Apart from being cruel this is probably a criminal act - not much different then sitting on a sidewalk and shooting passer-by with a BB-gun.
My city (Santa Cruz) installed these machines to drive homeless people away from some tunnels where assaults had been happening. I went there - but the version used there was tuned to be detectable only by ears younger than my own, but I did get the queasy sensation.
In any case, I would consider these to be a form of criminal (and also civ…

Hey, wait a minute: on at-issue sensitivity in Language Models
Evaluating the naturalness of dialogue in language models (LMs) is not trivial: notions of 'naturalness' vary, and scalable quantitative metrics remain limited. This study leverages the linguistic notion of 'at-issueness' to assess dialogue naturalness and introduces a new method: Divide, Generate, Recombine, and Compare (DGRC). DGRC (i) divides a dialogue as a prompt, (ii) generates continuations for subparts using LMs, (iii) recombines the dialogue and continuations, and (iv) compares the lik…

I’m generally a fan of Mission Local, so it’s disappointing when even they echo copaganda like “The SFPD staffing crisis is real and costs the city a fortune in overtime.”
A staff shortage is SFPD’s opinion, and the linked article itself attributes the overtime cost to “potential abuse.”

The District 4 supervisor race will be nasty, brutish — and short
The Sunset has a new supervisor — and a bruising, reductive and rapid election on the horizon

In the closing days of the Biden administration, deputy national security adviser for cyber and emerging technology Anne Neuberger warned,
“China is targeting critical infrastructure in the United States.”

That sounds like the sort of thing the U.S. government might want to do something about.
But apparently not;
On Dec. 3, the Financial Times reported that the Trump administration had
“halted plans to impose sanctions on China’s Ministry of State Security

What Trump lets China do for buying U.S. soybeans
The president is buddy-buddy with Xi and won’t let cyberattacks or saber-rattling get in the way.

Proprioceptive Misestimation of Hand Speed
The accuracy with which the human proprioceptive system estimates hand speed is not well understood. To investigate this, we designed an experiment using hobby-grade mechatronics parts and integrated it as a laboratory exercise in a large remote laboratory course. In a simple joint position reproduction task, participants (N = 191) grasped a servomotor-driven shaft with one hand as it followed a randomized trajectory composed of sinusoidal submovements. They simultaneously attempted to reproduc…

Deep XMM-Newton observation reveals hot gaseous outflow in NGC 5746
Context. We present a deep XMM-Newton observation of the massive, edge-on galaxy NGC 5746. The total exposure time of 250 ks provides unprecedented sensitivity to study the diffuse hot gas in the halo, significantly surpassing the depth of previous observations. Aims. While the presence of hot, circumgalactic gas is well tested for starburst galaxies, detections in normal galaxies remain scarce. By studying the diffuse X-ray emission in NGC 5746, we aim to provide new insights into the evolutio…

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.
