Introduction: Two main types of unmelted mi-crometeorite are recognised: (1) fine-grained micro-meteorites (fgMMs), dominated by phyllosilicates, and (2) coarse-grained micrometeorites (cgMMs), dominated by anhydrous silicates and glass with magmatic textures [1]. Fine-grained MMs have close affinities to the matrices of CI, CM2 and CR2 chondrites, however, the other major components of these m...

Several studies have shown that people's memory for location can be influenced by categorical information. According to a model proposed by Huttenlocher, Hedges, and Duncan (1991), people estimate location by combining fine-grained item-level information in memory with category-level information. When the fine-grained information is inexact, category-level information is given greater weight, w...

An integrated nomenclature scheme is proposed to capture the inherent heterogeneity of fine-grained sedimentary rocks at the 102 to 1023 mm scale and to assist the evaluation of these rocks as sinks of organic carbon, barriers to fluid flows, and reservoirs of oil and gas. This scheme incorporates previous knowledge and the latest field, petrographic, and laboratory observations. We propose to ...

Introduction: Recent work on Wild2 cometary samples shows evidence for sampling of high-T grains that have strong similarities to components in carbonaceous chondrites. Such grains in cometary samples have been used as evidence for large-scale radial mixing in the early Solar System [1,2]. However, Wild2 samples are biased towards relatively coarse-grained material, with finer-grained component...

In this paper we present a novel technique for unsupervised texture segmentation of wireless capsule endoscopic images of the human gastrointestinal tract. Our approach integrates local polynomial approximation algorithm with the well-founded methods of color texture analysis and clustering (k-means) leading to a robust segmentation procedure which produces fine-grained segments well matched to...

Ultrafine-grained (UFG) Ti for improved mechanical performance as well as its surface modification enhancing biofunctions has attracted much attention in medical industries. Most of the studies on the surface etching of metallic biomaterials have focused on surface topography and wettability but not crystallographic orientation, i.e., texture, which influences the chemical as well as the physic...

The island of Syros consists largely of possibly-repeated sequences of glaucophane-bearing calcareous schists, mafic schists, dolomite marbles, and calcite marbles containing abundant aragonite pseudomorphs (Dixon, 1969; Hecht, 1984). Several discrete, fault-bounded packages of blueschist/eclogite-facies mafic rocks with minor serpentinite are also found on the island. Although the mafic rocks ...
