Abstract Recent development of path integral matching techniques based on the covariant derivative expansion has made manifest a universal structure of one-loop effective Lagrangians. The universal terms can be computed once and for all to serve as a reference for one-loop matching calculations and to ease their automation. Here we present the fermionic universal one-loop effective action (UOLEA), resulting from integrating out heavy fermions (Dirac or Majorana) with scalar, pseudo-scalar, vector and axial-vector couplings. We also clarify the relation of the new terms computed here to terms previously computed in the literature and those that remain to complete the UOLEA. Our results can be readily used to efficiently obtain analytical expressions for effective operators arising from heavy fermion loops [13].

Log Normal Distribution

We investigate the Japanese personal income distribution in the high income range over the 112 years (1887–1998), and that in the middle income range over the 44 years (1955–1998). It is observed that the distribution pattern of the log-normal with power law tail is the universal structure. However, the indexes specifying the distribution differ from year to year. One of the index characterizing the distribution is the mean value of the log-normal distribution; the mean income in the middle income range. It is found that this value correlates linearly with the gross domestic product (GDP). To clarify the temporal change of the equality or inequality of the distribution, we analyze Pareto and Gibrat indexes, which characterize the distribution in the high income range and that in the middle income range, respectively. It is found for some years that there is no correlation between the high income and the middle income. It is also shown that the mean value of Pareto index equals to 2, and the change of this index is effected by the change of the asset price. From these analysis, we derive four constraints that must be satisfied by mathematical models.

By using on-orbit replacement and assembly technology, some fresh ideas and methods for the design, produce and application of spacecraft were put forward. Universal structure is one of the most basic requirements of On-Orbit replacement, assembly. Module structure must obey the rules of the Operationally Responsive Space (ORS). According to the degree of spacecraft module division, two module structures were proposed, and the complex structure was analyzed to verify the correctness of it.

Although usually applied in the field of personality psychology, in the last decade there were attempts of applying the lexical paradigm in the studies social attitudes studies. One of those attempts was made by Saucier (2000), who included and analyzed all the words ending with the suffix ?-ism?. The product of this analyze is a two-form instrument called "Survey of Dictionary-Based Isms (SDI)", with its long, 40-item version, and brief, 28-item version. This instrument measures four main dimensions of basic social attitudes: alphaisms (traditional and religious sources of authority), betaisms (dismissing political correctness), gammaisms (believing in Western democracy) and deltaisms (personal spirituality). Until now, this instrument was only used in English-speaking area, and therefore the objective of this research was evaluation and validation of Saucier?s basic structure of social attitudes model in the Serbian-speaking area. In this research, conducted on the sample of 253 participants, both sexes, average age of 39.3 years (SD=14.9), a slightly shortened version of Saucier?s 24-item questionnaire was used. The results of this study contribute to the hypothesis of a universal structure of basic social attitudes: the factor analysis extracted four factors, which correlate from moderate to high level with the original dimensions. However, the structure and content of the factors pointed to a strong cultural influence on the forming and shaping the basic social attitudes. Practically, only the first factor, Religiosity, is a full replication of the original alpha factor. Other items built the factors somewhat different from the original: Hedonism, Rational Spirituality and Nationalism. The results show a better fitness of the model obtained in this study for the Serbian-speaking area compared to the original one.

This article studies the formalized lexicographic description of the archaeological terminology and aims to develop its basis — the universal dictionary entry structure. The authors prove the need for the unified description of an archaeological term in dictionaries and terminological databases. The comparative analysis of the dictionary entry structures of contemporary archaeological dictionaries and term databases has shown that the unified principles for the formalized description of an archaeological object have not yet been developed. Thus, the archaeological dictionaries, as well as the term databases, do not have the unified structure of the dictionary entry. This paper describes the systematic development of the universal structure of the dictionary entry for the archaeological term. The source of the term material was the most complete contemporary terminological dictionary — “The Dictionary of Archaeological Ceramics” by Yu. G. Kokorina (2017). As a result of the logical-conceptual and definitional analysis of the archaeological term descriptions, the authors have proposed 15 linguistic and conceptual parameters: etymology, synonyms, pragmatic parameter, shape, function, constructive parameter, obligatory structural elements, metric parameter, degree of the metric parameter manifestation, proportions, quantitative parameter, cultural-geographical parameter, and construction material. The universal character of these parameters is supposed to ensure the development of the formalized dictionary entry structure of the archaeological term. The proposed all inclusive dictionary entry structure of the archaeological term can become the foundation for the formalized lexicographic description of archaeological terminology both in dictionaries and in automated databases.

Straipsnio tikslas yra atskleisti Vakarų filosofijos tradicijoje savitai įsitvirtinusios patyrimo struktūros, įvardijamos pakartojimu, nihilistinę prasmę. Šioje hermeneutinėje analizėje, viena vertus, re­miamasi tam tikra nihilizmo samprata, numatančia du nihilizmo teorinius modelius – nihilizmą, parem­tą Überwindung teorija, ir nihilizmą, paremtą différance idėja. Kita vertus, remiamasi tam tikru („onto-teologiniu“) pretekstu Vakarų mąstymo tradicijoje atpažįstant pakartojimo struktūrą – Pauliaus Laiško efeziečiams Ef. I, 10 teksto fragmentu, laikomu paradigmine pakartojimo struktūros išsklaida. Herme­neutinė analizė projektuojama į Kierkegaardo ir Agambeno filosofiją, atskirus jų mąstyme atpažįstamus pakartojimo invariantus atskleidžiant kaip minėto Pauliaus Laiško fragmento eksplozijos atvejus. Ke­liamas klausimas, kas yra pakartojimas, kur slypi jo negatyvumas ir kaip pasirodo jo nihilistinė prasmė? Kaip šioje negatyvumo ir nihilizmo atskleistyje „tarpininkauja“ différance? Straipsnyje parodoma, jog skirtis kaip neigimo judesys, atstovaujantis nihilistinei logikai, gali būti traktuojamas ir vien formaliai, ir realiai. Skirties kaip realaus neigimo traktavimas Kierkegaardo ir Agambeno mąstyme atitinka pačios patirties struktūros – pakartojimo – ontologinį (tikrovišką) įšaknytumą.Pagrindiniai žodžiai: pakartojimas, nihilizmas, différance, negatyvumas, laikasPakartojimas ir nihilizmasRita Šerpytytė   AbstractThe purpose of this article is to reveal the nihilistic sense of an experiential structure, which has been distinctively rooted in Western philosophical tradition. On the one hand, this hermeneutical analysis will be based on a certain conception of nihilism presupposing two theoretical models of nihilism – nihilism, which refers to the theory of Überwindung, and nihilism associated with the idea of différance. On the other hand, it builds upon a certain (the so-called “onto-theological”) pretext, which might be used for recognition of the structure of repetition in Western tradition of thinking, – i.e. the fragment of a text from St. Paul’s Letter to the Ephesians Eph. I, 10 – the paradigmatic passage proposing this universal structure of repetition. Focused both on philosophy of Kierkegaard and Agamben, hermeneutical analysis will aim to disclose the separate invariants of such repetition as cases of explosion of the mentioned text fragment. The question is raised – what is repetition? Where does its negativity lie? How does its nihilistic sense appear? How does the différance mediate in this process of revealing of negativity and nihilism? The article argues that difference, as a motion of negation representing nihilistic logic, can be treated both in merely formal and in a realistic way. The treating of différance as real denying in Kierkegaard’s and Agamben’s thinking corresponds to the ontological rootedness of the very structure of experience – repetition.Keywords: repetition, nihilism, différance, negativity, time
