Three belt buckles, silver, bronze, and black, are all engraved with the aperiodic hat tile pattern such that the tile in the centre is fully coloured in, but the surrounding tiles are not, giving a cracked dry land look in the background.
Crochet project that looks like a cloth strip a little too thin for a scarf. The pattern is of red and white alternating zigzag patterns on both sides, done using an "interlocking" crochet style.
Blue-green socks with dice on them are on display next to a pair of sports shoes, all underneath a round table with a laptop showing presentation slides.
Picture of speaker, interpreter and slide indicating an optimisation directive to reduce testing dimensions, as there is 4096 total combinations to consider.
Presentation slide of a female Star Trek character holding a megaphone and shield, with text "Leadership Directive, the Captain's log of accessibility leadership: Plotting, briefing, protecting and reporting". Michelle is on the right on the podium, and an Auslan interpreter in the middle.
Sarah and Jennison are sitting comfortably on lounge chairs under the screen showing Jennison's face. Auslan interpreter on the right.
Picture of stage from the audience. Giant screen on the left with captions at the top. In the middle is an Auslan interpreter, on the right is the podium with who I assume is one of the organisers.
Selfie with only the top half of my head with my eyes looking upwards towards a screen showing directions to the Quiet/Sensory room at the Melbourne Conference & Exhibition Centre.
A response from "linda.mciver" says "the only relevant question is: might it make your life better by signalling your disability? if the answer is yes (looks like it to me!) then get one." I reply with "I love this perspective, thank you 🙏 For the most part I get by fine (going by past experiences) but there are definitely many small moments where it's like "Okay I just need a little more consideration when you interact with me" and I definitely don't have an issue signalling that." She responds: "yep, I get it! We CAN get by without, so we feel like we SHOULD. But it's also worth bearing in mind that it helps the people we're interacting with, too, because the interaction goes better if we understand each other better. It helps everyone and harms no one!"
Selfie of me wearing said shawl. The red bordering creates an interesting clear divide down the middle when I pull the corners together.
A pair of knitting needles with a small red and white swatch sits on top of a crocheted and stiffened red/white/black yawn bowl, containing a ball of red yarn and a ball of white yarn. Around the yawn bowl is a messy desk.
Text on whiteboard. In blue "Solving the Painleve equations would make the pain leave, eh?" Underneath in green I asked "Does this pun work?" Someone else wrote in black underneath "It gives me more pain."
Picture of a chicken thigh breast covered in panko breadcrumbs in a container next to a stove where two other breaded cutlets are being shallow fried at varying degrees of completion.
A screenshot from Melodyne showing the letter names of notes on the left. Short waveforms indicating the notes played are organised cleanly in the rows corresponding to the notes that they represent, with very little wobbling/variation in pitch from the original note.
A lace crochet that looks like two seashells coming out from the same middle spiral.
A redrawing of the problem in the quoted post, with an added "Not to perfect scale!"
A seashell-like lace crochet with its accompanying 1.4mm hook & 2ply Egyptian cotton yarn placed on top of a black background.
A spool of 2 ply white linen stands next to a small web-like circle of a lace crochet project that is reminiscent of lace table cloths. A 5 cent coin is placed below the project, indicating that the current project is about three 5 cent coins long in diameter, and the corresponding hook is about six 5 cent coins in length.
Picture of a red, white and black crochet yarn bowl on top of a messy desk. The colours are in a spiral pattern at the base, and along the sides, and the colours move between dark/light shades.
A multi-red crochet invention sits snugly on the right with a green crochet hook poking out of it. On the left is a messy tangle of 8ply acrylic wool draping from a crocheted light blue granny bag.
Black and white rendering of a guy in a business suit holding an axe.
Matt is sitting in a lecture theatre holding up his conference lanyard looking at it questioningly while he waits for the opening speech to start.
Media photo of Eddie Marsan, smiling and looking slightly above the camera. He has some beard growth compared to his other clean shaven images.
Picture of whiteboard, red ink. A person on the left is holding a bazooka shooting towards the front right. Coming out of the bazooka is a pair of disembodied muscular arms and chest ready to give a big strong comfy hug. A caption under the arms say "It's huggin' time!"
A circle coaster made from 8ply acrylic yarn. Two different colours, red and dark red, spiral out from the center. The coaster sits atop a larger lighter brown coaster for contrast, which is sitting on top of a darker brown wooden dining table.
An animation of a GeoGebra program demonstrating how the sine of an angle within a unit circle (a circle of radius 1) is linked to the y-value of the sine wave.
A desk mounted arm holds a wooden ring trapping some aida cloth which has various shades of blue speckled all over it in some interesting curvy pattern. Also on the aida is a needle minder with the word 'FUCK' in all capitals imprinted atop some flowers. In the background is a Blue Yeti mic mounted on a separate arm, and three monitors of which two is showing Facebook and Discord.
In addition to the greyish wide brimmed hat, Matt is wearing a white shirt with a purple highlight inside the collar.
A light blue crocheted granny bag with a diagonal pattern that looks like multiple R's stacked diagonally. Two half circle handles are attached and standing up at the top.
Handdrawn visual of the extracellular actin scavenging system. On the top left is cells releasing actin (indicated as green lines with blocks). On the top right is a cross section of an arm or leg, releasing Gelsolin (indicated as G), that attach to, break down, and cap actin.
Sketch of a three panel comic. First panel entitled "Before presentation" where I'm depicted as having nasty thoughts and feeling depressed. Second panel is entitled "During presentation" where I'm in my element explaining complicated stuff and a person in the corner is holding up a sign saying 10/10. Third panel is entitled "After presentation" where I'm lying on the ground exhausted and my soul is leaving my body.
Bronwyn is standing on the bottom left looking up at her title slide. There are five other collaborators on this research.
Presentation slide with title: Simulation of 1-dimensional diffusion with Neumann boundary conditions. The graphs are as described in the post.
Presentation slide with title: Couple patches to simulate the macroscale dynamics. The main diagram shows small patches with blue and orange lines joining various edges to indicate the coupling.
Presentation slide with title: Construct a 2-dimensional macroscale solution across space. A diagram of repeated grids indicate the patches, with red axes indicating the larger macroscale domain.
Presentation slide with title: Equation free macroscale modelling. Giving a general overview. Github repository for Judy's code can be found at https://github.com/uoa1184615/EquationFreeGit
Presentation slide with title "The need for macroscale modelling". Macroscale modelling describes any method which produces a macroscale solution from a problem which is defined on a microscale, reaching a compromise between accuracy and efficiency.
Judy is standing on the left with Tony introducing her. The slide contains what looks like a purple-pink crinkled piece of paper sloping downwards.
Presentation slide with subtitle: SIRS model of immune response which clarifies some of the details behind the SIR model, including the fact that after recovery there is some infection against future strains i.e. partial cross-strain immunity.
Presentation slide with subtitle: SIRIR model of strain-specific immunity, where the second I term is a repeat infection, and the second R term is resistant/immune. Graphs show that the dynamics are similar to those seen in high-burden settings e.g. remote communities in the NT
Presentation slide: Multi-strain agent-based model of Strep A transmission. The model itself is a stochastic agent-based model capturing mild infection (no sequelae, no infection site structure). There are different hypotheses for the strain-specific and cross-strain immune response.
A visual diagram of the three types of cells and interactions between them. In the bottom left is a box with three differential equations.
Presentation slide with a visual of what bistability looks like, in abstract mathematical form. The second dot point says "If you have multiple basins of attraction, then small changes in initial condition causes big changes in outcome."
Presentation slide showing visual of the details mentioned in the post.
Presentation slide showing the process of CAR T-cell therapy, which involves extracting T-cells from cancer patients, growing them in the lab, and then reinjecting them into patients to kill cancer cells.
Presentation slide showing 5 different cell states with various mathematical symbols and equations on them and the arrows between them.
Presentation slide with title: What is the Theoretical Systems Biology group doing? There are accompanying images pertaining to what is mentioned in the post.
