Humic Substances Mediate Anaerobic Methane Oxidation Linked to Nitrous Oxide Reduction in Wetland Sediments
(Frontiers Media S.A., 2020)"Humic substances are redox-active organic molecules, which play pivotal roles in several biogeochemical cycles due to their electron-transferring capacity involving multiple abiotic and microbial transformations. Based ... -
Thermodynamic Formalism in Neuronal Dynamics and Spike Train Statistics
(MDPI, 2020)"The Thermodynamic Formalism provides a rigorous mathematical framework for studying quantitative and qualitative aspects of dynamical systems. At its core, there is a variational principle that corresponds, in its simplest ... -
Bioinformatic Analysis and Biophysical Characterization Reveal Structural Disorder in G0S2 Protein
(American Chemical Society, 2020)"G0S2 is a small protein of 103 residues in length that is involved in multiple cellular processes. To date, several reports have shown that G0S2 functions by making direct protein杙rotein interactions with key proteins. ... -
Biohydrogen production from cheese whey powder by Enterobacter asburiae: Effect of operating conditions on hydrogen yield and chemometric study of the fermentative metabolites
(Elsevier, 2020)"In this study, the response surface methodology (RSM) with a central composite design (CCD) was applied to evaluate the effect of temperature, initial pH and cheese whey powder concentration (CWP) on the hydrogen yield ... -
Determining the scale at which variation in a single gene changes population yields
(eLife Sciences Publications, Ltd., 2020)"Plant trait diversity is known to influence population yield, but the scale at which this happens remains unknown: divergent individuals might change yields of immediate neighbors (neighbor scale) or of plants across a ... -
Multistability Emergence through Fractional-Order-Derivatives in a PWL Multi-Scroll System
(MDPI, 2020)"In this paper, the emergence of multistable behavior through the use of fractional-order-derivatives in a Piece-Wise Linear (PWL) multi-scroll generator is presented. Using the integration-order as a bifurcation parameter, ... -
Electronic implementation dataset to monoparametric control the number of scrolls generated
(Elsevier, 2020)"The increasing usage of chaotic systems in the development of security systems, from mobile surveillance devices to the implementation of secure communication systems, leads to devising analog electronic implementations ... -
Multistable Systems with Hidden and Self-Excited Scroll Attractors Generated via Piecewise Linear Systems
(Hindawi, 2020)"In this work, we present an approach to design a multistable system with one-directional (1D), two-directional (2D), and three-directional (3D) hidden multiscroll attractor by defining a vector field on with an even ... -
Derivation of a continuous time dynamic planar system with two unstable foci from a three-dimensional chaotic piecewise linear system
(American Institute of Physics, 2020)"In this paper, we introduce a class of continuous time dynamical planar systems that is capable of generating attractors in the plane by means of the use of hysteresis and at least two unstable foci. This class of systems ... -
Semiconducting Nanocrystalline Bismuth Oxychloride (BiOCl) for Photocatalytic Reduction of CO2
(MDPI, 2020)"The reduction of CO2 is relevant for the production of compounds as part of the carbon capture and utilization research approaches. Thus, photocatalytic reduction of CO2 over a tailored BiOCl-based photocatalyst (BTEG) ... -
Anomalous temperature regimen in the near-surface soil layer of Tlamacas hill and its relation to activity of Popocatépetl Volcano, Mexico
(EDP Sciences, 2020)"This article describes anomalous changes in the diurnal behavior of the temperature measured in the near-surface soil at the Tlamacas monitoring site, Popocatépetl. Results of the statistical analysis show two essential ... -
Germination of seven species of shrubs in semiarid central Mexico: Effect of drought and seed size
(Sociedad Botánica de México, 2020)"Background: In semiarid ecosystems, many plant species are tolerant to drought. However, increased aridity as a result of climatic change could modify the capacity of germination and establishment. Hypothesis: Under ... -
Seed traits and germination in the Cactaceae family: A review across Americas
(Sociedad Botánica de México, 2020)"Background: Cactaceae is the fifth taxonomic group with the highest proportion of threatened species and among the angiosperms, the most vulnerable to human disturbance. One way to contribute to the preservation of this ... -
One-Pot Synthesis of Anatase, Rutile-Decorated Hydrogen Titanate Nanorods by Yttrium Doping for Solar H2 Production
(American Chemical Society, 2020)"We have prepared yttrium (Y)-doped hydrogen titanate nanorods (HTN) by a microwave-assisted hydrothermal method. Y-doped HTN showed much improved photocatalytic activities for both H2 evolution and dye decomposition. H2 ... -
