In case anyone's keeping score, the idea that JFETs have hugely variable properties and that this problem cannot be - or at least has not been - fixed with different design or manufacturing practices, this batch showed it pretty clearly to me.
20 J113s, minus 1 fake, equals 19 devices. I measured the Vgs / pinch-off voltage and the Id / drain current in my test rig. The result?
6 very distinct bins with between 2 and 6 devices in each. Vgs overall varied from (-) 1.30 V to 2.11 V (variance is 38% of the larger value, or 62% of the smaller...), and Id from 5.7 mA to 12.8 mA, a spread of 125% (!) of the smaller value.
No wonder so many JFET circuits just don't work if you don't hand-match the devices.

“#Gayface” is a #real thing, according to this new #study
It’s about sym 👏 met 👏 try 👏, honeyyy…
While #descriptors such as “#gayface” and “#gayvoice” can be used in a #derogatory #manner, it turns out that #homophobes aren’t very good at #spotting #queer #characteristics.

[Correspondence] Virological #characteristics of the #SARS-CoV-2 #KP311 #variant https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(24)00505-X/fulltext?rss=yes
SARS-CoV-2 #JN1 variant (#BA28611), arising from BA.2.86.1 with spike protein (S) substitution S:L455S, outcompeted previously predominant #XBB lineages by beginning of 2024. Subsequently, JN.1 subvariants including #KP2 (JN.1.11.1.2) & #KP3 (JN.1.11.1.3), which acquired additional S substitutions (eg, S:R346T, S:F456L, and S:Q493E) have emerged concurrently (appendix pp 19–20).2

KP.3.1.1 exhibited a higher Re, higher pseudovirus infectivity, & higher neutralization #evasion than KP.3. These results align with our recent report that #JN1 subvariants with S:S31del (eg KP.2.3 & LB.1) exhibited enhanced Re and immune evasion compared to other JN.1 subvariants without S:S31del (eg JN.1, KP.2, & KP.3), highlighting evolutionary significance of S:S31del in JN.1 lineages.

#SimonHarris will not #abandon #hatecrime #bill.
The #CriminalJustice (#Incitement to #Violence or #Hatred and #HateOffences) #Bill 2022 would amend the #law in relation to the “#prohibition of #incitement to #violence or #hatred against a #person or a #group of #persons on account of certain #characteristics”.

The phrases 'identify' or 'identify as' wrongly imply that a deliberate choice was made by LGBTQ people to become LGBTQ.
#SexualOrientation and our #Gender (#GenderIdentity) are #innate #characteristics, not #choices.
It's time to move past this #HarmfulLanguage!
We are who we say we are, and deserve to be #respected and #affirmed for having the #courage to be our #TrueSelves."

The #policy as it stands #protects #transgender #students and others from #targeted #harassment based on their #innate #characteristics, which would include #deliberate #misgendering in the case of #trans #people.
Judge Marbley ultimately #disagreed, #concluding that the #USConstitution does not contain a #right to #misgender and #bully #trans #students.
