Understanding Protein Mechanism With Computational Approaches
Proteins, which are essentially linear polymers of amino acid residues, perform
a tremendous variety of functions, including catalyzing biochemical reactions,
replicating genetic information, transporting molecules, constructing cell
architecture, and transducing signals in the microscopic milieu of cells and the
interstitial fluid. Such linear chains of residues undergo complicated folding
processes to form biologically active 3-dimensional structures as they are
translated. Since the first protein structure of myoglobin was determined using
X-ray crystallography in 1958, biophysicists have been making continuous efforts
to understand the associations between protein structures and their functions.
Unfortunately, only static snapshots and limited dynamics of proteins at
atomic-level resolution are available with the experimental approaches developed
so far, which precludes a complete biophysical and temporal understanding of
protein mechanisms in the context of the microscopic biochemical processes in
which they operate. Molecular dynamics (MD) simulations have been introduced as
a computational approach to acquire information about the full dynamics of
molecular systems, especially proteins. The method allows for sampling of the
time evolution of proteins in the form of trajectories (a collection of frames
containing precise coordinates), provides quantitative insights into how
proteins function, and has been widely used as an essential tool to understand
protein mechanisms.
Specialized computer hardware developed in recent years, coupled with improved
software implementations, have greatly accelerated MD simulations. A single
GPU-attached cluster is capable of producing microsecond-length trajectories in
reasonable amounts of time. As the timescales of MD simulations keep increasing,
it becomes more challenging to analyze long trajectories. Tasks such as
identifying the conformational states of proteins by clustering frames in
trajectories are usually resolved with unsupervised machine learning algorithms.
The quality of their results directly affects the answers of many biophysical
questions, which implies that using an appropriate analytical method for a
particular MD aim is as important as a sufficient sampling of protein
conformations. In the first two chapters of this dissertation, the basic theory
of MD simulations is introduced together with several important unsupervised
learning algorithms we used in investigating specific biophysical problems,
which target the issues of dimensionality reduction and clustering. These
algorithms include the novel data-driven and generative clustering algorithm we
developed based on adversarial autoencoders. Then we present our investigation
on the conformational dynamics and ion transport mechanism of the sodium iodide
symporter, which could be considered as an example of adopting MD and
unsupervised learning approaches to understand the working mechanisms of
proteins. In the last chapter, we introduce an application of computational
structural biology to large-scale drug screening
A COMPARISON BETWEEN MOTIVATIONS AND PERSONALITY TRAITS IN RELIGIOUS TOURISTS AND CRUISE SHIP TOURISTS
The purpose of this paper is to analyze the motivations and the personality traits that characterize tourists who
choose religious travels versus cruises. Participating in the research were 683 Italian tourists (345 males and 338
females, age range 18–63 years); 483 who went to a pilgrimage travel and 200 who chose a cruise ship in the
Mediterranean Sea. Both groups of tourists completed the Travel Motivation Scale and the Big Five
Questionnaire. Results show that different motivations and personality traits characterize the different types of
tourists and, further, that motivations for traveling are predicted by specific —some similar, other divergent—
personality trait

Proceedings of the 21st International Congress of Aesthetics, Possible Worlds of Contemporary Aesthetics Aesthetics Between History, Geography and Media
The Faculty of Architecture, University of Belgrade and the Society for Aesthetics of Architecture and Visual Arts of Serbia (DEAVUS) are proud to be able to organize the 21st ICA Congress on “Possible Worlds of Contemporary Aesthetics: Aesthetics Between History, Geography and Media”.
We are proud to announce that we received over 500 submissions from 56 countries, which makes this Congress the greatest gathering of aestheticians in this region in the last 40 years.
The ICA 2019 Belgrade aims to map out contemporary aesthetics practices in a vivid dialogue of aestheticians, philosophers, art theorists, architecture theorists, culture theorists, media theorists, artists, media entrepreneurs, architects, cultural activists and researchers in the fields of humanities and social sciences. More precisely, the goal is to map the possible worlds of contemporary aesthetics in Europe, Asia, North and South America, Africa and Australia. The idea is to show, interpret and map the unity and diverseness in aesthetic thought, expression, research, and philosophies on our shared planet. Our goal is to promote a dialogue concerning aesthetics in those parts of the world that have not been involved with the work of the International Association for Aesthetics to this day. Global dialogue, understanding and cooperation are what we aim to achieve.
That said, the 21st ICA is the first Congress to highlight the aesthetic issues of marginalised regions that have not been fully involved in the work of the IAA. This will be accomplished, among others, via thematic round tables discussing contemporary aesthetics in East Africa and South America. Today, aesthetics is recognized as an important philosophical, theoretical and even scientific discipline that aims at interpreting the complexity of phenomena in our contemporary world. People rather talk about possible worlds or possible aesthetic regimes rather than a unique and consistent philosophical, scientific or theoretical discipline

Today, aesthetics is recognized as an important philosophical, theoretical and even
