Variability in nutrient and carbon cycling of constructed marshes

Alyssa LeClaire, Jenny Davis, Molly Bost, David De la Garza

Salt marshes provide valuable ecosystem services, including filtering nutrients and trapping sediments from the water column, but are increasingly threatened by sea-level rise and coastal development. Constructed marshes offer a potential pathway to offsetting marsh loss, but the extent to which they …

Learning from Africa's urban climate innovations: A new framework and comparative analysis to foster transformative climate action

Hayley Leck, Clara Marais, Paul Isolo Mukwaya, Michelle Koyaro et autres

African cities face intensifying climate risks shaped by rapid urbanisation, informality, unequal access to services, and exclusionary governance, yet they are also important sites of experimentation and innovation. This paper examines how climate innovations in African cities have emerged across technological, social, …

AI and blockchain adoption in the public sector: evidence on innovation capacity and institutional context

Bruna Bruno, Angelo Murano

This paper examines whether artificial intelligence (AI) and blockchain follow similar adoption dynamics in the public sector. While both technologies are associated with digital transformation, their diffusion may depend on technological, economic, and institutional conditions.Using an inventory of public-sector technology innovation initiatives …

How clean is clean? S and T challenges and perspectives on surface contamination detection and decontamination verification

Conor H. Sharp, Phillip Wilcox, Nicole M. Murphy

After an attack in which chemical or biological weapons are employed, thorough equipment decontamination is critical to ensure that materiel (tanks, trucks, planes, etc.) can be quickly returned to service without the residual risk of agent exposure to the Warfighter and environment. …

A comparative analysis of UAV computer vision systems in physically realizable adversarial AI scenarios

Jennifer A. Csicsery-Ronay, Audrey Aldridge, Tyler Errico, Christopher Honaker et autres

Computer vision systems with object recognition are seeing broad adoption in uncrewed aircraft systems for aided target recognition. One operationally relevant implementation pairs electro-optical cameras with computer vision models to recognize camouflage patterns worn by soldiers, enabling friend-versus-foe identification. Adversarial camouflage patches …

The global refining disorder: The political geography of crude processing

Alexander Etkind, Georg-Henri Kaup, Ayansina Ayanlade, Gustavo Andreao

Why are refineries where they are, and what forces explain their distribution across planetary space? This article develops the concept of the Global Refining Disorder (GRD) to analyze the political geography of crude oil processing. Departing from location theory, which privileges transport-cost …

Measuring Carbon stock and accumulation rates prior to a beneficial use restoration project, Deal Island, MD, USA

Molly C. Bost, Jenny Davis, Alyssa M. LeClaire

Global climate change has inspired fervent investigation into salt marshes as blue carbon sinks and their potential role in mitigating climate change through CO 2 drawdown and long-term storage. Conservation and restoration of existing marsh complexes can preserve the valuable carbon stock …

Consistency-based Abductive Reasoning over Perceptual Errors of Multiple Pre-trained Models in Novel Environments

Mario Leiva, Noel Ngu, Joshua Shay Kricheli, Aditya Taparia et autres

The deployment of pre-trained perception models in novel environments often leads to performance degradation due to distributional shifts. Although recent artificial intelligence approaches for metacognition use logical rules to characterize and filter model errors, improving precision often comes at the cost of …

Understanding Untrained Deep Models for Inverse Problems [From the Guest Editors]: Algorithms and theory

Ismail Alkhouri, Evan Bell, Avrajit Ghosh, Shijun Liang et autres

In recent years, deep learning (DL) methods have been extensively developed for inverse imaging problems (IIPs), encompassing supervised, self-supervised, and generative approaches. Most of these methods require large numbers of labeled or unlabeled training data to learn effective models. However, in many …
