Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Occupation fields for Markov loops
马尔可夫循环 占用域 格林函数
2023/11/29
In this talk, we introduce occupation fields for vertices and oriented edges and compute their distributions. More precisely, under the Markov loop measure, the expected number for crossings of an ori...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Large deviations in random interlacements I: Large deviation principle of occupation measures
随机交错 大偏差 占用措施 大偏差原则
2023/5/10
In this lecture, I will talk about the large deviation problems in random interlacements, in particular the LDP of the occupation measure, and discuss its relations to sharp asymptotic probabilities o...
EXCURSIONS AND OCCUPATION TIMES OF CRITICAL EXCITED RANDOM WALKS
EXCURSIONS AND OCCUPATION TIMES EXCITED RANDOM WALKS
2015/9/29
We consider excited random walks (ERWs) on integers in i.i.d. environments with a bounded number of excitations per site. The emphasis is primarily on
the critical case for the transition between rec...
The halo occupation distribution (HOD) describes the bias between galaxies and dark matter by specifying (1) the probability P(N|M) that a halo of virial mass M contains N galaxies of a particular cla...
Theoretical models of the halo occupation distribution: Separating central and satellite galaxies
formation halos
2014/12/24
The halo occupation distribution (HOD) describes the relation between galaxies and dark matter at the level of individual dark matter halos. The properties of galaxies residing at the centers of halos...
Highest altitude ice age human occupation documented in Peruvian Andes（图）

2014/12/1
the southern Peruvian Andes, an archaeological team led by researchers at the University of Maine has documented the highest altitude ice age human occupation anywhere in the world — nearly 4,500 mete...
GEODESIGN INFORMATION MANAGEMENT AND PARAMETRIC MODELING OF TERRITORIAL OCCUPATION: NEW PARADIGMS AND CHALLENGES IN TERRITORIAL REPRESENTATION
Geoprocessing 3D Modeling Geodesign Urban Planning
2014/4/24
This paper intends to be a brief contextualization about the state-of-the-art on the use of Geoprocessing on urban planning in order to
present new paradigms and challenges on the use of geotecnolog...
Occupation times of spectrally negative Lévy processes with applications
Occupation time spectrally negative Lévy processes fluctuation theory scale functions
2011/2/21
In this paper, we compute the Laplace transform of occupation times (of the negative half-line) of spectrally negative Lévy processes. Our results are extensions of known results
for standard Brownia...
The Spatial Clustering of ROSAT All-Sky Survey AGNs II. Halo Occupation Distribution Modeling of the Cross Correlation Function
The Spatial Clustering ROSAT All-Sky Survey AGNs II
2011/1/11
This is the second paper of a series that reports on our investigation of the clustering properties of AGNs in the ROSAT All-Sky Survey (RASS) through cross-correlation functions (CCFs) with Sloan Dig...
Orbital occupation and magnetic moments of tetrahedrally coordinated iron in CaBaFe4O7
Orbital occupation magnetic moments tetrahedrally coordinated iron
2010/11/25
CaBaFe4O7 is a mixed-valent transition metal oxide having both Fe2+ and Fe3+ ions in tetrahedral coordination. Here we characterize its magnetic properties by magnetization measurements and investigat...
Time-dependent occupation numbers in reduced-density-matrix functional theory: Correlation-induced oscillations
Time-dependent occupation numbers reduced-density-matrix functional theory
2010/11/18
We prove that if the two-body terms in the equation of motion for the one-body reduced density
matrix are approximated at each instant of time from ground-state functionals, the eigenvalues of the on...
Constraining halo occupation properties of X-ray AGNs using clustering of Chandra sources in the Bootes survey region
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We present the most precise measurement to date of the spatial clustering of X-ray selected AGNs using a sample derived from the Chandra X-ray Observatory survey in the Bootes field. The real-space tw...
Occupation and Local Times for Skew Brownian Motion with Applications to Dispersion Across an Interface
Skew Brownian motion advection-diffusion local time
2010/12/14
Advective skew dispersion is a natural Markov process defined by a diffusion with drift across an interface of jump discontinuity in a piecewise constant diffusion coefficient.
