The energy spectra of low-lying states of an exciton in a single and a vertically coupled quantum dots are studied under the influence of a perpendicularly applied magnetic field. Calculations are made by using the method of numerical diagonalization of the Hamiltonian within the effective-mass approximation. We also calculated the binding energy of the ground and the excited states of an exciton in a single quantum dot and that in a vertically coupled quantum dot as a function of the dot radius for different vaJues of the distance and the magnetic field strength.

This work proposes an event-triggered adaptive control approach for a class of uncertain nonlinear systems under irregular *** the constraints considered in most existing papers,here the external irregular constraints are considered and a constraints switching mechanism(CSM)is introduced to circumvent the difficulties arising from irregular output *** on the CSM,a new class of generalized barrier functions are constructed,which allows the control results to be independent of the maximum and minimum values(MMVs)of constraints and thus extends the existing ***,we proposed a novel dynamic constraint-driven event-triggered strategy(DCDETS),under which the stress on signal transmission is reduced greatly and no constraints are violated by making a dynamic trade-off among system state,external constraints,and inter-execution *** is proved that the system output is driven to close to the reference trajectory and the semi-global stability is guaranteed under the proposed control scheme,regardless of the external irregular output *** also verifies the effectiveness and benefits of the proposed method.

Metal and nano-ceramic nanocomposite coatings were prepared on the gray cast iron surface by the electrodeposition method. The Ni-Co was used as the metal matrix,and nano-Al2O3 was chosen as the second-phase particulates. To avoid poor inter-face bonding and stress distribution,the gradient structure of biology materials was found as the model and therefore the gradient composite coating was prepared. The morphology of the composite coatings was flatter and the microstructure was denser than that of pure Ni-Co coatings. The composite coatings were prepared by different current densities,and the 2-D and 3-D morphologies of the surface coatings were observed. The result indicated that the 2-D structure became rougher and the 3-D surface density of apices became less when the current density was increased. The content of nanoparticulates reached a maximum value at the current density of 40mA·cm^-2,at the same time the properties including microhardness and wear-resistance were analyzed. The microhardness reached a maximum value and the wear volume was also less at the current density of 40mA·cm^-2. The reason was that nano-Al2O3 particles caused dispersive strengthening and grain refining.

Two patients had a stage Ⅱa disease, five had a stage Ⅱb disease, and the other two had a stage Ⅲ disease of International Union Contrele Cancer (UICC). All of them were histologically and immunohistochemically confirmed SCC of esophagus. Immunohistochemical staining for neuron-specific enolase (NSE), synaptophsin (Syn) and chromogranin A exhibited strong immunoreactivity in all specimens. Three of the nine resected specimens showed foci of squamous cell carcinoma in situ. Metastasis was present in 7 of 9 adjacent lymph nodes. All the patients survived the operations and made an uneventful postoperative recovery. They received adjuvant systemic chemotherapy and local radiation therapy after discharge. During followup, three patients developed multiple liver, brain, lung and bone metastases and died between 5 and 18 mo after the diagnosis. Three patients developed widespread metastasis disease and died between 18 and 37 mo after the *** was no local tumor recurrence in these 6 *** other three

中华人民共和国史学科建设遇到了学科建制复杂、学科属性不明确等问题,直接影响到中华人民共和国史学科的高质量发展。中共党史党建学的设立,为加快推进中华人民共和国史的学科建设开辟了另一条通道。中华人民共和国史设置为中共党史党建学的二级学科,对于中华人民共和国史学科和中共党史党建学来说是相互作用、相互成就、相得益彰的事情。中共党史党建学,为中华人民共和国史学科发展提供根本的思想方法论指导和重要的学术支撑;中华人民共和国史,较好地夯实了中共党史党建学发展的历史基础和研究领域。处在新时代新征程的历史起点上,中华人民共和国史设置为中共党史党建学的二级学科,要坚持以中共党史党建学一级学科为统领,从研究内容和学术建制两个大的方向着力。

1956年,国务院统一领导的1956～1967年科学规划工作,包括制订十二年哲学社会科学规划和十二年科学技术规划两个部分。然而,由于十二年哲学社会科学规划没有得到执行,且规划文本一直未公布,因此十二年哲学社会科学规划工作长期湮没无闻,以致其重要作用被忽略乃至被遗忘。作为中华人民共和国首次制订全国哲学社会科学规划的初步实践,十二年哲学社会科学规划工作开创了当代中国制订哲学社会科学规划的先河,是当代中国哲学社会科学规划工作的源头。

1956年,为实现向现代科学进军的目标,周恩来亲自领导了1956—1967年科学规划工作,为新中国科学事业的发展倾注了大量心血。可以说,周恩来是新中国计划科学的积极推动者,是十二年科学规划工作的直接领导者,是十二年哲学社会科学规划工作的有力支持者。回望周恩来及其当时科学工作者制订科学规划时的“初心”,对于今天科学工作者的一个重要启示是:既要制订好科学规划,更要贯彻落实好科学规划;同时,制订科学规划必须有利于解放和发展科研生产力,能够最大限度地调动科研工作者的积极性、主动性和创造性。
