The Grand Deception #372,472,121: Trump signs USELESS executive order NOW, in 2025, directing Dept of Education and Health & Human Services to create “ a plan” to end vaccine mandates for Covid. Why is this deception? 1) Trump knows it’s useless since his order will have little national impact because Covid vaxx mandates have ALREADY been dropped at most schools and colleges across the US 2) Many states have ALREADY passed legislation forbidding such mandates, because of the mass bottoms up protests resulting from TruthFreedomHealth.com’s relentless leadership & education. 3) During COVID, Trump claimed he was powerless to end vaccine mandates as it was a “State issue;” but, now he has mysterious powers to do it?! BULLSHIT. 4) This bogus order is being issued now so Trump can steal the victory of TruthFreedomHealth.com - the people - who stopped vaccine mandates at the local level, bottoms up. This order gives all of you an opportunity to see how Elon Trump, Inc. deceives us. There is one goal alone ShatterTheSwarm.com! -Dr.SHIVA

Foundation Model Enables Interpretable Open and Error-Tolerant Searching for Mass Spectrometry-Based Proteomics 1. This study introduces yHydra, a foundation model leveraging dual embeddings for mass spectrometry and peptide data, enabling efficient and interpretable open and error-tolerant proteomics searches in Euclidean space. 2. A major breakthrough of yHydra is its ability to identify proteoforms and post-translational modifications (PTMs) through open searches, which assign delta masses to peptide identifications, achieving up to a 25% increase in protein identifications at constant FDR compared to state-of-the-art methods. 3. yHydra’s joint embeddings allow for a unified analysis framework, facilitating fast open searches that process tens of thousands of spectra against millions of peptides within seconds using GPU-accelerated k-NN search algorithms. 4. The model's error-tolerant search employs gradient descent in the embedding space to decode novel peptides arising from mutations, splicing, or PTMs, boosting peptide identifications in challenging datasets like monoclonal antibodies and cross-species proteomes. 5. Extensive evaluations demonstrate yHydra’s superiority in peptide-spectrum matching (PSM), with better target-decoy separation and enriched identification of PTMs like oxidation and carbamidomethylation compared to conventional tools like MSFragger. 6. yHydra’s embeddings are biologically meaningful, as shown by UMAP visualizations correlating charge, precursor mass, and PTMs, enabling researchers to explore peptide neighborhoods and infer modification patterns. 7. The study highlights yHydra’s flexibility as a standalone tool or in synergy with existing engines, offering scalable solutions for MS-based proteomics, proteogenomics, and de novo peptide sequencing. 8. yHydra is trained on nearly 20 million PSMs from 67 repositories, ensuring robust generalizability across proteomics datasets and enabling future extensions like multi-omics integration and six-frame translation. @w_zalm @AltenburgTom 💻Code: gitlab.com/dacs-hpi/yHydra 📜Paper: biorxiv.org/content/10.110… #Proteomics #MachineLearning #MassSpectrometry #Bioinformatics #DeepLearning

Here’s the scientific paper Bhattacharya co-authored PROMOTING lockdowns, social distance, vaccine & mask mandates, while I was fighting them I’m starting in JAN - MAR 2020. The “Great Barrington Declaration” in late 2020 was a Limited Hangout. Video coming.

While I an expert on the immune system, as early as JAN 2020 shared REAL SCIENCE to STOP LOCKDOWNS & exposed BS of Masks, etc Scumbag MD Jay Bhattacharya, Et Al at CIA HQ a.k.a. “STANFORD” put out PRO-VAXX, PRO-LOCKDOWN, PRO-MASK “science” NOW, HE’s a “hero”?! The proof (8/20)

Coca-Cola is in $50 billion of debt. Budweiser is in $78 billion of debt. Target is in $12 billion of debt. These corporations don’t push woke nonsense by accident. They are completely leveraged by firms like Blackrock. Shout out to @va_shiva for coming up with the term #SystemsThinking

This is Nicola's transformation, overcoming her severe overbite naturally. When she was 12 she was told that her overjet could only be fixed by jaw surgery. She thought this was the only option. Until she found out about my father, Professor John Mew...🧵

BREAKING: Do you want to formally complain about the atrocious police misbehavior in the failed Karen Read frame up? Below is a link to the MA POST Commission form for submitting a formal complaint about the bent cops in the Karen Read case. The POST Commission is mandated to determine what misconduct should result in decertification of corrupt cops as "peace officers."
