Behavior simulation is an effective method to visualize the meaning of mechanical concepts and has been applied in many computer-aided education systems. These simulations are not useful, however, for a learner who has already formulated an erroneous equation. In order to help the learner to recognize and correct the error, simulating the erroneous equation is a promising method. In this paper,...

Quantum information science addresses how the processing and transmission of information are affected by uniquely quantum mechanical phenomena. Combination of two-qubit gates has been used to realize quantum circuits, however, scalability is becoming a critical problem. The use of three-qubit gates may simplify the structure of quantum circuits dramatically. Among them, the controlled-SWAP (Fre...

We discuss the possibility of testing the principle of equivalence with solar neutrinos. If there exists a violation of the equivalence principle quarks and leptons with different flavors may not universally couple with gravity. The method we discuss employs a quantum mechanical phenomenon of neutrino oscillation to probe into the non-universality of the gravitational couplings of neutrinos. We...

Human sensory processes are well understood: hearing, seeing, perhaps even tasting and touch--but we do not understand smell--the elusive sense. That is, for the others we know what stimuli causes what response, and why and how. These fundamental questions are not answered within the sphere of smell science; we do not know what it is about a molecule that ... smells. I report, here, the status ...

In this paper we discuss a new concept of a constitutive kinetic equation which represents a quasicontinuum analog of the conventional continuum mechanical concept of a kinetic relation. Kinetic relations link the velocity of the defect with the driving force and are widely used to model dynamical response of dislocations, cracks and phase boundaries. To illustrate the difference between kineti...

The formation of a superfluid when (4)He is cooled below the characteristic lambda transition temperature is accompanied by intricate quantum mechanical phenomena, including the emergence of a Bose condensate. A combination of path integral and semiclassical techniques is used to calculate the single-particle velocity autocorrelation function across the normal-to-superfluid transition. We find ...
