Geochemistry of trace and rare earth elements of the productive intrusions in the Kuh-Kapout porphyry copper deposit, Urumieh–Dokhtar magmatic arc [PDF]

open access: yesپترولوژی
IntroductionThe Cenozoic Urumieh-Dokhtar magmatic arc has characteristics similar to those of Andean-type magmatic arcs. Various types of magmatism occurred in this arc including calc-alkaline and K-rich calc-alkaline magmatism and less of them alkaline ...

Novae on Venus: Geology, classification, and evolution

open access: yes, 2003
[1] Novae are “radially fractured centers” 100–300 km in diameter, and 64 have been identified on Venus. Dense radial fracturing and upraised topography are common, and massive amounts of volcanism are seen in some. Novae are interpreted to be the result

Post‐disturbance evolution of a prograded foredune barrier during a sustained dynamic restoration project—the role of wind speed, wind direction and vegetation

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3435-3452, December 2022., 2022
Comparative photographs showing the change in dune morphology and vegetation cover at Doughboy Bay following a 12–15‐year period of sustained Ammophila arenaria control; from (a) densely vegetated shore‐aligned A. arenaria foredunes, to (b) sparsely vegetated wind‐aligned Ficinia spiralis nebkha.

Biogeomorphic recovery of a river reach affected by mining

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3497-3514, December 2022., 2022
The Grogwynion reach of the River Ystwyth,Wales, affected by mining in the 19th and 20th centuries, has shown a progressive reversion to a sinuous single‐channel planform since 2001 from an active braided pattern. A critical factor has been a change in the extent and type of riparian vegetation occurring within the active zone of the river due to the ...

Real-Time Head Gesture Recognition on Head-Mounted Displays using Cascaded Hidden Markov Models [PDF]

open access: yesJ. Zhao and R. S. Allison, "Real-time head gesture recognition on head-mounted displays using cascaded hidden Markov models," 2017 IEEE International Conference on Systems, Man, and Cybernetics (SMC), Banff, AB, 2017, pp. 2361-2366, 2017
Head gesture is a natural means of face-to-face communication between people but the recognition of head gestures in the context of virtual reality and use of head gesture as an interface for interacting with virtual avatars and virtual environments have been rarely investigated.
