a lognormal -like weight distribution . These results are stable over a large range of parameter values (see Text S2 for details). To investigate the extent to which the different forms of plasticity contribute ...
of the growth time of accretion to the decay time of the exponential distribution of lifetimes. In the MLP scenario, an initial delta function distribution of protostellar seed masses (i.e. a lognormal with zero ...
the lognormal fit (e.g. using the 3σ criterion, where σ is the Poissonian data uncertainty in the considered bin). Fit the rest of the distribution with a PL function . Such an approach rests on the assumption ...
becomes a pure power-law distribution in the limit that the initial lognormal seed distribution has zero variance, i.e. is a delta function . The index of the power law in the differential number per ...
) is small. The lognormal distribution is of the form $$\begin{eqnarray*} \mathcal {P}(s) = {1\over \sqrt{2\pi }\, \sigma _{\rm s}}\exp \left[ -{(s - \mu)^2\over 2\, \sigma _{\rm s}^2}\right], \quad s = \ln ...
an example network with Gaussian weights, we primarily use distributions with exclusively positive support, such as lognormal and gamma, focusing particularly on gamma- distributed synapses for reasons given ...
random variable having a heavy tail with cumulative distribution function (CDF) specified by FY(⋅). We define a random variable X say having a discrete heavy tailed distribution as one specified ...
to galaxy integrated star formation rate histories, drawn from a semi-analytic model grafted on to a dark matter simulation. Both a lognormal functional form and principal component analysis (PCA) approximate ...
of the flare durations is 0.54 d. The distribution of D can be rather well represented by the lognormal function : \begin{equation*} f(x)= \frac{1}{\sqrt{2\pi } \sigma x } {\rm exp} \Bigl [{-\frac{(\ln x-\ln \mu ...
