ABSTRACT It has been contended that the Principle of Sufficient Reason (PSR) implies necessitarianism—that is, the view that everything occurs out of necessity. Discussing a well‐known argument for this claim developed by contemporary metaphysicians, I show that Ibn Sīnā has anticipated a counterpart of this argument, and that is precisely why he is ...

Comments on minitwistors and the celestial supersphere

Nuclear Physics B
Continuing our program of deriving aspects of celestial holography from string theory, we extend the Roiban-Spradlin-Volovich-Witten (RSVW) formalism to celestial amplitudes. We reformulate the tree-level maximally-helicity-violating (MHV) celestial leaf

International Cocoa Trading Arrangements Between Industrialised and Developing Countries 1951–1999: A Structural Gravity Analysis

The World Economy, EarlyView.
ABSTRACT Using a state‐of‐the‐art structural gravity model, we investigate the impact of various (post‐)colonial cocoa trading arrangements on the cocoa trade between developing cocoa producer countries and rich industrial cocoa consumer nations in the time period 1951–1999. We find that in particular the trading arrangements of the European (Economic)

No Degree, No Lab, No Borders: An Independent Researcher's Journey From Yemen to Global Science

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract I grew up in Yemen with a dream to study space, but my country had no astronomy programs, no universities for astrophysics, and soon, no stable peace. This Perspective is a personal and systemic account of how I pursued planetary science from a conflict zone—with no smartphone, no home internet, no supervisor, and no institutional backing.

Additional PAX3 Variants for Dominant Blue Eyes in Cats

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Since the recent publication of the first feline variant of the PAX3 (Paired Box 3) gene associated with blue eyes and minimal white spotting (DBE, Dominant Blue Eyes), three further variants of PAX3 have been reported in felines. However, these four variants do not account for all the different feline lines that exhibit DBE.

Eikonal amplitudes on the celestial sphere

Journal of High Energy Physics
Celestial scattering amplitudes for massless particles are Mellin transforms of momentum-space scattering amplitudes with respect to the energies of the external particles, and behave as conformal correlators on the celestial sphere.
