Cramer-Rao Bounds for Joint RSS/DoA-Based Primary-User Localization in Cognitive Radio Networks [PDF]

, 2012
Knowledge about the location of licensed primary-users (PU) could enable several key features in cognitive radio (CR) networks including improved spatio-temporal sensing, intelligent location-aware routing, as well as aiding spectrum policy enforcement ...

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 ...

Spatial time-frequency distribution of cross term-based direction-of-arrival estimation for weak non-stationary signal

EURASIP Journal on Wireless Communications and Networking, 2019
In the radar array signal processing direction of arrival (DOA), the estimation of weak non-stationary signal is an important and difficult problem when both strong and weak signals are coexisting particularly because the weak non-stationary signals are ...

Source bearing and steering-vector estimation using partially calibrated arrays [PDF]

, 2009
The problem of source direction-of-arrival (DOA) estimation using a sensor array is addressed, where some of the sensors are perfectly calibrated, while others are uncalibrated. An algorithm is proposed for estimating the source directions in addition to

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 ...

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.

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.

Evaluation of Genetics in the Association Between Cardiorespiratory Fitness and Health

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT We evaluated how much cardiorespiratory fitness (CRF)‐related genetics contribute to the risk of common noncommunicable diseases (NCDs) and mortality, and whether individuals with different levels of CRF and genetic predispositions differ in health characteristics.
