We introduce an untethered interface that eliminates the annoyance of wires etc. by using air-jets to establish force feedback. Attendees experience interaction with a virtual object that responds to being "touched". The sense of touch is provided by air-jets while visual clues are provided by a projection-based stereo display.
Albumin (Alb) is mixture of reduced and oxidized forms. It is physiologically significant to determine Alb(red)%, which is the proportion of reduced Alb in the sum of Alb. However, reduced Alb in both blood and plasma samples is easily converted to oxidized Alb. Accordingly, the stabilization of Alb in samples is necessary to determine precise Alb(red)%(More)
A comprehensive picture of the ultrafast nonradiative decay mechanisms of three cytosine tautomers (amino-keto, imino-keto, and amino-enol forms) is revealed by high-level ab initio potential energy calculations using the multistate (MS) CASPT2 method and also by on-the-fly excited-state molecular dynamics simulations employing the CASSCF method. To obtain(More)
Minoux considered the manmum balanced /low problem, i.e. the problem of finding a maximum flow in a two-terminal network Af = (V, A) with source s and sink t satisfying the constraint that any arc-flow of Af is bounded by a fixed proportion of the total flow value from s to t , where V is vertex set and A is arc set. Several efficient algorithms, so far,(More)
M. Minoux considered the maximum balanced flow problem, which is a maximum flow problem with an additional constraint described in terms of a balancing rate function. In this paper, we propose an algorithm for the maximum balanced flow problem which is practically fast and simple. When the balancing rate function is constant, the proposed algorithm requires(More)
We use quantum-correction factors to calculate approximately the quantum velocity time-correlation function (TCF) of supercritical Lennard-Jones argon from the classical TCF. We find that for this quite classical system, several different quantum-correction schemes yield essentially identical results for the real and imaginary parts of the quantum TCF, and(More)
A rigorous derivation of the macroscopic governing equations for convective flow in a nanofluid saturated metal foam has been conducted using the volume averaging theory originally developed for analyzing heat and fluid flow in porous media. The nanoparticle conservation equation at a pore scale based on the Buongiorno model has been integrated over a local(More)
