By synthesising data and evidence, mathematical models can be used to identify areas of greater uncertainty or influence. They can also estimate the under-reporting of incidence in an outbreak; epidemics of meningitis have occurred in the African meningitis belt for more than 100 years but, whilst...
In Fig.2, we compare the contribution of different phonon modes toτsandτp. First, we find that at a very lowT- 4 K, only acoustic modes (A1-A3) contribute to spin and carrier relaxation. This is simply because the optical phonons are not excited at such lowT(correspondingkBT ~...
These allow us to predict intrinsic spin lifetimes as an upper bound for experiments, identify the dominant spin relaxation pathways, and evaluate the dependence on temperature, external fields, carrier density, and impurities. We find that the Fröhlich interaction that dominates carrier relaxation ...

Since the brain was found to be somehow flexible, plastic, researchers worldwide have been trying to comprehend its fundamentals to better understand the brain itself, make predictions, disentangle the neurobiology of brain diseases, and finally propose up-to-date treatments. Neuroplasticity is simple...
To use this, I first enter the number whose factorial is being taken. Then I open the probability menu, select the!entry, and then hitenter. The calculator returns the value of the factorial. On your calculator, look for a!button (maybe as a second function) or anx!button, or else ch...
The ability of a restriction enzyme to find a single site by linear diffusion in the supercoiled plasmid is also presumed to be different than for any of the sites on a linear substrate. Although it is not common, some enzymes exhibit differences in their ability to cut supercoiled DNA ...
When looking at the mean effects of the different social stressor constructs, we can also see a variety of effects indicated by a significant amount of heterogeneity; however, while statistically significant, the differences between effect sizes are not very large. Lack of justice shows the stronges...
the number of hollow-dependent arboreal species was not affected. While the wildfires significantly reduced hollow abundance, we did not find significant effects on hollow occurrence. Fires altered the relationship between tree size and hollow occurrence expressed as a change in the probability of hollo...
While these approaches do not provide full answers to the question, they indicate that the line-drawing ques- tion should not be dismissed too hastily. The third step investigates whether the line-drawing problem can find its solution in the concept of suffering. In particu- lar, I ...
