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?

Quantum spheres as graph and groupoid C*-algebras
In this review, we illustrate the description of Vaksman-Soibelman quantum spheres using graph and groupoid C*-algebras following the seminal works of Hong-Szymański and Sheu, and discuss the interplay between these two pictures. In particular, we prove that the graph groupoid of the directed graph of a quantum sphere is isomorphic to the groupoid introduced by Sheu in the 1990s. We also show that, while the universal C*-algebra of a quantum sphere is independent of the deformation parameter q…

Graphs of bounded chordality
A hole in a graph is an induced subgraph which is a cycle of length at least four. A graph is chordal if it contains no holes. Following McKee and Scheinerman (1993), we define the chordality of a graph $G$ to be the minimum number of chordal graphs on $V(G)$ such that the intersection of their edge sets is equal to $E(G)$. In this paper we study classes of graphs of bounded chordality. In the 1970s, Buneman, Gavril, and Walter, proved independently that chordal graphs are exactly the interse…

Theory of a Strange Metal in a Quantum Superconductor to Metal Transition
Recent experiments with nanopatterned thin films revealed an unusual quantum superconductor to metal phase transition (QSMT) with a linear in temperature resistivity. In contrast, most known examples of such transitions and standard theoretical considerations predict a temperature-independent sheet resistance of order $R_Q = \frac{\hbar}{e^2}$. We propose an effective theory of a disordered superconductor which features a QSMT with robust $T$ linear resistivity at the critical point. The crucia…

Genetic Composition of Supercritical Branching Populations under Power Law Mutation Rates
We aim at understanding the evolution of the genetic composition of cancer cell populations. To this aim, we consider a branching individual based model representing a cell population where cells divide, die and mutate along the edges of a finite directed graph $(V,E)$. The process starts with only one cell of trait $0$. Following typical parameter values in cancer cell populations we study the model under \textit{large population and power law mutation rates limit}, in the sense that the mutat…
