A Simplified Algorithm for Joint Real-Time Synchronization, NLoS Identification, and Multi-Agent Localization [PDF]

Real-time, high-precision localization in large-scale wireless networks faces two primary challenges: clock offsets caused by network asynchrony and non-line-of-sight (NLoS) conditions.

Unripe Banana Genotypes are Starchy Sources. Part I. Morphology, Growth Rings, and Ultrastructure of Native Starches

Starch - Stärke, Volume 78, Issue 10, October 2026.
Unripe banana flour is a starch source with a high content of resistant starch in its raw form. Recently, interest has grown in raw materials with low levels of indigestible carbohydrates. Different banana genotypes vary in granule morphology, which influences their functional properties and digestibility.

Novel high performance MIMO-OFDM based measures for NLOS identification in time-varying frequency and space selective channels

, 2012
This paper proposes new measures for non-line-ofsight (NLOS) identification in wireless localization systems. The measures are defined based on the space-time-frequency channel correlation features of multi-input multi-output (MIMO) orthogonal frequency ...

Reversible Hydration Tuning of Polar Order and Large Nonlinear Optical Response in a 2D van der Waals Crystal, LiInP2S6

Advanced Materials, Volume 38, Issue 52, 16 September 2026.
Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

A Post-Processing Multipath/NLoS Bias Estimation Method Based on DBSCAN

Sensors
Positioning based on Global Navigation Satellite Systems (GNSSs) in urban environments always suffers from multipath and Non-Line-of-Sight (NLoS) effects. In such conditions, the GNSS pseudorange measurements can be affected by biases disrupting the GNSS-
