Numerical Modeling of the Recession and Closure of Planar Hydraulic Fractures: Contact‐Based Versus Asymptotic‐Informed Schemes

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT We compare two algorithms to simulate the propagation, arrest, recession, and closure of a planar hydraulic fracture, focusing on their ability to capture the physical processes governing fracture recession and closure. The first algorithm is based on a fixed grid with contact detection during recession, while the second is based on a moving ...

Magma transfer at Campi Flegrei caldera (Italy) before the 1538 AD eruption

open access: yesScientific Reports, 2016
Calderas are collapse structures related to the emptying of magmatic reservoirs, often associated with large eruptions from long-lived magmatic systems.

Genetic Determinants of Fatty Acid Composition in Subcutaneous and Visceral Adipose Tissue

open access: yesObesity, EarlyView.
ABSTRACT Objective Fatty acids in adipose tissue are key structural and metabolic regulators of cardiometabolic health, but the genetic architecture governing depot‐specific composition in subcutaneous (SAT) and visceral adipose tissue (VAT) is not well defined.

MAGMA: Multi-level accelerated gradient mirror descent algorithm for large-scale convex composite minimization

open access: yes, 2016
Composite convex optimization models arise in several applications, and are especially prevalent in inverse problems with a sparsity inducing norm and in general convex optimization with simple constraints.

The magma thermal field and the shallow-level gas accumulation of tight gas reservoirs in the middle-eastern parts of the Qinshui Basin

open access: yesEarth Sciences Research Journal, 2019
In this study, the metal-non-metal mineral gas-water hydrothermal concept is used to analyze the movement channels of magmatic heating water. Further, the concept of fractures-faults-cracks microfissures hierarchical configuration of the movement ...

Ductility and Compressibility Accommodate High Magma Flux Beneath a Silicic Continental Rift Caldera: Insights From Corbetti Caldera (Ethiopia)

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Large silicic magma reservoirs preferentially form in the upper crust of extensional continental environments. However, our quantitative understanding of the link between mantle magmatism, silicic reservoirs, and surface deformation during rifting is ...

Mapping British Latinx Writing

open access: yesBulletin of Latin American Research, EarlyView.
There are an estimated quarter of a million Latin Americans living in the UK, yet they remain outside the British national imaginary. This invisibility has historically extended to the literary scene and publishing industry, with only very few British‐based Latin American and Latinx writers gaining any exposure.

Computadores aplicados a la clasificación química de las rocas ígneas. Métodos C.l.P.W. y NIGGLI

open access: yesBoletín Geológico, 1972
Existen diversos métodos para clasificar las rocas de acuerdo a su análisis químico. Uno de los más empleados ha sido el de C.I.P. W. que da una composición teórica calculada o normativa. Al contrario de la composición actual o modal de la misma. Esta

US graphite sourcing for electric vehicle battery applications

open access: yesJournal of Industrial Ecology, EarlyView.
Abstract Graphite is a key material in electric vehicle batteries. Currently, China dominates global graphite production, and US sourcing of graphite could mitigate geopolitical supply‐chain risk. We explore the feasibility of domestic natural graphite sourcing in North America by characterizing current deposits and modeling the expected demand from ...

Copper Isotope Studies of a Deep Ore Body in the Xinliaodong Copper-Polymetallic Deposit, Eastern Guangdong Province

open access: yesYankuang ceshi, 2017
The Xinliaodong copper-polymetallic deposit of Eastern Guangdong Province is one of newly discovered deposits. The ore district belongs to tin, tungsten, and copper ore cluster in the southeast coast, which have a very good ore-forming geological ...
