Europe/Rome 2019-09-23 14:00:00 2019-09-23 15:00:00 Memristive networks Nanoscale components often exhibit memory, both quantum and classical. Resistors are no exception (already at the classical level) and the use of memristors for a variety of purposes is currently under scrutiny. Applications range from machine learning on chip to compact and passive memory devices using crossbar arrays. In this talk we discuss the nitty-gritty mathematical aspects of memristive circuits in the analog regime (no CMOS), their connection to the Ising model, and plausible future directions beyond crossbars.   ICTP ICTP pio@ictp.it 23 Sep 2019

Europe/Rome 2019-09-24 11:00:00 2019-09-24 12:00:00 Understanding the underlying mechanisms of pattern formation and cellular aggregation Cellular self-assembly and organization are fundamental steps for the development of biological tissues. Within the framework of a cellular automata model, we address how an ordered tissue pattern spontaneously emerges from a randomly migrating single cell population without the influence of any external cues. The simulations also capture several dynamical properties of growing aggregates, such as, the rate of cell aggregation and non-monotonic growth of the aggregate area which show a good agreement with the existing experimental observations. We further investigate the ruggedness of the growing structures by evaluating the fractal dimension to get insights into the complexity of tumorous tissue growth which were hitherto unexplored. Efficient process of collective migration of cells can be dictated by incorporating different factors like mechanical, chemical and physical contact interaction present in the environment of cells for tissue development. Our work exploits the mathematical features of different kind of interacting forces and focuses on the contribution of these factors to the large scale organization.

Europe/Rome 2019-12-09 07:00:00 2019-12-20 21:00:00 ICTP-ICTS Winter School on Quantitative Systems Biology 2019 | (smr 3338) The International Centre for Theoretical Physics (ICTP) and the International Centre for Theoretical Sciences (ICTS) are organizing a joint winter school on quantitative systems biology. This is the 8th school in the series and will be held at ICTS, Bengaluru, India.   https://www.icts.res.in/program/qsb2019   QSB2019 is an advanced school aimed at graduate students and postdocs working in quantitative systems biology. The focus this year is on 'morphogenesis'. The main school will be held between December 9-20, 2019 and will be preceded by a pedagogic and intensive ‘Pre-School’ between December 3-6, 2019. The Pre-School will cover the basic concepts in cell and developmental biology and will have short modules on mathematical modelling and physical approaches to biology.     The deadline for applications is 1 September 2019.   The development of an organism from a single-celled zygote to an embryo involves a tight integration between gene expression, signaling and mechanochemical processes. In recent years, there has been an explosion in studies that attempt to unravel the physical principles behind how organisms self-organize to generate their three-dimensional shape and functional form. Novel microscopy techniques are giving unprecedented views into the processes of development at very high spatiotemporal resolution. This deluge of data necessitates a larger scale systems-level understanding how organisms build themselves. The eighth edition of the ICTP - ICTS winter school on quantitative systems biology is focussed on Morphogenesis and will allow students from different backgrounds to become familiar with exciting developments at the interface of Physics and Developmental Biology. The participants of the school will be exposed to contemporary research areas, covering a large variety of topics, including mechanochemical pattern formation, regeneration and growth regulation, evolutionary-developmental biology. The school will emphasize how major questions in developmental biology such as stem cell differentiation, morphogenesis, tissue patterning, and tissue mechanics, can be asked with the help of quantification and physical theory.
