Avalanches along Takayama line (Toyama-Gihu)

Spectral statistics of global avalanches along granular piles

– In a seminal experiment, Jaeger et al. (Phys. Rev. Lett., 62 (1989) 40) measured the power spectrum of the velocity of avalanches along a granular pile in a rotating drum. Although their findings started an actively discussed debate on whether self-organized criticality rules granular avalanche dynamics, their experimental results have not been explained in theoretical detail yet. By the use ...

A short line segment squirms along a zigzag line

When a short straight line segment moves across a zigzag line and is viewed in one's peripheral vision, it appears to exhibit nonrigid squirming motion (the squirm effect). This phenomenon demonstrates that the form, orientation, and motion direction of a short line are influenced by those of a longer one when they are viewed in one's peripheral vision.

Growth of Analytic Functions Along a Line.

Let J(z) be regular and of exponential type less than wr in the half plane x _ 0, and let I Xn } be an increasing positive sequence of unit density such that Xn+1 -n _ 5 > 0. It is known that under suitable restrictions and with a suitable measure of growth, the growth of the sequence tf(Xn) determines the growth off(x) for real x > 0. I have established the following results. Let e(x) be a con...

Knowledge about Lights along a Line

In this article, we are going to talk about spatial situations. Every agent (human, camera etc.) and every proposition (lamp, object, etc.) are located in the space (here a line) and we express properties over a situation using standard epistemic logic language possibly extended with public announcements. We study links between validities of this geometrical version of epistemic logic and the s...
