Inaugural session Welcome to PWF and EPIC 3

Talk: The Frontiers of Computational Physics

• Helga Denes (Yachay Tech)

Today computers and computation is part of everyday life and one of the essential components of science. To name some examples, our mobile phones are more sophisticated computers than the first PCs, our IDs tend to be digital, everyone has emails and most people have mobile banks. In the last few months the new artificial intelligence (AI) softwares have generated much attention, however AI has been behind many computer applications for several years. Computation in the sciences has had a long history since the planning of the first Moon Landing in the 1960 to todays most advanced supercomputers. One of the obvious fields of scientific computing is the more and more complex theoretical computer simulations that drive the development of supercomputers. Another important fields are the computers that power the instruments of experimental research. For example, the brains of modern radio telescopes and large particle accelerators are supercomputers as well. In addition, to taking and generating data it is also essential to have the tools to analyse, visualise and disseminate this data. Having a good knowledge of computing these days can open the doors for working in sciences, in industry and in public offices.

Talk: Analysis of the generalized Starobinsky inflationary model

• Clara Rojas (Yachay Tech)

In this work we solved the equation of scalar and tensor perturbations for the generalized Starobinsky inflationary model using the improved uniform approximation method and the phase-integral method up to third-order in deviation. We compare our results with the numerical integration. We have obtained that both semiclassical methods reproduce the scalar power spectra P, the scalar spectral index nS, and the tensor-to-scalar ratio r. Also we present our results in the (nS,r) plane.

Tutorial: FFT methods for fluid dynamics

• Wladimir Banda Barragán (Yachay Tech)

In this tutorial you will learn to use Fast Fourier Transform algorithms in python to solve parabolic and hyperbolic partial differential equations. There will be guided examples on how to solve the fluid dynamics equations and you will have the chance to work on proposed problems too.

Tutorial: Monte Carlo methods for physics

• Wladimir Banda Barragán (Yachay Tech)

In this tutorial you will learn to carry our Monte Carlo simulations in python with the purpose of studying physical systems. There will be guided examples on how to carry out Monte Carlo simulations, and you will have time to work on a proposed problem too.

Talk: Using deep learning to understand fish development

• Andres Morales Navarrete (U Konstanz)

The Pseudospectra is a powerful tool to analyze the behavior of dynamic systems associated to non-normal matrices. Studies and applications have increased in the last decades, thus, its efficient computation has become of interest for the scientific community. In the large scale setting, different approaches have been proposed, some of them based on projection on Krylov subspaces. In this talk, we will present a scheme for the parallel computation of the Pseudospectra, based on a domain decomposition of the interest region into subregions that can be assigned to a set of processors in order to accelerate the computation.

Talk: Pseudospectra of matrices and its computation

• Zenaida Castillo (Yachay Tech)

Talk: The framework ROOT CERN and its use in particle physics

• Gustavo Loachamin (PUC Rio de Janeiro)

Data analysis is a key component of experimental physics, this is why the knowledge of frameworks and programming languages is necessary for physicists. In particle physics for example, the ROOT framework is widely used because of its graphical interface for interactive analysis and its capacity to store and analyze large sets of data of more than 1 exabyte. In this talk, I will be introducing briefly the functionality of ROOT and relating it to my own research: the amplitude analysis of three-body decays.

Tutorial: Introduction to BioImage Analisys with Python

• Andres Morales Navarrete (U Konstanz)

Explanation about bioimages (i.e. fluorescence microscopy), Bioimage analysis example: quantifying cell morphology from 2D fluorescence micrographs, Importing images and plotting images, Logical operators (pixel-wise operations), Intensity Transformation, Filters and Fourier transformations, Segmentation, Extracting data from segmented images (e.g. cell area, elongation).

Tutorial: Deep learning for analisys and modelling of biological systems

• Andres Morales Navarrete (U Konstanz)

Tutorial: Excited-state dynamics

• Edison Salazar (U Groningen)

Photoinduced processes play a crucial role in different fields of science, for example, the photoisomerization of the retinal chromophore or the synthesis of vitamin D3. Additionally, they are crucial in the development of new technologies such as molecular electronic devices which can be controlled by light. These processes are governed mainly by nonadiabatic transitions which are radiationless electronic transitions between different non-Born-Oppenheimer states along the dynamic of a chemical reaction. In these two lessons, we are going to implement the Tully algorithm in Python to study a simple avoid crossing model as the first approach to a non-adiabatic transition.

Talk: La vocación de las mujeres para estudiar carreras STEM: una mirada de Ecuador

• Paulina Vizcaino (UIDE)

The social and historical construction of the role of women in society has been the subject of study of several feminist theories, which attempt to highlight the dichotomy in philosophical and sociocultural thought that validates the distribution of activities based on sex. The public, rational and technical has been relegated to men, while women represent the sensitive, emotional and private. This structure of stereotypes that is reproduced generationally allows us to discern the reasons why there are fewer women pursuing STEM careers. Identifying the reasons that drive women in their choice of a university career allows us to establish strategies to promote the vocation of women who are oriented towards science, technology, engineering and mathematics in Ecuador. The research also seeks to quantitatively evaluate the academic performance of women in STEM careers; and to analyze the participation of women in the field of research in higher education.The objective of the project is to analyze the factors motivating women to pursue STEM careers in Ecuador, Kazakhstan and India.
