Families of graphs with maximum nullity equal to zero forcing number
Special Matrices, 2018 The maximum nullity of a simple graph G, denoted M(G), is the largest possible nullity over all symmetric real matrices whose ijth entry is nonzero exactly when fi, jg is an edge in G for i =6 j, and the iith entry is any real number.

A GCM study of the response of the atmospheric water cycle of West Africa and the Atlantic to Saharan dust radiative forcing [PDF]
Annales Geophysicae, 2009 The responses of the atmospheric water cycle and climate of West Africa and the Atlantic to radiative forcing of Saharan dust are studied using the NASA finite volume general circulation model (fvGCM), coupled to a mixed layer ocean.

On the origin and pathway of the saline inflow to the Nordic Seas: insights from models [PDF]
, 2001 The behaviours of three high-resolution ocean circulation models of the North Atlantic, differing chiefly in their description of the vertical coordinate, are investigated in order to elucidate the routes and mechanisms by which saline water masses of ...

Observation and simulation of wave breaking in the southern hemispheric stratosphere during VORCORE [PDF]
Annales Geophysicae, 2013 An interesting occurrence of a Rossby wave breaking event observed during the VORCORE experiment is presented and explained. Twenty-seven balloons were launched inside the Antarctic polar vortex.

Weak Force Stalls Protrusion at the Leading Edge of the Lamellipodium [PDF]
Biophysical Journal, 2006 Protrusion, the first step of cell migration, is driven by actin polymerization coupled to adhesion at the cell's leading edge. Polymerization and adhesive forces have been estimated, but the net protrusion force has not been measured accurately. We arrest the leading edge of a moving fish keratocyte with a hydrodynamic load generated by a fluid flow ...
