The packing measure of the support of super-Brownian motion

open access: yes, 1995
Our object is to obtain more information about the fractal properties of super-Brownian motion. For d ⩾ 2 the closed support S(Yt) of super-Brownian motion has zero Lebesgue measure and fractal dimension 2. The exact Hausdorff measure properties of S(Yt)

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.

Computability of the packing measure of totally disconnected self-similar sets [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2014
We present an algorithm to compute the exact value of the packing measure of self-similar sets satisfying the so called Strong Separation Condition (SSC) and prove its convergence to the value of the packing measure.

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 ...

On the packing measure of slices of self-similar sets [PDF]

open access: yes, 2013
Let $K \subset \mathbb{R}^{2}$ be a rotation and reflection free self-similar set satisfying the strong separation condition, with dimension $\dim K = s > 1$.

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.

Automated packing systems - a systems engineering approach [PDF]

open access: yes, 1996
The ability to manipulate previously unseen objects under visual control is one of the key tasks in the successful implementation of robotic, automated assembly and adaptive material handling systems.
