Multiwalled carbon nanotube (MWCNT) arrays have been directly synthesized from templated Fe2O3 nanoparticles on the C-face of 4H-SiC substrates by microwave plasma chemical vapor deposition (MPCVD), and the room-temperature thermal resistances of SiC-MWCNT-Ag interfaces at 69–345 kPa as well as the thermal resistances of SiCMWCNT-Ag interfaces up to 250 C (at 69 kPa) have been measured using a ...

Using an identity for effective resistances, we find a relationship between the arithmetic-geometric index and the global ciclicity index. Also, with the help of majorization, we find tight upper and lower bounds for the arithmetic-geometric index.

Given an electrical circuit each edge e of which is an isotropic conductor with a monomial conductivity function y∗ e = y r e/μ s e. In this formula, ye is the potential difference and y∗ e current in e, while μe is the resistance of e; furthermore, r and s are two strictly positive real parameters common for all edges. In particular, r = s = 1 correspond to the standard Ohm low. In 1987, Gvish...
