High Sensitivity Strain Sensors Using Four-Core Fibers through a Corner-Core Excitation

Micromachines, 2022
A weakly-coupled multicore fiber can generate supermodes when the multi-cores are closer to enter the evanescent power coupling region. The high sensitivity strain sensors using tapered four-core fibers (FCFs) were demonstrated.

Fast bias inversion of a double well without residual particle excitation

, 2015
We design fast bias inversions of an asymmetric double well so that the lowest states in each well remain so and free from residual motional excitation.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Study of fission using multi-nucleon transfer reactions

EPJ Web of Conferences, 2017
It is shown that multi-nucleon transfer reaction is a powerful tool to study fission of exotic neutronrich actinide nuclei, which cannot be accessed by particle-capture or heavy-ion fusion reactions.

Dynamic formation of Rydberg aggregates at off-resonant excitation [PDF]

, 2013
The dynamics of a cloud of ultra-cold two-level atoms is studied at off-resonant laser driving to a Rydberg state. We find that resonant excitation channels lead to strongly peaked spatial correlations associated with the buildup of asymmetric excitation

Asymmetric Parametric Excitation Mechanism for Biped Robot

Journal of the Robotics Society of Japan, 2012
This research proposes a Asymmetry Parametric Excitation for a Biped Robot. In our research, we succeeded in developing an experimental parametric excited walking robot with counter weights and achieved the improvement of energy efficiency. However, the mechanism of this improvement has not been clarified. In this paper, we clarify the relation between

Reducing Influence of Hardware of Communication Station on Characteristics of Asymmetric Biconical Dipole Using Magneto-Dielectric Substrate on Finite-Size Metal Screen

East European Journal of Physics
Based on the approximate analytical solution previously obtained by the authors to the problem of excitation (radiation, scattering) of electromagnetic waves by an asymmetric biconical dipole with distributed surface impedance (constant and variable) in ...

Curvature-induced symmetry breaking in nonlinear Schrodinger models [PDF]

, 2000
We consider a curved chain of nonlinear oscillators and show that the interplay of curvature and nonlinearity leads to a symmetry breaking when an asymmetric stationary state becomes energetically more favorable than a symmetric stationary state. We show

Projectile excitation in strongly asymmetric ion-atom collisions [PDF]

Journal of Physics B: Atomic, Molecular and Optical Physics, 1988
In an ion-atom collision at velocity v such that v>>ZT, the nuclear charge of the target, the first Born approximation is expected to be valid. However, if at the same time ZP>>ZT, where ZP is the projectile nuclear charge, the first Born approximation is never valid at non-relativistic velocities since the projectile field cannot be regarded as a ...
