Workshop RNTW01 — RNT in Radar, Astronomy and Geophysics
30 jan 2023 - 03 fév 2023 • Cambridge , Royaume-Uni
Organisateur:
Isaac Newton Institute for Mathematical Sciences (INI)
Résumé:
A large collection of inverse problems involve using waves scattered or emitted from an object to image its interior or to determine some of its material properties. Applications including radar and microwave imaging, astronomy, sonar, ultrasound, and geophysics, may share many characteristics. These applications also cover a spectrum of problems and length scales from low to high frequency, near to far field, static to highly dynamic, and from imaging discrete isolated objects to the interior of a continuously varying medium. Through this spectrum, different computational and theoretical challenges in inverse problems will arise – and understanding the transition through regimes can also provide new insights in and of itself.

This workshop will put a spotlight on the mathematical similarities of Rich and Non-linear Tomography across these applications in order to catalyse rapid development of new tomographic methods. As part of a highly interdisciplinary programme, the aim is for real-world problems in these applications to motivate a breadth of theoretical and practical mathematical research challenges – from microlocal analysis through to Bayesian methods. It will also help to break down communication barriers between disciplines and applications.

Workshop MWSW03 — Computational methods for multiple scattering
17 avr 2023 - 21 avr 2023 • Cambridge , Royaume-Uni
Organisateur:
Isaac Newton Institute for Mathematical Sciences (INI)
Résumé:
The accurate and efficient numerical modelling of waves interacting with complex scattering geometries is crucial for a wide range of engineering and science applications, including electromagnetic/photonic/acoustic/elastodynamic imaging and device/material design. The multiple scattering regime — i.e. wave scattering scenarios in which there are multiple interactions — includes strong scattering by multiple obstacles, periodic structures, media with variable refractive index, waveguides, random media, and non-convex obstacles. This brings special computational challenges since perturbative and one-way approximations do not apply, and ray methods usually suffer from exponential proliferation. Conventional PDE solvers are also inadequate, particularly at high frequencies, and/or when the propagation domain is highly heterogeneous (containing many scatterers, a highly variable refractive index or geometric singularities).

The aim of this workshop is to bring together researchers working on computational methods for multiple scattering and to explore possible connections and common challenges between the different communities involved.

Sujets:
- novel discretization techniques based on numerical homogenisation, integral equation methods, finite element methods (including Trefftz methods), and semi-analytic and generalised eigenfunction methods; - acceleration techniques including preconditioning, matrix compression (including H-matrices and the fast multipole method), domain decomposition and fast direct solvers; - robust and efficient software implementations

Workshop RNTW03 — New tomographic methods using particles
15 mai 2023 - 19 mai 2023 • Cambridge , Royaume-Uni
Organisateur:
Isaac Newton Institute for Mathematical Sciences (INI)
Résumé:
This workshop will include experts on a wide range of emerging tomographic techniques using particles including muon and muon scattering tomography, proton tomography, electron tomography, emission tomography including emission tomography for radiographic dose estimation, Compton scattering tomography and neutron diffraction tomography. Most of these tomographic modalities are non-linear and involve measurement of more than intensities. They thus require sophisticated mathematical techniques for successful imaging and the goal is to match these emerging methods with mathematicians studying integral geometry, non-Abelian tomography, Bayesian inverse problems, regularisation and related areas in an attempt to spur interdisciplinary collaboration.

Workshop MMVW02 — Collective Behaviour
07 aou 2023 - 11 aou 2023 • Cambridge , Royaume-Uni
Organisateur:
Isaac Newton Institute for Mathematical Sciences (INI)
Résumé:
Modelling collective group movement in animal ecology and cell biology has, over the years, followed two relatively parallel modelling paths. Most prevalent for the former are what one might define as discrete level models, whereby computational constructs are used to keep track of the spatio-temporal dynamics of each individual in a group. Problems in the latter, cell biology, have been tackled mostly by continuous models whereby the details of the individuals are neglected, in favour of a description of the entire population through, e.g. a density function. However, more recently hybrid agent-based/population models have gained increasing usage.

As the overall aim of the workshop is to create an overarching modelling framework with which to interpret common empirical features, the exchange of ideas and techniques from the different communities is an invaluable opportunity to move forward and at the same to delineate the boundaries of applicability of the different approaches in collective movement research.

INMS Workshop — MoDiS 2023: Modelling Diffusive Systems
11 sep 2023 - 15 sep 2023 • ICMS, Edinburgh, Royaume-Uni
Organisateur:
ICMS - International Centre for Mathematical Sciences
Résumé:
The aim of this workshop is to bring together experts from different communities to cover the investigation of diffusive systems from several viewpoints: analytically, combining methods and techniques from Partial Differential Equations (PDEs) and dynamical systems to derive and analyse mathematical models for the applied phenomena; numerically, reviewing the most recent techniques and software for the computation of bifurcation diagrams and continuation with respect to the systems’ parameters; and, last but not least, from the applied — in particular biological — viewpoint: a constant exchange of knowledge between the theoretical investigations and the experimental data is in fact crucial in order to advance the research in this area. Our speakers will illustrate the most recent advancements in these fields, and foster the creation of new research directions with a concluding description of three open research questions aimed at colleagues working in fields different from their own. This will allow researchers with different backgrounds to learn ultimate techniques, connect with experts from various areas, and collaborate with fellow participants to produce new, cutting-edge research.

Workshop MMVW03 — Measures and Representations of Interactions
11 sep 2023 - 15 sep 2023 • Cambridge , Royaume-Uni
Organisateur:
Isaac Newton Institute for Mathematical Sciences (INI)
Résumé:
The study of interactions among living entities covers broad scientific domains, ranging from molecules and cells through individual organisms and groups to species, populations and communities. Common to all domains is the need to quantify the presumed interactions at the relevant spatial and temporal scales. While no formal theory exists in the literature, there exist different approaches that aim to construct a mechanistic representation of how individuals interact with each other as well as how to measure such interactions, but in most cases such approaches are specific to the problem at hand. The common factor among the existing approaches is their intention to represent the sequential nature of how organisms interact, first acquiring information from their surroundings, then processing that information and subsequently selecting a movement response.

By cross-fertilising different ideas and techniques in animal ecology and cell biology we aim to gain a more realistic perspective on measurement and representation of organism interactions, revisiting existing concepts, and permitting new discoveries and insights.

Workshop MMVW04 — Modelling non-Markov Movement Processes
06 nov 2023 - 10 nov 2023 • Cambridge , Royaume-Uni
Organisateur:
Isaac Newton Institute for Mathematical Sciences (INI)
Résumé:
The purpose of this workshop is to bring together scientists interested in different areas of complex movement in a biological context, from field research, to data analysis, to theoretical modelling. In particular, the focus will be on complex movement beyond the Markov property, such as memory-dependent animal foraging processes, spatial avoidance due to past deposition of animal scent or resource depletion, and directed motion in neutrophils. Despite its ubiquity, the mathematical difficulty in dealing with history dependence has hampered the study of non-Markov movement processes. Past empirical limitations are also responsible for the lack of a general theory to describe history dependent movement processes, as detection of features that would distinguish between Markov and non-Markov model predictions were not attainable. Currently, movement data may reach unprecedented resolution, and there is a renewed interest in developing non-Markov movement models, exemplified by recent theoretical studies to devise general prescriptions to simulate non-Markov stochastic processes.
