Headache: The Journal of Head and Face Pain, Volume 66, Issue 7, Page 1607-1616, July/August 2026.Plain Language Summary Migraine with aura can mimic a stroke, making diagnosis difficult and sometimes leading to unnecessary treatment in the acute setting. We found that some patients with migraine with aura show characteristic changes on brain perfusion CT scans, particularly in men and those with speech symptoms, which can be better detected using ...

Adaptive Based Beamforming for Direction-of- Arrival (DOA) Estimation
CVR Journal of Science & Technology, 2015 Nowadays mobile users require increased coverage, quality of service and capacity in wireless communications. By using adaptive antennas at both transmitter and receiver in wireless communication, we can easily reach the required improvement. In this paper Adaptive Antenna plays a major role to improve the performance of wireless communication systems.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Advanced Materials, Volume 38, Issue 36, 26 June 2026.Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Parallel Complementary Virtual Arrays Algorithm for Direction of Arrival (DOA) Estimation
International Journal on Recent and Innovation Trends in Computing and Communication, 2023 This Paper discusses the challenges faced by previous method 2D Direction of Arrival (DOA) systems, such as low degrees of freedom, poor resolution, and significant estimation errors in scenarios with small snapshots. In response to these issues, the present method proposes a low-complexity 2D Direction of Arrival (DOA) estimation algorithm based on a ...

Multi‐Species Constraints Resolve Methane Source Versus Sink Changes: Lessons From 2020
Earth's Future, Volume 14, Issue 6, June 2026.Abstract Satellite observations show that atmospheric methane (CH4) increased by a record‐breaking 19 ppb in 2020, but the causes are unclear because of uncertain impacts from COVID‐related pollutant shifts on hydroxyl (OH) radical concentrations. Here we employ an ensemble of constraints to simultaneously quantify methane sources and sinks for 2020 in

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.

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 ...
