All Works

To develop a robust, scalable vision-based model for automatic detection and quantification of dust accumulation on solar photovoltaic panels, overcoming limitations of existing convolutional and attention-based methods and supporting proactive maintenance. We propose DustMambaNet, a hybrid model that consists of a pretrained InceptionV3 convolutional neural network as a feature extractor and two selective state space sequence modules. The state space modules use gated depthwise convolutions to represent long-range spatial dependencies that are of linear complexity, after rearranging spatial features to form sequences. The network provides a binary classification of dust with a severity index (DSI) and a continuous one. All …

The Timing Of Albedo Declines With Reforestation, Christopher A. Williams, Surendra Shrestha, Susan Cook-Patton, Natalia Hasler, Drew E. Terasaki-Hart, Samantha Yeo

Geography

Reforestation is a leading climate solution for removing carbon dioxide from the atmosphere, but generally decreases surface albedo, which diminishes its climate mitigation value. Knowing how quickly this albedo effect unfolds relative to carbon removal is critical for planning climate mitigation actions, yet the temporal changes in albedo are poorly described. This study uses satellite observations to characterize temporal changes in albedo with stand development for different forest types and ecoclimatic settings around the world. We find that about half of the climate warming effect from decreased albedo occurs within 40 years, but that it takes anywhere from 50 to …

Investigating The Role Of Striatal Cholinergic Interneuron D2 Receptors In Behavioral Flexibility, Janyn J. Alfred

Dissertations, Theses, and Capstone Projects

Dopamine (DA) and acetylcholine (ACh) interact within the striatum to shape reward-based learning and choice behavior. DA D2 receptors on cholinergic interneurons (CIN D2Rs) were genetically knocked out to investigate their role in choice allocation using a two-lever matching paradigm. Behaviorally, both knockout (KO) and wild-type (WT) mice learned the initial task equally well. When shifted to asymmetric matching schedules (VI-90 vs. VI-180), ideal matching predicts that mice should allocate exactly 67% of their total responses to the rich lever. Neither group matched as predicted by the matching law. Instead, the KO mice showed a pattern where the higher rate …

Nāgasvaram Ensemble Music In Contemporary South India: Perspectives Of Revival, Rajeswari Ranganathan

Dissertations, Theses, and Capstone Projects

This dissertation is a study of nāgasvaram ensemble music in South India based on ethnographic research in Tamil Nadu conducted between 2022 and 2026. Drawing from observations of its various performance contexts and extensive interviews with contemporary practitioners, teachers, students, impresarios, and archivists, this study examines how the aesthetics, social contexts, and circulation of nāgasvaram ensemble music have evolved over the last four decades. Countering prevalent narratives of its decline and highlighting its endurance, I argue that this musical practice is undergoing a revival, both shaped by and contributing to ongoing social transformations.

Theoretical Analysis And Performance Interpretation In Thomas Adès’S Traced Overhead, Han Chen

Dissertations, Theses, and Capstone Projects

While many post-tonal composers avoid any inkling of tonality by embracing dissonance or breaking tonal resolutions, Thomas Adès does not shy away from the traditional harmonies that strongly relate to tonal music, such as the circle of fifths, major and minor triads, and the horn-call motif, but adopts several intervallic systems that govern all the notes, including aligned cycles, parsimonious voice leading, and the twelve-tone aggregate.

To examine how Adès uses these intervallic systems to repurpose traditional harmonies, this dissertation presents a close tonal analysis of his solo piano work Traced Overhead. Integrating historical, pianistic, and extramusical contexts, this …

Loss Of Function Dnmt3a Mutation Leads To Aberrant Neutrophil Migration, Frieda Zimmer, Daniel E Kennedy, Spencer L Redding, Ruoqiong Cao, Sarah M Waldvogel, Apoorva Thatavarty, Bryan Bahoua, Brandon T Tran, Arushana A Maknojia, Margaret A Goodell, Antony Rodriguez, Katie A Matatall, Katherine Y King

Faculty, Staff and Students Publications

Clonal hematopoiesis (CH), an age-related expansion of somatically mutated hematopoietic clones, is associated with increased risk of severe infections including coronavirus disease (COVID)-19, yet the underlying mechanisms remain unclear. Here, we investigated the impact of Dnmt3a deficiency in a murine model of influenza A virus (IAV) pneumonia. Dnmt3a-deficient mice exhibited increased pulmonary viral burden and reduced neutrophil accumulation in IAV-infected lungs despite comparable circulating neutrophil numbers. Functional analyses of neutrophils showed impaired chemotactic migration in vitro, whereas maturation, antimicrobial enzyme content, and metabolic capacity were unchanged. Transcriptomic profiling revealed downregulation of pathways involved in chemotaxis, cytokine signaling, and cellular activation, …

Think Twice Before You Sign! An Experiment On A Cautionary Function Of Contractual Formalities, Monika Leszczynska

Faculty Scholarship

Contractual formalities, such as handwritten signatures, have long been viewed as serving a cautionary function that protects individuals from entering ill-considered agreements. With the rise of digital contracting, it is uncertain whether online forms of assent can play the same role. In an incentivized laboratory experiment, four modes of contract confirmation were compared: clicking “OK,” typing one’s name, entering a PIN code (analogous to a qualified e-signature), and handwritten signing. The study examined how these methods affect choices between smaller–sooner and larger–later rewards. Results show that participants were more impulsive when confirming by clicking “OK” or typing their name than …

Soil Microbial Recovery From A Pulse Disturbance Following A Press Disturbance, Gretchen Bahmueller

Master's Theses and Capstones

Though a natural phenomenon, disturbance events like drought and freeze-thaw cycles are increasing in frequency and severity due to climate change. At the forefront of these disturbances are soil microorganisms, which provide essential ecosystem services like carbon and nitrogen cycling. Previous work has reported responses of microbial communities to either a long-term press disturbance or a short-term pulse disturbance, with few studies examining how these disturbance types interact to influence microbial activity. This work sought to understand how soil microorganisms recover from a one month-long simulated moisture or freezing disturbance after experiencing 30+ years of soil warming. Heated and control …

Using The Plasma Dose-Response Technique To Determine The Bioavailability Of Commercial Rumen-Protected Amino Acids, Tessa Mae Baillargeon

Master's Theses and Capstones

There continues to be gaps in comparing the bioavailability of different rumen-protected methionine and lysine products. Many techniques have been developed to analyze these products with in vivo techniques considered the gold standard. The following three studies were proposed to determine the relative bioavailability value of products containing lysine and various forms of methionine using the plasma dose-response method as described by Whitehouse et al., 2017. Trial one compared two levels (18 g/d and 36 g/d) of L-Met infusion and fed LipoActiv L-Met 60. Trial two compared infusions of, and products containing, DL-Met and HMTBa (2-hydroxy-4-(methylthio)butanoic acid). Trial three used …

Understanding The Functionality Of Tuberculate Ectomycorrhiza Of Quercus Species Within The Context Of Soil Warming, Andre David Chiang

Master's Theses and Capstones

Tuberculate ectomycorrhizae (TECM) of oak are understudied, morphologically unique ectomycorrhizal (ECM) fungal structures whose initial observation at the Harvard Forest long-term ecological research site (Petersham, MA) were confined strictly to warmed plots. This study provided the first quantification of oak-associated TECM under experimental warming, characterizing their lifecycle and ecological role. We quantified and characterized TECM over three sampling periods during the growing season (May, June, August) of 2025 at two soil warming experiments at Harvard Forest: Barre Woods and Prospect Hill. We also identified the fungi associated with TECM structures, along with sclerotia found in the same samples. We quantified …

High Spatiotemporal Snow Cover Mapping With Multiscale Observations In A Transitional Montane Forest, Rashik Raj Koirala

Master's Theses and Capstones

Accurate estimation of fractional snow-covered area (fSCA) in forested areas is critical for understanding snowmelt dynamics and meltwater inputs to streams, yet snow cover mapping in forested areas is still challenging using ground-based and satellite-based snow observations. This thesis develops and evaluates multi-scale approaches for monitoring fSCA using field cameras, upscales it to watershed scale using unoccupied aerial systems (UAS), and develops a framework to extract snow cover in forests using Sentinel-2 satellite imagery in mixed deciduous and coniferous forests of New Hampshire, USA.

In the first study, machine learning classifiers’ ability to extract fSCA from field camera RGB imagery …

Linking Vegetation Phenology To Dissolved Organic Matter Wet Deposition, Paola Miramontes Gonzalez

Master's Theses and Capstones

Atmospheric wet deposition delivers important inputs of organic and inorganic compounds to ecosystems, yet the drivers of dissolved organic matter variability in wet deposition remain poorly understood. Dissolved organic matter (DOM), composed of dissolved organic carbon (DOC) and dissolved organic nitrogen (DON), can make up a substantial fraction of total carbon and nitrogen delivered through wet deposition and may play a role in shaping ecosystem nutrient inputs. Although vegetation emissions have been hypothesized as drivers of DOM wet deposition due to increased concentrations of DOC and DON during the growing season, no study has directly evaluated whether metrics of vegetative …

Coming Soon To A Cellar Near You: Novel Range Expansion Of A Short-Bodied Cellar Spider, Physocyclus Enaulus (Araneae: Pholcidae), In A Building In Central Illinois, Usa, Ricky Gieser, Mark Davis

The Great Lakes Entomologist

A reproductive population of Physocyclus enaulus Crosby, 1926 (Pholcidae: Araneae), a short-bodied cellar spider native to the American southwest and Mexico, is documented for the first time in a single building in Illinois, far outside of their known native range. The means of introduction is unknown but is likely influenced by either accidental hitchhiking spiders or a deliberate introduction to control brown recluse populations. Cellar spiders were purchased and released in the same building to predate on brown recluse spiders, but the first P. enaulus individual was found a year prior to the release. These cellar spiders have a wide-ranging …

The Great Lakes Entomologist

We report the first record of the rare water boatman, Palmacorixa janeae Brooks (Hemiptera: Corixidae), from the United States. Two hundred and forty specimens were collected in Wisconsin from Chequamegon Bay in Lake Superior. Palmacorixa gillettei Abbott, a similar species known from the area, was also identified among the samples. Most specimens, all of which were adults, were collected at night using a neuston net towed along the surface for approximately 5 minutes. The adults were found in areas that were 34 meters to 4.2 kilometers from the shore that had depths ranging from 1.0 to 5.5 meters. All representatives …

Seasonal Emergence, Egg Gallery Characteristics, And Natural Enemies Of The Eastern Ash Bark Beetle, Hylesinus Aculeatus (Coleoptera: Curculionidae: Scolytinae), In Michigan, Robert A. Haack

The Great Lakes Entomologist

Hylesinus aculeatus Say (Coleoptera: Curculionidae: Scolytinae) commonly infests the trunks and limbs of recently dead, dying, or cut ash (Fraxinus spp.) trees in eastern North America. In the Great Lakes region, H. aculeatus is univoltine, overwinters as adults, breeds in late spring and early summer, and constructs transverse biramous egg galleries. I sampled trunk and branch sections from three small-diameter white ash (F. americana L.) trees that were cut in April 1986 in Ingham County, Michigan, and then naturally infested by H. aculeatus and associates. Bolts cut from these trees and placed in an outdoor rearing cage in …

Phenology Of Ground-Dwelling Beetle Assemblages (Coleoptera: Carabidae, Staphylinidae) From Three Fir Stands Of Southern Québec (Canada), With Comparison Among Selected Species Between 1985 And 2006-2010, Claire Levesque, Gilles-Yvon Levesque

The Great Lakes Entomologist

A total of 5,303 adult epigaeic beetles (Coleoptera) were collected using pitfall traps across three balsam fir (Abies balsamea (Linnaeus) Miller) stands in southern Québec (Canada). Sampling occurred during May–September 1985 in sites representing three distinct understory vegetation types. Three dominant families (Carabidae, Leiodidae and Staphylinidae) together represented at least 93% of catches at each site. Staphylinidae were less abundant than Carabidae at two sites, whereas Carabidae and Staphylinidae were collected in similar numbers at a third stand. Associated with increased abundance and heterogeneity of the understory vegetation, we observed 1) the decrease of specialist forest carabids, often active …

Caddisfly (Trichoptera) Assemblages From The Southern Laurentian Highlands, Québec (Canada), David C. Houghton

The Great Lakes Entomologist

The caddisflies (Trichoptera) represent an important taxon for the natural functioning of aquatic ecosystems and as biological monitoring organisms; however, basic information on their assemblages is still lacking in Canada. In this study, adult caddisflies from 30 lakes and streams in the southern Laurentian Highlands of Québec were sampled during 2023–2025. A total of 186 caddisfly species were determined, including 22 species not previously reported from Québec and eight not previously reported from anywhere in Canada. Two species of Cernotina also represented the first collection of that genus within the province. Using Indicator Species Analysis, six species indicated small rivers, …

Paper Wasp Species Polistes Fuscatus (Hymenoptera: Vespidae) Tracks Urban Lead (Pb) Levels More Than Polistes Dominula, Lindsey R. Kemmerling, Anna L. Lovat, Allison A. Hanka, Emilie C. Snell-Rood

The Great Lakes Entomologist

Lead (Pb) is a persistent, toxic pollutant with widespread but inequitably distributed impacts, especially for humans in urban areas. The impacts of lead pollution on other organisms is largely unknown, even as they commonly experience exposure to lead alongside humans. We tested hypotheses regarding the lead concentrations of paper wasps across a gradient of pollution relative to soil and human lead levels, and correlations with wasp body condition. We collected two species of paper wasp across an urban gradient of lead pollution: Polistes fuscatus (Fabricius) (Hymenoptera: Vespidae), native to our study location, and Polistes dominula (Christ), nonnative to our study …

Long-Term Monitoring And Response Of Papaipema Sciata Bird (Lepidoptera: Noctuidae) To Prescribed Fire In Michigan (Usa), Gregory J. Norwood, Logan M. Rowe, Brett A. Degregorio, David L. Cuthrell, Aaron D. Meredith, Steven M. Gray

The Great Lakes Entomologist

The Culver’s root borer moth (Papaipema sciata) (Lepidoptera: Noctuidae) is a rare Noctuid that requires Culver’s root (Veronicastrum virginicum) to complete its lifecycle within remnant native grasslands and open woodlands in the midwest and northeast United States. We report on 26 years of monitoring this species’ colonization of Culver’s root stems at Algonac State Park (ASP) in Michigan, where prairies have been maintained by prescribed fire since 1990. P. sciata is considered fire sensitive because eggs spend the dormant season in the combustible prairie litter and duff near host plants. The objectives were to determine the …

Could The European Thanasimus Formicarius Outcompete The North American Thanasimus Dubius (Coleoptera: Cleridae) If Introduced To North America?, Robert A. Haack, Robert K. Lawrence

The Great Lakes Entomologist

A federal quarantine was enacted in the United States (US) in the fall of 1992 in response to discovery of the Eurasian pine shoot beetle, Tomicus piniperda (L.) (Coleoptera: Scolytinae), in July 1992 in Ohio. The quarantine regulated movement of pine products (e.g., Christmas trees, nursery stock, and logs) at the county level from infested to uninfested US states. A classical biological program was considered for T. piniperda starting in 1995, focusing on the Eurasian clerid beetle Thanasimus formicarius (L.), an important predator of T. piniperda. Concerns were raised in 1996 that if T. formicarius were released in the …
