Predicting the Lime Demand of Arable Soils from pH Value, Soil Texture and Soil Organic Matter Content

open access: yesAgronomy, 2021
For more than 40 years, farmers in Germany have used the fertilization recommendation schema provided by the Association of German Agricultural Investigation and Research Institutions (VDLUFA) to quantify the required lime (CaO) demand of arable mineral ...

Continuous-Like Linear Operators on Bilinear Spaces

open access: yesJournal of Mathematical and Fundamental Sciences, 2020
This paper introduces continuous-like linear operators on bilinear spaces as a generalization of continuous linear operators on Hilbert spaces. It is well known that the existence of the adjoint of a linear operator on a Hilbert space is equivalent to ...

Dynamic Time Warping of Pulse Wave Curves

open access: yesCurrent Directions in Biomedical Engineering, 2018
Being able to non-obtrusively and continuously monitor arterial blood pressure is of great interest, particularly in the context of wearable sensors. A common limitation is the need for dedicated hardware, which is either obtrusive or expensive.

Let Continuous Outcome Variables Remain Continuous [PDF]

open access: yesComputational and Mathematical Methods in Medicine, 2012
The complementary log-log is an alternative to logistic model. In many areas of research, the outcome data are continuous. We aim to provide a procedure that allows the researcher to estimate the coefficients of the complementary log-log model without dichotomizing and without loss of information.

Magnitude processing in non-symbolic stimuli

open access: yesFrontiers in Psychology, 2013
Dot arrays are often used to study basic numerical skills across cultures, species and development. Researchers investigate the ability of subjects to discriminate between dot arrays, as a function of the ratio or distance between their numerosities ...

Continuous first-passage percolation and continuous greedy paths model: linear growth [PDF]

open access: yes, 2007
We study a random growth model on $\R^d$ introduced by Deijfen. This is a continuous first-passage percolation model. The growth occurs by means of spherical outbursts with random radii in the infected region.
