Graph Convolutional Network-based Feature Selection for High-dimensional and Low-sample Size Data
Can Chen, Scott T. Weiss, Yang-Yu Liu
Feature selection is a powerful dimension reduction technique which selects a subset of relevant features for model construction. Numerous feature selection methods have been propo…
Modeling the Neuromuscular Control System of an Octopus Arm
Tixian Wang, Udit Halder, Ekaterina Gribkova +2
The octopus arm is a neuromechanical system that involves a complex interplay between peripheral nervous system (PNS) and arm musculature. This makes the arm capable of carrying ou…
Energy Shaping Control of a Muscular Octopus Arm Moving in Three Dimensions
Heng-Sheng Chang, Udit Halder, Chia-Hsien Shih +3
Flexible octopus arms exhibit an exceptional ability to coordinate large numbers of degrees of freedom and perform complex manipulation tasks. As a consequence, these systems conti…
A Survey on Hyperlink Prediction
Can Chen, Yang-Yu Liu
As a natural extension of link prediction on graphs, hyperlink prediction aims for the inference of missing hyperlinks in hypergraphs, where a hyperlink can connect more than two n…
Understanding the Spatiotemporal Resolution of Near-Field Photoacoustics from Nanostructures
Hanwei Wang, Yun-Sheng Chen, Yang Zhao
Understanding the mechanism of photoacoustic generation at the nano-scale is key to developing more efficient photoacoustic devices and agents. Unlike the far-field photoacoustic e…
A Sensory Feedback Control Law for Octopus Arm Movements
Tixian Wang, Udit Halder, Ekaterina Gribkova +3
The main contribution of this paper is a novel sensory feedback control law for an octopus arm. The control law is inspired by, and helps integrate, several observations made by bi…
Millimeter-scale topography enables coral larval settlement in wave-driven oscillatory flow
Mark A. Levenstein, Daniel J. Gysbers, Kristen L. Marhaver +8
Larval settlement in wave-dominated, nearshore environments is the most critical life stage for a vast array of marine invertebrates, yet it is poorly understood and virtually impo…
Multi-curvature viscous streaming: flow topology and particle manipulation
Yashraj Bhosale, Giridar Vishwanathan, Tejaswin Parthasarathy +2
Viscous streaming refers to the rectified, steady flows that emerge when a liquid oscillates around an immersed microfeature, typically a solid body or a bubble. The ability of suc…
Artificial confocal microscopy for deep label-free imaging
Xi Chen, Mikhail E. Kandel, Shenghua He +8
Widefield microscopy methods applied to optically thick specimens are faced with reduced contrast due to spatial crosstalk, in which the signal at each point is the result of a sup…
Dropping diversity of products of large US firms: Models and measures
Ananthan Nambiar, Tobias Rubel, James McCaull +2
It is widely assumed that in our lifetimes the products available in the global economy have become more diverse. This assumption is difficult to investigate directly, however, bec…
Friction modulation in limbless, three-dimensional gaits and heterogeneous terrains
Xiaotian Zhang, Noel Naughton, Tejaswin Parthasarathy +1
Motivated by a possible convergence of terrestrial limbless locomotion strategies ultimately determined by interfacial effects, we show how both 3D gait alterations and locomotory…
Three-dimensional geometry and topology effects in viscous streaming
Fan Kiat Chan, Yashraj Bhosale, Tejaswin Parthasarathy +1
Recent studies on viscous streaming flows in two dimensions have elucidated the impact of body curvature variations on resulting flow topology and dynamics, with opportunities for…
Novel Inertial Self-Assembly Dynamics and Long-Range Spatial Ordering of Interacting Droplet Ensembles in Confined Microfluidic Flows
Wenyang Jing, Hee-Sun Han
The multiphase flow of droplets is widespread, both at the industrial and the microscale, for both biological and non-biological applications alike. But the ensemble interactions o…
DNA Supercoiling Drives a Transition between Collective Modes of Gene Synthesis
Purba Chatterjee, Nigel Goldenfeld, Sangjin Kim
Recent experiments showed that multiple copies of the molecular machine RNA polymerase (RNAP) can efficiently synthesize mRNA collectively in the active state of the promoter. Howe…
An unrecognized force in inertial microfluidics
Siddhansh Agarwal, Fan Kiat Chan, Mattia Gazzola +1
Describing effects of small but finite inertia on suspended particles is a fundamental fluid dynamical problem that has never been solved in full generality. Modern microfluidics h…
A remeshed vortex method for mixed rigid/soft body fluid--structure interaction
Yashraj Bhosale, Tejaswin Parthasarathy, Mattia Gazzola
We outline a 2D algorithm for solving incompressible flow--structure interaction problems for mixed rigid/soft body representations, within a consistent framework based on the reme…
Controlling a CyberOctopus Soft Arm with Muscle-like Actuation
Heng-Sheng Chang, Udit Halder, Ekaterina Gribkova +4
This paper presents an application of the energy shaping methodology to control a flexible, elastic Cosserat rod model of a single octopus arm. The novel contributions of this work…
Optimal Control of a Soft CyberOctopus Arm
Tixian Wang, Udit Halder, Heng-Sheng Chang +2
In this paper, we use the optimal control methodology to control a flexible, elastic Cosserat rod. An inspiration comes from stereotypical movement patterns in octopus arms, which…
Time-dependent heterogeneity leads to transient suppression of the COVID-19 epidemic, not herd immunity
Alexei V. Tkachenko, Sergei Maslov, Ahmed Elbanna +3
Epidemics generally spread through a succession of waves that reflect factors on multiple timescales. On short timescales, super-spreading events lead to burstiness and overdispers…
Modeling COVID-19 dynamics in Illinois under non-pharmaceutical interventions
George N. Wong, Zachary J. Weiner, Alexei V. Tkachenko +3
We present modeling of the COVID-19 epidemic in Illinois, USA, capturing the implementation of a Stay-at-Home order and scenarios for its eventual release. We use a non-Markovian a…
