The Jew in early American literature
Thesis (M.A.)--Boston UniversityIn the essay interest in the Jew had been scholarly rather than humanitarian. In fiction and on the stage the Jew was a blackguard as often as not. But it was in the field of poetry that the Jew received his most sympathetic treatment at the hands of early American writers. The Jew of the poem was thoroughly heroic. If there were a touch of Shylock in his make-up, the poets, at least, did not see it
Dark Radiation from Neutrino Mixing after Big Bang Nucleosynthesis
A light ( MeV) dark fermion mixing with the Standard
Model neutrinos can naturally equilibrate with the neutrinos via oscillations
and scattering. In the presence of dark sector interactions, production of dark
fermions is generically suppressed above BBN, but then enhanced at later times.
Over much of the parameter space, we find that the dark sector equilibrates,
even for mixing angles as small as , and equilibration
occurs at which is naturally at most a few orders of magnitude above the
dark fermion mass. The implications of this are twofold: one, that light states
are often only constrained by the CMB and LSS without leaving an imprint on
BBN, and two, that sectors which equilibrate before recombination will
typically have a mass threshold before recombination, as well. This can result
in dark radiation abruptly transitioning from non-interacting to interacting,
or vice-versa, a ``step'' in the amount of dark radiation, and dark matter with
similar transitions in its interactions, all of which can leave important
signals in the CMB and LSS, and may be relevant for cosmological tensions in
observables such as or . Minimal models leave an unambiguous imprint
on the CMB above the sensitivity of upcoming experiments.Comment: 6 pages, 2 figure
Antibody-Based Immunotherapy of Cancer
By targeting surface antigens expressed on tumor cells, monoclonal antibodies have demonstrated efficacy as cancer therapeutics. Recent successful antibody-based strategies have focused on enhancing antitumor immune responses by targeting immune cells, irrespective of tumor antigens. We discuss these innovative strategies and propose how they will impact the future of antibody-based cancer therapy
