Roland Brandt studied Biochemistry and Philosophy at the University of Tübingen and the Free University of Berlin in Germany. He performed his doctoral work at the Max-Planck-Institute of Molecular Genetics, Berlin, after which he continued as a postdoctoral research fellow at the Center for Neurologic Diseases (CND), Harvard Medical School, Boston (USA). By returning to Germany, he became an i...

We prove the conjecture of Abbott and Katchalski that for every m ≥ 2 there is a positive constant λm such that S(K d mn) ≥ λmnS(K m ) where S(K m) is the length of the longest snake (cycle without chords) in the cartesian product K m of d copies of the complete graph Km. As a corollary, we conclude that for any finite set P of primes there is a constant c = c(P ) > 0 such that S(K n) ≥ cnd−1 f...

In the past, Computer Network Defense (CND) intended to be minimally intrusive to the other requirements of IT development, business, and operations. This paper outlines how different security paradigms have failed to become effective defense approaches, and what the root cause of the current situation is. Based on these observations, a different point of view is proposed: acknowledging the inh...

Utilizing the Atacama Large Millimeter/submillimeter Array (ALMA), we present CS line maps in five rotational lines ($J_{\rm u}=7, 5, 4, 3, 2$) toward circumnuclear disk (CND) and streamers of Galactic Center. Our primary goal is to resolve compact structures within CND streamers, order understand stability conditions molecular cores vicinity supermassive black hole (SMBH) Sgr A*. data provide ...

Interstellar molecular clouds play an essential role in the Universe. Such clouds are invoked for the production and destruction of stars, galaxies and gas and also for energy transport in galaxies. The Galaxy, or the Milky Way, is a large spiral galaxy, with a central bar structure, that harbours a few hundred billion stars and large amounts of gas and dust. At the centre of the Galaxy, a 4 mi...

The accretion rates needed to fuel the central black hole in a galaxy can be achieved via viscous torques thick disks and rings, which resolved by millimetre interferometry within inner ~20pc of active NGC1068 at comparable scales sensitivity single dish observations Circumnuclear Disk (CND) Galactic Center. To interpret these regions determine physical properties their gas distribution, we pre...
