SEMINAR ANNOUNCEMENT
During the last week of June and the beginning of the first week of July a number of string theorists will be visiting Copenhagen: M. Douglas 22-28.6, I. Klebanov 24-28.6, L. Susskind 22.6-1.7, L. Thorlacius 22.6-4.7. The idea is to have a very informal meeting, with one or two seminars each day given by the people visiting Copenhagen and others. Details on the various seminars will be given later. A number of Nordic students will also be attending the meeting. If you are interested in participating, please contact Anna Maria Rey, e-mail: rey@nordita.dk.

COURSES / CONFERENCES / WORKSHOPS

Workshop on Fundamental Aspects of Applications of Single Electron Devices
24-26 July 1997, Hotel Frederiksdal, Lyngby, Denmark
A three day workshop on the physics of single electron devices is held in connection with the European SETamp project. The emphasis of the workshop will be on the understanding of the physical mechanisms that limits the applicability of the single electron devices. List of invited speakers: P. Joyez, Saclay, France; M. Keller, NIST, USA; A. Korotkov, Moscow, Russia; A.A. Odintsov, Delft University, The Netherlands; H. Schoeller, Karlsruhe, Germany.

Local organizing and scientific committee: Karsten Flensberg, Danish Institute of Fundamental Metrology, Hans D. Jensen, Danish Institute of Fundamental Metrology, Antti-Pekka Jauho, Mikroelektronik Centret, DTU, and Henrik Bruus, Niels Bohr Institute. List of topics: Influence of background charges, cotunneling, time-dependent properties, sources of noise, theoretical modeling, device types, cycle missing, quantum fluctuations, and photon assisted tunneling. Sponsors: EU commission and The Danish Natural Science Research Council.

Dynamics Biological Systems
Nordita, Copenhagen, 29-30 August 1997
To facilitate cross-disciplinary interaction between physics and biology we are planning a two-day workshop on ``Dynamics of Biological Systems", 29-30 August 1997. The workshop will cover areas in biology which may benefit from modelling. The common theme of the meeting will be the formulation of biology in terms of dynamical processes. In particular we intend to include dynamical aspects of mutating systems, evolutionary dynamics and various network systems (genetic, chemical and ecosystems). The meeting will consist of invited talks (each about 45 minutes) and a number of short presentations (each of about 10 minutes). Participants are encouraged to submit proposals for such short presentations and/or posters. For further information, contact John Hertz (e-mail: hertz@nordita.dk), Kim Sneppen (e-mail: sneppen@nordita.dk) or see website: http://www.nordita.dk/$\sim$hertz/opslag.html

COSMOLOGY: From COBE to Galaxy Formation
NORDITA, 2 - 5 December 1997
The conference ``Cosmology: from COBE to Galaxy Formation" will take place at NORDITA from 2 - 5 December this year. It is organised by Sasha Kashlinsky and sponsored by Nordita, TAC and NorFA.
It is planned to bring together around 70 researchers from various areas in cosmology to discuss the latest developments in the field from microwave background observations (past, current and future), through large-scale structure (observational and theoretical) to galaxy formation at high redshifts. A session will be devoted to astroparticle physics. Organizers: S. Kashlinsky (kash@nordita.dk) and J. Hjorth (jens@nordita.dk). Conference e-mail: cosmology@nordita.dk and website: http://www.nordita.dk/Conf/cosmology/
