Reactome diagram viewer: data structures and strategies to boost performance

2017

Abstract Motivation Reactome is a free, open-source, open-data, curated and peer-reviewed knowledgebase of biomolecular pathways. For web-based pathway visualization, Reactome uses a custom pathway diagram viewer that has been evolved over the past years. Here, we present comprehensive enhancements in usability and performance based on extensive usability testing sessions and technology developments, aiming to optimize the viewer towards the needs of the community. Results The pathway diagram viewer version 3 achieves consistently better performance, loading and rendering of 97% of the diagrams in Reactome in less than 1 s. Combining the multi-layer html5 canvas strategy with a space partit…

Pervasive Displays Research: What's Next?

2019

Reports on the 7th ACM International Symposium on Pervasive Displays that took place from June 6-8 in Munich, Germany.

Study protocol for an online questionnaire survey on symptoms/signs, protective measures, level of awareness and perception regarding covid-19 outbre…

2020

The Centres for Disease Control and Prevention and the World Health Organization have developed preparedness and prevention checklists for healthcare professionals regarding the containment of COVID-19. The aim of the present protocol is to evaluate the impact of the COVID-19 outbreak among dentists in different countries where various prevalence of the epidemic has been reported. Several research groups around the world were contacted by the central management team. The online anonymous survey will be conducted on a convenience sample of dentists working both in national health systems and in private or public clinics. In each country/area, a high (~5–20%) proportion of dentists working th…

Creación de página Web para promover aprendizaje colaborativo en alumnos de máster

2018

[EN] A Web page has been designed by master students in order to engage them in collaborative and cooperative learning, thus improving their learning and comprehension of relevant concepts and topics. To that purpose, topics included in the subject Advanced Techniques in Chemistry which is part of the Master in Sustainable Chemistry of the University of Valencia have been included in the Webpage with the help of WIX software. This approach makes intensive use of the Web as a key technological resource for learning, where the information seen in the subject is summarized and given in an applicative and pertinent context that is easy to understand for all public interested in the topics discu…

Tieteelliset laskentasovellukset ja pilvipalvelut – erityistarkastelussa AWS

2014

Perinteisesti IT-resurssien hankinta on tapahtunut hankkimalla laitteistoa ja ohjelmistoja omaan tai organisaation omistukseen. Näiden resurssien käyttö on yleensä tarkoittanut merkittäviä investointeja laitteistoihin, ohjelmistoihin ja näiden ylläpitoon. Suuressa organisaatiossa kalliiden IT-resurssien käyttöönotto voi olla joissain tapauksissa hyvinkin byrokraattinen prosessi. Tieteellinen laskenta edellyttää usein erittäin suurta laskenta- ja tallennuskapasiteettia. Tutkijat hyötyisivät raskaaseen laskentaan vaadittavien IT-resurssien hankkimisesta palveluna, jolloin usein niukat resurssit voitaisiin keskittää vaadittavan laitteiston hankkimisen ja ylläpidon sijaan ydinongelman tutkimise…

The Adaptation of a Web Information System: A Perspective of Organizations

2011

We provide a different view on the problem of Web Information System (WIS) adaptation, looking from perspective of organizations that are interested in an adapted Web Information System for their needs if a unified system to support similar business processes is used. We propose an adaptation architecture for WIS. Two levels of adaptation are introduced—coarse grained adaptation for the organization level and fine grained adaptation for the user level. The architecture supports also the situation, when users can work with many instances of the system adapted for different organizations, which are integrated into one instance for a particular user.

Resistance of seagrass habitats to ocean acidification via altered interactions in a tri-trophic chain

2020

Despite the wide knowledge about prevalent effects of ocean acidification on single species, the consequences on species interactions that may promote or prevent habitat shifts are still poorly understood. Using natural CO2 vents, we investigated changes in a key tri-trophic chain embedded within all its natural complexity in seagrass systems. We found that seagrass habitats remain stable at vents despite the changes in their tri-trophic components. Under high pCO2, the feeding of a key herbivore (sea urchin) on a less palatable seagrass and its associated epiphytes decreased, whereas the feeding on higher-palatable green algae increased. We also observed a doubled density of a predatory wr…

Lake restoration influences nutritional quality of algae and consequently Daphnia biomass

2020

AbstractFood quality is one of the key factors influencing zooplankton population dynamics. Eutrophication drives phytoplankton communities toward the dominance of cyanobacteria, which means a decrease in the availability of sterols and long-chain polyunsaturated fatty acids (EPA and DHA). The effects of different restoration measures on the nutritional quality of the phytoplankton community and subsequent impacts on zooplankton biomass have rarely been considered. We analyzed the nutritional quality of phytoplankton in the eutrophic Lake Vesijärvi in southern Finland over a 37-year period, and studied the impacts of two restoration measures, biomanipulation and hypolimnetic aeration, on th…

Relationship between cladoceran (Crustacea) functional diversity and lake trophic gradients

2017

Functional diversity (FD) as a biodiversity measure has an explicit role in ecosystem functioning because the effects of environmental changes in ecosystems are determined by biological functions, such as feeding type and trophic position, of particular species. We evaluated the usability of functional characterization and FD of an aquatic keystone group (Crustacea: Cladocera) for enhancing the understanding of long-term lake functional responses to environmental changes. The aims were to separate ecologically significant functional groups, investigate succession of such functional groups during nutrient enrichment process and determine the relationship between FD and lake productivity usin…
