  1. Evidence is accumulating that patterns of use for singular “they” are changing in English. The pronoun is becoming the preferred generic when the gender of the referent is unknown or backgrounded. This change reflects a shift in patterns of acceptability for uses of singular “they” which is in turn linked to the increased frequency of singular they. We predict that adaptation may be a cognitive mechanism underlying this change, and if so, we may see short-term adaptation within a lab session. In the present study, we use a between-subjects priming paradigm to test whether participants adapt to the frequency with which they encounter singular or plural senses of “they” in the local discourse. We find that selections of singular “they” are significantly more likely after participants have been exposed to unambiguously singular vs. plural uses of “they”. This finding implicates adaptation and suggests that adaptation may link changes in the frequency of linguistic forms to changes in their acceptability.

  2. Class J has introduced a new rigorous framework for designing broadband PAs. However, the design of broadband Class-J amplifiers remains challenging, as the fundamental impedance termination is non-Foster when the 2 nd harmonic is Foster. In addition the peak instantaneous voltage varies by up to 50% as the frequency changes. In this paper, a generalized Class-J theory is introduced. Then a DC tunable broadband PA with constant instantaneous peak voltage and Foster fundamental and harmonic terminations is proposed.

  3. A bstract We study Euclidean D3-branes wrapping divisors D in Calabi-Yau orientifold compactifications of type IIB string theory. Witten’s counting of fermion zero modes in terms of the cohomology of the structure sheaf $$ {\mathcal{O}}_D $$ O D applies when D is smooth, but we argue that effective divisors of Calabi-Yau threefolds typically have singularities along rational curves. We generalize the counting of fermion zero modes to such singular divisors, in terms of the cohomology of the structure sheaf $$ {\mathcal{O}}_{\overline{D}} $$ O D ¯ of the normalization $$ \overline{D} $$ D ¯ of D . We establish this by detailing compactifications in which the singularities can be unwound by passing through flop transitions, giving a physical incarnation of the normalization process. Analytically continuing the superpotential through the flops, we find that singular divisors whose normalizations are rigid can contribute to the superpotential: specifically, $$ {h}_{+}^{\bullet}\left({\mathcal{O}}_{\overline{D}}\right)=\left(1,0,0\right) $$ h + • O D ¯ = 1 0 0 and $$ {h}_{-}^{\bullet}\left({\mathcal{O}}_{\overline{D}}\right)=\left(0,0,0\right) $$ h − • O D ¯ = 0 0 0 give a sufficient condition for a contribution. The examples that we present feature infinitely many isomorphic geometric phases, with corresponding infinite-order monodromy groups Γ. We use the action of Γ on effective divisors to determine the exact effective cones, which have infinitely many generators. The resulting nonperturbative superpotentials are Jacobi theta functions, whose modular symmetries suggest the existence of strong-weak coupling dualities involving inversion of divisor volumes.
