16:00 - EVENT - CMCA Seminar Series: Computer-aided detection/diagnosis of breast cancer in multi-modal MRI More Information
A recent meta-study concluded that the use of computer-aided detection/diagnosis (CAD) "in breast MRI has little influence on the sensitivity and specificity of experienced radiologists and therefore their interpretation remains essential". In this talk I describe ongoing collaborative research to improve the sensitivity and specificity of breast MRI, and concomitantly its clinical utility, by combining multi-modal MRI with novel multi-parametric and multi-dimensional image analysis techniques. In particular we are developing methods to quantitatively characterise tissue morphology, microvasculature, and microstructure from spatially aligned multi-modal MR images including anatomical T1- and T2-weighted images, as well as images acquired using dynamic contrast-enhanced (DCE) MRI, and diffusion-weighted imaging. We are also developing image analysis methods to automatically extract these features, segment (delineate) suspicious tissue, and classify the tissue as benign or malignant. Results to date include a novel registration evaluation framework based on a biomechanical breast model that permits realistic simulation of tissue deformation, new spatiotemporal features for improved discrimination of benign and malignant lesions in DCE-MRI, and most recently the first fully automatic method for breast lesion detection and delineation.

15:00 - SEMINAR - Groups and Combinatorics Seminar: Homomorphisms and Endomorphisms of Graphs More Information
Time and place: 3pm Friday 6 February in Weatherburn LT.

Speaker: Gordon Royle (UWA)

Title: Homomorphisms and Endomorphisms of Graphs.

Abstract: A homomorphism from a graph X to a graph Y is a function f from V(X) to V(Y) that preserves edges (but not necessarily non-edges); if Y = X, then it is called an endomorphism. Just as all the automorphisms of a graph form its automorphism group, all the endomorphisms of a graph form its endomorphism monoid. After covering the background definitions, I will discuss a number of problems that have in common that any solution will rely on understanding - either theoretically or computationally - various aspects of the endomorphisms of the graphs involved.

16:00 - SEMINAR - Mathematics & Statistics Colloquim: The Bayesian Paradigm for Statistical Inference and Decision Making. More Information
Colloquium time date and location: 4pm, Thursday 19th February, Blakers Lecture Theatre.

Speaker: Prof. Nozer Singpurwallah, City University of Hong Kong.

Title: The Bayesian Paradigm for Statistical Inference and Decision Making.

Abstract: In this expository talk, open to a general audience, I outline the essence of the Bayesian paradigm for inference and decision making. After an overview of the subjective nature of probability, I discuss the notion of a likelihood, and the genesis of a probability model. The material here is standard, but the perspective is not. It will be illustrated by some simple examples.

16:00 - SEMINAR - The Amazing Cavitation Bubble- from Ship Propellors to Medical Supertools : This seminar is part of the Centre for Water Research seminar series. Website | More Information
We generally think of bubbles as benign and harmless and yet they can manifest the most remarkable range of physical effects. Some of those effects are the stuff of our every day experience as in the tinkling of a brook or the sounds of breaking waves at the beach. But even these mundane effects are examples of the ability of bubbles to gather, focus and radiate energy (acoustic energy in the above examples). In other contexts that focusing of energy can lead to serious technological problems as when cavitation bubbles eat great holes through ships' propeller blades or cause a serious threat to the integrity of the spillways at the Hoover Dam.

In liquid-propelled rocket engines bubbles pose a serious threat to the stability of the propulsion system and in artificial heart valves they can cause serious damage to the red-blood cells. In perhaps the most extraordinary example of energy focusing, collapsing cavitation bubbles can emit not only sound but also light with black body radiation temperatures equal to that of the sun.

But, harnessed carefully, this ability to focus energy can also be put to constructive use. Cavitation bubbles are now used in a remarkable range of surgical and medical procedures, for example to emulsify tissue (most commonly in cataract surgery or in lithotripsy procedures for the reduction of kidney and gall stones) or to manipulate the DNA in individual cells.

By creating cavitation bubbles non-invasively and thereby depositing and focussing energy non-intrusively, one can generate minute incisions or target cancer cells. This lecture will begin by ranging over some of the fundamentals of cavitation and will end with a vision of the new horizons for the amazing bubble, in the process ranging from ship's propellers to medical supertools.

Friday 06
15:00 - SEMINAR - Groups and Combinatorics Seminar, Multimarkdown and typesetting mathematics More Information
Time and place: 3pm Friday 6 March in Weatherburn LT.

Speaker: John Bamberg (UWA)

Title: Multimarkdown and typesetting mathematics.

Abstract: Markdown has been around for around a decade or so, and is a simpler alternative to xml for producing simple easy-to-read text with powerful mark-up capability. If you don't already know what Markdown is, then you really ought to know! The genius of Markdown is that it has an almost flat learning curve, and it is ideal for people who have no programming experience. It can be easily converted to RTF or HTML and is essentially platform independent. For more advanced use, there is "Multimarkdown", and yet it is still amazingly simple and intuitive. Multimarkdown can be easily converted to HTML and LaTeX, and so it has the potential to be very useful to mathematicians. This seminar is a basic introduction to this fantastic mark-up language.

15:00 - SEMINAR - Groups and Combinatorics Seminar: A non-classification theorem for 2-arc-transitive graphs More Information
Time and place: 3pm Friday 13 March in Weatherburn LT.

Speaker: Luke Morgan (UWA)

Title: A non-classification theorem for 2-arc-transitive graphs.

Abstract: It would be great to have a classification of 2-arc-transitive graphs! Sadly, this is probably out of reach. However, there are many results on classifications of 2-arc-transitive graphs of certain orders, valencies, girth, etc... In this talk, I'll describe a recent result of Eric Swartz, Gabriel Verret and myself where we do something slightly different. Rather than classify all the possible graphs, we show that for fixed n and k, the family of 2-arc-transitive graphs of order kp^n is finite, with p a prime, once the valency is big enough (relative to n). So, our "non-classification" shows that the most interesting 2-arc-transitive graphs are those of small valency (relative to n).

16:00 - SEMINAR - Mathematics & Statistics Colloquium: Complex Systems: From nonlinear dynamics to graphs, via time series. More Information
Mathematics & Statistics Colloquium

Time and date: 4pm, Thursday 19th March

Venue: Blakers Lecture Theatre

Speaker: Prof. Michael Small, The University of Western Australia.

Title: Complex Systems: From nonlinear dynamics to graphs, via time series.

Abstract: Given a deterministic dynamical system - possibly contaminated by noise - what can I say about that system by measuring the time evolution of a single state? There are standard methods to answer this question, and I will review these. I will also show that by transforming the reconstructed system into a large graph, it is possible to learn even more.
Friday 20
15:00 - SEMINAR - Groups and Combinatorics Seminar: UCS groups and associated algebras More Information
Time and place: 3pm Friday 20 March in Blakers LT.

Speaker: Frederico A. M. Ribeiro (Federal University of Minas Gerais)

Title: UCS groups and associated algebras.

Abstract: Groups having many characteristic subgroups tend to have simpler automorphism subgroups, so it might be a good idea to look into the automorphism subgroups of groups having few characteristic subgroups. While characteristically simple groups are well understood, this is not the case when "few" is greater than zero. UCS groups are groups having a unique non-obvious characteristic subgroup. When investigating one of the two classes of UCS p-groups, I, together with Csaba Schneider, showed that they could be associated bijectively with a class of algebras we called IAC (irreducible and anticommutative). We can then, by looking into properties of these algebras, gather information about the groups.

Friday 27
15:00 - SEMINAR - Groups and Combinatorics Seminar: Vertex-primitive digraphs having vertices with almost equal neighbourhoods More Information
Time and place: 15:00 Friday 27 March in Weatherburn LT.

Speaker: Gabriel Verret (University of Western Australia)

Title: Vertex-primitive digraphs having vertices with almost equal neighbourhoods.

Abstract: Apart from some very trivial examples, a vertex-primitive digraph cannot have two vertices with equal neighbourhoods. (This is an easy exercise.) The first non-trivial case is thus when a vertex-primitive digraph has two vertices with neighbourhoods differing by one. I will give a proof of the classification of such digraphs, and describe a more general result and some applications.
