Chow-Witt Rings of Classifying Spaces of Products of Multiplicative and Cyclic Groups
We compute the total Chow-Witt rings of the classifying space Bμ_n of the roots of unity, as well as the products BG_m x Bμ_n and Bμ_m x Bμ_n for all m,n greater than or equal to 1 based on the strategy by di Lorenzo and Mantovani (2023) for Bμ_n with n even. Moreover we compute the total I^j-cohomology and Chow-Witt rings of P^q x P^r for all q,r greater than or equal to 1 and of BG_m x BG_m.

... We know from brain research that institutionally reared children have
enlarged, overly active amygdalas---an area of the brain involved in
emotional processing ---especially pay excessive attention to negative
information.  They are easily frightened.  Their emotion regulation
and mental health are permanently damaged, which is why the Romanian
orphanages were known as the "slaughterhouses of souls."
There are many parallels with animals reared in…

But there is no certainty that madness was content to sit locked up in its immutable identity, waiting for psychiatry to perfect its art, before it emerged blinking from the shadows into the blinding light of truth. Nor is it clear that confinement was above all, or even implicitly, a series of measures put in place to deal with madness. It is not even certain that in this repetition of the ancient gesture of segregation at the threshold of the classical age, the modern world was aiming to wipe out all those who, either as a species apart or a spontaneous mutation, appeared as 'asocial'. The fact that the internees of the eighteenth century bear a resemblance to our modern vision of the asocial is undeniable, but it is above all a question of results, as the character of the marginal was produced by the gesture of segregation itself. For the day came when this man, banished in the same exile all over Europe in the mid-seventeenth century, suddenly became an outsider, expelled by a society to whose norms he could not be seen to conform; and for our own intellectual comfort, he then became a candidate for prisons, asylums and punishment. In reality, this character is merely the result of superimposed grids of exclusion.
The gesture that proscribed was as abrupt as the one that had isolated the lepers, and in both cases, the meaning of the gesture should not be mistaken for its effect. Lepers were not excluded to prevent contagion, any more than in 1657, 1 per cent of the population of Paris was confined merely to deliver the city from the 'asocial'. The gesture had a different dimension: it did not isolate strangers who had previously remained invisible, who until then had been ignored by force of habit. It altered the familiar cityscape by giving them new faces, strange, bizarre silhouettes that nobody recognised. Strangers were found in places where their presence had never previously been suspected: the process punctured the fabric of society, and undid the familiar. Through this gesture, something inside man was placed outside of himself, and pushed over the edge of our horizon. It is the gesture of confinement, in short, which created alienation.

Inside Knowledge: Graph-based Path Generation with Explainable Data Augmentation and Curriculum Learning for Visual Indoor Navigation
Indoor navigation is a difficult task, as it generally comes with poor GPS access, forcing solutions to rely on other sources of information. While significant progress continues to be made in this area, deployment to production applications is still lacking, given the complexity and additional requirements of current solutions. Here, we introduce an efficient, real-time and easily deployable deep learning approach, based on visual input only, that can predict the direction towards a target fro…

Good word, a little tricky, my guesses really paid off in that I came up with the next guess pretty easily.
Hmm, I just guessed the 1st word I thought of for guess 5, just as well, I do see why so many went with the other word.

1/2 Thanks to @… for this interesting article. It speaks to me. :)
I’ve been weather blogging @… since 2005. It is interesting how it has changed, and how I have changed.
My website used to be just data from the (expensive) station I bought when I moved back to Port Alberni. It was a hobby and a side project to practice web/coding skills I use at work. My focus was on creating useful data for people that was more local/relevant than the official EC station outside of the city.
Then I put up a webcam and learned how to make timelapses. This got the attention of local media… because pictures. :)
Then I added a blog and started to write about the weather almost daily. This was before Facebook. There was a popular local online forum where I would post things. The media would also follow my website and they started to call me when there was extreme weather (usually very hot or very wet/stormy).
Then Facebook started to get big and I made a page that eventually had a few thousand followers. I would blog often. Lots of traffic from Facebook… this was 2010 and on. I blogged about climate and weather pretty equally.
Like anyone in Port Alberni, I was/am obsessed with the Martin Mars and got wrapped up in that issue along with others which combined with the weather following probably gave me just enough exposure to have me elected as a councillor in 2014.
I continued through that 4 years, blogging often in addition to councillor duties and work, heavily on facebook, then it all went sideways on my own poor judgement (go ahead and google it, it’s ok :)) and I was not reelected, but Facebook by 2018 had also changed. Cambridge Analytica, etc.

Seed-dispersing animals are in decline, impacting forests and the climate: Study
A lot of attention has been paid to the decrease in bee populations and other pollinators, but a recent review article makes the case that we should be equally alarmed by the declining numbers of seed-dispersing animals, which are crucial for growing healthy forests. “Both are important and should be taken into account in restoration […]

RNA-binding antiterminators: regulation of metabolism and pathogenicity in bacteria
Antiterminators are essential components of bacterial transcriptional regulation, allowing the control of gene expression in response to fluctuating environmental conditions. Among them, RNA-binding antiterminator proteins play a major role in preventing transcription termination by binding to specific RNA sequences. These RNA-binding antiterminators have been extensively studied for their role in regulating various metabolic pathways. However, their function in modulating the physiology of pat…

Abstract Landscapes
(Bernina range, on the approach to Lago di Fellaria, Sep 2025)
Everything about this place is so special: the road to the trailhead (with 1700m elevation gain), the scale of the majestic ~4000er (meters) mountains with their glaciated peaks. Observing the different levels/layers of this upper valley where the glaciers have already mostly receded, the parts which have been flooded with a reservoir (slowly drying out), the equally spectacular & tragic waterfa…
