GUEST COMMENTARY Bacterial Growth: Constant Obsession with dN/dt
One of life’s inevitable disappointments—one felt often by scientists and artists, but not only by them—comes from expecting others to share the particularities of one’s own sense of awe and wonder. This truth came home to me recently when I picked up Michael Guillen’s fine book Five Equations That Changed the World (4) and discovered that my equation—the one that shaped my scientific career—wa...
متن کاملCommentary: why are there difficulties in controlling genetic variability?
More than 20 years ago, K. Gärtner published a paper in the journal Laboratory Animals. According to the author: ‘Reduction of genetic variability by using inbred strains and reduction of environmental variability by highly standardized husbandry in laboratory animals did not remarkably reduce the range of random variability in quantitative biological traits.’ As far as I can see, this statemen...
متن کاملCOMMENTARY: The productivity of variability: an agroecological hypothesis
Most agronomic research seeks to limit the variability of productivity, offering universal ‘recipe knowledge’ that attempts to overwhelm contextual differences. Based on participatory research with a group of eight graziers in Wisconsin, we present the counter hypothesis that the productivity of variability is a key principle of agroecology. Contextual variability across space and time presents...
متن کاملCommentary: Heart rate variability and self-control–A meta-analysis
In relation to the paper “Heart rate variability and self-control: a meta-analysis,” we have recommendations that may be of importance when considering future research on HRV and self-control. The following commentary will cover three main points which consist of: (1) a systematic use of the terms “vagal/parasympathetic” instead of heart rate variability (HRV), as vagal tone is the real physiol...
متن کاملStereothresholds with simulated vergence variability and constant error
Stereothresholds are elevated by vergence constant error (fixation disparity), vergence noise, or both. This study investigated the separate and combined effects of simulated vergence constant error and variability on stereothresholds in four normal observers. Targets were 30 arc min bright vertical lines presented separately to the two eyes for 150 ms in darkness. Vergence constant error, simu...
