Rationale, aims and objectives According to an influential taxonomy of varieties uncertainty in health care, existential is a key aspect for patients. Although the term “existential uncertainty” appears across number disciplines research literature, its use diffuse inconsistent. To date there has not been systematic attempt define it. The aim this study generate theoretically-informed conceptua...

The present paper deals with the semantics of all, some and not in English and related languages. Since these semantics imply a logic, it also deals with the logic of quantification in natural language. To the extent that the linguistic findings are universally valid, the results are relevant to the study of human cognition in general. Since standard quantification theory (SQT) replaced Aristot...

Given k ∈ N and a finite group G, it is shown that G is isomorphic to a subgroup of the group of symmetries of some n-cube in such a way that G acts freely on the set of k-faces, if and only if, gcd(k, |G|) = 2s for some non-negative integer s. The proof of this result is existential but does give some ideas on what n could be.

HEX-programs extend ASP by external sources. In this paper, we present domain-specific existential quantifiers on top of HEX-programs, i.e., ASP programs with external access which may introduce new values that also show up in the answer sets. Pure logical existential quantification corresponds to a specific instance of our approach. Programs with existential quantifiers may have infinite groun...

Background: Women and men who have infertility problems, are faced with numerous psychological pressures, including changes in family environment and social networks, sexual problems and challenges of infertility stress which are associated with depression and psychological distress and can result in premature withdrawal of medical infertility treatments and unresolved feelings of loss and grie...

Aging confronts humans with specific existential issues. They frequently cause suffering in old age. Not dealing with or insufficiently dealing with these existential themes may result in crisis, psychological disorders, and illness. By integrating existential themes of aging into the understanding of one's own life, the process of aging contributes to personal maturity.
