SUMMARY:PGR Practise Talks (Dec\, 2021)
DESCRIPTION:The SIAM & IMA Student Chapter is organising a PGR Practice Talk\, giving PGR students the opportunity to present their work and ask for input from other PGR students. The event will be held on Thursday the 2nd of December\, from 13:00-15:50 in Room E04\, Monica Patridge Building (formerly known as Teaching and Learning building).  \n\n\n\nWe will also live stream any in person and any online talk via Teams. The link will become available on the day itself. \n\n\n\n\n\n\n\n\n\nProgramme \n\n\n\n\n\n\n\n\n13:20 Alexander Nagen: Induced Standard Model   \n\n\n\nThis talk will be about a re-formulation of the Standard Model of particle physics\, including the right-handed neutrinos\, based on induced gravity. An interesting problem is to find out how the right-handed neutrinos contribute to the Standard Model by itself. First\, some background will be outlined. Then\, the author will talk about their work on this problem. The author will conclude with problems that may be addressed in future research.  \n\n\n\n\n13:50 Adam Blakey: FEMs for Placental Haemodynamics   \n\n\n\nThe placenta provides nutrients and oxygenated blood to developing foetuses\, and is therefore vital to a foetus’ survival. I will talk about the outlook of my PhD project and present some basic computational simulations of maternal blood flow in human placentas using DG FEMs in representative 2D geometries.  \n\n\n\n14:15 Alexander Lewis: Stein’s Method on Manifold with Boundary  \n\n\n\nSince its inception\, Stein’s method has been found to provide powerful\, easy-to-construct bounds on probability metrics. At first\, Stein applied this framework for comparisons with the normal distribution\, however the field has now grown to encompass many classes of distributions on many different spaces. In this talk I will be presenting my current research on how to extend the theory of Stein’s method from Riemannian manifold to manifold with boundary.  \n\n\n\n14:40 Thomas Hall: Markov-type Diophantine Equations and their Underlying Geometry and Combinatorics  \n\n\n\nIt turns out that the Diophantine equation dxyz = ax^2 + by^2 + cz^2 is intimately linked to the behaviour of certain lattice triangles under an operation called “mutation”. In this talk\, we will explore this connection and show how to solve such an equation.  \n\n\n\n15:10 Robert Barnet: Pore-scale open-source multi-domain solvers for ionic transport and electrochemistry in electrolyte solutions  \n\n\n\nIn this work we present open-source solvers\, built upon the finite volume library OpenFOAM\, solving the Stokes-Poisson-Nernst-Planck (SPNP) model for multi-domain ionic transfer in dilute electrolyte solutions. Many real-world applications of SPNP\, such as electrochemical energy storage\, reinforced concrete  and oil extraction\, also include heterogeneous reactions exchanging mass between ionic species. As such\, alongside our solvers\, we present our formulated set of boundary conditions to model this reactive mass exchange between species\, constrained by mass and charge conservation. After outlining the governing equations we perform some dimensional analysis\, giving a qualitative description of the different possible transport regimes\, quantified by the ratios between the forces inducing ionic transport. Later we give a brief description of the numerical algorithms\, based upon the PIMPLE algorithm\, underpinning our pore-scale solvers (pnpFoam and pnpMultiFoam) and semi-Newton iterative algorithm used to solve our heterogeneous reactive conditions (mappedChemicalKinetics). We later verify\, using one-dimensional test cases\, the accuracy of our solvers and conditions. Results are compared against high-order spectral results obtained with the MatLab toolbox Chebfun. Since a large number of applications of SPNP involve complex porous geometries (e.g.\, batteries involve a porous solid electrode flooded with fluid electrolyte)\, we later consider a three-dimensional randomly generated porous domain of solid and fluid. Finally\, we present preliminary results on applying our work towards a real-world commercial battery cell (LGM50)\, with hopes to give a comparison with experimental data found in.  \n\n\n\n15:30 Niren Bhoja: Spin(10)\, Octonions and the Standard Model.   \n\n\n\nIn this talk I explore the spinor representation of Octonions on Cliff_{10} to construct the Lie algebra of the Lie group Spin(10)\, the usually agreed upon GUT of the standard model.

SUMMARY:A Good Mathematician is a Lazy Mathematician
DESCRIPTION:Title\n\n\n\nA Good Mathematician is a Lazy Mathematician \n\n\n\nAbstract\n\n\n\nI am not sure when I first heard this phrase\, I suspect it was used by one of my sixth form maths teachers\, but I have increasingly come to realise how true this is – and what is more remarkable this laziness has actually shaped the way we\, and perhaps society\, think about mathematics. \n\n\n\nThe talk will introduce me and give some background about myself and my career to provide context. The main part of the talk will explore some of the short cuts of mathematics\, and the influences they have had. Examples will include some of Euler’s thinking and ‘clock arithmetic’ and the use of logarithms pioneered by Napier\, Briggs and Oughtred. The talk will be illustrated with slides\, and there will also be some mathematical ‘props’ to show. \n\n\n\nThe talk will conclude with a brief description of some of the ways government uses mathematics\, and opportunities of engaging with this\, either as employees or otherwise. \n\n\n\nBiography\n\n\n\n\n\nEd’s professional career has been spent as a civil servant in the MOD scientific branch\, initially the Defence Evaluation and Research Agency and subsequently the Defence Science and Technology Laboratory. This followed a degree in mathematics at Loughborough University.Throughout this time Ed has evolved from a junior research scientist to an experienced leader and manager. Currently developing and growing strategic partnerships to ensure Science and Technology can create impact and prosperity across the UK. Ed is a Visiting Professor at Loughborough University.Ed is an experienced Non-Executive Director and Trustee of several charities and holds fellowships of the Institute of Mathematics and its Applications\, the Royal Aeronautical Society\, and the Royal Society for the Arts. \n\n\n\nCheck back on the day of the event for the Teams link.   \n\n\n\nThis will also be streamed in C12\, Monica Partridge Building for those on campus.

SUMMARY:Footnotes to Turing (1952): Some Modern Challenges in Pattern Formation
DESCRIPTION:Abstract\n\n\n\nMotivated by recent work with biologists\, I will showcase some mathematical results on Turing instabilities in complex domains. This is scientifically related to understanding developmental tuning in a variety of settings such as mouse whiskers\, human fingerprints\, bat teeth\, and more generally pattern formation on multiple scales and evolving domains. Some of these problems are natural extensions of classical reaction-diffusion models\, amenable to standard linear stability analysis\, whereas others require the development of new tools and approaches. These approaches also help close the vast gap between the simple theory of diffusion-driven pattern formation\, and the messy reality of biological development\, though there is still much work to be done in validating even complex theories against the rich dynamics observed in nature. I will emphasize throughout the role that Turing’s 1952 paper had in these developments\, and how much of our modern progress (and difficulties) were predicted in this paper. I will close by discussing a range of open questions\, many of which fall well beyond the extensions I will discuss\, but at least some of which were known to Turing. \n\n\n\n\n\n\n\n\n\n\n\nI grew up in New Mexico\, USA\, where I earned undergraduate degrees in Mathematics and Computer Science at the New Mexico Institute of Mining and Technology in 2012\, and a Masters degree in Mathematical Analysis in 2014. I then obtained a DPhil (PhD) in Mathematics within the Oxford Centre for Industrial and Applied Mathematics in 2018\, and continued as a postdoc in the Wolfson Centre for Mathematical Biology before becoming a Departmental Lecturer in Applied Mathematics jointly between these two groups. I left Oxford in September of this year to join the Department of Mathematical Sciences at Durham University\, where I am an Assistant Professor of Applied Mathematics.  \n\n\n\n\n\nCheck back on the day of the event for the Teams link.  \n\n\n\nThis will also be streamed in A17\, Mathematical Sciences Building for those on campus.

SUMMARY:The Mathematics of the Maya (and Other Stories)
DESCRIPTION:Watch the recording below. \n\n\n\n\n\n\n\nIn the United States\, the second Monday of October is commonly referred to as “Columbus Day”\, a holiday meant to commemorate the “discovery” of America by Christopher Columbus in 1492. However\, given the false and problematic nature of this narrative\, many Americans in recent years have begun rebranding this holiday as “Indigenous Peoples’ Day”\, to instead recognize the native people of the Americas who were impacted by imperialism and colonialism. To help honor the occasion\, we’ll be discussing the mathematical achievements of one of the oldest civilizations in the Americas\, the Maya\, who lived in southern Mexico and central America as early as 4\,600 years ago. \n\n\n\nIn this talk\, we will introduce the Maya numeral system\, which is simple enough to only require three symbols\, yet powerful enough to represent large numbers easily and efficiently. We’ll observe how to perform basic arithmetic operations in their system (such as addition and multiplication)\, as well as how to extend their system to capture mathematical ideas that the Maya may have never used (such as rational and real numbers). Then\, we’ll broaden our scope and take a brief tour of numeral systems of other civilizations throughout history and around the world\, looking at their motivations\, benefits\, and disadvantages. By studying these numeral systems comparatively\, we can improve our understanding of our own system of numbers\, appreciate what makes the Maya system unique and useful to this day\, and gain a deeper understanding of civilizations and cultures\, past and present. Also\, if time permits\, we will see what makes the number 252 special. \n\n\n\nThis talk is intended for people of all mathematical backgrounds. No prerequisite knowledge is required. \n\n\n\n\n\n\n\n\n\n\n\nHakim is a Preceptor in the Department of Mathematics at Harvard University\, where he primarily teaches undergraduate students. Originally from New York City\, he attended graduate school at the George Washington University in Washington\, D.C.\, earning his Ph.D in mathematics in 2017. Although his main research areas were in logic and computability theory\, Hakim’s academic interests also include number theory\, recreational mathematics\, philosophy\, the history of mathematics\, and mathematics/STEM education.

SUMMARY:Understanding Sensory Induced Hallucinations: From Neural Fields to Amplitude Equations
DESCRIPTION:Explorations of visual hallucinations\, and in particular those of Billock and Tsou [Neural interactions between flicker-induced self-organized visual hallucinations and physical stimuli.  Proceedings of the National Academy of Sciences\, 104(20):8490-8495\, 2007]\, show that annular rings with a background flicker can induce visual hallucinations in humans that take the form of radial fan shapes. The well-known retino-cortical map tells us that the corresponding patterns of neural activity in the primary visual cortex for rings and arms in the retina are orthogonal stripe patterns. The implication is that cortical forcing by spatially periodic input can excite orthogonal modes of neural activity.  Here we show that a simple scalar neural field model of primary visual cortex with state-dependent spatial forcing is capable of modelling this phenomenon.  Moreover\, we show that this occurs most robustly when the spatial forcing has a 2:1 resonance with modes that would otherwise be excited by a Turing instability.  By utilising a weakly nonlinear multiple-scales analysis we determine the relevant amplitude equations for uncovering the parameter regimes which favour the excitation of patterns orthogonal to sensory drive.  In combination with direct numerical simulations\, we use this approach to shed further light on the original psychophysical observations of Billock and Tsou. This is joint work with Abigail Cocks\, Stephen Coombes\, Alan Johnston (Nottingham\, Psychology) and Daniele Avitabile (VU Amsterdam)  \n\n\n\nWatch the recording below.

SUMMARY:Mathematicians at War
DESCRIPTION:Abstract\n\n\n\nBritish mathematicians responded to the First World War in a variety of ways.  Some volunteered their mathematical skills for work at the Royal Aircraft Factory where they could experience the risky practice of flying\, while others went to the National Physical Laboratory where\, safely on the ground\, they did experiments using wind tunnels.  Another group joined the Anti-Aircraft Experimental Section of the Ministry of Munitions where they worked on ballistics.  There were also those who followed a military path\, and those who\, for reasons of conscience\, refused to take an active part in the War.  In this talk I’ll discuss the war-time activities of a number of British mathematicians\, and examine the impact of the War on their careers as well as on mathematics itself.

SUMMARY:Convergence Properties of Dynamical Energy Analysis — A Ray-based Method Using Transfer Operators
DESCRIPTION:Describing the distribution of vibrational energy in real world applications is challenging\, especially in the mid-to-high frequency regime. A very promising way is using densities of rays and creating a transfer operator T by a method called Dynamical Energy Analysis. This has been used in a range of real-world scenarios ranging from gear boxes over car bodies to whole ship hulls. \n\n\n\nThe role of this operator T is to propagate the intensity of the vibrational excitation across a given structure. Using local properties of the structure\, this propagation can account for different material properties and geometrical aspects. For thin shells for example\, it describes the vibrations in terms of pressure\, shear\, and bending wave modes. \n\n\n\nIn order to compare predictions with experimental data this tool has to be used numerically. This makes it necessary to represent T in terms of a finite basis. To have an efficient implementation with a good convergence and small errors it is necessary to choose an optimal set of basis functions. The talk will cover convergence properties of this method as well comparing them with a simple analytical model.

SUMMARY:Multiscale and Multiphase Models of Tissue Growth\, Remodelling and Mechanics
DESCRIPTION:Understanding biological tissue growth and mechanics is of fundamental importance to a wide range of diseases and biomedical applications. In this talk I will attempt to summarise (too briefly\, probably) an optimistically large set of continuum-mechanical modelling approaches and experimental investigations that aim to shed light on some of these processes in the context of tissue engineering and asthma. The former refers to techniques where tissue is grown in vitro for implantation\, or stimulated in vivo at the injury site; the latter is multi-phenotypic disease varying in severity\, and underpinned by inflammation\, airway contraction\, and airway remodelling. The mathematical and computational approaches exploit multiphase modelling\, hyperelastic soft tissue mechanics\, and asymptotic homogenisation and model reduction approaches\, while experimental approaches include with 3D printing\, in vitro cell culture\, and mechanical testing and image analysis of data from experiments in mice.

DESCRIPTION:Abstract\n\n\n\nThe CICE sea ice model is used extensively by climate and Earth system research groups\, and also by operational centers for applications such as numerical weather prediction and guidance for military operations.  This presentation introduces the physics represented by large-scale sea-ice models\, discusses some of the challenges in applying sea-ice modeling tools developed for research purposes for operational forecasting on short time scales\, and highlights promising new directions in sea-ice modeling. The thread running through this discussion relates to the complexity needed to meet common yet distinct sea ice modeling objectives among different communities.

SUMMARY:Multiscale Approaches for Heart Perfusion
DESCRIPTION:Microcirculation and perfusion exemplify the mesoscale in physiological systems\, bridging larger and smaller scale phenomena. Multiscale mathematical models represent a valuable tool to investigate and understand such phenomena\, where a brute force computational approach is not viable yet. For microcirculation accurate models must comprise both interstitial and vascular compartments\, along with their complex morphology. Transport phenomena across the vascular wall couple these two main compartments. In addition\, several nonlinear effects are required to properly model microvascular flow. \n\n\n\nWe apply this framework to human cardiac perfusion\, developing a model that accounts for the different length scales of the vessels in the coronary tree. Epicardial vessels are represented with fully three-dimensional (3D) fluid-dynamics\, whereas intramural vessels are modeled as a multi-compartment porous medium. The coupling of these models takes place through interface conditions based on the continuity of mass and momentum. To estimate the physical parameters of the multi-compartment model\, a virtual intramural vascular network is generated.

SUMMARY:Stochastic Modelling for Weather and Climate Prediction
DESCRIPTION:Atmospheric models used for weather and climate prediction are traditionally formulated in a deterministic manner. In other words\, given a particular state of the resolved scale variables\, the most likely forcing from the sub-grid scale motion is estimated and used to predict the evolution of the large-scale flow. However\, the lack of scale-separation in the atmosphere means that this approach is a large source of error in forecasts. Over the last decade an alternative paradigm has developed: the use of stochastic techniques to represent small-scale processes. These techniques are now ubiquitous in weather and seasonal forecasting centres worldwide. However their formulation remains ad hoc\, with little evolution in operational schemes since the earliest approaches. In this presentation I will consider the challenge of developing stochastic parametrisation schemes that skilfully mimic unresolved\, small-scale processes\, and the potential of very high-resolution simulations to indicate the form that stochastic schemes should take. I will conclude by discussing experiments in two climate models that demonstrate the potential for improving climate simulations by using stochastic approaches.
