2. Bridging the gap by building analogies
Organized by: Dr Sergio L. Cacciatori

View details
Analogue gravity was originally developed in order to test certain quantum effects on curved backgrounds, in particular Hawking radiation by reproducing the main characterizing conditions (horizons) in water. Successively, several different analogue systems where proposed for example, in Bose-Einstein condensates or optical systems and some interesting experimental results have appeared in recent years. However, analogue systems appear also beyond the realm of gravity so that one can try to simulate the Aharonov-Bohm effect in optical systems, or quantum wave functions using bouncing water droplets, study quantum spacetime models by using macroscopic quantum systems and so on.
In any case, the main idea is to note that completely different physical scenarios may have at least partially, common a mathematical modellization governing certain particular subsystems and/or configurations. The advantage may be that one of the two systems is inaccessible (for example, the black hole), whereas the analogue system may be reproduced in a lab (say the analogue water system). The ability to discover analogies, i.e. common mathematical models, may help in filling a double gap: the gap between the theory and the comprehension of a phenomenon and the gap between theory and experiment. In this spirit, the workshop will be devoted to general analogies.

View details
The AdS/CFT duality and its extensions create links between strongly coupled quantum field theories and weakly coupled gravity theories -and viceversa-, that have lead to new conceptual developments both in Physics and in Mathematics. It provides, at the same time, new methods for solving a variety of strongly coupled systems that appear in Physics, which are hard to study using more traditional approaches. Within the proposed workshop, we plan to discuss both the fundamental and the applied aspects of gauge/strings duality.
The fundamental issues include a further study of the string-theoretical origin of the duality, profiting from the enhanced understanding of the working mechanisms of the AdS/CFT conjecture. On the applied side, we will discuss strongly coupled systems of relevance to particle, nuclear and condensed matter physics. Applications to Cosmology will also be considered.
The workshop will start on Monday, September 2, 2013.

View details
Expectations from modern medicine are very high and this makes this field very demanding as far as the questions posed and the needed solutions are concerned, related to early diagnosis, effective therapy, accurate intervention, real time monitoring, procedures/systems/instruments optimization, error reduction and knowledge extraction. In parallel, following the explosive production of biological data concerning DNA, RNA and protein biomolecules, a plethora of questions has been raised regarding their structure, their function, the interactions between them, their relationships and their dependencies, their regulation and expression, their location and their thermodynamic characteristics. Furthermore, the interplay between medicine and biology leads to fields like molecular medicine and systems biology which are further interconnected with physics, mathematics, informatics and engineering creating new islands in the ocean of scientific interconnections like medical physics and biophysics, medical informatics, bioinformatics and computational biology, nanobiotechnology and astrobiology. We hope that this workshop will host exciting questions and intelligent algorithmic solutions in these interdisciplinary fields of medicine and biology bringing together scientists from different research fields into a creative and fertile scientific knowledge interchange.

Organized by: Prof Mahmoud I. Abbas
Co-organizers:
+ Show description
|
View details
In the field of activity measurement by means of gamma-ray spectrometry using semiconductor or scintillation detectors, one usually needs to know the detection efficiency for any specific source–detector configuration of concern. Because the experimental determination of the detection efficiency is tedious and even difficult for extended circular disc and volumetric sources, there are, in principle, three approaches to this issue:
• Analytical direct calculation.
• Monte Carlo simulation.
• Semiempirical method.
In addition, we can use commercial software or code to calculate the Semiconductor and Scintillation Detectors Efficiency.

18. Topics in 2+1 dimensional gravity
Organized by: Prof Mohammad R. Setare
Co-organizers:

|
View details
It is well known that Einstein gravity suffers from the problem that
the theory is nonrenormalizable in four and higher dimensions.
Adding higher derivative terms such as Ricci and scalar curvature
squared terms makes the theory renormalizable at the cost of the
loss of unitarity. A few years ego a new theory of massive gravity (NMG) in three dimensions has been proposed. This theory is
equivalent to the three-dimensional
Fierz-Pauli action for a massive spin-2 field at the linearized level. Moreover NMG in contrast with the Topologically
Massive Gravity (TMG) is parity invariant. With the only Einstein-
Hilbert term in the action there are no propagating degrees of freedom, but by adding the higher curvature terms in the action the situation becomes different. Usually the theories including the
terms given by the square of the curvatures have the massive spin 2 mode and the massive scalar mode in addition to the massless graviton. Also the theory has ghosts due to negative energy excitations of the massive tensor.\\
The aim of this workshop is to discuss on various issues in this field.

View details
Information inequalities are the one of the moin tools of information theory. Clasical information inequalities (Shannon inequalities) are not enough top deal with the many applications of entropy. New information inequalities began to appear in the last few yers. Those new inequlities are called Non-.Sahonnon inequalities. We know that they define a family of higher dimensional convex cones, called entropic regions, and whose structure is far from being understood. In the workshop we would like to discuss the recent advances in the study of the entropic regions as well as the applications of information inequalities in different areas (such as Economy, Physics, Communications, Cryptography...)
20. ECG signal processing and telecardiology
Organized by: Dr Chouakri Sid Ahmed
Co-organizers:
+ Show description
|
View details
The electrocardiogram (ECG) signal is the electrical interpretation of the heart activity; it consists of a set of, well defined, successive waves namely P and T waves and QRS complex. The ECG provides to the cardiologist useful information about the heart functioning state; it indicates whether the heart activity is normal or shows anomalies such as the cardiac arrhythmia, myocardial infarct, angina, and ischemia. A great intention has been paid to the adequate and accurate analysis of the ECG signal that would lead to cardiac anomalies diagnosis. Signal processing technics, based of advanced numerical methods, have the goal of correctly analyzing and treating ECG signal aimed to aid-diagnosis for cardiologists and technicians. Besides this off-line treatment of ECG signal, the need for remote cardiac pathological patients care, exploiting the huge advances in telecommunications systems, arise the telecardiology technology. The main challenge of the telecardiology is preserving the higher hearth information fidelity of the transmitted ECG signal. Various signal processing techniques have been introduced in this context namely: compression, coding, modulation, shaping filters… In sum, signal processing as well as numerical methods play a considerable role in electrocardiology.
Topics of interest of the symposium include, but not limited to:
• ECG waves delineation algorithms;
• Time-frequency analysis of ECG signal;
• ECG filtering and denoising;
• Cardiac anomalies diagnostics technics;
• ECG compression;
• Telecardiology: shaping filers, modulation, coding…
21. Mathematical modeling of molecular quantum systems

View details
The general scope is mathematical modeling of molecular systems subject to external fields and perturbations of various kinds. By this we include electronic correlations, inelastic scattering effects, time-dependent phenomena, co-operative effects, spin-dependent conditions and effects, et c for systems under equilibrium and non-equilibrium conditions.
The mathematical challenges for those types of theoretical investigations have proven to be huge. Time-dependent and non-equilibrium phenomena are often very challenging by themselves, however, the dynamical aspects of physical phenomena are often more descriptive and provide deeper insight to the inner properties of the system.
22. Geometric integration in physical sciences and engineering
Organized by: Dr Odysseas T. Kosmas
Co-organizers:
+ Show description

View details
Many differential equations, which are of interest in the physical sciences and engineering, exhibit geometric properties that are preserved by the dynamics. Discrete Lagrangian integrators, as a special type of geometric integration, has been recent interest in developing numerical schemes that preserve as many of these geometric invariants as possible. Such methods are of particular interest for problems that can be described by geometric mechanics, wherein the preservation of physical invariants such as the energy, momentum, and symplectic form can be important when simulating long-time dynamics of such systems.
The aim of the session is to bring together researchers in mathematics, computer science, physical sciences, and engineering, who are interested in the broad area of numerical methods (for ordinary differential equations to partial differential equations) that preserve the underlying structure of the governing differential equations.
Some of the main topics (but not only) are:
- construction of high order techniques
- time symmetry problems
- constrained dynamical systems
- Multi-symplectic and high order integrators
- Lie Group Integration Schemes
- Hamilton-Pontryagin integrators
- Asynchronous Variational Integrators
- Discrete Mechanics, Multibody Systems
- stiff problems
- and applications in real problems
23. Modeling DNA: a challenge for nonlinear science

DNA denaturation has been since long a focus for the statistical physicists and biophysicists communities.
Besides being a template for fundamental biological functions such as replication and transcription, the thermally (or mechanically) driven separation of the complementary strands are currently under investigation also for their potential in designing nanodevices and molecules with technological applications. While fully atomistic descriptions of the double helix are computationally intractable due to the myriad of degrees of freedom even in short sequences, theoretical investigations usually start from mesoscopic Hamiltonians incorporating nonlinear effects and interactions at the level of the nucleotide units.
This workshop discusses the state of the art models for DNA molecules with emphasis on its dynamical and equilibrium properties.

View details
Half-metallic materials are characterized by two types of band structures, while one of them (usually the majority-spin band) shows a metallic behavior, the minority band exhibits a semiconducting behavior, which leads to a 100% polarization at the Fermi level. Therefore, they are promising for spintronic applications, which depend on the movement of spin as well as the charge to carry information among devices. This workshop will cover topic of electronic structure calculations of transition-metal oxides, dilute magnetic III-V compounds and Heusler alloys.

The knowledge of the Universe as a whole, its origin, size and shape, its evolution and future, has always intrigued the human mind. Galileo wrote: "Nature's great book is written in mathematical language." In this Workshp we aim at collecting some contributions to enforce this statement. All issues which touch upon these ideas will be considered, questions such as: Is our universe finite or infinite? Is the cosmological constant at all there? What drives the acceleration of the Universe expansion? Dark energy, but what is it? What are the different uses of zeta functions and other special functions of mathematical analysis in present day physics? Beautiful mathematics are key in dealing with those questions and in providing the bridge which is crucial to understand (or just describe, modellize) the Universe we live in.
31. Dark Matter Phenomenology in Astronomical and Astrophysical Scenarios
Organized by: Dr Lorenzo Iorio
Co-organizers:

View details
Recently, important developments have occurred in the Dark Matter (DM) field.
A significative revision of the currently accepted content of non-baryonic DM of the Universe has been offered by the latest Planck data; now, it would amount to about 26% with respect to 23% from WMAP.
The Large Area Telescope (LAT) on the Fermi Gamma Ray Space Telescope spacecraft recently discovered a gamma-ray
excess at the Galactic center which may be due to DM annihilation
phenomena.
There is a lingering debate concerning the amount of DM in our Solar System. Low upper bounds, of the order of 0.04 GeV cm^-3, for its energy density have been recently inferred. Nonetheless, they have been criticized pointing towards a higher level of 0.3 GeV cm^-3, in agreement with previous estimates.
Hints of DM might have been detected by the Alpha Magnetic Spectrometer (AMS) on the International Space Station, which has recently measured an anomalous high-energy positron excess in Earth-bound cosmic rays.
An accurate knowledge of the DM distribution in the neighbourhood of the Solar System is relevant for the attempts aimed to directly detect DM par-ticles in laboratory-based experiments such as, e.g., CDMSI, CDMSII, DAMA/NaI and its successor DAMA/LIBRA, XENON10 and ZEPLIN III.
Thus, it has become even more important to devise independent means to effectively gain information on the constitution and the distribution of such a hypothesized, elusive ingredient of the natural world.

View details
The general theory of relativity is one of the fundamental pillars of our knowledge of the natural world, being, to date, the best theory of the grav-itational interaction at our disposal. Thus, it is important to put it on the test in as much ways as possible to increase our confidence in it, especially in
view of the extrapolations of its validity to extreme scenarios. In these cases, empirical checks are difficult and/or the interpretation of existing observations heavily rely upon more or less speculative assumptions concerning the history of the systems considered and the physics governing them in such
regimes.
