Robust Regression and Redundant Measurement Noise Estimation Adaptive Filtering for Localization in Urban Environments
Published on 2025-02-20 by Li Zha, Hai Zhang, Aiping Wang, Cancan Tao @MDPI
Abstract: This paper focuses on a solution of target self-positioning when a Global Navigation Satellite System (GNSS) is denied. It is composed of Inertial Navigation Systems (INS), Signals of Opportunities (SOPs), and a navigation prototype. One of the options for navigation via SOP (NAVSOP) is to utilize cellular signals, such as Long Time Evolution (LTE). When the prior information is insufficient, the location of the base station (BS) is obtained by collecting the demodulation of the downlink signal,[...]
Our summary: Solution for target self-positioning in urban environments using INS, SOPs, and NAVSOP with LTE signals, introducing robust regression and RMNCE for improved accuracy, validated through simulation and vehicle test.

Tracking the Evolution of Cutaneous Melanoma by Multiparameter Flow Sorting and Genomic Profiling
Published on 2025-02-19 by Luca Roma, Thomas Lorber, Sabrina Rau, Michael T. Barrett, Caner Ercan, Federica Panebianco, Salvatore Piscuoglio, Katharina Glatz, Lukas Bubendorf, Christian Ruiz @MDPI
Abstract: Intratumoral heterogeneity and clonal evolution are pivotal in the progression and metastasis of melanoma. However, when combined with variable tumor cellularity, intratumoral heterogeneity limits the sensitivity and accuracy of uncovering a cancer’s clonal evolution. In this study, we combined fluorescence-activated cell sorting (FACS) with whole-exome sequencing (WES) to investigate the clonal composition and evolutionary patterns in seven melanoma biopsies obtained from three pa[...]
Our summary: Tracking clonal evolution in melanoma using multiparameter flow sorting and genomic profiling reveals significant heterogeneity and highlights the importance of analyzing tumor trajectories.

Characterization of Laser-Textured Surfaces of Parts of a Biodegradable Polymer
Published on 2025-02-19 by Petronela-Daniela Rusu (Ostahie), Oktawian Bialas, Anna Wozniak, Marcin Adamiak, Augustine Appiah, Catalin Tampu, Simona-Nicoleta Mazurchevici, Panagiotis Kyratsis, Anastasios Tzotzis, Alexandra Nedelcu, Teodor-Daniel Mindru, Dumitru Nedelcu @MDPI
Abstract: Surface texturing entails surface alteration through forming, microgrooving, microdimpling, and microchanneling. This is achieved by laser micromachining, in addition to other related methods, of a substrate surface. The present paper describes the surface characteristics obtained after the laser texturing of a biodegradable polymer (Arbofill Fichte) with four and six passes in hexagonal and square patterns. The results of the wettability test indicate that this biodegradable polymer has a surfa[...]
Our summary: Characterization of laser-textured surfaces of biodegradable polymer parts. Surface alteration achieved through laser micromachining. Hexagonal geometry offers greater stability and consistency compared to square geometry.
