On the Ambartzumian-Pleijel identity in hyperbolic geometry [PDF]

open access: yes, 2014
We describe a hyperbolic version of the Ambartzumian-Pleijel identity. We use this identity to prove the hyperbolic Crofton formula and the hyperbolic isoperimetric inequality.

Experiment K-6-12. Morphometric studies of atrial or granules and hepatocytes. Part 1: Morphometric study of the liver; Part 2: The atrial granular accumulations [PDF]

open access: yes
The livers of flight, F, rats from the Cosmos 1887 mission were markedly paler and heavier than those of the synchronous, S, and vivarium, V, controls. In the F group, microscopic study revealed extensive hepatocytic intracytoplasmic vacuolization which ...

STEREOLOGICAL ESTIMATION OF SURFACE AREA FROM DIGITAL IMAGES

open access: yesImage Analysis and Stereology, 2011
A sampling design of local stereology is combined with a method from digital stereology to yield a novel estimator of surface area based on counts of configurations observed in a digitization of an isotropic 2- dimensional slice with thickness s.

Using curcumin to prevent structural impairments of testicles in rats induced by sodium metabisulfite [PDF]

open access: yes, 2017
Sodium metabisulfite (Na-MBS) is a disinfectant and preservative agent. Some organ including testicle would be in danger in the case of Na-MBS consumption. Curcumin (CUR) is the constituent of turmeric with protective properties.

Classification of lung disease in HRCT scans using integral geometry measures and functional data analysis [PDF]

open access: yes, 2010
A framework for classification of chronic lung disease from high-resolution CT scans is presented. We use a set of features which measure the local morphology and topology of the 3D voxels within the lung parenchyma and apply functional data classification

Systematic sampling with errors in sample locations [PDF]

open access: yes, 2017
Systematic sampling of points in continuous space is widely used in microscopy and spatial surveys. Classical theory provides asymptotic expressions for the variance of estimators based on systematic sampling as the grid spacing decreases.

Characterizing the dual mixed volume via additive functionals [PDF]

open access: yes, 2013
Integral representations are obtained of positive additive functionals on finite products of the space of continuous functions (or of bounded Borel functions) on a compact Hausdorff space.

On the domain of attraction for the lower tail in Wicksell's corpuscle problem

open access: yes, 2006
We consider the classical Wicksell corpuscle problem with spherical particles in R^n and investigate the shapes of lower tails of distributions of `sphere radii' in R^n and `sphere radii' in a k-dimensional section plane. We show in which way the domains
