Research Progress and Prospect of High-Entropy Alloy Materials

open access: yes中国工程科学, 2023
With the rapid development of world’s technological level and the urgent demand of national economic construction for high-performance alloy materials, traditional single-component alloys gradually fail to satisfy the increasing service requirements ...

Spin Entropy

open access: yesEntropy, 2022
Two types of randomness are associated with a mixed quantum state: the uncertainty in the probability coefficients of the constituent pure states and the uncertainty in the value of each observable captured by the Born’s rule probabilities. Entropy is a quantification of randomness, and we propose a spin-entropy for the observables of spin pure states ...

Effect of serrated grain boundary on tensile and creep properties of a precipitation strengthened high entropy alloy

open access: yesScience and Technology of Advanced Materials, 2023
In this study, tensile and creep deformation of a high-entropy alloy processed by selective laser melting (SLM) has been investigated; hot ductility drop was identified at first, and the loss of ductility at elevated temperature was associated with ...

Non-Value-Added Tax to improve market fairness and quality

open access: yesFinancial Innovation, 2022
The promotion of both market fairness and efficiency has long been a goal of securities market regulators worldwide. Accelerated digital disruption and abusive trading behaviors, such as the GameStop mania, prompt regulatory changes.

Entropy of universe as entanglement entropy [PDF]

open access: yesPhysics Letters B, 2013
We note that the observable part of universe at a certain time t_P is necessarily limited, when there is a beginning of universe. We argue that an appropriate spacetime region associated with an observer from tI to t_P is the causal diamond which is the overlap of the past/future of the observer at t_P/t_I respectively.

Naive entropy of dynamical systems [PDF]

open access: yes, 2016
We study an invariant of dynamical systems called naive entropy, which is defined for both measurable and topological actions of any countable group.

Generalised exponential families and associated entropy functions

open access: yes, 2008
A generalised notion of exponential families is introduced. It is based on the variational principle, borrowed from statistical physics. It is shown that inequivalent generalised entropy functions lead to distinct generalised exponential families.
