many steps of seismic data processing sequence suppose that data sets are sampled in time and spatial dimensions uniformly. today, this assumption is true but only in time dimension. modern seismic exploration equipment permits seismic data sets to be sampled uniformly and densely in time dimension. however, along spatial dimension uniform and dense sampling are not possible because of operatin...

In this paper, we will study the asymptotic geometry of 4-dimensional steady gradient Ricci solitons under condition that they dimension reduce to 3-manifolds. We show such either strongly a spherical space form S3/Γ or weakly 3-dimensional Bryant soliton. also soliton singularity models with nonnegative curvature outside compact set are Ricci-flat ALE 4-manifolds manifolds. As further applicat...

An active area of public health policy in the United States is policy meant to promote healthy eating, reduce overconsumption of food, and prevent overweight/obesity. Public discussion of such obesity prevention policies includes intense ethical disagreement. We suggest that some ethical disagreements about obesity prevention policies can be seen as rooted in a common concern with equality or w...
