Hydrodynamics of soft active matter
This review summarizes theoretical progress in the field of active matter, placing it in the context of recent experiments, and highlights the experimental relevance of various semimicroscopic derivations of the continuum theory for describing bacterial swarms and suspensions, the cytoskeleton of living cells, and vibrated granular material.
Hydrodynamic fluctuations and instabilities in ordered suspensions of self-propelled particles.
The hydrodynamic equations for suspensions of self-propelled particles (SPPs) with spontaneous orientational order are constructed, and a number of striking, testable predictions are made.
The Mechanics and Statistics of Active Matter
Active particles contain internal degrees of freedom with the ability to take in and dissipate energy and, in the process, execute systematic movement. Examples include all living organisms and their
Rheology of active-particle suspensions.
The phenomena of cytoplasmic streaming, elastotaxis, and active mechanosensing find natural explanations within the model of hydrodynamic velocity, concentration, and stress fields in a suspension of active, energy-dissipating particles.
Long-Lived Giant Number Fluctuations in a Swarming Granular Nematic
Working with a fluidized monolayer of macroscopic rods in the nematic liquid crystalline phase, giant number fluctuations consistent with a standard deviation growing linearly with the mean are found, in contrast to any situation where the central limit theorem applies.
Anomalous heat conduction in one-dimensional momentum-conserving systems.
We show that for one-dimensional fluids the thermal conductivity generically diverges with system size L as L(1/3), as a result of momentum conservation. Our results are consistent with the
Risperidone monotherapy for post-traumatic stress disorder related to sexual assault and domestic abuse in women
Risperidone monotherapy was more effective than placebo in the treatment of post-traumatic stress disorder and a significant main effect exists for visits using the Treatment Outcomes Post-traumatic Stress Disorder Scale-8 raw score.
Active membrane fluctuations studied by micropipet aspiration.
It is shown that a natural choice of the parameters quantifying the strength of the active noise explains both the large amplitude of the observed effects and its remarkable insensitivity to the active-center density in the investigated range.
Effect of Antidepressant Switching vs Augmentation on Remission Among Patients With Major Depressive Disorder Unresponsive to Antidepressant Treatment: The VAST-D Randomized Clinical Trial
Among a predominantly male population with major depressive disorder unresponsive to antidepressant treatment, augmentation with aripiprazole resulted in a statistically significant but only modestly increased likelihood of remission during 12 weeks of treatment compared with switching to bupropion monotherapy.
