#d11 — Public Fediverse posts

Okay, so in the normal eye, there are more L cones than any other. Stim the L cones only, with the L cones making up the majority of the luminance signal (with L cone peak being a greenish yellow).

And meanwhile the S cones are not contributors to the luminance channel (any luminance from the display blue primary is due to the stim of the M and L cones).

The sRGB red primary creates about 21% luminance.

The first image is a neutral grey of 21% luminance #868686 against #f00 .(equal Ys, 0 C vs red 104 C)

The second image is #f00 v #860000 (Lc25)

The third is #009494 vs #f00
(equal Ys — 33 C v 104 C)

The 4th is #d11 v #06f
(equal Ys & equal chroma)

Note: Ys is "screen luminance"

----
Some very rough calcs:

#f00 mostly stims L cone to Ys=21.3%

#868686, the values are
R Ys= 4.5
G Ys=15.3
B Ys= 1.5

So #f00
L 16.6%
M 4.7%
L gets 3.5 x more than M

#868686
R
L cone 3.5%
M gets 1.0%,

G & B
Remaining 16.8%:
L 9.7%
M 8.9%
=
L for the Grey 13.2%
M for the Grey 9.9%

L 1.33 more than M

New #BirdFlu variant found in #DairyCattle. Can #H5N1 be transmitted to humans? [Apparently, the answer is, "YES!"]

According to the the US Department of Agriculture, this is the first ever detection of this bird flu virus variant in dairy cattle.

"The variant of bird flu that killed a Louisiana resident has now been found in dairy cows. Until now, the human cases of bird flu traced to cattle have been mild, mostly #EyeInfections.

"But the U.S. Department of Agriculture confirmed that a strain previously found only in #WildBirds has turned up in dairy herds in #Nevada ‒ raising concerns that future human infections could be more serious.

"Bird flu has triggered a nationwide egg shortage and price hikes in recent months, as infected chickens had to be put to death. It has also coursed through dairy farms in 16 states since last March, according to the USDA, reducing milk production. More than 60 #farmworkers on both dairy and poultry farms have been infected since then, all of whom recovered.

"But one Louisiana resident died last month after contracting bird flu from a backyard flock. That person, who was older and chronically ill, but not otherwise identified, was infected with the D.1.1 variant now seen in the Nevada cows. A Canadian teenager hospitalized with bird flu in November was also infected with D.1.1.

"#D11 is common among the #starlings that migrate through #Nevada in the winter and might have carried the virus into the state, the Nevada Department of Agriculture said in a social media post.

"The USDA said it is working with the state department of agriculture to investigate the Nevada outbreak and limit its spread.

"Until last week, all bird flu in dairy herds had been identified as the B3.13 variant, which was believed to have come from wild birds in late 2023 or early 2024."
