Design of a flexible analog signal conditioning circuit for DSP-based systems
(Elsevier, 2013)"This paper presents the design of a flexible analog signal conditioning circuit (SCC) able to be reconfigured de- pending on user requirements. The SCC can be employed with DSP-based systems. The design is aimed to be ... -
Physicochemical characterization, elemental speciation and hydrogeochemical modeling of Santa Lucía peloid used for therapeutic uses
(Centro de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México,, 2018)"Santa Lucia peloid is a sediment, extracted from salt mines, used in pelotherapy in Cuban primary health care services. Therefore, in addition to classical quality control analyses of total metal concentrations in sediments, ... -
Rangeland systems in developing nations: conceptual advances and societal implications
(Springer, 2017)"Developing-country rangelands are vast and diverse. They are home to millions who are often poor, politically marginalized, and dependent on livestock for survival. Here we summarize our experiences from six case-study ... -
Magnetic and martensitic transformations in Ni48Co2Mn35In15 melt-spun ribbons
(American Institute of Physics, 2018)"As-solidified Ni48Co2Mn35In15 ribbons were prepared through the melt-spinning method, and their structural, magnetic, magnetocaloric properties, and martensitic transformations were investigated. The inverse martensitic ... -
Transcriptional signature associated with early rheumatoid arthritis and healthy individuals at high risk to develop the disease
(Public Library of Science, 2018)"Background Little is known regarding the mechanisms underlying the loss of tolerance in the early and preclinical stages of autoimmune diseases. The aim of this work was to identify the transcriptional profile and ... -
Effects of stochastic time-delayed feedback on a dynamical system modeling a chemical oscillator
(American Physical Society, 2018)"We examine how stochastic time-delayed negative feedback affects the dynamical behavior of a model oscillatory reaction. We apply constant and stochastic time-delayed negative feedbacks to a point Field-KorosNoyes ... -
Identification of differentially expressed genes potentially involved in the tolerance of Lotus tenuis to long-term alkaline stress
(Elsevier, 2014)"Soil alkalinity is one of the most serious agricultural problems limiting crop yields. The legume Lotus tenuis is an important forage acknowledged by its ability to naturally grow in alkaline soils. To gain insight into ... -
Arabidopsis thaliana polyamine content is modified by the interaction with different Trichoderma species
(Elsevier, 2015)"Plants are associated with a wide range of microorganisms throughout their life cycle, and some interactions result on plant benefits. Trichoderma species are plant beneficial fungi that enhance plant growth and development, ... -
Phase transition systematics in BiVO4 by means of high-pressure-high-temperature Raman experiments
(American Physical Society, 2018)"We report here high-pressure-high-temperature Raman experiments performed on BiVO4. We characterized the fergusonite and scheelite phases (powder and single crystal samples) and the zircon polymorph (nanopowder). The ... -
Removing lateral chromatic aberration in bright field optical microscopy
(Optical Society, 2015)"We present an efficient alternative to remove lateral chromatic aberration (LCA) in bright field light microscopy images. Our procedure is based on error calibration using time-sequential acquisition at different wavelengths, ... -
Transport and diffusion on crystalline surfaces under external forces
(IOP Publishing, 2005)"We present a numerical study of classical particles obeying a Langevin equation and moving on a solid crystalline surface under an external force that may either be constant or modulated by periodic oscillations. We focus ... -
Curved nanostructured materials
(IOP Publishing, 2003)"Graphite is a layered material that is very flexible, in which each layer is able to curve in order to form cages, nanotubes, nanocoils, nanocones, etc. In this paper, we demonstrate that various synthetic routes are ... -
Theoretical characterization of several models of nanoporous carbon
(IOP Publishing, 2003)"Elastic, electronic and vibrational properties of seven models of nanoporous carbon are reported. The studied structures are periodic graphitic arrangements with heptagonal and octagonal rings of carbon, known as Schwarzites. ... -
Evaluation of vascular tone and cardiac contractility in response to silver nanoparticles, using Langendorff rat heart preparation
(Elsevier, 2017)"Silver nanoparticles (AgNPs) have been widely used because of their antimicrobial properties. However, several reports suggest that AgNPs exposure promote cardiac effects that involve nitric oxide (NO) and oxidative stress ... -
Magnetostructural transitions and magnetocaloric effects in Ni50Mn35In14.25B0.75 ribbons
(American Institute of Physics, 2018)"The structural, thermal, and magnetic behaviors, as well as the martensitic phase transformation and related magnetocaloric response of Ni50Mn35In14.25B0.75 annealed ribbons have been investigated using room-temperature ... -
Transitional behaviour in the transformation from active end planes to stable loops caused by annealing
(IOP Publishing, 2003)"Here we investigate the stabilization process on the active outer/inner surfaces (or the end plane of a graphene sheet) for shortened cup-stacked-type carbon nanotubes caused by annealing, utilizing both analytic and ... -
Timbe (Acaciella angustissima) pods extracts reduce the levels of glucose, insulin and improved physiological parameters, hypolipidemic effect, oxidative stress and renal damage in streptozotocin-induced diabetic rats
(MDPI, 2018)"In Mexico one in 14 deaths are caused by diabetes mellitus (DM) or by the macro and microvascular disorders derived from it. A continuous hyperglycemic state is characteristic of DM, resulting from a sustained state of ... -
Recalcitrant deep and shallow nodes in Aristolochia (Aristolochiaceae) illuminated using anchored hybrid enrichment
