SUMMARY:AARMS COVID-19 Seminar:  Tom Hurd (McMaster)
DESCRIPTION:From Agent Based Infectious Disease Models to Compartment Models\nThere are lots of potential agent based approaches to COVID modelling\, and it is of interest to try to connect them to more standard compartment ODE models. To what extent can any ODE model capture the properties of a given ABM? The Inhomogeneous Random Social Network (IRSN) framework I have developed recently provides an explicit setting where such questions can be explored mathematically. The IRSN approach starts with a finite number N of heterogeneous agents that interact according to \ AB type rules. Under some conditions\, one can analyze their large N limit\, and under even more conditions\, derive a limiting standard stratified compartment ODE model. The IRSN framework can be made arbitrarily fine-grained in many dimensions\, including demographic classification\, immunology (multiple variants)\, contact settings (types of contact locations) but only certain combinations of features are relevant to the ODE limit. ABMs capture characteristics such as non-homogeneous mixing that are not easily captured in any ODE model\, so they help to understand the impact of such characteristics on disease propagation. \nIRSN Model Paper: https://www.sciencedirect.com/science/article/pii/S2468042720300713 \nMore information about this seminar series.  This is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.  All times are given in the Atlantic timezone.

SUMMARY:AARMS COVID-19 Seminar:  Madeleine Gorman-Asal (University of New Brunswick Fredericton)
DESCRIPTION:Using a Mathematical Model to Investigate the Efficacy of Asymptomatic Testing to Detect SARS-CoV-2\nA mathematical model was constructed to investigate the efficacy of asymptomatic testing for SARS-CoV-2 detection. Preliminary data suggests that the stage of disease at the time of testing impacts its efficacy. The probability of being detected by the asymptomatic test was compared by the number of days waited until taking the test since arrival given the unknown state of disease at arrival\, the variability of the infectious period and whether case detection efforts were undergone prior to arrival. It was found that if assuming an equal probability of being in the incubation stage or an asymptomatic infectious stage\, waiting until the fifth day since arrival to be tested is the earliest testing date that results in more detected than undetected cases. Additionally\, in the 50% of COVID-19 cases with an infectious period longer than 22 days\, there are limited differences in the probability of being detected when tested within the first 2\, 5 or 8 days since arrival. \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.  All times are given in the Atlantic timezone.

SUMMARY:Groups acting on Trees: minicourse by Olga Kharlampovich
DESCRIPTION:From May 3\, 2021 to May 7\, 2021\, Professor O. Kharlampovich from City University of New York will teach a mini course on Groups acting on Trees. Due to the current situation caused by the corona virus disease\, the mini course will take place virtually. \nBass-Serre theory relates group actions on trees with decomposing groups as iterated applications of the operations of amalgamated product and HNN extension\, via the notion of the fundamental group of a graph of groups. \nOne of the generalizations of Bass-Serre theory is the theory of isometric group actions on real trees (R-trees) which are metric spaces generalizing the graph-theoretic notion of a tree. Group actions on R-trees arise naturally in geometric topology\, as well as in geometric group theory. Asymptotic cones of groups often have a tree-like structure and give rise to group actions on real trees. The use of R-trees and $\Lambda$ -trees\, in particular Zn-trees\, together with Bass-Serre theory\, are key tools in the work on the elementary theory of a free group by Kharlampovich-Miasnikov and Sela. \nThe course will be suitable for undergraduates\, graduate students\, postdocs\, faculty\, and anyone interested in algebra. The internet address for the virtual meeting room will be available at https://www.mun.ca/aac/AACMiniCourses/olga/ \nThe mini course will take place from 10 to 10:50 Eastern Standard Time.

SUMMARY:AARMS COVID-19 Seminar:  Ahmed Saif (Dalhousie)
DESCRIPTION:A Simulation-Optimization Framework for Optimizing Response Strategies to Epidemics\nEpidemics require dynamic response strategies that encompass a multitude of policy alternatives and that balance health\, economic and societal considerations. We propose a simulation-optimization framework to aid policymakers select closure\, protection and travel policies to minimize the total number of infections under a limited budget. The proposed framework combines a modified\, age-stratified SEIR compartmental model to evaluate the health impact of response strategies and a Genetic Algorithm to effectively search for better strategies. We implemented our framework on a real case study in Nova Scotia to devise optimized response strategies to COVID-19 under different budget scenarios and found a clear trade-off between health and economic considerations. Closure policies seem to be the most sensitive to budget restrictions\, followed by travel policies. On the other hand\, results suggest that practicing social distancing and wearing masks are necessary under all scenarios. The framework is generic and can be extended to encompass vaccination policies and to use different epidemiological models and optimization methods. \nAhmed Saif\, Ph.D.\, P.Eng.\, is an Assistant Professor in the Department of Industrial Engineering at Dalhousie University. He received a Ph.D. in Management Sciences from the University of Waterloo\, an M.Sc. in Engineering Systems and Management from Masdar Institute of Science and Technology\, an MBA from New York Institute of Technology and a B.Sc. in Production Engineering from Alexandria University. Prior to joining Dalhousie University\, he spent a year as a Postdoctoral Fellow in HEC Montréal. He also has several years of experience in engineering and consulting companies in Canada and abroad. Dr. Saif’s research focuses on large-scale optimization\, decision making under uncertainty and data analytics methods and their applications in hybrid renewable energy systems and sustainable supply chain problems. His research has been funded by various agencies including NSERC and MITACS\, and has been published in high-impact journals\, including INFORMS Journal on Computing\, Computer & Operations Research \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.  All times are given in the Atlantic timezone.

SUMMARY:Atlantic GR Seminar: Dr Robie Hennigar (MUN)
DESCRIPTION:Holographic Complexity and Thermodynamic Volume\nI will discuss recent work exploring the holographic complexity conjectures for rotating black holes. A relationship between the complexity of formation and the thermodynamic volume of the black hole is found\, and I discuss the evidence that suggests this relationship holds generally. This is one of the first connections between thermodynamic volume and holography\, and I will discuss possible implications. \nThe Atlantic General Relativity 2020 online postdoc/student seminar series is in the tradition of the annual AGR meetings\, providing a forum not only for students and postdocs to present their research and make professional contacts but also to facilitate connections and collaborations between all Atlantic Canadian relativists. The series is student-organized and includes all areas of classical and quantum gravity. Talks will occur on the last Wednesday of every month\, with each session consisting of two 30 minute talks. If you would like to attend\, please email the organizers for connection details. \nNote: all times are Atlantic Time

SUMMARY:AARMS COVID-19 Seminar: Ting-Hao Hsu (UNB)
DESCRIPTION:Slow-Fast Systems in Epidemic Models\nDifferential equations involving slow and fast time scales have been adopted in mathematical modelling to capture rapid changes occurred in the epidemic systems. Examples include outbreaks of infectious diseases and autonomous behavioural changes of individuals. I will introduce a new technic in slow-fast systems to analyze relaxation oscillations\, i.e.\, periodic orbits with slow and fast segments\, in such models. The approach is based on extending the so-called entry-exit function to multi-dimensional slow-fast systems using the geometric singular perturbation theory. \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.  All times are given in the Atlantic timezone.

SUMMARY:AARMS COVID-19 Seminar: James Watmough (UNB)
DESCRIPTION:Case importation and community spread: post-pandemic control of the spread of SARS-CoV-2 in low density populations\nIt has been just over one year and 100 million cases since we first heard of a novel coronavirus with pandemic potential. We are now all far too familiar with epidemic curves and would very much like to see the tail of this one. In this talk\, I will review the simple mathematical models for the transition from pandemic to endemic and what they tell us about this tail. \nFor the past year\, Canada has kept case numbers relatively low through a combination of community quarantine and travel restrictions. In theory\, this has implications for how we approach and manage the new normal of endemic SARS-CoV-2. I will focus on what this might mean for Atlantic Canada. \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.  All times are given in the Atlantic timezone.

SUMMARY:Atlantic Graph Theory Seminar: Dr. Gary Gordon\, Lafayette College
DESCRIPTION:Permutations of finite subsets of R^2 generated by Euclidean distances\nGiven a finite set of points S = {P1\, P2\, . . . \, Pn} and a vantage point V\, generate an ordering of the points of S by measuring the Euclidean distance from V to each of the points of S\, ordering them from nearest to farthest. As the vantage point moves around the plane\, different orderings will be generated. We are interested in the maximum\, minimum\, and intermediate values achievable for different point-sets S. (Good and Tideman solved the maximum problem in all dimensions in the 1970s.) We also consider a generalization that uses two vantage points\, using the average distance (d(V1\, Pk) + d(V2\, Pk))/2 to the points of S to generate an ordering. \nThe Atlantic Graph Theory Seminar series will take place every Wednesday from 3:30-4:30 ADT online via zoom. The talks\, provided by researchers\, postdocs and graduate students\, will be on a variety of current topics in graph theory. If you would like to give a talk or attend\, please email one of the organizers (Jason Brown and Danielle Cox).

SUMMARY:Atlantic GR Seminar: Sarah Muth (MUN)
DESCRIPTION:Marginally Outer Trapped (Open) Surfaces in 4+1 Dimensional Schwarzschild\nIn the case of binary black hole mergers\, the surface of most obvious interest\, the Event Horizon\, is often computationally difficult to locate. Instead\, it is useful to turn to quasi-local characterizations of black hole boundaries\, such as Marginally Outer Trapped Surfaces (MOTS)\, which are defined for a single time slice of the spacetime\, and the outer-most of which is the apparent horizon. In this talk\, I will describe ongoing work focused on understanding MOTS in the interior of a five-dimensional Schwarzschild black hole. Similar to the four-dimensional case previously studied\, we find examples of self-intersecting MOTS with an arbitrary number of self-intersections. This provides further support that self-intersecting behavior is rather generic. I will also briefly discuss the next stage of our research\, which involves further examples of these self-intersecting MOTS\, this time in the full Kruskal extension of Schwarzschild. \nThe Atlantic General Relativity 2020 online postdoc/student seminar series is in the tradition of the annual AGR meetings\, providing a forum not only for students and postdocs to present their research and make professional contacts but also to facilitate connections and collaborations between all Atlantic Canadian relativists. The series is student-organized and includes all areas of classical and quantum gravity. Talks will occur on the last Wednesday of every month\, with each session consisting of two 30 minute talks. If you would like to attend\, please email the organizers for connection details. \nNote: all times are Atlantic Time

SUMMARY:AARMS COVID-19 Seminar: JC Loredo-Osti (Memorial)
DESCRIPTION:Covid-19 management in Newfoundland and Labrador\nAtlantic Canada and the territories have experienced a qualitatively different COVID-19 epidemic than the other Canadian provinces. The question is\, do these differences suggest different best approaches to public health policy or they are just the consequence of geographic/demographic conditions? When infection prevalence is low\, imported infections are not only a large fraction of all infections\, but a major trigger of outbreaks. This also posses questions about the merits of travel restrictions as well as the escalation of measures in response to outbreaks. On this presentation\, we will discuss some of the ways to quantify these issues in the context of the pandemic in Atlantic Canada\, and in particular in Newfoundland and Labrador. \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.  All times are given in the Atlantic timezone.

SUMMARY:Atlantic Graph Theory Seminar: Dr Anthony Bonato\, Ryerson University
DESCRIPTION:The localization game played on graph\nGraph searching investigates combinatorial models for the detection or neutralization of an adversary’s activity on a network. One such model is the localization game\, where pursuers use distance probes to capture an invisible evader. We present new results on the localization number of a graph\, which is the minimum number of pursuers needed to capture the evader. We survey what is known and unknown for the localization number\, discuss connections with the chromatic number\, and give bounds on graph families such as hypercubes\, incidence graphs of combinatorial designs\, and Kneser graphs. \nThe Atlantic Graph Theory Seminar series will take place every Wednesday from 3:30-4:30 ADT online via zoom.

SUMMARY:AARMS COVID-19 Seminar: Sanjeev Seahra (UNB)
DESCRIPTION:COVID-19 modelling in New Brunswick and elsewhere\nWe present a simple differential equation based model of the COVID-19 pandemic that allows for time-evolving social distancing.  We apply the model to the first 80 days of the pandemic in 24 different jurisdictions to quantify the effectiveness of government lockdowns in March 2020.  Using Bayesian methods\, we then estimate model parameters relevant to the current outbreak in New Brunswick. \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.  All times are given in the Atlantic timezone.

SUMMARY:Atlantic Graph Theory Seminar: Dr. Hugh Thomas\, UQAM
DESCRIPTION:Dynamical algebraic combinatorics and independence sets of graphs\nDynamical algebraic combinatorics is a relatively new (and fun!) topic\, which looks at cyclic group actions on objects from algebraic combinatorics\, inspired by some questions coming from dynamical systems. I will give an introduction to the area\, focusing on an action I have defined with Nathan Williams on the independent sets of a graph (arXiv:1805.00815). We also construct a partial order on the set of independent sets of a graph\, which may be of independent interest. \nThe Atlantic Graph Theory Seminar series will take place every Wednesday from 3:30-4:30 ADT online via zoom. The talks\, provided by researchers\, postdocs and graduate students\, will be on a variety of current topics in graph theory.

SUMMARY:Atlantic Graph Theory Seminar: Dr Stephen Finbow\, Saint Francis Xavier University
DESCRIPTION:The γ-graph of a graph\nFor a graph G = (V\, E)\, the γ-graph of G\, G(γ) = (V (γ)\, E(γ))\, is the reconfiguration graph whose vertex set is the collection of minimum dominating sets\, or γ-sets of G\, and two γ-sets are adjacent in G(γ) if they differ by a single vertex and the two different vertices are adjacent in G. The γ-graph of G was introduced by Fricke et al. in 2011 where they studied properties of γ-graphs\, and raised seven questions. In this seminar we will discuss the study of γ-graphs to date with a focus on the progress of these questions. \nThe Atlantic Graph Theory Seminar series will take place every Wednesday from 3:30-4:30 ADT online via zoom. The talks\, provided by researchers\, postdocs and graduate students\, will be on a variety of current topics in graph theory.

SUMMARY:AARMS COVID-19 Seminar: Ali Gharouni (McMaster)
DESCRIPTION:COVID-19 Outbreak Dynamics and Testing-Isolation Efficacy; Insights from a Simple Epidemic Model\nOne of the main challenges in understanding COVID-19 dynamics is to estimate changes in the total level of infection in a population. The daily case count is a highly accessible form of data where observations are driven by two types of processes: (i) epidemic processes and (ii) testing processes. The challenge is then to separate these processes and understand how they interact. We developed a model that incorporates mechanistic processes of epidemic processes and testing. We have used the model to study the potential\neffect of testing strategies on disease dynamics. In future work\, we will develop improved methods for estimating true incidence by using data from negative as well as positive tests. \nIn collaboration with: Fady Abdelmalek and Drs Benjamin M Bolker\, Jonathan Dushoff\, David JD Earn \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.  All times are given in the Atlantic timezone.
