Monitoring and assessment for obstructive sleep apnea

open access: yesFlexMat, EarlyView.
This review systematically classifies Obstructive Sleep Apnea (OSA) monitoring indicators into three categories: physical, biochemical, and electrophysiological indicators, and lists several methods for each category. Abstract Obstructive sleep apnea (OSA) is a common chronic sleep‐disordered breathing disease characterized by recurrent upper airway ...

How Thunderstorms Are Changing in Mexico: Trends and Characteristics

open access: yesInternational Journal of Climatology, EarlyView.
Thunderstorm days in Mexico have increased significantly since 1992, with pronounced regional and seasonal contrasts. Increasing moisture emerges as the most spatially coherent environmental signal. At the same time, enhanced instability characterizes northeastern and central Mexico, revealing distinct regional controls on thunderstorm activity and ...

Urban traffic congestion alleviation system based on millimeter wave radar and improved probabilistic neural network

open access: yesIET Radar, Sonar & Navigation
The millimeter‐wave radar sensor is widely used for urban traffic surveillance because of its weather resistance and high detection accuracy. Methods such as fuzzy theory, pattern recognition, and artificial neural networks have been integrated into the ...

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems

open access: yesLaser &Photonics Reviews, EarlyView.
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Geophysical investigation at Sainte‐Marguerite‐sur‐Mer (Normandy, France): From a supposed landfill to a forgotten military network?

open access: yesNear Surface Geophysics, EarlyView.
Abstract This study focuses on characterising a strong and unexpected anomaly observed during an electromagnetic induction (EMI) survey conducted on the chalk cliff plateau at Sainte‐Marguerite‐sur‐Mer, in the Normandy region, France. The site was selected for a long‐term study of chalk cliff coastal erosion that began in 2017 and has been studied for ...

Automatic insect identification, counting, and monitoring techniques: a review

open access: yesPest Management Science, EarlyView.
Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...

Modeling rainfall drop size distribution moments using an S‐band polarimetric radar in complex terrain

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Using S‐band dual‐polarization radar and disdrometers during PRECIP 2022 in Taiwan, we analyze a Mei‐Yu frontal event with widespread stratiform rain and embedded convection. Multiple disdrometers are used to create a novel drop size distribution model for S‐band radars resolving both the drizzle and precipitation modes. The model reveals both inferred

The benefit of neighborhood methods for the assimilation of cloud‐affected radiances evaluated in observing‐system simulation experiments

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Neighborhood methods are commonly used in verification to avoid the double‐penalty issue. This study evaluates such methods for the assimilation of infrared and visible satellite observations and extends them to multiscale assimilation. Moreover, a novel technique is tested aimed at mitigating complex biases and structural errors in real‐world model ...

Characteristics of quasi‐stationary band‐shaped precipitation systems in Japan between 1989 and 2022

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
(a) Annual occurrence frequency of QBPSs (green bars), five‐years moving average (blue line), and regression trend (red line) for 1989–2022. (b) Distribution of the geographical occurrence frequencies of QBPSs with a 5‐km resolution for 1989–2022. Quasi‐stationary band‐shaped precipitation systems (QBPSs) are a major cause of localized heavy rainfall ...
