My usual sentiment for this US holiday: If you're observing it in some way, I hope it's a good day with family, or a friendsgiving if family isn't an option.
If you aren't, have a good Thursday. Ignore the doom for a day. Don't worry, it'll still be there tomorrow.
As for me, I'm going to the parent's where I will be avoiding most of the food (many thyroid surge triggers so I gotta be careful) and upgrading Dad's 8yr old Acer lappy with an SS…

High-precision luminescence cryothermometry strategy by using hyperfine structure

Abstract: A novel, to the best of our knowledge, ultralow-temperature luminescence thermometry strategy is proposed, based on a measurement of relative intensities of hyperfine components in the spectra of Ho$^{3 }$ ions doped into a crystal. A $^{7}$LiYF$_4$:Ho$^{3 }$ crystal is chosen as an example. First, we show that temperatures in the range 10-35 K can be measured using the Boltzmann behavior of the populations of crystal-field levels separated by an energy interval of 23 cm$^{-1}$. Then we select the 6089 cm$^{-1}$ line of the holmium $^5I_5 \rightarrow ^5I_7$ transition, which has a well-resolved hyperfine structure and falls within the transparency window of optical fibers (telecommunication S band), to demonstrate the possibility of measuring temperatures below 3 K. The temperature $T$ is determined by a least-squares fit to the measured intensities of all eight hyperfine components using the dependence $I(\nu) = I_1 \exp(-b\nu)$, where $I_1$ and $b = a\nu \frac{\nu}{kT}$ are fitting parameters and a accounts for intensity variations due to mixing of wave functions of different crystal-field levels by the hyperfine interaction. In this method, the absolute and relative thermal sensitivities grow at $T$ approaching zero as $\frac{1}{T^2}$.and $\frac{1}{T}$, respectively. We theoretically considered the intensity distributions within hyperfine manifolds and compared the results with experimental data. Application of the method to experimentally measured relative intensities of hyperfine components of the 6089 cm$^{-1}$ PL line yielded $T = 3.7 \pm 0.2$ K. For a temperature of 1 K, an order of magnitude better accuracy is expected.

So I grew up next to #Chernobyl and this is, well, TERRIFYING.
A story for y’all: I’m from a city called Zhytomyr, 2 hours west of Kyiv in the North of #Ukraine. We were downwind of the Chernobyl #nuclear power plant when the 1986 disaster happened.
I wasn’t born for another 12 years, but my childhood was filled with stories and the aftermath of it all. Things like:
- My grandmother worked as a head doctor in a hospital and rehabilitation facility exclusively for children of Chernobyl victims to treat the extremely high prevalence of Tuberculosis and other severe health complications. (To specify: these were SECOND GENERATION of exposure).
- A lot of the kids in that facility were orphans, because their parents died young from health problems.
- My uncle’s wife was born in Pripyat. She was 1 year old when the disaster happened. Her parents were told to evacuate while given no information about what happened. They had to pack up their things and rush out to an unfamiliar city with their baby, never to see the rest of their belongings, apartment, or hometown again.
- When I was a kid, it became so common to see weirdly mutated animals and insects that even 2-3 year olds would make jokes about “Chernobyl mosquitos” and I wouldn’t even flinch seeing occasional giant bugs, dark frogs, weird-looking dogs.
- We’d frequently hear of nearby farms having issues with their animals being born too mutated to survive or random outbreaks from contaminated water / food. Crops would randomly fail. People would get poisoned on a regular basis. This all got less common as I grew up.
- My mother still remembers being a little girl, 10 years old, and looking outside from their balcony at the clouds blowing over from Chernobyl that day. People were told to not go outside and to shut all the windows, but not given an explanation as to why. My mother swears that the rain looked different. They weren’t able to go and buy more food for the kitchen for multiple days.
Anyway - nuclear safety isn’t a joke. I don’t understand how this level of carelessness can happen after Chernobyl and Fukushima.

Just ran across https://openwebsearch.eu/news/ for the first time. A small number of years ago I would have called the idea ridiculous. Now I think that, if you got the right people together, it could have a good outcome.

If you are into #3dPrinting and use resin printers (as opposed to the more well known FDM ones, using filament), you might be interested in this campaign trying to develop a #slicer application for resin printers:

As some of you may know, I spent a gazillion years as a media/telecom analyst but have been strictly cyber for ten years now.
But TechTarget commissioned me to write a series of "pillar" pieces on 5G and here's the first.
Thanks to Tom Pace of NetRise, Jack Fritz of Deloitte and Dave Krauthamer of QuSecure for their insights.
