SUMMARY: Long non‐coding RNAs (lncRNAs) play crucial roles in various biological processes in plants. However, the functional mechanism of lncRNAs in fruit ripening, particularly the transition from unripe to ripe stages, remains elusive. One such lncRNA1840, reported by our group, was found to have important role in tomato fruit ripening. In the present study, we gain insight into its functional role in fruit ripening. CRISPR‐Cas9 mediated lncRNA1840 mutants caused the delayed tomato fruit ripening. Notably, loss function of lncRNA1840 did not directly impact ethylene signaling but rather delay ethylene synthesis. Transcriptomic analysis revealed differences in the expression of ripening related genes in lncRNA1840 mutants, suggesting that it is involved in gene regulation of fruit ripening. We used Chromatin Isolation by RNA Purification (ChIRP)‐Seq to identify lncRNA1840 binding sites on chromatin. ChIRP‐seq suggested that lncRNA1840 had occupancy on 40 genes, but none of them is differentially expressed genes in transcriptomic analysis, which indicated lncRNA1840 might indirectly modulate the gene expression. ChIRP‐mass spectrometry analysis identified potential protein interactors of lncRNA1840, Pre‐mRNA processing splicing factor 8, highlighting its involvement in post‐transcriptional regulatory pathways. In summary, lncRNA1840 is key player in tomato plant growth and fruit ripening, with multifaceted roles in gene expression and regulatory networks. Significance Statement: Long non‐coding RNAs (lncRNAs) play important roles in various biological processes in plants, but the mechanism of action of lncRNAs during fruit ripening remains unexplored. lncRNA1840 was identified in tomato, which confirmed that it affected the ripening process of tomato fruit and achieved post‐transcriptional regulation by participating in alternative splicing, which improved the regulatory network of tomato fruit ripening and filled the gap of lncRNA in the field of fruit ripening.

Fiber organic electrochemical transistors (OECTs) hold significant promise for in vivo bio-signal amplification due to their minimally invasive and seamless integration with biological tissues. However, their use in monitoring rapid physiological changes, such as electrophysiological signals, has been constrained by slow response time, arising from their extensive channel dimensions. Here, we introduce a novel fiber OECT designed with a micro-scale vertical channel (F-vOECT) that substantially reduces the response time by an order of magnitude to 12 ms and achieves a maximum transconductance of 16 mS at zero gate bias, marking a substantial improvement over previous fiber OECTs. This compact and flexible fiber device demonstrates robust performance under cyclic switching, dynamic deformation and exhibits excellent biocompatibility. When subcutaneously implanted in rats, the F-vOECT enables stable, continuous electrocardiogram monitoring for 7 days, successfully identifying episodes of atrioventricular block. These capabilities illustrate its potential for clinical electrophysiological diagnostics. The design strategy of F-vOECT opens new avenues for developing fast-responsive fiber bioelectronic devices.

This manuscript expounds the crystallization behavior of CaO–SiO2–MgO–Al2O3 (CSMA) slags towards the smooth operation of the blast furnace, where a structure-oriented elucidation for viscous flow was highlighted for deeper understanding of the crystallization behavior. The CCT curves collected from confocal laser scanning microscopy showed that the initial crystallization temperatures decreased with lower CaO/SiO2 mass ratios, and the primary crystal phases transformed from a merwinite phase (Ca3MgSi2O8) with a stronger crystallization ability to a melilite solid solution (Ca2Al2SiO7–Ca2MgSi2O7) with a comparatively weaker crystallization ability, which correlates well with the variation of Mg/Al mole ratios in melilite and verifies the formation of Ca2MgSi2O7 as one of the main reasons for the poor fluidity of the slag. Furthermore, a higher viscosity was observed for modified slags with CaO/SiO2 mass ratios from 1.34 to 1.05, accompanied by the activation energy increased from 173.0 to 182.7 kJ/mol, which is consistent with the decreased NBO/Si value and the increased Q3/Q2 ratio detected by Raman spectra. The crystal phase with melting point higher than the discharged temperature and the enhanced degree of polymerization of the slag structure will lead to the poor fluidity of the slag, which should be emphasized in the actual modification of the blast furnace slag.

Rubber tire mold fouling is a severe problem leading to mold surface corrosion, tire defects, and extra energy consumption. Traditional mechanical and chemical cleaning is inefficient and induces mold surface damage. Low surface energy organic coating displays antiadhesive behavior but is susceptible to wear. Here, we develop a bioinspired Co-CeO2/MoS2 coating with effective mechanical robustness, corrosion resistance, and antifouling behavior by leveraging a slippery liquid-infused surface (SLIPS) strategy. The micro-nanostructure of the coating serves as mechanical stability and anticorrosion skeleton with the infused lubricant acting as a slippery antifouling surface. The variation of microstructure, mechanical strength, corrosion resistance, and antifouling behavior of the coating with individual and synergistic addition of CeO2 and MoS2 is systematically characterized. The slippery Co-CeO2/MoS2 coating shows excellent mechanical stiffness, corrosion resistance, and antifouling performances in rubber vulcanization conditions. [ABSTRACT FROM AUTHOR]

This paper focuses on a detection‐based resilient control issue for cyber‐physical systems (CPSs) subject to false data injection (FDI) attacks, where FDI attacks occur in the communication channels from the sensor‐to‐controller and controller‐to‐actuator. Firstly, to reduce the adverse impacts of FDI attacks on estimation performance, an unbiased estimator is constructed by tackling the equality‐constrained optimization problem. Then, an effective attack detection mechanism is devised by introducing a pseudo‐innovation sequence to formulate the detection function, which can successfully detect two‐channel FDI attacks. Based on these detection results, a resilient controller combining linear quadratic Gaussian and H∞$$ {H}_{\infty } $$ controllers is provided to guarantee the mean‐square asymptotic stability of CPSs with H∞$$ {H}_{\infty } $$ performance. Finally, the validity of the proposed resilient control approach is demonstrated by a simulation involving satellite control system. [ABSTRACT FROM AUTHOR]
