Incomplete Information research is quite mature when it comes to so called existential nulls, where an existential null is a value stored in the database, representing an unknown object. For some reason universal nulls, that is, values representing all possible objects, have received almost no attention. We remedy the situation in this paper, by showing that a suitable finite representation mec...

In Vitro Tumor Models The success of personalized cancer therapy hinges on a timely clinical decision and preclinical model that can recapitulate tumor stromal heterogeneity for clinically relevant drug profiling. article 2202279, Eliza Li Shan Fong co-workers review how by transcending the existential reductionist approaches, bioengineered patient-derived explant (PDE) models truly replicate f...

UNLABELLED To review adverse events of intensive, clinical holistic medicine (CHM) as it is practiced in holistic body-psychotherapy in England and Germany. Gerda Boyesen's "biodynamic body-psychotherapy" (BBP) is an intensive type of holistic mind-body medicine used by Boyesen at two centers. METHODS About 13,500 patients were treated during 1985-2005 period and studied for side effects and ...

OBJECTIVES This article presents a detailed idiographic analysis of patients' experience of first-episode depression. DESIGN This is a qualitative interview study using interpretative phenomenological analysis (IPA). METHODS Semi-structured interviews were carried out with a purposive sample of seven patients presenting to a mental health service in London, UK with symptoms of first-episode...

We prove that the terms of the derived series of a free solvable group are definable by existential formulae. We use this result to prove some ‘model theoretic’ results about free solvable groups. For example, we prove that if Hilbert’s 10th problem has a negative answer for the field of the rationals, then the universal theory of a noncyclic free solvable group of class > 3 is undecidable. @ 1...

Since Al-Riyami and Paterson presented certificateless cryptography, many certificateless schemes have been proposed for different purposes. In this paper, we present a certificateless group oriented signature scheme based on bilinear pairing. In our scheme, only the members in the same group with the signer can independently verify the signature. We prove the signature scheme is existential un...

This study aimed to examine the stories of 25 prophets mentioned in Qur'an within framework existential theory. The research has been studied on associating and their with concepts While life was encountered existentially positive theory, no relationship could be established negative concepts. Knowing that holy book Islam, Qur'an, can associated theory is important because it beneficial therapy...

On every set A there is a rigid binary relation i.e. such a relation R ⊆ A × A that there is no homomorphism (A,R) → (A,R) except the identity (Vopěnka et al. [1965]). We prove that for each infinite cardinal number κ if card A ≤ 2 then there exists a relation R ⊆ A×A with the following property ∀ x 6=y ∃ {x}⊆A(x,y)⊆A cardA(x,y)≤κ ∀ f :A(x,y)→A f(x)=y f is not a homomorphism of R which implies ...

In this paper we introduce a parameterized generalization of the well known superimposed codes. We give algorithms for their construction and provide non-existential results. We apply our new combinatorial structures to the e5cient solution of new group testing problems and access coordination issues in multiple access channels. c © 2003 Elsevier B.V.

Existential anxiety is hypothesized to be a core human issue in a great deal of theoretical and philosophical writing. Fostering the empirical understanding of the expression of these concerns may be a valuable addition to the psychological literature on exposure to trauma. The purpose of this study was to test theoretical predictions about the association between different facets of existentia...
