Mais le niveau de la mer, c'était censé être la référence, donc 0m ?
Alors pourquoi un #GPS, placé à ~1m au-dessus de la mer, mesure 4m ?

#mer #mesure
1ᵉʳ indice : la #précision de base de mesure du système #GPS est vers ± 2,5m

⚠️ : La #gravité variant (de peu) selon le lieu, les récepteurs couplent la carte des géodésiques de mesure au "Earth Gravity Model 1996", améliorant la précision vers ±0,5m

2ᵉ indice : Le "niveau de la mer" moyen n'est pas LE niveau de la mer
Il y a des vagues, ok, mais pas que, le niveau de la mer varie globalement et localement selon :
- La gravité (encore)
- Sa température
- La pression atmosphérique
- La lune (marées)

What are the #histopathology image #WSI patterns associated with gene expression in cancer? Can we discover them with #AI and use them for spatial profiling and #precision medicine?
Our preprint explores limitations & possibilities of #cpath for this.
biorxiv.org/content/10.110… Image
Existing methods aim to predict expression of individual genes from #WSIs but ignore any inter-dependencies in expression across genes. We show that it is typically not possible to predict expression of a single gene due to such codependencies as shown in fig for a group of genes ImageImage
To formalize this, we first used mutual information to identify groups of genes whose expression in breast cancer patients are significantly inter-dependent and form the basis of important cancer and biological pathways and can be used for precision medicine. ImageImage

How precise are noisy #morphogen gradients in #tissue #patterning?

It turns out that the positional information they convey to #cells in the #neuraltube is much more accurate than previously estimated!

Our new #devbio paper is out in @NatureComms: rdcu.be/cH8Fx Image
A methodological subtlety has previously led to overestimated positional errors of the morphogen gradients in the mouse neural tube. We reanalysed the noisy gradients and found that the positional information they can convey to cells is actually orders of magnitude more precise. Image
Also, morphogen gradients in differently sized tissues must not be pooled and rescaled to their mean length, or else an artificial positional error is added. Image

#Tablazo Una jueza de Anzoátegui otorgó una medida de arresto domiciliario a la señora Carmen Gamboa Salazar, esposa y presunta cómplice del narcotraficante Eustacio Cirilo Córdova, "el negro Cirilo", quién estuvo fugitivo 12 años tras ser condenado por la justicia de #Francia. Image
De acuerdo con una fuente jurisdiccional, el tribunal (presumible el 2° de Control) en la audiencia preliminar admitió parcialmente la acusación por tráfico de armas y desestimó asociación p/ delinquir. Mantuvo detención a Córdova pero dió casaxcarcel sin custodia a la imputada.
Ante la decisión judicial el @MinPublicoven ejerció la apelación con efecto de suspensión de la medida de arresto domiciliario, pero el recurso no fue tramitado.
Por lo que la imputada quedó en la práctica en libertad y se le considera fugitiva. Ahora procuran su recaptura.

Immensely proud of bring of bringing some important aspects of #precision #proteomics to @NatureRevGenet with @ksuhre @markmccarthyoxf covering #gwas #pqtls and more nature.com/articles/s4157… @scilifelab @KTHresearch @ProteinAtlas
We provide insights into procedures, challenges, considerations and opportunities when combing #genetics and #proteomics for more informed, large scale studies of the circulating #proteome . #biobanks #olink #somalogic #massspec #affinityproteomics #epitopes #causality
Am very grateful to @ksuhre and @markmccarthyoxf for joining in on this journey and making this a wonderful experience over three continents, timezones, project and travel schedules!

Dear #GeneTherapy twitter, thank you for your had work enabling cures for diseases of #Aging. What's that, you aren't working on that at all? Oh but you are, and @Nicole_Paulk and I wrote an oped to explain why: cellandgene.com/doc/why-comple…
#Aging is a set of biological mechanisms that cause all your tissues to decline in distinct ways, and in doing so lose physiological coherence. This process is the main risk factor for most US deaths (incl. #COVID19).
The systemic nature of #Aging means that old patients are usually #Comorbid, suffering from more than one disease. Our best remedy right now is often a cocktail of drugs, whose side effects interfere with each other and further strain other organs.

Error, incertidumbre, precisión, tolerancia y exactitud. Términos relacionados con la calidad en una medida o la calidad de un dato espacial geográfico. Pero, se conoce con claridad qué significa cada término?. Ven conmigo 🤙
Comenzaremos con el término ERROR, es la diferencia entre el valor medido de una magnitud y el valor considerado como valor real o de referencia. El error no es conocido. #error
INCERTIDUMBRE: parámetro que nos indica la dispersión de los valores atribuidos a una magnitud. Este parámetro es conocido. #incertidumbre (Este es mi día a día cuando me pregunta el camarero qué quiero de beber... y ante la incertidumbre...al final acabo pidiendo agua)
