Agile project management capability enhances sustainable performance through the sequential mediation of agile leadership and strategic agility

Abstract Organizations face increasing pressure to achieve sustainable performance while remaining competitive in volatile environments. Although agility is widely recognized as being associated with organizational responsiveness, limited research explains how agile project manag...

Probing dark matter and phantom field effects on neutrino oscillations around black holes

Abstract This study investigates how dark matter in the background of the phantom field (DMPF) near a black hole influences neutrino flavor oscillations using a two-flavor model. It is found that gravitational effects are cancelled for radially moving neutrinos, causing the oscil...

Circular-orbit dynamics and QPO constraints in static Einstein–scalar–Gauss–Bonnet black holes

Abstract Einstein–scalar–Gauss–Bonnet (EsGB) gravity provides a physically motivated framework for testing strong-field deviations from the Schwarzschild geometry through scalar hair. We study neutral-particle circular motion and high-frequency quasi-periodic oscillations (HF-QPO...
