“…Recently, the atmospheric pressure dielectric barrier discharge (APDBD) for annealing thin wire has become greatly interesting [21,30]. Also, our previous studies showed that annealing using APDBD is possible for thin copper wire [31]. However, the generated temperature by ion bombarding was not estimated.…”

“…However, this method has some drawbacks: low efficiency due to the division of the annealing and cleaning processes and environmentally harmful because of using chemical to clean thin wire, for example, Tri-chloethane, it is hazardous to human body and has ozone layer effect. The new annealing system in which the annealing and cleaning processes are simultaneously operated in Atmospheric Pressure DielectricBarrier Discharge (APDBD) [5][6][7][8][9] is the potential solution for these drawbacks. In previous studied, it is shown that wire annealing [10,11] and cleaning [12] using APDBD is totally possible.…”

“…Also, our previous studies showed that annealing using APDBD were possible for thin copper wire. 12) However, the ion bombarding energy in APDBD has not been simulated. In this study, we propose an analysis model using helium gas and low-frequency (35-45 kHz) applied voltage to analyze the annealing temperature in APDBD.…”

In contrast to scalar and tensor modes, vector modes of linear perturbations around an expanding Friedmann-Robertson-Walker universe decay. This makes them largely irrelevant for late time cosmology, assuming that all modes started out at a similar magnitude at some early stage. By now, however, bouncing models are frequently considered which exhibit a collapsing phase. Before this phase reaches a minimum size and re-expands, vector modes grow. Such modes are thus relevant for the bounce and may even signal the breakdown of perturbation theory if the growth is too strong. Here, a gauge-invariant formulation of vector mode perturbations in Hamiltonian cosmology is presented. This lays out a framework for studying possible canonical quantum gravity effects, such as those of loop quantum gravity, at an effective level. As an explicit example, typical quantum corrections, namely those coming from inverse densitized triad components and holonomies, are shown to increase the growth rate of vector perturbations in the contracting phase, but only slightly. Effects at the bounce of the background geometry can, however, be much stronger.
