What's particularly muddy right now is
how a rising number of cattle infections are impacting farm workers,
beyond the Texas case that occurred back in March.
Veterinarians and physicians in states with dairy cattle outbreaks told The Associated Press there are multiple reports of farm workers falling sick,
but confirming cases is proving challenging for one key reason:
Many workers are reluctant to get tested.
"You have groups of individuals that…

What would it take to spark an H5N1 bird flu pandemic? And how bad would it be? | CBC News
For several decades, scientists have rung alarms that a dangerous form of bird flu had pandemic potential. As H5N1 spreads to more species, including U.S. dairy cattle, how likely is that worst-case scenario?

Seymour's second neighbourhood conjecture: random graphs and reductions
A longstanding conjecture of Seymour states that in every oriented graph there is a vertex whose second outneighbourhood is at least as large as its outneighbourhood. In this short note we show that, for any fixed $p\in[0,1/2)$, a.a.s. every orientation of $G(n,p)$ satisfies Seymour's conjecture (as well as a related conjecture of Sullivan). This improves on a recent result of Botler, Moura and Naia. Moreover, we show that $p=1/2$ is a natural barrier for this problem, in the following sense: f…

On a Conjecture Concerning the Roots of Ehrhart Polynomials of Symmetric Edge Polytopes from Complete Multipartite Graphs
In [7], Higashitani, Kummer, and Michałek pose a conjecture about the symmetric edge polytopes of complete multipartite graphs and confirm it for a number of families in the bipartite case. We confirm that conjecture for a number of new classes following the authors' methods and we present a more general result which suggests that the methods in their current form might not be enough to prove the conjecture in full generality.

Symmetry of graphs and perfect state transfer in Grover walks
We study relationships between symmetry of graphs and perfect state transfer in Grover walks. Symmetry of graphs mathematically refers to automorphisms of graphs. When perfect state transfer occurs between two vertices, the following two statements hold. One is that automorphisms preserve the occurrence of perfect state transfer. The other is that the stabilizer subgroups of the automorphism groups with respect to those two vertices coincide. Using these results, we completely characterize circ…
