By extending the method developed by Peierls, the optimal values of activation and counting time have been calculated, so as to give the minimum error in the exponential decay constant. Both single- and multi-cycle experiments have been considered, for various ratios of background activity to ...

a is interpreted as the initial number of nuclei, b is the decay constant, x is time, and y is the number of remaining nuclei after a specific amount of time passes. If two decay modes exist, then you must use the two-term exponential model. For the second decay mode, you add ...
The cdf of the exponential distribution is p=F(x∣u)=x∫01μe−tμdt=1−e−xμ. The resultpis the probability that a single observation from the exponential distribution with meanμfalls in the interval[0,x]. A common alternative parameterization of the exponential distribution is to ...
Either μnet=μrep=0 (i.e., there are no cells dividing) or μnet=0 and μrep<0 (cell mass concentration is constant while the number of viable cells is decreasing). However, there will necessarily be a change in cell mass due to the maintenance of life. This change will be ...

Linear growth happens at the same rate of change. Every increase in X would bring about the same increase in Y. It is constant. With exponential growth there is a constant multiplier, so the growth rate is changing. The Bottom Line
x = 1:5; lambda1 = exppdf(x,2)./(1-expcdf(x,2)) lambda1 =1×50.5000 0.5000 0.5000 0.5000 0.5000 The hazard function (instantaneous rate of failure to survival) of the exponential distribution is constant and always equals1/mu. This constant is often denoted by λ. ...
Our bound for the Erdős-Ginzburg-Ziv constant relies on the more general notion of the partition rank, as defined in [14], which allows us to handle the indicator tensor that appears when we force the variables to be distinct. The slice rank method has seen numerous applications, such ...
