教师学术增值评价被认为更符合学术研究规律和知识生产创新要求,能够在一定程度上减少“唯论文”、脱域化等不科学倾向所导致的“学术泡沫”,故而在新时代高等教育评价实践改革中受到推崇。但是由于学术增值评价的理念认知偏差、学科壁垒尚未打破、育人反哺价值难以凸显等,导致教师学术增值评价变革陷入重重困境。未来应从理念认知、知识分类、功能重塑等方面进行变革,以改变学术生态、促使教师产生持续性学术创新动能。

We investigate a graphene-coated nanowire waveguide(GCNW) composed of two suspended wedge porous silicon nanowires and a thin Ag partition. The plasmonic characteristics of the proposed structure in terahertz(THz) frequency band are simulated by the finite element method(FEM). The parameters including the gap between the nanowires and Ag partition, the height of the nanowire, the thickness of the Ag partition, and the Fermi level of graphene, are optimized. The simulation results show that a normalized mode field area of ~10-4 and a figure of merit of ~100 can be achieved. Compared with the cylindrical GCNW and isolated GCNW, the proposed wedge GCNW has good electric field enhancement.A waveguide sensitivity of 32.28 is obtained, which indicates the prospects of application in refractive index(RI) sensing in THz frequency band. Due to the adjustable plasmonic characteristics by changing the Fermi level(EF), the proposed structure has promising applications in the electro-optic modulations, optical interconnects, and optical switches.

Within the framework of the semiclassical Boltzmann-Uehling-Uhlenbeck transport model,we investigate the effects of symmetry energy on the sub-threshold pion using the isospin MDI interaction with the stiff and soft symmetry energies in the central collision of 48Ca+48Ca at the incident beam energies of 100,150,200,250 and 300 MeV/*** find that the ratio ofπ- /π+ of sub-threshold charged pion production is greatly sensitive to the symmetry energy,particularly around 100 MeV/nucleon *** sensitivity of sub-threshold charged pion production to nuclear symmetry energy may reduce uncertainties of probing nuclear symmetry energy via heavy-ion collision.

由于多自由度非线性结构参数识别是反问题,其解具有不确定性,为提高识别效率及识别结果的精度,基于序列二次规划法并通过数值试验分析研究影响参数识别鲁棒性能的各个因素。研究结果表明:噪声不影响识别效率但影响识别结果精度;基于时域信息构建优化目标函数时,时程长度影响识别效率和识别结果的精度,一般时程长度选取8倍结构基本周期时能取得较好效果;在描述非线性力学行为时,Bouc-Wen模型相比双线性模型适应性更强,具有更好的识别效果;非线性结构在激励强度较大情况下识别得到的参数值更具可靠性;对相关性较弱参数,可通过分步骤识别,减小参数识别数量,从而提高参数识别效率。

Pangolins are among the most critically endangered animals due to heavy poaching and worldwide trafficking. However, their demographic histories and the genomic consequences of their recent population declines remain unknown. We generated high-quality de novo reference genomes for critically endangered Malayan(Manis javanica, MJ) and Chinese(M. pentadactyla, MP) pangolins and re-sequencing population genomic data from 74 MJs and 23 MPs. We recovered the population identities of illegally traded pangolins and previously unrecognized genetic populations that should be protected as evolutionarily distinct conservation units. Demographic reconstruction suggested environmental changes have resulted in a population size fluctuation of pangolins. Additionally, recent population size declines due to human activities have resulted in an increase in inbreeding and genetic load. Deleterious mutations were enriched in genes related to cancer/diseases and cholesterol homeostasis, which may have increased their susceptibility to diseases and decreased their survival potential to adapt to environmental changes and high-cholesterol diets. This comprehensive study provides not only high-quality pangolin reference genomes, but also valuable information concerning the driving factors of long-term population size fluctuations and the genomic impact of recent population size declines due to human activities, which is essential for pangolin conservation management and global action planning.
