Abstract We use material-distribution-based topology optimization to design a three-port frequency dividing multiplexer at microwave frequencies. That is, by placing good electric conductor inside the domain, we aim passive device that splits incoming signal’s frequencies into two bands and transmits them their respective output ports. The Helmholtz equation models time-harmonic wave propagatio...
Mature neocortical layers all derive from the cortical plate (CP), a transient zone in the dorsal telencephalon into which young neurons are continuously delivered. To understand cytogenetic and histogenetic events that trigger the emergence of the CP, we have used a slice culture technique. Most divisions at the ventricular surface generated paired cycling daughters (P/P divisions) and the maj...
lentiviral vectors (lvs) are useful vehicle for genetransfer to dividing and non-dividing cells and genetic manipulations. however, the use of lentiviruses in studies requires an accurate titration technique.quantitative real-time pcr (qpcr) is a sensitive technique for the indication and quantitation of retrovirals particles. in this study, we used the qpcr for lentiviral vector titeration. th...
