The velocity of gravitational waves [PDF]
Physics Letters A, 1999 We examine the propagation of gravitational waves in the new field theory of gravitation recently proposed by Novello-De Lorenci-Luciane (NDL). This examination is done on a solvable case corresponding to a spherically symmetric static configuration. We show that in NDL theory the velocity of gravitational waves is lower than light velocity.

Detection of gravitational waves by light perturbation
European Physical Journal C: Particles and Fields, 2021 Light undergoes perturbation as gravitational waves pass by. This is shown by solving Maxwell’s equations in a spacetime with gravitational waves; a solution exhibits a perturbation due to gravitational waves.

Diagrammatic Effective Field Theory Approach to Coalescing Binary Systems in General Relativity and Gravitational Waves Phenomenology [PDF]
, 2023 openIn this thesis we study the dynamics of a gravitationally bound binary system composed of two spinless compact objects, which could be black holes or neutron stars, in the post-Newtonian (PN) approximation scheme of general relativity.

Journal of High Energy PhysicsWe study the decays of B (s) mesons into light pseudoscalar mesons under the SU(3) flavour symmetry. Assuming exact SU(3) symmetry at the level of the amplitudes leads to a simple parametrisation.

3D Printing Innovations in Polymeric Porous and Patterned Architecture
Advanced Functional Materials, EarlyView.Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

European Physical Journal C: Particles and Fields, 2020 In the gravitational sector, we study the CPT violation and birefringence in gravitational waves. In presence of the CPT violation, a relative dephasing is generated between two circular polarization states of gravitational waves. This effect induces the

Advanced Materials, EarlyView.We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

QED factorization of two-body non-leptonic and semi-leptonic B to charm decays
Journal of High Energy Physics, 2021 The QCD×QED factorization is studied for two-body non-leptonic and semi-leptonic B decays with heavy-light final states. These non-leptonic decays, like B ¯ s 0 → D s + π − $$ {\overline{B}}_{(s)}^0\to {D}_{(s)}^{+}{\pi}^{-} $$ and B ¯ d 0 → D + K − $$ {\
