We performed the numerical simulation of quantum turbulence produced by thermal counterflow in superfluid He by using the vortex filament model. The pioneering work was made by Schwarz, which has two defects. One is neglecting non-local terms of the Biot-Savart integral (localized induction approximation, LIA), and the other is the unphysical mixing procedure in order to sustain the statistical...

The analytical expression of the on-axis field for an infinitely long helical undulator, derived in terms of undulator period length, uniform current density, inner radius and dimensions of the coils, was compared with numerical analyses of model undulators based on the Biot-Savart law. The two calculations agreed within 110. The expression also showed that the on-axis field has the first harm...

In this paper, we propose a hybrid microrobot concept to increase dynamic efficiency and adapt these systems for use in various working environments. The microrobot consists of a head capable of spiral motion, legs capable of paddling motion, and fish-like fins. We developed a prototype with a rotatable head and a body that has legs and fins. Additionally, we developed a control system and carr...

Fantasy proneness has recently been related to creative thinking. To try and explain this link, we examined whether the relation was mediated by Openness Experience (openness) because fantasy openness involve an imaginative thinking style. Study 1 assessed (Creative Experiences Questionnaire), openness, (divergent) in 87 undergraduates (77% women, mean age 21 years). 2 replicated method with mu...
