The Ets transcription factor Spi-C, expressed in B cells and macrophages, is closely related to PU.1 and has the ability to recognize the same DNA consensus sequence. However, the function of Spi-C has yet to be determined. The purpose of this study is to further examine Spi-C activity in B cell development. First, using retroviral vectors to infect PU.1(-/-) fetal liver progenitors, Spi-C was ...

In the early writing on software process improvement (SPI), it was suggested that the group of people responsible for designing and implementing the SPI system should apply the principles of SPI on themselves, making sure their own processes were no less mature than the processes they were trying to improve. Looking at maturity level theory from various literature sources, it seems reasonable t...

Managing a successful Software Process Improvement (SPI) is a challenging issue that many software companies face today. Many companies have invested huge amount of money in improving their software processes. This can be confirmed through several papers that present the results of SPI programs. However, as pointed out by the literature, many of these programs have encountered difficulties to a...

Systematic Literature Review (SLR) is becoming a vital part of present day research in software process improvement (SPI). Nevertheless, there is no available study that provides detail review of the published software process improvement SLRs. Objective: The aim of this article is to classify the SLRs of SPI in order to identify the main research areas covered and evaluate the quality of the p...

Virulence genes located on pathogenicity islands play a crucial role in the pathogenesis of Salmonella enterica infections. Salmonella pathogenicity islands (SPI) contribute to host cell invasion and intracellular pathogenesis. At present, 12 SPI have been described. Although size, structure and function of these SPI, as well as the distribution in Salmonella subspecies and serovars can be mark...

Two deletion-substitution mutations of phage lambda, spi-113 and spi-274, are shown to remove about half of the rightward operator OR. Physiological studies show that spi-113 is still repressible. Thus, the 50 or so nucleotides of OR deleted in this mutant are not absolutely essential for repression. prm-116, which inactivates the promoter essential for the maintenance of lambda repressor synth...

Speaking fast causes several changes in speech prosody. In addition, it can be associated with a decrease intelligibility. this study, prosodic were investigated using common measurements and syllabic prosody index (SPI), novel prominence measure that combines f0, energy duration features. Dynamic long-term functional data analysis (FDA), which the SPI is transformed into form. The possibly dec...
