Large Deviations for Stochastic Evolution Equations with Small Multiplicative Noise [PDF]

, 2009
The Freidlin-Wentzell large deviation principle is established for the distributions of stochastic evolution equations with general monotone drift and small multiplicative noise.

Small Deviations from Gaussianity and The Galaxy Cluster Abundance Evolution [PDF]

, 2000
We raise the hypothesis that the density fluctuations field which originates the growth of large scale structures is a combination of two or more distributions.

Whole-brain opto-fMRI map of mouse VTA dopaminergic activation reflects structural projections with small but significant deviations

Translational Psychiatry, 2022
Ascending dopaminergic projections from neurons located in the Ventral Tegmental Area (VTA) are key to the etiology, dysfunction, and control of motivation, learning, and addiction.

Hypoelliptic multiscale Langevin diffusions: Large deviations, invariant measures and small mass asymptotics [PDF]

, 2017
We consider a general class of non-gradient hypoelliptic Langevin diffusions and study two related questions. The first one is large deviations for hypoelliptic multiscale diffusions.

Helioseismology can test the Maxwell-Boltzmann distribution [PDF]

, 1998
Nuclear reactions in stars occur between nuclei in the high-energy tail of the energy distribution and are sensitive to possible deviations from the standard equilibrium thermal-energy distribution.

Cancer patient survival can be parametrized to improve trial precision and reveal time-dependent therapeutic effects

Nature Communications, 2022
Analysis of more than 150 Phase 3 oncology clinical trials supports parametric statistical analysis, significantly increasing the precision of small early-phase trials and relating deviations from the Cox proportional hazards model to trial duration.

Study on the skiving process of an internal gear (Effects of axial feed rate on gear accuracy)

Nihon Kikai Gakkai ronbunshu, 2015
In this paper, study on the effects of axial feed rate on the gear accuracy is discussed. First, geometrical model of a skiving process was introduced. The model was assumed that the cutter was perfectly made and perfectly assembled to the skiving rig (i.

Alkaline Phosphatase and Disaccharide Activity in Barrett's Columnar Lined Esophagus

Canadian Journal of Gastroenterology, 1988
Esophageal mucosal biopsies of 15 patients with normal squamous epithelium, 11 with inflamed squamous epithelium and 23 with Barrete's columnar lined esophagus were assayed for alkaline phosphatase and disaccharidase activity.
