Ms. 930a, Nr. 13, Bl. 35r-[36v] August Hennings. Brief an Garlieb H. Merkel, Ploen, den 20. Dece[mber] 1798 Autora rokraksts / Autograph, vācu val. / Deutsch [3] lpp. / S. Attēlu numuri / Bildnummern: 930a-013-1, 930a-013-2, 930a-013-3 Hennings, der dänische Amtmann in Plön und Bekannte des dänischen Ministers Schimmelmann, schreibt in seiner Funktion als Herausgeber der Zeitschrift „Genius der Zeit“ an Merkel. Er kündigt an, einen Aufsatz zu drucken, in dem Merkel Partei für seinen Schriftstellerkollegen Johann(es) Falk ergreift, worum ihn dieser in einem anderen Brief gebeten hat (vgl. Ms. 930a-012). Merkels Aufsatz soll in der Februarausgabe 1799 erscheinen. Der Aufsatz sowie der hier üb…
Radio k-Labelings for Cartesian Products of Graphs
2005
International audience; Frequency planning consists in allocating frequencies to the transmitters of a cellular network so as to ensure that no pair of transmitters interfere. We study the problem of reducing interference by modeling this by a radio k-labeling problem on graphs: For a graph G and an integer k ≥ 1, a radio k-labeling of G is an assignment f of non negative integers to the vertices of G such that |f(x)−f(y)| ≥ k+1−dG(x,y), for any two vertices x and y, where dG(x,y) is the distance between x and y in G. The radio k-chromatic number is the minimum of max{f(x)−f(y):x,y ∈ V(G)} over all radio k-labelings f of G. In this paper we present the radio k-labeling for the Cartesian pro…
Robust dynamic cooperative games
2009
Classical cooperative game theory is no longer a suitable tool for those situations where the values of coalitions are not known with certainty. Recent works address situations where the values of coalitions are modelled by random variables. In this work we still consider the values of coalitions as uncertain, but model them as unknown but bounded disturbances. We do not focus on solving a specific game, but rather consider a family of games described by a polyhedron: each point in the polyhedron is a vector of coalitions’ values and corresponds to a specific game. We consider a dynamic context where while we know with certainty the average value of each coalition on the long run, at each t…
Joziknipholones A and B: The First Dimeric Phenylanthraquinones, from the Roots ofBulbine frutescens
2007
From the roots of the African plant Bulbine frutescens (Asphodelaceae), two unprecedented novel dimeric phenylanthraquinones, named joziknipholones A and B, possessing axial and centrochirality, were isolated, together with six known compounds. Structural elucidation of the new metabolites was achieved by spectroscopic and chiroptical methods, by reductive cleavage of the central bond between the monomeric phenylanthraquinone and -anthrone portions with sodium dithionite, and by quantum chemical CD calculations. Based on the recently revised absolute axial configuration of the parent phenylanthraquinones, knipholone and knipholone anthrone, the new dimers were attributed to possess the P-co…
