Winning strategies in club games and their applications

We present results concerning winning strategies and tactics in club games on ??λ. We show that there is generally no winning tactic for the player trying to get inside the club. The bound‐countable game turns out to be rather fruitful and adds to some previous results about the construction of elementary substructures and their localization in certain intervals. We show that Player II has a winning strategy in the bound‐countable game, thus establishing a new ZFC result. The applications given are new proofs for two cardinal diamonds and the impossibility of collapsing cardinals to ?₂ under certain conditions (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)     

Destructibility of stationary subsets of Pκλ

For a regular cardinal κ with κ ^<κ = κ and κ ≤ λ , we construct generically (forcing by a < κ‐closed κ ⁺‐c. c. p. o.‐set ℙ₀) a subset S of {x ∈ P _κ λ : x ∩ κ is a singular ordinal} such that S is stationary in a strong sense (F ^IA_κ λ ‐stationary in our terminology) but the stationarity of S can be destroyed by a κ ⁺‐c. c. forcing ℙ* (in V ^ℙ) which does not add any new element of P _κ λ . Actually ℙ* can be chosen so that ℙ* is κ‐strategically closed. However we show that such ℙ* itself cannot be κ‐strategically closed or even <κ‐strategically closed if κ is inaccessible.

网络游戏障碍人群大脑功能网络rich club结构的改变

网络游戏障碍（internet gaming disorder,IGD）极大的影响了青少年的学习与生活．IGD于2013年被纳入《精神障碍诊断与统计手册》第5版（DSM-5）,但其神经机制还不清楚．本研究通过静息态功能磁共振成像研究30例IGD被试以及年龄、性别与之匹配的30例健康对照,分析他们大脑功能网络的rich club结构的差异．结果表明,IGD组和对照组均存在rich club结构,rich club脑区主要包含默认模式、执行控制、突显、感觉运动、听觉与视觉网络中的脑区;同时IGD组的rich club连接增加;此外,IGD组的右侧眶部额下回的度显著高于健康对照组.这些发现表明了IGD人群大脑功能网络的rich club结构发生了改变．     

浙江省经营性健身俱乐部消费者特征分析

采用问卷调查、文献资料和数理统计等方法,对浙江省经营性健身俱乐部消费者特征进行分析,旨在了解消费者的性别、年龄、学历、职业等基本特征．结果表明：消费者的体育消费动机以强身健体为主;健美操是浙江省经营性健身俱乐部消费者首选的消费项目;消费者对俱乐部健身指导员的依赖性较大,对俱乐部相关服务、配套设施、环境等有较高要求．     

Determination of antiretroviral drugs for buyers’ club in Switzerland using capillary electrophoresis methods

Human immunodeficiency virus-acquired immunodeficiency syndrome continues to be a major global public health issue, having claimed almost 33 million lives to date. Due to the high cost of antiretroviral treatment, access to these drugs remains difficult for vulnerable populations, such as migrants and people living in prisons, who often do not have health insurance. These factors lead to poorer health outcomes and higher transmission rates. The personal importation scheme for unapproved generics from foreign countries is one option to access affordable human immunodeficiency virus treatment. However, the risk of importing falsified medicine remains high, and the quality control of unapproved drugs is lacking. In this context, three CE methods for the analysis of nine antiviral drugs found in commercial pharmaceutical formulations were evaluated. The selected compounds were emtricitabine, tenofovir disoproxil, tenofovir alafenamide, rilpivirine, efavirenz, raltegravir, dolutegravir, abacavir, and lamivudine. The developed methods were successfully applied to determine the active pharmaceutical ingredients of commercial formulations and unapproved generics. The quality control of unapproved generics by CE is an attractive approach due to its good standard of quality, low cost, ecofriendliness, and ease of implementation.     

一种新的移动Agent安全体系设计方法

针对现有移动Agent安全系统在大规模开放式网络应用中存在的问题，提出了以Agent为本构建移动Agent安全体系的一种新方法，设计了具体的实施方案：Agent注册和Club服务机制．前者引入Agent注册处对Agent代码进行事前验证；后者引入Club服务器为用户提供Agent信息咨询服务．这种方案使移动Agent运行环境可以在保证Agent不对系统造成损害的同时，对特定Agent本身的资源需求进行授权．文中还给出了安全体系的结构和功能，并开发了遵循这一设计方案的原型系统Roamer3．O，说明了该方法的可行性和有效性均优于传统系统．     

The wi‐club filter on 𝒫κ λ

We develop the theory of C_{κ, λ}ⁱ, a strongly normal filter over ??_κ λ for Mahlo κ. We prove a minimality result, showing that any strongly normal filter containing {x ∈ ??_κ λ: |x | = |x ∩ κ | and |x | is inaccessible} also contains C_{κ, λ}ⁱ. We also show that functions can be used to obtain a basis for C_{κ, λ}ⁱ (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
