Nonlinear elastic polymers in random flow
, 2005 Polymer stretching in random smooth flows is investigated within the framework of the FENE dumbbell model. The advecting flow is Gaussian and short-correlated in time.

On asymptotically optimal wavelet estimation of trend functions under long-range dependence
, 2012 We consider data-adaptive wavelet estimation of a trend function in a time series model with strongly dependent Gaussian residuals. Asymptotic expressions for the optimal mean integrated squared error and corresponding optimal smoothing and resolution ...

Multiscale adaptive smoothing models for the hemodynamic response function in fMRI
The Annals of Applied Statistics, 2013 In the event-related functional magnetic resonance imaging (fMRI) data analysis, there is an extensive interest in accurately and robustly estimating the hemodynamic response function (HRF) and its associated statistics (e.g., the magnitude and duration of the activation).

Multivariate Contemporaneous-Threshold Autoregressive Models [PDF]
This paper proposes a contemporaneous-threshold multivariate smooth transition autoregressive (C-MSTAR) model in which the regime weights depend on the ex ante probabilities that latent regime-specific variables exceed certain threshold values.

Smooth Sigmoid Surrogate (SSS): An Alternative to Greedy Search in Decision Trees
MathematicsGreedy search (GS) or exhaustive search plays a crucial role in decision trees and their various extensions. We introduce an alternative splitting method called smooth sigmoid surrogate (SSS) in which the indicator threshold function used in GS is ...

, 2017 We introduce a generalization of the linearized Alternating Direction Method of Multipliers to optimize a real-valued function $f$ of multiple arguments with potentially multiple constraints $g_\circ$ on each of them. The function $f$ may be nonconvex as

Airway smooth muscle cells respond directly to inhaled environmental factors
Swiss Medical Weekly, 2010 A misled or overreacting immune response is assumed to be the major cause of the most prevalent chronic inflammatory lung diseases, asthma and chronic obstructive pulmonary disease (COPD).

When topology triggers a phase transition
, 2005 Two mathematical mechanisms, responsible for the generation of a thermodynamic singularity, are individuated. For a class of short-range, confining potentials, a topology change in some family of configuration space submanifolds is the only possible such
