What does a mask do? Blocks respiratory droplets coming from your mouth and throat. Two simple demos: First, I sneezed, sang, talked & coughed toward an agar culture plate with or without a mask. Bacteria colonies show where droplets landed. A mask blocks virtually all of them.

Something you didn't know you needed

Read our last #research on "ADER and DeC: Similarities, Differences and a Unified Framework" with Maria Veiga on Springer Nature at doi.org/10.1007/s10915… Summary: There are many numerical solvers to approximate physical, chemical and biological time dependent problems. 1/5

DeC and ADER are numerical methods widely used in the hyperbolic partial differential equations community. They are arbitrarily high order accurate methods. This means that they can achieve better accuracy with smaller computational cost with respect to low order methods. 2/5

In this work, we find out that the two methods are very similar and that each of them can be rewritten into the framework of the other one. Hence, the DeC convergence theorem can be used also on the ADER method to effectively use the necessary number of iterations. 3/5

Finally, we study their properties as time integration methods, assessing stability, accuracy and ability in dealing with stiff terms in their implicit versions. 4/5

If you are interested in something new with respect to classical Runge-Kutta methods, or if you know one between ADER and DeC, you should definitely check our work. doi.org/10.1007/s10915… 5/5

Glad to share my story in the ⁦The Washington Post⁩ on the travel ban that once made sense. Now it’s only causing hardship. To us, to so many. My story is banal but many are in pain. Time to fix the non-immigrant visa situation, Secretary Antony Blinken⁩ washingtonpost.com/outlook/2021/0…

With inflation at 7.5%, you lose half your money in 9 years. The only way to outperform that consistently, that I have found, is crypto. Just this year I’ve already lost half my money.

Why are most reviews still not double blind?

I'm happy to share the lecture notes my collaborator (François Ged) and I have developed, as an undergraduate mathematical introduction to ML: hanveiga.com/ml_lecture_not…
