Stability of oscillating hexagons in rotating convection
(2000)
Article
Open AccessBreaking the chiral symmetry, rotation induces a secondary Hopf bifurcation in weakly nonlinear hexagon patterns which gives rise to oscillating hexagons. We study the stability of the oscillating hexagons using three ... -
Sideband instabilities and defects of quasipatterns
(2001)
Article
Open AccessQuasipatterns have been found in dissipative systems ranging from Faraday waves in vertically vibrated fluid layers to nonlinear optics. We describe the dynamics of octagonal, decagonal and dodecagonal quasipatterns by ... -
Spatiotemporal control of cardiac alternans
(Institute of Physics (IOP), 2002)
Article
Restricted access - publisher's policyElectrical alternans are believed to be linked to the onset of life-threatening ventricular arrhythmias and sudden cardiac death. Recent studies have shown that alternans can be suppressed temporally by dynamic feedback ... -
Computational Model of Calcium Signaling in Cardiac Atrial Cells at the Submicron Scale
(2018-12-10)
Article
Open AccessIn cardiac cells, calcium is the mediator of excitation-contraction coupling. Dysfunctions in calcium handling have been identified as the origin of some cardiac arrhythmias. In the particular case of atrial myocytes, ... -
Analyzing policymaking for tuberculosis control in Nigeria
(2018-11-07)
Article
Open AccessToday, tuberculosis (TB) is still one of the major threats to humankind, being the first cause of death by an infectious disease worldwide. TB is a communicable chronic disease that every year affects 10 million people ... -
Congenital and blood transfusion transmission of chagas disease: A framework using mathematical modeling
(2018-11-01)
Article
Open AccessChagas disease or American trypanosomiasis is an important health problem in Latin America. Due to the mobility of Latin American population around the world, countries without vector presence started to report disease ... -
A sounding rocket experiment to control boiling by means of acoustic waves
(2018-01-01)
Article
Open AccessOne of the most critical issues when considering long-term space exploration missions is the management and storage of cryogenic propellants. The exposure of storage tanks to radiation and extreme temperatures implies the ... -
Can systems immunology lead tuberculosis eradication?
(Elsevier, 2018-10-30)
Article
Open Access25 years after the declaration of a Global Emergency by the World Health Organization, tuberculosis (TB) remains a major enemy to the humankind. During this period, much progress has been done to better understand its ... -
Ectopic beats arise from micro-reentries near infarct regions in simulations of a patient-specific heart model
(Nature, 2018-12-01)
Article
Open AccessEctopic beats are known to be involved in the initiation of a variety of cardiac arrhythmias. Although their location may vary, ectopic excitations have been found to originate from infarct areas, regions of micro-fibrosis ... -
Histidine decarboxylase-positive lactic acid bacteria strains and the formation of histamine in ripened cheeses
(2018-09-14)
Article
Open AccessThe relationship between histidine decarboxylase-positive (hdc+) lactic acid bacteria (LAB) counts and the amounts of biogenic amines, particularly histamine, in cheeses made with and without LAB starter were investigated. ... -
Killing many birds with two stones: hypoxia and fibrosis can generate ectopic beats in a human ventricular model
(2018-06-22)
Article
Open AccessDuring cardiac diseases many types of anatomical and functional remodeling of cardiac tissue can occur. In this work, we focus on two conditions: hypoxia and fibrosis, which are part of complex pathological modifications ... -
Development of a computational model of abscess formation
(2018-06-26)
Article
Open AccessIn some bacterial infections, the immune system cannot eliminate the invading pathogen. In these cases, the invading pathogen is successful in establishing a favorable environment to survive and persist in the host organism. ...
