A stochastic view on surface inhomogeneity of nanoparticles

Nature Communications, 2019
Determining the spatial arrangement of molecules on a nanoparticle’s surface is key to understanding its interactions. Here, the authors use dSTORM imaging and probabilistic modelling to map the distribution of fluorophores on a nanoparticle, finding ...

Wavefront Shaping with Varying Degrees of Freedom [PDF]

EPJ Web of Conferences
Optical wavefront shaping employs the linearity of scattering to focus light through scattering media using spatial modulation. By selectively switching off weakly-contributing segments, we significantly improve optimization speeds with minimal intensity

Evolutionary Subnetworks in Complex Systems

, 2009
Links in a practical network may have different functions, which makes the original network a combination of some functional subnetworks. Here, by a model of coupled oscillators, we investigate how such functional subnetworks are evolved and developed ...

Are Innovation Systems Complex Systems?

, 2016
Basically, complex systems are defined as a large number of autonomous entities in interaction, that create several levels of collective organization leading to emergent (and immergent) behavior. In short, complex systems are characterized by the observation that the whole is more than the sum of the parts (Aristotle).

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.
