Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Almost periodic function and rotation number of the Schrodinger operator
薛定谔算子 几乎周期函数 旋转数
2023/4/25
The concept of almost periodic functions is due to H. Bohr. The concept of rotation number is due to H. Poincaré. The Schr?dinger operator is named after E. Schr?dinger. I will present our work relate...

ROTATION-DEPENDENT CATASTROPHIC DISRUPTION OF GRAVITATIONAL AGGREGATES
minor planets asteroids:general planets and satellites:formation planets and satellites:physical evolution
2015/12/25
We carry out a systematic exploration of the effect of pre-impact rotation on the outcomes of low-speed collisions between planetesimals modeled as gravitational aggregates. We use pkdgrav, a cosmolog...
Asteroid rotation and shapes from numerical simulations of gravitational re-accumulation
Asteroids Asteroid formation Asteroid evolution Collisions
2015/12/25
We present simulations of the gravitational collapse of a mono-disperse set of spherical particles for studying shape and spin properties of re-accumulated members of asteroid families. Previous numer...
THE VISITS TO ZERO OF A RANDOM WALK DRIVEN BY AN IRRATIONAL ROTATION
RANDOM WALK DRIVEN IRRATIONAL ROTATION
2015/9/29
The method is to nd the asymptotic behavior of the ergodic sums of L1
functions for linear
ows on the in nite staircase surface.
Our methods also provide a new proof of J. Beck's central limit th...
Palaeomagnetic results from an archaeological site near Rome (Italy): new insights for tectonic rotation during the last 0.5 Myr
palaeomagnetism block rotation active tectonics Rome
2015/9/15
Approximately 20 km north-east of Rome, along the modern trace of the Tiburtina road, recent archaeological diggings have brought to light a system of aqueduct galleries constructed by Roman engineers...
3D dynamic simulations of spontaneous rupture propagation governed by different constitutive laws with rake rotation allowed
earthquake dynamics numerical modeling friction laws slip time history rake rotation
2015/9/10
In this work we present a 3D Finite Difference numerical method to model the dynamic spontaneous propagation
of an earthquake rupture on planar faults in an elastic half-space. We implement the Tract...
PARALLEL CHIP-FIRING ON THE COMPLETE GRAPH;DEVIL’S STAIRCASE AND POINCARE ROTATION NUMBER
PARALLEL CHIP-FIRING COMPLETE GRAPH DEVIL’S STAIRCASE POINCARE ROTATION NUMBER
2015/8/14
We study how parallel chip-firing on the complete graph Kn changes behavior as we vary the total number of chips. Surprisingly,the activity of the system, defined as the average number of firings per ...

2015/3/18
Researchers at the Universities of Strathclyde and Pittsburgh, and Princeton University, conducted a test in which they were able to arrange the particles into a ‘ring geometry’ form in a solid-state ...
Cenozoic tectonic rotation of the Mojave Desert, California as indicated by paleomagnetic studies
The mojave desert crustal movement paleomagnetism volcanoes the earth's crust
2014/10/22
Strain distribution across broad plate boundaries is inadequately understood. California's Mojave Desert has been adjacent to Tertiary convergent and transform plate margins and its general geology is...
Rake rotation introduces ambiguity in the formulation of slip-dependent constitutive models: slip modulus or slip path?
Constitutive laws Slip-weakening Rake rotation Dynamic models of faults
2015/8/18
The linear slip–weakening (SW) law, predicting that the traction decreases for increasing fault slip, is one of the most widely adopted governing models to describe the traction evolution and the stre...
A Fast Classification Method for Single-Particle Projections with a Translation and Rotation Invariant
Classification Fourier transform Translationand rotation invariant Secondary-class.
2012/8/7
The aim of the electron microscopy image classification is to categorize the projection
images into different classes according to their similarities. Distinguishing images
usually requires that the...
