Hartman effect and weak measurements that are not really weak
(Physical Review A - Atomic, Molecular, and Optical Physics, 2011-12-31)We show that in wave packet tunneling, localization of the transmitted particle amounts to a quantum measurement of the delay it experiences in the barrier. With no external degree of freedom involved, the envelope of the ... -
Hidden electronic rule in the "cluster-plus-glue-Atom" model
(Scientific Reports, 2016-10-01)Electrons and their interactions are intrinsic factors to affect the structure and properties of materials. Based on the “cluster-cluster-plus-glue-atom” model, an electron counting rule for complex metallic alloys (CMAs) ... -
Higher-order nonlinear electromechanical effects in wurtzite GaN/AlN quantum dots
(Journal of Physics Condensed Matter, 2010-12-31)As we demonstrated earlier, conventional mathematical models based on linear approximations may be inadequate in the analysis of properties of low-dimensional nanostructures and band structure calculations. In this work, ... -
How does radiofrequency ablation efficacy depend on the stiffness of the cardiac tissue? Insights from a computational model
(2019)Objective. Radiofrequency catheter ablation (RFCA) is an effective treatment for the elimination of cardiac arrhythmias, however it is not exempt from complications that can risk the patients’ life. The efficacy of the ... -
Impact of competitive processes on controlled radical polymerization
(Macromolecules, 2014-12-31)The kinetics of radical polymerization have been systematically studied for nearly a century and in general are well understood. However, in light of recent developments in controlled radical polymerization many kinetic ... -
Incorporating landscape heterogeneities in the spread of an epidemics in wildlife
(Complex Systems; Control of Infectious Diseases, Extended Abstracts 2013. Ã lvaro Corral, Anna Deluca, Francesc Font-Clos, Pilar Guerrero, Andrei Korobeinikov, Francesco Massucci eds., Springer,.http://dx.doi.org/10.1007/978-3-319-08138-0_19", 2014-12-31)One of the main difficulties in the modeling and numerical simulation of the spread of an infectious disease in wildlife resides in properly taking into account the heterogeneities of the landscape. Forests, plains and ... -
Influence of electromechanical effects and wetting layers on band structures of AlN/GaN quantum dots and spin control
(Journal of Applied Physics, 2010-12-31)In a series of recent papers we demonstrated that coupled electromechanical effects can lead to pronounced contributions in band structure calculations of low dimensional semiconductor nanostructures (LDSNs) such as quantum ... -
Information Flow between Resting-State Networks
(Brain Connectivity, 2015-12-31)The resting brain dynamics self-organize into a finite number of correlated patterns known as resting-state networks (RSNs). It is well known that techniques such as independent component analysis can separate the brain ... -
Interference mechanism of seemingly superluminal tunneling
(Physical Review A - Atomic, Molecular, and Optical Physics, 2013-12-31)Apparently "superluminal" transmission, e.g., in quantum tunneling and its variants, occurs via a subtle interference mechanism which allows reconstruction of the entire spatial shape of a wave packet from its front tail. ... -
An introduction to mathematical and numerical modeling in heart electrophysiology
(2016)The electrical activation of the heart is the biological process that regulates the contraction of the cardiac muscle, allowing it to pump blood to the whole body. In physiological conditions, the pacemaker cells of the ... -
Is minimising the convergence rate the best choice for efficient Optimized Schwarz preconditioning in heterogeneous coupling? The Stokes-Darcy case
(2019)Optimized Schwarz Methods (OSM) are domain decomposition techniques based on Robin-type interface condition that have became increasingly popular in the last two decades. Ensuring convergence also on non-overlapping ... -
The JBEI quantitative metabolic modeling library (jQMM): a python library for modeling microbial metabolism
(BMC Bioinformatics, 2017-01-01)Modeling of microbial metabolism is a topic of growing importance in biotechnology. Mathematical modeling helps provide a mechanistic understanding for the studied process, separating the main drivers from the circumstantial ... -
Lagged and instantaneous dynamical influences related to brain structural connectivity
(Frontiers in Psychology, 2015-12-31)Contemporary neuroimaging methods can shed light on the basis of human neural and cognitive specializations, with important implications for neuroscience and medicine. Indeed, different MRI acquisitions provide different ... -

Low-traffic limit and first-passage times for a simple model of the continuous double auction
(Physica A: Statistical Mechanics and its Applications, 2017-05)We consider a simplified model of the continuous double auction where prices are integers varying from 1 to $N$ with limit orders and market orders, but quantity per order limited to a single share. For this model, the ... -
