Sensor databases extend database technology to query and monitor the physical world as a highly distributed database. In this paper we consider a Data Transmission Algebra (DTA) that allows a query optimizer to utilize lower layer communication protocols in scheduling sensor database queries. By being able to determine the order in which data are processed at sensor nodes and transmitted betwee...

Cross-domain analogies are a powerful method for learning new domains. This paper extends the Domain Transfer via Analogy (DTA) method with the idea of persistent mappings, correspondences between domains that are incrementally built up as a system gains experience with a new domain. We evaluate DTA plus persistent mappings by learning three domains (rotational mechanics, electricity, and heat)...

In 1996, shortly after the founding of The Cochrane Collaboration, leading figures in test evaluation research established a Methods Group to focus on the relatively new and rapidly evolving methods for the systematic review of studies of diagnostic tests. Seven years later, the Collaboration decided it was time to develop a publication format and methodology for Diagnostic Test Accuracy (DTA) ...

A data tree is an unranked ordered tree where each node carries a label from a finite alphabet and a datum from some infinite domain. We consider the two variable first order logic FO(<,+1,∼) over data trees. Here +1 refers to the child and the next sibling relations while < refers to the descendant and following sibling relations. Moreover, ∼ is a binary predicate testing data equality. We exh...

Diphtheria toxin is a single-chain protein toxin that invades human cells by receptor-mediated endocytosis. In acidic endosomes, its translocation domain inserts into endosomal membranes and facilitates the transport of the catalytic domain (DTA) from endosomal lumen into the host cell cytosol. Here, DTA ADP-ribosylates elongation factor 2 inhibits protein synthesis and leads to cell death. The...

Current Text-to-Speech systems, commonly used for document accessibility, do not include an effective and standard acoustic provision of the visual typographic cues embedded in them. In this work, we first introduce the text signals (i.e. the writing devices that emphasize aspects of a text’s content or structure) along with an appropriate architecture for the structure of documents as well as ...

Thoracic endovascular aortic repair (TEVAR) for descending thoracic aortic aneurysms (DTAs) was first reported by Dake et al1 in 1994. The advent of TEVAR was clinically relevant because open DTA repair had long been associated with operative mortality rates ranging from 5% to 7% at centers of excellence2,3 to as high as 20% to 22% in real-world practice.4,5 The favorable results6 of TEVAR with...

S urgical treatment of aortic arch aneurysms has been challenging. These aneurysms are usually treated with open surgical repair that requires cardiopulmonary bypass (CPB) and hypothermic circulatory arrest (HCA). Furthermore, in cases of aneurysms involving both the aortic arch and the descending thoracic aorta (DTA) extensive surgical incisions or staged procedures are often necessary, increa...

Diagnostic test accuracy (DTA) studies on fine-needle aspiration cytology (FNAC) often show considerable variability in diagnostic accuracy between study centers. Many factors affect the accuracy of FNAC. A complete description of the testing parameters would help make valid comparisons between studies and determine causes of performance variation. We investigated the manner in which test condi...
