Design of Orthogonal Phase of Arrival Positioning Scheme Based on 5G PRS and Optimization of TOA Performance

IEEE Access
This study analyzes the performance of positioning techniques based on configuration changes of 5G New Radio (NR) signals. In 5G networks, a terminal’s position is determined from the Time of Arrival (TOA) of Positioning Reference Signals (PRS ...

Disaster Schooling Experiences and Emergent Crises: Lessons From Puerto Rico

Anthropology &Education Quarterly, Volume 57, Issue 3, September 2026.
ABSTRACT This paper examines the disaster schooling experiences of Puerto Rican educators, families, and students across multiple crises following Hurricane Maria. Drawing on 11 months of ethnographic research, we analyze how schooling unfolded across disasters and how long‐standing vulnerabilities and structural inequalities shaped responses. Findings

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

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 ...

MOCVD‐Grown MoS2 Wafers as a Transfer‐Free Platform for Top‐Gate Devices via Dry Interface Engineering

Advanced Materials, Volume 38, Issue 45, 13 August 2026.
We reveal the electronic origin of hidden interfacial doping in monolayer MoS2 grown by MOCVD, identifying sulfate related and water like species as intrinsic donors. Through dry interface engineering approach, we demonstrate MOCVD‐grown single‐crystal MoS2 wafers as a transfer‐free platform for the reliable evaluation of intrinsic gate stacks and ...

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 ...

Impact of Lactic Acid Bacteria Fermentation on the Nutritional and Sensory Quality of Arthrospira platensis Beverages

eFood, Volume 7, Issue 4, August 2026.
To improve the consumer appeal of Arthrospira platensis, this study utilized probiotic fermentation to mitigate its strong seaweed‐like aroma. Using Lactiplantibacillus plantarum significantly boosted amino acids, introduced novel volatiles, and enhanced umami flavors.

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.

A Green's Function Approach to Black Carbon: Ensembles of Policy Analysis in Southeast Asia

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Multi‐criteria decision‐making requires evaluating policies impact on multiple factors, including environmental ones, which can be a computationally prohibitive exercise. Here, we diagnose Green's functions from a chemical transport model, establishing an approach that allows users to evaluate the transport of black carbon across large ...
