Controlling effective dispersion within a channel with flow and active walls [PDF]
, 2019 Channels are fundamental building blocks from biophysics to soft robotics, often used to transport or separate solutes. As solute particles inevitably transverse between streamlines along the channel by molecular diffusion, the effective diffusion of the solute along the channel is enhanced - an effect known as Taylor dispersion.

Controlling the sign of chromatic dispersion in diffractive optics [PDF]
, 2017 Diffraction gratings disperse light in a rainbow of colors with the opposite order than refractive prisms, a phenomenon known as negative dispersion [1, 2].

A preliminary study on dispersions of fatigue properties of materials [PDF]
arXiv, 2016 Static mechanical properties (e.g. elastic modulus) and fatigue properties of a material all have dispersions. Material inhomogeneity (it can be characterized well by the dispersion of elastic modulus) is the internal factor of dispersions of fatigue properties and the dispersion of the load is the external factor.

Dispersion engineering and frequency comb generation in thin silicon nitride concentric microresonators [PDF]
Nature Communications, 2016 Kerr nonlinearity-based frequency combs and solitons have been generated from on-chip microresonators. The initiation of the combs requires global or local anomalous dispersion which leads to many limitations, such as material choice, film thickness, and

Diffraction-free and dispersion-free pulsed beam propagation in dispersive media [PDF]
, 2001 Pulsed Bessel beams of light propagating in free-space experience diffraction effects that resemble those of anomalous dispersion on pulse propagation. It is then shown that a pulsed Bessel beam in a normally dispersive material can remain diffraction- and dispersion-free due to mutual cancellation of diffraction and group velocity dispersion. The size

Dispersion measures and dispersive orderings [PDF]
Statistics & Probability Letters, 2003 In this paper, the comparison of random variables according to the functionals of a general class of dispersion measures is characterized in terms of the dilation order. The Gini's mean difference is a particular member of this general class. In addition, a new and weaker order, called the second-order absolute Lorenz ordering, is introduced, and we ...

Interspersions and Dispersions [PDF]
Proceedings of the American Mathematical Society, 1993 An array A = ( a i j ) A = ({a_{ij}}) of all the positive integers is an interspersion if the terms of any two rows, from some point on, alternate in size, and a dispersion if, for a suitable sequence (

Core-Periphery and Peripherality in Regional Science [PDF]
Prostranstvennaâ ÈkonomikaThe article presents an analytical review of the development of the core-periphery and peripherality concepts in economic theory. The stages of formation of the core-periphery approach are marked by the contributions of the school of Latin American ...

Dispersal of Epithelium-Associated Pseudomonas aeruginosa Biofilms
mSphere, 2020 Pseudomonas aeruginosa grows in highly antibiotic-tolerant biofilms during chronic airway infections. Dispersal of bacteria from biofilms may restore antibiotic susceptibility or improve host clearance.

Rodriguésia, 2014 This work analyses and describes fruit, seed and embryo morphology of 12 Dipterygeae species. The fruit is quite distinct among genera, being a legume in Taralea, a drupoid legume in Dipteryx and a cryptosamara in Pterodon. It was observed that the three
