Vinylene‐linked covalent organic frameworks (COFs) have attracted enormous attention for photocatalytic H2 evolution from water because of their fully conjugated structures, high chemical stabilities, and enhanced charge‐carrier mobilities. In this work, two novel vinylene‐linked COFs with tuned cyano contents were successfully synthesized and then employed as photocatalysts for H2 generation. Notably, the photocatalytic H2 production rate of the COF with the higher cyano content reached 73 μmol h−1 under visible light irradiation, which is 2.4 times higher than that with the lower content (30 μmol h−1). Both the experimental and computational results demonstrated that the rational design incorporating cyano groups into COF skeletons could precisely tune the corresponding energy levels, expand the visible‐light absorption, and improve the photoinduced charge separation. This work not only provides a simple method for modulating the photocatalytic activities of COFs at the molecular level, but also affords interesting insights into the relationship between their structures and photocatalytic performance.

As a primitive hexaploid wheat resource distributed only in Tibet, Tibetan semi-wild wheat (Triticum aestivum subsp. tibetanum Shao) possesses unique characteristics that could be exploited in wheat breeding programs. Its good root system could offer a stable platform for above-ground components. To detect possible excellent locus for root traits from Tibetan semi-wild wheat, we identified QTLs for root traits using a recombinant inbred line population derived from a cross between Tibetan semi-wild wheat Q1028 and Zhengmai 9023. A total of 15 QTLs on eight chromosomes were detected, including four major QTLs, QMrl.sau-7B, QTrl.sau-4B, QAd.sau-7A, and QSa.sau-4B. The phenotypic variation explained by each of these QTLs ranges from 5.67% to 16.68%. Positive alleles of six QTLs were derived from Q1028. Several novel QTLs for root traits were identified. In addition, significant correlations were detected amongst root traits and agronomic traits. Taken together, these results suggest that Tibetan semi-wild wheat and the newly identified novel QTLs could be useful in future breeding programs. Key words: Tibetan semi-wild wheat, recombinant inbred line, root trait, quantitative trait locus, correlation. Résumé : En tant que ressource génétique primitive pour le blé hexaploïde qui est uniquement présente au Tibet, le blé tibétain semi-sauvage (Triticum aestivum subsp. tibetanum Shao) possède des caractéristiques uniques qu'il serait possible d'exploiter en amélioration génétique du blé. Son bon système racinaire pourrait offrir une plate-forme stable pour les parties aériennes. Afin de détecter des locus contribuant à l'excellent système racinaire du blé tibétain, les auteurs ont réalisé une analyse QTL pour des caractères racinaires au sein d'une collection de lignées recombinantes fixées issue du croisement entre le blé tibétain Q1028 et Zhengmai 9023. Un total de 15 QTL sur huit chromosomes a été détecté, incluant quatre QTL majeurs (QMr1.sau-7B, QTrl.sau-4B, QAd.sau-7A et QSa.sau-4B). La part de la variation phénotypique expliquée par chacun de ces QTL variait entre 5,67 et 16,68 %. Des allèles positifs pour six des QTL étaient dérivés de Q1028. Plusieurs nouveaux QTL pour des caractères racinaires ont été identifiés. De plus, des corrélations significatives ont été détectées entre les caractères racinaires et agronomiques. Ensemble, ces résultats suggèrent que le blé tibétain semi-sauvage et les QTL nouvellement identifiés pourraient s'avérer utiles dans le cadre de programmes d'amélioration génétique.

The growing utilization of single-phase pulse width modulation (PWM) rectifiers in various applications has spurred interest in detecting and monitoring faults in these devices. In particular, voltage and current sensors play a crucial role in the control loop of these rectifiers. However, sensor faults can significantly affect the converter's performance and availability. This paper introduces a novel and efficient method for detecting and decoupling sensor faults in single-phase PWM rectifiers. The proposed method utilizes residual generation and incorporates an extended filter within the rectifier. Unlike conventional filters, the presented fault detection and isolation (FDI) method effectively eliminates the influence of disturbances on the residual signal. This feature helps prevent false alarms in the monitored system, ensuring reliable fault detection. To evaluate the effectiveness of the approach, hardware-in-the-loop and simulation tests were conducted. The results from these tests provide substantial evidence supporting the efficacy of the proposed method. The hardware-in-the-loop experiments involved real-world implementation, validating the practicality and reliability of the approach. Meanwhile, simulation tests allowed for a comprehensive analysis of system behavior and performance under various fault scenarios. The findings demonstrate the rapid and dependable nature of the proposed method for detecting and decoupling sensor faults in single-phase PWM rectifiers. By effectively mitigating the impact of disturbances on the residual signal, false alarms are minimized, ensuring accurate fault detection. The experimental validation highlights the practical applicability and effectiveness of the proposed approach, making it a valuable contribution to fault detection in single-phase PWM rectifiers.
