Abstract Background Out‐of‐hospital cardiac arrests (OHCAs) are an important global health burden, and risk factors for patients with dispatcher‐unrecognized OHCAs have not yet been well investigated. Objectives The purpose of this study was to evaluate the association between multiple‐ambulance dispatches and clinical outcomes in patients with ...

Adaptive Based Beamforming for Direction-of- Arrival (DOA) Estimation
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.

Performance evaluation of direction-of-arrival (DOA) estimation algorithms for mobile communication systems [PDF]
Spatial filtering for mobile communications has attracted a lot of attention over the last decade and is currently considered a very promising technique that will help future cellular networks achieve their ambitious goals. One way to accomplish this is via array signal processing with algorithms which estimate the direction-of-arrival (DOA) of the ...

Multi‐Species Constraints Resolve Methane Source Versus Sink Changes: Lessons From 2020
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

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.

Enhanced off-grid DOA estimation by corrected power Bayesian inference using difference coarray
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

Eruption Source Parameters in Volcanic Plume Modeling: Advances, Challenges, and Future Directions
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 ...
