Towards a holographic theory of cosmology -- threads in a tapestry [PDF]
, 2013 In this Essay we address several fundamental issues in cosmology: What is the nature of dark energy and dark matter? Why is the dark sector so different from ordinary matter?

Investigation of Uplift force effects on Seismic Damage of Concrete Gravity Dam in the Near-Fault and Far-Fault Ground Motions:Case Study Shafaroud Dam [PDF]
Journal of Structural and Construction Engineering, 2019 Uplift force has significant role on dynamic response of concrete gravity dams and also seismic response of dams in near field motion can be considerably different from those observed in the far field and the near –fault ground motions can cause ...

Cosmic Strings in a Braneworld Theory with Metastable Gravitons [PDF]
, 2001 If the graviton possesses an arbitrarily small (but nonvanishing) mass, perturbation theory implies that cosmic strings have a nonzero Newtonian potential. Nevertheless in Einstein gravity, where the graviton is strictly massless, the Newtonian potential

Structural assessment of gravity dams by means of a semi-discrete approach [PDF]
, 2018 A new numerical model for the structural assessment of gravity dams by means of a semidiscrete approach is proposed. Gravity dams are massive structures, which their stability depends on the gravity loads applied into the structure.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
