Frequency-Dependent Schroeder Allpass Filters

open access: yesApplied Sciences, 2019
Since the introduction of feedforward−feedback comb allpass filters by Schroeder and Logan, its popularity has not diminished due to its computational efficiency and versatile applicability in artificial reverberation, decorrelation, and dispersive

Directional supercontinuum generation: the role of the soliton

open access: yes, 2019
In this paper we numerically study supercontinuum generation by pumping a silicon nitride waveguide, with two zero-dispersion wavelengths, with femtosecond pulses.

Dispersion-Corrected Mean-Field Electronic Structure Methods.

open access: yesChemical Reviews, 2016
Mean-field electronic structure methods like Hartree-Fock, semilocal density functional approximations, or semiempirical molecular orbital (MO) theories do not account for long-range electron correlation (London dispersion interaction).

Survey on Drosophila suzukii Natural Short-Term Dispersal Capacities Using the Mark−Release−Recapture Technique

open access: yesInsects, 2019
Spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), has become a key pest for soft fruits and cherries in Europe in less than a decade since the first outbreak in 2007.

Study of the combined radial post-feeding dispersion of the blowflies Chrysomya megacephala (Fabricius) and C. albiceps (Wiedemann) (Diptera, Calliphoridae) Estudo da dispersão radial combinada de Chrysomya megacephala (Fabricius) e C. albiceps (Wiedemann) (Diptera, Calliphoridae)

open access: yesRevista Brasileira de Entomologia, 2005
Blowflies use discrete and ephemeral substrates to feed their larvae. After they run out of food, the larvae begin to disperse in order to find adequate places for pupation or additional food sources, a process named post-feeding larval dispersion.

Relative dispersion analysis of GLAD surface drifters in the Gulf of Mexico [PDF]

open access: yes, 2016
Relative dispersion analysis of the Lagrangian dataset derived from the GLAD drifter campaign in the Gulf of Mexico was computed on pairs derived from actual triplets.

Improved estimators for dispersion models with dispersion covariates

open access: yes, 2010
In this paper we discuss improved estimators for the regression and the dispersion parameters in an extended class of dispersion models (J{\o}rgensen, 1996).

Quantum theory of dispersive electromagnetic modes [PDF]

open access: yes, 1998
A quantum theory of dispersion for an inhomogeneous solid is obtained, from a starting point of multipolar coupled atoms interacting with an electromagnetic field.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...
