Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, Volume 4, Issue 2, June 2026.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Tidal Inundation Decreases Carbon Dioxide Exchange in an Irish Atlantic Saltmarsh

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Despite the growing interest in carbon cycling in tidal‐wetland ecosystems we lack sufficient understanding of the degree to which saltmarsh ecosystems sequester carbon and the ecosystem dynamics of carbon dioxide (CO2) exchange, especially with tidal influence.

Reconstructing Digital Elevation Models From Single Synthetic Aperture Radar Images

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Traditional radar‐based methods of generating topography involve complex dual‐antenna or formation‐flying satellite configurations, interferometric processing, and specialized expertise. We present an approach for reconstructing digital elevation models (DEMs) from single Synthetic Aperture Radar (SAR) images using deep learning.

Incorporating Nitrifier‐Denitrification Improves Simulation of Nitrous Oxide and Nitric Oxide Emissions Under Intensive Nitrogen Application

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract Nitrous oxide (N2O) and nitric oxide (NO) are key components of global biogeochemical nitrogen (N) cycle, contributing to global warming and atmospheric degradation. Process‐based models have been developed and applied to quantify N2O and NO fluxes from croplands.

THE DISCRETE RADON TRANSFORM WITH APPLICATIONS TO TIME DOMAIN BEAMFORMING

, 1986
Performing a discrete Radon transform (DRT) with an array of space-time samples results in a function of slowness (inverse velocity) and time intercept.

Circulant theory of the Radon transform

, 2017
This thesis presents original work on the construction of a Circulant Theory of the Radon Transform (RT). The RT allows one to determine or reconstruct the internal structure of an object from its "projected" views.

Information Flow in Geophysical Systems

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 6, June 2026.
Abstract We present a new framework for analyzing the evolution of information in geophysical systems. Understanding how information, and its counterpart, uncertainty, propagates is central to predictability studies and has significant implications for applications such as forecast uncertainty quantification and risk management. It also offers valuable

New Heuristics for Stable LDA Parameter Search

Computational Intelligence, Volume 42, Issue 3, June 2026.
ABSTRACT The Latent Dirichlet Allocation (LDA) algorithm automatically extracts latent topics from a textual corpus, but configuring its parameters can be difficult and time‐consuming. Optimization algorithms can help determine the best parameters, but not necessarily the optimal ones.
