The fault characteristics of rolling bearing with variable rotational speed are usually related to shafting speed and vary with time. Moreover, the rolling bearing fault characteristics are easily submerged by the noises. To address these issues, an adaptive time-varying comb filtering (ATVCF) method that combines the merits of comb filter and adaptive timevarying filtering (ATVF) is proposed and applied to extract the fault-related component from the envelope signal of rolling bearing. And on this basis, via the joint application of ATVCF and order tracking (OT), a fault characteristics extraction methodology for rolling bearing with variable rotational speed, namely ATVCF-OT, is developed. In the ATVCF-OT, the ATVCF method can adaptively extract time-varying harmonic components containing rolling bearing fault information from the rolling bearing fault vibration signal, and the OT analysis can effectively stabilize the time-varying rolling bearing fault features. Therefore, the ATVCF-OT methodology is particularly suitable for fault feature extraction of rolling bearing with variable rotational speed. Simulation and experimental results indicate that the ATVCF-OT method can effectively remove the fault-unrelated components and highlight the fault features of rolling bearing. The comparisons with the direct envelope order method and the ensemble empirical mode decomposition (EEMD)-based envelope order method demonstrate the advantages of the proposed ATVCF-OT method.

The application of conventional absorbing materials is limited due to complex preparation process andpoor transparency caused by fillers. In this study, a highly transparent ionic organogel was preparedby photocuring a dimethyl sulfoxide (DMSO) solution of a polymerizable magnetic cationic monomer[DAC]5[Dy(NCS)8]. Both components of organogel, which are the photopolymerizable magnetic cationicmonomer and polar solvent DMSO, have an important effect on the magnetic losses and dielectric lossesproperties of the organogel respectively. By tuning the mass ratio of DMSO to the monomer and the contentof the cross-linker, the complex permittivity of the gel could be effectively adjusted to improve theimpedance matching, and finally a gel with excellent wave absorption properties and good tensile propertieswas obtained. The optimum organogel was fabricated with a minimum reflection loss of 45.9 dBand a broadest effective absorption bandwidth (EAB) of up to 5.2 GHz, and effective absorption in the millimeterband (26.5–40 GHz) which is within the fifth generation (5G) mobile networks. With the advantagesof simple preparation method, arbitrary shape and good adhesion to a variety of substrates andcomplex surfaces, this multifunctional gel provides a new solution for complex scenarios requiring opticaltransparency and simultaneous absorption of electromagnetic waves.

Long noncoding RNA: multiple players in gene expression
( Xiaochang Chen ),( Yunmei Sun ),( Rui Cai ),( Guoqiang Wang ),( Xiaoyan Shu ),( Weijun Pang ) 생화학분자생물학회(구 한국생화학분자생물학회) 2018 BMB Reports Vol.51 No.6
Previously considered as a component of transcriptional noise, long noncoding RNAs (lncRNAs) were neglected as a therapeutic target, however, recently increasing evidence has shown that lncRNAs can participate in numerous biological processes involved in genetic regulation including epigenetic, transcriptional, and post-transcriptional regulation. In this review, we discuss the fundamental functions of lncRNAs at different regulatory levels and their roles in metabolic balance. Typical examples are introduced to illustrate their diverse molecular mechanisms. The comprehensive investigation and identification of key lncRNAs will not only contribute to insights into diseases, such as breast cancer and type II diabetes, but also provide promising therapeutic targets for related diseases.
