Electrical conductivity of a pion gas

Repositorio: Docta Complutense
Fernández Fraile, Daniel, Gómez Nicola, Ángel|||0000-0002-2708-9303

The electrical conductivity of a pion gas at low temperatures is studied in the framework of linear response and chiral perturbation theory. The standard ChPT power counting has to be modified to include pion propagator lines with a nonzero thermal width in order to properly account for collision effects typical of kinetic theory. With this modification, we discuss the relevant chiral power counting to be used in the calculation of transport coefficients. The leading order contribution is found...

Almost holomorphic embeddings in Grassmannians with applications to singular symplectic submanifolds

Repositorio: Docta Complutense
Muñoz, Vicente, Presas, Francisco, Sols, Ignacio

In this paper we use Donaldson's approximately holomorphic techniques to build embeddings of a closed symplectic manifold with symplectic form of integer class in the Grassmannians Gr(r, N). We assure that these embeddings are asymptotically holomorphic in a precise sense. We study first the particular case of CPN obtaining control on N and we improve in a sense a classical result about symplectic embeddings. The main reason of our Study is the construction of singular determinantal...

φ →π⁺π⁻ decay within a chiral unitary approach

Repositorio: Docta Complutense
Oller, J. A., Oset, E., Peláez Sagredo, José Ramón|||0000-0003-0737-4681

Starting from the chiral perturbation theory Lagrangian, but keeping different masses for the charged and neutral mesons (m_u ≠ m_d), and using a previously developed nonperturbative unitary scheme that generates the lightest meson-meson resonances, we construct KK̅→KK̅ and KK̅→π⁺π⁻ in the vector channel. This allows us to obtain the kaon-loop contribution to φ-ρ mixing and study the φ→π⁺π⁻ decay. The dominant contribution to this decay comes from the φ→ϒ→π⁺π⁻ process. However, there can be...

Manzanero Puebla, Antonio Lucas|||0000-0003-2619-4571, Palomo Seldas, Rubén

Se ha debatido largamente sobre la realidad de las memorias disociativas. Desde perspectivas clínicas se ha apoyado la existencia de este fenómeno que se ha intentado extrapolar a contextos legales. Sin embargo, existe poca evidencia para poder confirmarlo, al tiempo que las memorias disociativas o reprimidas irían en contra del funcionamiento normal de la memoria. La confusión entre psicología clínica y psicología forense, una inadecuada definición de amnesia, la carencia de un completo...

Cloudy bag model: convergent perturbation expansion for the nucleon

Repositorio: Docta Complutense
Dood, L. R., Thomas, A. W., Fernández Álvarez-Estrada, Ramón|||0000-0003-0884-1157

A previously published bound on the probability of finding n pions in the dressed nucleon in Chew-Low theory is improved. The proof is then extended to the recently derived cloudy-bag-model Hamiltonian. Together with a bound on the average number of pions (0.9±1.0), our result strongly suggests a rapid convergence of the perturbation expansion in the cloudy bag model.

Regulation of cardiac ion channels by transcription factors: Looking for new opportunities of druggable targets for the treatment of arrhythmias

Repositorio: Docta Complutense
Crespo García, Teresa, Cámara Checa, Anabel, Dago Requena, María, Rubio Alarcón, M., Rapún Jiménez, Josu, Tamargo Menéndez, Juán, Delpón Mosquera, Eva, Caballero, Rafael

Cardiac electrical activity is governed by different ion channels that generate action potentials. Acquired or inherited abnormalities in the expression and/or function of ion channels usually result in electrophysiological changes that can cause cardiac arrhythmias. Transcription factors (TFs) control gene transcription by binding to specific DNA sequences adjacent to target genes. Linkage analysis, candidate-gene screening within families, and genome-wide association studies have linked rare...

Rozas, David, Gilbert, Nigel, Hodkinson, Paul, Hassan, Samer

Peer production communities are based on the collaboration of communities of people, mediated by the Internet, typically to create digital commons, as in Wikipedia or free software. The contribution activities around the creation of such commons (e.g., source code, articles, or documentation) have been widely explored. However, other types of contribution whose focus is directed toward the community have remained significantly less visible (e.g., the organization of events or mentoring). This...

Virgili Rodón, Carmina

The record of geological time in stratigraphic successions is discontinuous because periods of norrdeposition are much longer than those of active sedimentation Weathering takes place during these breaks, deeply disturbing the sinsedimentary fabncs. These phenomena are mainly of pedogenetic origin, but also due to ground waters. The final result is a «continentalization» of the series, being that the cause of several erroneous interpretations of ancient sediments. The study of paleoweatherings...

El valor de la fotografía como objeto encontrado/apropiado/modificado y como práctica experimental resultan indiscutibles en la obra de Luis Gordillo (Sevilla, 1934). Pese a no tener referencias fotográficas y declarar que el Pop art fue su punto de conexión con el poder de la imagen, el contexto experimental y transgresor de los años setenta resultaría definitivo para convencerle del poder de la fotografía como objeto y lenguaje. Sea como fuere, empatizaría con el ideario experimental de la...

On the time-varying nature of the debt-growth nexus: evidence from the euro area

Repositorio: Docta Complutense
Gómez-Puig, Marta, Sosvilla-Rivero, Simón

This article uses the DCC-generalized autoregressive conditional heteroskedasticity model to investigate the existence of time-varying correlations between public debt and economic growth. To that end, we use annual data from both central and peripheral countries of the euro area for the period 1961–2015. The results suggest that the relationships between these variables are time-varying and that in some countries and for some periods, there is a positive association between them.

Invertebrate Palaeontology and Sequence Stratigraphy: complementary methods and evidence to explain the geological record

Repositorio: Docta Complutense
Fernández López, Sixto Rafael|||0000-0002-4492-2985, Sha, Jingeng

The fossil record and the stratigraphic record are two components of the geological record different in nature, and they can be separately interpreted and tested in many cases of Invertebrate Palaeontology. Abundance, diversity and stratigraphic persistence are outstanding features of the fossil invertebrates. Therefore, the complementarity (as the capacity of two contrasted theories together to explain a body of phenomena, although each separately accounts for only some aspects) or the...

The influences of public law on private law and the correlations of the corporate social responsibility vs. the human rights

Repositorio: Docta Complutense
Da Silva Veiga, Fabio

Historically, the debate about the existing confrontation between Public and Private Law dates back to the middle twentieth century, primarily to the decision of the Federal Constitutional Court of Germany (FCCG) on the Lüth case of 1958. Since then, the discussion has been gaining some space, even being considered the “full Constitutionalization of Law” (Vergrundrechtlichung des gesamten Rechts), on one hand, and celebrated as the full accomplishment of the fundamental rights (Alexy, 2009)[1...

Signal representation on the angular Poincare sphere, based on second-order moments

Repositorio: Docta Complutense
Bastiaans, Martin J., Alieva, Tatiana Krasheninnikova

Based on the analysis of second-order moments, a generalized canonical representation of a two-dimensional optical signal is proposed, which is associated with the angular Poincare sphere. Vortex-free ( or zero-twist) optical beams arise on the equator of this sphere, while beams with a maximum vorticity ( or maximum twist) are located at the poles. An easy way is shown how the latitude on the sphere, which is a measure for the degree of vorticity, can be derived from the second-order moments....

A Decision Rule to Minimize Daily Capital Charges in Forecasting Value-at-Risk

Repositorio: Docta Complutense
McAleer, Michael, Jiménez-Martín, Juan-Ángel, Pérez-Amaral, Teodosio

Under the Basel II Accord, banks and other Authorized Deposit-taking Institutions (ADIs) have to communicate their daily risk estimates to the monetary authorities at the beginning of the trading day, using a variety of Value-at-Risk (VaR) models to measure risk. Sometimes the risk estimates communicated using these models are too high, thereby leading to large capital requirements and high capital costs. At other times, the risk estimates are too low, leading to excessive violations, so that...



The heat flow during the formation of ribbon terrains on Venus

Repositorio: Docta Complutense
Ruiz Pérez, Javier|||0000-0002-3937-8380

Ribbons are regularly spaced, between 2 and 6 km, troughs that exist on venusian tesserae, which are mainly located in, and characterize to, venusian crustal plateaus. Independent of the geological or temporal relations with other features, regularly and similarly spaced ribbons on several tesserae strongly suggest a thermal control on the thickness of the deformed layer. This can be used to constraint the heat flow at the time of ribbon formation, which holds important implications for the...

Location of crossings in the Floquet spectrum of a driven two-level system

Repositorio: Docta Complutense
Creffield, Charles E.

The calculation of the Floquet quasi-energies of a system driven by a time-periodic field is an efficient way to understand its dynamics. In particular, the phenomenon of dynamical localization can be related to the presence of close approaches between quasienergies (either crossings or avoided crossings). Here we consider a driven two-level system and study how the locations of crossings in the quasienergy spectrum alter as the field parameters are changed. A perturbational scheme provides a...

Gómez, César, Hernández Redondo, Rafael|||0000-0002-1558-1309

The planar dilatation operator of N = 4 supersymmetric Yang-Mills is the hamiltonian of an integrable spin chain whose length is allowed to fluctuate. We will identify the dynamics of length fluctuations of planar N = 4 Yang-Mills with the existence of an abelian Hopf algebra Z symmetry with non-trivial co-multiplication and antipode. The intertwiner conditions for this Hopf algebra will restrict the allowed magnon irreps to those leading to the magnon dispersion relation. We will discuss...

Repositorio: Docta Complutense
González de Vallejo, Luis I., Capote del Villar, Ramón, Cabrera Pérez, Luis, Insúa Arévalo, Juan Miguel, Acosta Yepes, Juan

A series of clastic dikes and tubular vents were identified in southern Tenerife (Canary Islands). These features are the result of seismic liquefaction of a Holocene sand deposit, as the consequence of a high intensity paleoearthquake. The peak ground acceleration (pga) and magnitude of the paleoearthquake generating these liquefaction features were estimated by back calculation analysis. A representative value of 0.30 ± 0.05 g was obtained for the pga. From this, an earthquake intensity of IX...

Brauer, Uwe, Karp, Lavi

We show global existence of classical solutions for the nonlinear Nordström theory with a source term and a cosmological constant under the assumption that the source term is small in an appropriate norm, while in some cases no smallness assumption on the initial data is required. In this theory, the gravitational field is described by a single scalar function that satisfies a certain semi-linear wave equation. We consider spatial periodic deviation from the background metric, that is why we...

Se mantuvo la pequeña producción basada en la caña, pero los grandes inversores apostaron por el desarrollo del cultivo de la remolacha y por la industria azucarera basada en esa materia prima. Un sector importante de los fabricantes españoles se agrupó en 1903 en la Sociedad General Azucarera (SGA), que se especializó fundamentalmente en la fabricación de azúcar de remolacha...

We present a study of the deformation pattern in El Hierro Island through the analysis of GNSS data from surveys carried out between 2015 and 2019 as well as continuous data. The last eruption in El Hierro occurred under the sea on the south rift, lasted from October 2011 to March 2012, and it was preceded by intense seismic activity and nearly 5 cm ground inflation. After this eruptive cycle, further magmatic intrusions were detected, from June 2012 to March 2014, associated to intense seismic...
