LOD.CS.UNIPA Project: an experience of LOD at the University of Palermo
2012
This paper describes the LOD.CS.UNI.PA Project and its main goal, the transformation process of data already available on the web site of the Computer Science curricula web site at the University of Palermo into data ready to be connected to the LOD. Since 1997 information about bachelor and master degrees in Computer Science at the University of Palermo has been published on the web, and provides a reference point for students, teachers and researchers who have easy access to the information they require. However, the users of the web are now changing; data cannot be published only for human comprehension but intelligent devices also need access to web data and above all they need to under…
gNOMO: a multi-omics pipeline for integrated host and microbiome analysis of non-model organisms
2020
The study of bacterial symbioses has grown exponentially in the recent past. However, existing bioinformatic workflows of microbiome data analysis do commonly not integrate multiple meta-omics levels and are mainly geared toward human microbiomes. Microbiota are better understood when analyzed in their biological context; that is together with their host or environment. Nevertheless, this is a limitation when studying non-model organisms mainly due to the lack of well-annotated sequence references. Here, we present gNOMO, a bioinformatic pipeline that is specifically designed to process and analyze non-model organism samples of up to three meta-omics levels: metagenomics, metatranscriptomic…
A Digital Twin for Lift Planning With Offshore Heave Compensated Cranes
2020
Abstract This paper presents a state-of-the-art digital twin of a hydraulic actuated winch that is used for heave compensation in offshore applications. The digital twin is used as part of a larger simulation model that involves all necessary components to perform lift planning and, subsequently, determine the corresponding weather window. The winch simulation model is described and verified by means of full-scale measurements. In addition, a set of acceptance criteria are presented that should be used whenever verifying digital twins of heave compensating winches that are to be used for lift planning.
Políticas de acceso abierto a la ciencia en las universidades españolas
2013
El objetivo del artículo es analizar el estado de la cuestión de las políticas en favor del acceso abierto (OA) a la ciencia en las universidades españolas. Para ello se han establecido cinco grandes mecanismos de intervención (la creación de infraestructuras y prestación de servicios, la comunicación y difusión, la incentivación económica, la coordinación institucional así como la reglamentación u obligación) que permiten llevar a cabo políticas a favor del acceso abierto y que hemos utilizado para el análisis y la valoración de la situación. La recogida de datos se ha basado en un cuestionario enviado a los vice-rectores de investigación y se ha complementado con la consulta de directorio…
Producción y difusión digitales de las humanidades no vanguardistas en el siglo XX: el ejemplo de la filología catalana medieval
2014
Aquest article ofereix un panorama històric dels formats digitals emprats al segle XX en un petit camp de les Humanitats: la filologia catalana medieval, com a exemple de moltes altres àrees de recerca similars, no avantguardistes, i centrades en estudis textuals. S'hi mostra que la gestió textual i de vocabulari, així com les bades de dades lèxiques i bibliogràfiques, van constituir els seus primers projectes. L'article conclou amb una brevíssima valoració dels desafiaments digitals en el futur immediat, especialment en eines de publicació: pdf front a epub, i l'accelerat procés de compartir la recerca més recent a través de les xarxes socials d'investigadors. S'hi defén la via de la cultu…
Nuevas vías de depósito, nuevos proyectos: consolidación del repositorio institucional RODERIC
2017
El objetivo de este artículo es dar a conocer los nuevos proyectos del repositorio institucional de la Universitat de València, RODERIC, así como las nuevas vías de depósito de documentos de investigación. Para ello, se analizan las distintas actuaciones dentro del apartado de investigación del repositorio. En primer lugar, las centradas en el área de revistas editadas en la UV, los proyectos sobre digitalización de tesis retrospectivas y publicación de tesis corrientes, y finalmente la integración del sistema CRIS con el repositorio. Se acaba con la descripción de una serie de mejoras que se prevén están disponibles en la segunda mitad de 2013. The aim of this paper is to present new proje…
MDP-Based Resource Allocation Scheme Towards a Vehicular Fog Computing with Energy Constraints
2018
As mobile applications deliver increasingly complex functionalities, the demands for even more intensive computation would quickly transcend energy capability of mobile devices. On one hand and in an attempt to address such issues, fog computing paradigm is introduced to mitigate the limited energy and computation resources available within constrained mobile devices, by moving computation resources closer to their users at the edge of the access network. On another hand, most of electric vehicles (EVs), with increasing computation, storage and energy capabilities, spend more than 90% of time on parking lots. In this paper, we conceive the basic idea of using the underutilized computation r…
The N-terminal domain of the light-harvesting chlorophyll a/b-binding protein complex (LHCII) is essential for its acclimative proteolysis.
2000
AbstractVariations in the amount of the light-harvesting chlorophyll a/b-binding protein complex (LHCII) is essential for regulation of the uptake of light into photosystem II. An endogenous proteolytic system was found to be involved in the degradation of LHCII in response to elevated light intensities and the proteolysis was shown to be under tight regulation [Yang, D.-H. et al. (1998) Plant Physiol. 118, 827–834]. In this study, the substrate specificity and recognition site towards the protease were examined using reconstituted wild-type and mutant recombinant LHCII. The results show that the LHCII apoprotein and the monomeric form of the holoprotein are targeted for proteolysis while t…
Scientific Merits and Analytical Challenges of Tree‐Ring Densitometry
2019
X-ray microdensitometry on annually resolved tree-ring samples has gained an exceptional position in last-millennium paleoclimatology through the maximum latewood density (MXD) parameter, but also increasingly through other density parameters. For 50 years, X-ray based measurement techniques have been the de facto standard. However, studies report offsets in the mean levels for MXD measurements derived from different laboratories, indicating challenges of accuracy and precision. Moreover, reflected visible light-based techniques are becoming increasingly popular, and wood anatomical techniques are emerging as a potentially powerful pathway to extract density information at the highest resol…
Information content of data and variables and types of weighting in least-squares regression methods
1990
Abstract Algorithms are given for evaluating the relative amount of useful information related to a particular parameter which is carried by individual data points and intervals of the variables. The algorithms provide an efficient means of using the information contained in a set of data. Applications to the optimization of weighting in regression methods are described. Several informational and combined informational-statistical types of weighting are studied as a means of improving the accuracy and precision of the parameters obtained by non-linear regression.
