A note on equivalences between various mixing scales [PDF]
arXiv, 2022 In this note, we provide with a simple example to show a defect in the definition of the geometric mixing scale, and then introduce an improved scale, called as the strong geometric mixing scale. The main theorem in this note is the equivalence between geometric mixing scale, strong geometric mixing scale and functional mixing scale, in the sense of ...

Geometry of River Networks I: Scaling, Fluctuations, and Deviations [PDF]
, 2000 This article is the first in a series of three papers investigating the detailed geometry of river networks. Large-scale river networks mark an important class of two-dimensional branching networks, being not only of intrinsic interest but also a ...

A Fractal Perspective on Scale in Geography
ISPRS International Journal of Geo-Information, 2016 Scale is a fundamental concept that has attracted persistent attention in geography literature over the past several decades. However, it creates enormous confusion and frustration, particularly in the context of geographic information science, because ...

Optimization of the Sequence of Washing Reverse Osmosis Membranes Used for Seawater Desalination [PDF]
Chemical and Biochemical Engineering Quarterly, 2017 Seawater contains a number of organic and inorganic components that cause fouling of membranes when subjected to a process of reverse osmosis desalination. This fouling is one of the most important problems in the management of desalination plants, as it

A methodology to characterize the energy transfer and inter-scale transport of coherent structures using mode decomposition [PDF]
arXiv, 2021 A methodology is developed to quantify the transfer and transport of kinetic energy of specific scales associated with coherent structures. Coherent motions are characterized by the triple decomposition of a multi-scale flow and used to define mean, coherent, and random kinetic energy.

Effects of gauge theory based number scaling on geometry
, 2013 Effects of local availability of mathematics (LAM) and space time dependent number scaling on physics and, especially, geometry are described. LAM assumes separate mathematical systems as structures at each space time point.

Fluctuation Analysis of Human Electroencephalogram [PDF]
, 2001 The scaling behaviors of the human electroencephalogram (EEG) time series are studied using detrended fluctuation analysis. Two scaling regions are found in nearly every channel for all subjects examined. The scatter plot of the scaling exponents for all

Capturing and Characterizing Human Activities Using Building Locations in America
ISPRS International Journal of Geo-Information, 2019 Capturing and characterizing collective human activities in a geographic space have become much easier than ever before in the big era. In the past few decades it has been difficult to acquire the spatiotemporal information of human beings. Thanks to the

Characterization of G protein-coupled estrogen receptor (GPER) in breast epithelial proliferation and morphogenesis [PDF]
, 2012 Estrogen (17β-estradiol, E2) plays an important role in regulating an array of functions in both male and female reproductive physiology. In the mammary gland, E2-induced proliferation, ductal outgrowth and subsequent branching morphogenesis is required ...
