Packing and Hausdorff measures of stable trees [PDF]

open access: yes, 2010
In this paper we discuss Hausdorff and packing measures of random continuous trees called stable trees. Stable trees form a specific class of L\'evy trees (introduced by Le Gall and Le Jan in 1998) that contains Aldous's continuum random tree (1991 ...

Packing dimension of mean porous measures [PDF]

open access: yesJournal of the London Mathematical Society, 2009
We prove that the packing dimension of any mean porous Radon measure on $\mathbb R^d$ may be estimated from above by a function which depends on mean porosity. The upper bound tends to $d-1$ as mean porosity tends to its maximum value.

Square packings and rectifiable doubling measures

open access: yesDiscrete Analysis, 2023
Square packings and rectifiable doubling measures, Discrete Analysis 2025:3, 40 pp. A measure $\mu$ on a metric space is $m$-rectifiable if it assigns full measure to a countable collection of Lipschitz images of bounded subsets of $\mathbb{R}^m ...

Are these crystals isostructural? Symmetry requirements, extent of difference, and likeness of supramolecular interactions [PDF]

open access: yesStructural Dynamics
The intentional design of crystalline materials, the fine-tuning of physical and chemical properties by slight chemical alterations - crystal engineering - requires understanding of solid-state assembly including supramolecular interactions and ...

On the Fractal Measures and Dimensions of Image Measures on a Class of Moran Sets

open access: yesMathematics, 2023
In this work, we focus on the centered Hausdorff measure, the packing measure, and the Hewitt–Stromberg measure that determines the modified lower box dimension Moran fractal sets. The equivalence of these measures for a class of Moran is shown by having

Packing dimensions of basins generated by distributions on a finite alphabet

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2021
We consider a space of infinite signals composed of letters from a finite alphabet. Each signal generates a sequence of empirical measures on the alphabet and the limit set corresponding to this sequence.

A study on calculation of friction coefficient and packing stress using static diagnosis test for a balanced globe valve in nuclear power plants

open access: yesNuclear Engineering and Technology, 2021
A valve assembly used in nuclear power plants must be qualified and supervised. New technical standards such as ASME QME-1 2007 particularly require detailed qualification using experiment and analysis.

Too packed to change: side-chain packing and site-specific substitution rates in protein evolution [PDF]

open access: yesPeerJ, 2015
In protein evolution, due to functional and biophysical constraints, the rates of amino acid substitution differ from site to site. Among the best predictors of site-specific rates are solvent accessibility and packing density.

On the general relationship between plant height and aboveground biomass of vegetation stands in contrasted ecosystems.

open access: yesPLoS ONE, 2021
Ecological communities are unique assemblages of species that coexist in consequence of multi-causal processes that have proven hard to generalize. One possible exception are processes that control the biomass packing of vegetation stands; the amount of ...

Comparison of side-chain dispersion in protein structures determined by cryo-EM and X-ray crystallography

open access: yesIUCrJ, 2022
An evaluation of systematic differences in local structure and conformation in the interior of protein tertiary structures determined by crystallography and by cryo-electron microscopy (cryo-EM) is reported.
