Tourmaline 40Ar/39Ar chronology of tourmaline-rich rocks from Central Iberia dates the main Variscan deformation phases [PDF]

open access: yes, 2009
During crustal thickening, metapelites taken to depth release boron-bearing hydrothermal fluids because of progressive heating and dehydration. These fluids swiftly percolate upwards, especially if the crust is being actively deformed, to form tourmaline

Investigating a Domain Adaptation Approach for Integrating Different Measurement Instruments in a Longitudinal Clinical Registry

open access: yesBiometrical Journal, Volume 67, Issue 1, February 2025.
ABSTRACT In a longitudinal clinical registry, different measurement instruments might have been used for assessing individuals at different time points. To combine them, we investigate deep learning techniques for obtaining a joint latent representation, to which the items of different measurement instruments are mapped.

Enhanced Removal of Phenol from Aquatic Solution in a Schorl-catalyzed Fenton-like System by Acid-modified Schorl [PDF]

open access: yesBulletin of the Korean Chemical Society, 2010
). •OH is a very strong and non-specific oxidant which can oxidize almost all the organic compounds. However, the com-mon drawback of Fenton’s reaction is the generation of second-ary pollutants, the ferric ions. Another separation unit is required in the downstream of the process in order to recover the ferric ions from the treated wastewaters.

Frontoparietal network integrity supports cognitive function in pre‐symptomatic frontotemporal dementia: Multimodal analysis of brain function, structure, and perfusion

open access: yesAlzheimer's &Dementia, Volume 20, Issue 12, Page 8576-8594, December 2024.
Abstract INTRODUCTION Genetic mutation carriers of frontotemporal dementia can remain cognitively well despite neurodegeneration. A better understanding of brain structural, perfusion, and functional patterns in the pre‐symptomatic stage could inform accurate staging and potential mechanisms.
