Day 332: Solid modeling course day 2

Printer

Yep, still dealing with printing issues so I have the dual extruder on. Ugh!!!!!! 5 HOURS still left on this print. Why does 3D printing have to be so sloooooooow?!

Well yesterday was day 2 of my solid modeling course, today is my last day of the class. Unfortunately tomorrow is my 3D printing course and I still haven’t got my printer well behaved yet. I guess we get to see all the 3D printing troubles! In any case, let’s talk about how the class went yesterday and what I have planned for today.

Day 331: Solid modeling course day 1

20200715_134927

The dual extruder attachment, the current bane of my existence!

Well can’t complain too much about the first course. I’m used to people talking to me so it was an odd feeling talking into a screen with no one talking back. I had a few questions, but mostly the course was on how to think about solid modeling, so maybe not a lot of room for questions?

Day 330: I’m teaching this week!

Harbinger

I love mass effect, so I really thought this was a perfect header image for the post since I am… assuming control!

Well I mentioned it a few days ago, but it’s day one of four today. I’m teaching three courses on solid modeling and one on 3D printing * Shakes fist at 3D printer who keeps giving me problems * and I figure I can talk about how my classes go after the fact, but let’s talk about my prep for these classes so my students get the most out of what I have to teach them.

Day 329: More 3D printing issues!

Cat boss

My boss is not happy with the work I’m doing, you can tell since she didn’t want to look at me when I took this photo.

I’m giving a class on 3D printing this week and of course my printer decides it wants to throw a fit. So my print had to be stopped (18 hours in) and the printer needed a good talking to. It’s not the printers fault, maintenance happens, so let’s talk more about my poor FDM printer (Acronym defined yesterday).

Day 328: 3D printing… ugh

3D printing

Well it’s time, in a few short days I’ll be doing a marathon session of courses for the summer interns. I admit it I bit off a lot! I’m doing three solid modeling courses, so the basics, plus a 3D printing class. Today we’re talking 3D printing because, well it’s a headache even though the prints themselves can be worth the pain. I know if I can pull off printing what I’m working on now it will be worth it… I hope.

Day 327: Solid Modeling – Week 5

Light bulb render

Okay everyone, I had a bright idea for our sphere… get it, get it!?!

Wow, week five already! As per my usual intro, this is a free class using FREE software so if you ever wanted to create a 3D model, this is for you and all you need is internet access to use the program we will be using. Now if you are just joining you’re going to want to start at week one, which you can find all the posts in the super lovely Solid Modeling for Beginners category. We finally did it, last week we made something cool looking! Today we’re going to expand on that and use what we learned to create another awesome thing!

Day 326: Review: The state of spinal cord research

Figure 2 from and yet it moves
Figure 2 from and yet it moves

Facilitation of stepping-like volitional oscillations using non-invasive transcutaneous electrical spinal cord stimulation in SCI subject. (A) Position of the participant in the gravity-neutral apparatus. (B) Biphasic electrical stimulation was delivered using unique waveforms consisting of 0.3–1.0 ms bursts filled by 10 kHz frequency that were administered at 5–40 Hz. (C) EMG activity of right soleus (RSol), right tibialis anterior (RTA), right medial gastrocnemius (RMG), right hamstrings (RHam), right vastus lateralis (RVL), right rectus femoris (RRF) and angular displacement in the knee and hip joints of both legs during leg oscillations with a voluntary effort alone (Vol), stimulation at T11 (Stim), and Vol + Stim are shown. (D) Schematics demonstrating the approximate location of transcutaneous electrodes above the lumbosacral enlargement, in relation to the location of the motor pools based on Kendall et al. (1993) and Sharrard (1964).

Well it’s been two weeks (roughly) and my PI asked specifically that this week I do a review on the state of spinal cord research, with emphasis on the spinal cord stimulation work I’m doing. So this review is going to look slightly different, namely it has a rather long references section (15 total). If you find this research fascinating I recommend “And yet it moves” (reference 5). It’s long, but open access and worth the read. I’m a little bias though, my Co-PI is one of the authors. In any case, I had two weeks to write this, so hopefully it is a good dip into what we know about the spinal cord and a lot of what we don’t. Enjoy!

Day 325: Religious freedom and you

Bill-of-Rights

I’m not here to tell you how to live your life. Then again, that’s the point of the post. The United States was founded on the idea that we can believe, or not believe, whatever we want and the government would not do anything to impose one religion on people above any other. We’ve failed miserably, but that was decades in the making.

Day 324: Rewriting

edits

Today is a bunch of meetings and a bunch of editing. As I mentioned (or at least think I mentioned here), I had to meet with the senior author for the paper I’m working on and I got a lot of feedback, some of it was good, most of it meant more work for me. That’s the process though, write, rewrite, re-re-re-re…rewrite.

Day 323: Skype a Scientist!

wiring

Today is going to be fun, I’ve got a ton of meetings, but I also get to do outreach. If you’re a scientist, you can do it too, no matter where you are in the field, sign up at Skype a Scientist. While I wanted to write this post before my sessions I ended up having to write it afterwards so let’s get into what I talk about and how it went.

Day 322: Stuck

hamster wheel

Ever feel like you’re just going around in circles like a hamster in a wheel? I’ve been working on about a million different things and I just can’t seem to get them off my plate. The work just keeps going and it’s got me somewhat down. Maybe I just need a day off or something.

Day 321:Wear the damn mask

Daily Life In Belgium Amid Coronavirus Outbreak

Today is just a simple plea to my readers. Wear the damn mask. It’s not that hard. When you go out you put on your clothes, you can put on a mask too. Since people seem to be making this a political statement now, I guess I can explain why it’s not one.

Day 320: Solid Modeling – Week 4

Finished Rocket

We’re making something a little more exciting than a cube today. Yay!

Welcome to week four! For those of us just tuning in, this is a class for solid modeling using FREE software, so if you have internet access, you can do this too! You can find the whole course in the handy Solid Modeling for Beginners category. Last week we introduced a whole lot of navigation tools and helped you get situated into the world that you’ll be able to model in. So let’s get started by doing a quick recap of the past weeks and hopefully you’ve done your homework because we’re using that part today to make something more impressive than a cube.

Day 319: The (dis)information age

misinformation

Look around, we’re drowning in information. It’s an overload, we literally were not made to absorb this much information all at once. News stories bombard us with new bits of it. Social media is full of it. Ads promise you forbidden knowledge with this one weird trick. It’s no surprise it’s hard to tell what’s real.

Day 318: The why.

parts

With everything going on it’s been tough to write about just one topic. When I started 365 days, I started it with the intention of highlighting my struggles and trials through one full year of my PhD with the idea that I may (or may not) keep going for the duration of my PhD process. Then COVID hit, Black lives matter protests took off (finally), and I had the realization that I, like most people, am more than just my studies.

Day 317: Mental health and you

neural symphony

I scream it loudly from the mountain tops, I suffer all the fucking time from mental health issues. I do it because staying silent doesn’t keep me from feeling them and it does nothing for others who are suffering. Yes, it’s embarrassing to talk about it because it feels like a taboo, or something you’re making up, but that’s why we need to talk about it and why you need to keep track of your own mental health.

Day 316: Internships in the pandemic

Distance learning

For those of you not in academia, summertime means we get interns in the lab to learn about how research works in a real-life setting. We typically have them help with things that require basic skills, but lets them see how research really happens. This year, we are doing everything virtually thanks to COVID-19. This is a great thing because it really means we’re doing what we can to stop the spread while still giving students a chance to experience research.

Day 315: Neural Engineering in a pandemic

pandemic PPE

For the past week or so my PI has been away, so I’ve had the chance to work on other projects from home. Unfortunately he returns this week so I’ve got to switch gears from protests, working from home, and undergrad mentoring back to experiments and experimental setup. As the senior student in the lab, I’ve got a lot of responsibilities.

Day 314: It’s all part of the act…

Ringleader

Step right up boys and girls! Hurry, hurry to the greatest performance you’ll ever see… Who doesn’t love a good show, right? I mean you get to escape reality for a moment, forget your troubles, and see a whole different world. Unfortunately, once the show is over, it’s business as usual and that can’t happen, not this time. So why are the people in charge doing the same song and dance?

Day 313: Solid Modeling – Week 3

 

Sketchup planes

This course will all be taught using free software so have no fear, you can do it too! For those just joining us you can find all the posts in this series in the handy Solid modeling for beginners category. For the past two weeks I’ve been going over best practices. The reason is the tools are straightforward to learn, but how we use them is what separates someone who is learning from someone who is a pro. I have had some thoughts about what I wanted to cover this week for that reason, but this week we’re making something and by me we, I mean you! First, let’s do a quick recap of what we’ve learned and we can get started.

Day 312: Yes, the protests are still going…

George floyd

It still appears there is a media blackout on the protests (first mentioned in my other post). That doesn’t mean we’ve stopped though! It also unfortunately doesn’t mean the police have stopped. In fact we’re seeing some really… umm scary tactics being used by the police to * checks notes * beat us until we stop protesting police violence.

Day 311: When voting isn’t enough

Gerrymander

Rawr! Beware, the Gerry-mander!

I’ve been debating about writing this post and it’s just been rattling around in my head for the past month or so. Voting can change the course of history, frankly we saw that in the 2016 elections, but we also saw something else. Your vote doesn’t matter and that isn’t by accident. But wait, I just said voting can change the course of history, so how does it not matter? Well for that we need to go back, way back.

Spatiotemporal spinal maps of ipsilateral a-MNs. (A) Experimental set-up for ankle plantar flexion. (B) HD-EMG is decomposed into a-MN spike trains using a convolutive blind-source separation technique. (C) The spinal output to generate the neural drive to muscles is estimated from the a-MN spike trains.

The world is on fire, we’re protesting for a future, but today I have my review paper due so instead of writing about my frustrations I’m going to share my review. Today we’re looking at the effects of trans-spinal direct current stimulation (tsDCS) on alpha motor neurons and how we can determine that effect using electromyography. It’s actually a very cool paper, the work is well done, and it’s open source so you can read it if you’re interested.

Day 309: No tests, no worries

head in sand

If I ignore my bills, I would have very few, if any. If that logic seems, well wrong, then I’m not surprised. Ignoring something doesn’t make it magically go away. Yet, Trump has touted, yet again, that if we slowed or stopped testing, we would have very few, if any cases of COVID19. I mean, with that kind of logic, you could have no more bills with this one weird trick!
