@AngloScot2 @WisdomRebel thesis, and Stu once again lied about it. https://t.co/Uiy8U9BTYp significant evidence in the form of contaminated SRA datasets suggest that the DEFUSE grant have been funded in China, as the full-length HKU4 is not a part of the 2016-2019 grant, but is found before the start
@AngloScot2 @WisdomRebel Date of the 2020-2024 grant of June 2020. The WIV also contained several HKU3-like Coronaviruses, particularly in mice in an 2017 GEO experiment, which is consistent with the published HKU3 and batified mice experiment in the DEFUSE document (evidence from an already conducted
@AngloScot2 @WisdomRebel Experiment). Either DEFUSE or fast-tracked form of the 2020-2024 grant in 2019 would have lead to full-length Sarbecovirus clones being used, leading to SARS-CoV-2 in the lab—they used HKU4 in stead of HKU5 for the MERS spike experiment indicating that backbone sequence distance
@AngloScot2 @WisdomRebel Can not be too high for CoV chimeras, requiring the 4991 backbone or full-length 4991 to be used. In addition, https://t.co/sxm17Eu9hV the 201801-202102 grant of the WIV fits perfectly to DEFUSE since this is consistent with neither the Understanding risk of bat coronavirus
@AngloScot2 @WisdomRebel Emergence grant nor the EID hotspots in southeast asia grant.

@AngloScot2 @WisdomRebel In addition, in contradiction to the Stu’s another claim that 4991 is “sequenced only after 2020”, the full-length sequence of 4991 was already discussed in 2018, and the S protein show significant divergence from RaTG13 when compared against SARS-CoV Urbani. https://t.co/VI7I3PwJoK

@AngloScot2 @WisdomRebel The CGG-CGG pair is at the end point of RNA editing and can not be mutated in the CoV system except for very rare circumstances of RdRp error—it mutates at a rate that is less than 1/10 the rate others can, and no immediately ZAP-beneficial mutation lead to a dS on the CGG pair.
@AngloScot2 @WisdomRebel If you count this low rate of mutation that is possible in the CGG-CGG pair, it is under neutral to slightly positive selection, and not negative or purifying selection. https://t.co/jDy6RoYdSM as for the multi-market hypothesis? Sichuan had loads and loads (1/4 of all sequences)
@AngloScot2 @WisdomRebel That had only T8782C but not C28144T, four of such genomes were found in early Wuhan as well. The 8782/28144 distinction in Wuhan appears in-host before other changes begin to show, so there is no need of two separate introductions for A and B lineage. It happened in humans.
@AngloScot2 @WisdomRebel The FCS PRRARS is highly purified in CaLu-3 cell cultures. Any change to the AA gives significantly reduced infectivity. Therefore, a canonical FCS of RRARR will simply mutate and revert into PRRAR within just 3 passages in the CaLu-3 cell line.

@AngloScot2 @WisdomRebel And “when clear mismatches occur, we will introduce appropriate human-specific cleavage sites and evaluate growth potential in VERO and HAE cultures”.

In deed, CaLu-3 have 1/4 O-linked glycosylation that inhibits cleavage upon P681, saving the heparan sulfate binding peptide without compromising TMPRSS2 usage or immunogenicity. VERO E6 had even more O-linked glycosylation and HS binding as it have even

@AngloScot2 @WisdomRebel In addition to the extremely high stability of PRRA in CaLu-3 and it's lack of stability in-vivo, some of the earliest patients in Wuhan harbored, by digital PCR and nanopore sequencing, large deletions across the QTQTN and SPRRARS https://t.co/YPHooePHko that are specific to

in fact, adaptation in CaLu-3 actually reverses changes that happened in VERO E6. P681 and RRAR is fine-tuned to growth in CaLu-3 cell cultures. P681 guards the cardin-weintraub motif against cleavage in

the FCS is perfectly stable in anything that isn't VERO E6 classic or 293T-ACE2. anything that had TMPRSS2 and grown in trypsin-free media stably maintains the FCS.

https://t.co/NUrJ8AndTx
in fact, the PRRARS, as opposed to other mutated cleavage sites--even the "perfect" H5CS--confers the greatest infectivity in CaLu-3 cells.

https://t.co/TVXC4QOjt0
in fact, even P681R or S686G changes were less fit in CaLu-3 compared to PRRA virus--the P681R virus show either no difference or is slightly less effective compared to the P681 virus, and the S686G virus

Even with VERO E6, only half the time does passage lead to the loss of the FCS—smaller plaques need to be explicitly picked for that to be a certainty.

Marburg virus is a novel virus that escaped from the lab. https://t.co/OGQM6qV27l the only reason why it did not become a pandemic is due to it being too lethal to sustain asymptomatic transmission in humans.

How can we use language supervision to learn better visual representations for robotics?

Introducing Voltron: Language-Driven Representation Learning for Robotics!

Paper: https://t.co/gIsRPtSjKz
Models: https://t.co/NOB3cpATYG
Evaluation: https://t.co/aOzQu95J8z

🧵👇(1 / 12)


Videos of humans performing everyday tasks (Something-Something-v2, Ego4D) offer a rich and diverse resource for learning representations for robotic manipulation.

Yet, an underused part of these datasets are the rich, natural language annotations accompanying each video. (2/12)

The Voltron framework offers a simple way to use language supervision to shape representation learning, building off of prior work in representations for robotics like MVP (
https://t.co/Pb0mk9hb4i) and R3M (https://t.co/o2Fkc3fP0e).

The secret is *balance* (3/12)

Starting with a masked autoencoder over frames from these video clips, make a choice:

1) Condition on language and improve our ability to reconstruct the scene.

2) Generate language given the visual representation and improve our ability to describe what's happening. (4/12)

By trading off *conditioning* and *generation* we show that we can learn 1) better representations than prior methods, and 2) explicitly shape the balance of low and high-level features captured.

Why is the ability to shape this balance important? (5/12)
