Good Morning #Canada
This week, in 2022, gold miners in the Yukon discovered a near complete, mummified baby woolly mammoth. The Yukon has a world-renowned fossil record of ice age animals, but mummified remains with skin and hair are rarely unearthed. Geologists, with the Yukon Geological Survey and the University of Calgary, traveled 6 hours to the site and retrieved the remains less than an hour before a storm struck.

Krugman outlines a constellation of possible causes around a core theme: extreme uncertainty.
“What does a business do in the face of this kind of uncertainty? It tries to avoid making commitments that it may soon regret.”
Krugman tries to tie it all to Trump’s recent actions, which is dubious: the post-college job market has been crap since 2022 or 2023; Krugman’s own graph suggests it started worsening circa 2018. The larger theme of uncertainty, however, fits that timeframe.

Ndamukong Suh announces NFL retirement, honors late father in emotional farewell https://www.nytimes.com/athletic/6489892/2025/07/12/ndamukong-suh-retirement-nfl-lions/

I’m so proud of my little brother.
I just spoke to him in his dorm room at a top 30 college here in the US, he just arrived for freshman orientation.
He got in on a full ride - tuition, housing, food, books, travel, stipend for daily expenses. Won a competitive scholarship to do so.
More than that, he’s had a tougher road than most to get there:
- he had to suddenly move away from Manila, Philippines (where he grew up) in middle school because of COVID restrictions that didn’t let kids go outside (2020)
- then, just as he adjusted to school and a different language in our home country, Ukraine, Russia invaded (2022)
- he stayed in Greece for a month while I was calling our congressional representative here in NY and negotiating with the US embassy to get them a visa ASAP to enter the US and be with me and my husband. There were no paths for Ukrainian refugees yet, we just wanted them with us temporarily for a few months to figure out what options they even had next.
- he had to wait, not going to school, with no clue where they’d move next, until TPS became available to Ukrainians and they got to stay here in the US
- then he had to continue high school in yet another system, yet another country, amidst news of bombings and destruction back home
- my mother wasn’t allowed to work for months while their documents were pending, so we had to raise money with a public GoFundMe campaign and my husband and I maxed out our credit cards to help them get by
- they shared a one-room cottage for the first year, graciously hosted for free by an elderly local couple
- he saw a therapist who also graciously took him in for free while they didn’t have insurance
- he had to graduate high school amidst news of other immigrant students getting arrested, detained, and deported at their own graduations around the country
- he wasn’t sure if he would even make it to college as this administration publicly considered canceling TPS for Ukrainians and cutting off their pathway to maintaining legal status.
We don’t know what tomorrow holds. But he’s there. He’s on campus. He got to go to college.
I love him so much.

Galois equiangular tight frames from Galois self-dual codes
Greaves et al. (2022) extended frames over real or complex numbers to frames over finite fields. In this paper, we study the theory of frames over finite fields by incorporating the Galois inner products introduced by Fan and Zhang (2017), which generalize the Euclidean and Hermitian inner products. We define a class of frames, called Galois frames over finite fields, along with related notions such as Galois Gram matrices, Galois frame operators, and Galois equiangular tight frames (Galois ETF…

Loser: U.S. factories
When Democrats in 2022 created and expanded a slew of federal tax breaks for electric vehicles, solar panels, wind turbines, batteries,
they designed them to encourage companies to use components made in the United States.
That spurred a manufacturing boom, including solar-panel glass recyclers in Georgia and electric-vehicle assembly lines in Kentucky.
The new law could derail many of those factories.

Large Language models (LLMs) are transforming digital usage, particularly in text generation, image creation, information retrieval and code development. ChatGPT, launched by OpenAI in November 2022, quickly became a reference, prompting the emergence of competitors such as Google's Gemini. However, these technological advances raise new cybersecurity challenges, including prompt injection attacks, the circumvention of regulatory measures (jailbreaking), the spread of misinformation (hallucinat…

Installation and performance of the 3rd Veto plane at the SND@LHC detector
During 2022/2023 the optimal inefficiency of the Veto system of the SND@LHC detector was measured to be $(7.8\pm2.8)\times10^{-8}$. To reduce this inefficiency, a third Veto plane was installed during the 2023-2024 Year End Technical Stop. In addition, the Veto system was lowered to cover the target fully, thereby increasing acceptance. This paper describes how the inefficiency of the Veto system was reduced from $7.8\times10^{-8}$ with an acceptance of about $64\%$ of the target area in 2022-2…

Coherent electrically-charged quantum black holes
We improve upon the results presented in [R. Casadio, et al., Phys. Rev. D 105 (2022) 124026] deriving a quantum-corrected Reissner-Nordström geometry containing an integrable singularity at its center while being devoid of spurious oscillations around the classical configuration. We further investigate some relevant physical observables, related to geodesics and quasinormal modes of scalar perturbations, associated with this geometry to complement our theoretical analysis.

An SS433 flare caught by TESS. Fast rise times and evidence for a 13 hours quasi-period
SS433 is an exotic Galactic microquasar in which there is a supercritical inflow of matter into a compact object of likely black hole nature. Here we report on an SS433 flare that occurred during a TESS observation of Sector 54 in June of 2022. The flare lasted for about 10 days and culminated in a flux increase by a factor of three relative to quiescence. The unprecedented continuous photometric coverage of the flare afforded by TESS shows that the flux can rise and fall by up to a factor of t…

Multi-wavelength analysis of FSRQ B2 1348+30B: Constraints on the jet power
We present 14.5-year multi-wavelength analysis of flat-spectrum radio quasar B2 1348+30B using Swift-UVOT, Swift-XRT, and Fermi-LAT observations. In the gamma-ray band, the 3 day bin lightcurve reveals two major flaring events on 2010-09-19 (55458 MJD) and 2022-05-26 (59725 MJD) detected at flux levels $(2.5\pm 0.5) \times 10^{-7}\,\rm{ph\,cm^{-2}\,s^{-1}}$ and $(5.2\pm 0.6) \times 10^{-7}\,\rm{ph\,cm^{-2}\,s^{-1}}$.

A natural and short proof of Lee's conjecture on the Frobenius norm
In 2010, Eun-Young Lee conjectured that if $A,B$ are two $n\times n$ complex matrices and $\left|A\right|, \left|B\right|$ are the absolute values of $A, B$, respectively, then \[ \|A+B\|_F\le \sqrt{\dfrac{1+\sqrt{2}}{2}}\|\left|A\right|+\left|B\right|\|_F, \] where $\|\cdot\|_F$ is the Frobenius norm of matrices. This conjecture was initially proven by Lin and Zhang [J. Math. Anal. Appl. 516 (2022) 126542] by studying inequa…

Central Bank Communication with Public: Bank of England and Twitter (X)
Central banks increasingly use social media to communicate beyond financial markets, yet evidence on public engagement effectiveness remains limited. Despite 113 central banks joining Twitter between 2008 and 2018, we lack understanding of what drives audience interaction with their content. To examine engagement determinants, we analyzed 3.13 million tweets mentioning the Bank of England from 2007 to 2022, including 9,810 official posts. We investigate posting patterns, measure engagement elas…

Spectroscopic Observations of Four Candidates for Blue Large-Amplitude Pulsators. No BLAPs at High Galactic Latitudes
We have obtained spectroscopic observations for four short-period variable objects detected in ZTF, Gaia, and Pan-STARRS (ZGP) data and classified as Blue Large-Amplitude Pulsators (BLAPs) in McWhirter and Lam (2022): ZGP-BLAP-03, ZGP-BLAP-04, ZGP-BLAP-10, and ZGP-BLAP-15. The variables have periods between 46 and 56 min, full amplitudes of 0.13-0.22 mag in the $r$ band, and light curve shapes typical for radially pulsating stars. Three of them were found at high galactic latitudes (|$b$&#…
