Quasi-triangular and factorizable dendriform D-bialgebras
In this paper, we introduce the notions of quasi-triangular and factorizable dendriform D-bialgebras. A factorizable dendriform D-bialgebra leads to a factorization of the underlying dendriform algebra. We show that the dendriform double of a dendriform D-bialgebra naturally enjoys a factorizable dendriform D-bialgebra structure. Moreover, we introduce the notion of relative Rota-Baxter operators of nonzero weights on dendriform algebras and find that every quasi-triangular dendriform D-bialgeb…

Oriented Diameter of Mixed Graphs with Given Maximum Undirected Degree
In 2018, Dankelmann, Gao, and Surmacs [J. Graph Theory, 88(1): 5--17, 2018] established sharp bounds on the oriented diameter of a bridgeless undirected graph and a bridgeless undirected bipartite graph in terms of vertex degree. In this paper, we extend these results to \emph{mixed graphs}, which contain both directed and undirected edges. Let the \emph{undirected degree} $d^*_G(x)$ of a vertex $x \in V(G)$ be the number of its incident undirected edges in a mixed graph $G$ of order $n$, and…

Vintage NPOI: New and Updated Angular Diameters for 145 Stars
We present new or updated angular diameters, physical radii, and effective temperatures for 145 stars from the Navy Precision Optical Interferometer data archive. We used data from 1996 to late-2021, and we describe the differences between early and late data, which hinge upon an update of the beam combiner in 2002. We came across several sub-categories of stars of interest: 13 of our stars are promising targets for the Habitable World Observatory and therefore require as much study as possible…

Timothy Snyder:
The people described as "undocumented" or "denaturalized"
(and other categories sure to be invented soon)
are portrayed as criminals.
If the Trump regime tries to enslave such people on a large scale, there will be a court case.
But waiting for the Supreme Court to do the right thing is, to put it gently, no substitute for action.
It would be good if there were explicit legislation banning slave labor in all circumstan…
