Business - France confirms oil crisis, says 30-40 percent of Gulf energy infrastructure destroyed France's Finance Minister Roland Lescure revealed on Wednesday that between 30 and 40 per cent of Gulf refining capacity has been damaged or destroyed by Iran's retaliatory strikes, leaving a shortage...

Acording to france, we are short of 11M barrels of oil daily. considering 434 kg CO2 per barrel, 70% of the year ahead, we have an amount of 1.33 Gt CO2 saved.

only on oil (not counting LNG or demand destructions), we have a 3.5% reduction over last year(37.8 Gt)

I will say this, with not enough knowledge of Automatic Differentiation (AD):

Higher-order implicit differentiation needs to be a part of future AD systems.

Hypothesis: AI writing is bad primarily because in general what makes writing good is the specificity of what it communicates and its information density, so the prompt that produced good AI writing would be as long as the output.

Alternative Fundamental Equation of State for Fluid Carbon Dioxide We present a new fundamental equation of state for fluid carbon dioxide, which is an alternative to the current reference formulation published by Span and Wagn

GitHub - eitsupi/arf: Alternative R Frontend — a modern R console written in Rust Alternative R Frontend — a modern R console written in Rust - eitsupi/arf

Alternate #rlang console in rust. Love the idea - IMHO more programming languages/platforms should embrace modernizing their terminal REPL.

I still consider current #Julialang REPL implementation (maybe with OhMyREPL&Revise) as the gold standard though.

Yeah, unicode for me, ascii for thee

OK, I need to ask, what the hell is this?!

My style guide is:
- all variables should use the Greek alphabet first, then ascii
- for i ∈ eachindex(x) is encouraged over for i in eachindex(x)
- no (ascii) numbers in function names: a₁ is preffered over a1

Robust parameter estimation for rational ordinary differential equations We present a new approach for estimating parameters in rational ODE models from given (measured) time series data. In typical existing approaches, an …

New Symbolic-Numeric algorithm which uses rational polynomial interpolation mixed with differential algebra in order to give a highly robust method for parameter estimation and solving inverse problems on ODEs.

- from Privat et. al, tc-PR is a pretty good EoS with a lot of parameters (for more than 2000 fluids) and predictive schemes if some of those parameters are missing. one surprising fact is that if you use Wilson without a combinatorial term (in a EoS+GE setting), it can predict Liquid-Liquid!

- There are Chebishev coefficients fitted to solve single-component saturation pressures of PR, RK and vdW-type models. Leibovici talked about this, but basically Pr/Tr = f(α/Tr, Ωa). Also known as "Superancillaries", they can solve a saturation problem in a couple hundred nanoseconds.

- CPCA (Cubic + Chain + Association) is a CPA model with a chain term (or a CPC model with an association term?).

- Not really new (2019), but there are new Soave coefficients for PR and SRK:
PR: 0.3919 + 1.4996w - 0.2721w2 + 0.1063w3
SRK: 0.4810+1.5963w-0.2963w2 + 0.1223w3

What's up in the cubic EoS world?

- there are new EoS (Yang-Frotscher-Richter, Almajose-Melida) that try to look up what is the best atractive volume polynomial via exploring the search space (YFR used Symbolic regression, AM used grid search)

I'm not from the USA, but we are also having left primaries in a few days. One entire world of difference between his campaign and the ones here.

If i can summary the differences, I could say that here, every campaign treat you as a child.
