Because of, well established relationship between seasonal variability and diseases dynamism we embarked here in evaluating recurrently diagnosed at Korhogo General Hospital Northern Côte d’Ivoire from 2014 to 2018. For this purpose, clinical data with regard 1707 patients were collected clusterized 25 cases. Data have been submitted multivariate computational statistical survey the...

With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of ...

After a great deal of initial promise and enthusiasm, evolutionary art seems to have hit a premature and disappointing plateau. This paper proposes a difficult but necessary program for the advancement of evolutionary art. First two significant problems are discussed. The first is the problem of creating aesthetic fitness functions that would allow evolutionary art systems to execute unattended...

The pace of business dynamism as measured by indicators such as job reallocation has declined in recent decades in the U.S., and theory suggests that this may have implications for productivity. The declining dynamism in sectors like Retail Trade disproportionately accounted for these trends in the 1980s and 1990s, and was productivity enhancing. In contrast, the pace of reallocation in High-Te...

Due to globalization and environmental challenges, there is a growing interest in adopting collaborative technologies to support distributed virtual enterprises to work as virtual teams, reducing time, cost and need for travel. This paper presents the approach taken by the CoSpaces project [1] in developing a collaborative technology platform for distributed engineering organizations. In partic...

This article uses a recently presented abstract, tunable Boolean regulatory network model to further explore aspects of mobile DNA, such as transposons. The significant role of mobile DNA in the evolution of natural systems is becoming increasingly clear. This article shows how dynamically controlling network node connectivity and function via transposon-inspired mechanisms can be selected for ...

We document empirical evidence linking regional growth in the United States over the last 25 years with entrepreneurial activity, or ‘business dynamism’. The main data source is the Business Dynamics Statistics (BDS) released by the US Census Bureau. We uncover a new stylised fact: across US states, it is not the level but rather the change in business entry rate that has a significant positive...

This study explores the fundamental tension between too little and too much structure. Observed in multiple streams of research, this tension is associated with the tradeoff between efficiency and flexibility that is central in dynamic markets. Using the strengths of simulation to confirm internal validity and to elaborate theory through virtual experiments, we examine the relationship between ...
