Significance Vaccines are a key intervention to reduce the burden of COVID-19 pandemic. However, vaccine supply and administration capacity will initially be limited. Due these constraints, it is critical understand how deployment can targeted minimize overall disease. In this paper, we solve for optimal dynamic strategies allocate limited vaccines over population differentiated by age essential worker status that minimizes number total deaths, years life lost, or infections. We find older...
Abstract Multiple promising COVID-19 vaccines are under rapid development, with deployment of the initial supply expected by 2021. Careful design a vaccine prioritization strategy across socio-demographic groups is an imminent and crucial public policy challenge given that (1) eventual will be highly constrained for at least first several months vaccination campaign, (2) there stark differences in transmission severity impacts from SARS-CoV-2 groups. Previous experience development...
Fish in all the world's oceans exhibit variable body size and growth over time, with some populations exhibiting long-term declines size. These patterns can be caused by a range of biotic, abiotic, anthropogenic factors impact productivity harvested populations. Within given species, individuals often life history strategies that may cause groups to buffered against change. One most studied size-at-age has been salmon; Chinook salmon Northeast Pacific Ocean are largest-bodied species have...
While conservation fish hatchery programs can be a valuable tool providing demographic support, they also cause domestication, risking unintended fitness consequences to both target and connected populations. When hatcheries are used over fixed amount of time, the interaction between program duration species life history might determine scale effects effectiveness mitigation measures. We develop mathematical model quantify approaches mitigate in such temporary programs. parameterize our...
Ecological systems often exhibit complex nonlinear dynamics like oscillations, chaos, and regime shifts. Universal dynamic equations have shown promise in modeling by combining known functional forms with neural networks that represent unknown relationships. However, these methods do not yet accommodate the of uncertainty common to ecological datasets. To address this limitation, we developed state-space universal differential a framework, accounting for uncertainty. We tested framework on...
