The large-scale, high-strength, super-tough, and multifunctional nacre-like heterocyclic aramid (HA)/MXene@polypyrrole (PPy) (HMP) nanocomposite papers were fabricated using the in-situ assembly of PPy onto the HA/MXene hydrogel *** "brick-and-mortar" layered structure and abundant hydrogen-bonding interactions among MXene, PPy, and HA respond cooperatively to external stress and effectively increase the mechanical properties of HMP nanocomposite *** templating effect from HA/MXene was utilized to guide the assembly of conducting polymers, leading to high electrical conductivity and outstanding electromagnetic interference shielding performance. Robust, ultra-flexible, and multifunctional MXene-based electromagnetic interference (EMI) shielding nanocomposite films exhibit enormous potential for applications in artificial intelligence, wireless telecommunication, and portable/wearable electronic equipment. In this work, a nacre-inspired multifunctional heterocyclic aramid (HA)/MXene@polypyrrole (PPy) (HMP) nanocomposite paper with large-scale, high strength, super toughness, and excellent tolerance to complex conditions is fabricated through the strategy of HA/MXene hydrogel template-assisted in-situ assembly of PPy. Benefiting from the "brick-and-mortar" layered structure and the strong hydrogen-bonding interactions among MXene, HA, and PPy, the paper exhibits remarkable mechanical performances, including high tensile strength (309.7 MPa), outstanding toughness (57.6 MJ m-3), exceptional foldability, and structural stability against ultrasonication. By using the template effect of HA/MXene to guide the assembly of conductive polymers, the synthesized paper obtains excellent electronic conductivity. More importantly, the highly continuous conductive path enables the nanocomposite paper to achieve a splendid EMI shielding effectiveness (EMI SE) of 54.1 dB at an ultra-thin thickness (25.4 mu m) and a high specific EMI SE of 17,204.7 dB cm2 g-1.

俄汉天文学术语中许多抽象概念都需要借助方位隐喻才能生成新概念,形成新术语。方位隐喻尤其是以“上、下”源域为代表的隐喻,在其基本空间意义的基础上已经逐渐衍生出了具有其他意义的隐喻概念,如状态意义、社会地位意义、时间意义、... 详细信息

俄汉天文学术语中许多抽象概念都需要借助方位隐喻才能生成新概念,形成新术语。方位隐喻尤其是以“上、下”源域为代表的隐喻,在其基本空间意义的基础上已经逐渐衍生出了具有其他意义的隐喻概念,如状态意义、社会地位意义、时间意义、范围意义等。因此,文章以俄汉天文学术语中方位隐喻“上、下”域为研究对象,对比分析两种语言间方位隐喻的异同,并尝试剖析其背后原因。

在水库管理中,准确评估水质至关重要。然而,数据收集的不确定性和水质因子权重分配的局限性均会对评估结果产生影响。为了解决这一问题,以大伙房水库为研究对象,开发了一种新的水质综合评价方法,该方法结合了随机森林算法(RF)、优劣解距离法(TOPSIS)和蒙特卡洛模拟(MCS)。首先根据实测的月均水质数据,通过MCS生成了一组正态分布的数据集。然后,利用RF赋权为TOPSIS方法分配权重,并借助隶属函数对水质进行综合评价。通过计算分析,得出的结果与辽宁省的月度水环境质量状况报告提供的水质等级相符,这表明此方法能为大型水库的水质评估提供有力的技术支持。

A novel chaotic oscillator in wavelength domain by using a tunable fibre laser is proposed. The generator of chaos in wavelength is composed of fibre Bragg grating （FBG） with hybrid delayed feedback loop which induces wavelength nonlinearity. The dynamical regime of wavelength is ruled by a differential difference equation. We give the numerical simulation of the experimental setup and discuss its application in an optical encryption system.

Earthquake simulator tests of a 1/6-scale nine-story reinforced concrete frame-wall model are described in the paper. The test results and associated numerical simulation are summarized and discussed. Based on the test data, a relationship between maximum inter-story drift and damage state is established. Equations of variation of structural characteristics （natural frequency and equivalent stiffness） with overall drifts are derived by data fitting, which can be used to estimate structural damage state if structural characteristics can be measured. A comparison of the analytical and experimental results show that both the commonly used equivalent beam and fiber element models can simulate the nonlinear seismic response of structures very well. Finally, conclusions associated with seismic design and damage evaluation of RC structures are presented.

A photoelectric hybrid optical bistable device (OBD) is investigated by using fibre Bragg gratings as a light-intensity modulator. A new operation with two feed signals is proposed, and with this method the output characteristic of the OBD is remarkably improved. The potential application of such a device in optic stabilizer for fibre laser is also briefly discussed.
