توضیحات خلاصه (Summary):

[Abstract] Efficient processing of aggregated range queries on two-dimensional grids is a common requirement in information retrieval and data mining systems, for example in Geographic Information Systems and OLAP cubes. We introduce a technique to represent grids supporting aggregated range queries that requires little space when the data points in the grid are clustered, which is common in practice. We show how this general technique can be used to support two important types of aggregated queries, which are ranked range queries and counting range queries. Our experimental evaluation shows that this technique can speed up aggregated queries up to more than an order of magnitude, with a small space overhead.  Read more…

توضیحات خلاصه (Summary):

[Resumen] Se aborda el camino hacia la desaparición de los periódicos en soporte papel debido a la importante transformación del sector en los últimos anos como consecuencia, entre otros factores, del desarrollo de las tecnologías de la información y la comunicación y al cambio de hábitos de los consumidores de prensa. Mediante el empleo de modelos econométricos, tanto de regresiones cuadráticas como de análisis de relaciones de estabilidad a largo plazo entre variables, se trata de aproximar el ano en que la difusión de los diarios en papel será próxima a cero; lo mismo se plantea con la inversión publicitaria en el sector de la prensa impresa por ser una de sus principales fuentes de ingresos. Los resultados obtenidos no auguran un futuro muy esperanzador en el sector analizado, pues para las cabeceras tomadas como referencia y representación del sector, como son El país, El mundo, La razón y ABC la conclusión es que en 2020 entrarán en un estado crítico al situarse ahí el punto de ruptura de la difusión en papel.[Abstract] We discuss the disappearance of printed newspapers, an important transformation which is a result of, among other factors, the development of information and communication technologies, and the change of press consumers’ habits. By means of econometric models of quadratic regressions and co-integration models we try to approximate the year in which the diffusion of printed newspapers will be near to zero; next, we pose the same problem with regard to advertisement spending in the sector of the printed press because it is one of the main sources of revenue for newspapers. The results obtained do not predict a hopeful future in this sector; for the representative Spanish newspapers, El país, El mundo, La razón, and ABC, the conclusion is that they will have a negligible diffusion in printed formatbefore the year 2020.  Read more…

Advertising investment       Galbraith’s hypothesis       Macroeconomic effects       View all subjects      

توضیحات خلاصه (Summary):

[Resumo]: A recessão que a maioria das economias mundiais suportaram nos últimos anos causou um grande interesse no estudo dos seus efeitos macroeconômicos. Neste contexto, ressurgiu o debate sobre os efeitos do investimento em publicidade, tanto pela sua capacidade potencial para estimular o gasto do consumidor, quanto pelo impacto positivo na recuperação económica. Esta ideia, sustentada na conhecida hipótese de Galbraith, constitui a base deste artigo, cujo objetivo fundamental é testar a citada hipótese por meio de uma análise empírica. Neste estudo, centramo-nos no caso da Espanha usando os dados correspondentes ao período compreendido entre os anos 1976 e 2010. Realizou-se uma análise de cointegração usando duas aproximações (Teste de Engle-Granger e teste de Gregory-Hansen respetivamente), para determinar se existe alguma relação entre investimento de publicidade e seis macro variáveis (PIB, Rendimento Nacional, Procura Interna, Consumo, Poupança e Formação de Capital Fixo), assim como a taxa de desemprego registado. Com os resultados obtidos concluímos que a hipótese de Galbraith não se cumpre no caso da Espanha.[Abstract]: The recession that most of the world economies have been facing in the last years has caused a great interest in the study of its macroeconomic effects. In this context, a debate has resurged regarding the advertising investment, as for its potential capacity to impel the consumer spending and to impact positively on the economic recovery. This idea, sustained in the so-called Galbraith’s hypothesis, constitutes the core of this paper, where the main objective is to test that hypothesis by means of an empirical analysis. In this study, we focus on the Spanish case and the data correspond to the period 1976 -2010. A cointegration analysis is carried out, using two different approaches (Engle-Granger test and Gregory-Hansen test, respectively), to determine if there is any relationship between the advertising investment and six macromagnitudes (GDP, National Income, Consumption, Savings and Fixed Capital Formation), as well as the registered unemployment rate. Based on the results obtained, we conclude that Galbraith’s hypothesis is not fulfilled for the Spanish case.  Read more…

توضیحات خلاصه (Summary):

[Abstract] Context. The recently identified myokine irisin conveys some of the benefits of exercise. Hypopituitarism with adult growth hormone deficiency (HP) is a situation characterized by decreased GH secretion and an altered body composition. Objective. Our aim was to study the skeletal muscle hormone irisin in HP, and compare the results with a similar group of normal subjects. Participants and Methods. Seventeen HP patients and fifty-one normal subjects of similar age and sex were studied. The diagnosis of GH deficiency was confirmed by the presence of pituitary disease and a peak GH secretion below 3 μg/L after an insulin tolerance test. The patients were adequately treated for all pituitary hormone deficits, except for GH. Fasting serum irisin was measured with an enzyme immunoassay, and HOMA-IR, QUICKI and HOMA-β were calculated. Results. Fasting irisin levels (ng/ml) were similar in normal [208.42 (168.44–249.23)] and HP patients [195.13 (178.44–241.44)]. In the control group there were moderate significant positive correlations between irisin and BMI, waist circumference, leptin, fasting insulin, HOMA-IR, HOMA-β, triglycerides, and cholesterol. In the control group there were moderate significant negative correlations between irisin and IGF-I and QUICKI. In the hypopituitary group there were moderate significant positive correlations between irisin and body fat and HOMA-β. Conclusions. We found similar irisin levels in GH deficiency hypopituitary patients when compared with normal subjects. The correlation between irisin and adiposity related factors suggests that that in the case of this clinical model, irisin is regulated by adiposity and not by GH.  Read more…

توضیحات خلاصه (Summary):

[Abstract] Introduction. Nuclear accumulation of a mutant form of the nuclear protein Lamin-A, called Progerin (PG) or Lamin AΔ50, occurs in Hutchinson-Gilford Progeria Syndrome (HGPS) or Progeria, an accelerated aging disease. One of the main symptoms of this genetic disorder is a loss of sub-cutaneous fat due to a dramatic lipodystrophy. Methods. We stably induced the expression of human PG and GFP -Green Fluorescent Protein- as control in 3T3L1 cells using a lentiviral system to study the effect of PG expression in the differentiation capacity of this cell line, one of the most used adipogenic models. Quantitative proteomics (iTRAQ) was done to study the effect of the PG accumulation. Several of the modulated proteins were validated by immunoblotting and real-time PCR. Mitochondrial function was analyzed by measurement of a) the mitochondrial basal activity, b) the superoxide anion production and c) the individual efficiency of the different complex of the respiratory chain. Results. We found that over-expression PG by lentiviral gene delivery leads to a decrease in the proliferation rate and to defects in adipogenic capacity when compared to the control. Quantitative proteomics analysis showed 181 proteins significantly (p < 0.05) modulated in PG-expressing preadipocytes. Mitochondrial function is impaired in PG-expressing cells. Specifically, we have detected an increase in the activity of the complex I and an overproduction of Superoxide anion. Incubation with Reactive Oxygen Species (ROS) scavenger agents drives to a decrease in autophagic proteolysis as revealed by LC3-II/LC3-I ratio. Conclusion. PG expression in 3T3L1 cells promotes changes in several Biological Processes, including structure of cytoskeleton, lipid metabolism, calcium regulation, translation, protein folding and energy generation by the mitochondria. Our data strengthen the contribution of ROS accumulation to the premature aging phenotype and establish a link between mitochondrial dysfuncti  Read more…

Breast tissue classification       Weighted voting tree classifier       Texture analysis       View all subjects      

توضیحات خلاصه (Summary):

[Abstract] This paper describes a novel weighted voting tree classification scheme for breast density classification. Breast parenchymal density is an important risk factor in breast cancer. Moreover, it is known that mammogram interpretation is more difficult when dense tissue is involved. Therefore, automated breast density classification may aid in breast lesion detection and analysis. Several classification methods have been compared and a novel hierarchical classification procedure of combined classifiers with linear discriminant analysis (LDA) is proposed as the best solution to classify the mammograms into the four BIRADS tissue classes. The classification scheme is based on 298 texture features. Statistical analysis to test the normality and homoscedasticity of the data was carried out for feature selection. Thus, only features that are influenced by the tissue type were considered. The novel classification techniques have been incorporated into a CADe system to drive the detection algorithms and tested with 1459 images. The results obtained on the 322 screen-film mammograms (SFM) of the mini-MIAS dataset show that 99.75% of samples were correctly classified. On the 1137 full-field digital mammograms (FFDM) dataset results show 91.58% agreement. The results of the lesion detection algorithms were obtained from modules integrated within the CADe system developed by the authors and show that using breast tissue classification prior to lesion detection leads to an improvement of the detection results. The tools enhance the detectability of lesions and they are able to distinguish their local attenuation without local tissue density constraints.  Read more…

Compact Trip Representation       Wavelet Matrix      

توضیحات خلاصه (Summary):

[Abstract] We present a new Compact Trip Representation ( CTRCTR ) that allows us to manage users’ trips (moving objects) over networks. These could be public transportation networks (buses, subway, trains, and so on) where nodes are stations or stops, or road networks where nodes are intersections. CTRCTR represents the sequences of nodes and time instants in users’ trips. The spatial component is handled with a data structure based on the well-known Compressed Suffix Array ( CSACSA ), which provides both a compact representation and interesting indexing capabilities. We also represent the temporal component of the trips, that is, the time instants when users visit nodes in their trips. We create a sequence with these time instants, which are then self-indexed with a balanced Wavelet Matrix ( WMWM ). This gives us the ability to solve range-interval queries efficiently. We show how CTRCTR can solve relevant spatial and spatio-temporal queries over large sets of trajectories. Finally, we also provide experimental results to show the space requirements and query efficiency of CTRCTR .  Read more…

توضیحات خلاصه (Summary):

[Abstract]: The use of Information and Communication Technologies in higher education has proved to be very effective in different educational environments. A less explored area is their application for evaluation on-line, since it is a different process, with specific components. This work describes a methodology that combines the assessment with multiple choice tests through the virtual environment Moodle and the evaluation by using traditional classroom exams. The proposed mixed methodology ELFF (E-Learning and Face to Face) was implemented during the academic year 2010-11 in the subject Microeconomics: Markets and Competition in the European Union of the double degree in Law and in Business Administration and Management, to assess complementary aspects of the knowledge acquired. The obtained results show that it clearly promotes the participation of students, increases their motivation and improves their competence and so, their performance in terms of qualifications.  Read more…
