School of Chemistry at Tel-Aviv UniversityOrganizer Department of Molecular Chemistry and Materials ScienceContact Abstract Show full text abstract about Salalens are tetradentate dianionic sequential {ONN'O}-...» Salalens are tetradentate dianionic sequential {ONN'O}-type ligands that lead to octahedral complexes of group 4 metals of the type [{ONN'O}MX2] of fac-mer geometry and C1-symmetry. We have recently developed an efficient methodology for the synthesis of Salalen ligands that enables the fine-tuning of steric and electronic parameters. We found that several titanium complexes of these ligands led to highly active catalysts for polymerization of alpha-olefins, and, most importantly, to polypropylene with very high isotacticities, reaching [mmmm] > 99.6% and melting transitions of up to 169.9 °C, which is unprecedented, to our knowledge. In this presentation we will describe the design principles that have led to this development, and, as time allows, the development of other homogeneous catalysts for stereoregular polymerization. -

A minimal dynamical model that reproduces the statistical features of experimental trajectories, is deduced from trajectory data. This model extends the cell-type specific models derived for mammalian cells a few years ago.

Many studies a...» What is the nature of neural representations? Many studies addressing this question searched for single neurons with easily interpretable activity profiles, even though all cognitive tasks require the joint activity of a large population of neurons. In this talk I highlight the "other" neurons, and show that when considered as a population these "disordered" neurons can support behavioral tasks - and are even a better substrate for flexible tasks than "ordered" neurons are. Using a combination of data analysis from the labs of Ranulfo Romo and Earl Miller with numerical simulations and analytical calculations I will try to make all of these notions and statements more rigorous and precise. -

More information Time 11:15 - 12:30Location Edna and K.B. Weissman Building of Physical SciencesLecturer Bjorn Hof
MPI GettingenOrganizer Faculty of PhysicsContact Abstract Show full text abstract about Shear flows undergo a sudden transition from laminar to turb...» Shear flows undergo a sudden transition from laminar to turbulent motion as the velocity increases, and the onset of turbulence radically changes transport efficiency and mixing properties. Even for the well-studied case of pipe flow, it has not been possible to determine at what Reynolds number the motion will be either persistently turbulent or ultimately laminar.
We show that in pipes, turbulence that is transient at low Reynolds numbers becomes sustained at a critical point via a non-equilibrium phase transition. Through extensive experiments and computer simulations, we were able to identify and characterize the processes ultimately responsible for sustaining turbulence. In contrast to the classical Landau-Ruelle-Takens view that turbulence arises from an increase in the temporal complexity of fluid motion, here, spatial proliferation of chaotic domains is the decisive process and intrinsic to the nature of fluid turbulence.
