• #### Multiple-time-stepping generalized hybrid Monte Carlo methods ﻿

(2014-12-31)
Performance of the generalized shadow hybrid Monte Carlo (GSHMC) method [1], which proved to be superior in sampling efficiency over its predecessors [2-4], molecular dynamics and hybrid Monte Carlo, can be further improved ...
• #### A multiscale network-based model of contagion dynamics: heterogeneity, spatial distancing and vaccination ﻿

(2021)
Lockdown and vaccination policies have been the major concern in the last year in order to contain the SARS-CoV-2 infection during the COVID-19 pandemic. In this paper we present a model able to evaluate alternative lockdown ...
• #### Multiscale simulations of the antimicrobial peptide maculatin 1.1: Water permeation through disordered aggregates ﻿

(2012-12-31)
The antimicrobial peptide maculatin 1.1 (M1.1) is an amphipathic α-helix that permeabilizes lipid bilayers. In coarse-grained molecular dynamics (CG MD) simulations, M1.1 has previously been shown to form membrane-spanning ...
• #### Neuron-glial Interactions ﻿

(2020-06-07)
Although lagging behind classical computational neuroscience, theoretical and computational approaches are beginning to emerge to characterize different aspects of neuron-glial interactions. This chapter aims to provide ...
• #### No Time at the End of the Tunnel ﻿

(2018-08-21)
Modern atto-second experiments seek to provide an insight into a long standing question: “how much time does a tunnelling particle spend in the barrier?” Traditionally, quantum theory relates this duration to the delay ...
• #### Non-Markovian models of the growth of a polymer chain ﻿

(2015-12-31)
Using simple exactly solvable models, we show that event-dependent time delays may lead to significant non-Poisson effects in the statistics of polymer chain growth. The results are confirmed by stochastic simulation of ...

(2016-06-22)
With the aim of applying numerical methods, we develop a formalism for physiologically structured population models in a new generality that includes con- sumer resource, cannibalism and trophic models. The dynamics at the ...
• #### Numerical equilibrium analysis for structured consumer resource models ﻿

(2010-12-31)
In this paper, we present methods for a numerical equilibrium and stability analysis for models of a size structured population competing for an unstructured resource. We concentrate on cases where two model parameters are ...
