Machine learning approaches to seismic event classification in the Ostrava region
The northeastern region of the Czech Republic is among the most seismically active areas in the country. The most frequent seismic events are mining-induced since there used to be strong mining activity in the past. However, natural tectonic events may also occur. In addition, seismic stations often record explosions in quarries in the region. Despite the cessation of mining activities, mine-induced seismic events still occur. Therefore, a rapid differentiation between tectonic and anthropogeni…

"Creditors circle as cull looms
Jason Proctor
I'm Jason Proctor, a reporter with CBC Vancouver who looked into a series of lawsuits facing the owners of Universal Ostrich Farms Inc.
Last month, I spoke with three creditors who are watching today's ruling with great interest — and some skin in the game.
B.C. Supreme Court judges have ordered the farm's owners to repay debts worth more than $250,000 but, up until now, the creditors have been unable to collect. Normally in this kind of situation, a creditor would move to seize the business assets — but because in this case those assets are ostriches caught up in a legal battle, that's been challenging, to say the least.
All three creditors have tried to garnish the CFIA to intercept any money the agency might pay out as compensation for killing the birds (potentially up to $3,000 a bird, the CFIA says) but it remains to be seen how that will work. The creditors, however, told me they are anxious to recoup their losses.”

[Mal die Rosebar Centrala ausprobiert, nach einigen Empfehlungen im Umfeld: Weine interessant, Speisen fand ich weniger anregend als erhofft -- sehr gut, aber halt jetzt nicht so diese osteuropäische Note, für die das Lokal gepriesen wird. Und diese recht beliebige Speisenfolge beim Sharing-Prinzip, nun ja, damit komm ich einfach nicht klar.]

Fell down a WITSEC rabbit hole courtesy of the YouTube algorithm. Plus, I hit a new bookstore, and decided it was time to close the Mystery Writers Forum.

YouTube's algorithm served up a fascinating story about WITSEC. I hit a new bookstore, and I'm pulling the plug on a longstanding forum.

Happy to see resolution for this case of anti-health, anti-vax, quackery and grifting.
I believe most farmers are ethical and understand that disease within their flocks and herds can and do cause disease in other domestic and wild populations and those diseases are often what causes pandemics in humans.
Avian flu is a danger. Millions of birds have died because of it, and have been culled on other farms to try to control it.
Ostriches are no different.

Good Morning #Canada
In honour of #Caturday, today's post is about the little known Parliament Hill Cat Sanctuary that existed from 1955 to 2013. It was a feline colony for a group of strays living on Parliament Hill in Ottawa, in a sanctuary set aside for them. The care of the cats and maintenance of the sanctuary was carried out by volunteers, and the effort was funded by donations.
Cats were brought into Parliament in 1924 to deal with a "mild plague" of rats and mice in the basement of the then brand-new Centre Block. The numbers of rodents soon fell, but when the unneutered cats began to multiply, they were banished to the outdoors overnight in the same year. In 1955, the cats were replaced by chemicals and no longer allowed access to the Parliament buildings, but the sanctuary was set aside for their colony, and volunteers looked after them for the next 6 decades.

On the threshold behaviour of heavy top production

On the threshold behaviour of heavy top production
The observation of an excess of ttbar production in the threshold region, by CMS and ATLAS, has been interpreted as a toponium contribution, i.e. from below-threshold ttbar virtual states. The news here is the nontrivial experimental extraction of such a signal, not its existence as such. Indeed, already 35+ years ago an NRQCD Green's function approach was used to model the above- and below-threshold production of ttbar pairs in pp/ppbar collisions. The relevant cross section equations from tha…

Programmable Focal Elongation and Shaping of High-Intensity Laser Pulses using Adaptive Optics
Controlling the intensity distribution of laser pulses in the focal region is essential for optimizing optically generated plasma waveguides and enabling advanced plasma acceleration techniques, including dephasingless wakefield acceleration. Here, we present a method for programmatic structuring of the high-intensity focal region of a standard off-axis parabolic mirror, extending the length of this region well beyond the Rayleigh length and enabling control over the longitudinal intensity dist…
