Experimental study of enhanced flow asymmetry due to viscoelasticity: An assessment of viscoelastic constitutive models

Flow past an asymmetrically confined cylinder of shear-thinning viscoelastic polymer solutions has been experimentally investigated. We show that the flow asymmetry induced by the asymmetric geometry is enhanced at Weissenberg numbers (Wi) above unity; that is, the flow in the no...

A three-dimensional morphoelastic model for self-oscillations in polyelectrolyte hydrogel filaments

Abstract We introduce a three-dimensional model for polyelectrolyte hydrogel filaments operating in a fluid environment under an electric field. The formulation builds on a morphoelastic framework for inextensible and unshearable rods, such that the filament’s activity is encoded...

pCORE, a set of open modular plasmids compatible with golden gate assembly

Abstract Modular DNA assembly based Golden Gate cloning (MoClo) is a widely used framework to assemble genetic constructs. A number of MoClo “destination vectors” have been developed, however, available options are still limited with regards to copy number and antibiotic resistan...

Artificial hibernation reveals synaptic engram architecture associated with memory retention

Memories leave lasting physical changes at the synaptic level. Although stable, larger spines are thought to support memory, the high turnover of dendritic spines and the drifting of neuronal representations after memory formation suggest alternative possibilities. To elucidate t...

Efficient Graph State Generation in Linear Optics

Graph states are central resources for quantum information processing, supporting applications in computation, communication, and error correction. In photonic systems, they are typically assembled from smaller entangled states using probabilistic fusion gates, which demand many...

Genomic resources of Ascidiella aspersa and comparative analysis across tunicates reveal class-level features and evolutionary diversification

Ascidiella aspersa is an invasive tunicate and one of the closest relatives of vertebrates. Despite its ecological nuisance, A. aspersa is anticipated to be a valuable model organism for developmental studies due to its remarkably transparent embryos. However, annotated genome as...

A suspension of heavy Kolmogorov-size spheres suppresses the inertial cascade in homogeneous and isotropic turbulence

The effect of Kolmogorov-size spherical particles on homogeneous and isotropic turbulence is investigated using particle-resolved direct numerical simulations at an unladen Taylor-scale Reynolds number of 150 <mml:math xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:mnf="http://...
