Efficient Generation of Model Bulk Heterojunction Morphologies for Organic Photovoltaic Device Modeling

open access: yes, 2014
Kinetic Monte Carlo (KMC) simulations have been previously used to model and understand a wide range of behaviors in bulk heterojunction (BHJ) organic photovoltaic devices, from fundamental mechanisms to full device performance.

Modeling the effect of soil meso- and macropores topology on the biodegradation of a soluble carbon substrate [PDF]

open access: yes, 2015
Soil structure and interactions between biotic and abiotic processes are increasingly recognized as important for explaining the large uncertainties in the outputs of macroscopic SOM decomposition models.

Analysis and multi-dimensional modeling of lithium-air batteries [PDF]

open access: yes, 2014
This study contributes to: 1) a multi-dimensional model framework of lithium-air (Li-air) battery, 2) incorporation of mechanisms of insoluble precipitates' impacts, and 3) analysis and discussion on oxygen supply channel for Li-air battery.

Globally and Locally Minimal Weight Spanning Tree Networks

open access: yes, 2001
The competition between local and global driving forces is significant in a wide variety of naturally occurring branched networks. We have investigated the impact of a global minimization criterion versus a local one on the structure of spanning trees ...

A Numerical Study on Chloride Diffusion in Cracked Concrete

open access: yesCrystals, 2021
The cracks in concrete are a fast transport path for chlorides and influence the service life of concrete structures in chloride environments. This study aimed to reveal the effect of crack geometry on chloride diffusion in cracked concrete. The chloride

Arterial Tortuosity Syndrome [PDF]

open access: yesCirculation, 2008
Arterial tortuosity syndrome is a recently defined rare genetic syndrome with autosomal recessive inheritance characterized by elongation, tortuosity, stenosis, and aneurysm formation of major arteries. These images are of a 1-year-old girl with arterial tortuosity syndrome.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Computational approaches for tortuosity determination in 3D structures [PDF]

open access: yes, 2013
Tortuosity is a parameter of key importance to study transport properties in either solid phase (thermal, electrical) and/or fluid phase (acoustics, mass/heat flow, etc). This structure-related parameter expresses mathematically the real pathway distance

Extracting 3D parametric curves from 2D images of Helical objects [PDF]

open access: yes, 2017
Helical objects occur in medicine, biology, cosmetics, nanotechnology, and engineering. Extracting a 3D parametric curve from a 2D image of a helical object has many practical applications, in particular being able to extract metrics such as tortuosity ...

An innovative agent-based technique for determination of tortuosity in porous materials – Case study: bread and bread dough

open access: yesCurrent Research in Food Science
Tortuosity is an important structural parameter of porous materials, and it is the ratio of the actual distance between two points to the shortest linear distance between them.
