Sectorial retinitis pigmentosa (RP) and optic disc pit (ODP) are rare clinical conditions. We present a 40-year-old woman with a history of mild night blindness and decreased vision in the right eye for about 5 years. Fundus examination revealed retinal pigmentary changes in the superior and inferotemporal sectors covering the macula and reduced arterial calibre and ODP at the temporal edge of ...

This article examines the determinants of private investment in Brazil from sectorial industry data for the period of 1996 to 2010. The series of gross fixed capital formation, commonly used in empirical studies of aggregate investment, eliminates irregular adjustments of individual production units due to the aggregation process. Using the industry’s sectorial data it is possible to avoid smoo...

The recent economic crisis that lasted between 2007 and 2009 was predetermined not only by the presence of “bubbles” in financial sector, but also allometric character sectorial development. This structural imbalance, which accumulated over years, result a lack conjugation new technological platform, forms methods management practices social It can be expected breakthrough will bring with it “r...

We consider a signal restoration from observations corrupted by random noise. The local maximum likelihood technique allows to deal with quite general statistical models of signal dependent observations, relaxes the standard parametric modelling of the standard maximum likelihood, and results in ßexible nonparametric regression estimation of the signal. We deal with the anisotropy of the signal...

We develop a very general operator-valued functional calculus for operators with an H∞−calculus.We then apply this to the joint functional calculus of two sectorial operators when one has an H∞calculus. Using this we prove theorem of Dore-Venni type on sums of sectorial operators and apply our results to the problem of Lp−maximal regularity. Our main assumption is the R-boundedness of certain s...

A closed-form solution is presented for a cantilevered sectorial plate subjected to a tip concentrated force. Since the particular solution for this problem was not found in the literature, it is derived here. Deflections from the total solution (particular plus homogeneous solutions) are compared to those from a finite element analysis and are found to be in excellent agreement, producing an e...

We report on the experimental observation of corner surface solitons localized at the edges joining planar interfaces of hexagonal waveguide array with uniform nonlinear medium. The face angle between these interfaces has a strong impact on the threshold of soliton excitation as well as on the light energy drift and diffraction spreading.
