New Insights Into the Paleoseismic History of the Mae Hong Son Fault, Northern Thailand
Frontiers in Earth Science, 2022 The Mae Hong Son Fault (MHSF) is a north-trending active fault in northern Thailand. The largest earthquake ever recorded in Thailand occurred in February 1975 with a magnitude of 5.6 and was associated with the southern end of the MHSF.

Morphology of ion-sputtered surfaces [PDF]
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002 We derive a stochastic nonlinear continuum theory to describe the morphological evolution of amorphous surfaces eroded by ion bombardment. Starting from Sigmund's theory of sputter erosion, we calculate the coefficients appearing in the continuum equation in terms of the physical parameters characterizing the sputtering process.

Surface Morphology of Human Leukocytes [PDF]
Blood, 1971 Abstract Surface morphology of individual leukocytes was correlated with their light microscopic appearance by a simple, direct technique. Circulating leukocytes of all types were roughened spheres with diameters similar to red cells, and leukocyte types could not be distinguished consistently by surface morphology. After surface contact,

Surface-chemical and -morphological gradients [PDF]
Soft Matter, 2008 Surface gradients of chemistry or morphology represent powerful tools for the high-throughput investigation of interfacial phenomena in the areas of physics, chemistry, materials science and biology. A wide variety of methods for the fabrication of such gradients has been developed in recent years, relying on principles ranging from diffusion to time ...

Evidence of coastal landforms and age determination related to the sealevel change at Nakhon Si Thammarat province in southern Thailand [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2023 We present evidence of sea-level changes over the past 15,000 years from dating sandy beach sediments in Nakhon Si Thammarat province. First, we classified various types of coastal landforms from satellite images.

Evidence for intermolecular forces involved in ladybird beetle tarsal setae adhesion
Scientific Reports, 2021 Why can beetles such as the ladybird beetle Coccinella septempunctata walk vertically or upside-down on a smooth glass plane? Intermolecular and/or capillary forces mediated by a secretion fluid on the hairy footpads have commonly been considered the ...

Mini Review: Comparison of Bio-Inspired Adhesive Feet of Climbing Robots on Smooth Vertical Surfaces
Frontiers in Bioengineering and Biotechnology, 2021 Developing climbing robots for smooth vertical surfaces (e.g., glass) is one of the most challenging problems in robotics. Here, the adequate functioning of an adhesive foot is an essential factor for successful locomotion performance.

Morphology and surface reconstructions of GaN(11̄00) surfaces [PDF]
Applied Physics Letters, 2003 GaN is grown by plasma-assisted molecular-beam epitaxy on ZnO(11̄00) substrates. Well-oriented (11̄00) GaN surfaces are obtained, and (11̄01) oriented facets are also observed. On the GaN(11̄00) surfaces under Ga-rich conditions, a surface reconstruction with approximate symmetry of “4×5” is found.
