NIH scientists go public with criticism over Trump cuts
President Donald Trump’s National Institutes of Health director says some employees’ critical letter to him has “fundamental misconceptions about the policy directions the NIH has taken.” Monday’s letter from NIH researchers and staffers says the Republican Trump administration’s policies waste public resources and harm people’s health. NIH Director Jay Bhattacharya in his confirmation hearings pledged openness to views that might conflict with his, saying dissent is the “essenc…

On Monday, scores of scientists at the National Institutes of Health sent their Trump-appointed leader a letter titled the "Bethesda Declaration"
challenging “policies that undermine the NIH mission, waste public resources, and harm the health of Americans and people across the globe.”
It says: “We dissent.”
In a capital where insiders often insist on anonymity to say such things publicly,
92 NIH researchers, program directors, branch chiefs and scientific r…

2N-storage Runge-Kutta methods: c-reflection symmetry and factorization of the Butcher tableau
Low-storage Runge-Kutta schemes of Williamson's type, so-called 2N-storage schemes, are further examined as a follow-up to the recent work. It is found that the augmented Butcher tableau factorizes into a product of matrices with special properties. Those properties reveal that the 2N-storage methods of the order of global accuracy less than five possess a symmetry, called c-reflection symmetry, i.e. most methods exist in pairs. A transformation that relates the Butcher tableaux of the pairs is…

Perfect state transfer in Grover walks on association schemes and distance-regular graphs
This paper investigates perfect state transfer in Grover walks, a model of discrete-time quantum walks. We establish a necessary and sufficient condition for the occurrence of perfect state transfer on graphs belonging to an association scheme. Our focus includes specific association schemes, namely the Hamming and Johnson schemes. We characterize all graphs on the classes of Hamming and Johnson schemes that exhibit perfect state transfer. Furthermore, we study perfect state transfer on distanc…
