Collective Charge Excitations below the Metal-to-Insulator Transition in BaVS3

The charge response in the barium vanadium sulfide (BaVS3) single crystals is characterized by dc resistivity and low frequency dielectric spectroscopy. A broad relaxation mode in MHz range with huge dielectric constant ~= 10^6 emerges at the metal-to-insulator phase transition TMI ~= 67 K, weakens with lowering temperature and eventually levels off below the magnetic transition Tchi ~= 30 K. The mean relaxation time is thermally activated in a manner similar to the dc resistivity. These features are interpreted as signatures of the collective charge excitations characteristic for the orbital ordering that gradually develops below TMI and stabilizes at long-range scale below Tchi.Comment: 6 pages, 3 figures, submitted to PR

Professor Ivan Damjanov, the Third Recipient of Tomas Kent Award from the Group for Research in Pathology Education

The Group for Research in Pathology Education (GRIPE) was founded in 1971 by Tom Kent, M.D. of the University of Iowa as an organization devoted to promoting excellence in teaching pathology to medical students. A few years ago, the Executive Board of GRIPE decided to recognize the pioneering work of Dr. Kent by giving an award in his name (for details see http://peir.path.uab.edu/griper). This prestigious award was established to formally recognize outstanding academic pathologists for their lifetime contributions to the field of pathology education. The first recipient of the Tom Kent Award was Dr Stanley L. Robbins, Boston University, Boston, Massachusetts, author of the leading textbook of pathology in the United States (USA), widely used throughout the world. The second recipient was Dr Emanuel Rubin, Thomas Jefferson University, Philadelphia, Pennsylvania, the author of the innovative pathology textbook, in which he has pioneered the use of conceptual color drawings, diagrams and algorithms in the teaching of pathology. The third recipient of the Tom Kent Award is Dr Ivan Damjanov, Professor of Pathology, The University of Kansas, Kansas City, Kansas. Since Ivan Damjanov is a graduate of the University of Zagreb, we were pleased to accept the invitation of Dr. Matko Marusic, Editor-in-Chief of the Croatian Medical Journal, and briefly outline the contributions of Ivan Damjanov to pathology practice, research and education, both in the USA and Croatia

Past imperfect continuous: remembering Serbia’s 1915 retreat one hundred years later

This dissertation examines how the Serbs as a nation deal with the past through the prism of the 1915 Serbian Army retreat across Montenegro and Albania in the wake of the invasion of Serbia in October 1915. We investigate the remembrance of this iconic event as a symptom of Serbian mythologized self-perception. The Retreat today is a canonised memory symbolising Serbian heroism and sacrifice. The First World War and the Retreat are experienced as specific and personal. Any attempted introduction of alternative views of the Serbian role in the First World War are rejected as hostile revisionism. The Serbian government has used the centenary commemorations to distract the Serbian public from the more recent unexamined past — Serbia’s role in the wars of the Yugoslav succession of the 1990s. This commemorative opportunism has been termed in the thesis as historical frame switching —framing current political events within arguably irrelevant historical contexts mostly in order to present an image of biased and unjust treatment of Serbs by the West. Further, politically loaded commemorations are analysed alongside grassroot events and ceremonies that memorialise the War and the Retreat. The latter are recognised as fictive kinships of remembrance, as previously characterised by Jay Winter. Political Culture and National Identit
