Design and validation of an augmented book for spatial abilities development in engineering students

[EN] This paper presents an application of augmented reality for improving spatial abilities of engineering students. An augmented book called AR-Dehaes has been designed to provide 3D virtual models that help students to perform visualization tasks to promote the development of their spatial ability during a short remedial course. A validation study with 24 Mechanical Engineering freshmen at La Laguna University (Spain) has concluded that the training had a measurable and positive impact on students' spatial ability. On the other hand, results obtained using a satisfaction questionnaire illustrate that AR-Dehaes is considered an easy to use, attractive, and very useful technique for students. AR-Dehaes has proved to be a very cost-effective tool insofar as it only required an ordinary PC with a webcam to be used.Martín-Gutiérrez, J.; Saorín, J.; Contero, M.; Alcañiz Raya, ML.; Pérez Lopez, DC.; Ortega Pérez, M.

Ahorro energético en riego por aspersión. Pruebas de nuevos aspersores en banco automático con viento

El consumo energético en regadío es directamente proporcional a los valores objetivos de presión de una red colectiva de riego presurizada. El sistema de riego en parcela que más condiciona esta presión objetivo es el riego por aspersión. En este trabajo se ha analizado el comportamiento de los aspersores más utilizados en España en condiciones normales de funcionamiento frente a condiciones de presiones más bajas. Para ello se utilizó un banco de ensayo automático con viento y otro en condiciones confinadas sin viento. Se analizaron los aspersores en múltiples condiciones de trabajo, priorizando en el estudio la variable presión. Para ello se contempló un rango de presiones de 1,5 bar a 3.5 bar y con dos regímenes de viento: sin viento y con viento moderado. Como resultados del estudio se ofrece un análisis global de los datos obtenidos, que justifican la posibilidad de reducir la presión en riego por aspersión Además, se profundiza en resultados concretos para la reducción de la presión en el marco de riego de doce por quince metros

TICdb: a collection of gene-mapped translocation breakpoints in cancer

BACKGROUND: Despite the importance of chromosomal translocations in the initiation and/or progression of cancer, a comprehensive catalog of translocation breakpoints in which these are precisely located on the reference sequence of the human genome is not available at present. DESCRIPTION: We have created a database that describes the genomic location of 1,225 translocation breakpoints in human tumors, corresponding to 247 different genes, using information from publicly available sources. Junction sequences from reciprocal translocations were obtained from 655 different references (either from the literature or from nucleotide databases), and were mapped onto the reference sequence of the human genome using BLAST. All translocation breakpoints were thus referred to precise nucleotide positions (949 breakpoints) or gene fragments (introns or exons, 276 breakpoints) within specific Ensembl transcripts. CONCLUSION: TICdb is a comprehensive collection of finely mapped translocation breakpoints, freely available at . It should facilitate the analysis of sequences encompassing translocation breakpoints and the identification of factors driving translocation events in human tumors

SkyCDS: A resilient content delivery service based on diversified cloud storage

Cloud-based storage is a popular outsourcing solution for organizations to deliver contents to end-users. However, there is a need for contingency plans to ensure service provision when the provider either suffers outages or is going out of business. This paper presents SkyCDS: a resilient content delivery service based on a publish/subscribe overlay over diversified cloud storage. SkyCDS splits the content delivery into metadata and content storage flow layers. The metadata flow layer is based on publish-subscribe patterns for insourcing the metadata control back to content owner. The storage layer is based on dispersal information over multiple cloud locations with which organizations outsource content storage in a controlled manner. In SkyCDS, the content dispersion is performed on the publisher side and the content retrieving process on the end-user side (the subscriber), which reduces the load on the organization side only to metadata management. SkyCDS also lowers the overhead of the content dispersion and retrieving processes by taking advantage of multi-core technology. A new allocation strategy based on cloud storage diversification and failure masking mechanisms minimize side effects of temporary, permanent cloud-based service outages and vendor lock-in. We developed a SkyCDS prototype that was evaluated by using synthetic workloads and a study case with real traces. Publish/subscribe queuing patterns were evaluated by using a simulation tool based on characterized metrics taken from experimental evaluation. The evaluation revealed the feasibility of SkyCDS in terms of performance, reliability and storage space profitability. It also shows a novel way to compare the storage/delivery options through risk assessment. (C) 2015 Elsevier B.V.

Transvaginal ultrasound versus magnetic resonance imaging for preoperative assessment of myometrial infiltration in patients with low-grade endometrioid endometrial cancer: A systematic review and head-to-head meta-analysis

Purpose: We aimed to compare the diagnostic performance of magnetic resonance imaging (MRI) and transvaginal ultrasound (TVS) for detecting myometrial invasion (MI) in patients with low-grade endometrioid endometrial carcinoma. Methods: A comprehensive search of MEDLINE (Pubmed), Web of Science, Embase and Scopus (from January 1990 to December 2022) was performed for articles comparing TVS and MRI in the evaluation of myometrial infiltration in low-grade (grade 1 or 2) endometrioid endometrial carcinoma in the same group of patients. We used QUADAS-2 tool for assessing the risk of bias of studies. Results: We found 104 citations in our extensive research. Four articles were ultimately included in the meta-analysis, after excluding 100 reports. All articles were considered low risk of bias in most of the domains assessed in QUADAS-2. We observed that pooled sensitivity and specificity for detecting deep MI were 65% (95% confidence interval [CI] = 54%-75%) and 85% (95% CI = 79%-89%) for MRI, and 71% (95% CI = 63%-78%) and 76% (95% CI = 67%-83%) for TVS, respectively. No statistical differences were found between both imaging techniques (p > 0.05). We observed low heterogeneity for sensitivity and high for specificity regarding TVS; and moderate for both sensitivity and specificity in case of MRI. Conclusions: The diagnostic performance of TVS and MRI for the evaluation of deep MI in women with low-grade endometrioid endometrial cancer is similar. However, further research is needed as the number of studies is scanty

Spanish shrimp (Pandalus borealis) fishery in Flemish Cap in 1997.

In 1997 one Spanish trawler have been involved in the shrimp fishery in Flemish Cap (NAFO Div. 3M) from March to May. A scientific observer remained on board this trawler during all the fishing period, providing information on the fishing activity and carrying out biological sampling. The gear used was a twin trawl, with a 19 mm bar spacing sorting grate. In this paper, the main results of this fishery are presented
