Because of the computational complexity of such evaluation, it is believed that human and animal brains use a range of shortcuts to simplify or approximate it. I review behavioral and neural evidence that humans rationally trade off exact and approximate evaluation in such sequential decision making. This research offers a new perspective on healthy behaviors, like habits, and pathological ones, like compulsion, which are both viewed as approximate evaluations that fail to incorporate experiences relevant to a decision and instead rely on inappropriate or out-of-date evaluations. I also present new theoretical and experimental work that aims to address the positive counterpart to such neglect: which particular events are considered, in which circumstances, to support choice. This brings the reach of the framework to many new phenomena, including pre-computation for future choices, nonlocal activity in the hippocampal place system, consolidation during sleep, and a new range of disordered symptoms such as craving, hallucinations, and rumination.

The experiments aim at maximizing the control over the junction properties and probe conductances, forces, shot-noise, and the emission of photons. We are particularly interested in molecules that exhibit switching behaviour of, e.g., their conformations or spin states. Results from metallic and molecular junctions will be presented. -

Weissman Building of Physical SciencesLecturer Yitzchak Pilpel, WIS Organizer Department of Physics of Complex SystemsContact Abstract Show full text abstract about Evolution is “survival of the fittest”, but how is “fittest”...» Evolution is “survival of the fittest”, but how is “fittest” defined? In simplest definitions, the fittest is the one who reproduces the fastest or with highest number of offspring. However, theories suggest that at certain situations others could be selected for. I will discuss two interesting cases. In communities that generate public goods, cooperators and defectors form more complicated evolutionary dynamics in which “fittest” depends on frequency of each strategy. Separately, the ability of evolution to select for the fastest reproducing variant is also balanced against the rate of mutations, and the quasi species theory predicts that at sufficiently high mutation rate the fastest might not necessarily be selected for. My lab employs synthetic DNA libraries and lab evolution to examine complex communities that reveal who really survives in evolution as a function of community structure and mutation rates. This very informal talk will present thoughts and challenges and preliminary results along these lines. -

A few nanometer thin interface which is formed between the metal and the organic structure controls bonding strength, stability and charge transfer between these two quite different types of materials. To understand and optimize formation of that interface at the nanoscale we used Self-Assembled Monolayers (SAMs) which are considered a model system for the analysis of the interaction of organic molecules with the metal substrate. In this presentation we will focus on application of a new experimental approach based on ion beam-induced desorption which we used to address this problem demonstrating for the first time the effect of oscillations in stability of consecutive chemical bonds at the molecule-metal interface. As a next step we will analyze the consequence of this effect for the thermal stability of a model SAM systems and, finally, we will discuss how this effect can contribute to the charge transport at the molecule-metal interface

NMR Across the Periodic Table: Observing "Invisible" Nuclides in Solid Materials

Recent developments in pulse sequences and NMR hardware have opened up many "exotic" nuclides in the periodic table to experimentation by solid-state NMR. Many of these nuclides are classified as unreceptive, and have been avoided by NMR spectroscopists and chemists in general, due to factors such as low Larmor frequencies, low natural abundances, inconveniently short or long relaxation times, etc. In addition, there are numerous systems in which these nuclides have extremely broad NMR patterns resulting from large anisotropic chemical shielding or quadrupolar interactions. Such nuclei have long been classified as "invisible", since their NMR spectra cannot be observed using standard NMR pulse sequences. In this lecture, I will show that there are several robust strategies one can apply to acquire high quality solid-state NMR spectra of a variety of nuclei, including 10B, 14N, 27Al, 35/37Cl, 47/49Ti, 59Co, 63/65Cu, 69/71Ga, 91Zr, 93Nb, 139La, 195Pt, and 209Bi. Ultra-wideline NMR spectra, when coupled with X-ray crystallography and ab initio methods, provide powerful probes of molecular structure in inorganic, organic and organometallic materials. New advances in dynamic nuclear polarization (DNP) NMR for the acquisition of ultra-wideline NMR spectra will also be discussed
