification appears close to the Planck scale.

Orme di pietra nel paesaggio: un museo per riannodare il rapporto tra una comunità e il suo territorio
Creators: name: Decandia, Lidia
Publisher: name: Scienze del Territorio
Year: 2019

description: The topic of this article is a museum called MATER (MOTHER in Latin), created in the small village of Mamoiada in central Sardinia. As everywhere in the backbone of the Italian peninsula, in this village the disappearance of farming and animal-rearing society has led to a process of detachment between community and territories. The museum was built with the aim to offer, by re-interpreting some of the stony footprints deposited in the landscape, some instruments that might help restoring this relationship. It does so by producing new forms of narration tending to bring to the surface a new, ‘poetic’, though collective at the same time, vision of this particular territorial asset. By combining expert and context knowledge and through an interactive involvement of the community, the museum was conceived as an interactive, relational and convivial work-in-progress in which, thanks to the use of an anachronistic perspective, of art languages and multimedia devices, it is possible to re-connect the different temporalities existing in the territory and to provide instruments pointed at recreating a perception of this as an ‘intelligent environment’, interweaving objects of affection, visions, concepts and symbols left to us by the previous generations and which we must learn again to cherish.

In particular, we critically discuss the question if (and how) a pomeron-like behaviour can be derived from this Euclidean-Minkowskian duality.

description: This paper is the result of a long-lasting research experience dedicated to topics related to urban seismic risk, addressed at promoting a radical shift towards an approach in which seismic risk, a fundamental feature of the best part of Italian territories, is no longer considered as an ‘unexpected’ event and may be included in the structural components every spatial planning choice should take into account. Emergency policies, which have always prevailed in Italy, besides being very controversial as for the decision making processes and the choices they generate, proved and still prove to be largely inefficient. Moreover, the 2016 earthquake in Central Italy is highlighting issues going far beyond the debate on reconstruction models. One concerns the future of several small towns in ‘inland areas’, already exposed to important depopulation and abandonment processes. Which are the possible scenarios? Which the reference models? How are decisions made? In a different view with respect to the dominant one, such territories represent a fundamental asset whose value, often underestimated, lays first of all in the support they offer to the overall territorial structure of the country. We reflect then on such topics taking the case of Accumoli (a small centre strongly hit by the Central Italy earthquake) as an example.

description: Low Earth Orbit Satellite Networks such as Starlink promise to provide world-wide Internet access. While traditionally designed for stationary use, a new dish, released in April 2023 in Europe, provides mobile Internet access including in-motion usage, e.g., while mounted on a car. In this paper, we design and build a mobile measurement setup. Our goal is to fully autonomously conduct continuous Starlink measurements while the car is in motion. We share our practical experiences, including challenges regarding the permanent power supply. We measure the Starlink performance over the span of two months from mid-January to mid-March 2024 when the car is in motion. The measurements consist of all relevant network parameters, such as the download and upload throughput, the RTT, and packet loss, as well as detailed power consumption data. We analyze our dataset to assess Starlink's mobile performance in Central Europe, Germany, and compare it to stationary measurements in proximity. We find that the mobile performance is significantly worse than stationary performance. The power consumption of the new dish is higher, but seems to be more correlated to the heating function of the dish than to the speed of the vehicle.

description: We study nonlinear wave phenomena in self-gravitating fluid systems, with a particular emphasis on applications to molecular clouds. This paper presents analytical results for one spatial dimension. We show that a large class of physical systems can be described by theories with a ``charge density'' $q(ρ)$; this quantity replaces the density on the right hand side of the Poisson equation for the gravitational potential. We use this formulation to prove general results about nonlinear wave motions in self-gravitating systems. We show that in order for stationary waves to exist, the total charge (the integral of the charge density over the wave profile) must vanish. This ``no-charge'' property for solitary waves is related to the capability of a system to be stable to gravitational perturbations for arbitrarily long wavelengths. We find necessary and sufficient conditions on the charge density for the existence of solitary waves and stationary waves. We then apply these results to study nonlinear waves in Jeans-type theories, Yukawa theories, and a pseudo-two-dimensional treatment. We study the allowed types of wave behavior for all of these models. Finally, we discuss the implications of this work for molecular cloud structure.

description: Objective: This US retrospective cohort study compared the real-world effectiveness of canagliflozin 300 mg versus dapagliflozin 10 mg on HbA1c reduction in patients with type 2 diabetes mellitus (T2DM). Methods: Patients initiated on canagliflozin 300 mg or dapagliflozin 10 mg were identified from de-identified claims data in the Optum Clinformatics database (1 January 2014–30 September 2016). Propensity score matching was used to create balanced cohorts. The primary outcome was the proportion of patients with HbA1c <8.0% (HEDIS target); secondary outcomes included the proportion of patients with HbA1c <7.0% (ADA target) and >9.0% (HEDIS poor control), absolute change in HbA1c, and treatment patterns. Results: At 6 months post-index (intent-to-treat population), a significantly higher proportion of patients in the canagliflozin 300 mg versus dapagliflozin 10 mg cohort achieved HbA1c <8.0% (70.8% vs. 59.1%; OR [95% CI]: 1.60 [1.26, 2.04]; p = .0001) and HbA1c <7.0% (36.7% vs. 25.1%; OR [95% CI]: 1.75 [1.34, 2.27]; p 9.0%. Mean HbA1c reduction was −1.17% with canagliflozin 300 mg and −0.91% with dapagliflozin 10 mg (difference of −0.26%; p = .0049). HbA1c results from a sensitivity analysis in the on-treatment population were consistent with the primary analysis. Patients in the canagliflozin 300 mg versus dapagliflozin 10 mg cohort were less likely to discontinue treatment (OR [95% CI]: 0.75 [0.57, 0.99]; p = .0400) or switch medication (OR [95% CI]: 0.72 [0.54, 0.96]; p = .0229). Conclusions: In this real-world study, patients with T2DM initiated on canagliflozin 300 mg had better HbA1c goal attainment and larger HbA1c reduction than patients initiated on dapagliflozin 10 mg.

description: We consider the problem of identifying the topology of a weighted, undirected network $\mathcal G$ from observing snapshots of multiple independent consensus dynamics. Specifically, we observe the opinion profiles of a group of agents for a set of $M$ independent topics and our goal is to recover the precise relationships between the agents, as specified by the unknown network $\mathcal G$. In order to overcome the under-determinacy of the problem at hand, we leverage concepts from spectral graph theory and convex optimization to unveil the underlying network structure. More precisely, we formulate the network inference problem as a convex optimization that seeks to endow the network with certain desired properties -- such as sparsity -- while being consistent with the spectral information extracted from the observed opinions. This is complemented with theoretical results proving consistency as the number $M$ of topics grows large. We further illustrate our method by numerical experiments, which showcase the effectiveness of the technique in recovering synthetic and real-world networks.

description: GravityCam is a new concept of ground-based imaging instrument capable of delivering significantly sharper images from the ground than is normally possible without adaptive optics. Advances in optical and near infrared imaging technologies allow images to be acquired at high speed without significant noise penalty. Aligning these images before they are combined can yield a 2.5 to 3 fold improvement in image resolution. By using arrays of such detectors, survey fields may be as wide as the telescope optics allows. Consequently, GravityCam enables both wide-field high-resolution imaging and high-speed photometry. We describe the instrument and detail its application to provide demographics of planets and satellites down to Lunar mass (or even below) across the Milky Way. GravityCam is also suited to improve the quality of weak shear studies of dark matter distribution in distant clusters of galaxies and multiwavelength follow-ups of background sources that are strongly lensed by galaxy clusters. The photometric data arising from an extensive microlensing survey will also be useful for asteroseismology studies, while GravityCam can be used to monitor fast multiwavelength flaring in accreting compact objects, and promises to generate a unique data set on the population of the Kuiper belt and possibly the Oort cloud.

description: We have performed a series of N-body experiments on Connection Machine-5 in order to simulate the formation of galaxy clusters gravitationally dominated by a massive dark background. In accordance with previous authors we find an extremely inhomogeneous evolution where subcondensations are continually formed and merged. The final distribution of galaxies is more centrally condensed than that of dark matter particles. We have analyzed the origin of this galaxy-dark matter segregation and also the origin of subclustering leading to this effect. We have then analysed, analytically and numerically, the dependence of final segregation on the physical parameters characterizing the model of protocluster. We also find that such a segregation persists even when inelastic encounters of dark halos around galaxies are taken into account. We conclude that this effect cannot be in general avoided in any hierarchical clustering scenario.

description: We study the relative importance of several recent updates of microphysics input to the neutron star cooling theory and the effects brought about by superstrong magnetic fields of magnetars, including the effects of the Landau quantization in their crusts. We use a finite-difference code for simulation of neutron-star thermal evolution on timescales from hours to megayears with an updated microphysics input. The consideration of short timescales ($\lesssim1$ yr) is made possible by a treatment of the heat-blanketing envelope without the quasistationary approximation inherent to its treatment in traditional neutron-star cooling codes. For the strongly magnetized neutron stars, we take into account the effects of Landau quantization on thermodynamic functions and thermal conductivities. We simulate cooling of ordinary neutron stars and magnetars with non-accreted and accreted crusts and compare the results with observations. Suppression of radiative and conductive opacities in strongly quantizing magnetic fields and formation of a condensed radiating surface substantially enhance the photon luminosity at early ages, making the life of magnetars brighter but shorter. These effects together with the effect of strong proton superfluidity, which slows down the cooling of kiloyear-aged neutron stars, can explain thermal luminosities of about a half of magnetars without invoking heating mechanisms. Observed thermal luminosities of other magnetars are still higher than theoretical predictions, which implies heating, but the effects of quantizing magnetic fields and baryon superfluidity help to reduce the discrepancy.

description: L’accesso alla casa in Italia è particolarmente complicato per chi “parte da zero”, come i giovani e gli immigrati, a maggior ragione se presenti da poco nel paese come i richiedenti asilo e titolari di protezione internazionale in uscita dai progetti di prima e seconda accoglienza nel sistema SPRAR o dai CAS. Il sistema abitativo italiano è infatti caratterizzato da un alto tasso di abitazioni in proprietà, una bassa quota di edilizia pubblica, un basso livello di protezione sociale nel mercato in affitto, un importante ruolo della famiglia nella produzione e riproduzione sociale dell’accesso alla casa. Tutte caratteristiche che – unite all’esistenza di discriminazioni nel mercato abitativo - rappresentano un fattore di esclusione per chi non ha una famiglia da cui ereditare l’accesso alla casa o non ha reddito sufficiente, o sufficientemente stabile, per poter accedere a un mutuo o pagare un affitto dando le garanzie richieste. Dopo aver approfondito questo quadro di sfondo, il paper presenta alcune iniziative promosse e gestite da enti pubblici e/o enti del terzo settore per facilitare l’autonomia abitativa di richiedenti asilo e titolari di protezione internazionale in Italia: accoglienza in famiglia, cohousing e altre iniziative di housing sociale. Vengono poi presentate nelle conclusioni alcuni possibili insegnamenti che si possono trarre dall’analisi di queste iniziative.

description: Questo articolo discute le ragioni della fragilità dell'economia del Mezzogiorno prima della grande crisi e l'aggravamento del divario negli anni 2008-14. Si dimostra che l'ulteriore divaricazione tra aree del paese non è un destino ineluttabile. Una strategia di politica industriale semplice e mirata alla minimizzazione delle intermediazioni clientelari ha dato risultati positivi nel triennio 2015-7. Per il futuro tuttavia una significativa convergenza si potrà concretizzare solo a fronte di una ripresa di investimenti pubblici e privati in capitale fisico ed umano per i quali si esaminano alcune ipotesi concrete.

description: Using a soft-wall AdS/QCD approach we derive the Schrödinger-type equation of motion for the tetraquark wave function, which is dual to the dimension-4 AdS bulk profile. The latter coincides with the number of constituents in the leading Fock state of the tetraquark. The obtained equation of motion is solved analytically, providing predictions for both the tetraquark wave function and its mass. A low mass limit for possible tetraquark states is given by $M \ge 2 κ= 1$ GeV, where $κ= 0.5$ GeV is the typical value of the scale parameter in soft-wall AdS/QCD. We confirm results of the COMPASS Collaboration recently reported on the discovery of the $a_1(1414)$ state, interpreted as a tetraquark state composed of light quarks and having $J^{PC} = 1^{++}$. Our prediction for the mass of this state, $M_{a_1} = \sqrt{2}$ GeV $\simeq 1.414$ GeV, is in good agreement with the COMPASS result $M_{a_1} = 1.414^{+0.015}_{-0.013}$ GeV. Next we included finite quark mass effects, which are essential for the tetraquark states involving heavy quarks.

description: Reverse order law for the Moore-Penrose inverses of tensors are useful in the field of multilinear algebra. In this paper, we first prove some more identities involving the Moore-Penrose inverse of tensors. We then obtain a few necessary and sufficient conditions for the reverse order law for the Moore-Penrose inverse of tensors via the Einstein product.
