Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Application of trajectory optimization techniques to upper atmosphere sampling flights using the F-15 Eagle aircraft [PDF]
Atmospheric sampling has been carried out by flights using an available high-performance supersonic aircraft. Altitude potential of an off-the-shelf F-15 aircraft is examined. It is shown that the standard F-15 has a maximum altitude capability in excess

Deep Underground Science and Engineering, EarlyView.This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Ecography, EarlyView.Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

High altitude reconnaissance aircraft [PDF]
At the equator the ozone layer ranges from 65,000 to 130,000 plus feet, which is beyond the capabilities of the ER-2, NASA's current high altitude reconnaissance aircraft.

Ecography, EarlyView.Simulation outputs from forest landscape models are complex, and tools for their visual analysis and effective communication are often limited. In this paper, we present EcoViz, a novel, open‐source visualisation platform designed to complement existing forest models by providing advanced 3D visualisation capabilities.

Long and short arc altitude determination for GEOS-C [PDF]
The accuracy with which the GEOS-C altitude may be estimated over long (7 day) and short (40 minute) orbital arcs is investigated. Over the long are excellent agreement was attained between a simulation of the orbit determination process and a covariance

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra
Ecography, EarlyView.Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

Ecography, EarlyView.Globally, mountains are highly diverse ecosystems that serve as natural laboratories for testing ecological theories, while providing vital ecosystem services. Their biodiversity arises from the interaction between elevational gradients and topographic complexity, which generate strong variation in environmental conditions across short spatial scales ...
