Higher Criticism for Detecting Sparse Heterogeneous Mixtures
Multiple Comparsions Combining Many p-values
2015/8/21
Higher Criticism, or second-level significance testing, is a multiple comparisons concept
mentioned in passing by Tukey (1976). It concerns a situation where there are many independent tests of...

massively parallel fast-multipole method heterogeneous architectures
2015/7/15
We present new scalable algorithms and an implementation of the kernel-independent fast multiple method (KIFMM), employing hybrid distributed memory message passing (via MPI) and shared memory/streami...

Helmholtz time-harmonic sweeping preconditioner parallel
2015/7/14
A parallelization of a sweeping preconditioner for 3D Helmholtz equations without internal resonance is introduced and benchmarked for several challenging velocity models. The setup and application co...
Traveling waves in a one-dimensional heterogeneous medium
Traveling waves one-dimensional heterogeneous medium
2015/7/14
We consider solutions of a scalar reaction-diffusion equation of the ignition type with a random, stationary and ergodic reaction rate. We show that solutions of the Cauchy problem spread with a deter...
EXPLORING THE EFFECTS OF SOCIAL PREFERENCE,ECONOMIC DISPARITY,AND HETEROGENEOUS ENVIRONMENTS ON SEGREGATION
subject classifications
2015/7/14
It is believed that social preference, economic disparity, and heterogeneous environments are mechanisms for segregation. However, it is difficult to unravel the exact role of each mechanism in such a...
