Controlling molecular transport in minimal emulsions

open access: yesNature Communications, 2016
Emulsion droplets have many biotechnological applications, such as parallelized single cell analysis. Here, Gruner et al. introduce the concept of the minimal emulsions in a microfluidic device that allows full control of molecular transport between ...

Information-Geometric Optimization with Natural Selection

open access: yesEntropy, 2020
Evolutionary algorithms, inspired by natural evolution, aim to optimize difficult objective functions without computing derivatives. Here we detail the relationship between classical population genetics of quantitative traits and evolutionary ...

Self-organization of signal transduction

open access: yes, 2013
We propose a model of parameter learning for signal transduction, where the objective function is defined by signal transmission efficiency. We apply this to learn kinetic rates as a form of evolutionary learning, and look for parameters which satisfy ...

Persistent accelerations disentangle Lagrangian turbulence

open access: yesNature Communications, 2019
Particles in turbulence, as encountered in the atmosphere or the oceans, experience strongly varying local flow conditions over time. Bentkamp et al. show that this statistical complexity can be broken down into simpler parts, allowing for insights into ...

Emergence of behaviour in a self-organized living matter network

open access: yeseLife, 2022
What is the origin of behaviour? Although typically associated with a nervous system, simple organisms also show complex behaviours. Among them, the slime mold Physarum polycephalum, a giant single cell, is ideally suited to study emergence of behaviour.

Information driven self-organization of complex robotic behaviors [PDF]

open access: yes, 2013
Information theory is a powerful tool to express principles to drive autonomous systems because it is domain invariant and allows for an intuitive interpretation.

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Collective self-caging of active filaments in virtual confinement

open access: yesNature Communications
Motility coupled to responsive behavior is essential for many microorganisms to seek and establish appropriate habitats. One of the simplest possible responses, reversing the direction of motion, is believed to enable filamentous cyanobacteria to form ...

Emergence and melting of active vortex crystals

open access: yesNature Communications, 2021
Whereas transitions from solid- to fluid-like states in systems of active particles have received much attention, the characterization of phase transitions in active fluids with self-organized vortices so far has remained elusive. James et al. take us on

Self-organization of quasi-equilibrium stationary condensation in accumulative ion-plasma devices

open access: yes, 2009
We consider both theoretically and experimentally self-organization process of quasi-equilibrium steady-state condensation of sputtered substance in accumulative ion-plasma devices.
