Remnants of Anderson localization in prethermalization induced by white noise

2017

We study the non-equilibrium evolution of a one-dimensional quantum Ising chain with spatially disordered, time-dependent, transverse fields characterised by white noise correlation dynamics. We establish pre-thermalization in this model, showing that the quench dynamics of the on-site transverse magnetisation first approaches a metastable state unaffected by noise fluctuations, and then relaxes exponentially fast towards an infinite temperature state as a result of the noise. We also consider energy transport in the model, starting from an inhomogeneous state with two domain walls which separate regions characterised by spins with opposite transverse magnetization. We observe at intermedia…

Superconductivity near a magnetic domain wall

2018

We study the equilibrium properties of a ferromagnetic insulator/superconductor structure near a magnetic domain wall. We show how the domain wall size is affected by the superconductivity in such structures. Moreover, we calculate several physical quantities altered due to the magnetic domain wall, such as the spin current density and local density of states, as well as the resulting tunneling conductance into a structure with a magnetic domain wall.

Motivations, engagement and adoption of e-WOM in restaurants.

2022

Resumen El objetivo del presente trabajo fue estudiar el efecto que tienen las motivaciones para consultar y escribir e-WOM sobre el compromiso con el e-WOM y la influencia de dicho compromiso en la adopción del e-WOM consultado. Para analizar estas relaciones, se realizó una investigación empírica aplicada en el contexto de los restaurantes. El ámbito geográfico fue Ecuador, con una muestra de 461 consumidores. Se utilizó un modelo de ecuaciones estructurales y se validó la cadena de relaciones. Los resultados confirmaron las relaciones entre estas variables; además, se presentaron implicaciones académicas interesantes para profundizar en el estudio sobre el compromiso con el e-WOM, así co…

¿Cómo afecta la innovación en la satisfacción y la lealtad hacia el establecimiento minorista?

2021

Resumen En el presente estudio, se examinó el concepto de innovación en el sector minorista y se definieron sus relaciones con otras variables, como la satisfacción y la lealtad, tradicionalmente vinculadas con el establecimiento minorista. Para lograr los objetivos planteados, se delimitó un modelo teórico sustentado en la literatura, que se contrastó mediante un estudio empírico utilizando un cuestionario estructurado ad hoc aplicado a una muestra de 510 clientes de establecimientos de alimentación. El análisis de los datos se desarrolló mediante la técnica de regresión por mínimos cuadrados parciales. Los resultados permiten proponer un conjunto de recomendaciones para la gestión, fundam…

Speeches About Men and Women in Technical Education: Between Reproduction and Transformation. A Study Located in Two Argentinian Provinces

2020

La formación técnica en Argentina ha sido un ámbito históricamente masculinizado. Ante el incremento de la matrícula femenina y la visibilización y demandas sociales respecto de las desigualdades de género, nos preguntamos, de qué manera las instituciones de ETP favorecen el reconocimiento y la participación con miras a la justicia social. Este trabajo analiza discursos sobre las desigualdades entre varones y mujeres (en interseccionalidad con otras) que circulan en 12 instituciones de educación técnico profesional en dos provincias argentinas (Neuquén y Mendoza), y sobre los dispositivos de acompañamiento a la escolaridad y articulación con el trabajo que allí se construyen. Desplegamos un…

Public spending decisions and the role of municipalities in local development in Argentina: An approach from the municipal autonomy and social and po…

2018

El desarrollo endógeno es un tema prioritario en la agenda municipal, atento el rol de liderazgo que les compete a los gobiernos locales en este proceso. A raíz de distintos procesos de descentralización operados desde el nivel central de gobierno hacia los subnacionales, los municipios se han visto obligados a diseñar estrategias y políticas públicas conjuntas con los distintos actores locales, individuos, organizaciones, políticos y asociaciones de la sociedad civil en general, en la búsqueda de soluciones a las problemáticas que plantea la sociedad hoy. En este trabajo se intentará analizar cómo se inserta el gobierno local, en tanto articulador de los esfuerzos de la comunidad, dentro d…

Parasite–copepod interactions in Svalbard: diversity, host specificity, and seasonal patterns

2022

AbstractCopepods of the genera Calanus and Pseudocalanus are important components of Arctic marine ecosystems. Despite the key roles of these zooplankters, little is known about the organisms they interact with most intimately, their parasites and symbionts. We applied metabarcode sequencing to uncover eukaryotic parasites present within these two copepod genera from three areas around the high Arctic archipelago of Svalbard. Ten distinct parasite groups were observed: four different Apostome ciliates, four different dinoflagellates (Chytriodinium sp., Ellobiopsis sp., Thalassomyces sp., and Hematodinium sp.), a Paradinium sp., and a trematode. Apostome ciliates closely related to Pseudocol…

Hard cap espresso extraction and liquid chromatography determination of bioactive compounds in vegetables and spices

2017

Abstract A new analytical procedure, based on liquid chromatography with diode array and fluorescence detection, has been proposed for the determination of bioactive compounds in vegetables and spices after hard cap espresso extraction. This novel extraction system has been tested for the determination of capsaicin and dihydrocapsaicin from fresh chilli and sweet pepper, piperine from ground pepper, curcumin from turmeric and curry, and myristicin from nutmeg. Extraction efficiency was evaluated by using acetonitrile:water and ethanol:water mixtures. The proposed method allows the extraction of samples with 100 mL of 60% (v/v) ethanol in water. The obtained limits of quantification for the …

On two classes of finite supersoluble groups

2017

ABSTRACTLet ℨ be a complete set of Sylow subgroups of a finite group G, that is, a set composed of a Sylow p-subgroup of G for each p dividing the order of G. A subgroup H of G is called ℨ-S-semipermutable if H permutes with every Sylow p-subgroup of G in ℨ for all p∉π(H); H is said to be ℨ-S-seminormal if it is normalized by every Sylow p-subgroup of G in ℨ for all p∉π(H). The main aim of this paper is to characterize the ℨ-MS-groups, or groups G in which the maximal subgroups of every Sylow subgroup in ℨ are ℨ-S-semipermutable in G and the ℨ-MSN-groups, or groups in which the maximal subgroups of every Sylow subgroup in ℨ are ℨ-S-seminormal in G.
