Scalar 1-loop Feynman integrals as meromorphic functions in space-time dimension d

Khiem Hong Phan, Tord Riemann

The long-standing problem of representing the general massive one-loop Feynman integral as a meromorphic function of the space-time dimension has been solved for the basis of s…

Universality of the amplitude shift in fast two-pulse collisions in weakly perturbed linear physical systems

Quan M. Nguyen, Toan T. Huynh, Avner Peleg

We demonstrate that the amplitude shifts in fast two-pulse collisions in perturbed linear physical systems with weak nonlinear dissipation exhibit universal soliton-like behavior.…

On free subgroups in maximal subgroups of skew linear groups

Bui Xuan Hai, Huynh Viet Khanh

The study of the existence of free groups in skew linear groups have been begun since the last decades of the 20-th century. The starting point is the theorem of Tits (1972), now o…

Simulation of the impregnation in the porous media by the Self- organized Gradient Percolation method

Anh Khoa Nguyen, Eric Blond, Thomas Sayet +3

Many processes can correspond to reactive impregnation in porous solids. These processes are usually numerically computed by classical methods like finite element method, finite vo…

Collision-induced amplitude dynamics of pulses in linear waveguides with the generic nonlinear loss

Quan M. Nguyen

We study the effects of the generic weak nonlinear loss on fast two-pulse interactions in linear waveguides. The colliding pulses are described by a system of coupled Schrödinger e…

Robust Anomaly-Based Ship Proposals Detection from Pan-sharpened High-Resolution Satellite Image

Viet Hung Luu, Nguyen Hoang Hoa Luong, Quang Hung Bui +1

Pre-screening of ship proposals is now employed by top ship detectors to avoid exhaustive search across image. In very high resolution (VHR) optical image, ships appeared as a clus…
