This study after reviewing  construction methods of generators in Archimedean copulas (AC),  proposes several useful lemmas related with generators of AC. Then a new trigonometric Archimedean family will be shown which is based on cotangent function. The generated new family is able to model the low dependence structures.

Aim: The aim of this systematic analysis was to assess the prevalence dentinal microcracks at various levels (3, 6, and 9 mm from apex) after using instruments made with conventional, R-Phase, M-Wire NiTi alloys SAF system. Materials Methods: Electronic searches were conducted in databases Embase, Cochrane Library, Scopus, PubMed, Web Science. To arrange search methods, “MeSH” terms and/or keyw...

BACKGROUND Psoriasis is a chronic inflammatory skin disease with a genetic basis. Its ill-defined causes make it difficult to diagnose. This study aims to develop a diagnostic checklist for psoriasis classification in the context of traditional Chinese medicine. METHODS A Delphi study was conducted with three rounds by a panel of 16 dermatology experts to develop a checklist for traditional C...

Is it possible to talk about God without either misrepresentation or failing to assert anything of significance? The article begins by reviewing how, in attempting to answer this question, traditional theories of religious language have failed to sidestep both potential pitfalls adequately. After arguing that recently developed theories of metaphor seem better able to shed light on the nature o...

This article focuses on an aspect of traditional instruction — the form-only activities commonly called "drills," "mechanical practice," or "pattern practice." The authors first distinguish language as an internalized system from language as a productive skill and review the nature of mechanical pratice. They contend that despite claims made about communicative language teaching and its goals, ...

During the past three years, central banks have faced challenges that few foresaw during the period known as the Great Moderation. During the crisis, central banks have responded with traditional interest rate tools, been forced to deal with the zero lower bound on nominal interest rates, and expanded the scope of their lender of last resort function. In addition, quantitative easing and credit...

We consider the problem of storing and searching a large state space obtained from a high-level model such as a queueing network or a Petri net. After reviewing the traditional technique based on a single search tree, we demonstrate how an approach based on multiple levels of search trees offers advantages in both memory and execution complexity. Further execution time improvements are obtained...

Virtual communities are the uppermost communication spaces and channels for online word-of-mouth. And opinion leaders are the most important group for enterprises’ word-of-mouth communication. As enterprises are engaged in online word-of-mouth marketing activities, the key is to find out the opinion leaders in virtual communities. In this paper, after affirming the effects of opinion leaders an...

This paper reports on the conceptual development of an architecture for building intelligent fuzzy decision support systems (IFDSS). The changing nature of decision making today’s fast paced environment calls for new techniques for dealing with both quantitative and qualitative components of decision making. Soft computing tools like fuzzy reasoning offer much promise in this area. After review...

After reviewing the evidence for status quo maintenance (SQM), I consider how to reconcile SQM with traditional consumer theory. Behavioural economists usually let agents’ preferences change as a function of their endowments, treating the same person with different endowments as a set of distinct agents. Many properties of preferences then become immune to empirical test and it becomes impossib...
