Combination of D0 measurements of the top quark mass
2017
We present a combination of measurements of the top quark mass by the D0 experiment in the lepton+jets and dilepton channels. We use all the data collected in Run I (1992--1996) at $\sqrt s=1.8$ TeV and Run II (2001--2011) at $\sqrt s=1.96$ TeV of the Tevatron $p \bar{p}$ collider, corresponding to integrated luminosities of 0.1 fb$^{-1}$ and 9.7 fb$^{-1}$, respectively. The combined result is: $m_t = 174.95 \pm0.40\,{\rm(stat)} \pm 0.64\,{\rm(syst)}\,{\rm{GeV}}=174.95 \pm 0.75 \, {\rm{GeV}}$.
Probabilistic semantics for categorical syllogisms of Figure II
2018
A coherence-based probability semantics for categorical syllogisms of Figure I, which have transitive structures, has been proposed recently (Gilio, Pfeifer, & Sanfilippo [15]). We extend this work by studying Figure II under coherence. Camestres is an example of a Figure II syllogism: from Every P is M and No S is M infer No S is P. We interpret these sentences by suitable conditional probability assessments. Since the probabilistic inference of \(\bar{P}|S\) from the premise set \(\{M|P,\bar{M}|S\}\) is not informative, we add \(p(S|(S \vee P))>0\) as a probabilistic constraint (i.e., an “existential import assumption”) to obtain probabilistic informativeness. We show how to propagate the…
Triassic/Jurassic boundary in peritidal carbonates from western Tethys
2016
A carbonate platform from the western margin of the Ionian Tethys has been investigated for biotic and geochemical variations across the Triassic/Jurassic boundary (TJB). The section of Mount Sparagio (north-western Sicily) exposes a peritidal succession of Rhaetian-Hettangian age with a thickness of about 400 m. The peritidal sediments are organized in metre-scale shallowing upward cycles formed by subtidal, intertidal and supratidal facies. Along the section, the subtidal facies vary from bioturbated mud/wackestones with rare mollusc shells, to Megalodont-rich wacke/packstones to, more rarely, coral bafflestones, most likely as response to variations of the accommodation space and water e…
Modeling multiple taxis: Tumor invasion with phenotypic heterogeneity, haptotaxis, and unilateral interspecies repellence
2021
We provide a short review of existing models with multiple taxis performed by (at least) one species and consider a new mathematical model for tumor invasion featuring two mutually exclusive cell phenotypes (migrating and proliferating). The migrating cells perform nonlinear diffusion and two types of taxis in response to non-diffusing cues: away from proliferating cells and up the gradient of surrounding tissue. Transitions between the two cell subpopulations are influenced by subcellular (receptor binding) dynamics, thus conferring the setting a multiscale character. We prove global existence of weak solutions to a simplified model version and perform numerical simulations for the full se…
On the pattern recognition and classification of stochastically episodic events
2012
Published version of a chapter published in the book: Transactions on Compuational Collective Intelligence VI. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-29356-6_1 Researchers in the field of Pattern Recognition (PR) have traditionally presumed the availability of a representative set of data drawn from the classes of interest, say ω 1 and ω 2 in a 2-class problem. These samples are typically utilized in the development of the system’s discriminant function. It is, however, widely recognized that there exists a particularly challenging class of PR problems for which a representative set is not available for the second class, which has motivated a great deal of…
Starptautisku lielpasākumu ekonomiskās ietekmes novērtēšana.
2016
Starptautisku liepasākumu norise rada dažāda veida ietekmi vietējā, reģionāla un nacionālā līmenī, tostarp ekonomisko ietekmi, kuras novērtēšanas tradīcija pasaulē izveidota jau pagājušajā gadsimtā, bet Latvijā kļuvusi aktuāla vien pēdējos gados. Darba mērķis ir pētīt un apkopot informāciju par starptautiskiem lielpasākumiem, to radīto ietekmi un ekonomiskās ietekmes novērtēšanas metodēm, kā arī izstrādāt priekšlikumus lielpasākumu novērtēšanā un norisē ieinteresētajām pusēm. Bakalaura darba izstrādes rezultātā tika noskaidroti galvenie ieguvumi un ekonomiskā ietekme, ko rada starptautisku lielpasākumu norise Latvijā, kā arī to novērtēšanas iespējas. Bakalaura darbs sastāv no ievada, 3 noda…
Organizational and Individual Values: Their Main and Combined Effects on Work Attitudes and Perceptions
1999
A survey was conducted using a convenient sample of employees (N = 999) from various industries to examine the main and combined effects of organizational and individual values on organizational commitment, perceived organizational support, and procedural justice. Moderated multiple regression analyses showed that employees' reactions were mainly explained by perceived organizational values and value preferences. In contrast, person-organization value fit and interaction effects were marginal. The implications of these findings are discussed.
Do experiential events create city brand?
2016
Resumen Objetivo: Este artículo analiza hasta qué puntos los megaeventos (grandes eventos) pueden desarrollar marcas-ciudad poderosas reconocidas a nivel mundial, tema poco estudiado hasta la fecha. Metodología: Se ha utilizado el método cuantitativo. En concreto se efectuaron 398 encuestas a residentes en Aguascalientes (México), durante la celebración de un megaevento conocido como Feria Nacional de San Marcos. Resultados: Los resultados de la investigación permiten verificar que (i) respecto a los antecedentes: la actitud de los residentes hacia una marca-ciudad mejora tras las experiencias vividas en megaeventos que ocurren esa ciudad (H1) y (ii) respecto a los efectos: queda corroborad…
Perceived Value in Sporting Events (PVSP): A Further Step for the Strategic Management
2020
The perception of sporting events spectators is a crucial area of research in the sport management field. These studies analyze different variables, the perceived value of which has gained relevance in recent years. By providing superior value to consumers, organizations can achieve a competitive advantage and guarantee their sustainability. However, a limitation found in the literature is that most of the scales used to measure it are one-dimensional or with single items, and do not provide enough information. Therefore, this study aims to analyze the psychometric properties of the Multidimensional Scale of Perceived Value (PVSE) for the evaluation of sporting events. The questionnaire was…
Integrated Bayesian Approaches Shed Light on the Dissemination Routes of the Eurasian Grapevine Germplasm
2021
The domestication and spreading of grapevine as well as the gene flow history had been described in many studies. We used a high-quality 7k SNP dataset of 1,038 Eurasian grape varieties with unique profiles to assess the population genetic diversity, structure, and relatedness, and to infer the most likely migration events. Comparisons of putative scenarios of gene flow throughout Europe from Caucasus helped to fit the more reliable migration routes around the Mediterranean Basin. Approximate Bayesian computation (ABC) approach made possible to provide a response to several questions so far remaining unsolved. Firstly, the assessment of genetic diversity and population structure within a we…
