Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract India often faces challenges in monitoring atmospheric carbon dioxide (CO2) through satellite observations due to persistent cloud cover, especially during the monsoon season. This limitation affects the continuous tracking of carbon and hinders accurate assessments of carbon‐climate interactions.

A DOA estimation algorithm based on equalization-cancellation theory [PDF]
, 2010 Direction of arrival (DOA) estimation plays an important role in multi-channel (binaural) speech enhancement systems and auditory humanoid robots. A number of localization methods have been presented, however, most of them require a large array of ...

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Accurately predicting the atmospheric dispersion of volcanic ash and gases is crucial for both scientific understanding and hazard mitigation. Estimating Eruption Source Parameters (ESP), such as mass eruption rate, plume height, duration, and particle size distribution and properties, remains challenging due to the complex nature of volcanic ...

Evaluating TEMPO Formaldehyde Retrievals With Co‐Located Ground‐Based FTIR and Pandora Observations
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.Abstract Formaldehyde (HCHO) is an important proxy for volatile organic compounds and photochemical activity, with significant implications for air quality and atmospheric chemistry. The recently launched geostationary satellite instrument Tropospheric Emissions: Monitoring of Pollution (TEMPO) provides the first‐ever hourly observations of HCHO and ...

Enhanced off-grid DOA estimation by corrected power Bayesian inference using difference coarray
The Journal of Engineering, 2019 Sparse Bayesian inference for on-grid direction-of-arrival (DOA) estimation using difference coarray was investigated in the authors’ previous work to estimate more signal sources than the number of physical antenna elements. Sparse Bayesian inference is

Neural Network–Assisted Metasurface Retroreflector With Wide‐Angle Adaptivity
Electron, Volume 4, Issue 2, May 2026.This work proposes a wide‐angle, multi‐polarization, self‐sensing, and self‐adaptive intelligent metasurface retroreflector, with a planar profile and ultrathin thickness. By integrating a pre‐trained artificial neural network (ANN), the metasurface retroreflector can recognize the incident angle and promptly adapt to changes in the incoming wave.

A combined BP‐MF algorithm for wideband off‐grid DOA estimation with DP prior
Electronics Letters, 2022 Direction‐of‐arrival (DOA) estimation based on sparse Bayesian learning (SBL) framework has attracted extensive attention. The accuracy of on‐grid DOA estimation is restricted by the prescribed grid, while off‐grid approaches resolves the problem of grid

Cerebral Hemodynamic Changes During Cardiac Surgery: A Feasibility MR Study in Piglets
NMR in Biomedicine, Volume 39, Issue 5, May 2026.Congenital heart disease surgery in infants requires cardiopulmonary bypass (CPB), which increases the risk of brain injury. Conventional heart‐lung machines (HLMs) cannot operate inside MRI scanners, limiting real‐time assessment of cerebral changes. We developed an MR‐conditional HLM and tested it in piglets during CPB.
