Mathematical Information Retrieval: Search and Question Answering

Mathematical information is essential for technical work, but its creation, interpretation, and search are challenging. To help address these challenges, researchers have developed multimodal search engines and mathematical question answering systems. This monograph begins with a simple framework characterizing the information tasks that people and systems perform as we work to answer math-related questions. The framework is used to organize and relate the other core topics of the monograph, including interactions between people and systems, representing math formulas in sources, and evaluation. We close by addressing some key questions and presenting directions for future work. This monograph is intended for students, instructors, and researchers interested in systems that help us find and use mathematical information.https://digitalcommons.usm.maine.edu/facbooks/1699/thumbnail.jp

Population dynamics, life history characteristics, and environmental drivers of Neomysis americana in the Damariscotta River estuary

Mysid shrimp (Neomysis americana) play a pivotal role in estuarine food webs by linking primary producers to higher trophic levels and serving as an important food source for commercially valuable fish. Despite their ecological significance, mysids are often under sampled, leading to gaps in our understanding of their population dynamics and life history traits. My study investigated N. americana over a full year (June 2023 to May 2024) in the temperate Damariscotta River Estuary in Maine. My research focused on how environmental factors such as temperature, turbidity, salinity, chlorophyll-a, and zooplankton biomass affect mysid density and reproduction. Temperature emerged as a key factor, with warmer temperatures leading to higher mysid density. My results also indicated distinct overwintering cohorts, highlighting that at least a portion of the population remains in the estuary year-round, with seasonal shifts in size distribution. These findings enhance our understanding of N. americana\u27s ecological role in temperate estuaries, building on previous research of this important species
