Force dipoles and stable local defects on fluid vesicles
, 2013 An exact description is provided of an almost spherical fluid vesicle with a fixed area and a fixed enclosed volume locally deformed by external normal forces bringing two nearby points on the surface together symmetrically.

Spiral Waves in Driven Dusty Plasma Medium: Generalized Hydrodynamic Fluid Description
, 2017 Spiral waves are observed in many natural phenomena. They have been extensively represented by the mathematical FitzHugh-Nagumo (FHN) model [Barkley et al., Phys. Rev. A 42, 2489 (1990)] of excitable media.

Shear stress fluctuations in the granular liquid and solid phases
, 2005 We report on experimentally observed shear stress fluctuations in both granular solid and fluid states, showing that they are non-Gaussian at low shear rates, reflecting the predominance of correlated structures (force chains) in the solidlike phase ...

Atomic force microscopy (AFM) study of thick lamellar stacks of phospholipid bilayers
, 2007 We report an Atomic Force Microscopy (AFM) study on thick multi lamellar stacks of approx. 10 mum thickness (about 1500 stacked membranes) of DMPC (1,2-dimyristoyl-sn-glycero-3-phoshatidylcholine) deposited on silicon wafers.
