Controlling assembly and oscillations of elastic membranes with an active fluid

Kavli Affiliate: Mark Bowick | First 5 Authors: John Berezney, Sattvic Ray, Itamar Kolvin, Mark Bowick, Seth Fraden | Summary: We use the chaotic flows generated by a microtubule-based active fluid to assemble self-binding actin filaments into a thin elastic sheets. Starting from a uniformly dispersed state, active flows drive the motion of actin filaments, […]

Cross-sectional imaging of speed-of-sound distribution using photoacoustic reversal beacons

Kavli Affiliate: Yi Zhou | First 5 Authors: Yang Wang, Danni Wang, Liting Zhong, Yi Zhou, Qing Wang | Summary: Photoacoustic tomography (PAT) enables non-invasive cross-sectional imaging of biological tissues, but it fails to map the spatial variation of speed-of-sound (SOS) within tissues. While SOS is intimately linked to density and elastic modulus of tissues, […]

$boldsymbol{Steiner}$-Hardness: A Query Hardness Measure for Graph-Based ANN Indexes

Kavli Affiliate: Cheng Peng | First 5 Authors: Zeyu Wang, Qitong Wang, Xiaoxing Cheng, Peng Wang, Themis Palpanas | Summary: Graph-based indexes have been widely employed to accelerate approximate similarity search of high-dimensional vectors. However, the performance of graph indexes to answer different queries varies vastly, leading to an unstable quality of service for downstream […]

Observational Signatures of Traversable Wormholes

Kavli Affiliate: Cheng Peng | First 5 Authors: Yiqian Chen, Lang Cheng, Peng Wang, Haitang Yang, | Summary: In this paper, we study the observational signatures of traversable Simpson-Visser wormholes illuminated by luminous celestial spheres and orbiting hot spots. We demonstrate that when light sources and observers are on the same side of the wormholes, […]
