Modelling, Analysis and Simulation Spontaneous branching of anode-directed streamers between Planar electrodes

Non-ionized media subje t to strong elds an be ome lo ally ionized by penetration of nger-shaped streamers. We study negative streamers between planar ele trodes in a simple deterministi ontinuum approximation. We observe that for suÆ iently large elds, the streamer tip an split. This happens lose to Firsov's limit of \ideal ondu tivity". Qualitatively the tip splitting is due to a Lapla ian in...

" Understanding Cryptography "

Yet another introductory book on cryptography!? This is what most people from the community might think, when they first glimpse at the present book by Christof Paar and Jan Pelzl. And that is what the book entitled Understanding Cryptography really is about. It is a textbook mainly targeted to undergraduate students as a very first course in cryptography. Still, when having a closer second loo...

Co(II) AND Cu(II) - PROMOTED BASE HYDROLYSIS OF 2-CYANO-l, lO-PHENANTHROLINE

Co(II) and Cu(II) promoted base hydrolysis of 2-cyano, 1, lO-phenanthroline was studied. At 298.2°K, Cu(II) reaction is more efficient (by a factor of 20) than either Co(ll) and its analogues Ni(II) in promoting base hydrolysis.

Complement receptor 2/CD21- human naive B cells contain mostly autoreactive unresponsive clones.

Complement receptor 2-negative (CR2/CD21(-)) B cells have been found enriched in patients with autoimmune diseases and in common variable immunodeficiency (CVID) patients who are prone to autoimmunity. However, the physiology of CD21(-/lo) B cells remains poorly characterized. We found that some rheumatoid arthritis (RA) patients also display an increased frequency of CD21(-/lo) B cells in thei...
