Damage modeling of CO2 injection well interfaces under coupled thermal, hydraulic and mechanical behavior

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper presents an investigation of CO2 injection well damage evolution considering different injection temperatures and the presence of a pre‐existing defect. The main outcome is that the accurate prediction of well leakage risk requires characteristics such as initial defects to be understood and represented in any modeling efforts. Abstract This

Multiplicity theorems for semipositone p-Laplacian problems

open access: yesElectronic Journal of Differential Equations, 2011
In this article, we study the existence of solutions for the semipositone p-Laplacian problems. Under a subliner behavior at infinity, using degree theoretic arguments based on the degree map for operators of type (S)_+, we prove the existence of at ...

Identification of neural crest and melanoma cancer cell invasion and migration genes using high‐throughput screening and deep attention networks

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Cell migration and invasion are well‐coordinated in development and disease but remain poorly understood. We previously showed that the neural crest (NC) cell migratory wavefront shares a 45‐gene panel with other cell invasion phenomena.

Blow-up for p-Laplacian parabolic equations

open access: yesElectronic Journal of Differential Equations, 2003
In this article we give a complete picture of the blow-up criteria for weak solutions of the Dirichlet problem $$ u_t= abla(| abla u|^{p-2} abla u)+lambda |u|^{q-2}u,quad hbox{in } Omega_T, $$ where $p>1$.

Differentiating between F and OH Ligands in Homologous Gold(III) Complexes beyond X‐Ray Crystallography

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A subtle hydrogen‐bonding lock enables the unequivocal structural differentiation between fluoride and hydroxide in the unusual couple of homologous organogold(III) complexes [PPh4][(CF3)3AuF] and [PPh4][(CF3)3Au(OH)] (see adjacent figure). The homologous fluoride and hydroxide complexes of gold(III) [PPh4][(CF3)3AuX] [X = F (1), OH (2)] have been ...

A Force‐Based Beam‐Column Element With Selective Gradient‐Inelasticity for Softening Materials in 3‐Dimensional Nonlinear Analysis

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Fiber‐based beam‐column elements featuring an effective material constitutive law with softening can capture the degrading response of structural members under extreme loading. However, these elements exhibit strain localization and mesh divergence, which impedes their accuracy.

Steklov problems involving the p(x)-Laplacian

open access: yesElectronic Journal of Differential Equations, 2014
Under suitable assumptions on the potential of the nonlinearity, we study the existence and multiplicity of solutions for a Steklov problem involving the p(x)-Laplacian. Our approach is based on variational methods.

Zero‐DAGNet: A Domain‐Adversarial Graph Network Integrated With POCO for Cyber‐Physical Security in Smart Grid

open access: yesEnergy Science &Engineering, EarlyView.
Proposed CPS for smart grid. ABSTRACT Smarter grids depend on Cyber‐Physical Systems (CPS) to merge physical energy distribution networks with computational intelligence, because these systems optimize reliability and sustainability and power delivery efficiency.
