By the way, for anyone around at 20:00 (NZST) today (about 2 hrs from now), we'll be having a FOSS/Libre Meetup up here: https://bbb2.nzoss.nz/rooms/dav-rqm-3fq/join If you're interested, feel free to come along! I might show the FormsBrick system I just set up, and mayb…

A 4-8 GHz Kinetic Inductance Travelling-Wave Parametric Amplifier Using Four-Wave Mixing with Near Quantum-Limit Noise Performance
Kinetic inductance traveling-wave parametric amplifiers (KI-TWPA) have a wide instantaneous bandwidth with near quantum-limited sensitivity and a relatively high dynamic range. Because of this, they are suitable readout devices for cryogenic detectors and superconducting qubits and have a variety of applications in quantum sensing. This work discusses the design, fabrication, and performance of a KI-TWPA based on four-wave mixing in a NbTiN microstrip transmission line. This device amplifies a …

Latest Evolution of the X-Ray Remnant of SN 1987A: Beyond the Inner Ring
Based on our Chandra imaging-spectroscopic observations, we present the latest evolution of the X-ray remnant of SN 1987A. Recent changes in the electron temperatures and volume emission measures suggest that the blast wave in SN 1987A is moving out of the dense inner ring structure, also called the equatorial ring (ER). The 0.5-2.0 keV X-ray light curve shows a linearly declining trend (by $\sim$4.5 % yr$^{-1}$) between 2016 and 2020, as the blast wave heats the hitherto unknown circumstellar …

The predicted result of battery-electric bus mania has arrived.
DC doesn't have enough money to buy electric buses for its Circulator buses, so system will shut down entirely.
(Some routes wil likely be taken over by Metrobus, which still runs diesel buses.)

Circulator bus service could end by March 2025, officials say
The Circulator bus service would need over $100 million to sustain itself next fiscal year.

Rapid identification of time-frequency domain gravitational wave signals from binary black holes using deep learning
Recent developments in deep learning techniques have offered an alternative and complementary approach to traditional matched filtering methods for the identification of gravitational wave (GW) signals. The rapid and accurate identification of GW signals is crucial for the progress of GW physics and multi-messenger astronomy, particularly in light of the upcoming fourth and fifth observing runs of LIGO-Virgo-KAGRA. In this work, we use the 2D U-Net algorithm to identify the time-frequency domai…

"This trend can easily be observed in online chat rooms"
1. Trends cannot be "easily observed".
2. That's not a citation, simply an anecdote.
3. MY DUDE, I was in "online chat rooms" while you were a toddler. You, my most naive incel waif, are in a goddamn Discord room or some bullshit, this isn't fucking CompuServe or the Red Dragon Inn on AOL. (if you refer to Reuters as Usenet next, I will pull this cat over)

One human earth week (March 12) until INP becomes a Core Web Vital, with big implications to the JavaScript-heavy React-ecosystem.
Folks hiding bad lab data (Lighthouse scores) behind decent field data (Core Web Vitals) are right to be nervous about this! Remember that Core Web Vitals affect your SEO/rank on Google 👀

Good morning! Here's a beautiful random pairing I noticed when I went through my Objkt notifications: "Ruins." by @… seems to put the wild 80s to rest, while "New Horizon" by Caving Wilde looks ahead (and doesn't appear to be too optimistic about the outcome).

A Prediction Model for Rumor Forwarding Behavior Based on Uncertain Time Series
The rapid spread of rumors in social media is mainly caused by individual retweets. This paper applies uncertainty time series analysis (UTSA) to analyze a rumor retweeting behavior on Weibo. First, the rumor forwarding is modeled using uncertain time series, including order selection, parameter estimation, residual analysis, uncertainty hypothesis testing and forecast, and the validity of using uncertain time series analysis is further supported by analyzing the characteristics of the residual…
