Ich habe mal für K2 eine Lampe gedruckt. Im Moment der Aufnahme ist sie ausgeschaltet... Lumineszierendes Filament machts möglich!

First Lasing and Stable Operation of a Direct-Amplification Enabled Harmonic Generation Free-Electron laser
Seeded free-electron lasers (FELs) capable of operating at repetition rates up to the MHz level are in high demand for advanced time-resolved spectroscopies, which require both full longitudinal coherence and high average photon flux in the extreme ultraviolet (EUV) and x-ray regimes. However, conventional external-seed laser systems cannot sustain MHz operation with sufficient hundreds of megawatts peak power requirement due to their limited total power. Here, we report the first lasing and st…

Y'all were wondering which way the army would break. This is as clear an answer as you're going to get.
This isn't a mistake. It's a message.
Edit: cut out "During drills they were perfectly in time" because I don't have receipts to show. Linking to a longer video in a threads post that shows a bit more intense of a juxtaposition between themselves and the division in front of them. This thread makes the same claim about drills, but I also don't see video.

Edit: to clarify a bit, this is one division. The division in front of them in the longer video is in step. This isn't "the whole army is going to refuse" but this may be, "some units are fed up enough to make it clear they don't want to play, which is saying a lot."
Any division that exists needs to be cultivated. The way you cultivate that is absolutely not by lumping them all together. Some of the military voted for Trump, some don't care, some hate him. All of them are being treated like shit right now. All of them swore an oath to defend the constitution. Some of them probably know what that means.
I'm absolutely not a fan of the military, but I will take every opportunity I can to humanize these folks. Look for every opportunity you can to remind them that they are welcome on our side whenever they're ready to actually fulfill their oath, and we will appreciate every subtle bit of resistance they give to those who are violating it in the meantime.

A Step-by-Step Guide to Creating a Robust Autonomous Drone Testing Pipeline
Autonomous drones are rapidly reshaping industries ranging from aerial delivery and infrastructure inspection to environmental monitoring and disaster response. Ensuring the safety, reliability, and efficiency of these systems is paramount as they transition from research prototypes to mission-critical platforms. This paper presents a step-by-step guide to establishing a robust autonomous drone testing pipeline, covering each critical stage: Software-in-the-Loop (SIL) Simulation Testing, Hardwa…

Ich, singend:
Schmetterling kommt nach Haus
Kleiner Bär kommt nach Haus
Känguru kommt nach Haus
Die Lampen leuchten, der Tag ist aus
Alles schläft und alles wacht
Alles weint und alles lacht
Alles schweigt und alles spricht
Alles weiß man leider nicht
Kind, hellwach:
Das wäre auch sehr langweilig!

Sort of mind-blowing anecdote during my #leukemia treatment. Between hospitalizations I had outpatient clinic visits twice a week. My first time there I was sitting in the waiting room with 4 or 5 other patients, who were chatting.
One of the guys was talking about his experience getting CAR T treatment for lymphoma. CAR T is a fairly new, very high tech intervention. The man then veered …

Als vor gut zehn Jahren der Journalist und LGBTQ -Aktivst Eric Lembembe in seiner Wohnung in Jaunde ermordet wird, beginnt der in Kamerun geborene Berliner Regisseur Appolain Siewe sich mit der grassierenden Homophobie in Kamerun zu beschäftigen. Sein Dokumentarfilm CODE DER ANGST zeigt Siewes Versuch, die Ursachen des Hasses zu verstehen.

Doku über Homosexualität in Kamerun: Suchen gegen alle Widerstände
Wer sich engagiert, muss mit Repression rechnen: Der Dokumentarfilm „Code der Angst“ von Appolain Siewe geht der Homophobie in Kamerun nach.

I'm pretty sure all the white folks (and anyone else who didn't learn the underlying lessons first hand) were assigned to learn about Red Summer, the Chinese Exclusion Acts, Wilmington 1898, and more than a few other things that came up in cultural conversation during the last Trump presidency. This is all on the test, and you're taking it now.
But in case anyone missed the assignment, I'll give you the TL;DR: ethnic cleansing has been central to American politics basically forever, which shouldn't be surprising given it's a nation founded on genocide and the belief in the right to commit it without constraint.
If you haven't done the math yet, I'll help you out. The "Haitian Immigrants" lets them grab black folks, they've been grabbing folks from Mexico south and lumping in indigenous Americans (just so they don't skip out on the oldest American genocide), and the Muslim ban/Hamas rhetoric lets them grab anyone who else they see fit.
The lack of due process lets them grab anyone and they don't have to prove anything. They're talking about deporting "one million" and possibly"millions" of people. So how do they get those numbers?
There are already reports that they're just grabbing random brown folks, trying to take 3k people per day. They fly to blue cities and grab as many black and brown people as they can, then send them to death camps in foreign countries and pretend they have no way to get them back. That's it. That's the game.
This isn't new. The big difference now is that the cops aren't hiding their uniforms under white hoods this time. Do you get it yet?

On a nonlinear Schrödinger-Bopp-Podolsky system in the zero mass case: functional framework and existence
In this paper, we consider in $\mathbb{R}^3$ the following zero mass Schrödinger-Bopp-Podolsky system \[ \begin{cases} -Δu +q^2ϕu=|u|^{p-2}u\\ -Δϕ+a^2Δ^2ϕ=4πu^2 \end{cases} \] where $a>0$, $q\ne 0$ and $p\in (3,6)$. Inspired by [Ruiz, Arch. Ration. Mech. Anal. 198 (2010)], we introduce a Sobolev space $\mathcal{E}$ endowed with a norm containing a nonlocal term. Firstly, we provide some fundamental properties for the space $\mathcal{E}$ including embeddings into Lebesgue space…

MERIT: Multilingual Semantic Retrieval with Interleaved Multi-Condition Query
Semantic retrieval is crucial for modern applications yet remains underexplored in current research. Existing datasets are limited to single languages, single images, or singular retrieval conditions, often failing to fully exploit the expressive capacity of visual information as evidenced by maintained performance when images are replaced with captions. However, practical retrieval scenarios frequently involve interleaved multi-condition queries with multiple images. Hence, this paper introduc…
