Spectrum-sliced wavelength division multiplexed systems with optical preamplifiers [PDF]
, 2009 The effect of dispersion on a spectrum-sliced wavelength division multi-plexed system with an optical preamplifier receiver is investigated using a theoretical model based on the statistics to improve understanding of spectrum slicing in a realistic ...

Early warning signs for SPDEs with continuous spectrum
European Journal of Applied MathematicsIn this work, we study early warning signs for stochastic partial differential equations (SPDEs), where the linearisation around a steady state is characterised by continuous spectrum. The studied warning sign takes the form of qualitative changes in the

Monitoring continuous spectrum observables: the strong measurement limit
SciPost Physics, 2018 We revisit aspects of monitoring observables with continuous spectrum in a quantum system subject to dissipative (Lindbladian) or conservative (Hamiltonian) evolutions.

Retrieving wind statistics from average spectrum of continuous-wave lidar [PDF]
Atmospheric Measurement Techniques, 2013 The aim of this study is to experimentally demonstrate that the time-average Doppler spectrum of a continuous-wave (cw) lidar is proportional to the probability density function of the line-of-sight velocities. This would open the possibility of using

PhotonicsThe current research on light transmission under rainfall conditions primarily focuses on monochromatic converging light sources, and the related conclusions cannot be directly applied to spherical continuous-spectrum light sources (SCLSs).

CONTINUOUS SPECTRA RESTORATION BY AN ADAPTIVE WAY OF COMPUTING EXPERIMENTS WITH REGULARIZATION [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2013 The article deals with inverse spectroscopy problem - restoration of continuous spectra by mathematical treatment of measured spectra, distorted by the spectrometer instrument function and noises.

Finite eigenfuction approximations for continuous spectrum operators
International Journal of Mathematics and Mathematical Sciences, 1993 In this paper, we introduce a new formulation of the theory of continuous spectrum eigenfunction expansions for self-adjoint operators and analyze the question of when operators may be approximated in an operator norm by finite sums of multiples of ...

About the continuous spectrum of vibrations of beam construction elements under high-frequency effects [PDF]
Инженерно-строительный журнал, 2012 In this paper the high-frequency vibrations of beam structural elements on the example of cantilever rod are analyzed. The purpose of this article is to show the existence of the boundary frequency, above which the structure behaves as a system with a ...

Weighted integral Hankel operators with continuous spectrum
Concrete Operators, 2017 Using the Kato-Rosenblum theorem, we describe the absolutely continuous spectrum of a class of weighted integral Hankel operators in L2(ℝ+). These self-adjoint operators generalise the explicitly diagonalisable operator with the integral kernel sαtα(s ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
