a new type of backbone robot is presented in this paper. the core idea is to use a cross shape mechanism with the principle of functioning of the scissors linkages, known as a pantograph. although this continuum arm acts quite similar to tendon-driven robot, this manipulator does not include any tendon in its structure. this design does not suffer from the weaknesses of the continuum design suc...

Clear first harmonic emissions of Saturn Kilometric Radiation are discovered during the Cassini Grand Finale orbits. Both ordinary (O) and extraordinary (X) mode fundamental accompanied by X harmonics observed. Analysis shows that frequency ratio between is 2.01 ± 0.08, display weaker intensities than fundamental, 30–40 dB for X-X (fundamental-harmonic) type 10–30 O-X harmonic. The intensity re...

We propose a novel approach to continuum modeling of the dynamics of crystal surfaces. Our model follows the evolution of an ensemble of step configurations, which are consistent with the macroscopic surface profile. Contrary to the usual approach where the continuum limit is achieved when typical surface features consist of many steps, our continuum limit is approached when the number of step ...

The Balitsky-Fadin-Kuraev-Lipatov (BFKL) evolution equation is known to be " unstable " with respect to fluctuations in gluon virtuality, transverse momentum and energy requiring to go beyond the leading order BFKL. Still, these instabil-ities point to fruitful improvements of our deep understanding of QCD. Recent applications to next-leading order and to saturation problems are outlined.
