Lightweight End-to-End Diacritical Arabic Speech Recognition Using CTC-Transformer with Relative Positional Encoding
Published on 2025-10-21 by Haifa Alaqel, Khalil El Hindi @MDPI
Abstract: Arabic automatic speech recognition (ASR) faces distinct challenges due to its complex morphology, dialectal variations, and the presence of diacritical marks that strongly influence pronunciation and meaning. This study introduces a lightweight approach for diacritical Arabic ASR that employs a Transformer encoder architecture enhanced with Relative Positional Encoding (RPE) and Connectionist Temporal Classification (CTC) loss, eliminating the need for a conventional decoder. A two-stage traini[...]
Our summary: This study presents a lightweight approach for diacritical Arabic ASR using a Transformer architecture with Relative Positional Encoding and CTC loss. The model achieves a WER of 22.01% on the SASSC dataset, outperforming traditional systems while using significantly fewer parameters. It demonstrates that encoder-only Transformers can effectively model Arabic phonetics while being resource-efficient for practical applications.

Characterizing the Evolution of Multi-Scale Communities in Urban Road Networks
Published on 2025-10-21 by Yifan Wang, Yi Li, Xingwa Song, Shilong Wang, Ning Wang @MDPI
Abstract: The growing abundance of traffic data offers new opportunities to uncover dynamic traffic patterns in urban road networks, providing valuable insights for promoting sustainable mobility. By leveraging these data, road segments can be grouped into communities to capture the spatiotemporal correlations driving the dynamic evolution of traffic states. However, existing distance-based methods lack the capacity to facilitate multi-scale analysis of urban traffic patterns and are limited in capturing [...]
Our summary: This study introduces a traffic-data-driven method to identify multi-scale communities in urban road networks. It leverages traffic data and Dynamic Time Warping to reveal spatiotemporal traffic dynamics. The approach enhances urban transportation sustainability through improved traffic prediction and control.

ITS Sequencing Reveals the Changing Characteristics of Fungal Communities in Different Rice-Growing Substrates Under Salt Stress
Published on 2025-10-21 by Hang Zhou, Xiaole Du, Yin Lin, Liming Zhao, Naijie Feng, Dianfeng Zheng @MDPI
Abstract: The impact of substrates with different physicochemical properties on the response of rhizosphere fungi in rice to salt stress has not been fully explored. The purpose of this study is to reveal the adaptation characteristics of fungal colonies to salt stress under different substrate conditions and the relationship between different properties of substrates and fungal colonies. Four different substrates were set by adjusting the sand, peat moss, and laterite ratio, with different bulk density, [...]
Our summary: This study investigates how different rice-growing substrates affect fungal communities under salt stress. It examines the relationship between substrate properties and the adaptation of fungal colonies, particularly Ascomycota and Penicillium. Findings reveal that salt stress influences fungal abundance differently based on substrate characteristics, contributing to the understanding of fungal ecological functions.

A Scheme for Covert Communication with a Reconfigurable Intelligent Surface in Cognitive Radio Networks
Published on 2025-10-21 by Yan Xu, Jin Qian, Pengcheng Zhu @MDPI
Abstract: This paper proposes a scheme for enhancing covert communication in cognitive radio networks (CRNs) using a reconfigurable intelligent surface (RIS), which ensures that transmissions by secondary users (SUs) remains statistically undetectable by adversaries (e.g., wardens like Willie). However, there exist stringent challenges in CRNs due to the dual constraints of avoiding detection and preventing harmful interference to primary users (PUs). Leveraging the RIS’s ability to dynamica[...]
Our summary: This paper presents a covert communication scheme in cognitive radio networks using a reconfigurable intelligent surface. It optimizes transmit power, communication block length, and beamforming to maximize effective covert throughput while adhering to detection and interference constraints. Results show that RIS significantly enhances covert communication capabilities compared to traditional methods.
