(Theoretical Chemistry Accounts, 2017-03-07)
The study of ion transport in electrochemically active materials for energy storage systems requires simulations on quantum-, atomistic- and meso-scales. The methods accessing these scales not only have to be effective but ...
• #### Enhancing Sampling in Computational Statistics Using Modified Hamiltonians ﻿

(2016-11-15)
The Hamiltonian Monte Carlo (HMC) method has been recognized as a powerful sampling tool in computational statistics. In this thesis, we show that performance of HMC can be dramatically improved by replacing Hamiltonians ...
• #### Estimation of age-specific rates of reactivation and immune boosting of the varicella zoster virus ﻿

(Epidemics, 2016-12-31)
Studies into the impact of vaccination against the varicella zoster virus (VZV) have increasingly focused on herpes zoster (HZ), which is believed to be increasing in vaccinated populations with decreasing infection pressure. ...
• #### An even simpler understanding of quantum weak values ﻿

(Annals of Physics, 2018-01)
We explain the properties and clarify the meaning of quantum weak values using only the basic notions of elementary quantum mechanics.

(Physical Review B - Condensed Matter and Materials Physics, 2011-12-31)
We develop an analytical method to find plasmons generated by microwaves in a two-dimensional electron gas with defects. The excitations are expressed in terms of the wake field of a charged particle moving in plasma. The ...
• #### The Experiment Data Depot: A Web-Based Software Tool for Biological Experimental Data Storage, Sharing, and Visualization ﻿

(ACS Synthetic Biology, 2017-09-30)
Although recent advances in synthetic biology allow us to produce biological designs more efficiently than ever, our ability to predict the end result of these designs is still nascent. Predictive models require large ...
• #### Exploring Li-ion conductivity in cubic, tetragonal and mixed-phase Al-substituted Li7La3Zr2O12 using atomistic simulations and effective medium theory ﻿

(Acta Materialia, 2019-08-15)
Garnet Li7La3Zr2O12 (LLZO) is a promising solid electrolyte candidate for solid-state Li-ion batteries, but at room temperature it crystallizes in a poorly Li-ion conductive tetragonal phase. To this end, partial substitution ...

(EPL, 2015-12-31)
The brain exhibits a wide variety of spatiotemporal patterns of neuronal activity recorded using functional magnetic resonance imaging as the so-called blood-oxygenated-level-dependent (BOLD) signal. An active area of work ...

Chemical gardens in laboratory chemistries ranging from silicates to polyoxometalates, in applications ranging from corrosion products to the hydration of Portland cement, and in natural settings ranging from hydrothermal ...
• #### Functional connectivity of EEG signals under laser stimulation in migraine ﻿

(Frontiers in Human Neuroscience, 2015-12-31)
In previous studies, migraine patients showed abnormalities in pain-related evoked responses, as reduced habituation to repetitive stimulation. In this study, we aimed to apply a novel analysis of EEG bands synchronization ...
• #### Functional Geometry of Human Connectomes ﻿

(SCIENTIFIC REPORTS, 2019-08)
Mapping the brain imaging data to networks, where nodes represent anatomical brain regions and edges indicate the occurrence of fiber tracts between them, has enabled an objective graph-theoretic analysis of human connectomes. ...
