Avalanche-like behavior in ciliary import

Avalanche-like behavior in ciliary import.

Cilia and flagella are microtubule-based organelles that protrude from the cell body. Ciliary assembly requires intraflagellar transport (IFT), a motile system that delivers cargo from the cell body to the flagellar tip for assembly. The process controlling injections of IFT proteins into the flagellar compartment is, therefore, crucial to ciliogenesis. Extensive biochemical and genetic analyse...

Modelling Avalanche in DES-Like Ciphers

In this paper, we examine the avalanche characteristics of private-key block ciphers constructed using a DES-like architecture. Avalanche is a desirable cryptographic property that is necessary to ensure that a small diierence between two plaintexts results in a seemingly random diierence between the two corresponding ciphertexts. In order to examine the behaviour of DES-like ciphers in relatio...

Noise Driven Avalanche Behavior in Subexcitable Media

The interaction of noise with a subexcitable chemical system gives rise to spatiotemporal behavior with novel statistical properties. Wave behavior in a photosensitive Belousov-Zhabotinsky reaction with imposed noise is monitored and statistically analyzed. Waves are initiated at sites where the accumulation of subthreshold perturbations induces local excitations, and waves propagate through th...

Intracellular calcium signals display an avalanche-like behavior over multiple lengthscales

Many natural phenomena display "self-organized criticality" (SOC), (Bak et al., 1987). This refers to spatially extended systems for which patterns of activity characterized by different lengthscales can occur with a probability density that follows a power law with pattern size. Differently from power laws at phase transitions, systems displaying SOC do not need the tuning of an external param...
