Power frequency interference and suppression in measurement of power transmission tower grounding resistance

“If you want peace, work for justice.” – Pope Paul VI This paper explores how the children’s right to be heard is implemented in the criminal proceedings in Romania and Norway. The judicial practices in the two countries are analysed in relation to four elements identified in the literature as relevant to the child’s right to be heard- space, voice, audience and influence. The two juvenile justice systems are then compared to each other, as well as to international best practices, with the final aim of identifying small-scale measures worth disseminating in Romania and Norway to strengthen the effectiveness of child’s right to be heard. The paper argues that a more effective implementation of the children’s right to be heard strengthen all the array of the children’s rights, makes the juvenile justice system more child-friendly and facilitates the transition from conflict and punitive justice towards positive peace. Keywords: right of the child to be heard, juvenile justice, children’s rights, child-friendly justic

High-order harmonic generations in tilted Weyl semimetals

We investigate high-order harmonic generations (HHGs) under the comparison of Weyl cones in two types. Due to the hyperboloidal electron pocket structure, strong noncentrosymmetrical generations in high orders are observed around a single type-II Weyl point, especially at frequency zero. Such remarkable DC signal is proved to have attributions from the intraband transition after spectral decomposition. Under weak pulse electric field , the linear optical response of a non-tilted Weyl cone is consistent with the Kubo theory. With more numerical simulations, we conclude the non-zero chemical potential can enhance the even-order generations, from the slightly tilted system to the over-tilted systems. In consideration of dynamical symmetries, type-I and -II Weyl cones also show different selective responses under the circularly polarized light. Finally, using a more realistic model containing two pairs of Weyl points, we demonstrate the paired Weyl points with opposite chirality could suppress the overall even-order generations

Weyl points and topological nodal superfluids in a face-centered cubic optical lattice

We point out that a face-centered cubic (FCC) optical lattice, which can be realised by a simple scheme using three lasers, provides one a highly controllable platform for creating Weyl points and topological nodal superfluids in ultracold atoms. In non-interacting systems, Weyl points automatically arise in the Floquet band structure when shaking such FCC lattices, and sophisticated design of the tunnelling is not required. More interestingly, in the presence of attractive interaction between two hyperfine spin states, which experience the same shaken FCC lattice, a three-dimensional topological nodal superfluid emerges, and Weyl points show up as the gapless points in the quasiparticle spectrum. One could either create a double Weyl point of charge 2, or split it to two Weyl points of charge 1, which can be moved in the momentum space by tuning the interactions. Correspondingly, the Fermi arcs at the surface may be linked with each other or separated as individual ones.Comment: 5 pages, 2 figures in the main text; 2 pages, 2 figures in the supplemental materia
