Physical Chemistry of Dust: Weak Intermolecular Interactions in Molecular Nanoparticles
(2006)ChimiaLarge weakly bound molecular aggregates are ubiquitous: As atmospheric aerosols they influence the quality of the air and have a significant impact on our climate. Furthermore pharmaceuticals in the form of nanoparticles are required to achieve a targeted drug delivery. In all these fields, physical-chemical methods play a crucial role for the preparation and characterization of this type of matter. Apart from such experimental efforts, ...Journal Article -

Metaheuristic design of feedforward neural networks: A review of two decades of research
(2017)Engineering Applications of Artificial IntelligenceOver the past two decades, the feedforward neural network (FNN) optimization has been a key interest among the researchers and practitioners of multiple disciplines. The FNN optimization is often viewed from the various perspectives: the optimization of weights, network architecture, activation nodes, learning parameters, learning environment, etc. Researchers adopted such different viewpoints mainly to improve the FNN's generalization ...Journal Article -
Effects of sampling effort on biodiversity patterns estimated from environmental DNA metabarcoding surveys
(2018)Scientific ReportsEnvironmental DNA (eDNA) metabarcoding can greatly enhance our understanding of global biodiversity and our ability to detect rare or cryptic species. However, sampling effort must be considered when interpreting results from these surveys. We explored how sampling effort influenced biodiversity patterns and nonindigenous species (NIS) detection in an eDNA metabarcoding survey of four commercial ports. Overall, we captured sequences from ...Journal Article -
H. pylori-Induced DNA Strand Breaks Are Introduced by Nucleotide Excision Repair Endonucleases and Promote NF-kappaB Target Gene Expression
(2015)Cell ReportsThe human bacterial pathogen Helicobacter pylori exhibits genotoxic properties that promote gastric carcinogenesis. H. pylori introduces DNA double strand breaks (DSBs) in epithelial cells that trigger host cell DNA repair efforts. Here, we show that H. pylori-induced DSBs are repaired via error-prone, potentially mutagenic non-homologous end-joining. A genome-wide screen for factors contributing to DSB induction revealed a critical role ...Journal Article -

The equation of motion for supershear frictional rupture fronts
(2018)Science AdvancesThe rupture fronts that mediate the onset of frictional sliding may propagate at speeds below the Rayleigh wave speed or may surpass the shear wave speed and approach the longitudinal wave speed. While the conditions for the transition from sub-Rayleigh to supershear propagation have been studied extensively, little is known about what dictates supershear rupture speeds and how the interplay between the stresses that drive propagation and ...Journal Article -
Mathematical Variables as Indigenous Concepts
(2009)International Studies in the Philosophy of ScienceThis text explores the semiotic status of algebraic terms. To do that we import a structural and post-structural train of thought going from Mauss and Lévi-Strauss to Baudrillard and Derrida. We import these authors' semiotic thinking from the register of indigenous concepts (such as mana), and apply it to the register of algebra via a concrete case study of generating functions. The purpose of this experiment is to provide a philosophical ...Journal Article -
On the metric, topological and functional structures of urban networks
(2008)Physica A: Statistical Mechanics and its ApplicationsAxial Graphs are networks whose nodes are linear axes in urban space, and edges represent intersections of such axes. These graphs are used in urban planning and urban morphology studies. In this text we analyse distance distributions between nodes in axial graphs, and show that these distributions are well approximated by rescaled Poisson distributions. We then demonstrate a correlation between the parameters governing the distance ...Journal Article
