Nonreciprocal interactions induce persistent active clusters in binary colloids Open
We study binary colloids under AC electric fields, where electrohydrodynamic (EHD) flows generate nonreciprocal interactions. Mixing particles of different sizes produces self-propelled pairs that fragment and reassemble into persistent ac…

Simple mathematical model for a pairing-induced motion of active and passive particles Open
We propose a simple mathematical model that describes a pairing-induced motion of active and passive particles in a two-dimensional system, which is motivated by our previous paper [Ishikawa et al., Phys. Rev. E \textbf{106} (2022) 024604]…

Droplet duos on water display pairing, autonomous motion, and periodic eruption Open
Under non-equilibrium conditions, liquid droplets dynamically couple with their milieu through the continuous flux of matter and energy, forming active systems capable of self-organizing functions reminiscent of those of living organisms. …

Pairing-induced motion of source and inert particles driven by surface tension Open
We experimentally and theoretically investigate systems with a pair of source and inert particles that interact through a concentration field. The experimental system comprises a camphor disk as the source particle and a metal washer as th…

Analysis of biological noise in the flagellar length control system Open
Any proposed mechanism for organelle size control should be able to account not only for average size but also for the variation in size. We analyzed cell-to-cell variation and within-cell variation of length for the two flagella in Chlamy…

Development and Application of High-Performance Frictional Gas Cushion Device Open
Recent ultrahigh-tensile-strength steel sheets have become indispensable for improving fuel economy through their incorporation into skeletal parts of automobiles to reduce the weight. To enable the forming of ultrahigh-tensile-strength st…

Effect of filling ratio on the thermal performance for a long vertical heat pipe Open
This paper presents effect of filling ratio on the transient and steady thermal performance for a long vertical heat pipe. This heat pipe consists of three sections: cooling section, heating section and sub-heating section. Sub heating sec…

Pressure Gradient Effects on Transition Location over Axisymmetric Bodies at Incidence in Supersonic Flow: Progress Report of JAXA-NASA Joint Research Project on Supersonic Boundary Layer Transition Part 2 Open
Boundary layer transition along the leeward symmetry plane of axisymmetric bodies at nonzero angle of incidence in supersonic flow was investigated numerically as part of joint research between the Japan Aerospace Exploration Agency (JAXA)…

Development of Inverse Design System for Supersonic Natural Laminar Flow Wing on High Reynolds Number Condition Open
A natural laminar flow wing was designed using a computational-fluid-dynamics-based inverse design method of supersonic transport at high-Reynolds number condition to reduce the friction drag of a large supersonic commercial transport. Des…
