description: In order to evaluate the response to cosmic-ray nuclei of a Compton-Scatter Transition Radiation Detector in the proposed ACCESS space-based mission, a hybrid Monte Carlo simulation using GEANT3 and an external transition radiation (TR) generator routine was constructed. This simulation was employed to study the effects of delta-ray production induced by high-energy nuclei and to maximize the ratio of TR to delta-ray background. The results demonstrate the ability of a Compton-Scatter Transition Radiation Detector to measure nuclei from boron to iron up to Lorentz factors ~ 10^5 taking into account the steeply falling power-law cosmic ray spectra.

description: We perform theoretical calculations to obtain a distribution of local d-wave superconducting gaps $Δ_0({r})$ for a high temperature superconducting (HTSC) series in a disordered superconductor with an average doping level $$. To reproduce the inhomogeneous medium a nonmagnetic random potential $V^{imp}$, within a Bogoliubov-de Gennes (BdG) formalism, is considered. First the phase diagram $Δ_0 x $ for the LSCO HTSC series, with V^{imp}=0, is obtained. Then, we perform calculations considering a fixed value of the disorder strength $V^{imp}$ and obtain a distribution of local superconducting gaps $Δ_0({r})$, and local density of charge carriers $ρ({r})$. It is shown that the underdoped compounds are more inhomogeneous than the overdoped ones, which is in accordance with experimental findings. Also, the spatial variation of $Δ_0({r})$ indicates that as increases, the system becomes more homogeneous.

The ‘Italian’ Castellet
Creators: name: Luti, Francesco
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2015

description:

This paper seeks to recall the ‘Italian route’ of the critic Josep Maria Castellet in the last century, a key figure in Spanish and Catalan literature. The Italian publishing and literary worlds served as a point of reference for Castellet, and also for his closest literary companions (José Agustín Goytisolo and Carlos Barral). All of these individuals formed part of the so-called Barcelona School. Over the course of at least two decades, these men managed to build and maintain a bridge to the main Italian publishing houses, thereby opening up new opportunities for Spanish literature during the Franco era. Thanks to these links, new Spanish names gained visibility even in the catalogues of Italian publishing houses. Looking at the period from the mid- 1950s to the end of the 1960s, the article focuses on the Italian contacts of Castellet as well as his publications in Italy. The study concludes with a comment on his Latin American connections, showing how this literary ‘bridge’ between Barcelona and Italy also contributed to exposing an Italian audience to the Latin American literary boom.

A Protocol for the Inflected Construction in Sicilian Dialects
Creators: name: Giusti, Giuliana
name: Di Caro, Vincenzo Nicolò
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2015

description:

Most Sicilian dialects display a monoclausal construction with a functional verb (usually of motion), followed by the linking element a and a lexical verb called Inflected Construction by Cardinaletti, Giusti (2001, 2003). This construction shows a high degree of cross-linguistic variation. The aim of the paper is to propose the protocols in the sense of Giusti, Zegrean (2015) to conduct fieldwork in this area. Protocol Linguistics is a metamodel of linguistic research that can be shared by linguists of different theoretical persuasion, can be accessible to non-linguists, and is meant to interface with a number of disciplines and environments such as social sciences and political planning, neuro-psychology and language rehabilitation, pedagogy and language education. The protocols consist of simple table-charts with the horizontal axis listing the empirical environments to be searched, e.g. the languages to be compared, and the vertical axis listing (clusters of) properties, named features, to be valued as +/- according to whether they are present or absent in each environment. The features relevant to the investigation on the Inflected Construction rely on preliminary work by Di Caro (2015), which highlights a finer grained variation than the one presented in previous literature (a.o. Cardinaletti, Giusti 2001, 2003, and Cruschina 2013). In the spirit of the principles-and-parameters approach, the protocols for the Inflected Construction are clustered around two main dimensions, each involving clusters of properties: (i) the lexical restrictions on the functional and/or the lexical verb; (ii) the person, tense and mood restrictions of the verbal paradigm.

VoiceP Deactivation and Deponency in Latin
Creators: name: Pinzin, Francesco
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2015

description:

What is a deponent verb? Why do we have verbs which have only a Non Active morphology and never an Active one? Is it possible to these verbs as a coherent category, with a common feature? Is this common feature a syntactic one, a semantic one or a morphological one? I’m trying to propose a (partial) answer to these questions. To do that, I have analysed the most salient and representative Latin deponent verbs in the Latin texts of the first century BCE. The proposed analysis is a syntactic-semantic one. The issue of deponent verbs is inextricably bound to the Latin passive morphology (-r). I claim that -r is a Voice° deactivator, like German sich in anticausatives and middles and Italian si. This analysis is sustained by its distribution and syntactic-semantic features. A deactivated Voice° can convey an anticausative interpretation, a middle-passive or a reflexive (through Argument Identification). The only productive class of deponents in Latin is the denominal one and there is an obvious relationship between Voice° deactivation and deponents. In the derivation(s) of denominal deponents a deactivated Voice° is needed. Without it the Int Arg, merged with the verbalized noun (nP), could not gain the Ext Arg (initiator) semantics. The bridge between these two positions is built by Argument Identification, a semantic mechanism that relies on the presence of the deactivated Voice° and, consequently, on the -r morphology.

Sexual behaviour enhancing effects of melatonin
Creators: name: Brotto, Lori Anne
Publisher: name: University of British Columbia
Year: 2009

description: Anecdotal reports suggest that melatonin enhances libido in men. However, controlled trials remain to be published for any species. Accordingly, male rats were chronically treated for 12 weeks with melatonin via the drinking water. All aspects of sexual activity, including measures of both libido and potency, were significantly facilitated. In addition, there was a consistent, progressive reduction in the frequency of wet dog shake behaviour, suggestive of a temporal decrement in serotonergic receptor activity. To date, this is the first empirical report of a facilitatory role for melatonin in sexual behaviour.

description: The increased social media attention to scholarly articles has resulted in efforts to create platforms & services to track and measure the social media transactions around scholarly articles in different social platforms (such as Twitter, Blog, Facebook) and academic social networks (such as Mendeley, Academia and ResearchGate). Altmetric.com and PlumX are two popular aggregators that track social media activity around scholarly articles from a variety of social platforms and provide the coverage and transaction data to researchers for various purposes. However, some previous studies have shown that the social media data captured by the two aggregators have differences in terms of coverage and magnitude of mentions. This paper aims to revisit the question by doing a large-scale analysis of social media mentions of a data sample of 1,785,149 publication records (drawn from multiple disciplines, demographies, publishers). Results obtained show that PlumX tracks more wide sources and more articles as compared to Altmetric.com. However, the coverage and average mentions of the two aggregators vary across different social media platforms, with Altmetric.com recording higher mentions in Twitter and Blog, and PlumX recording higher mentions in Facebook and Mendeley, for the same set of articles. The coverage and average mentions captured by the two aggregators across different document types, disciplines and publishers is also analyzed.

description: The present study sets up a thought experiment calibrated to represent risks of a high-risk production activity (farming), and investigating whether the structure of risk aversion (i.e., the changes in absolute or relative risk aversion associated with changes in wealth) can be estimated with reasonable precision. Findings strongly suggest that typical production data are unlikely to allow identification of the structure of risk aversion. A flexible utility parameterization is found to worsen technology parameter estimates. Findings also indicate that even under a restricted utility specification, the quality of utility parameters estimated from small samples is very poor.

description: Although there are numerous studies of the aggregate impact of trade liberalization on WANA countries, few studies have examined the impact of trade liberalization on the agricultural sector and on income distribution. This study attempts to address this gap in the literature. First, we review agricultural trade patterns and previous research on thirteen WANA countries: Morocco, Algeria, Tunisia, Egypt, the West Bank and Gaza, Lebanon, Jordan, Syria, Turkey, the Sudan, Somalia, Djibouti, and Yemen. Second, we examine the distributional impact of agricultural trade liberalization in three of these countries: Tunisia, Egypt, and Syria. For this analysis we use a combination of household survey data and computable general equilibrium (CGE) models. Third, we explore some of the reasons that these analyses show a relatively modest effect of trade policy on farm income and poverty.

description: We study the entanglement dynamics in a generic quantum automaton circuit subjected to projective measurements. We design an efficient algorithm which not only allows us to perform large scale simulation for the Rényi entropy but also provides a physical picture for the entanglement dynamics, which can be interpreted in terms of a classical bit-string model which belongs to the directed percolation universality class. We study the purification dynamics of a state formed by EPR pairs, and the growth of entanglement starting from a product state. In both cases, we verify numerically that the dynamics is in the universality class of classical directed percolation.

description: More than 50 percent of current farmers are over age 55, and the number of new farmers replacing them has fallen. This paper examines factors that contribute to the financial performance of new and beginning farmers in the U.S. A weighted regression analysis was used on data from the 2005 Agricultural Resource Management Survey (ARMS) to measure new and beginning farmers' financial performance given farm and operator characteristics, production and marketing, and risk management strategies. Particular attention was given to the impact of technology adoption and management strategy on financial performance. Results indicate the adoption of Genetically Modified (GM) crops, having a written business plan, controlling variable costs, participation in coupled farm program payment, and participation in marketing contracts lead to higher financial performance while education, age, and off-farm work lowered financial performance for new and beginning farmers.

description: This document presents the results of the second evaluation and validation iteration of the CAPABLE prototypes as defined in previous deliverable D7.1. In this validation process, an updated version of the WP6 prototype has been evaluated
 applying the two methods presented in D7.1: Interviews with patients and relatives. These interviews aimed to collect feedback from the end-users of the Patient App: melanoma and kidney cancer patients during the treatment phase. Given the broader applicability of the app to any type of cancer patient, this iteration included also other types of oncological patients, cancer survivors (treatment finished since no more than 2 years), and experts in patients’ needs, such as caregivers. Overall, 17 patients and 2 caregivers have been interviewed. Interviews with healthcare professionals (HCPs). These interviews aimed to collect overall feedback about both doctors’ and patients’ solutions, understand if the clinical and patients’ needs are covered, and revise the core functionalities that have been proposed in the current prototype. A total of 11 health professionals have been interviewed. We present the results of the 2 executed studies. The protocols of each study are attached in the annex. The document also presents the general conclusions from these validation activities and the next steps to follow in the future developments in order to satisfy the user experience needs found in this process.

description: Although comanagement is gaining increasing attention as a way to manage fisheries, few studies have attempted to understand quantitatively which factors of comanagement are critical for their success. This study investigates fishery comanagement regimes adopted by coastal fisheries in Japan. Utilizing a wide variety of examples of fishery comanagement nationwide, we search for key rules and measures that underlie traditional, cultural, and social aspects of comanagement. The study focuses on the rules of the game adopted by comanaging groups called fishery management organizations (FMOs). Upon examination of successful fishery comanagement cases, we found two distinctive measures: effort coordination and pooling arrangements. Furthermore, anecdotal evidence suggests that pooling arrangements are vital supporting measure for effective effort coordination, in which case having both of these two measures rather than only either one may be the key for successful fishery comanagement. We test this hypothesis with two sets of data. One is Japan's fishery census, which was published by the government and offers a large sample size but lacks information on effort coordination. Another is data from a survey designed and conducted by the authors to supplement the information on effort coordination and other self-imposed regulations. Our results show that (1) merely establishing comanaging groups such as FMOs has limited effect; (2) FMOs that establish pooling arrangements earn greater revenue from their fishing efforts, particularly when such pooling arrangements are combined with effort-coordination; and (3) pooling arrangements and effort coordination coupled with marketing activities result in the greatest revenue.

description: We present an empirical method for estimating the underlying redshift distribution N(z) of galaxy photometric samples from photometric observables. The method does not rely on photometric redshift (photo-z) estimates for individual galaxies, which typically suffer from biases. Instead, it assigns weights to galaxies in a spectroscopic subsample such that the weighted distributions of photometric observables (e.g., multi-band magnitudes) match the corresponding distributions for the photometric sample. The weights are estimated using a nearest-neighbor technique that ensures stability in sparsely populated regions of color-magnitude space. The derived weights are then summed in redshift bins to create the redshift distribution. We apply this weighting technique to data from the Sloan Digital Sky Survey as well as to mock catalogs for the Dark Energy Survey, and compare the results to those from the estimation of photo-z's derived by a neural network algorithm. We find that the weighting method accurately recovers the underlying redshift distribution, typically better than the photo-z reconstruction, provided the spectroscopic subsample spans the range of photometric observables covered by the photometric sample.

description: Unlike traditional demographic variables that are based on individual characteristics, social network analysis examines the various relationships between people. The basis of network analysis is to understand how actors are located within a network. Self reported data is collected to describe the degree of the knowledge and trust between each pair of participants in this study. Using methods from graph theory the resulting matrices are analyzed resulting in the assignment of degrees of connection among the participants. This research tests whether social networks can be used to predict food product adoption in a multi-country setting. The goal of this paper is to determine if variables that represent different aspects of group structure can better explain why some participants choose to adopt new food products, while others do not.

description: The paper presents a comparative analysis of the productivity of corporate and individual farms in Ukraine based primarily on cross-section data from a farm survey conducted by FAO in 2005. We calculate partial land and labor productivity, total factor productivity, and technical efficiency scores (using Stochastic Frontier Analysis) for farms of different organizational forms. Our results demonstrate with considerable confidence that, contrary to established convictions among the Ukrainian decision makers, the large corporate farms are not more productive than the smaller family farms. This finding is not restricted to Ukraine, as a similar result has been obtained by in Moldova, Russia, and the U.S. Policies encouraging a shift from large corporate farms to smaller individual farms, rather than the reverse, can be expected to produce beneficial results for Ukrainian agriculture and the economy in general. The government of Ukraine should abandon its inherited preference for large-scale corporate farms and concentrate on policies to improve the operating conditions for small individual farms. At the very least, the government should ensure a level playing field for farms of all sizes and organizational forms, and desist from biasing its policies in favor of large farms.

description: Traditionally, Web of Science and Scopus have been the two most widely used databases for bibliometric analyses. However, during the last few years some new scholarly databases, such as Dimensions, have come up. Several previous studies have compared different databases, either through a direct comparison of article coverage or by comparing the citations across the databases. This article attempts to compare the journal coverage of the three databases: Web of Science, Scopus and Dimensions. The most recent master journal lists of the three databases have been used for the purpose of identifying the overlapping and unique journals covered in the databases. The results indicate that the databases have significantly different journal coverage, with the Web of Science being most selective and Dimensions being the most exhaustive. About 99.11% and 96.61% of the journals indexed in Web of Science are also indexed in Scopus and Dimensions, respectively. Scopus has 96.42% of its indexed journals also covered by Dimensions. Dimensions database has the most exhaustive coverage, with 82.22% more journals covered as compared to Web of Science and 48.17% more journals covered as compared to Scopus. We also analysed the research outputs for 20 highly productive countries for the 2010-2019 period, as indexed in the three databases, and identified database-induced variations in research output volume, rank and global share of different countries. In addition to variations in overall coverage of research output from different countries, the three databases appear to have differential coverage of different disciplines.

Productivity of western larch in relation to categorical measures of climate, soil moisture, and soil nutrients
Creators: name: New, David Morley
Publisher: name: University of British Columbia
Year: 2009

description: The relationship between western larch (Larix occidentalis Nutt.) productivity, as determined by site index, and estimates of climate, soil moisture and soil nutrients, as delineated within the Biogeoecosystem classification system, was examined. Data was collected from 315 even-aged stands throughout the range of western larch in B.C. Climate, expressed by subzone, showed a significant effect on the site index of western larch; however, significant differences occurred only between two groups: lower precipitation (Interior Douglas-fir) and higher precipitation (Interior Cedar - Hemlock and Montane Spruce ) subzones. The climatic growth optimum for western larch corresponded to the intermediate segment of a regional climatic gradient - wetter temperate climate - that is represented by the Dry Warm Interior Cedar - Hemlock subzone. In relation to edatopes, site index significantly increased from water-deficient to moist sites and decreased from moist to wet sites, and on water-deficient sites, it increased with increasing soil nutrient regime. On water-deficient sites, estimates of both actual soil moisture regime and soil nutrient regimes had both positive significant and consistent effects on site index. On non-water deficient sites, the effect of soil nutrient regime appeared to be marginal. A cross-validated prediction model based on actual soil moisture regime and soil nutrient regime accounted for 83% of the variation in site index of western larch suggesting that there is a strong correlation between ecological site classification and western larch productivity. The developed model, combined with the identification of actual soil moisture regime, and soil nutrient regime can be used to provide reliable site index predictions for western larch throughout its range in B.C. to a level of accuracy required for practical forest management.
Search for Planetary Candidates within the OGLE Stars

description: We propose a method to distinguish between planetary and stellar companions to stars which present a periodic decrease in brightness, interpreted as a transit. Light curves from a total of 177 stars from the OGLE project were fitted by the model which simulates planetary transits using an opaque disk in front of an image of the Sun. The simulation results yield the orbital radius in units of stellar radii, the orbital inclination angle, and the ratio of the planet to the star radii. Combining Kepler's third law with a mass-radius relation for main sequence stars, it was possible to estimate values for the masses and radii of both the primary and secondary objects. This model was successfully tested with the confirmed planets orbiting the stars HD 209458, TrES-1, OGLE-TR-10, 56, 111, 113, and 132. The method consists of selecting as planetary candidates only those objects with primary densities between 0.7 and 2.3 solar densities (F, G, and K stars) and secondaries with radius less than 1.5 Jupiter radius. The method is not able to distinguish between a planet and a dwarf star with mass less than 0.1 $M_\odot$, such as OGLE-TR-122. We propose a selection of 28 planetary candidates (OGLE-TR-49, 51, 55, 63, 71, 76, 90, 97, 100, 109, 114, 127, 130, 131, 134, 138, 140, 146, 151, 155, 159, 164, 165, 169, 170, 171, 172, and 174) for high resolution spectroscopy follow up.

These findings are based on an analogy with known relations between Potts and O(n) models, and on an exact solution of a 'tri-tricritical' Potts model described in the literature. We verify the exact expressions for the tricritical O(n) model by means of a finite-size scaling analysis based on numerical transfer-matrix calculations.

description: The photoisomerization of chromophores embedded in biological environments is of high importance for biomedical applications, but it is still challenging to define the photoisomerization mechanism both experimentally and computationally. We present here a computational study of the azobenzene molecule embedded in a DPPC lipid membrane, and assess the photoisomerization mechanism by means of the quantum mechanics/molecular mechanics surface hopping (QM/MM-SH) method. We observe that while the trans-to-cis isomerization is a slow process governed by a torsional mechanism due to the strong interaction with the environment, the cis-to-trans mechanism is completed in sub-ps time scale and is governed by a pedal-like mechanism in which both weaker interactions with the environment and a different geometry of the potential energy surface play a key role.
Linguacultural identity paths in the blog Me4Change

description: The debate on migration, identity and power has been thriving over the last decades. It is now a priority not only in the context of current television programmes and talk shows but also across different genres and social media, among which a pivotal role is played by websites and blogs. In the latter, the issues of identity, power, contact and belonging come into play more than in any other domain, pushing us towards ‘translanguaging’ ethnographies and ‘superdiversity’ (Blommaert and Rampton 2011), as well as to new forms of discourse which result from a process of complex adaptation (Larsen-Freeman and Cameron 2008). The aim of this paper is to gain some insights into the use of language as a means of identity expression on the part of migrants belonging to different lingua-cultural backgrounds. More specifically, we propose some excerpts taken from the website and blog Me4Change as expression of transnational uses of English as a Lingua Franca (Seidlhofer 2003, 2011) at both linguistic and multimodal level. The analysis of case studies taken from the corpus is meant to add new points for discussion to the already-existing literature on English as a Lingua Franca (ELF) variations and highlight new features for its creative use, which are beyond any regional and national boundaries. The contribution is also meant to provide additional tools for the interpretation of the discourse of migrants, also in practical terms, by intercultural mediators operating in the field of humanitarian aid and support to migrants and asylum seekers.

La conoscenza come ars combinatoria: internet e la questione del ‘filtraggio del sapere’ secondo Umberto Eco
Creators: name: Altamura, Gianpaolo

Subjects: library; knowledge; internet; web

description: According to Umberto Eco, the spread of digital technologies and the Internet is an issue concerning the humanities because it involves the structure of our knowledge. The web is a medium where many writings proliferate chaotically, without a hierarchy and with no respect for authority. The result is an open and rhizomatic space similar to a big library, as Eco puts it. Moreover, according to Eco, the web needs to be filtered because of its exorbitant amount of data which cannot be interpreted: it is like ‘Funes el memorioso’, the title character of Borges’s novel, who had a prodigious memory but was hopelessly stupid.

description: Performance evaluation in multimedia retrieval, as in the information retrieval domain at large, relies heavily on retrieval experiments, employing a broad range of techniques and metrics. These can involve human-in-the-loop and machine-only settings for the retrieval process itself and the subsequent verification of results. Such experiments can be elaborate and use-case-specific, which can make them difficult to compare or replicate. In this paper, we present a formal model to express all relevant aspects of such retrieval experiments, as well as a flexible open-source evaluation infrastructure that implements the model. These contributions intend to make a step towards lowering the hurdles for conducting retrieval experiments and improving their reproducibility.

description: We carefully analyse the present experimental evidence for a complex CKM matrix, even allowing for New Physics contributions to $ε_{K}$, $a_{J/ΨK_S}$, $ΔM_{B_{d}}$, $ΔM_{B_{s}}$, and the $ΔI=1/2$ piece of $B\toρρ$ and $B\toρπ$. We emphasize the crucial r\^ ole played by the angle $γ$ in both providing irrefutable evidence for a complex CKM matrix and placing constraints on the size of NP contributions. It is shown that even if one allows for New Physics a real CKM matrix is excluded at a 99.92% C.L., and the probability for the phase $γ$ to be in the interval $[-170^\circ;-10^\circ]\cup [10^\circ;170^\circ]$ is 99.7%.

Comunicazione politica online: un percorso a due velocità

Subjects: fast thinking; slow thinking; online political communication; confirmation bias; emotional heuristic

description: The development of online political communication has profoundly changed the way we enter into a relationship with political reality. Some features of the Internet allow us to benefit from political communication by using a fast, intuitive, superficial and emotion-based way of thinking. However, we can also rely on another, slower, more reflective, in-depth way of thinking; under appropriate conditions (time available, motivation and competence) we can activate this thinking mode when we use online political communication. Focusing on how citizens use online political communication to acquire political news and relate to politicians, this paper will show that the exclusive use of fast thinking increases the risk of being manipulated and essentially excluded from political involvement. On the contrary, the integration of fast and slow thinking increases the probability of using online political communication in an active, conscious and critical way.

description: Bose metals are metals made of Cooper pairs, which form at very low temperatures in superconducting films and Josephson junction arrays as an intermediate phase between superconductivity and superinsulation. We predicted the existence of this 2D metallic phase of bosons in the mid 90s, showing that they arise due to topological quantum effects. The observation of Bose metals in perfectly regular Josephson junction arrays fully confirms our original prediction and rules out alternative models based on disorder. Here, we review the basic mechanism leading to Bose metals. The key points are that the relevant vortices in granular superconductors are core-less, mobile XY vortices which can tunnel through the system due to quantum phase slips, that there is no charge-phase commutation relation preventing such vortices to be simultaneously out of condensate with charges, and that out-of-condensate charges and vortices are subject to topological mutual statistics interactions, a quantum effect that dominates at low temperatures. These repulsive mutual statistics interactions are sufficient to increase the energy of the Cooper pairs and lift them out of condensate. The result is a topological ground state in which charge conduction along edges and vortex movement across them organize themselves so as to generate the observed metallic saturation at low temperatures. This state is known today as a bosonic topological insulator.

The Effects of Multiple Companions on the Efficiency of the SIM Planet Searches

description: The Space Interferometry Mission (SIM) is expected to make precise astrometric measurements that can be used to detect low mass planets around nearby stars. Since most nearby stars are members of multiple star systems, many stars will have a measurable acceleration due to their companion, which must be included when solving for astrometric parameters and searching for planetary perturbations. Additionally, many of the stars with one radial velocity planet show indications of additional planets. Therefore, astrometric surveys like SIM must be capable of detecting planets and measuring orbital parameters in systems with multiple stellar and/or planetary companions. We have conducted Monte Carlo simulations to investigate how the presence of multiple companions affects the sensitivity of an astrometric survey such as SIM. We find that the detection efficiency for planets in wide binary systems is relatively unaffected by the presence of a binary companion, if the planetary orbital period is less than half the duration of the astrometric survey. For longer orbital periods, there are significant reductions in the sensitivity of an astrometric survey. Additionally, we find that the signal required to detect a planet can be increased significantly due to the presence of an additional planet orbiting the same star. Fortunately, adding a modest number of precision radial velocity observations significantly improves the sensitivity for many multiple planet systems. Thus, the combination of radial velocity observations and astrometric observations by SIM will be a particularly valuable for studying multiple planet systems.

description: The PANS equations model is used to predict the transitional Taylor-Green vortex (TGV) flow at Re=3000. A new form of the closure is proposed, in which the PANS procedure is applied to a variant of the BHR turbulence model. The TGV is a benchmark case for transitional flows in which the onset of turbulence is driven by vortex-stretching and reconnection mechanisms. Since these physical phenomena are observed in numerous flows of variable-density, this study constitutes the first step toward extending the PANS method to such a class of problems. We start by deriving the governing equations of the model and analyze the selection of the parameters controlling its physical resolution, fe and fk, through a-priori testing. Afterward, we conduct PANS computations at different constant physical resolutions to evaluate the model's accuracy and cost predicting the TGV flow. This is performed through simple verification and validation exercises, and the physical and modeling interpretation of the numerical predictions. The results confirm that PANS can efficiently (accuracy vs. cost) predict the present flow problem. Yet, this is closely dependent on the physical resolution of the model. Whereas high-physical resolution (fk<0.50) computations are in good agreement with the reference DNS studies, low-physical resolution (fk>=0.50) simulations lead to large discrepancies with the reference data. The physical and modeling interpretation of the results demonstrates that the origin of these distinct behaviors lies in the model's ability to resolve the phenomena driving the onset of turbulence not amenable to modeling by the closure. The comparison of the computations' cost indicates that high-physical resolution PANS achieves the accuracy of DNS (fk=0.00) at a fraction of the cost. We observe a cost reduction of one order of magnitude at the current Re, which is expected to grow with Re.
Role of the $σ$-resonance in determining the convergence of chiral perturbation theory

description: The dimensionless parameter $ξ= M_π^2/(16 π^2 F_π^2)$, where $F_π$ is the pion decay constant and $M_π$ is the pion mass, is expected to control the convergence of chiral perturbation theory applicable to QCD. Here we demonstrate that a strongly coupled lattice gauge theory model with the same symmetries as two-flavor QCD but with a much lighter $σ$-resonance is different. Our model allows us to study efficiently the convergence of chiral perturbation theory as a function of $ξ$. We first confirm that the leading low energy constants appearing in the chiral Lagrangian are the same when calculated from the $p$-regime and the $ε$-regime as expected. However, $ξ\lesssim 0.002$ is necessary before 1-loop chiral perturbation theory predicts the data within 1%. For $ξ> 0.0035$ the data begin to deviate dramatically from 1-loop chiral perturbation theory predictions. We argue that this qualitative change is due to the presence of a light $σ$-resonance in our model. Our findings may be useful for lattice QCD studies.
