Mixing due to sheared salt fingers is studied by means of direct numerical simulations (DNS) of a doublediffusively unstable shear layer. The focus is on the ‘‘moderate shear’’ case, where shear is strong enough to produce Kelvin–Helmholtz (KH) instability but not strong enough to produce the subharmonic pairing instability. This flow supports both KH and salt-sheet instabilities, and the objec...

The use of fancy graphics can have a mesmerizing effect on simulation novices and, as such, may blind the user to the actual capabilities and valid usages. The visualization of simulations are distinct from other computer graphic media because they are a representation of an abstract of reality (the model) as opposed to a representation of reality. This extended abstract provides examples of vi...

This is a “cheat sheet”, which means that it consists of information packaged in a concise and efficient way so that it can easily be used as a quick reference. The topic is ranks of elliptic curves, mostly over Q. This is a slightly revised version of the handout I wrote as a supplement to my survey talk “Distributions of Ranks of Elliptic Curves” at MSRI’s Connections for Women: Arithmetic St...

We study mixing in a thermohaline staircase by means of direct numerical simulations (DNS). A single saltfingering layer is modeled as a diffusively unstable shear layer of hyperbolic tangent form. Our main interest is the influence of shear, and we focus on what we call the “moderate shear” case. This is the regime where shear is strong enough to produce Kelvin-Helmholtz (KH) instability, but ...

BACKGROUND Certain amount of anticancer drugs is excreted in the urine of patients receiving anticancer drugs, and urinary scattering including anticancer drugs at excretion has become a route of anticancer drug contamination. Therefore, we developed an active carbon sheet (HD safe sheet-U) that prevented diffusion by adsorbing anticancer drugs including that excreted in urine. The present stud...

In the past two decades, as a novel approach for tissue engineering, cell sheet engineering has been proposed by our laboratory. Poly(N-isopropylacrylamide) (PIPAAm), which is a well-known temperature-responsive polymer, has been grafted on tissue culture polystyrene (TCPS) surfaces through an electron beam irradiated polymerization. At 37 °C, where the PIPAAm modified surface is hydrophobic, c...

To estimate the sea level rise (SLR) originating from changes in surface mass balance (SMB) of the Greenland ice sheet (GrIS), we present 21st century climate projections obtained with the regional climate model MAR (Modèle Atmosphérique Régional), forced by output of three CMIP5 (Coupled Model Intercomparison Project Phase 5) general circulation models (GCMs). Our results indicate that in a wa...

This article describes some of the basic principles of A true plane wave does not spread out with increasacoustics and psychoacoustics related to the spatialisation ing distance, so it does not decrease in loudness with of sound. It introduces recording and diffusion technologies, distance. In practice, true plane-wave sources do not including binaural, stereo and surround-sound techniques. exi...
