Nordic Projects and Corresponding Fellowsships 2001

NORDITA announces the availability of funding for Nordic projects and corresponding fellowships in 2001. The purpose and rules as well as application forms for these schemes are given on www.nordita.dk, under "Positions and Projects", and may also be obtained from nordita@nordita.dk. The deadline for application is 1 October 2000, with a decision by the NORDITA board expected in October 2000.

Lars Melwyn Jensen
NORDITA's New Computer Manager
Lars Melwyn Jensen took up his position as new computer manager at NORDITA on 1 June 2000.
After undergraduate studies at the University of Copenhagen, he has recently completed his licentiate degree at Umeå University on "the dynamic critical properties of superfluids and superconductors". During his time in Umeå, he also worked as assistant computer system administrator.

Tomas Bohr: New NORDITA Corresponding Fellow

NORDITA warmly welcomes Tomas Bohr as new corresponding fellow. T. Bohr received his Ph.D. in 1983 on the subject of "Elementary Excitations in Phase Transitions". After his postdoc years at the Laboratory of Atomic and Solid State Physics, Cornell University, he was assistant professor at the H.C. Ørsted Institute (1985-87), the Niels Bohr Institute (1987-90), and was appointed a Hallas-Møller Lektor (funded by the Novo-Nordisk Foundation) at the Niels Bohr Institute from 1990-95 . He is co-founder of the "Center for Chaos and Turbulence Studies", which was established in 1993 with funding from the Danish NSF. Presently he is Professor of physics at the "Physics Department" at the Danish Technical University, Copenhagen. His main interests are: Hydrodynamics (especially free surface flows), turbulence, chaos in extended systems and non-equilibrium statistical mechanics. E-mail: tbohr@nbivms.nbi.dk.

Board Meeting
Nordita's Board will meet on 27 October in Copenhagen.

Genetic Intelligence of Bacteriophage
NORDITA-Workshop
24 -26 August 2000

The topic of this workshop is the mechanisms for genetic control employed by bacteriophages, which are viruses that infect bacteria. Genetic control and how to model it will probably become a major field soon. The motivation for this workshop is to obtain a window into biology by studying very simple "organisms".

The meeting will discus:   genetic switches and decision circuits in bacteriophages, with the aim of developing a quantitative understanding of molecular decision processes, including the possibility for spontaneous failures of maintaining decisions.

The meeting is interdisciplinary; researchers and students from both physics and biology will participate. We expect about 10-15 speakers and a total attendance of 30-40 people. The meeting will start on the morning of August 24 and end on the afternoon of August 26.

For registration and hotel reservations, please contact Ellen Pedersen (pedersen@nordita.dk) by email.
For more information on the workshop, see web page http://www.nordita.dk/Adm/Meetings/GIP2000/

Organizing committee: Sankar Adhya (NCI, Bethesda), Stanley Brown (Copenhagen University), John Hertz and Kim Sneppen.

Problems of the Cosmological Constant and Vacuum Energy
24 - 26 August 2000, Copenhagen

A conference on this subject will be held in Copenhagen on August 24-26 2000. The conference, organized and financed by Nordita and TAC, is aimed at covering the following topics:

1. Observational and theoretical arguments in favor of a non-vanishing cosmological constant.
2. Phenomenology of an accelerating universe.
3. The issue of huge vacuum energy in quantum physics.

The local organization committee consists of Prof. Alexandre Dolgov (Ferrara), Prof. Axel Brandenburg (NORDITA) and assistant professors Kimmo Kainulainen, Rachid Ouyed and Steen Hannestad (NORDITA).
For more information, see web page http://www.nordita.dk/~kainulai/LC/LambdaCosmo.html
