A new approach to semantics, based on ordered Banach spaces, is proposed. The Banach spaces semantics arises as a generalization of the four particular cases: the Giles' approach to belief structures, its generalization to the non-Boolean case, and “fuzzy extensions” of Boolean as well as of non-Boolean semantics. 相似文献

The term reflex is used in a broad sense. Reflexes having a drive component are denoted as higher. Four types of higher reflexes are distinguished: avoidance, escape approach and consummately. Each of these reflexes has a different drive component. The result of the reflex is a removal of the corresponding drive. For this purpose three different strategies are used. Complex higher reflexes are usually programmed and occur frequently in a chain form. A given function of an organism is performed by a system of reflexes controlled by one or more drives. 相似文献

Professor Ryszard Wójcicki once asked whether the degree of maximality of the consequence operationC determined by the theorems of the intuitionistic propositional logic and the detachment rule for the implication connective is equal to \(2^{2^\aleph 0} \) ? The aim of the present paper is to give the affirmative answer to the question. More exactly, it is proved here that the degree of maximality ofC Ψ — theΨ — fragment ofC, is equal to \(2^{2^\aleph 0} \) , for every such that → εΨ. 相似文献

We propose a new schema for the deduction theorem and prove that the deductive system S of a prepositional logic L fulfills the proposed schema if and only if there exists a finite set A(p, q) of propositional formulae involving only prepositional letters p and q such that A(p, p) L and p, A(p, q) s

We say that a semantical function is correlated with a syntactical function F iff for any structure A and any sentence we have A F
A .It is proved that for a syntactical function F there is a semantical function correlated with F iff F preserves propositional connectives up to logical equivalence. For a semantical function there is a syntactical function F correlated with iff for any finitely axiomatizable class X the class
–1X is also finitely axiomatizable (i.e. iff is continuous in model class topology). 相似文献

Using ideas from Murskii [3], Tokarz [4] and Wroński [7] we construct some strongly finite consequence operation having 2%0 standard strengthenings. In this way we give the affirmative answer to the following question, stated in Tokarz [4]: are there strongly finite logics with the degree of maximality greater than ?0? 相似文献

The use of experimental animals, mostly rodents, in biomedical research and especially in oncology and immunology should be
acknowledged with respect, recognizing the contribution of animal experimentation in the fascinating scientific progress in
these disciplines of research. It is an obligation of the investigator to justify the scientific and ethical aspects of each
study requiring the use of animals. The international guiding principles for using animals in biomedical research are well
defined and have been distributed worldwide by the International Council for Laboratory Animal Science (ICLAS) since 1956,
when this Organization was founded. In Poland the ICLAS philosophy and principles are highly respected and were implemented
firstly by the members of the Commission on Biology of Experimental Animals appointed in 1962 by the Department of Medical
Science of the Polish Academy of Science in Warsaw. Animal Protection Acts, first proclaimed in 1928 were gradually modified
and improved. Actual legislation (enacted in 1997, 2003 and 2005) is consistent with EU Directives (86/609/EEC) and follows
the internationally recommended principles that include ICLAS guidelines concerning animal welfare and care condition in biomedical
research. The problem of “alternative methods” is briefly discussed.

Conduct of Basic and Clinical Research’, held in Warsaw, Poland, 3–4 June 2005.
The author is the National Representative of Polish Academy of Science to the International Council for Laboratory Animal
Science (ICLAS) and a Member of the ICLAS Governing Board. 相似文献
