Paracapnia baumanni sp. n. is described from northern California. The apterousnew species is related to P. humboldta and P. boris by sharing the mesosternal postfurcasternal plates separated from the spinasternum, but the epiproct of the new species is shorter, widest in the middle, and lacking an u ...

Isoperla laucki sp. n. and I. karuk sp. n. are described from the Coast Range in northwestern California. Isoperla laucki is shown to be a peculiar member of the genus in western North America based on the male aedeagus, female egg and color pattern of the nymph. Isoperla karuk is included in the Is ...

We use Higgs bundles to study the 3D N = 1 vacua obtained from M-theory compactified on a local Spin(7) space given as a four-manifold M-4 of ADE singularities with further generic enhancements in the singularity type along one-dimensional subspaces. There can be strong quantum corrections to the ma ...

Orbifold singularities of M-theory constitute the building blocks of a broad class of supersymmetric quantum field theories (SQFTs). In this paper we show how the local data of these geometries determine global data on the resulting higher symmetries of these systems. In particular, via a process of ...

Generalized global symmetries are a common feature of many quantum field theories decoupled from gravity. By contrast, in quantum gravity/the Swampland program, it is widely expected that all global symmetries are either gauged or broken, and this breaking is in turn related to the expected complete ...

The stringy realization of generalized symmetry operators involves wrapping “branes at infinity”. We argue that in the case of continuous (as opposed to discrete) symmetries, the appropriate objects are fluxbranes. We use this perspective to revisit the phase structure of Verlinde’s monopole, a prop ...
