A population Monte Carlo model for underwater acoustic telemetry positioning in reflective environments

Methods in Ecology and Evolution
Underwater acoustic telemetry positioning is widely used to track the fine‐scale movements of aquatic animals. In study areas near acoustically reflective surfaces, reflected transmissions may cause large detection outliers that can severely reduce the ...

A GEO‐LEO Imager Data Set for Characterizing Rapid Changes of Global Aerosol Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Aerosols, the ubiquitous small particulates in our atmosphere, have climate, air quality, and/or other impacts far from their original sources. The Dark Target Algorithm (DTA), originally developed for retrieving aerosol properties from satellite imagers in Low‐Earth Orbit (LEO), has been ported to imagers in Geostationary (GEO) orbit. Using a

MIMO-signal time-of-arrival (TOA) estimation

, 2013
Due to the large-scale implementation of MIMO (multiple input multiple output) systems (such as MIMOradar, radiomonitoring system, synchronization system) the new task of space-time coding signal (MIMO-signal) TOA estimation is being set up. Utilizing of the new signals can bring both the new possibilities for improving the accuracy of MIMO-signal TOA ...

Deforestation Triggers State‐Dependent Cloud Regimes in the Amazon

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract The Amazon's arc of deforestation is a hotspot of rapid land‐cover change. Using 20 years of MODIS imagery combined with cloud property retrievals, CERES radiative fluxes, and ERA5 data, we show that deforestation consistently enhances low‐level cloudiness over non‐forest relative to nearby forest during the Amazon dry season.

Performance comparison of time‐of‐arrival estimation techniques for LTE signals in realistic multipath propagation channels

Navigation, 2019
Long term evolution (LTE) signals have the potential to be used for positioning, especially in challenging environments such as in urban area or indoors. Among a number of positioning techniques supported by LTE, the time-of-arrival (TOA)-based technique

Position determination of acoustic source using a discrete probability density method supported by joint detection and time of arrival estimation [PDF]

Scientific Technical Review, 2017
The localization of various acoustic sources in a battlefield (such as weapon rounds, mortars, rockets, mines, improvised explosive devices, vehicle-borne improvised explosive devices and airborne vehicles) nowadays has significant history.

Characteristics of a Multi‐Model Ensemble of Mock‐Walker Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract The Radiative‐Convective Equilibrium Model Intercomparison Project (RCEMIP) phase I provided insights into the tropical radiative‐convective equilibrium state across an unprecedented ensemble of models that includes both those with parameterized and explicit convection.

Associations of Hearing Loss Defined by Updated World Health Organization Criteria With Socioeconomic Status and Health Check‐Up‐Related Factors: A Population‐Based Cross‐Sectional Study in Japan

Geriatrics &Gerontology International, Volume 26, Issue 8, August 2026.
Hearing loss (HL) was associated with lower socioeconomic status and several health check‐up–related factors, like lifestyle and examination data, especially among males. Among males, occupational noise exposure history, diabetes‐related factors, and excessive alcohol consumption showed stronger associations.

Signaling Vision: Knowing When to Quit

International Economic Review, Volume 67, Issue 3, Page 997-1013, August 2026.
ABSTRACT We study a signaling game where agents signal their type by choosing when to quit pursuing an uncertain project. High types observe news about project quality and quit when bad news arrives. Low types who do not observe any news may mimic high types by quitting continuously over a phase of time.
