Collaborative Visual Localization for Modular Self‐Reconfigurable Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Relative localization in modular self‐reconfigurable robots is challenged by hardware limitations, constrained fields of view, and sensor faults. This paper, based on the SnailBot platform, presents a vision‐based collaborative localization method that combines ArUco markers with learning‐based algorithms to enable robust pose estimation from ...

Identification of NLOS and Multi-Path Conditions in UWB Localization Using Machine Learning Methods

open access: yesApplied Sciences, 2020
In ultra-wideband (UWB)-based wireless ranging or distance measurement, differentiation between line-of-sight (LOS), non-line-of-sight (NLOS), and multi-path (MP) conditions is important for precise indoor localization.

Genetic testing in paediatric neurological disorders

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
In this study 390 paediatric patients with neurological disorders underwent genetic testing via exome sequencing, commercial panel, in‐house epilepsy, and movement disorder gene panels. Exome sequencing provides the highest diagnostic yield, and severe developmental delay and hypotonia predicted pathogenic variants in the exome sequencing cohort ...

Low Power Ultra‐Wideband Low‐Noise Amplifier for UWB Receiver

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
This paper presents a 4–13 GHz UWB LNA designed in a 65 nm CMOS process, adopting gate inductor‐assisted impedance matching and current reuse feed‐forward noise cancellation. The LNA achieves 16.9 dB gain, 4.3 dB minimum NF, and only 9.4 mW power consumption from a 1 V supply.
