Originally, this workshop was led by the late Prof. Mahir Hussein who organized alternating workshops on Nuclear Physics and on Ultracold Atoms and Chaos. Pursuing his ideals, the upcoming São Paulo Workshop deals with Ultracold Atoms. Since the realization of experiments with ultracold atoms in the 90’s, a new field has emerged with themes like atomic Bose-Einstein condensation, BEC-BCS crossover with fermionic atoms, and quantum phase transitions, for instance, with atoms in optical lattices, quantum fluids, nonlinear waves in quantum fluids, etc. In recent years, attention has focused on these systems in constrained geometries, as exemplified most prominently by the recent bubble trap experiments in the Cold Atom Laboratory of the International Space Station. For these reasons, we have decided to focus this workshop on low-dimensional quantum gas physics.

In addition to the invited talks there will be space for contributing posters that will be displayed during the coffee breaks.

This activity will be preceded by the “School on Light and Cold Atoms“. Candidates may apply either for one or both activities.

There is no registration fee.

Progress made during the past four decades in techniques for producing and controlling cold matter gave rise to the experimental manipulation of quantum gases, exotic states of matter, and the implementation of quantum simulators for condensed matter Hamiltonians. In addition, progress in the production and manipulation of quantum states of light and the suppression of classical noise allowed for the emergence and control of special coherence properties and quantum statistics, for both matter and light. These developments brought the fields of quantum optics and ultracold matter closer to applications, for example, in quantum sensing and quantum information processing. This common field of research represents today a privileged platform for fundamental discoveries of non-classical properties of light and matter, and an incubator of new quantum technologies.

This school aims at training PhD students, post-docs and outstanding master students in the physics of optics and cold atoms, introducing them to the basics, and familiarizing them with applications in modern technologies.

This activity will be followed by the “Workshop on Low Dimensional Quantum Gases“. Candidates may apply either for one or both activities.

There is no registration fee and limited funds are available for travel and local expenses.

Previous Seminars

Quantifying and integrating molecules for a more precise medicine (click to watch)
Speaker: Helder Nakaya – Albert Einstein Instituto Israelita de Ensino e Pesquisa
Date: July 28, 2022 14:30
Abstract: Diseases are mostly a consequence of an abnormality in multiple genes. Network Medicine investigates how genes interact to each other in complex intracellular and intercellular networks. The talk will show the recent advances on this emerging field of research and its impact on precision medicine and drug repositioning in Chikungunya, Zika, Malaria and Yellow Fever.

Theory, Models and Methods in Macroecology (click to watch)
Speaker: José Alexandre Felizola Diniz Filho – Universidade Federal de Goiás
Date: August 4, 2022 14:30
Abstract: Macroecology, as a relatively new field in Ecology, holds distinct methodological characteristics that lead to profound philosophical changes in the nature of evidence to support and build theories and models. One reason for this is the impracticability of controlled or manipulative experimental studies at broad spatial and temporal scales, as well as historical contingencies and the complexity of ecological dynamics at these scales. We follow here a model-based reasoning for building scientific theories and show in particular how computer simulation models, applied to different case studies in diversity gradients, can be successfully used in macroecology as mediating theory and data.

Assessing risks to biodiversity from climate change using macroecological and macroevolutionary models
Speaker: Andreas L. S. Meyer – University of Cape Town
Date: August 11, 2022 14:30
Abstract: Climate change is already causing local biodiversity losses, affecting ecosystems, and disrupting the life-supporting services they provide to people. However, our ability to forecast biodiversity responses and identify species most at risk from climate change remains insufficient. Here, I will explore how macroecological and macroevolutionary models can help us predict ecological and evolutionary responses of biodiversity to climate change. I will also show how simple, intuitive models can provide unprecedented information to assess risks and improve conservation prioritization and decision-making processes.

Unveiling complexity in ecology and evolution (click to watch)
Speaker: Flávia Maria Darcie Marquitti – Universidade Estadual de Campinas / ICTP-SAIFR
Date: August 18, 2022 14:30
Abstract: Mathematical and computational models are powerful tools to investigate patterns and delve into the processes behind them, making sense of the complexity of natural systems, from individuals to communities. In this talk, I will present the two main lines that guide my research: interaction networks and evolutionary models. In the first part, I will discuss how interactions across different levels of organization are shaped in nature and discuss the theoretical processes that may have resulted in observed interaction patterns. In the second part, I will address how genetic structure is important for the evolution of strategies and how the evolutionary process leaves signals in phylogenetic trees.

Population genomics in space and time: insights from ancient DNA (click to watch)
Speaker: Prof Fernando Racimo – University of Copenhagen
Date: September 14, 2022 11:30
Abstract: The sequencing of ancient genomes has provided an unprecedented opportunity to study human evolutionary history over thousands of years, in different regions of the world. Here, I will describe several methods developed in our group to relate genomic data to informative parameters about population expansions, movement and adaptation, while explicitly accounting for both spatial and temporal dimensions. These include a new way to model the spread of ancestry in ancient genomes across a landscape, along with a new simulation framework for easily generating spatial simulations of arbitrary complexity. We have recently applied some of these methods to a new dataset including thousands of ancient human genomes and used them to infer major population movements over the past 13 millennia of Eurasian history.

Virus and satellite in ecological coexistence (click to watch)
Speaker: Adriana L Sanz Garcia – Georgia Institute of Technology
Date: September 21, 2022 14:30
Abstract: Cooperation is a main driver of biological complexity at all levels. In the viral world, gene sharing among viral genomes, complementation between genomes or interactions within quasispecies are frequently observed. In this contribution, we explore the effects of flexible associations between fully fledged viruses and subviral entities, such as virus satellites, in viral dynamics and, in particular, in stable viral coexistence. We devise a mathematical model to compare different situations of competition between two viruses and to quantify how the association with a satellite qualitatively modifies dynamical equilibria. The relevant parameter is the invasion fitness of each virus or of the virus-satellite tandem, which in the model depends on the transmission rate of viruses and on their effect on host survival. In a virus-virus competition, one of the viruses becomes eventually extinct, recasting the competitive exclusion law of ecology. However, an association with a satellite might change the outcome of the competition in two ways, either to favor the less competitive virus (regardless of whether it is the helper virus or not) or to allow for the stable coexistence of the two viruses and the satellite. The virus-satellite association differs from other mechanisms proposed in ecology to date to enhance species coexistence. We hypothesize that such an association constitutes a parsimonious evolutionary pathway towards more stable cooperative associations, such as bipartite viral forms, a collaborative association unique to viruses.

Unraveling the complexity of the plasma membrane from studies of symmetric and asymmetric model membranes (click to watch)
Speaker: Thais A. Enoki – Cornell University
Date: September 27, 2022 14:30
Abstract: Cell membranes play important roles in cell function. The plasma membrane (PM) has the fundamental structure of a lipid bilayer, and has thousands lipid species that evolved to have physico-chemical properties that promote, for instance, a non-random lateral organization. This physical barrier protects the cell, and is composed of two leaflets of different lipid composition, thus is termed “asymmetric”. These PM leaflets have very different phase behavior. The exoplasmic leaflet, which faces the extracellular environment, is well studied using symmetric bilayers. The coexistence of liquid phases, named liquid disordered (Ld) and liquid ordered (Lo), is related to cell biology concepts of membrane rafts in the cell PM and is important to understand protein sorting and trafficking, membrane signal transduction, and viral assembly. We report a domain size transition tuned by the lipid composition, which can be explained by competing interactions between the line tension and dipole-dipole repulsion. In this transition, phase domain size abruptly changes without changes in the phase properties. Moreover, we observe notable patterns of modulated phases as the domain line tension decreases along the domain size transition. We also found a simple and accessible method to measure domain sizes below optical resolution (~200 nm). In contrast, the cytoplasmic leaflet lacks the high melting lipids, which with cholesterol could form the Lo phase. Thus, we need to consider a more complex model of the plasma membrane, which includes leaflets of distinct lipid composition. We first describe a new method to prepare asymmetric vesicles. Here, we use the hemifusion of giant unilamellar vesicles (GUVs) and a supported lipid bilayer (SLB) to engineer asymmetric GUVs, (aGUVs). We use different fluorescent dyes to monitor the inner and the outer leaflets of these unsupported aGUVs, and confirm that all newly exchanged lipids in the aGUVs are found in their outer leaflets. To model the plasma membrane, we prepare aGUVs that have one leaflet that phase separates into Ld+Lo phases, whereas the apposed leaflet forms a single fluid phase in an ordinary symmetric vesicle. For asymmetric vesicles, dye partition reveals induced ordered domains. We observed different cases where an ordered domain can induce order in the apposed leaflet. In addition, our results suggest that the induced ordered domains of the PM model are enriched in cholesterol. Therefore, the cytoplasmic leaflet may have “raft-like” domains induced by the exoplasmic leaflet.

Notification delay, a common problem on disease notification and how to correct it (click to watch)
Speaker: Leonardo Bastos – Programa de Computação Científica- Fiocruz
Date: October 4, 2022 14:30
Abstract: Notification delay in infectious disease surveillance consists in the time between the disease occurrence (symptoms onset) and the recording day. The second date refers to when the health system is aware of that case. Notification delay is a well-known problem in disease surveillance and usually the last days or weeks in a time series of disease counts tends to be ignored, otherwise a misunderstanding of the disease dynamic shall happen. However, this “solution” is far from optimal in an early warning system (EWS) for outbreaks, because the EWS would be too late to identify an outbreak. In this talk I will present a statistical approach to correct the delay that jointly model the delay and the time components proving predictions with uncertainty of the occur-but-not-yet-reported cases. The baseline model and some extensions will be presented and applied to different infectious diseases like COVID-19, dengue, chikungunya and malaria in Brazil. An R package is under development and will also be presented.

Pathogen dynamics across scales: from strain diversity to climate forcing (click to watch)
Speaker: Pamela Martinez Vargas – University of Illinois at Urbana-Champaign
Date: October 5, 2022 14:30
Abstract: The ecological and evolutionary mechanisms that influence the population dynamics of infectious diseases remain an active area of research of relevance to fundamental biology and applied public health. Temporal and spatial changes in infectious disease dynamics are difficult to anticipate due to the effects of environmental and climate drivers on the transmission of pathogens, and the complex diversity that these microorganisms exhibit. To address these challenges, I use mathematical models to study (1) how pathogen diversity interacts and interferes with intervention strategies and (2) how environmental and demographic factors shape the population dynamics of infectious diseases in space and time.

Structure and dynamics of complex parasite-host networks and their consequences for disease outbreaks
Speaker: Cecilia Siliansky de Andreazzi – Department of Biodiversity, Ecology and Evolution of the Complutense University of Madrid and Instituto Oswaldo Cruz -FIOCRUZ
Date: October 6, 2022 14:30
Abstract: Ecological communities are structured in networks of interacting species that shape and are shaped by ecological and evolutionary processes. To raise the challenge of understanding the mechanisms driving parasite spillover and disease outbreaks, we still need to develop approaches that capture the eco-evolutionary feedbacks connecting landscape use and community-level dynamics to the population-level processes that shape species abundances and trait evolution. In this talk I will discuss the effects of parasite-host coevolution on network structure and dynamics, how deforestation-driven changes affect parasite-host networks and if the reconfiguration of interactions amplifies or dilutes the risk of parasite spillover.

The developmental basis of biological diversity: lessons from mammalian skin
Speaker: Ricardo Mallarino – Princeton University
Date: October 26, 2022 14:30
Abstract: The overall goal of my laboratory is to understand the molecular mechanisms by which phenotypic traits are established and elucidate how these processes are modified during evolutionary time to produce the spectacular phenotypic diversity seen in nature. To achieve this, we develop genomic and experimental approaches in non-traditional model species and focus on questions relating to patterning and the evolution of novelty in the mammalian skin. Mammalian skin is a powerful model because it exhibits remarkable diversity in structure and function across species, is experimentally accessible/tractable, and the molecular mechanisms underlying its formation are well characterized. In this talk, I’ll describe our recent work aimed at understanding two distinct spatially patterned phenomena during skin development (1) color pattern formation in rodents, and (2) formation of gliding membranes in marsupials. I’ll discuss how we are using a variety of approaches, including experimental embryology, transcriptomic and epigenomic profiling, comparative genomics, functional genetics, and imaging, to uncover gene function and understand mechanisms of evolutionary change. Together, by focusing on developmental mechanisms, our work seeks to provide a comprehensive roadmap for linking genotype and phenotype at an unprecedented mechanistic and conceptual level.

Patterns, processes, correlations, and causality: what is behind species and phenotypic diversification in vertebrates? (click to watch)
Speaker: Gustavo Burin – Department of Sciences (Division of Vertebrates) Natural History Museum – London/UK
Date: November 03, 2022 14:30
Abstract: Biodiversity has constantly changed in myriad ways throughout the history of life on Earth. Diversification, the balance between speciation and extinction, is influenced by many variables, including environmental and biological factors, and so are species’ phenotypes. During the several millions of years of a given lineage’s lifespan, we expect that the factors driving diversification dynamics will also change in relative importance. Identifying and quantifying how these factors drive diversity trajectories are therefore crucial to our understanding of past and current biodiversity. A plethora of macroevolutionary methods and techniques have been proposed to address increasingly complex questions about the drivers of diversification dynamics. However, several conceptual and methodological gaps still prevent researchers from directly examining phenomena of interest. One important issue is that most approaches are based on correlation tests and lack an assessment of the causal relationships between each system’s components, meaning that observed patterns cannot be causally inferred. This is especially true for complex systems with many interacting components. My work aims to address these gaps by both using multiple sources of information and implementing new approaches specifically developed to test for causality in time series to macroevolutionary data. To accomplish this, I use both diversification and phenotypical evolution dynamics to address fundamental questions in Macroevolution, drawing hypotheses from the observed patterns that can be tested using ecological information such as niche space occupation, and past and current geographical distributions. I will show some of my studies using tetrapods, a group with plenty of molecular, fossil, and ecological information available that makes them very useful to help me tackle most of my questions.

Evolution of complex traits: from genotypes to phenotypes to ecosystem services. (click to watch)
Speaker: Ana Paula Aprigio Assis – Departamento de Genética e Biologia Evolutiva, Universidade de São Paulo
Date: November 09, 2022 14:30
Abstract: My research explores how ecological and evolutionary processes interact to determine populations’ responses to environmental change. Adaptive responses are determined by the magnitude and direction of selection, but also by patterns of variation and genetic covariation among traits. Throughout my career, I have studied how these two components (selection and genetic variation) interact to determine the direction and rate of evolution. To study this, I use a combination of empirical and theoretical approaches based on quantitative genetics and ecological theory.

The shape of vocal communication in a non-human primate
Speaker: Daniel Y. Takahashi – Instituto do Cérebro, Universidade Federal do Rio Grande no Norte
Date: November 16, 2022 14:30
Abstract: Primate societies coordinate group actions by communicating with each other. Often such coordination is achieved by exchanging vocalization with each other. When the vocalization itself is modulated by other vocalizations, i.e., a feedback loop is established, a complex dependence of calls emerges where what one animal vocalizes depends on the history of its own vocalization. (1) How can we understand the dynamics and neural basis of vocal interactions that are subject to dynamic interactions? Vocal communication changes during development together with changes in the entire body and social environment. The change in vocalization affects the body and social environment and vice-versa in such a way that we cannot understand vocal development by decoupling one factor from the other. Hence, it is natural to ask (2) What do we mean by understanding vocal development when the body, brain, and environment are all dependent on each other? A general characteristic during the development of vocalization in vocal-learning primates is the existence of sudden non-linear changes in the call acoustics from an immature vocalization stage to a mature vocalization stage. (3) How can we explain the nonlinearity in the vocal development of these animals? In this talk, using marmoset monkey vocal behavior and mathematical modeling I will show that we can approach the three questions posed above.

From systems biology to evolutionary predictions
Speaker: Fernanda Pinheiro – Fondazione Human Technopole
Date: November 17, 2022 14:30
Abstract: Urgent challenges of modern medicine require understanding evolutionary processes. But how can we distill the seemingly overwhelming complexity of biological evolution into simple, quantitative frameworks that can ultimately generate evolutionary predictions? In this talk, I will explore the interface of systems biology and evolution to address this question in the context of antibiotic resistance. Bacteria evolve resistance to antibiotics through multiple mechanisms, which allow them to grow under conditions they should not. At its core, antibiotic resistance is an exercise in bacterial growth. Yet, the question of how resistance evolution affects cell growth at different drug levels is still open. I will present a fitness model that predicts growth rates of common resistance mutants from their effects on cell metabolism. The model integrates drug action and evolutionary response into bacterial growth laws. It predicts evolutionary trajectories of dosage-dependent growth rates and resistance levels, as well as the prevalent resistance mechanism depending on drug and nutrient levels. These predictions are confirmed by empirical growth inhibition curves and genomic data of E. coli populations. In a broader context, I will discuss how metabolic models linking systems biology, ecology and evolution can become a tool for predictions.

Microbiota interactions with the plant immune system

Paulo Teixeira

Escola Superior de Agricultura “Luiz de Queiroz”, Universidade de São Paulo

November 23, 2022 14:30

Abstract: Plants have a sophisticated immune system to fend off invaders and prevent diseases. Yet, they are normally inhabited by thousands of microbial species, many of which have beneficial effects on the host. How plants mount effective defenses against pathogens while allowing the colonization of commensals remains poorly understood. In this talk, I will discuss how the plant immune system interacts with the microbiome, highlighting recent findings regarding the suppression of plant immunity by commensal microbes.

SAIFR/Princípia Workshop on the Nature of Dark Matter

Written by Jandira on July 18th, 2022. Posted in

November 2-4, 2022 

ICTP-SAIFR, São Paulo, Brazil

Principia Institute

Home

The existence of dark matter has been established beyond any reasonable doubt by several observations at vastly different length scales. These include rotation curves of galaxies, weak and strong gravitational lensing, fluctuations in the cosmic microwave background, baryonic acoustic oscillations, and formation of structure in the universe. All we know about dark matter comes from its gravitational effects, and these observations tell us nothing about its microscopic nature and composition. Understanding the origin of dark matter is at the forefront of the observed phenomena that we cannot explain.

Although we do not know the particle nature of dark matter, we have collected enough data to definitively exclude a broad range of possibilities. First of all, we precisely know that dark matter currently constitutes 27% of the universe’s energy budget. Furthermore, it is mostly cold and massive, it is non-baryonic with suppressed (or vanishing) couplings to the strong and electroweak gauge groups, and it does not interact appreciably with itself. Collectively, these observational facts exclude the possibility that known particles could account for these data. Thus, unveiling its identity and non-gravitational properties is one of the most important questions in fundamental physics today.

This  workshop will cover interdisciplinary aspects of the experimental searches for dark matter and it will outline the viable models. We will devote special attention to those that involve non-standard production mechanisms as they allow dark  matter particles to be very light. Such light candidates require new detection strategies and have implications in cosmology and structure formation that we aim to address in the workshop. We expect that the workshop will establish an effective strategy for the exploration and identification of the dark matter particle representing an important step in the hunt for this unknown and elusive degree of freedom.

There is no registration fee.

Formação em Biologia e Ecologia Quantitativas realizada por ICTP-SAIFR e Instituto Serrapilheira começa em julho

Written by Malena Stariolo on June 30th, 2022. Posted in Blog do ICTP-SAIFR

Reportagem por Yama Chiodi e Malena Stariolo

Na próxima segunda, dia 4 de julho, começa a segunda edição do Programa de Formação em Biologia e Ecologia Quantitativas. Após uma primeira edição online, realizada em 2021, em 2022 o curso será presencial e contará com a participação de pesquisadores de ponta, que ministrarão minicursos para os 31 estudantes selecionados de diversas áreas e vindos de várias partes do Brasil e da América Latina. O programa surgiu a partir de uma parceria entre o Instituto Serrapilheira e o ICTP-SAIFR, visando cobrir uma demanda pela criação de uma comunidade de cientistas capazes de aplicar métodos matemáticos e computacionais à biologia e à ecologia no Brasil.

Ricardo Martínez-García, pesquisador do ICTP-SAIFR e coordenador científico das duas primeiras edições do programa, conta que o ICTP-SAIFR surgiu como um ótimo instituto parceiro, por sua tradição e objetivo de impulsionar a pesquisa em física teórica na América Latina e por realizar, desde 2012, a escola de verão de Biologia Matemática, organizada pelo pesquisador Roberto Kraenkel. “Pra mim foi como colocar juntos esses dois interesses, do ICTP-SAIFR de criar oportunidades para jovens cientistas latino-americanos, e do Serrapilheira de ter esse foco muito claro no treinamento de cientistas para estudar sistemas biológicos complexos”, afirma ele.

Durante os cinco meses de duração do programa, os participantes terão aulas com pesquisadores de ponta das áreas de biologia e ecologia quantitativas, além de terem a oportunidade de conviver uns com os outros, em um ambiente estimulante para trocas de ideias e experiências. Segundo a pesquisadora Flávia Marquitti (Unicamp), que participa da coordenação científica deste ano e liderará a terceira edição prevista para 2023, a presença de colegas e professores de origens, universidades e grupos de pesquisa diversos vai expor os alunos a diferentes formas do fazer científico e enriquecer eventuais trabalhos feitos após o treinamento oferecido pela formação.

A interdisciplinaridade é uma das grandes características do programa, nesse contexto Marquitti avalia que há poucos espaços interdisciplinares na pós-graduação no Brasil, o que acaba criando um vácuo na formação de cientistas capazes de solucionar problemas que só poderão ser resolvidos no trabalho conjunto entre biologia, matemática e outras áreas. Para ela, as disciplinas têm suas próprias abordagens e enxergam possibilidades distintas para problemas em comum. A pesquisadora comenta: “quando diferentes disciplinas trabalham juntas elas não são só uma soma. Falando especificamente da aplicação, de usar modelos matemáticos nas áreas biológicas, a gente ganha muita informação e consegue generalizar algumas coisas que só com o conhecimento das biológicas a gente não conseguiria”.

O caminho contrário também é verdadeiro. Se a matemática pode ajudar as ciências biológicas a construir formalismos e generalizações, os cientistas das exatas vão aprender que a biologia impõe importantes limites no que pode ser generalizável. A professora acrescenta que “não dá pra fazer uma teoria de tudo na biologia. Então, quando a gente une as duas áreas, as exatas aprendem a conhecer os limites biológicos, para só então conseguir modelos que sejam aplicáveis pras ciências da vida”.

Ambos os coordenadores científicos compartilham da opinião de que os espaços para formação e pesquisa interdisciplinar ainda são incipientes no Brasil e que, geralmente, aparecem muito tarde na carreira do pesquisador. Martínez-García diz que, no programa, os alunos vão ser treinados para problemas que não podem ser resolvidos por uma pessoa ou mesmo por um grupo de pessoas da mesma área de formação, segundo ele: “problemas como a perda de diversidade e as mudanças climáticas não vão ser resolvidos por pessoas de só uma expertise. Vão ser necessárias equipes transdisciplinares e eles vão ter que aprender a falar uns com os outros. Físicos e ecólogos normalmente não falam a mesma língua, por exemplo”. É por essa razão que Marquitti considera que o programa é de fato um treinamento, diferente de cursos acadêmicos tradicionais.

A expectativa é que, ao fim do programa, os alunos consigam trabalhar juntos em áreas interdisciplinares, além disso, outro objetivo é formar uma rede de pesquisadores que contribuirá para o avanço da ciência. Para isso, Martínez-García comenta que estão previstos encontros anuais entre os ex-alunos do programa, que poderão estreitar laços profissionais e de pesquisa. Entre 4 de julho até 2 de dezembro serão realizados minicursos, seminários de pesquisa, sessões de debate, journal clubs e outras atividades que os selecionados do programa poderão participar. Para conhecer em detalhe todas as atividades, palestrantes, temas e participantes, basta acessar o site do programa no endereço https://www.ictp-saifr.org/qbioprogram/.

Criado em 2017, o Instituto Serrapilheira é a primeira instituição privada de apoio à ciência e à divulgação científica no Brasil. Sem fins lucrativos e com recursos oriundos de um fundo patrimonial, já apoiou 150 projetos de pesquisa e 58 de divulgação científica.

O ICTP-SAIFR é um centro de pesquisa em Física Teórica, vinculado ao IFT-UNESP e ao Abdus Salam International Centre for Theoretical Physics em Trieste, com apoio financeiro da FAPESP, UNESP e Instituto Serrapilheira. O ICTP-SAIFR realiza diversas atividades de treinamento para pesquisadores, como workshops e escolas, o cronograma pode ser acessado no site do instituto: http://ictp-saifr.org. Além disso, o SAIFR também organiza atividades de divulgação e extensão para professores e estudantes de Ensino Médio e para o público geral, confira a programação em: http://outreach.ictp-saifr.org.
