In this paper we provide a general framework for learning in AL-log, a hybrid language that integrates the description logic ALC and the function-free Horn clausal language Datalog. In this framework inductive hypotheses are represented as constrained Datalog clauses, organized according to the B-subsumption relation, and evaluated against observations by applying coverage relations that depend...

BACKGROUND Joint United Nations Programme on HIV/AIDS (UNAIDS) and Murray et al. have both produced sets of estimates for worldwide HIV incidence, prevalence and mortality. Understanding differences in these estimates can strengthen the interpretation of each. METHODS We describe differences in the two sets of estimates. Where possible, we have drawn on additional published data to which esti...

IIn recent years, policymakers have generally relied on regulatory policies to address financial stability concerns. However, our understanding of these policies and their efficacy in curbing housing prices is limited. In this paper, we examine the impact of three regulatory tools i.e. LTV (loan to value) ratio, reserve requirement rate (RR), and capital adequacy ratio (CAR) on housing price in...

Rud syndrome consists of mental retardation, epilepsy, ictihyosis, dentition and skeleton defect. We report a case of Rud syndrome that have clinical, radiological and biochemical characteristics of rickets. Alteration in epidermal cholestrol metabolism, limited sun exposure or associated defects may explain this condition. All such patients need life – long rickets prophylaxis with vitamin D s...

Various methods for transfecting molecules such as DNA, RNA, proteins, or drugs with high efficiency and low toxicity have been implemented and optimized for many different cell types. These include widely used techniques such as chemical transfection (lipid-based techniques), the use of viral vectors and electroporation. To date, laserassisted transfection of cells has relied on cumbersome Arg...

It has come to our attention that the work of Yuan et al. [1] is being represented as definitive regarding the existence of a particular nonstrange, isoscalar, spin three dibaryon, d * , which we [2] , among others [3, 4, 5, 6, 8] , have proposed exists. We therefore wish to comment on this paper and its relation to ours and those of others. In our work [2] , the d * dibaryon is constructed in ...

The "neighborhood effects" literature, as currently constructed in epidemiology, would benefit from critical attention to the following four issues: 1) use of appropriate measurement tools and methods for neighborhood environments; 2) theoretical or conceptual guidance as to the aspects of residential environments most salient to human health (both within and across health endpoints); 3) the sc...
