THICKNESS OF THE SURFACE LAYER OF ATOMIC-SMOOTH CRYSTALS

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2019
A brief review of the physics of the surface layer of atomically smooth crystals is given. It already contains a fairly large number of practical applications in various fields of interdisciplinary areas.

The effect of neighborhood size on effective population size in theory and in practice [PDF]

open access: yesHeredity, 2016
The distinction between the effective size of a population (Ne) and the effective size of its neighborhoods (Nn) has sometimes become blurred. Ne reflects the effect of random sampling on the genetic composition of a population of size N, whereas Nn is a measure of within-population spatial genetic structure and depends strongly on the dispersal ...

Markowitz efficiency and size effect: evidence from the UK stock market

open access: yes, 2014
Academics and practitioners have frequently debated the relationship between market capitalization and expected return. We apply the Markowitz efficient frontier approach to develop a portfolio performance measure that compares the return of a portfolio ...

Prediction of forming limits for porous materials using void-size dependent model and bifurcation approach [PDF]

open access: yes, 2020
The scientific literature has shown the strong effect of void size on material response. Several yield functions have been developed to incorporate the void size effects in ductile porous materials.

Size-Tunable Natural Mineral-Molybdenite for Lithium-Ion Batteries Toward: Enhanced Storage Capacity and Quicken Ions Transferring

open access: yesFrontiers in Chemistry, 2018
Restricted by the dissatisfied capacity of traditional materials, lithium-ion batteries (LIBs) still suffer from the low energy-density. The pursuing of natural electrode resources with high lithium-storage capability has triggered a plenty of activities.

Standardized or simple effect size: what should be reported?

open access: yes, 2009
It is regarded as best practice for psychologists to report effect size when disseminating quantitative research findings. Reporting of effect size in the psychological literature is patchy – though this may be changing – and when reported it is far from

A Size Effect Model Combining Both Surface Effects and the Fracture Process Zone (FPZ) for Rocks under Uniaxial Compression

open access: yesApplied Sciences
Developing a size effect model that can encompass the surface effect and the fracture process zone (FPZ) is still challenging. Here, a combined size effect model (CSE model) is formulated by integrating the surface effect size model and the size effect ...
