Robustness of spatial patterns in buffered reaction-diffusion systems and its reciprocity with phase plasticity

2017-03-24T10:00:00-04:00

Author(s): Tetsuhiro S. Hatakeyama and Kunihiko Kaneko
The robustness of spatial patterns against perturbations is an indispensable property of developmental processes for organisms, which need to adapt to changing environments. Although specific mechanisms for this robustness have been extensively investigated, little is known about a general mechanism…

Breakdown of nonlinear elasticity in stress-controlled thermal amorphous solids

Author(s): Vladimir Dailidonis, Valery Ilyin, Itamar Procaccia, and Carmel A. B. Z. Shor
In recent work it was clarified that amorphous solids under strain control do not possess nonlinear elastic theory in the sense that the shear modulus exists but nonlinear moduli exhibit sample-to-sample fluctuations that grow without bound with the system size. More relevant, however, for experimen…

Author(s): Douglas A. Kurtze
Many car-following models of traffic flow admit the possibility of absolute stability, a situation in which uniform traffic flow at any spacing is linearly stable. Near the threshold of absolute stability, these models can often be reduced to a modified Korteweg-deVries (mKdV) equation plus small co…

Collisional model of energy dissipation in three-dimensional granular impact

2017-03-22T10:00:00-04:00

Author(s): Cacey Stevens Bester and Robert P. Behringer

This paper extends to three dimensions the collisional model for penetration of a granular medium by a solid object. The authors performed impact experiments with objects of different shapes in dry granular beds using high-speed imaging. The results show that the main drag force on objects colliding with a granular bed arises from perpendicular collisions with chains of granular particles.

Author(s): J. Roberto Romero-Arias, Valeria Hernández-Hernández, Mariana Benítez, Elena R. Alvarez-Buylla, and Rafael A. Barrio

In this paper, the authors explore the role of mechanical and chemical influences in morphogenesis, specifically, the emergence of cellular patterns in the growth of plant roots. Their model couples cell division to the local concentration of the hormone auxin and physical elastic forces, and is able to reproduce experimental observations in real roots.
