The social foundations for re-solving herbicide resistance in Canterbury, New Zealand.

Synthetic herbicides have revolutionised agricultural weed control. Herbicide resistance (HR) is a natural process through which weeds evolve to be no longer susceptible to a herbicide. Repeated use of similar herbicides can lead to the proliferation of resistant weed populations, with detrimental on-farm effects.

Uncertainty in and around biophysical modelling: insights from interdisciplinary research on agricultural digitalization.

Agricultural digitalization is providing growing amounts of real-time digital data. Biophysical simulation models can help interpret these data. However, these models are subject to complex uncertainties, which has prompted calls for interdisciplinary research to better understand and communicate modelling uncertainties and their impact on decision-making.

Tensor representation techniques for full configuration interaction: A Fock space approach using the canonical product format.

In this proof-of-principle study, we apply tensor decomposition techniques to the Full Configuration Interaction (FCI) wavefunction in order to approximate the wavefunction parameters efficiently and to reduce the overall computational effort. For this purpose, the wavefunction ansatz is formulated in an occupation number vector representation that ensures antisymmetry. If the canonical product format tensor decomposition is then applied, the Hamiltonian and the wavefunction can be cast into a multilinear product form.

Tensor decomposition in post-Hartree-Fock methods. I. Two-electron integrals and MP2.

A new approximation for post-Hartree-Fock (HF) methods is presented applying tensor decomposition techniques in the canonical product tensor format. In this ansatz, multidimensional tensors like integrals or wavefunction parameters are processed as an expansion in one-dimensional representing vectors. This approach has the potential to decrease the computational effort and the storage requirements of conventional algorithms drastically while allowing for rigorous truncation and error estimation.

A new approach to biofunctionalisation and micropatterning of multi-well plates.

Biomolecule attachment and lateral micropatterning of biomolecular layers are essential techniques to provide in advanced biochemical and cell culture assays. For that purpose, we introduced a versatile, simple and robust method to functionalise standard polystyrene well plates. Free amino groups were generated on the polystyrene surface by low pressure ammonia plasma treatment.
