Note on Mr. Reynolds's Dark-slides

A Note on Agegraphic Dark Energy

Recently a new model of dynamical dark energy, or time-varying Λ, was proposed by Cai [arXiv:0707.4049] by relating the energy density of quantum fluctuations in a Minkowski spacetime, namely ρq ≡ 3n2m2P /t, where n ∼ O(1) and t is the cosmic time, to the present day dark energy density. In this note, we show that the model can be adjusted to the present values of dark energy density parameter ...

Operational Note Temporal and Storage Effects on Ultra-low Volume Droplets of Insecticides Collected on Teflonh-coated Slides

Use of microscope slides is the most commonly used method to field-assess the droplet spectrum of ultra-low volume (ULV) sprays. Due to absence of analysis facilities during military deployments, slides must be stored and shipped, and the impact of delays in processing and storage conditions on droplets is unknown. This study was designed to evaluate the effect of storage temperatures and durat...

Consider the initial value problem u = f (u, t), u(t 0) = u 0 An mth order system of s equations can be reduced to a system of ms first order equations, by introducing new variables v 1 = u , v 2 = u ,. .. , v m−1 = u (m−1). The explicit time-dependency can be removed by introducing a new variable w = t with the trivial equation w = 1, to obtain a new autonomous system of equations A linear sys...
