Dynamic equilibrium condition (DEC) is described as a steady-state condition at which the normal wear rate in a machine causes no net gain or loss of particles. The concept of DEC of particles is ...

Soft matters maintain their structures via weak interactions, such as Van der Waals, capillary, hydrogen bonds etc. The entropy plays a key role in the ordering of this kind of materials. They behave ...

We show that hard, convex, lithographic, prismatic kite platelets, each having three 72° vertices and one 144° vertex, preferentially form a disordered and arrested 2D glass when concentrated ...

This is a preview. Log in through your library . Abstract We consider incompressible 2d Navier-Stokes equations in the whole plane with external nonconservative forces fields. The initial data and ...

Burning hydrocarbon fuels produces nano-sized soot particles and Polycyclic Aromatic Hydrocarbons (PAH) - harmful emissions that impact our environment. The carbon-made particles make up 70% of our ...

The behavior of crowds at heavy metal concerts is surely a topic close to the hearts of many readers of the Physics arXiv Blog. In these crowds, fans often form circles called mosh pits and then run ...
