During my MSc years we developed a strategy to increase pattern recognition in attractor neural networks. The idea was to reduce the similarity of memories, replacing each one with the pattern resulting from successive iterations of a (pseudo)chaotic cellular automaton rule. We also proposed a new dynamics that improved the Hopfield-Tank approach for solving the traveling salesman problem. Advantages of a neural-network implementation of the latter problem are their direct in-silico and optical implementations. My PhD thesis is divided in two parts. One deals with small-world networks, their geometric properties and the critical behavior of the average shortest-path length near zero addition of long-range bonds. We prove that the transition from regular to random behavior is first order. On the second part of the thesis nonequilibrium phase transitions are studied. We define a lattice model of structural rigidity and a translation of the latter problem into a reaction-diffusion one, finding numerical estimates of the set of critical exponents of the model. ===== Research ===== I have been introduced to the fascinating field of statistical mechanics of complex systems at the beginning of my undergrad years. I have learned many interesting problems like the traveling salesman problem, memory storage and retrieval in attractor neural networks, complex networks and other biologically-inspired problems. Some of these studies resulted in [[http://scholar.google.com/citations?user=hdWhavkAAAAJ|publications]]. Currently, I take part in a team effort developing [[http://pseudomonas.procc.fiocruz.br|a computational model for Pseudomonas aeruginosa]], a multi-drug resistant pathogen associated with a broad spectrum of infections in humans. My focus is on the reconstruction of its metabolic network. ===== Teaching ===== == Física Computacional - GFIXXXX == * Bibliografia e listas de exercícios - [[http://cursos.if.uff.br/fiscomp-0210/|2010-2]] * Bibliografia e listas de exercícios - [[http://cursos.if.uff.br/fiscomp-0111/|2011-1]] * Bibliografia e listas de exercícios - [[http://cursos.if.uff.br/fiscomp-0210/|2011-2]] == Semana da Física 2009 == * Mini-tutorial [[marcio:semana2009|"Ferramentas de Computação em Física"]] == Termodinâmica == * [[marcio:home:thermo|Maxwell construction and the Van der Waals equation]]\\ == Escola do CBPF 2010 == * {{:marcio:cbpf2010-aula1.pdf|Aula 1}} (Referencias e adicionais {{:referencias_aula1.tgz|aqui}}\\ * {{:marcio:cbpf2010-aula2.pdf|Aula 2}} (Referencias e adicionais {{:marcio:referencias_aula2.tgz|aqui}}\\ * {{:marcio:cbpf2010-aula3.pdf|Aula 3}}\\ * {{:marcio:cbpf2010-aula4.pdf|Aula 4}}\\ ===== Musica ===== __**Horace Silver Quintet & Elvin Jones Trio 1968 (On Jazz Omkring Midnat - Denmark TV)**__[[https://www.youtube.com/watch?v=0dX28TGFLwY|(link)]] {{youtube>0dX28TGFLwY?medium}} **Magic moment begins at 8:15 with Horace Silver, followed with perfection by Billy Cobham at 11:10** \\
