Data Processing Protocol for Regression of Geothermal Times Series with Uneven Intervals [PDF]
, 2019 Regression of data generated in simulations or experiments has important implications in sensitivity studies, uncertainty analysis, and prediction accuracy. Depending on the nature of the physical model, data points may not be evenly distributed.

A one-parameter family of interpolating kernels for Smoothed Particle Hydrodynamics studies [PDF]
, 2008 A set of interpolating functions of the type f(v)={(sin[v pi/2])/(v pi/2)}^n is analyzed in the context of the smoothed-particle hydrodynamics (SPH) technique.

Knot selection by boosting techniques [PDF]
, 2006 A novel concept for estimating smooth functions by selection techniques based on boosting is developed. It is suggested to put radial basis functions with different spreads at each knot and to do selection and estimation simultaneously by a componentwise

Implication of Omega_m through the Morphological Analysis of Weak Lensing Fields
, 2001 We apply the morphological descriptions of two-dimensional contour map, the so-called Minkowski functionals (the area fraction, circumference, and Euler characteristics), to the convergence field $\kappa(\bm{\theta})$ of the large-scale structure ...

Exploring the dynamics of monkeypox transmission with data-driven methods and a deterministic model
Frontiers in EpidemiologyIntroductionMpox (formerly monkeypox) is an infectious disease that spreads mostly through direct contact with infected animals or people's blood, bodily fluids, or cutaneous or mucosal lesions. In light of the global outbreak that occurred in 2022–2023,

Baseline correction for NMR spectroscopic metabolomics data analysis. [PDF]
, 2008 BackgroundWe propose a statistically principled baseline correction method, derived from a parametric smoothing model. It uses a score function to describe the key features of baseline distortion and constructs an optimal baseline curve to maximize it ...

Systematic Effects on the Genus Topology of Large Scale Structure of the Universe
, 2014 Large-scale structure of the universe is a useful cosmological probe of the primordial non-Gaussianity and the expansion history of the universe because its topology does not change with time in the linear regime in the standard paradigm of structure ...

Accuracy of Mesh Based Cosmological Hydrocodes: Tests and Corrections [PDF]
, 1998 We perform a variety of tests to determine the numerical resolution of the cosmological TVD eulerian code developed by Ryu et al (1993). Tests include 512^3 and 256^3 simulations of a Pk=k^{-1} spectrum to check for self-similarity and comparison of ...
