Think about this, China manufactures around:
85% of the world’s solar panels
80% of batteries
68% of wind turbines
70% of electric vehicles, and
65% of energy storage systems

I posted the same solar facts on two social media platforms: One sparked discussion, the other, disinformation
One hundred solar panels per second reflects extraordinary technical progress. A platform that simply fosters noise over truth does not.

Feel for Spurs fans as that was late misfortune in regulation followed by absolute ineptitude in penalties.

xAI Was About to Land a Major Government Contract. Then Grok Praised Hitler
Internal emails obtained by WIRED show a hasty process to onboard OpenAI, Anthropic, and other AI providers to the federal government. xAI was on the list—until MechaHilter happened.

arxiv_citation: arXiv citation networks (1993-2003)
Citations among papers posted on arxiv.org under the hep-ph and hep-th categories, between 1993 and 2003. This time begins a few months after axiv was launched. If a paper i cites a paper j also in this data set, then a directed edge connects i to j. (Papers not in the data set are excluded.) These data were originally released as part of the 2003 KDD Cup.
This network has 34546 nodes and 421578 edges.

Some More Sparse Bounds for Rough and Smooth Pseudodifferential Operators
D.~Beltran and L.~Cladek (arXiv:1711.02339) use $L^r$ to $L^s$ bounds to prove sparse form bounds for pseudodifferential operators with Hörmander symbols in $S^m_{ρ,δ}$ up to, but not including, the sharp end-point in decay $m$. We further develop their technique, obtaining pointwise sparse bounds for rough pseudodifferential operators that are merely bounded in their spatial variables and an alternative proof of their results which avoids proving geometrically decaying sparse bounds. We als…

physics_collab: Multilayer physicist collaborations (2015)
Two multiplex networks of coauthorships among the Pierre Auger Collaboration of physicists (2010-2012) and among researchers who have posted preprints on arXiv.org (all papers up to May 2014). Layers represent different categories of publication, and an edge's weight indicates the number of reports written by the authors. These layers are one-mode projections from the underlying author-paper bipartite network.
