I will emphasize interesting relationships between these observables, and their common origin in a A-twisted topological field theory in two dimensions -

As the number of steps in a sequence of choices increases, the potential number of paths through a decision tree increases exponentially. How are we able to make good decisions in the face of such overwhelming complexity? One idea is that the brain uses shortcuts, or heuristics, to reduce computational demands. I will present evidence for the existence of a novel heuristic, "pruning", which entails avoiding even considering entire branches of a decision tree that begin with a large negative outcome, regardless of subsequent outcomes. We found that decision making was profoundly impaired when the optimal choice entailed initially accepting a large negative outcome (Huys et al 2012 PLoS Computational Biology 8(3):e1002410); and computational modelling showed that this bias could not be explained by other influences such as poor planning or loss aversion. A subsequent neuroimaging study, using a computational approach to assess pruning on a trial-by-trial basis, confirmed this behavioural effect, and suggested that pruning behaviour is driven by activity in brain regions implicated in emotional processing; in particular the subgenual cingulate cortex which plays a critical role in depression. These results will be discussed with reference to a contemporary theoretical framework that relates Pavlovian behavioural inhibition to serotonin and depressive symptoms. -

Info; addgene is a nonprofit organization founded to help scientists share materials and useful data across borders around the world. Addgene has distributed over 750,000 plasmids to scientists in 85 countries. This movement of samples has influenced fields from Stem Cells to CRISPR and almost everything in between. Addgene's Executive Director, Joanne Kamens will present on this unique compnay model, what's new with Addgene and about what it is like to be an Addgenie.
Dr. Kamens is the Executive Director of Addgene, a mission driven, nonprofit dedicated to helping scientists around the world share useful research reagents and data. Dr. Kamens received her PhD in Genetics from Harvard Medical School then spent 15 years as a researcher and manager in Pharma at BASF/Abbott working on both small molecule and antibody therapies for immune disease. In 2007 she joined RXi Pharmaceuticals as Senior Director of Research Collaborations. Dr. Kamens founded the current Boston chapter of the Association for Women in Science. She has helped start and supports many scientist mentoring programs with training and best practices. In 2010, Dr. Kamens received the Catalyst Award from the Science Club for Girls for longstanding dedication to empowering women in the fields of science, technology, engineering and mathematics and in 2013, she was named one of PharmaVoice's 100 Most Inspiring Commanders & Chiefs. She serves on a number of other non-profit boards and speaks widely on career development and workplace diversity topics in person and via Webinar.

Typically here turbulence arises despite the linear stability of the laminar flow and results from perturbations of finite amplitude. Turbulence at first appears in the form of localised patches (e.g. puffs, spots or stripes) which coexist with laminar flow, resulting in complex, disordered flow patterns (spatio-temporal intermittency). Individual turbulent domains can collapse or they can proliferate and seed other patches of turbulence. The time scales on which flows evolve are extremely large and likewise are the relevant length scales. Characterizing the transition process hence requires experiments of very large aspect ratios and extremely long observation times. In detailed experiments and direct numerical simulations of Couette flow we could for the first time determine the critical exponents that characterize this transition and show that it falls into the directed percolation universality class. In addition I will show how the obtained insights can be used to control and even fully suppress turbulence. -

Optics and Atomic Physics Seminarצרו קשר פרטים נוספים Show full text description of The control of quantum states is essential both for fundamen...» The control of quantum states is essential both for fundamental investigations and for technological applications of quantum physics. In quantum few-body systems, decoherence arising from interaction with the environment hinders the realization of desired processes. In quantum many-body systems, complexity of their dynamics further makes state preparation via external manipulation highly non-trivial. An effective strategy to counter these effects is offered by quantum optimal control theory, exploiting quantum coherence to dynamically reach a desired goal with high accuracy even under limitations on resources such as time, bandwidth, and precision. In this talk I will:
- introduce the quantum optimal control method we developed to this aim, the CRAB (Chopped Random Basis) algorithm, which is to date the only method that allows to perform optimal control of quantum many-body systems;
- present experimental results obtained via its application to various physical systems, from quantum logical operations in solid-state quantum optics to quantum criticality in ultra-cold atoms, both in open-loop and in closed-loop feedback scenarios, with applications ranging from quantum interferometry with Bose-Einstein condensates on atom chips to magnetic field sensing in diamond NV centers and to the preparation of optical-lattice quantum registers for quantum simulation;
- use these examples to illustrate the quantum speed limit, i.e. the maximum speed achievable for a given quantum transformation, and describe related effects of nonlinearity due to inter-particle interactions and more in general to dynamical complexity;
- propose a way to characterise the latter in an information-theoretical fashion by the bandwidth of the optimized control pulses, as well as a conjecture about using this method for discrimination between different levels of complexity in quantum many-body systems.תקציר Show full text abstract about The control of quantum states is essential both for fundamen...» The control of quantum states is essential both for fundamental investigations and for technological applications of quantum physics.
