Controlling topological defects and contractile flow in confined nematic cell population
Ryo Ienaga, Kazusa Beppu, Yusuke T. Maeda
Topological defects in nematically aligned cell populations play a critical role in modulating collective motion, from microbial colonies to epithelial tissues. Despite the potenti…
Geometry-Induced Dynamics of Confined Chiral Active Matter
Archit Negi, Kazusa Beppu, Yusuke T. Maeda
Controlling the motion of active matter is a central issue that has recently garnered significant attention in fields ranging from non-equilibrium physics to chemical engineering a…
Negative autoregulation controls size scaling in confined gene expression reactions
Yusuke T. Maeda
Gene expression via transcription-translation is the most fundamental reaction to sustain biological systems, and complex reactions such as this one occur in a small compartment of…
Tailoring collective motion of kinesin-driven microtubules via topographic landscapes
Shunya Araki, Kazusa Beppu, Arif Md. Rashedul Kabir +2
Biomolecular motor proteins that generate forces by consuming chemical energy obtained from ATP hydrolysis are pivotal for organizing broad cytoskeletal structures in living cells.…
Phase separation and protein partitioning in compartmentalized cell-free expression reactions
Shuzo Kato, David Garenne, Vincent Noireaux +1
Liquid-liquid phase separation (LLPS) is important to control a wide range of reactions from gene expression to protein degradation in a cell-sized space. To bring a better underst…
Examining the assembly pathways and active microtubule mechanics underlying spindle self-organization
Lucan Yan, Tatsuya Fukuyama, Megumi Yamaoka +2
The bipolar organization of the microtubule-based mitotic spindle is essential for the faithful segregation of chromosomes in cell division. Despite our extensive knowledge of gene…
Why epithelial cells collectively move against a traveling signal wave
Tatsuya Fukuyama, Hiroyuki Ebata, Akihisa Yamamoto +6
The response of cell populations to external stimuli plays a central role in biological mechanical processes such as epithelial wound healing and developmental morphogenesis. Wave-…
Edge Current and Pairing Order Transition in Chiral Bacterial Vortex
Kazusa Beppu, Ziane Izri, Tasuku Sato +3
We report the selective stabilization of chiral rotational direction of bacterial vortices, from turbulent bacterial suspension, in achiral circular microwells sealed by an oil-wat…
Randomness and optimality in enhanced DNA ligation with crowding effects
Takaharu Y. Shiraki, Ken-ichiro Kamei, Yusuke T. Maeda
Enzymatic ligation is essential for the synthesis of long DNA. However, the number of ligated products exponentially decays as the DNA synthesis proceeds in a random manner. The co…
Thermal Molecular Focusing: Tunable Cross Effect of Phoresis and Advection
Tatsuya Fukuyama, Sho Nakama, Yusuke T. Maeda
The control of solute fluxes through either microscopic phoresis or hydrodynamic advection is a fundamental way to transport molecules, which are ubiquitously present in nature and…
Geometry-driven collective ordering of bacterial vortices
Kazusa Beppu, Ziane Izri, Jun Gohya +3
Controlling the phases of matter is a challenge that spans from condensed materials to biological systems. Here, by imposing a geometric boundary condition, we study controlled col…
A new search for the and decays
J. K. Ahn, K. Y. Baek, S. Banno +87
We searched for the -violating rare decay of neutral kaon, , in data from the first 100 hours of physics running in 2013 of the J-PARC KOTO experimen…
Oscillation and collective conveyor of water-in-oil droplets by microfluidic bolus flow
Takuya Ohmura, Masatoshi Ichikawa, Ken-ichiro Kamei +1
Microfluidic techniques have been extensively developed to realize micro-total analysis systems in a small chip. For microanalysis, electro-magnetic forces have generally been util…
Electric-field control of spin accumulation signals in silicon at room temperature
Y. Ando, Y. Maeda, K. Kasahara +8
We demonstrate spin-accumulation signals controlled by the gate voltage in a metal-oxide-semiconductor field effect transistor structure with a Si channel and a CoFe/-Si con…
Bias current dependence of spin accumulation signals in a silicon channel detected by a Schottky tunnel contact
Y. Ando, K. Kasahara, K. Yamane +6
We study the electrical detection of spin accumulation at a ferromagnet-silicon interface, which can be verified by measuring a Hanle effect in three-terminal lateral devices. The…
