Greenland Ice Sheet Surface Topography and Drainage Structure Controlled by the Transfer of Basal Variability

open access: yesFrontiers in Earth Science, 2018
Ice flow can transfer variations in basal topography and basal slipperiness to the ice surface. Recent developments in this theory have made it possible to conduct numerical experiments to predict mesoscale surface topographical undulations and surface ...

Hierarchical Micro-Nano Topography Promotes Cell Adhesion and Osteogenic Differentiation via Integrin α2-PI3K-AKT Signaling Axis

open access: yesFrontiers in Bioengineering and Biotechnology, 2020
Surface topography dictates important aspects of cell biological behaviors. In our study, hierarchical micro-nano topography (SLM-AHT) with micro-scale grooves and nano-scale pores was fabricated and compared with smooth topography (S) and irregular ...

Nail Surface Topography and Onychochronobiology [PDF]

open access: yes, 2013
Nail surface changes are observed during aging and in some chronic inflammatory dermatoses. Descriptive terms are commonly used, but quantitative analytic measurements are welcome to increase sensitivity, precision, and reproducibility of observations. Bioinstrumentation, particularly optical profilometry, allows both static and repetitive assessments ...

On the limit to resolution and information on basal properties obtainable from surface data on ice streams [PDF]

open access: yesThe Cryosphere, 2008
An optimal estimation method for simultaneously determining both basal slipperiness and basal topography from variations in surface flow velocity and topography along a flow line on ice streams and ice sheets is presented.

Accelerated bone formation by biphasic calcium phosphate with a novel sub-micron surface topography [PDF]

open access: yesEuropean Cells & Materials, 2019
Osteoinductive calcium phosphate (CaP) bone grafts have equivalent performance to autografts in repairing critical-size bone defects. The osteoinductive potential of CaP is linked to the size of the surface topographical features.
