A review and discussion under the following headings: history; liquid (non-aggregate) hydroponic
systems; aggregate hydroponic systems; nutrient solutions; disease and insect control; …

Organisms are equipped with regulatory systems that display a variety of dynamical behavior
ranging from simple stable steady states, to switching and multistability, to oscillations. …

We propose a description of normalized distributions (measures) lying upon possibly fractal
sets; for example those arising in dynamical systems theory. We focus upon the scaling …

The long-period helical magnetic structures in MnSi and FeGe are shown to be
consequences of a ferromagnetic Dzyaloshinskii instability (1964). Renormalisation group …

Reduced models for hydrodynamic turbulence; 4. Turbulence and coupled map lattices; 5. …

Whereas the stress-inducible heat-shock protein 70 (Hsp70) has gained plenty of attention
as a putative target for tumor therapy, little is known about the role of other Hsp70 proteins in …

Molecular motors in cells typically produce highly directed motion; however, the aggregate,
incoherent effect of all active processes also creates randomly fluctuating forces, which drive …

Dissipative dynamical systems with two competing frequencies exhibit transitions to chaos.
We have investigated the transition through a study of discrete maps of the circle onto itself. …

Background The trans-membrane protease serine 2 (TMPRSS2) is essential for severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2) cell entry and infection. Efficacy and …
