Because of the coast’s huge value, municipalities often choose to manicure their sandy beaches regularly, grooming them sometimes twice daily in high season. Conservationists and scientists have expressed concerns the practice could be harmful to birds and other wildlife species that reproduce and forage on the coast. Many of these coastal species, particularly shorebirds, have already lost a great majority of their native coastal and wetland habitats to development.

Although notorious for clogging pumping stations, eroding levees and stealing bait, the Chinese mitten crab poses a perhaps equally significant, albeit less recognized, human health threat as a host for a group of parasites known as lung flukes. Flukes, which come in Asian and North American varieties, can be acquired by eating uncooked or under-cooked infected mitten crabs. People infected with flukes may develop tuberculosis-like symptoms, resulting in permanent lung damage. Flukes can also track into the brain.

The same waves that pound the shore off California also tear large amounts of seaweed from the region’s giant kelp forests and rocky reefs. Much of this drift seaweed, known as wrack, is eventually washed ashore. On many of Southern California’s beaches, tractors will remove this wrack (along with trash and litter) and rake the sand, in a process known as beach grooming.

Two double-focusing magnetic specrometers will be used to momentum analyze the electron beam produced by the l'OASIS laser plasma wakefield accelerator. One spectrometer, based on a round pole magnet, has an operating range up to 50 MeV/c, with a resolution in the 1 - 2 percent range. The other spectrometer, based on a wedge dipole magnet, has better resolution (about 0.5 percent) but an operating range limited to below 18 MeV/c. This note describes the optical design of the spectrometers, and provides detailed estimates of performance features such as dynamic range, operating range, calibration, resolution, acceptance, and aberrations.

In 2021, authors Biswal, Chari, Shereen, and Wand showed for the type $A$ current algebra that under suitable conditions on pairs of dominant integral weights $(\nu,\lambda)$ that the fusion product of a local Weyl module with a level 2 Demazure module $D(2,\lambda) * W_{\loc}(\nu)$ is isomorphic to the module $M(\nu,\lambda)$ first introduced by Wand in his 2015 PhD thesis. The work of this thesis is to remove the condition on $(\nu,\lambda)$ by defining new modules $N(\nu,\lambda,\gamma)$ which in the case when $\gamma=0$ are isomorphic to $M(\nu,\lambda)$. We then construct short exact sequences that show under suitable conditions on $(\nu,\lambda,\gamma)$ that the modules $N(\nu,\lambda,\gamma)$ are isomorphic to the fusion product $W_{\loc}(\nu)*D(2,\lambda)*D(2,\gamma)$. In particular, when $\gamma=0$, this gives us the desired isomorphism for $M(\nu,\lambda)$ for all pairs $(\nu,\lambda)$. This allows us to define the fusion product of a local Weyl module and a level 2 Demazure module via generators and relations.
