Quenching of single-particle strength inferred from nucleon-removal transfer reactions on $^{15}$C
The difference in the proton and neutron separation energies ($ΔS$) of the weakly bound $^{15}$C ground state is -19.86 MeV, an extreme value. Data from intermediate-energy heavy-ion induced (HI-induced) knockout reactions on nuclei spanning $-20\lesssimΔS\lesssim+20$ MeV, suggest that the degree to which single-particle strength is quenched, $R\mathrm{_{s}}$, has a negative correlation with $ΔS$, decreasing from unity around $-20$~MeV to around 0.2 at $+20$~MeV. For the $^{15}$C ground stat…

A Positivity-Preserving Finite Element Framework for Accurate Dose Computation in Proton Therapy
We present a stabilised finite element method for modelling proton transport in tissue, incorporating both inelastic energy loss and elastic angular scattering. A key innovation is a positivity-preserving formulation that guarantees non-negative fluence and dose, even on coarse meshes. This enables reliable computation of clinically relevant quantities for treatment planning. We derive a priori error estimates demonstrating optimal convergence rates and validate the method through numerical ben…

Jerry Falwell and #MeToo agree that men who want sex are evil.
When Christian Fundamentalist Conservatives and Radical Feminists agree, people who still have some common sense need to stick together and fight for sanity.

The Democrats Are Now The Moral Majority - in the worst possible way One of the most fascinating things in the last few decades of U.S. politics is the total reversal of the sex-positive vs sex-negative positions of the two main parties. In the 80s and 90s the Republicans were the party of Jerry Falwell and the Moral Majority. The sex-phobic Puritan idiots were all in the GOP. The sex-positive enjoy life and don't suppress healthy natural desires party was the Democrats. In the 90s the …
