Object-based modelling and accuracy assessment of Gordion tumuli using very high-resolution stereo satellite images

, 2021
Very high-resolution (VHR) stereo satellite images provide detailed spatial and spectral information for detecting and monitoring artificial or natural objects. This information can also be used for object-based change detection.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.

Stereo Matching of High-Resolution Satellite Images via Hierarchical ViT and Self-Supervised DINO [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Dense matching plays an important role in 3D modeling from satellite images. Its purpose is to establish pixel-by-pixel correspondences between two stereo images. This study presents a learning-based dense matching approach that integrates selfsupervised

Mechanism of Isonitrilase, a Nonheme Iron Decarboxylase Involved in the Biosynthesis of the Isonitrile Group in Peptides: A Computational Study

Chemistry – A European Journal, EarlyView.
A combination of molecular dynamics and quantum mechanics calculations shows that substrate is tightly bound inside the enzyme structure that enables two successive catalytic cycles with dioxygen and α‐ketoglutarate with an initial desaturation followed by hydrogen abstraction and decarboxylation steps to form an isonitrile substituent.

Detecting complex building shapes in panchromatic satellite images for digital elevation model enhancement [PDF]

, 2010
In recent years Digital Elevation Models (DEM) gained much interest because of their high capability to give information about urban regions. DEM can be used or detailed urban monitoring, change and damage detection purposes.

Performance Evaluation of Semi-Global Approaches for the Dense Image Matching of Stereo Satellite Images

, 2021
In this study, the performance of semi-global methods for satellite stereo image matching was investigated. The performance of semi-global methods for the well-known Middlebury and KITTI sets has been the subject of many studies.

Taxon‐dependent multisite species turnover in fragmented habitats: comparing zeta diversity across birds, butterflies, and cursorial hunting spiders

Ecography, EarlyView.
Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

A GF-based multi-source multi-temporal satellite benchmark for binocular disparity estimation

Geo-spatial Information Science
As the cost of small satellites decreases annually and their performance improves, hundreds of high-resolution satellites are now in orbit. This has increased the demand for satellite stereo processing toward detailed observations of the Earth.

Epileptic arousals: A neglected clinical entity

Epilepsia, EarlyView.
Abstract Objective Epileptic arousals (EAs) are seizures characterized solely by arousal from sleep. EAs are unrecognized in current seizure classifications. Their subtle semiology and inconsistently detectable ictal activity in scalp electroencephalography (EEG) complicate differentiation from physiological arousals (PAs). This study characterizes EAs
