Thermalization in Kitaev's quantum double models via Tensor Network techniques

We show that the Davies generator associated to any 2D Kitaev's quantum double model has a non-vanishing spectral gap in the thermodynamic limit. This validates rigorously the extended belief that those models are useless as self-correcting quantum memories, even in the non-abelian case. The proof uses recent ideas and results regarding the characterization of the spectral gap for parent Hamiltonians associated to Projected Entangled Pair States in terms of a bulk-boundary correspondence.Comment: 68 page

Las nuevas competencias del profesional de la información: del control de documentos a la gestión del conocimiento

Se presenta una reflexión sobre el cambio que las tecnologías de la información han producido en los profesionales de la información y el conocimiento, sobre las habilidades, conocimientos y aptitudes que se les requieren actualmente, así­ como sobre los proyectos que han pretendido definir estas competencias. En particular, se presentan los resultados de proyectos como el desarrollado por el Consejo de Europa, que aboga por definir nuevos perfiles profesionales par a nuevos puestos de trabajo. También se muestran los documentos elaborados por sociedades profesionales europeas, como ECIA, y norteamericanas, como SLA, que distinguen entre conocimientos y aptitudes, aunque se diferencian en la forma de agrupar los distintos conocimientos necesarios. Por último, se presenta el proyecto KALIPER, promovido por asociaciones educativas norteamericanas sobre biblioteconomí­a y documentación, como ALISE, y la fundación W.K. Kellogg. KALIPER está basado en un cuestionario a facultades del área en Estados Unidos. Entre los resultados, destacan la transición desde estudios más biblioteconómicos a estudios enfocados hacia la documentación y el aumento de las ofertas multidisciplinares, aunque los encuestados consideran que el núcleo de las titulaciones se mantiene estable

Social media in public health: an analysis of national health authorities and leading causes of death in Spanish-speaking Latin American and Caribbean countries

Background: Information and communications technologies, like social media, have the potential to reduce some barriers in disease prevention and control in the Americas. National health authorities can use these technologies to provide access to reliable and quality health information. A study was conducted to analyze availability of information about the leading causes of death on social media channels of national health authorities in 18 Spanish-speaking Latin American and Caribbean countries. Methods: We gathered data of national health authorities's institutional presence in social media. Exploratory-descriptive research was useful for analysis and interpretation of the data collected. An analysis was carried out for 6 months, from April 1 to September 30, 2015. Results: Sixteen of the 18 countries studied have institutional presences on social media. National health authorities have a presence in an average of almost three platforms (2.8%). An average of 1% of the populations with Internet access across the 18 countries in this study follows national health authorities on social media (approximately, an average of 0. 3% of the total population of the countries under study). On average, information on 3.2 of the 10 leading causes of death was posted on the national health authorities' Facebook pages, and information on 2.9 of the 10 leading causes of death was posted on their Twitter profiles. Additionally, regarding public health expenditures and the possibility of retrieving information on the leading causes of death, an apparent negative correlation exists in the case of Facebook, r(13) = -.54, P = .03 and a weak negative correlation in the case of Twitter, r(14) = -.26, P = .31, for the countries with presences in those networks

Phytogenic feed additives in poultry : achievements, prospective and challenges

Phytogenic feed additives have been largely tested in poultry production with the aim to identify their effects on the gastrointestinal function and health, and their implications on the birds' systemic health and welfare, the production efficiency of flocks, food safety, and environmental impact. These feed additives originating from plants, and consisting of herbs, spices, fruit, and other plant parts, include many different bioactive ingredients. Reviewing published documents about the supplementation of phytogenic feed additives reveals contradictory results regarding their effectiveness in poultry production. This indicates that more effort is still needed to determine the appropriate inclusion levels and fully elucidate their mode of actions. In this frame, this review aimed to sum up the current trends in the use of phytogenic feed additives in poultry with a special focus on their interaction with gut ecosystem, gut function, in vivo oxidative status and immune system as well as other feed additives, especially organic acids

Study on the use of metadata for digital learning objects in university institutional repositories (MODERI)

Metadata is a core issue for the creation of repositories. Different institutional repositories have chosen and use different metadata models, elements and values for describing the range of digital objects they store. Thus, this paper analyzes the current use of metadata describing those Learning Objects that some open higher educational institutions' repositories include in their collections. The goal of this work is to identify and analyze the different metadata models being used to describe educational features of those specific digital educational objects (such as audience, type of educational object, learning objectives, etc.). Also discussed is the concept and typology of Learning Objects (LO) through their use in University Repositories. We will also examine the usefulness of specifically describing those learning objects, setting them apart from other kind of documents included in the repository, mainly scholarly publications and research results of the Higher Education institution.En prens

The Vision of the Main Mobile Apps Related to Caravanning: an Analysis of the Reviews Focusing on Users and Developers

Mobile applications (apps) are becoming an essential tool when it comes to sightseeing. There is even a specific category for trips in the leading app stores. These are no strangers to the rise of the itinerant travel style, the caravans. The study aims to understand the situation of the main caravanning apps in Spain. We have carried out a web scraping methodology using a sample of 1,601 Spanish reviews of the main apps related to caravanning. The most interesting findings, among others, are that we are getting to know a sector that up to now was unknown and that even has not been affected by the pandemic crisis. Besides, the paper has demonstrated that developers do not follow the right strategies in caravanning apps. The paper also shows users' most crucial concerns about these apps. Therefore, managers of caravanning apps could improve their strategies by focusing their attention on users' concerns and, most important, reviews to respondThis publication has been possible thanks to the support of Spain's Ministry of Universities which has granted David Perea with a Margarita Salas grant for the training of young PhD included in the grants for the requalification of the Spanish University System 2021-2023, financed by the European Union Next Generation E

Maternal learning and Creep-Feeding: two strategies determining the post-weaning performance of piglets

The early exposure of foetus to certain volatiles may result in a further preference for these compounds later in life and can positively affect the further acceptance of food containing a similar flavour. The study consisted in three trials: 1) determination of the effects on piglet performance of flavour supplementation in sow’s diets (late gestation and lactation) and in weaning diets; 2) creep-feed consumption and preference evaluation by a double choice test (DCHT) comparing the studied flavour and a negative control; 3) identification of the independent role of flavour inclusion in late gestation or lactation throughout DCHT. The inclusion of flavour in sow’s diets improved piglets’ appetite when same flavour was included at weaning. The positive reward associated to the flavour included in sow’s diet was stronger when piglets were offered a non-flavoured creep-feed. Exposure to flavour only at the end of gestation would be enough to condition the piglets
