Multiplicity of solutions for non-homogeneous Neumann problems in Orlicz-Sobolev spaces

open access: yesElectronic Journal of Differential Equations, 2017
This article concerns the existence of non-trivial weak solutions for a class of non-homogeneous Neumann problems. The approach is through variational methods and critical point theory in Orlicz-Sobolev spaces.

Sudan at War With Itself: Civilian Devastation in the Civil War

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT A civil war is raging in Sudan between the Sudan Armed Forces (SAF) and the Rapid Support Forces (RSF) along with militia groups. Beginning on April 15, 2023, and continuing at least to this writing (October 15, 2025), civilian noncombatants have been subjected to bombings, beatings, torture, shootings, rape, and murder on a large scale. Since

Carbonate sedimentology: An evolved discipline

open access: yesThe Depositional Record, EarlyView.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis

open access: yesThe Depositional Record, EarlyView.
The paleo‐hydrology of the Sorbas Basin (SE Spain) and the wider Mediterranean region during the deposition of the Primary Lower Gypsum (PLG) stage of the Messinian Salinity Crisis, from ~5.97 to ~5.60 Ma, was affected by tectonics, precession‐forced climate oscillations, and eustatic sea‐level change.

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

Existence of positive solutions for superlinear p-Laplacian equations

open access: yesElectronic Journal of Differential Equations, 2015
We obtain a positive solution for a superlinear p-Laplacian equations with the Dirichlet boundary-value conditions. Our main tool is a variation of the mountain pass theorem.
