Xi’an Drum Music is a traditional form of Chinese music and its notes are recorded by Chinese Characters.Because Xi’an Drum Music is composed and translated by the elder musicians,Xi’an Drum Music becomes difficult to be protected.In this article,we use sparse coding and compressed coding to transfer the Chinese Character recording to genre and lyrics of Xi’ an Drum Music.Based on our dataset of Xi’an Drum Music,we set up a method to generate Xi’ an Drum Music similar to Huffman coding,a model named Xi’an Drum Music Generation via Variational Autoencoder（DMGVAE） and the accuracy of Xi’ an Drum Music generation increases to 0.73.Compressed coding on Xi’an Drum Music shows a novel method to generate Xi’ an Drum Music by compressed format,making potential application for generating the sparse traditional Chinese Music such as Xi’an Drum Music.

软枣猕猴桃为雌雄异株植物，适配雄性品种较少。为探究花粉直感效应对软枣猕猴桃果实品质的影响，科学配置授粉雄性品种，以长江1号软枣猕猴桃为母本，采集20个不同雄株的花粉进行人工授粉，分析长江1号当年坐果率及其果实品质，并基于主成分分析法综合评价其果实品质，筛选适配雄株。结果表明：长江1号软枣猕猴桃存在花粉直感效应，花粉对当年坐果率、单果重、果形指数、可溶性固形物含量、可滴定酸含量、固酸比、维生素C含量、多酚含量、黄酮含量、总氨基酸含量和总矿物质含量存在不同程度的影响，其中黄酮含量可提高103.45%，为影响最显著的指标；编号分别为SNXS005、SNXS003、SNXS020、SNXS014和SNXS017的雄株花期均与长江1号吻合，授粉后当年坐果良好且果实综合品质优异，具有作为长江1号适配雄株的潜力。研究结果可为软枣猕猴桃雄性品种的选育提供科学参考。

The construction of ecological civilization concerns the sustainable development of China and the realization of the magnificent goal of beautiful China. The carbon emission trading is a market- oriented environmental economic policy whose purose is to resolve environmental issues,using the efficiency principle of the marketlization mechanism to resolve environmental issues under the premise of the commercialization of carbon emission permits. It can simultaneously make the economic subject follow compatability of the costs and benefits,and embody the solution logic of internalizing the externality. The implementation of the carbon emission trading has obvious effect of costs and benefits,and can resolve environmental governance at a relatively low cost. It is an efficient system used by human society to face the climate warming. Thus,the state of art- level design and effective implementation of carbon emission trading should be strengthened,and continuously perfect the pricing mechanism and accelerate pace of the international cooperation of carbon emission trading.

Interface passivation engineering has been recognized as an effective way to simultaneously contribute to the optoelectronic characteristic and stability of perovskite solar cells(PSCs). Herein, a p-conjugated dual-ligand 1,4-phenylmercaptan(PHMT) is explored to rationally tailor the surface of perovskite film.The experimental and theoretical results show that the PHMT presents planar structure and obvious electron delocalization characteristics, which allow it to anchor on the surface of perovskite with a certain orientation, thereby promoting the transport of interface charge. Moreover, the two sulfhydryl groups in PHMT reduce the trap density of the perovskite film by passivating under-coordinated lead ions.Consequently, the PHMT-modified inverted device based on MAPbI_(3)(MA: methylammonium) achieves enhanced efficiency from 18.11%(control) to 21.11%, along with the ambient stability up to 3500 h.After being placed at 85 °C for 500 h or illuminated for 600 h, the modified device remains over 89%or 86% of initial efficiency. This discovery opens a new window for the choice of passivators to improve the performance of PSCs.

Two-dimensional(2D) ferromagnetic materials have been discovered with tunable magnetism and orbital-driven nodal-line features. Controlling the 2D magnetism in exfoliated nanoflakes via electric/magnetic fields enables a boosted Curie temperature(TC) or phase transitions. One of the challenges, however, is the realization of high TC2D magnets that are tunable, robust and suitable for large scale fabrication. Here, we report molecular-beam epitaxy growth of wafer-scale Fe3+XGeTe2films with TCabove room temperature. By controlling the Fe composition in Fe3+XGeTe2, a continuously modulated TCin a broad range of 185–320 K has been achieved. This widely tunable TCis attributed to the doped interlayer Fe that provides a 40% enhancement around the optimal composition X = 2. We further fabricated magnetic tunneling junction device arrays that exhibit clear tunneling signals. Our results show an effective and reliable approach, i.e. element doping, to producing robust and tunable ferromagnetism beyond room temperature in a large-scale 2D Fe3+XGeTe2fashion.

Sb_(2)S_(3)is a promising candidate for the flexible solar cells or the top subcells in tandem solar cells due to its wide-bandgap,less toxic,acceptable cost and progressive power conversion efficiency(PCE).However,the poor quality and high trap states of Sb_(2)S_(3)films limit the device performance further enhancement.Herein,we adopt a multidentate ionic liquid,tetramethylammonium hexafluorophosphate([TMA][PF_(6)])as a novel additive to address this issue.The octahedral[PF_(6)]~-contains six different oriented fluorine atoms with the lone pair electrons,which could coordinate with Sb atoms due to the multidentate anchoring.Thus,the high-quality Sb_(2)S_(3)film with low trap states has been achieved.Moreover,the Fermi level of the Sb_(2)S_(3)film has been upshifted,thereby showing an effective charge transfer.As a result,all photovoltaic parameters of the optimized Sb_(2)S_(3)devices are obviously enhanced,boosting the final PCE from 4.43(control device)to 6.83%.Our study about the multidentate anchoring is manifested to be an effective method to enhance the Sb_(2)S_(3)device performance.
