Release of oxidases from the roots of plants

Summary In this paper, we report on the isolation and purification of the oxidase released from the roots ofLactuca sativa seedlings. This is the first time that the release of oxidases from the roots of plants into their rhizosphere has been reported.     

金斑喙凤蝶成虫的交配和取食行为观察

１９９７年￣１９９９年在广西大瑶山对金斑喙凤蝶的成虫交配和取食行为进行观察，结果发现：雌雄成虫交配前快速相互追逐直飞高空达１０００ｍ￣１５００ｍ，然后突然双双俯冲而下；资本时雌雄生殖器相互对接，历时０．５ｈ￣３ｈ；交配后雌成虫取食蜜露，第７天开始产卵，第８天死亡；雄成虫交配后不取食，第５天死亡。     

A Group-Oriented （t,n） Threshold Signature Scheme with Traceable Signers

A group-oriented （t, n） threshold signature scheme employs the cryptographic techniques of secret share, allows any subset of t players out of n players to sign message on behalf of the group and disallows the creation of a valid signature if fewer than t players take part in the signature protocol. In this paper, we proposed a new group-oriented （t, n） threshold signature schemes with traceable signers based on Schnorr signature. The proposed scheme is proved traceable, robust and unforgeable against the ＂static＂ adversary with the discrete logarithm assumption in the random oracle model and existence of broadcast channel. The proofs of the strongest security （existential unforgeability against adaptively chosen message attacks under the discrete logarithm assumption） are provided in the random oracle model.

汉字“半图画体”的表义方式

有一种汉字的"书写变体",针对一部分汉字的某个意义加以半图画化的改造,迎合人在直观上膨胀的视觉需要.此"半图画体"使用范围很窄,表义简单(只能表示或增显原字的一个最常用的义项),书写形式不易规范.它的出现是语言稳健性的认知许可.也是汉字形、义相生的造字思维和汉文化"书画合一"这个审美传统的产物.     

布朗族创世神话的哲学审视

布朗族的创世神话对世界和人类的产生作了描述，认为世界最初由“云”、“雾”组成，爆炸之后产生世界，而人类由神人创造或是由某种具体物质变化生成。具有朴素的、辩证的思想萌芽，体现出原始思维的独特性和认识的直观性。     

Command and control model based on complex information relation integration北大核心CSCD

In order to describe collaborative decision-making process, the command and control model is put forward based on complex information relation integrtion and OODA. The characteristics of individual decision-making are analyzed, the complex information relation is considered as the cause of OODA difficulty to describe collaborative decision-making exactly. From the perspective of armament system of systems combat, the information, data, intelligence and knowledge is defined based on knowledge management and Shannon's entropy theory. The basic element is confirmed and the information flow way is analyzed which in the physical, information, cognitive and social domains. From the perspective of information, the armament system of systems complex networks model framework is put forward based on the idea of using OODA to guide armament system of systems complex networks model design. The data, information, intelligence and knowledge flow is analyzed and the describing meta-model is put forward. Using the reticular structure of OODA to describe collaborative decision-making idea is proposed, the command and control model is put forward based on the idea, the simulating tool ExtendSim is used for simulation analysis and results show that our work offer a reference for innovate command and control thory. ©, 2015, The Journal Agency of Complex Systems and Complexity Science.

Inconsistent idealizations and inferentialism about scientific representation

Inferentialists about scientific representation hold that an apparatus's representing a target system consists in the apparatus allowing “surrogative inferences” about the target. I argue that a serious problem for inferentialism arises from the fact that many scientific theories and models contain internal inconsistencies. Inferentialism, left unamended, implies that inconsistent scientific models have unlimited representational power, since an inconsistency permits any conclusion to be inferred. I consider a number of ways that inferentialists can respond to this challenge before suggesting my own solution. I develop an analogy to exploitable glitches in a game. Even though inconsistent representational apparatuses may in some sense allow for contradictions to be generated within them, doing so violates the intended function of the apparatus's parts and hence violates representational “gameplay”.

羰基硫在TGH催化剂上吸附的研究

用重量法真空吸附装置,在310～420K 和3000～20000Pa 条件下,研究了羰基硫在 TGH 催化剂上的吸附等温线和吸附动力学.非线性回归和模型优选表明,吸附等温线符合 Freundlich 方程;吸附动力学符合管孝男速率方程。研究表明,催化剂上的能量呈不均匀的指数分布,秽基硫在表面进行解离型的不可逆化学吸附,吸附热效应为负值。
