| 11:00 - 13:00 Seminar Detailed Computer Simulations of the Electric Current in the Brain. The case of transcranial direct current stimulation (tDCS). School COGNITIVE SCIENCES Abstract: We simulated electric current distribution in the brain during transcranial direct current stimulation (tDCS) using an anatomically accurate human head model. We estimated an effect of common electrode montages on spatial distribution of the electric field during tDCS procedure and analyzed a sensitivity of the technique to variations of electrode size and orientation. We concluded that the used electrode montages are stable with respect to minor changes in electrodes size and position, while an assumption of homogeneity and isotropy of the head model results in crucial changes of electric field distribution. We determined t ... 13:30 - 15:00 Weekly Seminar Relative entropy and measuring consistency between different cosmological data setsrd Alimohammadi Prize in Mathematics School ASTRONOMY In this talk, first of all, I will review statistical inference methods and describe how one can compare a theoretical model with observational data. After this, I will argue about importance of Bayasian statistics and overview some numerical method for generating posterior samples. Considering Baysian theorem, it is possible to update prior probability density on the free parameters to achieve the posterior probability density. In such a process, the relative entropy from information theory, measures the information gain between prior and posterior. I will progress further and describe the Surprise which provides a general and robust measure ... 14:00 - 16:00 Seminar a review on theories of consciousness School COGNITIVE SCIENCES Abstract: Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran on map * To join the mailing list: Send an empty email to: scs at ipm dot ir on the subject of: #join ... 15:00 - 16:00 Weekly Seminar Impact of unidentified light charged hadron data on the determination of pion fragmentation functions School PARTICLES AND ACCELERATORS Abstract: Essential ingredients of theoretical predictions for the present or future hadron colliders such as the large hadron collider (LHC) or large hadron-electron collider (LHeC), are the detailed understanding of hadrons in terms of their partonic constituents, and their emergence from quarks and gluons. Fragmentation Functions (FFs) are some of the tools, which bring such an understanding from high-energy particle physics. In our recent paper [arXiv:1901.01120 [hep-ph]] a new comprehensive analysis of parton-to-pion FFs is performed for the first time by including all experimental data sets on single inclusive pion as well as unidentifi ... 15:30 - 17:00 Geometry and Topology Weekly Seminar Ricci Flow and some of its Application School MATHEMATICS ... |
