Born into the 1970s revolutionary movement for Black equality and self-determination, they have lived in the shadows of a promised land that was never attained. We join them as they continue to wrestle, 50 years later, with the dichotomy of their extraordinary childhoods: the enormous pride and love it gave them as members of the Black Panther family, and the booming loss they endured – of parents, of security, and of the hope for radical change that did not materialise.

you've heard of chemists in the 30's
are you prepared for chemists in the 1830's?
moreover, bunsen himself?

On the design of Compact Elastic Binary Trees (cebtree)
Those who often hear me discuss about my week-end projects have been accustomed to hearing about deuterium fusion (that's for another post),...

China kontrolliert den Großteil des weltweiten Angebots dieser kritischen Rohstoffe und hat kürzlich die Exportkontrollen verschärft, was den Zugang für europäische Länder weiter erschwert.

The complexity of deciding characteristic formulae modulo nested simulation
This paper studies the complexity of determining whether a formula in the modal logics characterizing the nested-simulation semantics is characteristic for some process, which is equivalent to determining whether the formula is satisfiable and prime. The main results are that the problem of determining whether a formula is prime in the modal logic characterizing the 2-nested-simulation preorder is CoNP-complete and is PSPACE-complete in the case of the n-nested-simulation preorder, when n>= 3. …

Properties of zero-determinant strategies in multichannel games
Controlling payoffs in repeated games is one of the important topics in control theory of multi-agent systems. Recently proposed zero-determinant strategies enable players to unilaterally enforce linear relations between payoffs. Furthermore, based on the mathematics of zero-determinant strategies, regional payoff control, in which payoffs are enforced into some feasible regions, has been discovered in social dilemma situations. More recently, theory of payoff control was extended to multichann…

With a bit of determination and some brain, Europe and China might be able to let Russia and the US cavort themselves into oblivion and establish a new bipolar world order for fun and profit.
