Good Dispersion, Bad Dispersion [PDF]
, 2019 Dispersion in marginal revenue products of inputs across plants is commonly thought to reflect misallocation, i.e., dispersion is "bad." We document that most dispersion occurs across plants within rather than between firms. In a model of multi-plant firms, we then show that dispersion can be "good": Eliminating frictions increases productivity ...

Dispersion in Fractures With Ramified Dissolution Patterns
Frontiers in Physics, 2018 The injection of a reactive fluid into an open fracture may modify the fracture surface locally and create a ramified structure around the injection point.

Dispersion-Corrected Mean-Field Electronic Structure Methods.
Chemical 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).

Metals, 2018 The exceptional potential of the graphene has not been yet fully translated into the Al matrix to achieve high-performance Al nanocomposite. This is due to some critical issues faced by graphene during its processing such as the dispersion uniformity ...

Ventilation and Air Quality in City Blocks Using Large-Eddy Simulation—Urban Planning Perspective
Atmosphere, 2018 Buildings and vegetation alter the wind and pollutant transport in urban environments. This comparative study investigates the role of orientation and shape of perimeter blocks on the dispersion and ventilation of traffic-related air pollutants, and the ...

Simulating Lagrangian Subgrid‐Scale Dispersion on Neutral Surfaces in the Ocean
Journal of Advances in Modeling Earth Systems, 2022 To capture the effects of mesoscale turbulent eddies, coarse‐resolution Eulerian ocean models resort to tracer diffusion parameterizations. Likewise, the effect of eddy dispersion needs to be parameterized when computing Lagrangian pathways using coarse ...

Realizing normal group-velocity dispersion in free space via angular dispersion [PDF]
, 2021 It has long been thought that normal group-velocity dispersion (GVD) cannot be produced in free space via angular dispersion. Indeed, conventional diffractive or dispersive components such as gratings or prisms produce only anomalous GVD. We identify the conditions that must be fulfilled by the angular dispersion introduced into a plane-wave pulse to ...

General relationships between consumer dispersal, resource dispersal and metacommunity diversity [PDF]
Ecol. Lett. 17, 175--184 (2014), 2014 One of the central questions of metacommunity theory is how dispersal of organisms affects species diversity. Here we show that the diversity-dispersal relationship should not be studied in isolation of other abiotic and biotic flows in the metacommunity.

Solitons in media with mixed, high-order dispersion and cubic nonlinearity [PDF]
, 2022 Although most soliton research has traditionally considered dominant quadratic dispersion, the recent discovery of pure-quartic solitons has inspired analysis of soliton solutions with large higher orders of dispersion. Here we present analytic expressions for families of bright soliton solutions at arbitrary dispersion orders and practical methods to ...

The Lagrangian particle dispersion model FLEXPART version 10.4
Geoscientific Model Development, 2017 Following its release and corresponding publication in GMD, we present the Lagrangian model FLEXPART 10.4, which simulates the transport, diffusion, dry and wet deposition, radioactive decay and first order chemical reactions of atmospheric tracers ...
