Hartman effect and weak measurements that are not really weak
Sokolovski, D.; Akhmatskaya, E.
(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
Du, J.; Dong, C.; Melnik, R.; Kawazoe, Y.; Wen, B. (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
Bahrami-Samani, M.; Patil, S.R.; Melnik, R. (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 ... -
Hyperactivation of monocytes and macrophages in MCI patients contributes to the progression of Alzheimer's disease

Background: Alzheimer’s disease (AD) is the most common neurodegenerative disease ultimately manifesting as clinical dementia. Despite considerable effort and ample experimental data, the role of neuroinflammation related ... -
Immunosenescence and Altered Vaccine Efficiency in Older Subjects: A Myth Difficult to Change
Fülöp, T.; Larbi, A.; Pawelec, G.; Cohen, A.; Provost, G.; Khalil, A.; Lacombe, G.; Rodrigues, S.; Desroches, M.; Hirokawa, K.; Franceschi, C.; Witkowski, J.M. (2022-04-01)
Organismal ageing is associated with many physiological changes, including differences in the immune system of most animals. These differences are often considered to be a key cause of age-associated diseases as well as ... -
Impact of competitive processes on controlled radical polymerization
Ballard, N.; Rusconi, S.; Akhmatskaya, E.; Sokolovski, D.; de La Cal, J.C.; Asua, J.M. (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 ... -
The Impact of Serotype Cross-Protection on Vaccine Trials: DENVax as a Case Study
Aguiar, M.; Stollenwerk, N. (2020-11)
There is a growing public health need for effective preventive interventions against dengue, and a safe, effective and affordable dengue vaccine against the four serotypes would be a significant achievement for disease ... -
Incorporating landscape heterogeneities in the spread of an epidemics in wildlife
(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 ... -
Inflection, Canards and Folded Singularities in Excitable Systems: Application to a 3D FitzHugh–Nagumo Model
Uria-Albizuri, J.; Desroches, M.; Krupa, M.; Rodrigues, S. (2020-09-07)
Specific kinds of physical and biological systems exhibit complex Mixed-Mode Oscillations mediated by folded-singularity canards in the context of slow-fast models. The present manuscript revisits these systems, specifically ... -
Influence of electromechanical effects and wetting layers on band structures of AlN/GaN quantum dots and spin control
Prabhakar, S.; Melnik, R. (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
Diez, I.; Erramuzpe, A.; Escudero, I.; Mateos, B.; Cabrera, A.; Marinazzo, D.; Sanz-Arigita, E.J.; Stramaglia, S.; Cortes Diaz, J.M. (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
Sokolovski, D.; Akhmatskaya, E. (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 ... -
