Hyperspectral remote sensing in lithological mapping, mineral exploration, and environmental geology: an updated review

open access: yesJournal of Applied Remote Sensing, 2021
. Hyperspectral imaging has been used in a variety of geological applications since its advent in the 1970s. In the last few decades, different techniques have been developed by geologists to analyze hyperspectral data in order to quantitatively extract ...

Subglacial roughness of the Greenland Ice Sheet: relationship with contemporary ice velocity and geology

open access: yesThe Cryosphere, 2019
. The subglacial environment of the Greenland Ice Sheet (GrIS) is poorly constrained both in its bulk properties, for example geology, the presence of sediment, and the presence of water, and interfacial conditions, such as roughness and bed rheology ...

Snowball Earth climate dynamics and Cryogenian geology-geobiology

open access: yesScience Advances, 2017
We review recent observations and models concerning the dynamics of Cryogenian global glaciation and their biological consequences. Geological evidence indicates that grounded ice sheets reached sea level at all latitudes during two long-lived Cryogenian

Is Geology Scaling? [PDF]

open access: yesEarth and Space Science, 2019
AbstractConcept of fractals and power law in statistical and geometrical data sets is rather matured. However, the application part of the fractal theory is not yet commensurate with the theoretical literature available. In this invited review, we take a dig at the range of data sets to demonstrate their fractal/scaling behavior for instance well logs ...

Exam‐level analysis of lecture capture viewing and student exam performance

open access: yesFEBS Open Bio, EarlyView.
This study asks how lecture capture relates to exam performance in biology courses with three noncumulative exams. Mixed‐effects modeling separated between‐students from within‐student effects on exam %. Students who watched more recordings earned higher grades, but viewing spikes above a student's own mean, consistent with cramming, predicted small ...

Stable and Dendrite‐Free Zinc Metal Anodes Via Interface Nanoarchitectonics for Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This review explores Zn anode challenges in aqueous ZIBs, including dendrites, corrosion, and side reactions, and discusses strategies for improvement through Zn anode, electrolyte, and separator modifications to enhance stability and efficiency. Abstract Aqueous rechargeable zinc‐ion batteries (ZIBs) are emerging as promising candidates for next ...
