Beyond the gain exponent: Effect of damping, scale length, and speckle length on stimulated scatter.
Three-dimensional wave propagation simulations and experiments show that the gain exponent, an often used metric to assess the likelihood of stimulated Brillouin scatter, is insufficient and must be augmented with another parameter, Nr, the ratio of the resonance length, Lres, to the laser speckle length. The damping rate of ion acoustic waves, ν, and thus Lres, which is proportional to ν, are ...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
colonialism is an important factor in cultural production and many of cultural constructs all over the world. english and english language teaching are at the center of the contemporary world. postcolonial literature, the genre achebe exercised, is a kind of historical text which has become central to different debates and criticisms. in this thesis, different elements related to the colonial...
BACKGROUND Liver stiffness measurement (LSM) using transient elastography (FibroScan®) can assess liver fibrosis noninvasively. This study investigated whether LSM can predict the development of liver-related events (LREs) in chronic hepatitis B (CHB) patients showing histologically advanced liver fibrosis. METHODS Between March 2006 and April 2010, 128 CHB patients with who underwent LSM and...
Transcription factors are common targets of epigenetic inactivation in human cancer. Promoter hypermethylation and subsequent silencing of transcription factors can lead to further deregulation of their targets. In this study, we explored the potential epigenetic deregulation in cancer of Ikaros family genes, which code for essential transcription factors in cell differentiation and exhibit gen...
the aim of this study was to determine the incidence and causes of fever as a major problem contributing to transplantation related mortality among patients undergoing hematopoietic stem cell transplantation (hsct) and evaluation of antibiotic use, according to reliable guidelines.we retrospectively reviewed hospital records of 195 adult patients who underwent hsct between 2009-2011 at hematolo...
Despite the completion of the Human Genome Project, we are still far from understanding the molecular events underlying epigenetic change in cancer. Cancer is a disease of the DNA with both genetic and epigenetic changes contributing to changes in gene expression. Epigenetics involves the interplay between DNA methylation, histone modifications and expression of non-coding RNAs in the regulatio...
