During the early stages of an epidemic, a large proportion of the population remains susceptible to the virus, and if the spread of the virus is left uninhibited by changes in policies or behaviour, exponential growth continues until the fraction of the susceptible population decreases meaningfully11...
The dot-dashed lines denote fitting curves of the exponential function A = A0exp(−πf0t/Q), where A0 is the initial amplitude, f0 is the free oscillation frequency and t is the time. Source data Extended Data Fig. 3 Schematic diagram of the source masses. a, b, In the TOS...
We limit ourselves for the present to conditions of thermal equilibrium, that is, to a subclass of all the phenomena of nature. The laws of mechanics which apply just to thermal equilibrium are called statistical mechanics, and in this section we want to become acquainted with some of the cen...
Thus, the choice of the number of exponential decay terms is arbitrary if justified only by the goodness of fit. In this work the stretched-exponential function (StrEF) is proposed as an alternative model to fit the fluorescence decay of complex samples, in particular, biological tissue, ...
A bottleneck occurs in the funnel if F(n) has a maximum at n†, in which case τ f will be approximated by τ(n†): Apart from the dynamical factor D, this result resembles ordinary transition state theory. Due to the diffusive nature of the configurational change, however, ...
function. Under the condition of d d 0 , the dynamic re- sponse becomes dispersive in nature and hence is given by a stretched exponential function. The condition of d d 0 can be also satisfied, when we use an excitation light of shorter ...
our analysis aims to explore the dynamic nature of DE, particularly the intriguing possibility of encountering negative energy density values in the Universe’s late stages, thereby challenging conventional extensions of the standardCDM model [42,43,44,45,46,47,48,49,50,51,52]. In particular, ...
For example, an interesting dilemma for a debugging tool for parallel applications is the nature of breakpoint semantics as they relate to multiple execution contexts. Specifically, the question is whether to stop all execution contexts or just the one that encounters a breakpoint. The default beha...
3, while they are calculated in Fig. 4a, where the required window size Tw at the 95% confidence level is plotted as a function of λ for the variance (red curve) and autocorrelation (yellow curve). These are plotted together with the mean waiting time for n-tipping, tnoise, (blue ...
In the age of wisdom, computing power is productivity. What is productivity is the ability of human beings to transform nature and the ability to create value. In this table, we have an interesting discovery. Ten years ago, most of the companies with the highest market capitalization in the...
