Weed Control Using Conventional Tillage, Reduced Tillage, No-Tillage, and Cover Crops in Organic Soybean

Soybean field experiments were performed to investigate the weed-suppressing effects of different tillage systems and cover crop mulches at two locations in southwest Germany during 2014 and 2015. The influence of three different tillage systems on weed control efficacy, soybean plant density, and crop yield was determined. In the no-till system (NT), two different cover crops, (rye and barley)...

Universal failure model for multi-unit systems with shared functionality

A Universal Failure Model (UFM) is proposed for complex systems that rely on large number of entities for performing a common function. Economy of scale or other considerations may dictate the need to pool resources for the common purpose, but the resulting strong coupling precludes the grouping of those components into modules. Existing system-level failure models rely on modularity for reduci...

A universal model of single-unit sensory receptor action.

We present a model governing the operation of all "isolated" sensory receptors with their primary afferent neurons. The input to the system is the intensity of a sensory signal, be it chemical, optical etc., and the output is the rate of neural impulse transmission in the afferent neuron. The model is based on the premise that information is conserved when transmitted by an efficient sensory ch...
