Symmetrized importance samplers for stochastic differential equations [PDF]

, 2018
We study a class of importance sampling methods for stochastic differential equations (SDEs). A small-noise analysis is performed, and the results suggest that a simple symmetrization procedure can significantly improve the performance of our importance ...

Efficient Computation of Collatz Sequence Stopping Times: A Novel Algorithmic Approach

IEEE Access
The Collatz conjecture, which posits that any positive integer will eventually reach 1 through a specific iterative process, is a classic unsolved problem in mathematics.

Study on MOOC scoring algorithm based on Chinese University MOOC learning behavior data

Heliyon, 2018
Existing online learning evaluation methods do not accurately reflect learning effects, which only considers test and assignment scores. A comprehensive evaluation algorithm is proposed in this paper based on the big data of learning behavior.

Computational reverse mathematics and foundational analysis [PDF]

, 2018
Reverse mathematics studies which subsystems of second order arithmetic are equivalent to key theorems of ordinary, non-set-theoretic mathematics. The main philosophical application of reverse mathematics proposed thus far is foundational analysis, which

The Expected Norm of a Sum of Independent Random Matrices: An Elementary Approach [PDF]

, 2015
In contemporary applied and computational mathematics, a frequent challenge is to bound the expectation of the spectral norm of a sum of independent random matrices.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

Molecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Heat transfer enhancement in the boundary layer flow of hybrid nanofluids due to variable viscosity and natural convection

Heliyon, 2019
The aim of the current work is to explore how heat transfer can be enhanced by variations in the basic properties of fluids in the presence of free convection with the aid of suspended hybrid nanofluids.

Long time dynamics and coherent states in nonlinear wave equations

, 2016
We discuss recent progress in finding all coherent states supported by nonlinear wave equations, their stability and the long time behavior of nearby solutions.Comment: bases on the authors presentation at 2015 AMMCS-CAIMS Congress, to appear in Fields
