This paper defines a new stacked generalization framework in the context of information extraction (IE) from online sources. The proposed setting removes the constraint of applying classifiers at the base-level. A set of IE systems are trained instead to identify relevant fragments within text documents, which differs significantly from the task of classifying candidate text fragments as releva...

The challenge 1 of the BIOVIS 2015 design contest consists in designing an intuitive visual depiction of base pairs binding probabilities for secondary structure of ncRNA. Our representation depicts the potential nucleotide pairs binding using nested concave hulls over the computed MFE ncRNA secondary structure. Thus, it allows to identify regions with a high level of uncertainty in the MFE com...

Clark and Scarf (1960) consider a two-stage inventory system in a finite horizon. They show that echelon base-stock policies are optimal. The optimal base-stock levels can be obtained by solving two sets of recursive, functional equations. Nevertheless, finding the upstream base-stock level is more complex because the functional equation depends on the downstream base-stock level. This paper pr...

In the absence of a single, standard, multipurpose terminology for representing medications, the HL7 Vocabulary Technical Committee has sought to develop a model for such terms in a way that will provide a unified method for representing them and supporting interoperability among various terminology systems. We evaluated the preliminary model by obtaining terms, represented in our model, from t...

The AOCMF Classification Group developed a hierarchical three-level craniomaxillofacial classification system with increasing level of complexity and details. The highest level 1 system distinguish four major anatomical units, including the mandible (code 91), midface (code 92), skull base (code 93), and cranial vault (code 94). This tutorial presents the level 2 and more detailed level 3 syste...

in the present study, the interactions of three different lithium species li+, li3+ and ch3li with several different sites of the most stable tautomers of dna nucleo-bases are presented. this investigation is based on the results of thermochemical properties, quantum theory of atoms in molecules (qtaim) and natural bond orbital (nbo) analysis, obtained at b3lyp/6-311++g(d,p) level of theory. th...

The information ecology perspective [2] helps to understand information spaces in terms of the creation, searching, and use (consumption) of information. An information ecology perspective of Computer-Supported Collaborative Learning (CSCL) environments describes the flow of information into the ecology (who writes notes? how many and when?) and the use of that information (who reads? how many ...

The design of systems-on-chip requires simulation of highly abstracted models, such as SystemC Transaction Level Models (TLM), in addition to traditional register transfer level models. Due to the growing complexity of products, analyzing and understanding the behavior of the corresponding SystemC platforms becomes itself a challenge. Huge code bases are generally written by multiple authors an...

When a candidate drug is likely to become available to prescribers and healthcare policy makers, evaluation of therapeutic progress moves forward in two stages. First, the level of expected therapeutic progress must be established. This first stage requires the determination of therapeutic needs and the comparison of these against the results of the clinical studies that will form the basis of ...

In expert systems, hierarchical reasoning can provide better accuracy and understandability. Here, we develop a method of learning hierarchical knowledge from a case library, in which each training instance is described by low level features and high level concepts (e.g., manifestations and diseases) but not by intermediate concepts (e.g., disease states). Learning intermediate knowledge involv...
