Calabi-Yau manifolds, mirror symmetry, and $F$-theory - part I

David R. Morrison
There are five superstring theories, all formulated in 9+1 spacetime dimensions; lower-dimensional theories are studied by taking some of the spatial dimensions to be compact (and small). One of the remarkable features of this setup is that the same lower-dimensional theory can often be realized by pairing different superstring theories with different geometries. The focus of these lectures will be on the mathematical implications of some of these physical “dualities.” Our main focus from the...

Surgical Techniques for Functional Mitral Regurgitation

Joseph Lamelas
Joseph Lamelas of the Texas Heart Institute in Houston discusses different surgical techniques to address ventricular dysfunction in functional mitral regurgitation. He presents video of his prefered technique, termed "Ring & Sling," in which a graft draws the papillary muscles together.This presentation was originally given during the SCTS Ionescu University program at the 2017 Annual Meeting of the Society for Cardiothoracic Surgery in Great Britain and Ireland.

Factors to consider

Rosa Sola-Molina
This item has a power point including factors that have been considered in previous research when researching neural underpinnings of reach to grasp movements. It lists areas of research from fMRI/MEG studies, and patterns in activity that may represent top-down/bottom-up loops during visuomotor transformation from MEG studies.

Plethysmography 6b - Analysis [video]

Ollie Jay
The Plethysmography videos are for measuring limb blood flow with strain gauge plethysmography, using the DualSGP program. Analysis requires use of Notepad and Excel.

A microlocal toolbox for hyperbolic dynamics

Semyon Dyatlov
I will discuss recent applications of microlocal analysis to the study of hyperbolic flows, including geodesic flows on negatively curved manifolds. The key idea is to view the equation $(X + \lambda)u = f$ , where $X$ is the generator of the flow, as a scattering problem. The role of spatial infinity is taken by the infinity in the frequency space. We will concentrate on the case of noncompact manifolds, featuring a delicate interplay between...

Linking a rural sanctuary with ancient metallurgy at Kataliondas Kourvellos (Cyprus)

Patrizia Birchler Emery, Athos Agapiou, Dragos Constantin, Julien Beck, Vasiliki Lysandrou, Kyriakos Themistocleous & Bertrand Merminod
Kataliondas Kourvellos is located at the base of an unusual rock knob, in the lower Troodos foothills, about 20 kilometers south of Nicosia. Recent excavations by the University of Geneva revealed that the site was occupied both in the Pre-Pottery Neolithic period, at the end of the 8th millennium BCE, and in the Cypro-Classical period, in the 4th century BCE.During the Cypro-Classical period, the site seems to have functioned as a rural sanctuary, but the...

High frequency back reaction for the Einstein equations

Cécile Huneau
It has been observed by physicists (Isaacson, Burnett, Green-Wald) that metric perturbations of a background solution, which are small amplitude but with high frequency, yield at the limit to a non trivial contribution which corresponds to the presence of an energy impulsion tensor in the equation for the background metric. This non trivial contribution is of due to the nonlinearities in Einstein equations, which involve products of derivatives of the metric. It has been conjectured...

Teilchen im Einklang

Denis Postle & Peter Goodchild
Endeavours to explain the revelations of the search for the fundamental building blocks of the universe. Through experiments and analogies, the basic approach i n the research is described and indications given of how the results can be interpreted philosophically as well as physically.
Comments : This film generated a great deal of subsequent argument, in the press and journals and at the Institute of Physics Exhibition, about how well the film managed to convey to...

Easy-Going: The Treatment of Written Records in the Ancient Syropalestine

Pavel Čech
Who invented the Proto-Sinaitic writing? Sophisticated scribes, or unlettered workers? Orly Goldwasser, the chief advocate of the second possibility, borrowed from economic sciences the term ‘disruptive innovation’ that “describes a process by which a product or service takes root initially in simple applications at the bottom of a market and then relentlessly moves ‘up market,’ eventually displacing established competitors.”[1] During the years spent with translations of Levantine texts for a Czech kind of „Context of...
