re: your last point that is not true. we can measure arbitrarially quickly (Nottingham group does some 3d EVI at ~100ms TRs). You can also reduce volumes and just look at single slices etc, a lot of the fundamental research did this (wash U

Unfortunately, for experts in the field, this is a "we know" article that probably shouldn't have been published, and belongs more in a textbook...

agree. especially the comments saying "just address it". Its a lot of technically complicated interactions between the physics, imaging parameters, and processing techniques. Unfortunately the end users (typically neuroscience&#

it doesn't measure the oxygen level directly either. the bold signal is correlated to dephasing induced by the oxy/deoxy hg ratio that isn't even necessarially localized to the voxel (flow or long range magnetic susceptibilit

+1 F# is criminally under-used

honestly this sounds like you've never really done it. FP is much better for ergonomics, developer productivity, correctness. All the important things when writing code.

by physPop 1y ago
exactly. people delude themselves thinking this is productivity. Tweaking prompts is to get it "right" is very wasteful.

it really doesn't take that long. Maybe if you're super junior and never coded before? In that case I'm glad its helping you get into the field. Also, if its taking you months there are whole new models that will get released

Because over the course of a billion years of history, evolutionary pressures essentially end after child-rearing ages.

clippy is kind of taken (a very popular rust linter). Suggest considering a new name to differentiate yourself!

Safari is also not adblocker friendly. Lots of other entrants to try though. Brave in particular is great!

Yes because injecting nowFn is trivial and not a case for DI. Consider a database handle, or network socket, or http response payload. Clearly each class shouldn't be making its own version of those.

I disagree -- the funding isn't ROI based at all. Heck NIH doesn't even really audit how well the funds were spent, how could they? They don't even really assess if the research had impact, save for counting journal articles

This isn't law, its journalism, and frankly the article is well written and asks a good question -- why are these (extremely wealthy) universities finances so brittle?

Its because we don’t normally inject Gad in CSF. Its kind of wild west to even do so, and these researchers were able to identify this unique dataset and ask some interesting questions.
47.
by physPop 2y ago
Unfortunately no, that is not how the contrast agent gets around. Most Gd agents are huge and don’t leak out of the vasculature unless there is a disruption (tumour etc).

I work in this field —- You’re mis-construing the research a bit. Your reference talks about CSF flow on a more macroscopic scale (clearance out the fourth ventricle), which is fundamentally different than the glymphatic system referenced i

I would just like to point out the irony of claiming that people live in a way inconsistent with scientific rigour, based solely on personal experience.

This is called super resolution (SR). 2x SR is pretty safe and easy (so every pixel in becomes 2x2 out, in your example 800x600->1600x1200). Higher scalings are a lot harder and prone to hallucination, weird texturing, etc.

Outsider to the field and just curious: Does anyone know how these kinds of processors compare to the custom silicon by aws/google/tesla?

The site is a little misleading, saying "Several of these devices even led to patient injuries including bleeding, organ puncture, and even cobalt poisoning." The majority of documentation in the 510k process is to mitigate harms

This looks nice. But glaring issue I have is documentation: Don't make people have to pull run code to get at the documentation. Host it somewhere on your website or readthedocs.

Then they shouldn't be C-level execs. We should expect more proficiency from people we pay so highly.

I'm not sure how many of those are valid any more.
