The multiphase Darcy model used to represent two-phase immiscible displacement flow within porous media is critically examined, and the principle assumptions and limitations discussed. We identify some of the main problems which require bet...

Abstract Critical gravity is a quadratic curvature gravity in four dimensions which is ghost-free around the AdS background. Constructing a Vaidya-type exact solution, we show that the area of a black hole defined by a future outer trapping...

The standard procedure for computing scalar multi-loop Feynman integrals consists in reducing them to a basis of so-called master integrals, derive differential equations in the external invariants satisfied by the latter and, finally, try ...

We have formulated a new model for collisions with nuclei, called Angantyr, which is now included in PYTHIA8 event generator. The model is inspired by the old Fritiof model, but also includes effects of hard partonic interactions. It uses a...

We construct statistical ensembles of modular Boolean networks that are constrained to lie at the critical line between frozen and chaotic dynamic regimes. The ensembles are maximally random given the imposed constraints, and thus represent...

We study the decay B¯→Xsγ in Randall–Sundrum models with an IR-localised bulk Higgs. The two models under consideration are a minimal model and a model with a custodial protection mechanism. We include the effects of tree- and one-loop diag...

Abstract In a model for leptogenesis based on spontaneous breaking of Lorentz and $$\mathcal {CPT}$$ CPT symmetry [1–3], we examine the consistency of using the approximation of plane-wave solutions for a free spin-$$\frac{1}{2}$$ 12 Dirac ...
