Read—in French—The Grave of the Fireflies (火垂るの墓), written by Nosaka Akiyuki in 1967, and which inspired the eponimous Ghibli Studio anime by Takahata. A very vivid reporting on the slow deaths of the young narrator and of his sister, in the final days of WW II that left them to try to cope by themselves from the lack of food. I was quite surprised by the style, raw and oral, with hardly any punctuation, that reminded me of the early Céline. The book contained a second short story, Amerika Hijiki (or American weeds), also related to the WW II trauma suffered by the author. Recommended, if not for young readers. I also read The Wrong Unit, by Rob Dircks, a science-fiction novel set in the 2800’s, which follows a humanoïd robot caring after a child with a particular destiny. Not as fun as Murderbot, and not particularly deep in its human-AI-robot relationship, even less in its scenario and its creation of a 2800’s environment where everything sounds 2020’s, except for teleportation (!), but definitely readable.

Just as during my previous, private, visit to Venezia, I cooked there a large dish of (spinach) gnoccheti with anchovies that lasted the week, plus had the possibly best-ever squid dish I ever tasted at Da’a Marisa. Where else?!

Watched Jo Nesbo‘s Harry Hole’s Devil Star series on Netflix. With mixed feelings. On the one hand, the rendering of a gritty, harsh, unromantic, fantastic, Olso and of a unequal, corrupted, crumbling, society far from the usual postcards is riveting. With the actor playing Harry Hole fitting the role brilliantly. (Maybe not the most adequate adjective for an alcoholic, Camels chain smoking, (hyper)violent, insubordinated, police officer!) On the other hand, the scenario is very weak and with too many red herrings and convenient coïncidences and global conspiracies. Given the last scene, there may be another season in the near future…

Likelihood-free Posterior Density Learning for Uncertainty Quantification in Inference Problems
Generative models and those with computationally intractable likelihoods are widely used to describe complex systems in the natural sciences, social sciences, and engineering. Fitting these models to data requires likelihood-free inference methods that explore the parameter space without explicit likelihood evaluations, relying instead on sequential simulation, which comes at the cost of computational efficiency and extensive tuning. We develop an alternative framework called kernel-adaptive synthetic posterior estimation (KASPE) that uses deep learning to directly reconstruct the mapping between the observed data and a finite-dimensional parametric representation of the posterior distribution, trained on a large number of simulated datasets. We provide theoretical justification for KASPE and a formal connection to the likelihood-based approach of expectation propagation. Simulation experiments demonstrate KASPE’s flexibility and performance relative to existing likelihood-free methods including approximate Bayesian computation in challenging inferential settings involving posteriors with heavy tails, multiple local modes, and over the parameters of a nonlinear dynamical system.

In this issue of Nature, uncovering the fundamental (and Ig-Nobel worth) reason why basketball shoes are squeaking, the reason being a shockwave travelling through the sole!, two tribunes against nuclear testing and “must & should” towards a successor to the START treaty… While we should ask & act for a global and if not unilateral nuclear disarmament! This alas coïncides with France announcing the increase of its nuclear arsenal and the extension of its “umbrella” to several EU countries…

And another coverage of the deplorable Trump administration dismantling the biodefense and pandemic preparedness branches of the US NIAID, presumably a late under-the-belt jab at the national institute Anthony Fauci directed for 38 years. Meaning one of the forefronts for pandemic research and vaccine development has been dismantled. Plus the US EPA revoking the 2009 statement that climate change is endangering the US population and removing greenhouse-gas emission rules. In tune with the Drill, baby, drill! motto of the Trump supporters more interested in their short-term profits than in the long-term (no-)future of the country. Paradoxically sitting in the same issue as a comment calling for a policy-making assessment of avoidable climate-change risks. Illustrated by London’s drownin’ below

And a summary of their conclusions from 23 of the 27 members (from 27 countries) of the Scientific Advisory Group for the Origin of Novel Pathogens for the WHO. After 3.5 years of debate on the origin of COVID-19! Four hypotheses are examined and other hoaxes and conspiracies are debunked.

Another political entry about the EU and its Horizon Europe programme (that is funding my ERC Synergy grant) baring (researchers from) Chinese research organisations from applying for its grants in sensitive methodologies, in order to prevent “the undesired transfer of IP”. Following similar and earlier actions in the US with the (newspeak!) China Initiative launched by Trump 1.0 that turned into a witch hunt.

Read Braking Day, an archi-classic space opera of a spaceship travelling for generations to a substitute planet. With the archi-classic reproduction of earthy behaviours and habits (how on,,, Earth!, one could imagine smoking being allowed on a spaceship? commercial goodies on sale when approaching destination? shopping malls?) Archi-classic heroes as well, standing just on the wrong side of the rules as a shipbound form of smuggling… The no-so-classic is a class A spoiler that emerges half of the book, non-too-soon, and turns the charactera and then some into actual heroes. Very very light and not recommended!

In-between two weeks in Venice, I cooked a veg curry with (old) butternut, leeks, (new) onions and a yellow species of beetroot I had never seen before, Eaten with my freshly made kimlchi that was somewhat too fresh. The second pot is still burping! And had the worst ramen dish in my culinary experience, in Strasbourg, obviously not the centre of the ramen universe!, where half the ingredients were freezer cold (and the other half just marginaly warmer). (But tasted a new and nice category of curly pasta while in Venice (2), the week before, the Napolitean riccioli!) Also cooked a second sweet potato and cocoa cake for Venice (3), which led to a lengthy security check at the CDG airport!

Watched Undercover Miss Hong, a Korean drama set in the 1990’s, with vintage computers, clothes, and (just emerging) mobilephones. Beyond that plunge in the past… The scenario is paper-thin and is spread over too many episodes, with a soapy ending, but the duo of (female) central characters is enticing (if not for their borderline ethics). The series’ soundtrack is original, if not particularly striking. Slightly funny but not particularly recommended!
