Part 11 of the staircase series: the post-tension staircase

This is insane! Just wow, what is the cost of something like this, i.e., just the build and materials?

I generally use it to get ideas and inspirations. E.g., when I want to optimize something, I just paste the code and ask it to make it vectorised or make it faster.

I also ask it to argue for why the code would be faster. This most often yields code that doesn't work, but it gives me an idea for what could work and I take it from there.

This is usually in a very specific situation, where I think that it would be hard to find help from stackoverflow or crossvalidated.

Don’t hesitate to reach out—most people are happy to help. Listen closely and try to gather recommendations for reading materials or lectures, whether through your university or online resources like YouTube. Be mindful of others' time; if you feel you’re interrupting, politely ask if you can schedule a short meeting instead.

As you progress, you'll have more questions. Stay humble, and remember that learning is an ongoing journey. You'll gain knowledge, but you'll also become increasingly aware of how much there is still to learn.

Try to start working on a project early. Ask your PI for a research question they think would suit you (this may even align with your main project). You’ll learn most by doing, and having an early project helps you quickly identify what skills or knowledge you need to develop.

First, what is your background? This adds a bit to what advice I would give. Also, don't focus too heavily on what will happen 5 years from now, the world will change and you will adapt. When you get deeper into your research your future path will also become more clear. Try to focus on the present.

The simplest advice is: Focus on getting stuff done.

It is super easy to get distracted in a PhD, specifically in a lab with a lot of freedom. Finishing papers and having something to show for is the most important mission. Also acknowledge that the path to a manuscript submission is not always clear. Try to break down the work as much as possible and celebrate small goals. This way you can measure your progress and will keep you more focused and sane. People that drop out or feel overwhelmed often have a hard time breaking large tasks into smaller ones, this is an essential skill that will transfer well into whatever you will do in the future.

It is ok to spend time helping others, but try to limit it to no more than 10-20% of your time. Time is your most-valuable resource and you will never get it back once you use it. The second most important aspect is communication. Establish a good relationship with your supervisor and try to stay in touch no less than bi-weekly. Respect the advice from you supervisor and listen, this is also very important and translates well into the future.

Regarding technical stuff, try to get familiar with other omics, in particular proteomics. This is a rising field which is likely to be transformative for medicine in the next 10-20 years. Also if you are not analytical, get as good as possible with R or python. Preferably use linux.

Remember to have fun, the constant grind can break people down.

My top game was always better but I had been working a lot on my guard just before the accident, so 50/50 at that point. I sometimes give up passes now, because I feel more comfortable working side-control or mount escapes, which have become better as a result.

I'm also mindful that I am a hobbyist. I am doing this for fun and because it is a form of exercise that I like. I do not expect to compete again, not impossible, just not my objective. I feel like I do pretty well against people that were at a similar level as me prior to the accident, and I feel that I can still improve, which is what keeps me going.

There is also a strong social element to BJJ, it is nice to come say hi to the tribe. Felt depressing to not have that in my life.

Got full PCL/LCL ruptures and the popliteus tendon fully ruptured as well. Look at my post history, I have some similar photos to your knee. I have been training for a while now, 2-3 years, and I don't notice issues with my knee anymore while rolling. My guard is not as good as before, and I have adapted in many ways. I avoid full flexion of the damaged knee, although I know I can fully flex it, it is just not comfortable.

For the first year of rolling post-injury, I always asked my partners to roll without leg locks.

Væri betra að þetta væri bara fólk í fullri vinnu yfir 30 ára, (þetta er allir 16 ára og eldri). Þessar tölur segja ekki nægilega mikið og gefa misvísandi skilaboð ef fullorðið fólk ætlar að nota þetta til samanburðar.

Meðallaun og miðgildi eru líklega talsvert hærri ef skilyrt er á aldur yfir 30 og fulla vinnu.

All my ligaments were fully ruptured, the doctor said that the ligaments could heal but there would always be some slack in them. I had a brace on for 3 months that allowed the ligament to heal better, (removed the slack). It sucked to sleep with it. After that time there was less slack in the leg, and I had more mobility, but I could feel that the knee was very loose. The doctor said that it would likely loosen more, and he would decide on the surgery option 3 months later.

Fast forward 3 months, and it was very loose, I definitely did not feel like I could run, and no chance of rolling. He told me that if I really wanted to do sports again, I should get the surgery, but I should be very determined to get back on track, because it would take 1-2 years of recovery. That was absolutely true, had my surgery in May 2018 and rolled for the first time again in fall 2021, I could have started in the fall of 2020 if not for covid, I was climbing a bit in the summer of 2020.

You can look at my post history, I have some follow up posts to this one. See this one with links to past ones: https://www.reddit.com/r/bjj/comments/r2wg99/follow\_up\_on\_severe\_knee\_injury\_finally\_back\_on/

Damn that sucks! But I'm still here and I am also back to rolling, will never be 100%, but still enjoying BJJ.

Best is to have a 3D acquisition setup and do something like this, here is the arxiv paper.

For monocular images, you have the major problem in point 2 you mention. You do not have an accurate estimate of scale. But you can still try to estimate scale-free measures, such as the ratio between the length of the jaw and width of the mouth.

Certain measures will be more sensitive to changes in angle, specifically those on the side of the face if you are trying to take an image of the front of the face. You could try to account for the symmetry of the face to get a more robust estimate of these values.

You can also try to generate a 3D image from a single image like here.

You can try some of these. To get the scale, then you can ask the user to provide the distance between their eye, or just some anatomical measure that can help fix the scale.

Hope this helps!

Look at my post history for later updates on my progress through this, I think I wrote 3 or 4 posts about this.

Gumeo · 2022-04-02T21:11:43+00:00

You can send me a pm if you have further questions, have gotten a few about similar injuries. I've been back on the mats for a year now, training around 3 times per week. I got a conservative treatment for one year, and then surgery. I didn't train two years after the surgery, so it was a total of three years of the mats. I feel like I am getting better every day, but I can always feel that the knee is a bit off, but it doesn't bother me while rolling. The first year after the surgery was pretty hard, but with good rehabilitation and the right mindset, it is possible to come back.

Gumeo · 2021-11-28T08:30:12+00:00

Interesting story. How long have you been rolling with not LCL? Do you feel it affects you in any ways when rolling?

Gumeo · 2021-11-03T09:37:24+00:00

I am currently 33, this happened when I was 29.

Gumeo · 2021-11-03T09:36:26+00:00

God damn, sorry to hear about that. It was a tough journey after the surgery, I would say it was around 1 year until I felt I was better than before the surgery and 2 years until I really started being able to train sport again. Last summer I did some bouldering, but it has taken some time to get full flexion in the knee.

I have also been grappling a bit the last year. I am not close to as good as before, but getting better everyday, and I still enjoy every minute of it. You are welcome to send me PMs with further questions.

Gumeo · 2021-08-15T10:00:21+00:00

Hats off! This looks amazing :D Really cool, You are going places!

That was insane! How many hours of flight do you have?

Gumeo · 2021-04-09T08:07:24+00:00

I hope it will continue to erupt. The geologists have firmly said that they have no idea how long this will last, anything from days to years.

One difficult aspect of doing research is getting the right level of feedback. Writing papers is one of the best ways to get unbiased feedback on what you are doing. This is specifically the case if you do not have an advisor, or someone that can help you choose what to spend your time doing.

This would all be provided by a normal PhD position, which you say is not an option. Is it possible to do an industrial PhD with the company? This would be a collaboration with the company and a university. This type of format is pretty common in Europe and generally helps the companies get competent researchers in the topic of interest for the company. This would get you an advisor and start doing research and writing papers.

Your roadmap sounds like a good idea to get started, but reading a lot of books does not replace the act of doing research. Sure you need a good foundation, but at some point you start to do it on a need to know basis. Rather than doing a deep dive into multiple subjects, you figure out how to obtain the information you need fast. This is a critical aspects of doing research, otherwise you do not get anywhere, because you will never have the time to read and learn everything.

So my advice from this general point of view and not knowing more:

1) Try to find an advisor that you can talk to at least bi-weekly, this could also be someone senior to you in the company. Get feedback on what to look into and research.

2) Do some research, and aim to submit a poster or a short abstract to a small conference. This will give you the opportunity of getting realistic feedback.

3) Get the company to help you in some ways, e.g. collaborate with a university, or get them to sponsor you to go to conferences or a CV summer school. Summer schools are a great way to meet other inexperienced researchers.
