On modeling airborne infection risk
Yannis Drossinos, Nikolaos I. Stilianakis
Airborne infection risk analysis is usually performed for enclosed spaces where susceptible individuals are exposed to infectious airborne respiratory droplets by inhalation. It is…
Vaccination compartmental epidemiological models for the delta and omicron SARS-CoV-2 variants
J. Cuevas-Maraver, P. G. Kevrekidis, Q. Y. Chen +2
We explore the inclusion of vaccination in compartmental epidemiological models concerning the delta and omicron variants of the SARS-CoV-2 virus that caused the COVID-19 pandemic.…
The role of mobility in the dynamics of the COVID-19 epidemic in Andalusia
Z. Rapti, J. Cuevas-Maraver, E. Kontou +6
Metapopulation models have been a popular tool for the study of epidemic spread over a network of highly populated nodes (cities, provinces, countries) and have been extensively us…
Backcasting COVID-19: A Physics-Informed Estimate for Early Case Incidence
G. A. Kevrekidis, Z. Rapti, Y. Drossinos +4
It is widely accepted that the number of reported cases during the first stages of the COVID-19 pandemic severely underestimates the number of actual cases. We leverage delay embed…
Reaction-diffusion spatial modeling of COVID-19: Greece and Andalusia as case examples
P. G. Kevrekidis, J. Cuevas-Maraver, Y. Drossinos +2
We examine the spatial modeling of the outbreak of COVID-19 in two regions: the autonomous community of Andalusia in Spain and the mainland of Greece. We start with a 0D compartmen…
Morphology-dependent random binary fragmentation of in silico fractal-like agglomerates
Y. Drossinos, A. D. Melas, M. Kostoglou +1
Linear binary fragmentation of synthetic fractal-like agglomerates composed of spherical, equal-size, touching monomers is numerically investigated. Agglomerates of different morph…
Excess Thermal Energy and Latent Heat in Nanocluster Collisional Growth
Huan Yang, Yannis Drossinos, Christopher J. Hogan
Nanoclusters can form and grow by nanocluster-monomer (condensation) and nanocluster-nanocluster (coagulation) collisions. During growth, product nanoclusters have elevated thermal…
Morphology and mobility of synthetic colloidal aggregates
Anastasios D. Melas, Lorenzo Isella, Athanasios G. Konstandopoulos +1
The relationship between geometric and dynamic properties of fractal-like aggregates is studied in the continuum mass and momentum-transfer regimes. The synthetic aggregates were g…
Indirect transmission and the effect of seasonal pathogen inactivation on infectious disease periodicity
Marguerite Robinson, Yannis Drossinos, Nikolaos I. Stilianakis
The annual occurrence of many infectious diseases remains a constant burden to public health systems. The seasonal patterns in respiratory disease incidence observed in temperate r…
Spatial dynamics of airborne infectious diseases
M. Robinson, N. I. Stilianakis, Y. Drossinos
Disease outbreaks, such as those of Severe Acute Respiratory Syndrome in 2003 and the 2009 pandemic A(H1N1) influenza, have highlighted the potential for airborne transmission in i…
On the friction coefficient of straight-chain aggregates
Lorenzo Isella, Yannis Drossinos
A methodology to calculate the friction coefficient of an aggregate in the continuum regime is proposed. The friction coefficient and the monomer shielding factors, aggregate-avera…
Langevin agglomeration of nanoparticles interacting via a central potential
Lorenzo Isella, Yannis Drossinos
Nanoparticle agglomeration in a quiescent fluid is simulated by solving the Langevin equations of motion of a set of interacting monomers in the continuum regime. Monomers interact…
Dynamical Barrier for the Formation of Solitary Waves in Discrete Lattices
P. G. Kevrekidis, J. A. Espinola-Rocha, Y. Drossinos +1
We consider the problem of the existence of a dynamical barrier of ``mass'' that needs to be excited on a lattice site to lead to the formation and subsequent persistence of locali…
Brownian motion of finite-inertia particles in a simple shear flow
Yannis Drossinos, Michael W. Reeks
Simultaneous diffusive and inertial motion of Brownian particles in laminar Couette flow is investigated via Lagrangian and Eulerian descriptions to determine the effect of particl…
