description: Recent analysis of data sets from two extensive air shower cosmic ray detectors shows tantalizing evidence of an anisotropic overabundance of cosmic rays towards the Galactic Center (GC) that ``turns on'' around $10^{18}$ eV. We demonstrate that the anisotropy could be due to neutrons created at the Galactic Center through charge-exchange in proton-proton collisions, where the incident, high energy protons obey an $\sim E^{-2}$ power law associated with acceleration at a strong shock. We show that the normalization supplied by the gamma-ray signal from EGRET GC source 3EG J1746-2851 -- ascribed to pp induced neutral pion decay at GeV energies -- together with a very reasonable spectral index of 2.2, predicts a neutron flux at $\sim 10^{18}$ eV fully consistent with the extremely high energy cosmic ray data. Likewise, the normalization supplied by the very recent GC data from the HESS air-Cerenkov telescope at TeV energies is almost equally-well compatible with the $\sim 10^{18}$ eV cosmic ray data. Interestingly, however, the EGRET and HESS data appear to be themselves incompatible. We consider the implications of this discrepancy. We discuss why the Galactic Center environment can allow diffusive shock acceleration at strong shocks up to energies approaching the ankle in the cosmic ray spectrum. Finally, we argue that the shock acceleration may be occuring in the shell of Sagittarius A East, an unusual supernova remnant located very close to the Galactic Center. If this connection between the anisotropy and Sagittarius A East could be firmly established it would be the first direct evidence for a particular Galactic source of cosmic rays up to energies near the ankle.

description: Everyday photographs as well as art photographs may be aesthetically appreciated. Although this may be most obvious in the case of advertising it is also true for amateur photographs. Non-art photographs play an important role in our everyday lives and should not be neglected by aesthetics. That these photographs draw much of their value (often a very personal value) from being associated with memories and musings does not make them non-aesthetic. I discuss these issues drawing on Clive Bell, Lyotard and Bourdieu with special emphasis placed such contemporary art photographers as Nan Goldin and Ed Burtynsky.

Everyday Aesthetic Practices, Ethics and Tact

Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2014

description: The essay addresses the issue of the relationships between everyday aesthetics and ethics from the point of view of tact. Tact is understood as an attitude towards behavior that guides action and thinking, and combines aesthetics with ethics. Tact and tactlessness may manifest themselves in action and speech but also in objects produced and used. I will argue that although tact is often pursued, tactful behavior will necessarily result in conflicting situations in which one is only in step with certain things and in conflict with many others. However, the principle of tact tries to hide its conflictual aspects, unlike, for example, confrontation-based political thinking. Still, within the framework of tact, the contrast between pursuing harmonious behavior and yet necessarily creating conflicts cannot be avoided, which emphasizes the special tragic nature of tact. This kind of tragedy also often characterizes everyday aesthetics. I will approach the theme both through theoretical concepts and concrete examples.

description: We theoretically propose chiral magnon in ferromagnetic chiral crystals. We show that the crystal chirality is imprinted in orbital angular momentum of magnons which exhibits the opposite signs for opposite chiralities of the crystal. We also show that a finite magnon orbital angular momentum can be induced by a temperature gradient which is a magnonic analogue of the Edelstein effect.

description: We report on the electrical detection of a hybrid magnon-photon system, which is comprised of a magnetic sample coupled to a planar cavity. While the uniform Kittel mode has the largest coupling strength among all the magnon modes, it only generates a modest voltage signal by means of inverse spin-Hall effect. We have found that the generated voltage can be significantly enhanced by introducing a higher order magnon mode, which possesses a much higher spin pumping efficiency and furthermore, it is nearly degenerated with the Kittel mode. The experimental results can be explained by our theoretical model, and suggest that the use of an auxiliary magnon mode can realize the configuration of a magnon-photon system with both strong coupling and large spin current.
Hierarchy problem and dimension-six effective operators

description: Without any mechanism to protect its mass, the self-energy of the Higgs boson diverges quadratically, leading to the hierarchy or fine-tuning problem. One bottom-up solution is to postulate some yet-to-be-discovered symmetry which forces the sum of the quadratic divergences to be zero, or almost negligible; this is known as the Veltman condition. Even if one assumes the existence of some new physics at a high scale, the fine-tuning problem is not eradicated, although it is softer than what it would have been with a Planck scale momentum cut-off. We study such divergences in an effective theory framework, and construct the Veltman condition with dimension-six operators. We show that there are two classes of diagrams, the one-loop and the two-loop ones, that contribute to quadratic divergences, but the contribution of the latter is suppressed by a loop factor of $1/16π^2$. There are only six dimension-six operators that contribute to the one-loop category, and the Wilson coefficients of these operators play an important role towards softening the fine-tuning problem. We find the parameter space for the Wilson coefficients that satisfies the extended Veltman condition, and also discuss why one need not bother about the $d>6$ operators. The parameter space is consistent with the theoretical and experimental bounds of the Wilson coefficients, and should act as a guide to the model builders.

description: The growth of social networks makes toxic content spread rapidly. Hate speech detection is a task to help decrease the number of harmful comments. With the diversity in the hate speech created by users, it is necessary to interpret the hate speech besides detecting it. Hence, we propose a methodology to construct a system for targeted hate speech detection from online streaming texts from social media. We first introduce the ViTHSD - a targeted hate speech detection dataset for Vietnamese Social Media Texts. The dataset contains 10K comments, each comment is labeled to specific targets with three levels: clean, offensive, and hate. There are 5 targets in the dataset, and each target is labeled with the corresponding level manually by humans with strict annotation guidelines. The inter-annotator agreement obtained from the dataset is 0.45 by Cohen's Kappa index, which is indicated as a moderate level. Then, we construct a baseline for this task by combining the Bi-GRU-LSTM-CNN with the pre-trained language model to leverage the power of text representation of BERTology. Finally, we suggest a methodology to integrate the baseline model for targeted hate speech detection into the online streaming system for practical application in preventing hateful and offensive content on social media.

description: This paper provides a critical assessment of two diverse methodological approaches in the contemporary movement of Everyday Aesthetics. The “weak formulation” asserts that ordinary objects are best understood on the model of fine art. I counter this claim with a distinction between aesthetic and artistic value. The “strong formulation” develops an ethical-existential theory of the everyday as one of belonging and familiarity which nevertheless causes us to lose what is uniquely aesthetic about our ordinary lives. I strive to find a middle ground that contextualizes the aesthetic within human activities, concerns and judgements.

description: Understanding the determinants of liquidity costs in agricultural futures markets is hampered by a need to use proxies for the bid-ask spread which are often biased, and by a failure to account for a jointly determined micro-market structure. We estimate liquidity costs and its determinants for the live cattle and hog futures markets using alternative liquidity cost estimators, intraday prices and micro-market information. Volume and volatility are simultaneously determined and significantly related to the bid-ask spread. Daily volume is negatively related to the spread while volatility and volume per transaction display positive relationships. Electronic trading has a significant competitive effect on liquidity costs, particularly in the live cattle market. Results are sensitive to the bid-ask spread measure, with a modified Bayesian method providing estimates most consistent with expectations and the competitive structure found in these markets.
Formation and dynamical evolution of galaxies and of their components
Creators: name: Athanassoula, E.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: From this vast subject, I will pick out and review three specific topics, namely the formation and evolution of bars, the formation of bulges, and the evolution during multiple major mergers. Bars form naturally in galactic discs. Their evolution is driven by the exchange of angular momentum within the galaxy. This is emitted mainly by near-resonant material in the inner disc (bar), and is absorbed by near-resonant material in the outer disc and in the halo. As a result of this, the bar becomes stronger and rotates slower. Bulges are not a homogeneous class of objects. Based on their formation history, one can distinguish three types. Classical bulges are mainly formed before the actual disc component, from collapses or mergers and the corresponding dissipative processes. Boxy/peanut bulges are parts of bars seen edge-on. Finally, disc-like bulges are formed by the inflow of material to the center due to bar torques. Major mergers bring strong and fast evolution and can turn discs into ellipticals. I present results from simulations of multiple mergers in groups of disc or of elliptical galaxies and discuss the orbital anisotropy in the merger remnant.

description: Advances in Artificial Intelligence and Image Processing are changing the way people interacts with digital images and video. Widespread mobile apps like FACEAPP make use of the most advanced Generative Adversarial Networks (GAN) to produce extreme transformations on human face photos such gender swap, aging, etc. The results are utterly realistic and extremely easy to be exploited even for non-experienced users. This kind of media object took the name of Deepfake and raised a new challenge in the multimedia forensics field: the Deepfake detection challenge. Indeed, discriminating a Deepfake from a real image could be a difficult task even for human eyes but recent works are trying to apply the same technology used for generating images for discriminating them with preliminary good results but with many limitations: employed Convolutional Neural Networks are not so robust, demonstrate to be specific to the context and tend to extract semantics from images. In this paper, a new approach aimed to extract a Deepfake fingerprint from images is proposed. The method is based on the Expectation-Maximization algorithm trained to detect and extract a fingerprint that represents the Convolutional Traces (CT) left by GANs during image generation. The CT demonstrates to have high discriminative power achieving better results than state-of-the-art in the Deepfake detection task also proving to be robust to different attacks. Achieving an overall classification accuracy of over 98%, considering Deepfakes from 10 different GAN architectures not only involved in images of faces, the CT demonstrates to be reliable and without any dependence on image semantic. Finally, tests carried out on Deepfakes generated by FACEAPP achieving 93% of accuracy in the fake detection task, demonstrated the effectiveness of the proposed technique on a real-case scenario.

description: In the framework of the project SWELTO - Space WEather Laboratory in Turin Observatory, a fluxgate magnetometer has been procured, tested and characterized, and then installed and optimized in the INAF - Turin Astrophysical Observatory. This instrument aims to detect local geomagnetic disturbances associated with major global storms, providing a local value of the so-called Dst (i.e., Disturbance Storm Time) index. The measurements reported here and acquired during the first months after installation show a very good agreement with other similar instruments acquiring data in the surroundings, and also a good agreement with the official Dst-index provided by the World Data Center (WDC) for Geomagnetism, Kyoto.

description: Today the experience of beauty may be enjoyed by means of products that are not only artistic but also commercial and aesthetics is facing new horizons which include the experiences of everyday life. However, because of their prosaic character everyday objects have only rarely been at the centre of philosophical reflection. The aim of this issue of “Aisthesis” is to reflect with fruitful variety of approach on the epistemological status of the product, its value and significance in the light of the dialectics functionality/beauty, its relationship with the art work, and the new and specific conceptual paradigms that may offer an interpretive key.

description: We estimate a model of common and commodity-specific, high- and low-frequency factors, built on the spline-GARCH model of Engle and Rangel (2008) to explain the period of exceptionally high price volatility in commodity markets during 2006-2008. We find that decomposing realized volatility into high- and low-frequency components reveals the impact of slowly-evolving macroeconomic variables on the price volatility. Further, we find that while macroeconomic variables have similar effects within the same commodity category (e.g., storable agricultural), they have different effects across commodity groups (e.g., live stock versus energy).

description: In this paper, I defend the idea that the way we listen to improvisation depends on the very ontological nature of improvisation. More specifically, I argue that improvisation calls for an intentionalist listening, by which the listener follows the improvisation as the creative process that it is. This listening attitude is made possible by the heightening of musical experience inherent to the improvisational situation and by the empathy linking the audience to the improvisers – both the consequences of improvisation’s ontological and temporal structure.

description: The objective of this paper is to develop a model that explains the involvement of first level handlers in farm level decisions. In particular, the research attempts to explain observed differences among levels of farmer's autonomy in production contracts of different agricultural commodities. We show that the trade off that a contractor faces for holding the decision rights for controlling production inputs varies for different production environments. In particular, the contractor prefers controlling inputs in production of commodities that have relatively uniform production environments, whereas it is more efficient to delegate the control to the producer for commodities that have diverse production environments.

description: The Indian Integrated Child Development Services (ICDS) aims to improve the physical and psychological well-being of children younger than five. However, previous evaluations find that ICDS fails to significantly impact child stunting and that program placement is faulty. My results contradict the lack of a significant treatment effect, but are consistent with problematic program placement. Previous analyses of ICDS used probit to study placement, but the distribution of state-wise ICDS coverage is negatively skewed violating the normality assumption of probit. To address this, I use beta regression to study placement and compare results with probit analysis. In addition, using Propensity Score Matching (PSM) I find evidence of a significant, positive average and quantile treatment effects on stunting. Data are from the most recent Indian Family and Health Survey (NFHS-3).

Questo approccio mira a promuovere la missione dell'INAF, valorizzando i risultati scientifici e potenziando il dialogo con il pubblico e i media. Il documento propone buone pratiche per ottimizzare la gestione degli uffici stampa delle diverse sedi INAF. Una collaborazione stretta tra i referenti locali e l’Ufficio Stampa centrale è fondamentale per assicurare la tempestiva e coerente condivisione delle informazioni. A tal fine, viene suggerita la costituzione di un gruppo di lavoro INAF per coordinare gli uffici stampa delle sedi locali, con un rappresentante per ciascuna delle 16 sedi e del TNG, sotto la guida del Capo Ufficio Stampa della Struttura per la Comunicazione di Presidenza.

description: We discuss the phenomenological viability of string multi-Higgs doublet models, namely a scenario of heterotic $Z_3$ orbifolds with two Wilson lines, which naturally predicts three supersymmetric families of matter and Higgs fields. We study the orbifold parameter space, and discuss the compatibility of the predicted Yukawa couplings with current experimental data. We address the implications of tree-level flavour changing neutral processes in constraining the Higgs sector of the model, finding that viable scenarios can be obtained for a reasonably light Higgs spectrum. We also take into account the tree-level contributions to indirect CP violation, showing that the experimental value of $ε_K$ can be accommodated in the present framework.

description: The drivers of economic growth in what is called the New Economy has become an important policy question. As communities across the country face economic challenges and a new economic reality, the question of what works in the New Economy has emerged. This study aims to provide growth decomposition in the New Economy to identify key drivers of growth. It provides a conceptual, theoretical and empirical discussion of growth in the New Economy to solidify the theory and empirics of New Economy growth decomposition. Results suggest that growth in population, income and employment are mostly synergistic; innovation and talent are potent in the New Economy; population dynamics, especially in the young and retiree segment of the population are tied to local economic performance; housing market instability harms growth; green infrastructure assets enhance growth performance; and that economic legacy and entrenchment in the Old Economy can impact new growth potential. The framework, analysis and results in this study can provide the basis for further investigation in the area of New Economy growth accounting.

The composite material in question (lead sulphide nanocrystals in the conducting polymer MEH-PPV was made using a new single-pot, surfactant-free synthesis. Mobilties were measured using time of flight (ToF) and steady-state techniques. We have found that the inclusion of PbS nanocrystals in MEH-PPV both balances and markedly increases the hole and electron mobilities - the hole mobility is increased by a factor of ~105 and the electron mobility increased by ~107 under an applied bias of 5kVcm-1. These results explain why dramatic improvements in electrical conductivity and photovoltaic performance are seen in devices fabricated from these composites.

description: Planar germanium quantum wells have recently been shown to host hard-gapped superconductivity. Additionally, quantum dot spin qubits in germanium are well-suited for quantum information processing, with isotopic purification to a nuclear spin-free material expected to yield long coherence times. Therefore, as one of the few group IV materials with the potential to host superconductor-semiconductor hybrid devices, proximitized quantum dots in germanium is a compelling platform to achieve and combine topological superconductivity with existing and novel qubit modalities. Here we demonstrate a quantum dot (QD) in a Ge/SiGe heterostructure proximitized by a platinum germanosilicide (PtGeSi) superconducting lead (SC), forming a SC-QD-SC junction. We show tunability of the QD-SC coupling strength, as well as gate control of the ratio of charging energy and the induced gap. We further exploit this tunability by exhibiting control of the ground state of the system between even and odd parity. Furthermore, we characterize the critical magnetic field strengths, finding a critical out-of-plane field of 0.90(4). Finally we explore sub-gap spin splitting in the device, observing rich physics in the resulting spectra, that we model using a zero-bandwidth model in the Yu-Shiba-Rusinov limit. The demonstration of controllable proximitization at the nanoscale of a germanium quantum dot opens up the physics of novel spin and superconducting qubits, and Josephson junction arrays in a group IV material.

We analyse in detail the effect of three-loop running on the sparticle spectrum for the MSSM Snowmass Benchmark Points. We also consider the effect on these spectra of additional matter multiplets (the semi-perturbative unification scenario).

description: The focus of this paper is the topic of musical success and, more generally, of aesthetic success. Within the analytic aesthetics, the need to shift the musical experience on two floors, on two levels, it is increasingly evident. Sometimes, as in the case of those theories that defend a form of ontological realism, this dislocation ends up sacrificing the notion of experience. Can you speak of success within a theory of experience? In order to answer the question this paper attempts to create a dialogue between aesthetics and psychoanalysis.

An investigation into the mixed mode delamination behaviour of brittle composite laminates

description: Delamination is a prevalent composite laminate failure mode. It is of particular concern to the aerospace industry where laminated composites have found widespread usage in critical applications. Delamination growth has been widely studied, with Linear Elastic Fracture Mechanics (LEFM) being the most common approach taken to predict delamination behaviour, typically through global parameters such as specimen geometry and applied load measured away from the actual crack tip. However, internal mechanisms, such as fibre bridging, can occur within the structure thus affecting the transfer of the globally applied conditions to the actual crack tip. Thus, measurements made at the actual crack tip, referred to as local measurements, can be compared to the delamination behaviour predicted from the global analysis. The objective of this thesis is to better understand the relationship between the globally predicted and the actual local crack tip behaviour under mixed mode loading. Of particular interest is the mixed mode region at low shear (mode, II) loads where the global tensile opening (mode I) loads exceed the pure mode I fracture toughness of the material. An experimental loading j ig developed by Paris et al. (2001) is used in this work. The j ig can be used inside a scanning electron microscope (SEM) to allow for simultaneous local and global analysis of a specimen. Previous pure mode experiments (Paris, 1998) showed that in the absence of fibre bridging mode I global predictions match the actual local crack tip conditions. Global mode II loads, however, induce a local mixed mode condition where the mode I component is created due to the surface roughness as the crack surfaces slide over each other. In this work, mixed mode experiments on unidirectional AS4/3501-6 carbon fibre/epoxy laminates show that global applied shear loads are transferred directly to the crack tip. The crack surface roughness effects seen initially under pure mode II loading also manifest themselves under mixed mode loading resulting in a significantly higher local mode I component than predicted globally. As such, current test practices and global data reduction schemes are inadequate and do not provide a complete picture of delamination behaviour. The total local critical strain energy release rate is also significantly higher than that determined globally and observed in the literature. The higher local failure loads observed are consistent with fractographic evidence in the literature that indicates failure at the mixed mode conditions examined here is similar to much tougher mode II dominated failure.
Universal at last? The splashback mass function of dark matter halos

description: The mass function of dark matter halos is one of the most fundamental statistics in structure formation. Many theoretical models (such as Press-Schechter theory) are based on the notion that it could be universal, meaning independent of redshift and cosmology, when expressed in the appropriate variables. However, simulations exhibit persistent non-universalities in the mass functions of the virial mass and other commonly used spherical overdensity definitions. We systematically study the universality of mass functions over a wide range of mass definitions, for the first time including the recently proposed splashback mass, Msp. We confirm that, in LambdaCDM cosmologies, all mass definitions exhibit varying levels of non-universality that increase with peak height and reach between 20% and 500% at the highest masses we can test. Mvir, M200m, and Msp exhibit similar levels of non-universality. There are, however, two regimes where the splashback mass functions are significantly more universal. First, they are universal to 10% at z<2, whereas spherical overdensity definitions experience an evolution due to dark energy. Second, when additionally considering self-similar cosmologies with extreme power spectra, splashback mass functions are remarkably universal (to between 40% and 60%) whereas their spherical overdensity counterparts reach non-universalities between 180% and 450%. These results strongly support the notion that the splashback radius is a physically motivated definition of the halo boundary. We present a simple, universal fitting formula for splashback mass functions that accurately reproduces our simulation data.

description: This study takes an important first step at quantifying the nature of competition between major supermarket chains through price promotions. Using data that covers virtually the entire product menus of supermarkets representing two major chains in 18 cities, I examine both the effect of direct competition on promotional intensity and the nature of promotional competition itself. In a counterintuitive finding, there appears to slightly less promotional activity in cities in which both chains compete directly, as compared to cities in which only one chain operates. Moreover, most promotional activity tends to be retaliatory, rather than accommodating, in nature.

Musica e Weltanschauung. Opera musicale, filosofia, cultura

description: Can music express the world-view (Weltanschauung) of a certain composer, or of a certain historical era – and how? In 19th Century, the wide-ranging philosophical implications of this question raised an intriguing quarrel between the formalists’ scepticism as to this point and their various opponents. Starting from the case study of the German psychologist and philosopher of music Georg Anschütz (1886-1953), it is argued that allowing for a systematic link of music and the world-views easily turns into the far more demanding (and occasionally ambiguous) claim that music is the best and perhaps the only way to express them properly. In turn, this attitude sits well with the tendency to think of music hearing as a disembodied process, hinting at the deep dimension of synesthesia rather than to that of music as a cultural phenomenon, in Erich Hornbostel’s sense.

Fine structure of distributions and central limit theorem in diffusive billiards

description: We investigate deterministic diffusion in periodic billiard models, in terms of the convergence of rescaled distributions to the limiting normal distribution required by the central limit theorem; this is stronger than the usual requirement that the mean square displacement grow asymptotically linearly in time. The main model studied is a chaotic Lorentz gas where the central limit theorem has been rigorously proved. We study one-dimensional position and displacement densities describing the time evolution of statistical ensembles in a channel geometry, using a more refined method than histograms. We find a pronounced oscillatory fine structure, and show that this has its origin in the geometry of the billiard domain. This fine structure prevents the rescaled densities from converging pointwise to gaussian densities; however, demodulating them by the fine structure gives new densities which seem to converge uniformly. We give an analytical estimate of the rate of convergence of the original distributions to the limiting normal distribution, based on the analysis of the fine structure, which agrees well with simulation results. We show that using a Maxwellian (gaussian) distribution of velocities in place of unit speed velocities does not affect the growth of the mean square displacement, but changes the limiting shape of the distributions to a non-gaussian one. Using the same methods, we give numerical evidence that a non-chaotic polygonal channel model also obeys the central limit theorem, but with a slower convergence rate.

description: The development of groundwater-irrigated production technologies, fed by water from the Ogallala Aquifer, facilitated the development of agriculture in the High Plains region of the United States that began during the 1960s. The current rate of pumping for irrigation in the region is causing the aquifer to be depleted in many areas, which is cause for concern from a socioeconomic and environmental standpoint. The goal of this paper is to assess the factors that affect the decision to adopt groundwater-irrigated production by farmers, in the presence of risk differentiated by heterogeneous farmland quality and groundwater depth. A binary choice model of adoption is estimated for Nebraska, from 1960 – 2005. The results suggest that farmers consider climate variability, revenue potential, and potential pumping costs in the investment decision.

description: Quality of Experience (QoE) for various types of websites has gained significant attention in recent years. In order to design and evaluate websites, a metric that can estimate a user's experienced quality robustly for diverse content is necessary. SpeedIndex (SI) has been widely adopted to estimate perceived web page loading progress. It measures the speed of rendering pixels for the webpage that is visible in the browser window. This is termed Above-The-Fold (ATF). The influence of animated content on the perception of ATF has been less comprehensively explored. In this paper, we present an experimental design and methodology to measure ATF perception for websites with and without animated elements for various page content categories. We found that pages with animated elements caused people to have more varied perceptions of ATF under different network conditions. Animated content also impacts the page load estimation accuracy of SI for websites. We discuss how the difference in the perception of ATF will impact the QoE management of web applications. We explain the necessity of revisiting the visual assessment of ATF to include the animated contents and improve the robustness of metrics like SI.
