Improved allometric models to estimate the aboveground biomass of younger secondary tropical forests

open access: yesGlobal Ecology and Conservation, 2023
Frequent human activities have resulted in a large number of tropical old-growth forests being replaced by secondary forests at different succession stages.

Simultaneous fitting of neutron star structure and cooling data

open access: yesPhysical Review C, 2019
Using a model for the equation of state and composition of dense matter and the magnitude of singlet proton superconductivity and triplet neutron superfluidity, we perform the first simultaneous fit of neutron star masses and radii determined from observations of quiescent low-mass x-ray binaries and luminosities and ages determined from observations ...

Simultaneous probability statements for Bayesian P-splines [PDF]

open access: yes, 2005
P-splines are a popular approach for fitting nonlinear effects of continuous covariates in semiparametric regression models. Recently, a Bayesian version for P-splines has been developed on the basis of Markov chain Monte Carlo simulation techniques for

Optimizing acquisition and fitting conditions for 1 H MR spectroscopy investigations in global brain pathology. [PDF]

open access: yes, 2019
PURPOSE To optimize acquisition and fitting conditions for nonfocal disease in terms of voxel size and use of individual coil element data. Increasing the voxel size yields a higher signal-to-noise ratio, but leads to larger linewidths and more ...

Partial least square regression applied to the QTLMAS 2010 dataset

open access: yes, 2010
Detection of genomic regions affecting traits is a goal in many genetic studies. Studies applying distinct methods for detection of these regions, called quantitative trait loci (QTL), have been described, ranging from single marker regression [1] to ...

Studies on the differential equations of enzyme kinetics. II. bimolecular reaction: the fitting of experimental data to the simplified model

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
Efficient and unbiased estimates of the parameters of the differential system, as well as simultaneous fiducial limits, are obtained through an (eventually weighted) least-squares fitting to a Taylor expansion of the concentration of the products of the ...

Bioassay Analysis Using R

open access: yesJournal of Statistical Software, 2005
We describe an add-on package for the language and environment R which allows simultaneous fitting of several non-linear regression models. The focus is on analysis of dose response curves, but the functionality is applicable to arbitrary non-linear ...

Methods to derive the magnetopause from soft X-ray images by the SMILE mission

open access: yesGeoscience Letters, 2022
Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a novel self-standing mission dedicated to observing the solar wind–magnetosphere coupling via simultaneous in situ solar wind/magnetosheath plasma and magnetic field measurements, soft X-ray ...
