An Empirical Study Of Artifacts And Security Risks In The Pre-Trained Model Supply Chain, Wenxin Jiang, Nicholas Synovic, Rohan Sethi, Aryan Indarapu, Matt Hyattt, Taylor R. Schorlemmer, George K. Thiruvathukal, James C. Davis

Computer Science: Faculty Publications and Other Works

Deep neural networks achieve state-of-the-art performance on many tasks, but require increasingly complex architectures and costly training procedures. Engineers can reduce costs by reusing a pre-trained model (PTM) and fine-tuning it for their own tasks. To facilitate software reuse, engineers collaborate around model hubs, collections of PTMs and datasets organized by problem domain. Although model hubs are now comparable in popularity and size to other software ecosystems, the associated PTM supply chain has not yet been examined from a software engineering perspective.

We present an empirical study of artifacts and security features in 8 model hubs. We indicate the potential …

Devils: Cosmic Evolution Of Sed-Derived Metallicities And Their Connection To Star Formation Histories, Jessica E. Thorne, Aaron S G Robotham, Sabine Bellstedt, Luke J M Davies, Robin H W Cook, Luca Cortese, Benne Holwerda, Steven Phillipps, Malgorzata Siudek

Faculty and Staff Scholarship

Gas-phase metallicities of galaxies are typically measured through auroral or nebular emission lines, but metallicity also leaves an imprint on the overall spectral energy distribution (SED) of a galaxy and can be estimated through SED fitting. We use the PROSPECT SED fitting code with a flexible parametric star formation history and an evolving metallicity history to self-consistently measure metallicities, stellar mass, and other galaxy properties for 90 000 galaxies from the Deep Extragalactic VIsible Legacy Survey (DEVILS) and Galaxy and Mass Assembly (GAMA) survey. We use these to trace the evolution of the mass–metallicity relation (MZR) and show that the …

Misfit-Generated Structural And Optical Anisotropies Of The Natural Mos2-Pbs Van Der Waals Heterostructure Merelaniite, Luca Bindi, Arindam Dasgupta, Pinaki Mukherjee, Jie Gao, Xiaodong Yang, John Jaszczak

Michigan Tech Publications, Part 1

Significant efforts developing MoS2-PbS-based heterostructure devices with several different architectures show promise for photosensor, solar cell, and chemical sensor applications. Merelaniite (Mo4Pb4VSbS15) is a newly discovered natural van der Waals heterostructure of the cylindrite type, composed predominantly of heavily modulated pseudotetragonal PbS layers and pseudohexagonal MoS2 layers with large misfit-induced anisotropy. For an incommensurate modulated structure, the refined structural model from single-crystal x-ray diffraction analysis is in reasonable agreement with the results obtained by high-resolution scanning transmission electron microscopy, especially in light of the fact that that the two isolated single-crystal domains used for the x-ray and electron diffraction experiments …

Microbiome Diversity And Metabolic Capacity Determines The Trophic Ecology Of The Holobiont In Caribbean Sponges, Michael P. Lesser, M. Sabrina Pankey, Marc Slattery, Keir J. Macartney, Deborah J. Gochfeld

School of Earth, Environmental, & Marine Sciences Faculty Publications

Sponges are increasingly recognized as an ecologically important taxon on coral reefs, representing significant biomass and biodiversity where sponges have replaced scleractinian corals. Most sponge species can be divided into two symbiotic states based on symbiont community structure and abundance (i.e., the microbiome), and are characterized as high microbial abundance (HMA) or low microbial abundance (LMA) sponges. Across the Caribbean, sponge species of the HMA or LMA symbiotic states differ in metabolic capacity, as well as their trophic ecology. A metagenetic analysis of symbiont 16 S rRNA and metagenomes showed that HMA sponge microbiomes are more functionally diverse than LMA …

Core-Collapse Supernova Constraint On The Origin Of Sterile Neutrino Dark Matter Via Neutrino Self-Interactions, Yu-Ming Chen, Manibrata Sen, Walter Tangarife, Douglas Tuckler, Yue Zhang

Physics: Faculty Publications and Other Works

Novel neutrino self-interaction can open up viable parameter space for the relic abundance of sterile-neutrino dark matter (SvDM). In this work, we constrain the relic target using core-collapse supernova which features the same fundamental process and a similar environment to the early universe era when SvDM is dominantly produced. We present a detailed calculation of the effects of a massive scalar mediated neutrino self-interaction on the supernova cooling rate, including the derivation of the thermal potential in the presence of non-zero chemical potentials from plasma species. Our results demonstrate that the supernova cooling argument can cover …

Using Gis-Based Land Use Strategies To Minimize The Impacts Of Urbanization On Agricultural Land And Forest Cover: Case Study Of The City Of Limbe, Cameroon, Lucy Ebude Deba Enomah

USF Tampa Graduate Theses and Dissertations

Urbanization is one of the most dominant phenomena of the 21st century; it is propelled by natural growth and rural-to-urban migration. This latter is typically a product of rural residents moving to urban centres in search of economic opportunities. This phenomenon is accompanied by immense land use and cover changes – predominantly agricultural and forest lands to urban land uses such as buildings and infrastructure. The goal of this research was to contribute to efforts to minimize the impacts of urbanization on agricultural land and forest cover in Limbe, Cameroon, and to develop GIS-based strategies to allocate suitable land for …
