You better watch out: US COVID-19 wave dynamics versus vaccination strategy
Giacomo Cacciapaglia, Corentin Cot, Anna Sigridur Islind +2
We employ the epidemic Renormalization Group (eRG) framework to understand, reproduce and predict the COVID-19 pandemic diffusion across the US. The human mobility across different…
Query-Competitive Sorting with Uncertainty
Magnús M. Halldórsson, Murilo S. de Lima
We study the problem of sorting under incomplete information, when queries are used to resolve uncertainties. Each of data items has an unknown value, which is known to lie in…
Dynamics of a Field Emitted Beam from a Microscopic Inhomogeneous Cathode
Kristinn Torfason, Anna Sitek, Andrei Manolescu +1
We investigate by molecular dynamics simulations [arXiv:1412.4537 [physics.plasm-ph], arXiv:1608.06789 [physics.plasm-ph]] a beam of electrons released via field emission from a pl…
Changes in mobility patterns in Europe during the COVID-19 pandemic: Novel insights using open source data
Anna Sigridur Islind, María Óskarsdóttir, Harpa Steingrímsdóttir
The COVID-19 pandemic has changed the way we act, interact and move around in the world. The pandemic triggered a worldwide health crisis that has been tackled using a variety of s…
Tight Bounds on Subexponential Time Approximation of Set Cover and Related Problems
Marek Cygan, Magnús M. Halldórsson, Guy Kortsarz
We show that Set Cover on instances with elements cannot be approximated within -factor in time exp(, for any and any , assuming the Expo…
Postural control adaptation and habituation during vibratory proprioceptive stimulation: an HD-EEG investigation of cortical recruitment and kinematics
Fabio Barollo, Rún Friðriksdóttir, Kyle J. Edmunds +6
The objective of the present work is to measure postural kinematics and power spectral variation from HD-EEG to assess changes in cortical activity during adaptation and habituatio…
