Palaeoproteomic Deconvolution of Physical and Genetic Collagen Mixtures

Advanced Science, EarlyView.
ClassiCOL_v2 uses a novel “peptide patching” framework that treats any collagen sample as a patchwork of peptide sequences derived from phylogenetically related species. This allows the algorithm to simultaneously resolve two previously intractable problems: multi‐species samples and/or database deficiencies.

The narrative process and the geological process: the narrative of the geological history of a natural site

, 2022
Nous nous intéressons à la reconstitution de l’histoire géologique d’un géo-site par un médiateur scientifique qui intervient « sur le terrain ». Une telle médiation suppose d’articuler la topographie de l’excursion avec le parcours narratif mis en place par le médiateur.Nous montrons que la mise en récit pré-figure les événements géologiques en ...

In Situ CO2‐Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers

Advanced Science, EarlyView.
A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...

Attention and Geological Knowledge Guided Spectral‐Spatial Networks for Geochemical Anomalies Recognition

Journal of Geophysical Research: Machine Learning and Computation
Achieving both accuracy and interpretability in deep learning models for geochemical anomaly recognition constitutes a significant challenge. To overcome this challenge, this study developed a novel interpretable dual‐branch network combining a spectral ...

Submarine fresh groundwater discharge estimation in the intertidal zone based on dynamic salinity simulation

Shuiwen dizhi gongcheng dizhi
Currently, limited studies focused on the variations in submarine fresh groundwater discharge rates, seawater recirculation rates, and their respective proportions with tidal level change in sandy intertidal zones.

Groundwater in Geologic Processes

Eos, Transactions American Geophysical Union, 2000
Any student of geology who inspects a sample of galena or fluorite from one of the lead‐zinc mines of the Mississippi Valley Ore district will be immediately struck by the hydrologic processes that were required to concentrate the requisite far‐flung chemical components into a relatively thin layer of limestone.

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

Advanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Development of perennial thaw zones in boreal hillslopes enhances potential mobilization of permafrost carbon

Environmental Research Letters, 2019
Permafrost thaw alters subsurface flow in boreal regions that in turn influences the magnitude, seasonality, and chemical composition of streamflow. Prediction of these changes is challenged by incomplete knowledge of timing, flowpath depth, and amount ...
