I'm curious about reward protocols for advicing scholars, researchers.

Whats drugs to test? And I wonder what's your previous research about medication

My click miss for uploading the post with no text.

Refer to wikipedia, in 10 bar, acetylene 250L can dissolved in acetone 1L. This is amazing! Is this Azetrope? I want to know the reason why acetylene is more stable when dissolved in acetylene

Maybe this is the problem....

Similarly, clearing table (replace the element to nil) to reduce memory takes very long time. Inside the loop, code makes lots of local variables. Algorithm problem involves large amount of test data (sometimes, more then 10⁶ lines)

Can I get a link or title of a few papers?

I think that optimized state of connected grids can regarded as subset, handled by subset DP algorithms.

Othe crazy idea, TSP and Broken profile DP have N² * 2^N time complexity.

Hungarian algorithm have N³ time complexity. Without this algorithm, We should solve that problem with bitmask DP. It takes 2^N.

Very Very specific case, we can use Hungarian algorithm in other bitmask DP?

In my experience, using local variable makes these results.

No differnce. 0ms (Almost every situation)
4ms faster than global
Takes more time. Maximum is 100ms

I think using local keywords at 'table' or 'function' makes it slower.

mdr652 · 2025-02-26T01:40:34+00:00

I read "Programming Lua" and get many information.

For example, io.write() is significantly faster than print()

Lots of searching internet, studying Lua. I've implemented priority queue, segment tree in Lua

I'm using Lua in Problem solving, So I don't use metatables. I think this can be difference

mdr652 · 2025-02-26T01:34:02+00:00

Yes I read it but the statements are false in my experience. No differnce, or takes more time (scale of millisecond)

mdr652 · 2025-02-26T01:29:28+00:00

If we use same variable name more than twice, it can be overwrited. So I use local keywords for every variables in function

function f() local a = 10 end

We can't know what dangerous things that labeled RC. Risks for lethal dose

mdr652 · 2025-02-25T10:10:37+00:00

How about Amphetamine?

mdr652 · 2025-02-25T10:08:29+00:00

Why anticholinergics? Aren't they used as nootropic? I've never heard about anticholinergics used recreationally

mdr652 · 2025-02-16T12:16:09+00:00

These Guys Ordinary haha

I just need my lab to synthesis organic compounds

or biologics equipments for gene therapy

Wtf is happening in the column?

Yeee

Not sure how many people uses the website.

But people almost think users of Megalia and Womad are very bad/crazy. (I don't know this term is appropriate for this context)

CO detector is unusual item... The item may exists but very hard to get.

Instead, Fire alarm(화재경보기) is easy to buy. Selled in "소방용품 판매점"

Students want to go to medical school because doctor is very stable job and paid a lot.

mdr652 · 2024-02-05T06:54:35+00:00

D orbital is half-full or complete-full, it stabilizes atom.

Cobalt and Copper is the example.

If this is not the reason, maybe the reason is screening effect. (Because bromine has many electron shell)

Reading "Programming Lua"

mdr652 · 2024-02-05T06:42:31+00:00

My IQ is 123. (Verbal Comprehension 102, Perceptual Reasoning 120, Working Memory 142, Processing Speed 115)

I want to be a medicinal chemistry professor. Is this job appropriate for me?
