In this equation c is the concentration of EDB in g/m3and t is the lapsed time in minutes; k is the natural log of the nominal dosage and b is a parameter which depends on the contents of the fumigation chamber. The b value is obtained from the linear relationship In [(In c)/k]...
In the current manuscript, we work on the central values of urinary concentrations of phthalates and phthalate replacements. As central values, for publications where medians and geometric means (GM) were reported, both values were compiled, due to the generally lognormal distribution of urinary pht...
1), (2) synaptic release is much more than scalar weights, involving a nonlinear transmission of neurotransmitters, the probability of activation of receptors and the concentration of available neurotransmitters, among other nonlinearities (see S(t) in Fig. 1) and (3) the propagation of ...
However, the experimentalist usually has a priori knowledge about which shapes of concentration profiles or spectra are realistic. This amounts to common statements regarding continuity, nonnegativity, unimodality, etc. A large amount of research is based upon such physical constraints in the self...

It can also happen when the wafer is coated with a material (usually a dielectric) that has a high positive or negative charge, or a material with a work function different from that of silicon. If the asymmetry in carrier concentration is very strong in equilibrium, it usually remains so ...
The circadian clock is an endogenous time-tracking system that anticipates daily environmental changes. Misalignment of the clock can cause obesity, which is accompanied by reduced levels of the clock-controlled, rhythmic metabolite NAD+. Increasing NAD+
In the following, we discuss how to realize such an inherent time crystal in experiments. We used erbium-doped yttrium orthosilicate (Er:Y2SiO5) with a concentration of 1000 ppm, corresponding to an average distance between erbium ions of approximately 4 nm, such that the average magnetic...
