Numerical Analyses of Weakly Nonlinear Velocity-Density Coupling [PDF]
, 2001 We study evolution of various statistical quantities of smoothed cosmic density and velocity fields using N-body simulations. The parameter $C\equiv /( )$ characterizes nonlinear coupling of these two fields and determines behavior of bulk velocity ...

A general smoothing inequality for disordered polymers [PDF]
, 2013 This note sharpens the smoothing inequality of Giacomin and Toninelli for disordered polymers. This inequality is shown to be valid for any disorder distribution with locally finite exponential moments, and to provide an asymptotically sharp constant for

An improved method using adaptive smoothing for GNSS tomographic imaging of ionosphere.
PLoS ONE, 2021 Global navigation satellite system (GNSS) is a well-established sensors in the recent ionosphere research. By comparing with classical meteorological equipments, the GNSS application can obtain more reliable and precious ionospheric total electron ...

Partial smoothness and constant rank
, 2018 The idea of partial smoothness in optimization blends certain smooth and nonsmooth properties of feasible regions and objective functions. As a consequence, the standard first-order conditions guarantee that diverse iterative algorithms (and post-optimality analyses) identify active structure or constraints. However, by instead focusing directly on the

A Fast Two-Stage Bilateral Filter Using Constant Time O(1) Histogram Generation
Sensors, 2022 Bilateral Filtering (BF) is an effective edge-preserving smoothing technique in image processing. However, an inherent problem of BF for image denoising is that it is challenging to differentiate image noise and details with the range kernel, thus often ...

Constructing Reference Metrics on Multicube Representations of Arbitrary Manifolds [PDF]
, 2016 Reference metrics are used to define the differential structure on multicube representations of manifolds, i.e., they provide a simple and practical way to define what it means globally for tensor fields and their derivatives to be continuous. This paper
