Szegedy's quantum walk is an algorithm for quantizing a general Markov chain. It has plenty of applications such as many variants of optimizations. In order to check its properties in an error-free environment, it is important to have a classical simulator. However, the current simulation algorithms require a great deal of memory due to the particular formulation of this quantum walk. In this paper we propose a memory-saving algorithm that scales as (N2) with the size N of the graph. We provide additional procedures for simulating Szegedy's quantum walk over mixed states and also the Semiclassical Szegedy walk. With these techniques we have built a classical simulator in Python called SQUWALS. We show that our simulator scales as (N2) in both time and memory resources. This package provides some high-level applications for algorithms based on Szegedy's quantum walk, as for example the quantum PageRank.

This dataset contains the experimental procedures, characterization data, and validation results for the surface functionalization of silica-coated upconversion nanoparticles (UCNPs@SiO₂) used in the publication A scalable approach for tailoring silica shells: from synthesis to stability of upconversion nanoparticles.

Thermometric measurements (ºC) were obtained from 8 Eurasian eagle-owls (Bubo bubo) using a repeated measures design in anesthetized individuals under an ambient temperature of 27 °C. Esophageal and cloacal temperatures were recorded using thermistor probes. In addition, infrared thermography was used to measure temperatures in the eye (entire eye, including medial, central, and lateral zones) and in the entire feet, with the aim of identifying the highest temperature within each region of interest.

Este conjunto de datos recoge las respuestas de 152 estudiantes de educación secundaria (64 en España y 88 en Marruecos) a un cuestionario sobre percepción social de la ciencia y la tecnología, adaptado de los estudios de percepción social de la ciencia de FECYT. El instrumento, administrado en español (con apoyo en árabe para la muestra marroquí) mediante un formulario en línea, recoge datos sociodemográficos, intereses e información autopercibida sobre distintos ámbitos temáticos, hábitos de consumo cultural y mediático, opiniones y actitudes hacia la ciencia y la tecnología, y un test de 31 ítems dicotómicos sobre concepciones científicas básicas (astronomía, biología, física, química y geología). A partir de las respuestas brutas se han construido escalas compuestas de interés, información, conocimiento, opinión y actitudes hacia la ciencia, con sus correspondientes versiones recodificadas en sentido inverso, agrupadas por país. Materiales asociados al conjunto de datos: Encuesta_secundaria_ES.pdf — Instrumento de recogida de datos: cuestionario en español aplicado a la muestra de España. Encuesta_secundaria_AR.pdf — Instrumento de recogida de datos: versión en árabe del cuestionario, aplicada a la muestra de Marruecos. Respuestas_formulario_ES+AR_revisado.csv — Fichero de respuestas brutas del cuestionario (versiones española y árabe combinadas), codificadas numéricamente. variables+conocimiento.csv — Fichero de escalas construidas: interés, información, conocimiento, opinión y actitudes hacia la ciencia, por país.

[Handle URL] --- English version--- This dataset contains the responses of 152 secondary school pupils (64 in Spain and 88 in Morocco) to a questionnaire on the social perception of science and technology, adapted from FECYT’s studies on the social perception of science. The instrument, administered in Spanish (with Arabic support for the Moroccan sample) via an online form, collects sociodemographic data, interests and self-reported information on various subject areas, cultural and media consumption habits, opinions and attitudes towards science and technology, and a test comprising 31 dichotomous items on basic scientific concepts (astronomy, biology, physics, chemistry and geology). Based on the raw responses, composite scales were constructed for interest, information, knowledge, opinion and attitudes towards science, with their corresponding reverse-scored versions, grouped by country.

A hierarchical hybrid coating (HHC) comprising a ceramic oxide layer and two biodegradable polymeric (polycaprolactone, PCL) layers has been developed on Mg3Zn0.4Ca cast alloy in order to provide a controlled degradation rate and functionality by creating a favorable porous surface topography for cell adhesion. The inner, ceramic layer formed by plasma electrolytic oxidation (PEO) has been enriched in bioactive elements (Ca, P, Si). The intermediate PCL layer sealed the defect in the PEO layer and the outer microporous PCL layer loaded with the appropriate active molecule, thus providing drug-eluting capacity. Morphological, chemical, and biological characterizations of the manufactured coatings loaded with ciprofloxacin (CIP) and paracetamol (PAR) have been carried out. In vitro assays with cell lines relevant for cardiovascular implants and bone prosthesis (endothelial cells and premyoblasts) showed that the drug-loaded coating allows for cell proliferation and viability. The study of CIP and PAR cytotoxicity and release rate indicated that the porous PCL layer does not release concentrations detrimental to the cells. However, complete system assays revealed that corrosion behavior and increase of the pH negatively affects cell viability. H2 evolution during corrosion of Mg alloy substrate generates blisters in PCL layer that accelerate the corrosion locally in crevice microenvironment. A detailed mechanism of the system degradation is disclosed. The accelerated degradation of the developed system may present interest for its further adaptation to new cancer therapy strategies.
