Cyclic-conjugated linkages between planar-macrocydic molecules contribute to the robustness of the two-dimensional (2D) polymerization and extension of π-interactions. The fabrication of such linkages in 2D polymers remains challenging. Combining scanning tunneling microscope (STM) measurements and density functional theory (DFT) calculations, we demonstrate a linear polymerization of metal-free naphthalocyanine (NPc) molecules with [4]-radialene-like linkages on silver surfaces. Experimentally, by depositing NPc molecules on the Ag(110) surface and subsequent annealing up to 750 K, one-dimensional polymers are constructed along the [\(1\overline 1 0\)] direction. High-resolution STM images show a stem-leaf-like feature. STM simulations based on a linear polymer of NPc molecules linked by four-membered carbon rings, [4]-radialene-like structure, agree well with the experimental observations. DFT calculations reveal that the polymerization process includes detaching two-terminal H atoms of NPc molecules along [\(1\overline 1 0\)] direction, then bonding with a neighboring dehydrogenated NPc molecule by forming a four-membered ring. The dehydrogenation process can be promoted by on-surface impurities such as additional H atoms. Similar polymerizations have been achieved on Ag(111) surfaces in an amorphous way. Moreover, the energy gap of the NPc molecule decreases after linear polymerization, suggesting a red-shift for its optical absorption/scattering spectrum. Our study offers a new route to polymerize conjugated molecules with extended planar π-interactions.

风速预测是减小大规模风力发电对电网造成不利影响的有效手段,但是风速的非线性与非平稳性特点将给预测带来极大挑战。笔者采用一种基于灰色关联度的层次聚类算法HCGRDA和带高斯扰动的模拟退火果蝇算法GDSAFOA优化SVM的短期风速组合预测方法。该方法利用HCGRDA获得相似的样本空间,采用集合经验模态分解EEMD算法分解风速时间序列,利用经混沌相空间重构的SVM与NARX网络进行线性组合预测。以山西某风电场实测数据为例进行建模,结果表明本文所采用方法合理、有效。

目的:了解精神卫生和心理咨询从业人员对性少数群体的认知、态度和接纳程度,以及可能的影响因素;了解精神卫生与心理咨询从业人员对性倾向扭转治疗的态度,以及扭转治疗的实施现状;为中国同性恋完全去病理化工作提供一定的数据支持。方法:采用自编问卷,结合电话访谈进行线上和线下调查。自编问卷包括基本信息、性少数群体认知、精神卫生与心理咨询从业人员对同性恋来访者接待态度量表和扭转治疗的操作。线下调查采用配额抽样,各地合作机构和个人经过测试培训后完成各地的问卷发放和回收,线上调查由某医学类专业网站发放问卷。有效样本996个,来自全国29个省级行政单位。结果:(1)精神卫生与心理咨询从业人员对同性恋群体的态度得分为3.05,"接待感受"因子平均分为3.11,"接待意愿"因子平均分为3.02。(2)对同性恋的态度在性别认同、职业领域、海外经历、学历、培训程度、是否接待过同性恋、是否支持扭转治疗上存在显著差异。(3)调查对象中从未接受过和很少接受过同性恋相关培训的分别为33.6%和36.1%,对性倾向能否改变最主要的看法是"部分人可以改变",对同性恋的定性最主要的看法是"正常行为"。(4)62.1%的调查对象反对扭转治疗。(5)扭转治疗个案持续时间从1个月以下到6个月以上不等,费用高于普通治疗或咨询。方法以心理治疗为主,最主要的治疗结果为"未改变性倾向"。(6)"是否接受过有关培训"和"对同性恋认识程度"对调查对象对同性恋群体的态度以及是否支持扭转治疗有显著预测作用。结论:总体来说,精神卫生和心理咨询从业人员对同性恋者的接待感受和接待意愿较好,但仍有部分受访者对同性恋者有潜在歧视。性倾向扭转治疗在中国仍然被使用。影响精神卫生与心理咨询从业人员对性少数群体态度的关键因素是他们对性少数群体相关知识的掌握程度,态度对是否支持扭转治疗有显著影响。开展多元性别培训是加强认知与改善态度的重要方法。

计算鬼成像相较于传统鬼成像的成像结构更加简单,并可以设计不同类型的散斑进行成像,所以成像质量和成像时间都得到了进一步的提升,近期在层析成像领域展示出了巨大的应用潜力。提出一种新的基于计算鬼成像的层析成像方案,并在计算鬼成像的架构下,通过一组测量得到物体不同层面的二维平面信息,从而获得物体的完整的三维图像信息。进而对上述方案进行了理论分析和数值仿真,仿真过程以光路中不同位置的两个平面上的物体代表层析成像的两个层面。结果表明,通过计算鬼成像,可以同时复原出两个不同层面上物体的清晰的像,从而证明了该方案的可行性,为基于计算鬼成像的层析成像的应用提供了新的思路。

Silk damping in scalar-induced gravitational waves: a novel probe for new physics

引用

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 79-85页

Silk damping is well known in the study of cosmic microwave background（CMB） and accounts for suppression of the angular power spectrum of CMB on large angular multipoles. In this article, we study the effect of Silk damping on the scalar-induced gravitational waves（SIGWs）. Resulting from the dissipation of cosmic fluid, the Silk damping notably suppresses the energydensity spectrum of SIGWs on scales comparable to a diffusion scale at the decoupling time of weakly-interacting particles. The effect offers a novel observable for probing the underlying particle interaction, especially for those mediated by heavy gauge bosons beyond the standard model of particles. We anticipate that pulsar timing arrays are sensitive to gauge bosons with mass ～10～3-10～4 GeV, while space-and ground-based interferometers to those with mass ～10～7-1012GeV, leading to essential complements to on-going and future experiments of high-energy physics.
