Sink versus tilt penetration into shaken dry granular matter: The role of the foundation
L. Alonso-Llanes, G. Sánchez-Colina, A J Batista-Leyva +3
We study the behavior of cylindrical objects as they sink into a drygranular bed fluidized due to lateral oscillations. Somewhat unexpectedly, we have found that, within a large ra…
Experiments in the penetration of cuboid intruders near walls into granular matter
M. Espinosa, L. Alonso-LLanes, R. Herrero +1
When an object penetrates into granular matter near a boundary, it experiences a horizontal repulsion due to the intruder-grain-wall interaction. Here we show experimentally that a…
Guerrilla Science: creating scientific instruments in `high tropicallity' conditions
Ernesto Altshuler
The 1980s was a flourishing time for Cuban physics, with various achievements ranging from the design of several experiments to be performed by a Cuban cosmonaut in 1980, to the sy…
Intruders cooperatively interact with a wall into granular matter
M. Espinosa, V. L. Díaz, A. Serrano +1
When a cylindrical object penetrates granular matter near a vertical boundary, it experiences two effects: its center of mass moves horizontally away from the wall, and it rotates…
Protecting others vs. protecting yourself against ballistic droplets: Quantification by stain patterns
V. Márquez-Alvarez, J. Amigó-Vera, A. Rivera +2
It is often accepted a priori that a face mask worn by an infected subject is effective to avoid the spreading of a respiratory disease, while a healthy person is not necessarily w…
Design of an Externally Driven Current Cloak
A. S. García-Gordillo, E. Altshuler
An inhomogeneity into a conductive matrix deforms the flow pattern of an applied electric current. A usual current cloak can be defined as a permanent modification of the matrix pr…
