We show that the complement of a subanalytic set defined by real analytic functions from any subalgebra closed under differentiation is a subanalytic set defined by the functions from the same subalgebra. This result has an equivalent formulation in logic: Consider an expression built from functions as above using equalities and inequalities as well as existential and universal quantifiers. Suc...

PURPOSE/OBJECTIVE To explore the meanings assigned to the experience of receiving chemotherapy. DESIGN Descriptive exploratory. SETTING An oncology outpatient clinic in a university hospital in Montreal, Quebec, Canada. SAMPLE Ten women with breast cancer who experienced chemotherapy for the first time. METHODS Semistructured interview using a grounded theory approach. FINDINGS Women ...

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...

Background and Aim: Breast cancer is one of the most common cancers in Iran. The aim of this study was to assess the effectiveness of existential-humanistic therapy in self-acceptance and marital satisfaction in women with breast cancer. Materials and Methods: This was a quasi-experimental study with a pre-test, post-test and follow-up design with a control group. The statistical population wa...

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...

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.

Existential rules (also known as Datalog± or tuplegenerating dependencies) have been intensively studied in recent years as a prominent formalism in knowledge representation and database systems. We consider them here as a querying formalism, extending classical Datalog, the language of deductive databases. It is well known that the classes of databases recognized by (Boolean) existential rule ...
