Transform-domain adaptive lters refer to LMS lters whose inputs are preprocessed with a unitary data-independent transformation followed by a power normalization stage. The transformation is typically chosen to be the discrete Fourier transform (DFT), although other transformations such as the cosine transform (DCT), the Hartley transform (DHT), or the Walsh-Hadamard transform, have also been p...

Horizontal behavior of highly migratory marine species is difficult to decipher because animals are wide-ranging, spend minimal time at the ocean surface, and utilize remote habitats. Satellite telemetry enables researchers to track individual movements, but population level inferences are rare due to data limitations that result from difficulty of capture and sporadic tag reporting. We introdu...

This paper proposes a parametric implementation of the Hansen and Jagan-nathan (1991) volatility bounds based on log-normal distributions. We obtain analytical expressions for the bounds as well as stochastic discount factors. Using this framework we analyze the role of preferences in determining risk premia. We show that neither risk aversion nor in general determine the elasticity of intertem...

The aim of this paper is to present the application of the analytical series technique to study properties of the nonlinear chaotic dynamical systems. More specifically, Laplace–Adomian decomposition method is applied to Rössler system and the so-called generalized Lorenz system. Some advantages and possible applications of this approach are discussed. Results are illustrated by numerical compu...

Analyses of observable supernova neutrino oscillation effects require the calculation of the electron (anti)neutrino survival probability Pee along a given supernova matter density profile. We propose a simple analytical prescription for Pee, based on a double-exponential form for the crossing probability and on the concept of maximum violation of adiabaticity. In the case of two-flavor transit...

The cosmic microwave background (CMB) temperature autocorrelations, induced by a magnetized adiabatic mode of curvature inhomogeneities, are computed with semianalytical methods. As suggested by the latest CMB data, a nearly scale-invariant spectrum for the adiabatic mode is consistently assumed. In this situation, the effects of a fully inhomogeneous magnetic field are scrutinized and constrai...

We present a novel approach for Lip synchronization by analyzing the relationship between a person’s speech signal and data extracted from his/her lip movements. To model the speech we use a nonlinear-time-varying sum of AM-FM signals each of which models a single formant frequency. The model is then realized using Taylor series expansions such that a closed form formula is achieved which shows...

We report on an accurate closed-form analytical model for the gain of a Brillouin fiber amplifier that accounts for material loss in the depleted pump regime. We determined the operational model limits with respect to its relevant parameters and pump regimes through both numerical and experimental validation. As such, our results enable accurate performance prediction of Brillouin fiber amplifi...

We develop an analytical formalism that is suitable for studying inhomogeneous structure formation, by studying the joint statistics of dark matter halos forming at two points. Extending the Bond et al. (1991) derivation of the mass function of virialized halos, based on excursion sets, we derive an approximate analytical expression for the “bivariate” mass function of halos forming at two reds...
