Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：A New Joint Modeling Approach for Recurrent Event Data with Informative Terminal Event
信息性 终端事件 递归事件 数据联合 建模方法

In this article, we propose a new joint modeling approach for recurrent event data with informative terminal event via a gamma frailty by assigning a new type of double exponential Cox mod...
CENTRAL LIMIT THEOREM FOR RECURRENT RANDOM WALKS ON A STRIP WITH BOUNDED POTENTIAL
RANDOM WALKS CENTRAL LIMIT THEOREM
2015/9/29
We prove that a recurrent random walk (RW) in i.i.d. random
environment (RE) on a strip which does not obey the Sinai law exhibits the
Central Limit asymptotic behaviour.
SCALING LIMITS OF RECURRENT EXCITED RANDOM WALKS ON INTEGERS
Limit random walk RECURRENT EXCITED
2015/9/29
We describe scaling limits of recurrent excited random walks (ERWs) on
Z in i.i.d. cookie environments with a bounded number of cookies per site. We allow
both positive and negative excitations.
Central Limit Theorem for Excited Random Walk in the Recurrent Regime
Recurrent Regime Excited Random Walk
2015/9/29
We consider excited random walk on a strip. We assume that the
cookies are positive and that the total expected drift per site is less than 1/L where
L is the width of the strip. We prove a quenched...
We introduce the notion of recurrent geodesic rays in
a complete °at Lorentz 3-manifold. We completely classify the
dynamical behavior of geodesics in cyclic quotients, and apply this
classiˉcation...

A cross-shelf, water-column mass balance of radon-222 (222Rn) provided estimates of submarine groundwater discharge (SGD), which were then used to quantify benthic nutrient fluxes. Surface water and g...

A cross-shelf, water-column mass balance of radon-222 (222Rn) provided estimates of submarine groundwater discharge (SGD), which were then used to quantify benthic nutrient fluxes. Surface water and g...
Decorrelation by recurrent inhibition in randomly and strongly coupled networks
recurrent inhibition decorrelation Neurons and Cognition
2011/10/8
Abstract: I calculate the mean pairwise correlation between neurons in a network model characterized by strong and random interactions. The mean is calculated with respect to both temporal fluctuation...
The Simple Random Walk Snake on Z^4 is Recurrent
Simple Random Walk Snake Recurrent Probability
2011/8/26
Abstract: Consider the branching simple random walk on Z^d indexed by a critical geometric Galton-Watson tree conditioned to survive. Using the concept of unimodular random graphs, we show that the wa...
Recurrent host mobility in spatial epidemics: beyond reaction-diffusion
beyond reaction-diffusion spatial epidemics
2011/9/2
Human mobility is a key factor in spatial disease dynamics and related phenomena. In computational models host mobility is typically modeled by diffusion in space or onmetapolulation networks. Alterna...

Complex space form CR submanifold of maximal CR dimension
2011/2/28
Let M be a CR submanifold of maximal CR dimension of a complex space form M. The shape operator A of the distinguished vector field is recurrent if there exists a 1-form v such that ∇A = A X...
Effect of the duration of the synaptic activity on a delayed recurrent neuronal loop
Effect of the duration synaptic activity delayed recurrent neuronal loop
2010/11/10
A recurrent loop consisting of a single neuron is considered which is influenced by a chemical excitatory delayed synaptic feedback. We show the response of the system is dependent to the duration of ...
Dynamo generated field emergence through recurrent plasmoid ejections
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Magnetic buoyancy is believed to drive the transport of magnetic flux tubes from the convection zone to the surface of the Sun. The magnetic fields form twisted loop-like structures in the solar atmos...
Input-Dependent Suppression of Chaos in Recurrent Neural Networks
Chaos Recurrent Neural Networks
2010/4/7
Neuronal activity arises from an interaction between ongoing firing generated spontaneously by neural circuits and responses driven by external stimuli. Using mean-field analysis, we ask how a neural ...
