Extending the Adapted PageRank Algorithm Centrality to Multiplex Networks with Data Using the PageRank Two-Layer Approach

open access: yesSymmetry, 2019
Usually, the nodes’ interactions in many complex networks need a more accurate mapping than simple links. For instance, in social networks, it may be possible to consider different relationships between people.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Functional outcome prediction after partial nephrectomy using R.E.N.A.L. nephrometry, PADUA classification, and Centrality index score

open access: yesUrological Science, 2017
Objective: Several scoring systems have been proposed to quantify surgical complexity, and provide an insight into expected peri- and postoperative surgical outcomes following partial nephrectomy. However, it is still unclear which of the scoring systems

Post‐Pinatubo vegetation index in central Africa

open access: yesGeocarto International, 1994
Abstract On June 15,1991 the Mt. Pinatubo volcano had a major eruption that injected a considerable amount of dust, ash, and sulfur dioxide gas into the atmosphere. This volcanic cloud blocked the amount of energy reaching the Earth's surface causing, in turn, a decrease in NDVI values specifically in the tropics.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

La dificultad de medir.

open access: yesREDES: Revista Hispana para el Análisis de Redes Sociales, 2009
Network analysis has popularized because it has facilitated approaching structural relationships which other methods ignored, however, still some methodological problems remain to be solved in the search of more complex explanations, such as the ...

Assortativity Analysis of Real-World Network Graphs based on Centrality Metrics

open access: yesComputer and Information Science, 2016
Assortativity index ( A. Index ) of real-world network graphs has been traditionally computed based on the degree centrality metric and the networks were classified as assortative, dissortative or neutral if the A.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...
