Comparative evaluation of molecular methods for the quantitative measure of torquetenovirus (TTV) viremia, the new surrogate marker of immune compete…
2019
Background Torquetenovirus (TTV) viremia is emerging as a promising tool to assess functional immune competence, to predict posttransplant immune-related complications, and eventually to customize immunosuppression. Methods In this study, 327 blood samples were tested using two real-time PCR (rtPCR) assays both targeted to the untranslated region of the TTV genome. The first assay was an in-house rtPCR developed by our group, the second one was the recently marketed TTV R-GENE assay. Results In the validation study, the TTV R-GENE showed good performances in precision and reproducibility, and sensitivity as low as 12 TTV DNA copies/mL, like previously reported for the in-house rtPCR. The Bl…

The Berkeley Innovation Index: A Quantitative Approach to Measure, Track and Forecast Innovation Capability Within Individuals and Organizations
2018
Innovation and entrepreneurship are essential processes for human development, market growth, and technological breakthroughs, and it is vital for economic growth. Despite its importance, innovation is inherently difficult to measure and hence it is almost impossible for an individual or organization to know how they can improve their innovation output or claim that they are great at innovation. This paper presents a novel approach to measure and quantify innovation, called the Berkeley Innovation Index (BII). The BII characterizes and measures innovation capability of an individual or an organization. It builds on the hypothesis that innovation performance depends on the people, culture, a…
Measuring value levers: Experimental and contingent approaches
2014
Abstract This paper compares two alternative methodologies—the experimental–behavioral approach and the contingent approach—for measuring the value that an attribute of a good (product or service) creates for potential customers. In the experimental–behavioral methodology, potential buyers make actual purchase decisions by receiving financial incentives. In the contingent approach, commonplace in marketing research and purchase decisions are hypothetical. A case–control experiment shows that both methodologies discriminate between key and less relevant attributes in purchase decisions, and provide reliable qualitative information on the value of an attribute. Contingent methodologies fail, …
On a Quantitative Measure for Modularity Based on Information Theory
2005
The concept of modularity appears to be crucial for many questions in the field of Artificial Life research. However, there have not been many quantitative measures for modularity that are both general and viable. In this paper we introduce a measure for modularity based on information theory. Due to the generality of the information theory formalism, this measure can be applied to various problems and models; some connections to other formalisms are presented.
Quantitative characterization of antigens using monoclonal antibody reactivities
1993
A multipurpose program that empirically relates antigenic reactivities with monoclonal antibodies (MAbs) to genetic distances is presented. The program uses a set of known genetic pairwise distances to weigh each MAb depending on its capacity to define groups of taxonomically related antigens. This allows highly accurate identification and classification of unknown antigens. Also, the weights obtained constitute a quantitative measure of epitope conservation and can be used for improved vaccine design. © 1993 Oxford University Press.
