Vulnerability Assessment and Spatio-Temporal Dynamics Analysis of Agricultural Flood in China

open access: yesFrontiers in Environmental Science, 2022
Flood is one of the main problems faced by agricultural production in China. The research of agriculture’s floods vulnerability is the premise of scientifically dealing with floods. Based on the vulnerability assessment framework of “sensitivity-exposure-

Entropy production in quantum Yang-Mills mechanics in semi-classical approximation [PDF]

open access: yes, 2015
We discuss thermalization of isolated quantum systems by using the Husimi-Wehrl entropy evaluated in the semiclassical treatment. The Husimi-Wehrl entropy is the Wehrl entropy obtained by using the Husimi function for the phase space distribution.

Maximum quantum entropy method [PDF]

open access: yesPhysical Review B, 2018
Maximum entropy method for analytic continuation is extended by introducing quantum relative entropy. This new method is formulated in terms of matrix-valued functions and therefore invariant under arbitrary unitary transformation of input matrix. As a result, the continuation of off-diagonal elements becomes straightforward.

A Relationship between the Ordinary Maximum Entropy Method and the Method of Maximum Entropy in the Mean [PDF]

open access: yesEntropy, 2014
There are two entropy-based methods to deal with linear inverse problems, which we shall call the ordinary method of maximum entropy (OME) and the method of maximum entropy in the mean (MEM). Not only doesMEM use OME as a stepping stone, it also allows for greater generality.

Lorenz Curve-Based Entropy Thresholding on Circular Histogram

open access: yesIEEE Access, 2020
Circular histogram thresholding is a new threshold selection method in color image segmentation. However, the method of the existing circular histogram thresholding based on the Otsu Criteria lacks the generality of using the circular histogram. In order

Entropy for gravitational Chern-Simons terms by squashed cone method [PDF]

open access: yes, 2015
In this paper we investigate the entropy of gravitational Chern-Simons terms for the horizon with non-vanishing extrinsic curvatures, or the holographic entanglement entropy for arbitrary entangling surface.
