Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Almost sure scattering for the cubic NLS on R3T1
R3T1 三次NLS 散射 Cauchy问题
2023/5/18
We consider the Cauchy problem for the defocusing cubic NLS on R3T1 and establish almost sure scattering for random initial data. The main obstacle to extend the classical almost sure scattering resul...
"Make Sure DSA Signing Exponentiations Really are Constant-Time''
applied cryptography digital signatures side-channel analysis
2016/6/8
TLS and SSH are two of the most commonly used protocols for securing Internet traffic. Many of the implementations of these protocols rely on the cryptographic primitives provided in the OpenSSL libra...
Phosphine as a superconductor?Sure,but the story may be complicated
Phosphine superconductor story complicated
2016/2/23
Phosphine is one of the newest materials to be named a superconductor, a material through which electricity can flow with zero resistance.In 2015, scientists reported that they had liquefied the chemi...
Marginal empirical likelihood and sure independence screening
Empirical likelihood high dimensional data analysis independence sure screening large deviation
2016/1/25
We study a marginal empirical likelihood approach in scenarios when the num-ber of variables grows exponentially with the sample size. The marginal empirical likelihood ratios as functions of the para...

We study a marginal empirical likelihood approach in scenarios when the num-ber of variables grows exponentially with the sample size. The marginal empirical likelihood ratios as functions of the para...
A simpler axiomatization of the Shelah-Spencer almost sure theories
Shelah-Spencer almost sure theories
2015/9/28
We give an explicit AE-axiomatization of the almost sure theories
of sparse random graphs G(n, n−α) of Shelah-Spencer. In the process
we give a method of constructing extensions of graphs whos...
Are You Sure That This Happened? Assessing the Factuality Degree of Events in Text
Factuality Degree Happened
2015/9/10
Identifying the veracity, or factuality, of event mentions in text is fundamental for reasoning
about eventualities in discourse. Inferences derived from events judged as not having happened,
or as ...

Teenagers The media Mark Picture Oil Acrylic resin Sculpture, painting
2014/11/18
Personal mythology perceived through adolescent desire, and quotidian events inform my work. Through a variety of media, I explore themes of mark making, identity and environment. By dissecting and re...
Conditional Sure Independence Screening
False selection rate Generalized linear models Sparsity Sure screening Variable selection
2012/6/21
Independence screening is a powerful method for variable selection for `Big Data' when the number of variables is massive. Commonly used independence screening methods are based on marginal correlatio...
From almost sure local regularity to almost sure Hausdorff dimension for Gaussian fields
Gaussian processes Hausdorff dimension (multi)fractional Brownian motion multiparameter processes Holder regularity stationarity
2012/6/19
Fine regularity of stochastic processes is usually measured in a local way by local H\"older exponents and in a global way by fractal dimensions. Following a previous work of Adler, we connect these t...
A Quasi-Sure Approach to the Control of Non-Markovian Stochastic Differential Equations
Stochastic optimal control non-Markovian SDE second order BSDE G-expectation random G-expectation volatility uncertainty risk measure
2011/7/5
We study stochastic differential equations (SDEs) whose drift and
diffusion coefficients are path-dependent and controlled. We construct
a value process on the canonical path space, considered simul...
Almost sure convergence and asymptotical normality of a generalization of Kesten's stochastic approximation algorithm for multidimensional case
Kesten's stochastic approximation algorithm multidimensional
2011/6/20
It is shown the almost sure convergence and asymptotical normality of a generalization of
Kesten's stochastic approximation algorithm for multidimensional case.
In this generalization, the step incr...
The almost sure behavior of certain spatial repartitions of local empirical processes indexed by functions
Empirical process, Functional limit theorems Poisson processes
2011/7/5
We investigate a particular form of weak convergence of the local empirical process.
A sharp correlation inequality with an application to almost sure local limit theorem
Correlation inequality i.i.d. random variables lattice distributed
2011/2/21
We prove a new sharp correlation inequality for sums of i.i.d.square integrable lattice distributed random variables. We also apply it to establish an almost sure local limit theorem for iid square in...
