These results show clearly the power of multivariate analysis of fingerprint spectra to provide information about the biochemical changes occurring in the cuticle and cell wall during tomato fruit development However further work is needed to decipher the exact role of these compounds in the context of their IR absorptive properties Importantly the developmental time frame between 4 and 36

Frontiers

In this study we employed PLSR but many other multivariate statistical modeling techniques such as random forest (Baranowski et al 2015) support vector machines (Behmann et al 2014) and artificial neural networks (Singh et al 2016) can also be used This can be regarded as an advantage of hyperspectral imaging because these more sophisticated (and non-linear) modeling techniques

Machine learning in biopharmaceutical manufacturing

Modelling techniques and applications were assessed individually for both "bioprocess" "biopharmaceutics" and "monoclonal antibody" search terms Given the current availability of faster and more practical modelling packages several modelling approaches have been recently applied to biopharmaceutical process / product modelling in the above mentioned areas (Figure 2)

Prostate Cancer: Adjuvant Salvage Radiotherapy

Biochemical recurrence after surgery is defined as a detectable PSA level most of the published literature reports findings from the use of older RT techniques (e g external beam radiation therapy [EBRT] protocols) making it unclear whether newer techniques might result in fewer apparent differences between ART and SRT outcomes Given these issues the Panel concluded that it is not

Similar to other imaging techniques detection efficacy decreases with lesion size in PSMA-ligand PET Additionally detection is directly linked to the magnitude of PSMA overexpression in a metastasis In a meticulous analysis in recurrent-PC patients undergoing salvage lymph node dissection (sLND) PSMA-ligand PET detection rates for metastases were more than 50% and 90% when the short-axis

Biochemical Detection Applications Enabled by State

However so far only a limited number of research groups were able to measure biochemical reaction in water at room temperature [1] The standard Terahertz free-space measurement techniques have insufficient sensitivity to measure small relative dielectric permittivity changes at high water absorption level The state-of-the-art Terahertz sensor technology developed at ETRO-IR (VUB) can resolve

Stress and defense responses in plant secondary

In the growth condition(s) of plants numerous secondary metabolites (SMs) are produced by them to serve variety of cellular functions essential for physiological processes and recent increasing evidences have implicated stress and defense response signaling in their production The type and concentration(s) of secondary molecule(s) produced by a plant are determined by the species genotype

Multivariate PAT solutions for biopharmaceutical

Quality by design (QbD) and process analytical technology (PAT) are guiding principles stimulating the biopharmaceutical industry to improve understanding and control of their manufacturing processes and to ultimately build product quality into the process (Box 1) [1–8] To date classical chemical pharmaceutical production has achieved significant advances regarding QbD and PAT [9]

Multivariate Genome

The multivariate mixed model approach yielded 148 genome-wide significant single-nucleotide polymorphisms (SNPs) at a 10% false-discovery rate compared to 129 and 73 significant SNPs in the PC and univariate analyses respectively Thus explicit modeling of the correlation structure between fatty acids in a multivariate framework enabled identification of loci associated with variation in

The anthocyanin content in leaves can reveal valuable information about a plant's physiological status and its responses to stress Therefore it is of great value to accurately and efficiently determine anthocyanin content in leaves The selection of calibration method is a major factor which can influence the accuracy of measurement with visible and near infrared (NIR) spectroscopy

Tea cultivar classification and biochemical parameter

It is generally feasible to classify different species of vegetation based on remotely sensed images but identification of different sub-species or even cultivars is uncommon Tea trees (Camellia sinensis L ) have been proven to show great differences in taste and quality between cultivars We hypothesize that hyperspectral remote sensing would make it possibly to classify cultivars of plants

Deriving the conditional distributions of a multivariate

But there's also a theorem that says all conditional distributions of a multivariate normal distribution are normal Therefore all that's left is to calculate the mean vector and covariance matrix I remember we derived this in a time series class in college by cleverly defining a third variable and using its properties to derive the result more simply than the brute force solution in the
