In the first part of this paper, we present a framework for enriching arbitrary upper or domain-specific ontologies with a concept of time. To do so, we need the notion of a time slice. Contrary to other approaches, we directly interpret the original entities as time slices in order to (i) avoid a duplication of the original ontology and (ii) to prevent a knowledge engineer from ontology rewrit...

We show that for a commutative quantale V every functor Set −→ V -cat has an enriched leftKan extension. As a consequence, coalgebras over Set are subsumed by coalgebras over V -cat. Moreover, one can build functors on V -cat by equipping Set-functors with a metric. 1998 ACM Subject Classification F.4.1 Mathematical Logic

We prove Manin’s conjecture for a split singular quartic del Pezzo surface with singularity type 2A1 and eight lines. This is achieved by equipping the surface with a conic bundle structure. To handle the sum over the family of conics, we prove a result of independent interest on a certain restricted divisor problem for four binary linear forms.

Many children who require hospitalization are admitted to community hospitals that are more accessible for families and their primary care physicians but vary substantially in their pediatric resources. The intent of this clinical report is to provide basic guidelines for furnishing and equipping a pediatric area in a community hospital.

School counsellors are often the first point of contact when people are concerned about a young person’s eating. The Children’s Hospital at Westmead Eating Disorders Program in collaboration with The Children’s Hospital School has developed an eating disorder education program for school counsellors. The aim of this program is to equip school counsellors with general knowledge about eating diso...

Edi tor ’s Note : NEHA strives to provide up-to-date and relevant information on environmental health and to build partnerships in the profession. In pursuit of these goals, we feature a column from the Environmental Health Services Branch (EHSB) of the Centers for Disease Control and Prevention (CDC) in every issue of the Journal. In this column, EHSB and guest authors from across CDC will hig...

OBJECTIVE To assess the actual impact on coronary mortality of equipping ambulances with defibrillators. DESIGN Retrospective analysis of routine medical and legal records of all those who had a cardiac arrest attributed to coronary heart disease occurring outside hospital in a defined population before and after the introduction of Heartstart. SETTING City of Glasgow, North of the River Cl...
