Dyson Pairs and Zero-Mass Black Holes [PDF]
, 1996 It has been argued by Dyson in the context of QED in flat spacetime that perturbative expansions in powers of the electric charge e cannot be convergent because if e is purely imaginary then the vacuum should be unstable to the production of charged ...

Ecological Entomology, Volume 51, Issue 3, Page 502-516, June 2026.First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Strut and tie modeling for RC short beams with corroded stirrups
Latin American Journal of Solids and StructuresCorrosion of steel reinforcement is one of the major problems that shorten the service life of reinforced concrete (RC) structures. Steel stirrups, due to their location as an outer reinforcement, are more susceptible to corrosion problems and damage ...

Modified Softened Strut and Tie Model for Concrete Deep Beams
Journal of Engineering and Sustainable Development, 2012 A modified softened strut-and-tie model (MSST) for determining the shear strength of reinforced concrete deep beams is proposed in this paper. It is a simplified analytical model and several improvements have been made.

Analysis of the structural behavior of beam-column joints in reinforced concrete frames considering bending towards the reduced side of the cross section [PDF]
Revista IBRACON de Estruturas e MateriaisThe beam-column joints are called discontinuous regions and, therefore, could be designed by the strut and tie method. In beam-column joints where the bending plane coincides with the column's smaller dimension, the bending moments associated with the ...
