Towards Graph Foundation Models: Learning Generalities Across Graphs Via Task-Trees

Defensive Publications Series

Foundation models aim to create general, cross-task, and cross-domain machine learning models by pretraining on large-scale datasets to capture shared patterns or concepts (generalities), such as contours, colors, textures, and edges in images, or tokens, words, and sentences in text. However, discovering generalities across graphs remains challenging, which has hindered the development of graph foundation models. To tackle this challenge, in this paper, we propose a novel approach to learn generalities across graphs via task-trees. Specifically, we first define the basic learning instances in graphs as task-trees and assume that the generalities shared across graphs are, at least partially, preserved …

The Significance Of Cannibalism, Panic, And Sanctuary In The Interactions Between Prey And Predator With A Stage Structure, Ahmed Sami Abdulghafour, Raid Kamel Naji

Iraqi Journal for Computer Science and Mathematics

This paper analyzes a novel prey-predator model that takes into account the predator's stage structure, cannibalism within the predator population, panicky behavior, and the existence of a sanctuary where the prey might hide from the predator. The Holling type II functional response is used in the predation process. The behavior of the identified fixed points of the proposed system has been closely analyzed. The analysis focuses on the local stability and potential bifurcations that could happen close to the system's fixed points. The Lyapunov function approach is used to investigate the fixed-point stability zone globally. Numerical simulations were run to …

Soil Biogeography And Community Assembly In Polar Regions, Jesse Jorna

Theses and Dissertations

The polar regions provide community ecologists with natural microcosms, that include reduced species diversity, steep environmental gradients and limited human perturbance. Soil biodiversity in the polar regions is poorly understood, and the driving forces behind community compositions can range in scale from glacial forces 20,000 years ago to the impact of a researcher's footstep. Here, we present the results of an investigation of the driving factors behind biodiversity in Arctic and Antarctic soils, with specific attention to the role of community assembly processes. We suggest a framework for investigating the effects of inter-bacterial community processes like facilitation and argue for …

Multi-Scale Thermal Mapping Of Submarine Groundwater Discharge In Coastal Ecosystems Of A Volcanic Area, Ebony L. Williams, Christopher B. Kratt, Raymond S. Rodolfo, Mark R. Lapus, Ryan R. Lardizabal, Aya S. Bangun, Amber T. Nguyen, Scott W. Tyler, M. Bayani Cardenas

Environmental Science Faculty Publications

Submarine groundwater discharge (SGD) in volcanic areas commonly exhibits high temperatures, concentrations of metals and CO2, and acidity, all of which could affect sensitive coastal ecosystems. Identifying and quantifying volcanic SGD is crucial yet challenging because the SGD might be both discrete, through fractured volcanic rock, and diffuse. At a volcanic area in the Philippines, the novel combination of satellite and drone-based thermal infrared remote sensing, ground-based fiber-optic distributed temperature sensing, and in situ thermal profiling in coastal sediment identified the multi-scale nature of SGD and quantified fluxes. We identified SGD across ∼30 km of coastline. The different approaches revealed …

Exploring The Efficacy And Limitations Of Histogram-Based Fake Image Detection, Dirk Hölscher, Christoph Reich, Frank Gut, Martin Knahl, Nathan Clarke

School of Engineering, Computing and Mathematics

Generative image models pose challenges to image authenticity and trustworthiness, blurring the line between real and fake content. This paper addresses these concerns by proposing a histogram-based approach using pre-trained models (vgg16, ResNet50, Xception) to train classification networks for distinguishing real from generated images. Leveraging histograms derived from images, the method aims to accurately classify images as authentic or synthetic. Through experiments, the paper examines the effectiveness of the approach in mitigating the risks associated with fake contents widespread dissemination. Results demonstrate promising advancements in detecting image manipulation and preserving the integrity of visual information amidst the spread of generative …

Journal of Electrochemistry

Single-entity collisional electrochemistry (SECE) is a branch of single-entity electrochemistry. It can directly characterize entities/particles with single particle resolution through random collisions between particles and electrodes in a solution, and obtain rich physicochemical information, thus becoming one of the frontiers of electroanalytical chemistry in the past two decades. Interestingly, the (micro/nanoscale) sensing electrodes have evolved from a polarizable liquid/ liquid (mercury/liquid) interface to a solid/liquid interface and then to a liquid/liquid interface (i.e., an interface between two immiscible electrolyte solutions, ITIES), as if they have completed a cycle (but in fact they have not). ITIES has become the latest sensing …

Aqueous Supercapacitors With Wide Operative Voltage Window And Long Cycling Life Enabled By Electrolyte Hybridization Effect, Shi-Hua Ma, Qi Yin, Jin-Ping Zhao

Journal of Electrochemistry

Developing supercapacitors (SCs) with long cycling life and wide operative voltage window is a significant topic in the field of aqueous electrolytes. Although the design of water in salt (WIS) electrolytes has pushed the development of aqueous electrolytes to a new height, the WIS electrolytes with an operative voltage window of up to 2.5 V is still very scarce. Herein, in order to enrich the type of aqueous electrolyte with high operative voltage, tetramethylammonium trifluoromethanesulfonate (TMAOTf) based WIS electrolyte was used as a model to construct WIS based hybrid electrolyte with acetonitrile (ACN) co-solvent and LiTFSI co-solute. In view of …

Vandergrift, Kuo-Pin Tseng, Nurun Nahar Lata, Will Kew, Kaitlyn Suski, Johannes Weis, Gourihar Kulkarni, Larry K. Berg, Jerome D. Fast, Libor Kovarik, Lynn Mazzoleni, Alla Zelenyuk, Swarup China

Michigan Tech Publications

Wildfires emit solid-state strongly absorptive brown carbon (solid S-BrC, commonly known as tar ball), critical to Earth's radiation budget and climate, but their highly variable light absorption properties are typically not accounted for in climate models. Here, we show that from a Pacific Northwest wildfire, over 90% of particles are solid S-BrC with a mean refractive index of 1.49 + 0.056i at 550 nm. Model sensitivity studies show refractive index variation can cause a ~200% difference in regional absorption aerosol optical depth. We show that ~50% of solid S-BrC particles from this sample uptake water above 97% relative humidity. We …

Development Of Novel Nanobiocatalysts For Enhancing Carbon Dioxide Capture, Merna Tarek Farag

Thesis/ Dissertation Defenses

The emissions of greenhouse gases to the atmosphere cause a climate change that has devastating impacts. Therefore, reaching the net zero goal, which is the balance between the amount of greenhouse gas emitted to the atmosphere and that removed from it, is critical for the future of our planet unless the net-zero goal is achieved soon, the impacts of climate change will continue to worsen, with severe consequences for ecosystems, human health, and global security. Achieving this goal requires a fundamental shift in the way we produce and consume energy, including the rapid transition to renewable energy sources with improvements …

Enhancing Muscle Health And Modulating Immune Response With Galectin-1 In Lgmd2b/R2 Models, Stefannia Esparza Pulido

Theses and Dissertations

Limb-Girdle Muscular Dystrophy Type 2B/R2 (LGMD2B/R2) is a type of dysferlinopathy, a progressive muscle-wasting disorder caused by mutations in the dysferlin gene. Hallmarks of the disease include chronic inflammation, impaired muscle regeneration, and eventual muscle degeneration. Currently, no FDA-approved therapies are available for dysferlinopathies. Recombinant human Galectin-1 (rHsGal-1) has shown multiple roles in maintaining skeletal muscle homeostasis, promoting muscle repair, enhancing myogenesis, and modulating inflammation by downregulating the NF-κB pathway. The ability of rHsGal-1 to modulate the immune response is particularly promising for therapeutic applications in patients with LGMD2B/R2. In this study, we evaluated the effects of rHsGal-1 in a …

Evidence For Subsidence Rate Variation In The Newark Basin And Its Influence On The Deposition Of Fluvial Sediments Of The Stockton Formation, Jane L. Alexander, Sean T. Thatcher, Jay Tobon, Victoria Rivelli

Publications and Research

The Stockton Formation of the Newark Basin represents an exciting time in Earth history during the early stages of rifting of the North Atlantic, with rapid subsidence and sediment deposition. Much of the previous work on this formation has been done using drill cores, with development limiting surface exposure. While this allows us to build a full stratigraphic sequence of deposition, it has the potential to miss smaller-scale variability and sedimentary structures. It is also difficult to understand the three-dimensional geometries, architecture and relationships between the depositional elements from drill core alone. An outcrop in North Bergen, NJ that was …
