Faster Gravitational Wave Signals with Multiband Quadratures
![The study demonstrates that likelihood errors-calculated between full and reduced order quadrature (ROQ) likelihoods, and further refined with a multiband approach-remain consistently below a threshold of [latex] 7\times 10^{-3} [/latex] across 6400 randomly sampled gravitational waveforms drawn from a 256-second basis parameter space, suggesting a high degree of accuracy in the reduced models.](https://arxiv.org/html/2601.09819v1/x2.png)
A new approach to constructing gravitational wave signals significantly speeds up data analysis by efficiently building the necessary mathematical basis.

During a conference, His Excellency confided that he prefers to keep Hassett in his current role, citing the usual concerns about upheaval and the possibility of losing a committee member who probably knows where the coffee is brewed.

Koyoharu Gotoutge, the creator of Demon Slayer, has mentioned two anime that directly inspired the series, and it’s clear that four others likely played a role. Fortunately, Demon Slayer didn’t just copy these earlier works; it took inspiration from them while still crafting its own unique and emotional story about the human condition.

Legion Remix was a special, temporary game mode available from October 7, 2025. It let players quickly experience the popular Legion expansion, easily earn unique cosmetic items, level up their World of Warcraft characters faster than usual, and unlock lots of achievements. Unfortunately, the event is ending with the release of the WoW: Midnight Pre-Expansion Update on January 20th.

Chapter 30 of Boruto: Two Blue Vortex is coming soon, and fans are eager to see what happens next with the story arc centered around Shinju Mamushi. Over the past few chapters, we’ve watched the Konoha ninja get ready for Mamushi’s attack, and they handled it effectively. Inojin’s efforts helped keep Mamushi and his clones contained, and Boruto’s newly awakened powers made defeating the clones surprisingly easy.

Okay, so Season 1 of Battlefield 6 has been… a bit of a rollercoaster, honestly. They launched that new RedSec mode – their take on Battle Royale – and while it’s cool, it hasn’t exactly taken the world by storm. Plus, the main game itself had a lot of issues, and people weren’t thrilled with some of the rewards and how the AI worked. It’s gotten to the point where the player numbers are really worrying. But the team at DICE and the other studios are determined to fix things, and they’re hoping this first update of 2026 will be the start of a big turnaround. I’m really hoping they can pull it off!

In Heartopia, you can get your first pet once you become a D.G. Member at Level 12. Reaching this level will start a quest that takes you to Mrs. Joan and the Adoption Center.

2026 promises a ton of exciting new games, like Marvel’s Wolverine and Resident Evil: Requiem, leaving players with more options than ever. However, there are a few upcoming titles it’s best to hold off on preordering. It’s not that these games look bad, but they’re taking such unique and untested approaches that it’s hard to predict whether they’ll deliver on their potential, so waiting for more information is a good idea.

Goku doesn’t defeat every bad guy he faces, which allows other characters in the Dragon Ball series to have their moments. Looking at Dragon Ball Z, Goku only truly defeats a handful of major villains: Nappa, Recoome, Burter, Frieza, Yakon, and Majin Buu – though some of those, like Nappa, Recoome, Burter, and Yakon, aren’t really that significant. His win rate is even lower in Dragon Ball Super, but the manga does give him some important victories against Moro and Granolah.
