Automatic Type Inference for Amortised Heap-Space Analysis. This book constitutes the refereed proceedings of the 22nd European Symposium on Programming, ESOP , held as part of the European Joint Conferences on Theory and Practice of Software, ETAPS , which took place in Rome, Italy, in March The effective field theories for these systems are not of the usual Landau-Ginzburg-Higgs type, rather, they are described by topological gauge theories. The goal of this GGI activity is to bring together theoreticians of different backgrounds, in condensed matter, high energy and mathematical physics, with the belief that interdisciplinary. Comments: 27 pages. This article originally emerged from a subsection of arXivv1 that had to be split into a separate paper on request of a referee. The final results in the present paper are, however, stronger and more general than those from the removed subsection of arXivv1. Each year, ICTP organizes more than 60 international conferences and workshops, along with numerous seminars and colloquiums. These activities keep the Centre at the forefront of global scientific research and enable ICTP staff scientists to offer Centre associates, fellows and conference participants a broad range of research opportunities.

Our stability analysis is done in the $(H,\rho)$ phase space at a finite domain concerning the hyperbolic critical points. According to our analysis, due to constraints imposed on the signs of $\mu_0$ from the phenomenological parameters involved in quartessence models $(\Omega_m^*, c_s^2, \rho_*)$, for an expanding and accelerating late. Quantum phase transitions occur at zero temperature when some non-thermal control-parameter like pressure or chemical composition is changed. They are driven by quantum rather than thermal fluctuations. In this review we first give a pedagogical introduction to quantum phase transitions and quantum critical behavior emphasizing similarities with and differences to classical thermal phase.

In this thesis, I study the behaviour of the Stepping-Stone model: a stochastic model from theoretical population genetics. It was introduced by Kimura and Weiss [1][2] as a simple model to investigate the interplay of the evolutionary processes of random genetic drift, mutation, migration and selection. In particular, they were interested in the behaviour of spatially-structured populations. Prof. A.

We perform a linear stability analysis of the radially symmetric configuration and we study the post-buckling behaviour through finite element simulations.

We find that the process of gyrification is triggered by the cortex growth and modulated by the competition between two length scales: the radius of the organoid and the capillary length.

Almost all other equations contain one or more arbitrary parameters (in fact, this book deals with whole families of partial differential equations), which can be fixed by the reader at will.
