多态反应是一类广泛存在于金属酶催化、光化学弛豫、电子转移等过程中的独特化学反应。准确描述多态反应中的态与态之间的转换过程，对理解阐释相关化学反应机制至关重要。通过定位极小能量交叉点(minimum energy crossing point,MECP)，可以从能量和结构的角度讨论态与态之间的转换过程。相比于难度高、计算代价昂贵的非绝热分子动力学等方法，直接优化MECP可以在不损失关键化学信息的前提...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On cancellation laws in cardinal arithmetic without the axiom of choice

Urban carsharing services provide flexible, affordable and green mobility options where customers can pick up a car from one station and return it to the same station (round trip) or any other station...
PARAMETER CHOICE FOR FAMILIES OF MAPS WITH MANY CRITICAL POINTS
PARAMETER CHOICE MAPS WITH MANY CRITICAL POINTS
2015/9/25
We consider families of smooth one-dimensional maps with several critical points and outline the main ideas of the construction in the parameter space that allows to get infinite Markov Partitions and...
On the Choice of Functional Form for Hedonic Price Functions
Hedonic Price Functions Choice
2015/9/18
this study examines how errors in measuring
marginal attribute prices vary with the form of the hedonic
price function. In simulations, consumers with known utility
functions bid for houses with ei...
Large-Scale Simultaneous Hypothesis Testing: The Choice of a Null Hypothesis
Null Hypothesis Simultaneous Hypothesis Testing
2015/8/20
Current scientific techniques in genomics and image processing routinely produce hypothesis testing problems with hundreds or thousands of cases to consider simultaneously.
This poses new di...
Induced Cylindric Algebras of Choice Structures
epsilon calculus canonical model monadic algebra sigma complete Boolean algebra
2011/9/5
Abstract: One of the benefit properties implied by the extensionality axiom of Hilbert's epsilon calculus is that the calculus becomes complete with respect to the choice structures as semantics. Anot...
Approximate group context tree: applications to dynamic programming and dynamic choice models

2011/9/29
Abstract: The paper considers a variable length Markov chain model associated with a group of stationary processes that share the same context tree but potentially different conditional probabilities....
Sharp Thresholds for Monotone Non Boolean Functions and Social Choice Theory
Non Boolean Functions Social Choice Theory
2010/11/22
A key fact in the theory of Boolean functions $f : \{0,1\}^n \to \{0,1\}$ is that they often undergo sharp thresholds. For example: if the function $f : \{0,1\}^n \to \{0,1\}$ is monotone and symmetr...
Reverse mathematics and equivalents of the axiom of choice
Reverse mathematics equivalents axiom of choice
2010/12/8
We study the reverse mathematics of countable analogues of several maximality principles that are equivalent to the axiom of choice in set theory.

Inner product space no ortho-normal basis without choice
2010/12/1
We prove in ZF that there is an inner product space, in fact, nicely definable with no orthonormal basis.
