England's Fission Quest

FISSION FRAGMENT ANGULAR ANISOTROPIES AND INERTIA PARAMETERS

An analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. Theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. The nuclear moment of inertia extracted from the model calculations are compared with their est...

How Fission Yeast Fission in the Middle

In fission yeast, we propose that the division plane may be positioned by the position of the premitotic nucleus, perhaps by a signal emanating from the nucleus. Gene products involved in the assembly of the ring and its temporal and spatial controls are beginning to be characterized. Some of these, such as mid1p, may be involved in signals that position the division site. In animal cells, the ...

Silence as the Ultimate Fulfillment of the Philosophical Quest

The Quest for Uncertainty

The question of how to represent and process uncertainty is of fundamental importance to the scientific process, but also in everyday life. Currently there exist a lot of different calculi for managing uncertainty, each having its own advantages and disadvantages. Especially, almost all are defining the domain and structure of uncertainty values a priori, e.g., one real number, two real numbers...

Ongoing quest for QWERTY∗

First, we replicate the remarkable result of Hossain & Morgan (AER 2009), in which subjects in an experimental market tip almost perfectly to the superior platform even if an inferior platform enjoys initial monopoly. Next, we show that this result disappear when seemingly innocent increases in out-of-equilibrium payoffs are introduced. The inflated payoffs do not alter payoffor risk-dominance ...
