Time series irreversibility: a visibility graph approach [PDF]
, 2011 We propose a method to measure real-valued time series irreversibility which combines two differ- ent tools: the horizontal visibility algorithm and the Kullback-Leibler divergence.

Aplicaciones de las enzimas lacasas de Pleurotus ostreatus
Mexican Journal of Biotechnology, 2017 La producción de enzimas extracelulares de hongos filamentosos ha sido ampliamente desarrollada mediante el uso de fermentación sumergida. Sin embargo, la fermentación en estado sólido es una alternativa adecuada para la producción de enzimas dada las características fisiológicas y morfológicas de estos hongos.

The roundtable: an abstract model of conversation dynamics
, 2010 Is it possible to abstract a formal mechanism originating schisms and governing the size evolution of social conversations? In this work a constructive solution to such problem is proposed: an abstract model of a generic N-party turn-taking conversation.

Quasiperiodic graphs at the onset of chaos [PDF]
, 2013 We examine the connectivity fluctuations across networks obtained when the horizontal visibility (HV) algorithm is used on trajectories generated by nonlinear circle maps at the quasiperiodic transition to chaos.

Combining cluster number counts and galaxy clustering
, 2016 The abundance of clusters and the clustering of galaxies are two of the important cosmological probes for current and future large scale surveys of galaxies, such as the Dark Energy Survey.

Quasiperiodic graphs: structural design, scaling and entropic properties [PDF]
, 2012 A novel class of graphs, here named quasiperiodic, are constructed via application of the Horizontal Visibility algorithm to the time series generated along the quasiperiodic route to chaos. We show how the hierarchy of mode-locked regions represented by

Azimuthal Anisotropy in High Energy Nuclear Collision - An Approach based on Complex Network Analysis [PDF]
, 2018 Recently, a complex network based method of Visibility Graph has been applied to confirm the scale-freeness and presence of fractal properties in the process of multiplicity fluctuation.

Mitigating technology gaps' contribution to international income inequality
Economic Inquiry, Volume 64, Issue 1, Page 131-166, January 2026.Abstract This replication study revisits a 2023 analysis by Sampson on the impact of international technology gaps on income inequality, trade, and wages. We extend the original framework by using broader patent metrics from PATSTAT, expanding the country sample and time frame, and testing alternative calibrations.

Non-Gaussianity from extragalactic point-sources
, 2012 The population of compact extragalactic sources contribute to the non-Gaussianity at Cosmic Microwave Background frequencies. We study their non-Gaussianity using publicly available full-sky simulations.

Helicobacter, Volume 31, Issue 1, January/February 2026.ABSTRACT Background and Aims Previous antibiotic use influences Helicobacter pylori antibiotic resistance. This study evaluated how prior population‐level macrolide (especially clarithromycin) use affects H. pylori eradication success in naïve patients. Methods Retrospective, multicenter, ecological study. Multivariate logistic regression was performed
