Generalization of Barenblatt's cohesive fracture theory for fractal cracks
, 2002 In this paper, we generalize Barenblatt's cohesive fracture theory for fractal cracks. We discuss the difficulties of generalizing the concept of traction on a fractal surface.

A Coarse Geometric Approach to Graph Layout Problems
Journal of Graph Theory, EarlyView.ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...

Journal of Periodontology, EarlyView.Abstract Background This study investigates the impact of disruptions in testosterone levels on bone remodeling, root resorption, and periodontal ligament (PDL) during orthodontic tooth movement (OTM) in a pubertal male rat model. Methods Testosterone deficiency was induced through orchiectomy, and the anabolic‐androgenic steroid (AAS, testosterone ...

Land Degradation &Development, EarlyView.ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Fractal dimensions for unsaturated porous media
, 2004 The analytical expressions of the fractal dimensions for wetting and non-wetting phases for unsaturated porous media are derived and are found to be a function of porosity, maximum and minimum pore sizes as well as saturation.

On the Assembly of Actin Polymerization‐Powered Motors
Macromolecular Rapid Communications, EarlyView.Actin polymerization‐powered motors have the highest speed when the actin recruiting‐polymerizing proteins are immobilized in polymer brushes on their surface. These motors orbit around larger tracer particles at pH above the isoelectric point of ActA but dock onto the tracer particles’ surface at lower pH. ABSTRACT Nano‐ and micromotors are a class of
