Quantitative analysis of software systems is being recognized as an important part of the software development process. In particular, performance analysis can be particularly helpful in identifying possible bottlenecks during the early stages of the software development life cycle. Early identification of problems is particularly desirable as the costs of changing the design are much higher th...

Much of the research to date on street children has taken the form of largely quantitative surveys which have sought to establish numbers of street children, the reasons for their presence on the streets, their demographic and household characteristics, and their survival and criminal activities. A constant temptation in broadly quantitative research of this nature is to formulate a ‘composite ...

Rhesus monkey rhadinovirus (RRV) and Kaposi's sarcoma-associated herpesvirus (KSHV; also called human herpesvirus 8) belong to the gamma-2 grouping of herpesviruses. RRV and KSHV share a high degree of sequence similarity, and their genomes are organized in a similar fashion. RRV serves as an excellent animal model system to study the gamma herpesvirus life cycle both in vitro and in vivo. We h...

Directed cell motility is preceded by cell polarization-development of a front-rear asymmetry of the cytoskeleton and the cell shape. Extensive studies implicated complex spatial-temporal feedbacks between multiple signaling pathways in establishing cell polarity, yet physical mechanisms of this phenomenon remain elusive. Based on observations of lamellipodial fragments of fish keratocyte cells...

The capability of retrieving spectral information from line shapes recorded by two-tone frequency-modulation spectroscopy (TTFMS) is investigated. A TTFMS theory accounting for dispersion and nonlinear distortion of diode laser frequency modulation response is presented. The adequacy of the theory for a detailed modeling of line shapes recorded with high resolution is examined. An extensive err...
