similar to the sum and difference rules. But, the product rule does not work that way. For example, the derivative of f (x)=x2is f’ (x) = 2x and is not $\frac{d}{dx} (x) ∙ \frac{d}{dx} (x)$ = 1 ∙ 1 = 1. ...

We assume that the family is sufficient regular such that all analytical operations (such as differentiation under the integral sign) can be performed as needed. While a dualistic structure ( M , g , ∇ , ∇ * ) can be defined abstractly, in practice, it is often constructed by a ...
Food allergy (FA) is a condition with a growing incidence and is a constant concern for the medical world and healthcare providers. With potential symptoms including anaphylaxis, in the event of an allergic reaction the patient’s life may well be endang

where ϕ(t) is the instantaneous phase of the signal, and the prime (′) indicates differentiation. This formulation is justified below by considering first a constant-frequency signal, then a variable-frequency signal. Consider the amplitude-modulated signal (1.3.2)x(t)=a(t)cos(2πfct+...
For a dielectric elastomer actuator, the electric field induced stress can be found simply by calculating the compressive and extending forces per area through differentiation of the electrostatic energy density, u, stored in the elastomer with respect to either thickness or length. The electric field...
The ‘dot’ represents differentiation with respect to time (t). The unknown parameter vector Θ = [ Θ1Θ1 , Θ2Θ2 , Θ3Θ3 ]T has the true value Θtrue = [4, 0.4, 0.6]. Θ3Θ3 being a weak parameter, it does not affect the system dynamics much and hence its estimation ...
When the luminosity of a strongly lensed background source varies over time, such as an active galactic nucleus (AGN), the variability pattern manifests in each of the multiple images and is delayed in time due to the different light paths of the different images (see Fig. 1). The arrival...
Microbial evolution experiments can be used to study the tempo and dynamics of evolutionary change in asexual populations, founded from single clones and growing into large populations with multiple clonal lineages. High-throughput sequencing can be used to catalog de novo mutations as potential targets...
