description: We apply the formalism of dynamical system analysis to investigate the evolution of interacting dark energy scenarios at the background and perturbation levels in a unified way. Since the resulting dynamical system contains the extra perturbation variable related to the matter overdensity, the critical points of the background analysis split, corresponding to different behavior of matter perturbations, and hence to stability properties. From the combined analysis, we find critical points that describe the non-accelerating matter-dominated epoch with the correct growth of matter structure, and the fact that they are saddle provides the natural exit from this phase. Furthermore, we find stable attractors at late times corresponding to a dark energy-dominated accelerated solution with constant matter perturbations, as required by observations. Thus, interacting cosmology can describe the matter and dark energy epochs correctly, both at the background and perturbation levels, which reveals the capabilities of the interaction.

description: With the growing amount of data, data processing workloads and the management of their resource usage becomes increasingly important. Since managing a dedicated infrastructure is in many situations infeasible or uneconomical, users progressively execute their respective workloads in the cloud. As the configuration of workloads and resources is often challenging, various methods have been proposed that either quickly profile towards a good configuration or determine one based on data from previous runs. Still, performance data to train such methods is often lacking and must be costly collected. In this paper, we propose a collaborative approach for sharing anonymized workload execution traces among users, mining them for general patterns, and exploiting clusters of historical workloads for future optimizations. We evaluate our prototype implementation for mining workload execution graphs on a publicly available trace dataset and demonstrate the predictive value of workload clusters determined through traces only.

Ergodicity breaking in wealth dynamics: The case of reallocating geometric Brownian motion

description: A growing body of empirical evidence suggests that the dynamics of wealth within a population tends to be non-ergodic, even after rescaling the individual wealth with the population average. Despite these discoveries, the way in which non-ergodicity manifests itself in models of economic interactions remains an open issue. Here, we shed valuable insight on these properties by studying the non-ergodicity of the population average wealth in a simple model for wealth dynamics in a growing and reallocating economy called Reallocating geometric Brownian motion (RGBM). When the effective wealth reallocation in the economy is from the poor to the rich, the model allows for the existence of negative wealth within the population. We show that then, in RGBM ergodicity breaks as the difference between the time-average and the ensemble growth rate of the average wealth in the population. In particular, the ensemble average wealth grows exponentially whereas the time-average growth rate is non-existent. Moreover, we find that the system is characterized with a critical self-averaging time period. Before this time period, the ensemble average is a fair approximation for the population average wealth. Afterwards, the non-ergodicity forces the population average to oscillate between positive and negative values since then the magnitude of this observable is determined by the most extreme wealth values in the population. This implies that the dynamics of the population average is an unstable phenomenon in a non-ergodic economy. We use this result to argue that one should be cautious when interpreting economic well-being measures that are based on the population average wealth in non-ergodic economies.

description: We present our determination of the baryon budget for an X-ray-selected XXL sample of 136 galaxy groups and clusters spanning nearly two orders of magnitude in mass ($M_{500}\sim 10^{13}-10^{15}M_\odot$) and the redshift range $0< z < 1$. Our joint analysis is based on the combination of HSC-SSP weak-lensing mass measurements, XXL X-ray gas mass measurements, and HSC and SDSS multiband photometry. We carry out a Bayesian analysis of multivariate mass-scaling relations of gas mass, galaxy stellar mass, stellar mass of brightest cluster galaxies (BCGs), and soft-band X-ray luminosity, by taking into account the intrinsic covariance between cluster properties, selection effect, weak-lensing mass calibration, and observational error covariance matrix. The mass-dependent slope of the gas mass--total mass ($M_{500}$) relation is found to be $1.29_{-0.10}^{+0.16}$, which is steeper than the self-similar prediction of unity, whereas the slope of the stellar mass--total mass relation is shallower than unity, $0.85_{-0.09}^{+0.12}$. The BCG stellar mass weakly depends on cluster mass with a slope of $0.49_{-0.10}^{+0.11}$. The baryon, gas mass, and stellar mass fractions as a function of $M_{500}$ agree with the results from numerical simulations and previous observations. We successfully constrain the full intrinsic covariance of the baryonic contents. The BCG stellar mass shows the larger intrinsic scatter at a given halo total mass, followed in order by stellar mass and gas mass. We find a significant positive intrinsic correlation coefficient between total (and satellite) stellar mass and BCG stellar mass and no evidence for intrinsic correlation between gas mass and stellar mass. All the baryonic components show no redshift evolution.

description: We use two available methods, the Duhem-Gibbs relation and the entropy formula in terms of particle phase space distributions, to calculate the entropy in a quark combination model. The entropy of the system extracted from the Duhem-Gibbs relation is found to increase in hadronization if the average temperature of the hadronic phase is lower than that of the quark phase. The increase of the entropy can also be confirmed from the entropy formula if the volume of the hadronic phase is larger than 2.5-3.0 times that of the quark phase. So whether the entropy increases or decreases during combination depends on the temperature before and after combination and on how much expansion the system undergoes during combination. The current study provides an example to shed light on the entropy issue in the quark combination model.

Stimulating the production of deeply bound RbCs molecules with laser pulses: the role of spin-orbit coupling in forming ultracold molecules

description: We investigate the possibility of forming deeply bound ultracold RbCs molecules by a two-color photoassociation experiment. We compare the results with those for Rb_2 in order to understand the characteristic differences between heteronuclear and homonuclear molecules. The major differences arise from the different long-range potential for excited states. Ultracold 85Rb and 133Cs atoms colliding on the X^1Sigma+ potential curve are initially photoassociated to form excited RbCs molecules in the region below the Rb(5S) + Cs(6P_1/2) asymptote. We explore the nature of the Omega=0^+ levels in this region, which have mixed A^1Sigma^+ and b^3Pi character. We then study the quantum dynamics of RbCs by a time-dependent wavepacket (TDWP) approach. A wavepacket is formed by exciting a few vibronic levels and is allowed to propagate on the coupled electronic potential energy curves. For a detuning of 7.5 cm-1, the wavepacket for RbCs reaches the short-range region in about 13 ps, which is significantly faster than for the homonuclear Rb_2 system; this is mostly because of the absence of an R^-3 long-range tail in the excited-state potential curves for heteronuclear systems. We give a simple semiclassical formula that relates the time taken to the long-range potential parameters. For RbCs, in contrast to Rb_2, the excited-state wavepacket shows a substantial peak in singlet density near the inner turning point, and this produces a significant probability of deexcitation to form ground-state molecules bound by up to 1500 cm-1. Our analysis of the role of spin-orbit coupling concerns the character of the mixed states in general and is important for both photoassociation and stimulated Raman deexcitation.

description: We study the finite-volume effects in our calculation of $B_K$ using HYP-smeared improved staggered valence fermions. We calculate the predictions of both SU(3) and SU(2) staggered chiral perturbation theory at one-loop order. We compare these to the results of a direct calculation, using MILC coarse lattices with two different volumes: $20^3$ and $28^3$. From the direct calculation, we find that the finite volume effect is $\approx 2%$ for the SU(3) analysis and $\approx 0.9%$ for the SU(2) analysis. We also show how the statistical error depends on the number of measurements made per configuration, and make a first study of autocorrelations.

description: This paper introduces a robust point-to-point transmission scheme: Tetrys, that relies on a novel on-the-fly erasure coding concept which reduces the delay for recovering lost data at the receiver side. In current erasure coding schemes, the packets that are not rebuilt at the receiver side are either lost or delayed by at least one RTT before transmission to the application. The present contribution aims at demonstrating that Tetrys coding scheme can fill the gap between real-time applications requirements and full reliability. Indeed, we show that in several cases, Tetrys can recover lost packets below one RTT over lossy and best-effort networks. We also show that Tetrys allows to enable full reliability without delay compromise and as a result: significantly improves the performance of time constrained applications. For instance, our evaluations present that video-conferencing applications obtain a PSNR gain up to 7dB compared to classic block-based erasure codes.

description: A binary star orbited by an outer companion constitutes a hierarchical triple system. The outer body may excite the eccentricity of the inner binary through the von~Zeipel-Lidov-Kozai (ZLK) mechanism, triggering the gravitational wave (GW) coalescence of the inner binary when its members are compact objects. Here, we study a sample of hierarchical triples with an inner black hole (BH) -- BH binary, BH -- neutron star (NS) binary, and BH -- white dwarf (WD) binary, formed via dynamical interactions in low-mass young star clusters. Our sample of triples was obtained self-consistently from direct N-body simulations of star clusters which included up-to-date stellar evolution. We find that the inner binaries in our triples cannot merge via GW radiation alone, and the ZLK mechanism is essential to trigger their coalescence. Contrary to binaries assembled dynamically in young star clusters, binary BHs merging in triples have preferentially low mass ratios (q ~ 0.3) and higher primary masses (m_p > 40 MSun). We derive a local merger rate density of 0.60, 0.11 and 0.5 yr^-1 Gpc^-3 for BH-BH, BH-NS and BH-WD binaries, respectively. Additionally, we find that merging binaries have high eccentricities across the GW spectrum, including the LIGO-Virgo-KAGRA (LVK), LISA, and DECIGO frequencies. About 7% of BH-BH and 60% of BH-NS binaries will have detectable eccentricities in the LVK band. Our results indicate that the eccentricity and the mass spectrum of merging binaries are the strongest features for the identification of GW mergers from triples.

description: We present infrared (IR) to X-ray spectral energy distributions (SEDs) for 44 red AGN selected from the 2MASS survey on the basis of their red J-K$_S$ color (>2 mag) and later observed by Chandra. In comparison with optically-, radio-, and X-ray selected AGN, their median SEDs are red in the optical and near-IR with little/no blue bump. It thus seems that near-IR color selection isolates the reddest subset of AGN that can be classified optically. The shape of the SEDs is generally consistent with modest absorption by gas (in the X-ray) and dust (in the optical-IR). The levels of obscuration, estimated from X-rays, far-IR and our detailed optical/near-IR color modeling are all consistent implying N_H < few*10^{22} cm^{-2}. We present SED models that show how the AGN optical/near-IR colors change due to differing amounts of reddening, AGN to host galaxy ratio, redshift and scattered light emission and apply them to the sources in the sample. We find that the 2MASS AGN optical color, B-R, and to a lesser extent the near-IR color, J-K$_S$, are strongly affected by reddening, host galaxy emission, redshift, and in few, highly polarized objects, also by scattered AGN light. The obscuration/inclination of the AGN allows us to see weaker emission components which are generally swamped by the AGN.

description: Digital competence has emerged as essential for employers and employees amid the digital transformation within organisations. This study referenced the European Union Digital Competency Framework 2.2 (DigComp 2.2) and assessed the digital competencies required for employment in the Ghanaian labour market. The “post-positivist” research collected and analysed data from 316 Ghana Employers Association member organisations. The findings revealed that communication and collaboration, information and data literacy, problem-solving and safety digital competencies are highly valued for first-entry recruitment and promotions. More than half of the organisations provide training in digital competency areas except for problem-solving and digital content creation. A chi-square test result indicated that digital competency areas utilised by organisations depended on the economy sector, even though each digital competency area is utilised for competitive advantage. The study results have managerial implications on digital transformation, recruitment and promotion of individuals with digital competencies, employability, human resource development and policy interventions.

description: We generalize the asymptotic shape theorem in first passage percolation on $\mathbb{Z}^d$ to cover the case of general semimetrics. We prove a structure theorem for equivariant semimetrics on topological groups and an extended version of the maximal inequality for $\mathbb{Z}^d$-cocycles of Boivin and Derriennic in the vector-valued case. This inequality will imply a very general form of Kingman's subadditive ergodic theorem. For certain classes of generalized first passage percolation, we prove further structure theorems and provide rates of convergence for the asymptotic shape theorem. We also establish a general form of the multiplicative ergodic theorem of Karlsson and Ledrappier for cocycles with values in separable Banach spaces with the Radon--Nikodym property.

È caratterizzato inevitabilmente da una sempre maggiore integrazione delle avanzate tecnologie digitali nelle strategie di marketing. Queste tecnologie vengono chiamate “Next Tech”, nome che ne racchiude una serie che tentano di riprodurre alcune capacità umane al fine di automatizzare i processi facilmente delegabili alle macchine per consentire ai marketer di concentrarsi sui compiti più importanti.  La collaborazione uomo-macchina è diventato un elemento chiave nel marketing moderno. L’Intelligenza Artificiale e i suoi principali sottoinsiemi come il Machine Learning, la rilevanza dei Big Data, il Cloud Computing, necessita di una corretta gestione e analisi, al fine di poter monitorare, migliorare e personalizzare la relazione con il cliente, anche nell’ambito dei loro dati raccolti durante le attività di marketing. L’acquisizione di dati personali da parte delle aziende e il loro utilizzo tramite software e tecnologie, apre moltissimi quesiti e timori riguardanti la loro protezione e la tutela della privacy dei consumatori. Sotto questo punto di vista la Comunità Europea sembra la più attenta a queste tematiche emanando il regolamento Digital Services Package.

description: Excerpts from the report Preface: Palms form an integral part of the native woody vegetation of the United States, especially the Southeast, and yet are known well to few persons living outside the areas where they grow. Wherever they are native or are cultivated outdoors in our country, they lend an air of tropical luxuriance and usually indicate a mild climate. Palm products from various parts of the world enter extensively into our modern economy. Most important are the oils from the fruits or seeds of palms such as coconut, African oilpalm, and babassu. Among their many other uses, these oils are employed in the manufacture of soap, edible products, cosmetics, tin cans, roofing plate, glycerine, and synthetic rubber. Wax from the leaves of carnauba is a basic ingredient of many kinds of polishes; it also plays a part in making carbon paper and phonograph records. Interest in the importance of palms in the world economy, especially oil-yielding species native to the Western Hemisphere, is increasing. This bulletin fills a gap in popularly available published information on an interesting group of tree species native to the United States.

description: The objective of the present article is to analyse the elements proposed by Celso Furtado regarding the process of overcoming underdevelopment – before and after “industrial civilization” – and to determine whether such attributes can characterize him as a neo(post)-Kaleckian. To accomplish this objective, we will carry out a detailed analysis of growth patterns led by profits and wages based on the neo-Kaleckian literature. The relationship between income distribution, demand, and capital accumulation was always present in Furtado's analyses, even before these approaches were formalised theoretically. This analysis is important to understand two main points of Furtado’s thought: i) the reason for Furtado's emphasis on distributive conflict as an engine of structural transformations and, in turn, as a driver of economic development; ii) the challenges imposed over underdeveloped economies in the face of a new world economic order, based on the increase in dependency relations as a result of the huge capital flows in the form of foreign direct investment of developed economies in underdeveloped regions.

The great calming and contemplation of Chih-I, chapter one: the synopsis (translated, annotated and with an introduction)
Creators: name: Donner, Neal Arvid
Publisher: name: University of British Columbia
Year: 2010

description: This thesis consists of an annotated translation, with introduction, of the first two of the ten rolls of the Mo-ho-chih-kuan The Mo-ho-chih-kuan is no. 1911 of the works contained in the Taisho edition of the Chinese Buddhist canon (Taisho-shinshu-daizokyo in Vol. 46 from page 1 to page 140. The first two rolls, Chapter One of the whole work, run from page 1 to page 21. The Mo-ho-chih-kuan derives from a series of lectures given over the summer months of the year 594 A.D. by the founder of the T'ien-t'ai school of Chinese Buddhism, Chih-I (538-597). Kuan-ting, a disciple of Chih-i, took notes on these lectures and subsequently revised and edited them until they reached approximately the form in which the text is now available. The Mo-ho-chih-kuan is devoted to the elucidation of meditation techniques and their philosophical underpinnings. This is apparent from the title alone, which I have rendered "The Great Calming and Contemplation," and which represents the Sanskrit maha-samatha-vipasyana. Chih and kuan are the two aspects of meditation for Chih-I and the T'ien-t'ai school, signifying the negative and the positive approaches to religious practise: on the one hand the mental defilements, illusions and errors must be calmed, halted and eradicated (chih), and on the other hand the practitioner views, contemplates and has insight into (kuan ) the nature of Ultimate Reality. "Calming" (ohih) is quieting the mind, contemplation (kuan) is making it work properly. What I have undertaken to translate is the first chapter of the whole work, the Synopsis. This chapter may be considered a reduced-size version of the whole, though it also contains much material that is either not in the other chapters or is there presented in a different way. It is best known for its exposition of the "Four Kinds of Samadhi" or programs of religious practise: the constantly-sitting samadhi, the constantly-walking samadhi, the half-walking/half-sitting samadhi, and the neither-walking-nor-sitting samadhi. These involve respectively sitting quietly in the lotus posture, walking while reciting the name of the Buddha Amitabha, pronouncing dhavanls while alternating between sitting and walking, and using one's every thought and every act for contemplation. The author Chih-i classifies meditation (calming-and-contemplation) into three types: the gradual, the variable and the sudden. The Mo-ho- chih-kuan deals with the "sudden" variety, in which the practitioner's identity with Ultimate Reality is recognized from the very beginning of his religious practise. This form of meditation is consistent with the Mahayana Buddhist position that there is no ontological difference between the defilements of mind and enlightenment: there is nothing that does not enter into the nature of the Real. This chapter may be considered

description: The unconventional superconductivity in the newly discovered iron-based superconductors is intimately related to its multi-band/multi-orbital nature. Here we report the comprehensive orbital characters of the low-energy three-dimensional electronic structure in BaFe$_{1.85}$Co$_{0.15}$As$_2$ by studying the polarization and photon energy dependence of angle-resolved photoemission data. While the distributions of the $d_{xz}$, $d_{yz}$, and $d_{3z^2-r^2}$ orbitals agree with the prediction of density functional theory, those of the $d_{xy}$ and $d_{x^2-y^2}$ orbitals show remarkable disagreement with theory. Our results point out the inadequacy of the existing band structure calculations, and more importantly, provide a foundation for constructing the correct microscopic model of iron pnictides.

description: This paper introduces the notion of monetary disorder. The underlying theory rests on a twin circuits view of the macro economy. The idea of monetary disorder has relevance for understanding the experience and consequences of the recent decade-long period of monetized large budget deficits and ultra-easy monetary policy. Current policy rests on Keynesian logic whereby a large fall in aggregate demand warrants robust offsetting monetary and fiscal policy actions. That logic neglects potential monetary disorder being bred within the financial circuit in the form of inflated asset prices and leveraged balance sheets. That disorder is likely to develop long before inflation accelerates so that inflation targeting fails to protect against it. Political factors increase the policy danger as the benefits of disorder are front-loaded and the costs backloaded. The paper concludes with a policy discussion regarding how to prevent Keynesian goods market counter-cyclical stabilization policy from causing monetary disorder.

description: This paper tries to highlight some essential elements that emerge from Luigi Pasinetti’s work. Much of the research project that Pasinetti developed, especially in the 1981 book, was already present in nuce in the 1974 collection of essays. Here the theory of effective demand is presented for the first time, emphasizing the essential differences between sequential and simultaneous economic reasoning. The relevance of structural change is already apparent, and will be explored in a multisectoral scheme only in the 1981 book. The main insights that can be drawn from Pasinetti’s reflections on open economic systems and his ethical stance suggest that ownership of the means of production not only confers rights but it also imposes responsibilities on the community.

description: We discuss epistemological and methodological aspects of the Bayesian approach in astrophysics and cosmology. The introduction to the Bayesian framework is given for a further discussion concerning the Bayesian inference in physics. The interplay between the modern cosmology, Bayesian statistics, and philosophy of science is presented. We consider paradoxes of confirmation, like Goodman's paradox, appearing in the Bayesian theory of confirmation. As in Goodman's paradox the Bayesian inference is susceptible to some epistemic limitations in the logic of induction. However Goodman's paradox applied to cosmological hypotheses seems to be resolved due to the evolutionary character of cosmology and accumulation new empirical evidences. We argue that the Bayesian framework is useful in the context of falsificability of quantum cosmological models, as well as contemporary dark energy and dark matter problem.

effect of reducing wages of remote workers on society. A preliminary assessment

description: Remote work has represented ‘the’ alternative to office work during the COVID-19 pandemic as it has (while enabling employees to fulfill tasks from home) prevented or broken contagion chains. Though not a new approach to work, the recent emphasis on telework has come with pleas to reduce the wages of remote workers. By means of a logical-analytical approach, the article analyzes why such policies are not only unjustifiable in terms of keeping average wages at an at least stable level, but even more if the final sales prices would not shrink accordingly and would boost the share of corporate profits to GDP. Even cutting wages and final sales could be “deflationary” first and “recessionary” then (i.e., impoverish the economy). The article preliminarily analyzes the economic impact of such proposals on countries with a large ICT sector contributing to GDP (i.e., where remote work is facilitated due to the wide diffusion of tools such as Internet connections, computer devices, etc., enabling it) and an underperforming labor market in terms of female participation.

description: The quantum Hall effect in a single-layer graphene sample is studied in strong magnetic fields up to 28 T. Our measurements reveal the existence of a metal- insulator transition from filling factor $ν=-2$ to $ν=0$. The value of the universal scaling exponent is found to be $κ=0.57 $ in graphene and therefore in a truly two-dimensional system. This value of $κ$ is in agreement with the accepted universal value for the plateau-insulator transitions in standard quasi two-dimensional electron and hole gases.

One loop matching factors for staggered bilinear operators with improved glue

description: We present results for matching factors for bilinear operators composed of HYP-smeared staggered fermions and constructed using HYP-smeared fat links. The matching factors are calculated perturbatively at one-loop order. The new feature of our calculation compared to previous work on HYP-smeared staggered fermions is the use of the Symanzik-improved gluon propagator, which allows our results to be applied to our ongoing simulations based on configurations generated by the MILC collaboration. We address the issue of the relative efficiency of various improvement schemes in reducing one-loop corrections to the matching factors.

description: In this paper we introduce the class of W_p scale mixture random vectors with a particular radial decomposition and a independent splitting property specified by some random variable W_p, and a positive constant p. We derive several conditional limit results assuming that the distribution of the random radius is in the max-domain of attraction of a univariate extreme value distribution and W_p has a certain tail asymptotic behaviour. As an application we obtain the joint asymptotic distribution of concomitants of order statics considering certain bivariate W_p scale miture samples.
