description: We aim to investigate the connections existing between the density profiles of the stellar populations used to define a gravitationally bound stellar system and their star formation history: we do this by developing a general framework accounting for both classical stellar population theory and classical stellar dynamics. We extend the work of Pasetto et al. (2012) on a single composite-stellar population (CSP) to multiple CSPs, including also a phase-space description of the CSP concept. In this framework, we use the concept of distribution function to define the CSP in terms of mass, metallicity, and phase-space in a suitable space of existence $\mathbb{E}$ of the CSP. We introduce the concept of foliation of $\mathbb{E}$ to describe formally any CSP as sum of disjointed Simple Stellar Populations (SSP), with the aim to offer a more general formal setting to cast the equations of stellar populations theory and stellar dynamics theory. In doing so, we allow the CSP to be object of dissipation processes thus developing its dynamics in a general non-Hamiltonian framework. Furthermore, we investigate the necessary and sufficient condition to realize a multiple CSP consistent with its mass-metallicity and phase-space distribution function over its temporal evolution, for a collisionless CSP. Finally, analytical and numerical examples show the potential of the result obtained.

residential property taxes

description: A major change of the property tax system in 2011 generated significant variation in the amount of housing taxes paid by Italian households. Using new questions added to the Survey on Household Income and Wealth (SHIW), we exploit this variation to provide an unprecedented analysis of the effects of property taxes on consumer spending. A tax on the main dwelling leads to large expenditure cuts among households with mortgage debt and low liquid wealth but generates only small revenues for the government. In contrast, higher tax rates on other residential properties reduce private savings and yield large tax revenues.
Faults Self-Organized by Repeated Earthquakes in a Quasi-Static Antiplane Crack Model

subject: FOS: Physical sciences

description: We study a 2D quasi-static discrete {\it crack} anti-plane model of a tectonic plate with long range elastic forces and quenched disorder. The plate is driven at its border and the load is transfered to all elements through elastic forces. This model can be considered as belonging to the class of self-organized models which may exhibit spontaneous criticality, with four additional ingredients compared to sandpile models, namely quenched disorder, boundary driving, long range forces and fast time crack rules. In this ''crack'' model, as in the ''dislocation'' version previously studied, we find that the occurrence of repeated earthquakes organizes the activity on well-defined fault-like structures. In contrast with the ''dislocation'' model, after a transient, the time evolution becomes periodic with run-aways ending each cycle. This stems from the ''crack'' stress transfer rule preventing criticality to organize in favor of cyclic behavior. For sufficiently large disorder and weak stress drop, these large events are preceded by a complex space-time history of foreshock activity, characterized by a Gutenberg-Richter power law distribution with universal exponent $B=1 \pm 0.05$. This is similar to a power law distribution of small nucleating droplets before the nucleation of the macroscopic phase in a first-order phase transition. For large disorder and large stress drop, and for certain specific initial disorder configurations, the stress field becomes frustrated in fast time : out-of-plane deformations (thrust and normal faulting) and/or a genuine dynamics must be introduced to resolve this frustration.

description: We investigate the effects of risk aversion on optimal transmission and generation expansion planning in a competitive and complete market. To do so, we formulate a stochastic model that minimizes a weighted average of expected transmission and generation costs and their conditional value at risk (CVaR). We show that the solution of this optimization problem is equivalent to the solution of a perfectly competitive risk-averse Stackelberg equilibrium, in which a risk-averse transmission planner maximizes welfare after which risk-averse generators maximize profits. This model is then applied to a 240-bus representation of the Western Electricity Coordinating Council, in which we examine the impact of risk aversion on levels and spatial patterns of generation and transmission investment. Although the impact of risk aversion remains small at an aggregate level, state-level impacts on generation and transmission investment can be significant, which emphasizes the importance of explicit consideration of risk aversion in planning models.

description: In recent years, geopolitical events have raised questions about the security of European energy supplies and which electricity generation technologies present an optimal fuel mix. Likewise, private investors need to allocate their capital efficiently by devising portfolios of generation assets. This paper applies the Modern Portfolio Theory to determine an optimal portfolio with four electricity generation technologies. Using UK electricity and fuel price data and European carbon allowance prices for the period 2009-2013, we find that coal assets increase portfolio risk and decrease overall returns, whilst a combination of gas, nuclear and wind assets allows an investor to maximise risk-adjusted return. In addition, we examine the role of power purchase agreements (PPAs) to assess whether predictable revenues create more appealing portfolio characteristics. We find that such contracts reduce portfolio returns, highlighting the importance of the set prices and their possible fluctuations over time. The findings support electricity market reform that discourages coal investment and supports investment in renewable technologies. The results also suggest that PPAs could make sense for independent renewable generators, although this would require modelling of the uncertainty of variable load factors and operating costs.
Energy efficiency and rebound effect in European road freight transport

description: Energy efficiency has become a primary energy policy goal in Europe and many other countries and has conditioned the policies towards energy-intensive sectors such as road freight transport. However, energy efficiency improvements can lead to changes in the demand for energy services that offset some of the expected energy savings in the form of rebound effects. Consequently, forecasts of energy savings can be overstated. This paper analyses the energy efficiency and rebound effects for road freight transport in 15 European countries during the 1992-2012 period. We use a recent methodology to estimate an energy demand function using a stochastic frontier analysis approach and examine the influence of key features of rebound effect in the road freight transport sector. We obtain on average a fuel efficiency of 91% and a rebound effect of 18%. Our results indicate that the achieved energy efficiencies are retained to a large extent. We also find, among other results, that the rebound effect is higher in countries with higher fuel efficiency and better quality of logistics. Finally, a simulation analysis shows significant environmental externalities costs even in countries with lower rebound effect.
Parity-violating quasifree electron-deuteron scattering in a covariant approach

description: The role of relativistic corrections associated with lower Dirac components of the deuteron wavefunction, is examined for parity-violating (PV) electron scattering. The relation between these corrections and negative energy components of the struck nucleon in relativistic PWIA is elucidated. The model dependence induced by describing such effects, using different deuteron vertex functions and prescriptions for the half-off-shell nucleon vertices, is compared against the precision required for studies of nucleon strangeness in quasielastic PV $e-d$ scattering.

Measuring LDA Topic Stability from Clusters of Replicated Runs

Publisher: name: arXiv
Year: 2018
Subjects: subject: Computation and Language (cs.CL)

description: Background: Unstructured and textual data is increasing rapidly and Latent Dirichlet Allocation (LDA) topic modeling is a popular data analysis methods for it. Past work suggests that instability of LDA topics may lead to systematic errors. Aim: We propose a method that relies on replicated LDA runs, clustering, and providing a stability metric for the topics. Method: We generate k LDA topics and replicate this process n times resulting in n*k topics. Then we use K-medioids to cluster the n*k topics to k clusters. The k clusters now represent the original LDA topics and we present them like normal LDA topics showing the ten most probable words. For the clusters, we try multiple stability metrics, out of which we recommend Rank-Biased Overlap, showing the stability of the topics inside the clusters. Results: We provide an initial validation where our method is used for 270,000 Mozilla Firefox commit messages with k=20 and n=20. We show how our topic stability metrics are related to the contents of the topics. Conclusions: Advances in text mining enable us to analyze large masses of text in software engineering but non-deterministic algorithms, such as LDA, may lead to unreplicable conclusions. Our approach makes LDA stability transparent and is also complementary rather than alternative to many prior works that focus on LDA parameter tuning.

Electricity network charging for flexibility

description: This paper discusses the principles of electricity network charging in the light of increasing amounts of distributed generation and the potential for significant increases in electric vehicles or distributed electrical energy storage. We outline cost reflective pricing, traditional public service pricing, platform market pricing and customer-focussed business model pricing. We focus on the particular problem of how to recover network fixed costs and a recent example from Australia. We conclude that there are serious issues for regulators to address, but that potential solutions at the distribution level may already exist at the transmission level.

description: We study total and partial supersymmetry breaking by freely acting orbifolds, or equivalently by Scherk-Schwarz compactifications, in type I string theory. In particular, we describe a four-dimensional chiral compactification with spontaneously broken N=1 supersymmetry, some models with partial $N=4\to N=2$ and $N=4\to N=1$ supersymmetry breaking and their heterotic and M-theory duals. A generic feature of these models is that in the gravitational sector and in the spectrum of D-branes parallel to the breaking coordinate, all mass splittings are proportional to the compactification scale, while global (extended) supersymmetry remains unbroken at tree level for the massless excitations of D-branes transverse to the breaking direction.

description: We carried out new observations of two fields in the northern ring of M31 with XMM-Newton with two exposures of 100 ks each and obtained a complete list of X-ray sources down to a sensitivity limit of ~7 x 10^34 erg s^-1 (0.5 - 2.0 keV). The major objective of the observing programme was the study of the hot phase of the ISM in M31. The analysis of the diffuse emission and the study of the ISM is presented in a separate paper. We analysed the spectral properties of all detected sources using hardness ratios and spectra if the statistics were high enough. We also checked for variability. We cross-correlated the source list with the source catalogue of a new survey of the northern disc of M31 carried out with Chandra and Hubble (Panchromatic Hubble Andromeda Treasury, PHAT) as well as with other existing catalogues. We detected a total of 389 sources, including 43 foreground stars and candidates and 50 background sources. Based on the comparison to the Chandra/PHAT survey, we classify 24 hard X-ray sources as new candidates for X-ray binaries (XRBs). In total, we identified 34 XRBs and candidates and 18 supernova remnants (SNRs) and candidates. Three of the four brightest SNRs show emission mainly below 2 keV, consistent with shocked ISM. The spectra of two of them also require an additional component with a higher temperature. The SNR [SPH11] 1535 has a harder spectrum and might suggest that there is a pulsar-wind nebula inside the SNR. We find five new sources showing clear time variability. We also studied the spectral properties of the transient source SWIFT J004420.1+413702, which shows significant variation in flux over a period of seven months (June 2015 to January 2016) and associated change in absorption. Based on the likely optical counterpart detected in the Chandra/PHAT survey, the source is classified as a low-mass X-ray binary.

description: This Consider an oligopolistic industry where two firms have access to the same technology and compete in prices, but one firm has access to better information about the customers in the market. We assume that better information allows the better informed firm to attract specific customers. The better informed firm obtains a first customer contact advantage, whereas the uninformed firm can only offer a menu of prices without being able to pre-identify the types of customers. We show that better information does not lead to higher profit.

À l’aide d’une revue de la littérature associée à une étude qualitative exploratoire auprès d’un échantillon de convenance de 29 personnes, les résultats révèlent que tous les aspects extrinsèque (économique, excellente et sociale) et intrinsèque (hédonique et spirituelle) de la valeur perçue sont présents dans la valorisation par le client de l’activité de magasinage, et ceci avec quelques spécificités comme les aspects détente, joie/plaisir et esthétique qui figure en premier plan, suivie de la recherche des économies en termes d’argent et de temps sont ceux qui poussent le plus les clients à fréquenter les enseignes dans les pays en développement. Par contre la valeur excellente bien que parfois très mal perçue revêt deux dimensions à savoir une liée aux produits commercialisés, l’autre à la praticité du point de vente (parking, sécurité mode de paiement). Les valeurs sociale et spirituelle, bien que présentant des citations faibles dans les propos des individus sont tout aussi importants pour certains consommateurs.

Vous seriez en droit de me faire une réprimande si je laissais partir Mme de Cannet pour Nîmes sans vous procurer le plaisir de la voir et de la connaître. c'est une citoyenne de Paris qui joint à beaucoup d'esprit et de talents naturels tout ce que l'éducation de cette belle ville peut donner de plus avantageux. Elle donne une preuve de son goût pour les arts en ne voulant pas quitter ces provinces sans voir ce que votre ancienne colonie contient de plus rare. Je me flatte que par une suite de votre estime pour les amateurs de l'Antiquité, vous voudrez bien lui montrer ce que votre cabinet contient de curieux et prier quelqu'un de vos élèves ou de vos amis de lui faire connaître les autres monuments distingués de votre belle ville. Je sais que c`aurait été vous faire de la peine autrefois que de vous demander de céder satisfaction à un autre, mais votre âge et vos incommodités autorisent vos amis à exiger aujourd'hui que vos politesses soient soumises [fol. 121 v] à une pareille condition.

J'ai été au reste longtemps sans vous écrire [tant] à cause de mes maladies habituelles que pour ne pas vous importuner à propos de peu de chose. Le R.P. Fabricy se porte bien. J'ai reçu depuis peu de ses nouvelles. Il est toujours infatigable et occupé à nous enrichir d'intéressantes découvertes. Il est nécessaire au bien public qu'il y ait des hommes qui, comme vous et lui, travaillent à la place de ceux qui comme moi n'ont que de la bonne volonté. Messieurs de Sainte-Croix et Calvet, avec lesquels je parle souvent de vous, se chargent à l'issue de ces conservations de me rappeler dans votre souvenir. Je ne perds jamais de vue les grandes bontés que vous avez eues pour moi. Je voudrais trouver l'occasion de vous témoigner les sentiments d'estime et de reconnaissance avec lesquels j'ai l'honneur d'être,

description: The most intensively star-forming galaxies are extremely luminous at far-infrared (FIR) wavelengths, highly obscured at optical and ultraviolet wavelengths, and lie at $z\ge 1-3$. We present a programme of ${\it Herschel}$ FIR spectroscopic observations with the SPIRE FTS and photometric observations with PACS, both on board ${\it Herschel}$, towards a sample of 45 gravitationally lensed, dusty starbursts across $z\sim 1-3.6$. In total, we detected 27 individual lines down to 3-$σ$, including nine $[\rm C{\small II}]$ 158-$μ$m lines with confirmed spectroscopic redshifts, five possible $[\rm C{\small II}]$ lines consistent with their far-infrared photometric redshifts, and in some individual sources a few $[\rm O{\small III}]$ 88-$μ$m, $[\rm O{\small III}]$ 52-$μ$m, $[\rm O{\small I}]$ 145-$μ$m, $[\rm O{\small I}]$ 63-$μ$m, $[\rm N{\small II}]$ 122-$μ$m, and OH 119-$μ$m (in absorption) lines. To derive the typical physical properties of the gas in the sample, we stack all spectra weighted by their intrinsic luminosity and by their 500-$μ$m flux densities, with the spectra scaled to a common redshift. In the stacked spectra, we detect emission lines of $[\rm C{\small II}]$ 158-$μ$m, $[\rm N{\small II}]$ 122-$μ$m, $[\rm O{\small III}]$ 88-$μ$m, $[\rm O{\small III}]$ 52-$μ$m, $[\rm O{\small I}]$ 63-$μ$m, and the absorption doublet of OH at 119-$μ$m, at high fidelity. We find that the average electron densities traced by the $[\rm N{\small II}]$ and $[\rm O{\small III}]$ lines are higher than the average values in local star-forming galaxies and ULIRGs, using the same tracers. From the $[\rm N{\small II}]/[\rm C{\small II}]$ and $[\rm O{\small I}]/[\rm C{\small II}]$ ratios, we find that the $[\rm C{\small II}]$ emission is likely dominated by the photo-dominated regions (PDR), instead of by ionised gas or large-scale shocks.

description: Including the vacuum effects, the compressional properties of nuclear matter are studied in the cutoff field theory. Under the Hartree approximation, the low-energy effective Lagrangian is derived in the framework of the renormalization group methods. The coefficients are determined in a way where the physical results hardly depend on the value of the cutoff which is conveniently introduced into the theory. It is shown that, to reproduce the empirical data of the nucleus incompressibility, the compressibility of the nuclear matter is favorable to be 250$\sim$350MeV.

description: We investigate the behaviour of the shortest path on a directed two-dimensional square lattice for bond percolation at the critical probability $p_c$ . We observe that flipping an edge lying on the shortest path has a non-local effect in the form of power-law distributions for both the differences in shortest path lengths and for the minimal enclosed areas. Using maximum likelihood estimation and extrapolation we find the exponents $α= 1.36 \pm 0.01$ for the path length differences and $β= 1.186 \pm 0.001$ for the enclosed areas.

description: We solve exactly a generalized Hubbard ring with twisted boundary conditions. The magnitude of the nearest-neighbor hopping depends on the occupations of the sites involved and the term which modifies the number of doubly occupied sites $t_{AB}=0$. Although $η$-pairing states with off-diagonal long-range order are part of the degenerate ground state, the behavior of the energy as a function of the twist rules out superconductivity in this limit. A small $t_{AB}$ breaks the degeneracy and for moderate repulsive $U$ introduce superconducting correlations which lead to ``anomalous'' flux quantization.

description: This study examined undergraduate, emerging-adult men and women between the ages of 18 and 30 and their dating partners. The AUDIT (Babor, Higgens-Biddle, Saunders, & Monteiro, 2001) was used to assess their own and their partners'eports ofhazardous alcohol misuse. Four types of couples were identified: alcohol misusing participants with alcohol misusing partners (i.e., alcohol concordant couples), alcohol misusing female participants with a non-alcohol misusing partner, alcohol misusing male participants with an non-alcohol misusing partner and non-alcohol misusing women and men (i.e., nonmisuse concordant couples). Participants and their relationship partners were also assessed for their status as an adult child of an alcoholic (ACOA) using the CAST-6 (Hodgins, Maticka-Tyndale, EI-Guebaly, & West, 1993). Alcohol concordant couples were compared to other couple types to examine possible differences in relationship satisfaction, alcohol consumption, and alcohol consequences. A chi-square test of independence was used to investigate whether one's own alcohol misuse is independent of partner alcohol concordance. It was expected that partners' alcohol misuse is not independent. This hypothesis was supported, indicating more risk for women to be in alcohol concordant relationships. In addition, it was expected that concordant couples would report greater alcohol consumption and consequences as compared to the other three couple types and higher relationship satisfaction as compared to discordant couples, but lower relationship satisfaction compared to non-misuse concordant couples. These hypotheses received partial support and important gender differences emerged. Non misuse concordant couples reported the highest degree of relationship satisfaction. Men' relationship satisfaction was uniformly higher than women's relationship satisfaction and alcohol misusing women had uniformly low satisfaction, regardless of whether they were in a relationship with an alcohol misusing partner. Regarding alcohol use, the alcohol misusing men but not the women in the couples have higher alcohol consumption and consequences by virtue of being in an alcohol concordant relationship. Another chi-square test was conducted to test whether alcohol concordance between couples differs as a function of ACOA status. ACOA status was unrelated to which type of alcohol concordance couple one was in.

description: We present a stochastic framework for emergent quantum gravity coupled to matter. The Hamiltonian constraint in diffeomorphism-invariant theories demands the identification of a clock relative to which dynamics may be defined, and other degrees of freedom can play the role of rulers. However, a global system of clock and rulers is generally not available. We provide evidence that stochasticity associated with critical points of clock and ruler fields can be related to the emergence of both a probabilistic description consistent with ordinary quantum theory, and gravitation described by general relativity at long distances. We propose a procedure for embedding any Lorentz-invariant field theory, including the Standard Model and its Lorentz-invariant extensions, in this framework.

A simple introduction to the economics of storage: shifting demand and supply over time and space

description: The literature on electrical energy storage (EES) is technical and complex which this paper aims to simplify. It quantifies the current scale, costs and value of different types of EES and compares them to peaking generators and interconnectors. Worldwide, dams have 2,700 times the storage capacity of pumped storage, which accounts for 99% of conventional EES, batteries making up the rest. Indirect use of hydro power, and in future, electric vehicles, adds to their value and if accessible at reasonable cost, would be cheaper than conventional EES. EES, peakers and DC interconnectors can offer flexibility services which considerably enhance their value, but hopes of a battery revolution enabling a smarter electricity system should not be exaggerated.

description: We investigate the finite-size scaling of the boundary quantum geometric tensor (QGT) numerically close to the Anderson localization transition in the presence of small external magnetic fields. The QGT exhibits universal scaling and reveals the crossover between the orthogonal and unitary critical states in weak random magnetic fields. The flow of the QGT near the critical points determines the critical exponents. Critical distributions of the QGT are universal and exhibit a remarkable isotropy even in a homogeneous magnetic field. We predict universal and isotropic Hall conductance fluctuations at the metal-insulator transition in an external magnetic field.

description: We show that the problem of solving recurrence relations for L-loop (R+1)-point Feynman integrals within the method of integration by parts is equivalent to the corresponding problem for (L+R)-loop vacuum or (L+R-1)-loop propagator-type integrals. Using this property we solve recurrence relations for two-loop massless vertex diagrams, with arbitrary numerators and integer powers of propagators in the case when two legs are on the light cone, by reducing the problem to the well-known solution of the corresponding recurrence relations for massless three-loop propagator diagrams with specific boundary conditions.

Renormalization effects in spin-polarized metallic wires proximitized by a superconductor: A scattering approach

description: Spin-polarized normal-metal wires coupled to a superconductor can host Majorana states at their ends. These decay into the bulk and are protected by a minigap in the spectrum. Previous studies have found that strong coupling between the superconductor and the normal-metal wire renormalizes the properties of this low-energy phase. Here, we develop a semiclassical scattering approach to explain these renormalization effects. We show that a renormalization of the propagation velocity in the normal wire originates from double Andreev reflection processes at the superconductor interface and that it continues to exist in the absence of a proximity-induced minigap in the normal-metal wire. We also show that the renormalization effects exist for arbitrary transparency of the normal-metal--superconductor interface, provided the superconductor coherence length is sufficiently long in comparison to the thickness of the normal metal.

Worker: Length 1.7-1.9 mm. - Compared with the original description and redescriptions and figures of Dr. W. M. Wheeler and Dr. Santschi and with a worker taken by myself on the island of St. Lucia, next island to the north
1) Many of these new forms were taken while I was the recipient of a National Research Council Fellowship in Biology with headquarters at the Imperial College of Tropical Agriculture, Trinidad, B. W. I. I am also indebted to the late Dr. W. M. Wheeler for aid in the determination of ants, particularly for determining many while I was living in Trinidad. My thanks are due Major J. F. Phipps, R. E., Chief Commissioner of the British Section of the British Guiana-BrazilSurinam Boundary Commission, for his kindness in affording me transportation by boat to the Commission Base Camp on the Oronoque River, British Guiana, in a region uninhabited and practically unexplored.
of the type locality, St. Vincent, the workers of this variety differ chiefly in sculpture. The anteriorly directed convex and blunt ridge between the anterior mesothoracic spines is more reduced or practically absent. Between the sharply carinate sides of the first gastric segment the surface is longitudinally and finely rugulose. Pale ferruginous. Spinosity as in the figure (Fig. 1).
Female: Length about 3.5 mm. - Similar to the worker, with the usual sexual differences. Dorsolaterally the pronotum bears on each side a pair of acute tubercles whose bases are confluent and the more posterior is the larger. Scutum in profile gently convex, from above slightly impressed medially, rugulose with finer reticulations between. Epinotal spines large and acute with stout bases, slightly diverging when viewed from above. Postpetiole from above roughly hexagonal with sides acutely angulate, 1.7 times as wide as long. Sculpturing heavier than in worker, color dark ferruginous with ferruginous appendages.
Described from one colony taken by myself June 23, 1935, in the Northern Range north of Arima, Trinidad, B. W. I., at an elevation of about 1800 feet. The species Js widely distributed in Trinidad but local and I have taken it in such representative localities as St. Augustine, Mayaro Bay, and Basin Holl Forest Reserve. The workers show sufficient variation to make identification uncertain without a knowledge of all three castes of the described varieties. To the distribution of this species may be added Antigua, B. W. I., (H. E. Box) and the Indian village of Apura on the Courantyne River, Surinam, by myself.

description: Even though the Drell-Yan-West formulation is the most rigorous and well-established framework to compute the exclusive processes, its utility has been limited only to the spacelike region because of the intrinsic kinematic constraint $q^+=0$. We present an explicit example demonstrating how one may obtain the necessary information (i.e. nonvalence or so called Z-graph contribution) in the timelike region of exclusive process without encountering a formidable task of direct calculation that has hindered so far the progress in this area. In the analysis of $q\bar{Q}$ bound state form factors using an exactly solvable model of $(3+1)$ dimensional scalar field theory interacting with gauge fields, the results analytically continued from the spacelike region coincide exactly with the direct results in the timelike region. This example verifies that the method of analytic continuation is capable of yielding the effect of complicate nonvalence contributions. The meson peaks analogous to the vector meson dominance(VMD) phenomena are also generated at the usual VMD positions.
