Accurate tilt detection is vital in determining the instability of bridges and foundations; however, existing systems depend on batteries, cables, and periodic calibration. We present a battery-free wireless tilt sensor based on a dual-band microwave structure that allows self-calibration against varying environmental effects and distance ambiguity. The sensor uses harvested energy from signals transmitted by a reader and integrates sensing, communication, and antenna functionalities into one device. The measurement results show that tracking the phase difference between two bands mitigates environmental factors. A 36° phase shift over a tilt range of -10° to +10° is observed, corresponding to a sensitivity of 1.8° of measured phase per 1° of actual tilt. The system is fully integrated, IoT-ready, and facilitates easy integration into a sensor network. It also creates a reliable platform for monitoring critical infrastructures in real-time to ensure rapid measurement of tilts from multiple sensors.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":" ","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13558597/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148177302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present a single-step, physics-informed neural approach to nonlinear compensation that preserves the parallel structure of the Volterra-series transfer function while learning data-driven corrections, unlike widely used digital back-propagation, which reconstructs propagation with numerous cascaded steps and therefore incurs high computational complexity and latency at comparable performance. The method integrates a trainable linear kernel with a compact nonlinear mapping and provides a hardware-suitable architecture. In a 1125-km WDM link, NN-VS matches the maximum performance achieved by leading digital back-propagation variants at 19% computational complexity and 1/25 latency; in a 12,057-km WDM system, the reductions increase to ~6.6% and ~1/176, yielding an efficiency improvement exceeding 2,600×. These results demonstrate that single-step, parallel compensation-augmented by learned corrections-helps mitigate performance-complexity-latency trade-offs, suggesting a pathway for the efficient deployment of nonlinear compensation in next-generation coherent optical networks.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":" ","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13542127/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148159181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we investigate interfacial stability in devices employing polymeric PTAA, self-assembled monolayer MeO-2PACz, and a sequential PTAA/MeO-2PACz bilayer. Devices were evaluated under space-relevant conditions, including vacuum, AM0 illumination and thermal cycling spanning -40 °C to 90 °C. While MoO-2PACz enables high efficiency through interfacial engineering, it exhibits severe degradation under thermal tress due to thermomechanical mismatch with the perovskite layer, leading to interfacial defects and phase instability. In contrast, PTAA provides improved thermal stability but lower efficiency. The bilayer structure achieves both high efficiency and enhanced durability, retaining 73% of its initial performance after thermal cycling. This improvement arises from the polymeric layer mitigating thermomechanical stress and suppressing δ-phase transitions. These results suggest efficient interfacial thermomechanical engineering and strategy to thermal durability in PSCs for harsh space environments.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":" ","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13260336/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148152381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although commercial alternatives are available, these systems remain slow, expensive, and limited in flexibility, indicating clear opportunities for improvement. Coded‑imaging strategies, including single‑pixel imaging (SPI), offer promising alternatives by enabling computational reconstructions with spectral resolution through parallel detection. When combined with conventional cameras via data fusion (DF), these reconstructions can achieve high spatial resolution. However, traditional implementations often rely on spectrometers, which suffer from limited bandwidth and low-speeds acquisition, restricting SPI's versatility. To overcome these challenges, in this work is developed a hyperspectral single‑pixel microscopy platform (HySPM) assisted by DF. The system employs a customized optical setup that disperses light into spectral components, captured by a high‑speed line‑scan camera in parallel detection. Full Hadamard scans of 64×64 pixels are completed in 0.82 s at 10 kHz. Up to 73 spectral bands are acquired in parallel with 4 nm resolution, without compressive algorithms. Performance is validated through reflected intensity and fluorescence imaging. DF further integrates HySPM with high‑resolution monochrome images, expanding reconstructions from 64×64 to 605×605 pixels while enhancing spatial detail and preserving spectral signatures. HySPM thus provides a scalable, cost‑effective solution that bridges temporal limitations in current hyperspectral implementations.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":" ","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13486503/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148038289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite substantial advances in scientific natural language processing for scientific document analysis, automatic quantitative extraction of quantitative data from visual plots remains a challenge due to graphical heterogeneity, noise, and non-standardized formats. In this paper, we present ChartRecover, a deep learning-based framework for end-to-end extraction and reconstruction of chart data from scientific figures. ChartRecover adopts object detection to robustly identify graphical elements across diverse plot types, and introduces a coordinate transformation strategy that aligns visual pixel coordinates with real-world numerical values through axis tick-mark alignment and adaptive conversion. We benchmark ChartRecover across a wide range of figure styles and perturbation conditions, demonstrating strong generalization and high-fidelity recovery performance. The extracted structured data enables downstream applications such as structure-property relationship mining and automated scientific verification. Our work advances machine understanding of scientific figures and provides a scalable tool to enhance research transparency, reproducibility, and data accessibility.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":" ","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13458524/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147984736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Martian environment, characterised by a tenuous atmosphere, extreme thermal variations, and diverse, often inaccessible terrain, presents fundamental challenges to the operational range and efficiency of conventional rovers and landers. Aerobots can overcome many of these limitations by enabling rapid regional surveys, accessing high-priority sites beyond rover reach, and supporting human exploration through environmental reconnaissance. Drawing on insights from past planetary missions, including the Ingenuity helicopter, the framework integrates planetary science constraints with aerospace engineering principles to address aerodynamic performance, structural integrity, autonomy, and environmental resilience. Central to this work is the Mars Aerobot Design Thinking Matrix, a decision-support tool that links mission objectives to testable engineering requirements, enabling systematic trade-off analysis across configuration, energy strategy, and operational margins. The proposed framework aims to guide the development of aerobots capable of sustained and scientifically productive operations in the unique conditions of Mars.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"5 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13187032/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147977523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
