A novel polarization-modulator-based complementary frequency shifter (PCFS) has been proposed and then used to implement the generation of a frequency-locked multicarrier with single- and dual-recirculating frequency shifting loops, respectively. The transfer functions and output properties of PCFS and PCFS-based multicarrier generator have been studied theoretically. Based on our simulation re...

This paper analyses non-regular |2|-graded geometries, and show that they share many of the properties of regular geometries – the existence of a unique normal Cartan connection encoding the structure, the harmonic curvature as obstruction to flatness of the geometry, the existence of the first two BGG splitting operators and of (in most cases) invariant prolongations for the standard Tractor b...

Most people think of graphene as a flat membrane and the quality of physics observation depends on the flatness of it. However defective or strained graphene can present interesting properties, especially to a chemist. For example, generating pores or voids in graphene, oxidizing and disrupting the conjugation, as in the case of nanoporous graphene oxide, can generate a material that is catalyt...

In this note we discuss in general how to test the implementation code of statistical tests, and then we treat in detail the case of the Kolmogorov-Smirnov test. It will be shown that some “obvious” expected properties, like the flatness distributions of p-values from repeating drawings from the same parent distribution, are not indeed reproduced even in absence of bugs in the code, due to eith...

Developing new media for magnetic storage exhibiting perpendicular anisotropy, instead of the current longitudinal media, is a matter of the utmost importance [1]. The final goal is to produce a nanopatterned media able to overcome the superparamagnetic limit (information is lost due to thermal fluctuations) at room temperature. In this work, it is shown that nitrogen irradiation of thin films ...

In the present study, the frontal and facial features of 112 populations from around the world are compared in terms of frontal and facial flatness measurements. Univariate analyses and canonical correlation analysis were applied to six indices representing flatness of frontal and facial bones. The deep infraglabellar notch, marked prognathism, and flat frontal bone show distinctive Australian/...

The effects of removing large scales external to the inertial range on the properties of scales within the inertial range are studied in a high-Reynolds-number turbulent flow. Structure functions of both even and odd orders are strongly affected across the entire inertial range, but odd-order moments are affected to a greater degree. In particular, the skewness of velocity increments shows a si...

A general theory is used to describe the correlation properties of polarization mode dispersion (PMD) in a birefringent, linear, dispersive medium such as optical fibers. The theory includes the effects of frequency dependence of birefringence on all orders, and it is capable of providing statistical information about secondand higher-order correlations among the polarization and PMD vectors. W...

The evolution of a universe with Brans-Dicke gravity and nonzero curvature is investigated here. We present the equations of motion and their solutions during the radiation dominated era. In a Friedman-Robertson-Walker cosmology we show explicitly that the three possible values of curvature κ = +1, 0,−1 divide the evolution of the Brans-Dicke universe into dynamically distinct classes just as f...
