baseball: Baseball steroid use (2008)
Two networks representing steroid use among baseball players. First, a bipartite network of players and their steroid providers (of illegal performance-enhancing substances). Second, a one-mode projection of players, which are linked if they have a common supplier.
This network has 84 nodes and 84 edges.

As Donald Trump ramped up his threats against the people he is supposed to be working for,
his administration’s extreme immigration enforcement led Homeland Security Secretary Kristi Noem to admit that anyone
— U.S. citizen or otherwise
— should be prepared to have to prove their citizenship to DHS agents.
Asked Thursday about U.S. citizens being asked to provide proof of citizenship in Minnesota
and whether that is “targeted enforcement,”
Noem said the f…

Noem says that virtually anyone could face a Kavanaugh stop
Trump started off the day with an Insurrection Act threat. Noem followed up by saying that anyone "surrounding" any DHS target has to prove their legal status.

An x-ray regenerative amplifier free-electron laser with a step-tapered-undulator

Abstract: Regenerative amplifier x-ray free-electron lasers constitute alternative configurations for fourth generation light sources which are typically operated in self-amplified spontaneous emission (SASE) mode. However, SASE exhibits relatively large fluctuations in the power and spectral properties from shot to shot, whereas XRAFELs provide a much more stable source of hard x-ray photons. Here, we study the performance of an x-ray cavity under consideration at the Stanford Linear Accelerator Facility using both uniform and step-tapered undulators with either transmissive or hole out-coupling.

Meta’s Oversight Board warns that “Community Notes” aren’t a proper substitute for fact-checking globally
On Thursday, Meta’s Oversight Board, a quasi-independent body that reviews the social media giant’s moderation practices, ruled that “Community Notes” are not a proper substitute for its fact-checking program. In a new “policy advisory opinion," the Board expressed concerns about …

What the heck?
I kept hearing mooing today.
Went out back to look and the neighbor has 4 calves in a fenced in area.
I ignored when he brought in 8 chickens even though you are only supposed to have 3 and no roosters which he has one of. But cattle? And a goat But looks like someone beat me to it as the sheriff pulled up while I was looking. Said the people on the other side of the creek reported what sounded like an animal in distress.
Looks like he now has a proble…

Application of RFSoC Technology for Beam Position Monitors at the SuperKEKB Storage Rings Injection Points

https://arxiv.org/abs/2602.14870 https://arxiv.org/pdf/2602.14870 https://arxiv.org/html/2602.14870
arXiv:2602.14870v1 Announce Type: new
Abstract: In order to achieve its ambitious luminosity target, the SuperKEKB collider must achieve and sustain high beam currents on the order of Ampere in its storage rings. This requires continuous top-up injection and operation with a two-bunch injection scheme, injecting two 96 ns spaced bunches in a single injection cycle. An important input for tuning the injection beam is the position reading from a dedicated beam position monitor (BPM), located after the septum magnets, slightly upstream of where the injected and stored beams converge. Previously, the readout electronics used for these special BPMs were not capable of independent measurement of both bunches in the two-bunch injection mode and modification of the concerned devices and their firmware was not feasible. The opportunity was taken to develop a new readout device based on the AMD/Xilinx RF System on a Chip (RFSoC) platform with the goal of not only providing a sufficiently flexible and performant readout solution for the concerned BPMs, but also to evaluate and gain experience with the platform for beam monitor electronics applications. This paper is concerned with the details of this development as well as evaluation and operation of the developed device.
