Generative modeling of topological and spatiotemporal data

Structured data are central to modern machine learning systems, but their structure creates modeling challenges that are not present in flat vectors or single images: graphs are invariant to node ordering, visual scenes combine symbolic relations with continuous geometry, and human or driving motion evolves through int...

An Embodied Archipelago: Bioarchaeology and World-Building in the Neolithic British Isles

This dissertation argues that the Neolithic of the British Isles is best understood not as the gradual adoption of farming or the diffusion of a cultural “package,” but as the rapid installation of a circulation-dependent, monumentally structured archipelagic world built through labor, movement, architecture, and the m...

Wavelength-Dependent Photoluminescence Mapping of Depth-Dependent Degradation Under Thermal Stress in Phenethylammonium Tetrafluoroborate Treated Perovskite Solar Cells

Abstract Studying real-time degradation in perovskite semiconductors remains an important challenge. Conventional methods often cannot separate interfacial and bulk processes or rely on destructive analysis. Here, we demonstrate multiwavelength excitation photoluminescence (PL) as a nondestructive approach to distingui...

LIBquiv: An open-source MATLAB class for time-domain simulation of physics-informed equivalent circuit models of lithium-ion batteries

Lithium-ion battery technology is today the most important electrical energy storage technology. Equivalent circuit models (ECMs) are widely used in battery research and development, and for diagnostics as part of battery management systems. The present article introduces LIBquiv, a MATLAB class for time-domain simulat...

A Unified Microscopic Picture of Cation and Anion Migration in MAPbI3

Abstract Passivating defects and restricting defect mobilities in halide perovskites to increase device lifetimes has become a main field of research. Modeling structure and mobility of point defects is an essential contribution to this endeavor. We employ molecular dynamics, based on neural network potentials trained...

Optimasi Segmentasi Kepala Janin Berbasis U-Net Melalui Preprocessing Citra USG

Fetal Head Circumference (HC) measurement using Ultrasound (USG) imagery is a crucial biometric parameter for estimating gestational age and monitoring fetal growth rate. However, automated interpretation is often hindered by speckle noise, low contrast, and blurred object boundaries inherent in USG images. This study...

Source Identification via Path-Wise Gradient Estimation

Abstract. In the context of PDE-constrained optimization theory, source identification problems traditionally entail particles emerging from an unknown source distribution inside a domain, moving according to a prescribed stochastic process, e.g., Brownian motion, and then exiting through the boundary of a compact doma...

A generalist model for diverse text-guided medical image synthesis

Deep learning algorithms require extensive data to achieve robust performance. However, data availability is often restricted in the medical domain due to patient privacy concerns. Synthetic data presents a possible solution to these challenges. Image generative models have found increasing use for medical applications...

Biosorption of Methylene Blue onto Fuji Apple Peel Biosorbent: Effects of Agitation Speeds and Contact Time

Methylene blue (MB) is a cationic dye found in industrial wastewater that requires effective and environmentally sustainable treatment. This study investigated Fuji apple peel (Malus domestica ‘Fuji’) as a low-cost, renewable biosorbent for MB removal, focusing on contact time and agitation speed. Batch experiments use...

Native Binary-Weight Training Outperforms Zero-Shot Sign Projection in MNIST Diffusion

Does severe failure after projecting a diffusion model to one-bit weights show that its binary representation is unusable? We test that implication, rather than propose a new quantizer, in a small MNIST residual U-Net. We compare floating-point training, zero-shot per-channel sign/scale projection of a trained model, b...

Dissolution morphologies of a disk under finite reaction rates: a conformal mapping approach

Reactive transport governs mineral dissolution in a wide range of geological and engineered systems, where the interplay between advection, diffusion, reaction kinetics and evolving geometry gives rise to complex interface morphologies. Even for simple initial shapes, dissolution under flow can produce asymmetric, time...

From Thought to Movement: Global Civic Pathways for the Human Happiness Community—The Lamp Lighters Network, Public Learning, and a Non-Coercive Theory-Practice Cycle of Diffusion

A theory does not enter social practice merely because it is internally coherent or because it has been committed to papers and books. Between conceptual formulation and public understanding, between individual acceptance and lived practice, and between local experience and cross-cultural diffusion, several mechanisms...
