厦门小微企业知识产权托管治理的问题及对策

厦门市知识产权托管工作已由政府单向管理向以政府为主引导，企业、服务机构、行业协会、产业园区以及自贸区等载体参与其中的多元治理体系转变，并取得了良好的成效。但存在顶层设计缺失、托管机构服务能力不足、行业协会作用发挥不充分、氛围营造不够等问题。厦门市应通过加强监管力度、提高小微企业参与托管的意识、提升托管机构的服务能力、激励行业协会发挥作用、加强宣传等措施，进一步完善多元共治的治理体系，提升小微企业知识产权托管治理效能。     

Identifying aspirin polymorphs from combined DFT-based crystal structure prediction and solid-state NMR

A combined experimental and computational approach was used to distinguish between different polymorphs of the pharmaceutical drug aspirin. This method involves the use of ab initio random structure searching (AIRSS), a density functional theory (DFT)-based crystal structure prediction method for the high-accuracy prediction of polymorphic structures, with DFT calculations of nuclear magnetic resonance (NMR) parameters and solid-state NMR experiments at natural abundance. AIRSS was used to predict the crystal structures of form-I and form-II of aspirin. The root-mean-square deviation between experimental and calculated ¹H chemical shifts was used to identify form-I as the polymorph present in the experimental sample, the selection being successful despite the large similarities between the molecular environments in the crystals of the two polymorphs.     

Semilinear wave models with friction and viscoelastic damping

In this paper, we study the global (in time) existence of small data solutions to the Cauchy problem for the semilinear wave equation with friction, viscoelastic damping, and a power nonlinearity. We are interested in the connection between regularity assumptions for the data and the admissible range of exponents p in the power nonlinearity.

军事用语语义泛化缘由探析

军事用语语义泛化的原因主要有两点:一是从语言系统外部来看:主要与语用环境的相似、言语修辞活动、言语交际中的心理因素等社会文化语用条件有关联;二是从语言系统内部来看,主要与语言的经济性原则密切相关。     

论中小城市社区建设中的政府职能

我国中小城市社区建设尚处于起步阶段,运行机制不够健全,发展水平不高,体现出政府作用突出,社区自治权利淡化;社区居民参与不足;社区经济薄弱等特征。为此,在中小城市社区建设中,应进一步明确区(县)一级政府对城市的管理职能;建立和培育各类社会中介组织;理性区分政府对城市的行政管理与居民参与的社区自治管理;政府应提供社区公共品供给的制度保证并妥善解决社区发生的"外部性"问题。

"百无聊赖以诗鸣"--浅析梁启超《读陆放翁集诗四首》

梁启超《读陆放翁集四首》是近代军旅诗的代表作，其诗批评了当时诗坛的靡靡之风，赞扬了陆游诗中描述从军之乐的豪情壮乐，同时借古抒怀，表达了自己怀才不遇、壮志未酬但终不沉默的英雄气概。     

Inequalities for the Moments and Distribution of the Ladder Height of a Random Walk

We obtain upper bounds for the tail distribution of the first nonnegative sum of a random walk and for the moments of the overshoot over an arbitrary nonnegative level if the expectation of jumps is positive and close to zero. In addition, we find an estimate for the expectation of the first ladder epoch.
