The paper “Model-based pre-processing in Raman spectroscopy of biological samples”, authored by Kristian Hovde Liland, Achim Kohler and Nils Kristian Afseth has been published in Journal of Raman Spectroscopy. Abstract Model-based pre-processing has become wide spread in spectroscopy and is the standard procedure in Fourier-transform infrared spectroscopy. It has also been shown to give valuable contributions…
The paper “Variable selection in multi-block regression” authored by Alessandra Biancolillo, Kristian Hovde Liland, Ingrid Måge, Tormod Næs and Rasmus Bro has been published in Chemometrics and Intelligent Laboratory Systems. Abstract The focus of the present paper is to propose and discuss different procedures for performing variable selection in a multi-block regression context. In particular, the focus is on…
The paper “On-line and non-destructive measurement of core temperature in heat treated fish cakes by NIR hyperspectral imaging” authored by Jens Petter Wold has been published in Innovative Food Science and Emerging Technologies. Abstract During industrial heat treatment of food products the core temperature is a critical control parameter with respect to food quality and in particular food…
The paper “The relationship between fatty acid profiles in milk identified by Fourier transform infrared spectroscopy and onset of luteal activity in Norwegian dairy cattle” co-authored by Ingrid Måge and Nils Kristian Afseth has been published in Journal of Dairy Science. Abstract To investigate the feasibility of milk fatty acids as predictors of onset of…
The paper “Single Cell Confocal Raman Spectroscopy of Human Osteoarthritic Chondrocytes: A Preliminary Study” co-authored by Nils Kristian Afseth has been published in International Journal of Molecular Sciences. Abstract A great deal of effort has been focused on exploring the underlying molecular mechanism of osteoarthritis (OA) especially at the cellular level. We report a confocal…
The paper “Noninvasive Analysis of Thin Turbid Layers Using Microscale Spatially Offset Raman Spectroscopy” co-authored by Nils Kristian Afseth has been published in Analytical Chemistry. Abstract Here, we demonstrate, for the first time, the extension of applicability of recently developed microscale spatially offset Raman spectroscopy (SORS), micro-SORS, from the area of cultural heritage to a…
The paper “Optical investigation of osteoarthritic human cartilage (ICRS grade) by confocal Raman spectroscopy: a pilot study” co-authored by Nils Kristian Afseth has been published in Analytical and Bioanalytical Chemistry. Abstract Biomolecular changes in the cartilage matrix during the early stage of osteoarthritis may be detected by Raman spectroscopy. The objective of this investigation was…
Volha Shapaval has authored a paper on Fourier transform infrared spectroscopy for the prediction of fatty acid profiles in Mucor fungi together with Nils Kristian Afseth, Gjermund Vogt and Achim Kohler. Abstract Fungal production of polyunsaturated fatty acids (PUFAs) is a highly potential approach in biotechnology. Currently the main focus is directed towards screening of hundreds strains…
