Cascaded second-order nonlinear effects attract great interest because of their potential use in devices that require nonlinear (NL) phase shifts. – 9 It is only recently that the case of x s2d distributed couplers in the cascading regime has been considered. The nonlinear effect studied in Ref. 10 is second-harmonic generation, for which only the fundamental frequency field (at v) is incident ...

The robot platooning problem has been studied extensively by the robotics community under some assumptions such as communication existance and global full observability. In this paper, we consider the platooning problem where the previous assumptions are not valid. In such a context, platooning can be considered as a specific flocking which is a collective decision model. This model can, thus, ...

The optical second-harmonic generation from a thin crystalline film on a substrate is theoretically investigated for both s and p polarized incident light. The contributions of lattice misfit strain as well as of misfit dislocation strain to the second-order nonlinear optical susceptibility are described using a nonlinear photoelastic tensor and can be separated by a polarization analysis of th...

The measurement of the Higgs quartic coupling modifier between a boson pair and vector pair, ?2V, is expected to be achieved from vector-boson fusion (VBF) production pair. However, this process involves another unmeasured parameter, trilinear self-coupling ??. A sensitivity analysis should target both parameters. Since LHC cannot avoid gluon pollution, which becomes severe for non-SM ??, an el...

Retro-reaction of radical monoadducts of a paramagnetic endohedral metallofullerene, La@C(2v)-C(82), is shown using thermal reaction in the presence of a radical trapping reagent, affording pristine La@C(2v)-C(82) in high yield (96%).

We report on evanescently coupled Ge waveguide photodetectors that are grown on top of Si rib waveguides. A Ge waveguide detector with a width of 7.4mum and length of 50 mum demonstrated an optical bandwidth of 31.3 GHz at -2V for 1550nm. In addition, a responsivity of 0.89 A/W at 1550 nm and dark current of 169 nA were measured from this detector at -2V. A higher responsivity of 1.16 A/W was a...

Three groups F ⊆ T ⊆ V , known as Thompson groups, have generated interest since R. J. Thompson introduced them in the late 1960s. Part of their initial interest was the fact that T and V supplied the first known examples of infinite, simple, finitely presented groups. Since then, other properties of the groups have been studied as well as their interaction with other areas of mathematics. The ...

In [2] we introduce groups nV and n̂V for integers n ≥ 1 and also ωV and ω̂V where ω represents the natural numbers. These are all subgroups of the homeomorphism group of the Cantor set. The group 1V is a group known as the Thompson group V which is infinite, simple and finitely presented (see [6]). In [2], we show that 2V is infinite, simple and finitely generated and that it is not isomorphic t...
