Lis1 and Ndel1 influence the timing of nuclear envelope breakdown in neural stem cells
Lis1 and Ndel1 are essential for animal development. They interact directly with one another and with cytoplasmic dynein. The developing brain is especially sensitive to reduced Lis1 or Ndel1 levels, as both proteins influence spindle orientation, neural cell fate decisions, and neuronal migration. We report here that Lis1 and Ndel1 reduction in a mitotic cell line impairs prophase nuclear enve...
متن کاملDependence of laser-induced breakdown spectroscopy results on pulse energies and timing parameters using soil simulants.
The dependence of some LIBS detection capabilities on lower pulse energies (<100 mJ) and timing parameters were examined using synthetic silicate samples. These samples were used as simulants for soil and contained minor and trace elements commonly found in soil at a wide range of concentrations. For this study, over 100 calibration curves were prepared using different pulse energies and timing...
متن کاملThe Study of Breakdown Voltages for Triggered Spark Gap Switches
This study explains the breakdown mechanism in different triggered spark gap switches. Two different trigger electrode configurations are tested for the switch predischarge operation in a nitrogen laser circuit. The behavior of the breakdown voltage, when a trigger pulse is applied to the trigger electrode, is investigated, and the results are reported. Based on the experimental measurements ne...
متن کاملDetecting the Breakdown of Traffic
Timely traffic prediction is important in advanced traffic management systems. Observing traffic flow, we find repetitive or regular behavior over time. By taking advantage of tools in frequency domain analysis, this paper proposes a new criterion function that can detect the onset of congestion. It is found that the changing rate of the cross-correlation between density dynamics and flow rate ...
متن کاملBreakdown analysis
It is a widely-supported tenet in human-computer interaction that the meaningful unit of analysis is not the technical device alone, but the technical device together with the person interacting with it; the reason is that what is a relevant property of a technology is only understandable with respect to the specific goals and resources activated during its usage. This basic reflection should a...
