Elastohydrodynamic coupling enhances flow generation by coordinated ciliary beating
Shota Nakano, Shinji Deguchi, Daiki Matsunaga
Ciliary arrays pump fluid at low Reynolds number through non-reciprocal beating and phase coordination between neighbouring cilia. Previous studies have demonstrated that antiplect…
Tuning microswimmer motility by liposome encapsulation: swimming and cargo transport of Chlamydomonas-encapsulating liposome
Koichiro Akiyama, Sota Hamaguchi, Hiromasa Shiraiwa +4
Inspired by biology's use of vesicles for targeted transport, many studies have propelled liposomes with active matter, creating synthetic systems that can be viewed as microscale…
Modeling bacterial flow field with regularized singularities
Yaochen Yang, Daiki Matsunaga, Da Wei +1
The flow field generated by a swimming bacterium serves as a fundamental building block for understanding hydrodynamic interactions between bacteria. Although the flow field genera…
Cell-induced wrinkling patterns on soft substrates
Aleksandra Ardaševa, Varun Venkatesh, Daiki Matsunaga +2
Cells exert traction forces on compliant substrates and can induce surface instabilities that appear as characteristic wrinkling patterns. Here, we develop a mechanical description…
Optimal Undulatory Swimming with Constrained Deformation and Actuation Intervals
Fumiya Tokoro, Hideki Takayama, Shinji Deguchi +2
In nature, many unicellular organisms are able to swim with the help of beating filaments, where local energy input leads to cooperative undulatory beating motion. Here, we investi…
Asymmetric bistability of chiral particle orientation in viscous shear flows
Andreas Zöttl, Francesca Tesser, Daiki Matsunaga +3
The migration of helical particles in viscous shear flows plays a crucial role in chiral particle sorting. Attaching a non-chiral head to a helical particle leads to a rheotactic t…
Field-controlling patterns of sheared ferrofluid droplets
Shunichi Ishida, Yaochen Yang, Fanlong Meng +1
We investigate how ferrofluid droplets suspended in a wall-bounded shear flow can organise when subjected to an external magnetic field. By tuning the magnitude of the external mag…
Wrinkle force microscopy: a new machine learning based approach to predict cell mechanics from images
Honghan Li, Daiki Matsunaga, Tsubasa S. Matsui +4
Combining experiments with artificial intelligence algorithms, we propose a new machine learning based approach to extract the cellular force distributions from the microscope imag…
Magnetic microswimmers exhibit Bose-Einstein-like condensation
Fanlong Meng, Daiki Matsunaga, Benoît Mahault +1
We study an active matter system comprised of magnetic microswimmers confined in a microfluidic channel and show that it exhibits a new type of self-organized behavior. Combining a…
Degenerate states, emergent dynamics and fluid mixing by magnetic rotors
Takuma Kawai, Daiki Matsunaga, Fanlong Meng +2
We investigate the collective motion of magnetic rotors suspended in a viscous fluid under an uniform rotating magnetic field. The rotors are positioned on a square lattice, and lo…
Exploring Graph Neural Networks for Stock Market Predictions with Rolling Window Analysis
Daiki Matsunaga, Toyotaro Suzumura, Toshihiro Takahashi
Recently, there has been a surge of interest in the use of machine learning to help aid in the accurate predictions of financial markets. Despite the exciting advances in this cros…
Image based cellular contractile force evaluation with small-world network inspired CNN: SW-UNet
Li Honghan, Daiki Matsunaga, Tsubasa S. Matsui +2
We propose an image-based cellular contractile force evaluation method using a machine learning technique. We use a special substrate that exhibits wrinkles when cells grab the sub…
