Hydromechanical Modeling of Fault Rupture in Geologic CO2 Sequestration: A Comparison of Two Failure Criteria

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract The large‐scale implementation of geological carbon sequestration has raised concerns about potential fault activation and induced seismicity, which could compromise storage integrity and pose seismic risks. We theoretically compared two failure criteria, Mohr‐Coulomb (MC) and Modified Cam‐Clay criteria (MCC), to assess fault rupture during ...

Análise Em Regime Permanente Do Filtro Ativo Universal

Eletrônica de Potência, 2013
Este trabalho trata da análise do filtro ativo universal trifásico operando em regime permanente. Este tipo de topologia é capaz de compensar componentes harmônicas na corrente e na tensão, bem como minimizar a circulação energia reativa.

Towards zero variance estimators for rare event probabilities [PDF]

, 2012
Improving Importance Sampling estimators for rare event probabilities requires sharp approximations of conditional densities. This is achieved for events E_{n}:=(f(X_{1})+...+f(X_{n}))\inA_{n} where the summands are i.i.d.

Majority-vote on directed Small-World networks

, 2007
On directed Small-World networks the Majority-vote model with noise is now studied through Monte Carlo simulations. In this model, the order-disorder phase transition of the order parameter is well defined in this system.

Li isotopes in metal-poor halo dwarfs, a more and more complicated story [PDF]

, 2009
The nuclei of the lithium isotopes are fragile, easily destroyed, so that, at variance with most of the other elements, they cannot be formed in stars through steady hydrostatic nucleosynthesis.

Alimentação e distribuição de piaus (Pisces, Anostomidae) na Planície do Bananal, Mato Grosso, Brasil [PDF]

Revista Brasileira de Zoologia, 2004
Os peixes da família Anostomidae, conhecidos popularmente como piaus, são restritos à América do Sul e representam importante fonte de renda para pescadores de muitas regiões. Estudos na Amazônia Central demonstram que estes peixes apresentam alta plasticidade alimentar e estão amplamente distribuídos pela região.

Ontogeny of the Skeleton of Leporinus oliveirai (Characiformes, Anotomidae)

Journal of Morphology, Volume 286, Issue 5, May 2025.
In this study, we provide the first complete description of the skeleton ontogeny of an anostomid. The developmental sequence of 141 bony elements is described and illustrated. The main discoveries are numerous conical teeth on the premaxilla and dentary that are replaced with three or four large incisiform multicuspid teeth, that become unicuspid in ...

Enhanced Pollen Classification via Hybrid Neural Network With Attention Mechanism and View Separation: An Equatorial and Polar Approach

IEEE Access
Accurate classification of pollen grains is crucial for various fields, including ecology and food engineering. However, current approaches often face challenges due to limited data and the morphological variability of pollen grains.

Phenotypic characterization of naturalized swine breeds in Brazil, Uruguay and Colombia

Brazilian Archives of Biology and Technology, 2010
Morphometric data was collected on 859 naturalized swine in Brazil (Piau, Tatu, Nilo, Caruncho, Casco de Burro, Moura, Monteiro and Rabo de Peixe), Colombia (Criolla Zungo, Sanpedreño and Casco de Mula) and Uruguay (Mamellado), both on farm and in ...

Critical properties of the XXZ model with long-range interactions on the double chain

, 2006
The $XXZ$ model $(s = 1/2)$ in a transverse field on a double chain with a uniform long-range interaction among the $z$ components of the spins is considered.
