Assessing soil surface roughness decay during simulated rainfall by multifractal analysis [PDF]

Nonlinear Processes in Geophysics, 2008
Understanding and describing the spatial characteristics of soil surface microrelief are required for modelling overland flow and erosion. We employed the multifractal approach to characterize topographical point elevation data sets acquired by high ...

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Next Generation Smart Implant Surfaces: Engineering Multifunctional Antimicrobial, Immunomodulatory and Regenerative Interfaces

Journal of Periodontal Research, EarlyView.
Natural‐inspired nano‐textured implant surfaces can be functionalised to modulate macrophage polarisation and local immune responses. This bioactive control promotes improved tissue integration and healing outcomes. ABSTRACT Dental implants rely on a stable and functional interface between the implant surface, surrounding tissues, and the oral ...

Divergent trajectories of genome architecture and chromosome evolution in ferns and angiosperms

New Phytologist, EarlyView.
Variation in key fern genomic traits across families, mapped onto a summary phylogenetic tree. Summary Ferns and angiosperms represent the two largest vascular plant lineages but exhibit striking genomic and ecological contrasts. We investigated whether differences in genome size, chromosome architecture, GC content, and stomatal traits reveal ...

Resistance of Overland Flow on Complex Microrelief [PDF]

AIP Conference Proceedings, 2011
Resistance problem of the overland flow on complex microrelief is intricated. The difficulty in evaluating the resistance mainly comes from the variety of flow status and the complex composition of the resistance. Finding out the correlation between resistance components and influence factors is believed valuable to this problem.
