Whoa, after more than a year of work (the last 2 months were quite brutal), I submitted my (applied math) Master's thesis 'Computational analysis in neuroscience':

#PhD Position (f_m_x) – Uncertainty Analysis of Coupled Reactive Transport Models
Deadline: 2025-05-27
Location: Germany, Potsdam, Brandenburg
I cannot think of an applied mathematics that is more beautiful and far-reaching, or philosophically wilder, than probability. No, nonlinear dynamics and chaos people, it’s not even close

We’re having a #Soliton sale over here! Get yours quick! Seriously, though, this is a quick #animation of the #SolitonInteraction surface – the solution of the #Korteweg-deVries #Eauation showing (x,t,u(x,t)) giving you an all-round view.

I posted on #Soliton interactions in the #Korteweg-deVries #Equation yesterday with an #Animation of how two #SolitaryWaves interact. The #PhaseShift experienced by both can also be seen in a static #3D plot with time, t, plotted on one axis. You should be able to see a “dog-leg” in the trajectory of each wave after it interacts with the other.
Continued thread
A subtlety probably difficult to spot in the animation is that the interaction of the two waves leaves them phase shifted, with the taller wave gaining position, while the shorter one loses it. This further animation shows the interactions again (purple) but I’ve also shown what would happen if each wave moved without interaction with the other (red and blue).

Here is an example taken from Solitons: an introduction by Drazin & Johnson, where taller wave overtakes a shorter one moving in the same direction.

When you start looking at #NonlinearWaves, some of these principles no longer apply. For example, in the Korteweg-de Vries equation, which has #Soliton or solutions, you can no longer simply add two solutions together as the resulting function would not be a solution of the governing equation. Waves of different heights travel at different velocities, with the taller waves moving faster than the shorter ones. Instead, they interact #nonlinearly.

Also, waves of different heights travel at different velocities, with the taller waves moving faster than the shorter ones.

In #FluidMechanics, things like #SurfaceWaves are often modelled using #LinearEquations, which give rise to phenomena such as the principle of #LinearSuperposition, where you can take two or more distinct solutions and simply add them together to get a new solution. Solutions are also periodic and can be decomposed into sinusoidal functions.

“My PhD was all about understanding what happens to blood flow in collapsible blood vessels like the giraffe jugular vein. In my postdoc I was investigating how to optimise ventilator settings for patients in ICU and then how to deliver inhaled therapies into the lungs. Since then, my focus has been in trying to understand how diseases like Asthma and other respiratory diseases originate and then progress. This involves incorporating biology and physics into mathematical and computational models, using approaches from different areas of applied maths. More recently I have started to look into the mechanisms that could lead to a rare lung disease called lymphangioleiomyomatosis (LAM) and Long Covid.” - Bindi Brook

#PHD POSITION IN SPATIO-TEMPORAL MULTI-CRITERIA DECISION ANALYSIS FOR INFORMED DECISION-MAKING 100 %
Deadline: open until filled
Location: Switzerland, Winterthur
“Since my goal was to solve a problem no one had ever solved before, it required a creative and flexible approach, one that emphasized the exploration, experimentation, and steady refinement of ideas. But perhaps the most important lesson I learned was that there is no single “correct” way to be a mathematician.” - Katy Micek

(Applied?) maths terminology question:
In the context of signal analysis (doing things like Fourier transforms) you might have some variable (say, t) that you're treating as being equivalent to time and you're interested in some periodic function of t (say, sin(t)) with wavelength 2pi on the t scale.
It's common to (informally?) use the term "phase" to refer to the value of t within the first cycle of the periodic function. In that usage: phase = t modulo 2pi
By extension, I have seen people refer to location anywhere on t (not just the first cycle) as "phase", but this seems to me to be ambiguous, and not necessarily helpful, terminology.
My question is: Given that the variable t is possibly something much more abstract and not necessarily "time", is there some accepted terminology for referring to the variable t in this context?
(This is possibly a non-issue for pure mathematicians because they might never talk about phase and use only symbolic representations without using descriptive words. If so, I would be seeking terminology from some applied discipline where this kind of generic descriptive labelling is used.)
In brief, if I wanted to say:
phase = x modulo 2pi
because I am talking about periodic functions of x, is there some generic descriptive term for variables like x (e.g. time-like)?

“I love being able to apply mathematical thinking to problems perhaps not thought of as classical mathematical problems...I could not have predicted the path that I’ve been on, and certainly would never say that I had a plan all along. I am happy to do lots of different things, but it matters a lot to me who I spend my time with.” - Michelle Snider
“(...) My students have used their knowledge to model the oil spill in the Gulf of Mexico, analyze income inequality in New York City using the Gini coefficient, and determine appropriate drug dosages, among other projects. These projects not only deepen their understanding of mathematical concepts but also highlight how mathematics can be a powerful tool for analyzing and solving real-world problems. By exploring the intersection of social justice and mathematics, students gain a broader perspective on how their skills can contribute to meaningful change in society.” - Mónica D. Morales-Hernández
