The Dutch Chemometrics Society is pleased to announce its new board. With this new team in place, we are looking ahead with renewed enthusiasm and a clear ambition: to bring new energy to the chemometrics community in the Netherlands.

Chemometrics continues to play an important role in connecting data, modelling, and real-world applications across science and industry. As a society, we want to strengthen that connection by creating more opportunities for exchange, discussion, and collaboration between researchers, students, and professionals working in this field. The new board is committed to supporting an active and visible community in which knowledge sharing, inspiration, and networking remain central.

The new DCS board consists of Rita Folcarelli, Agnieszka Smolinska, Ewa Szymańska, Ewoud van Velzen, Robert van Vorstenbosch, Andrea Junior Carnoli, and Tijmen Bos. Together, they represent a broad range of expertise across academia and industry, and they are motivated to further strengthen the position of chemometrics in the Netherlands.

In the coming period, the board will focus on stimulating interaction within the community and creating attractive activities for members and other interested professionals. A first step in this will be the first digital session with talks, which will take place in June. More information about the programme and speakers will follow soon, so we encourage everyone to keep posted.

We are excited about this new chapter for the Dutch Chemometrics Society and look forward to meeting many of you during upcoming activities and events.

We are excited to announce the new DCS PhD Spotlight sessions, a series of free online seminars where PhD students will present their work. The first Spotlight session will held on-line via Zoom on Friday April the 1^st from 12:30-13:30 CET. The presenters are Roel van der Ploeg (University of Amsterdam) and Pieter Dekker (Wageningen University and Research).

As a consequence of the Covid pandemic, most of the scientific conferences and events have followed a short online format with few keynote talks in the program. While this has still allowed professionals and renowned scientific speakers to share their research, PhD students had less opportunities to present their work and get valuable feedback from the scientific community during their first steps in academia.

As it will still take some time to get back to the pre-pandemic situation in international traveling and face to face events, The Dutch Chemometrics Society would like to provide PhD students a platform to share their research around Chemometrics and related disciplines.

For this reason we are excited to announce the new DCS PhD Spotlight sessions, a series of free online seminars where PhD students will present their work.

The first Spotlight session will held on-line Friday April the 1^st from 12:30-13:30 CET.

Program:

• Talk 1: Data integration of oral microbiome and metabolome data using PARAFAC, by Roel van der Ploeg (Swammerdam Institute for Life Sciences, University of Amsterdam)
  • Summary: Dental plaque is a biofilm and an important indicator of oral health. Its formation is caused by the establishment of a local bacterial community that connects to the tooth surface using physico-chemical interactions. If not removed by good brushing, dental plaque can accumulate and mature, thus leading to the development of gingivitis: inflammation of the gums. In some people, the development of gingivitis goes much faster and to a greater severity than in others. However, not much is known about the link between gingivitis severity and the oral microbiome and metabolome. A cohort of 41 individuals were subjected to a two-week gingivitis intervention, in which they were not allowed to brush their teeth. Microbiome samples were taken at multiple sites in the mouth, before, during, and after the intervention period. Metabolome samples were collected from saliva only during the intervention period. Hence we have obtained two multiway datasets with modes in the individual, measured variable, and time directions. In this study, we aim to connect the microbiome and metabolome by searching for common patterns using PARAFAC, a multiway decomposition method. PARAFAC decomposes a dataset into components with a loading vector for each mode. By comparing these components between the microbiome and metabolome data blocks, we can search for commonalities for example in the time profile loading. This way we aim to find connections between microbial species and metabolites that show a similar response to the gingivitis intervention over time.
• Talk 2: Human milk proteins and allergy of mother and child: exploring differences at the univariate and network level, by Pieter Dekker (Department of Agrotechnology and Food Sciences, Wageningen University and Research) 
  • Summary: The human milk proteome comprises a vast amount of proteins with immunomodulatory functions, but it is not clear how this relates to an allergy of the mother or allergy development in the breastfed infant. In this study, we aimed to explore the relation between the human milk proteome and allergy of both mother and infant. We analyzed proteins in a selection of 300 human milk samples from the Canadian CHILD Cohort Study. In the analysis of the data, univariate, multivariate, and network analyses were employed to explore relations between the different groups of allergy statuses.

The session will be streamed online via Zoom platform, will last around 1 hour, and is free of charge. You do not need to register for this event. The Zoom link f will be shared the same day of the event via e-mail to all those who are subscribed to the Dutch Chemometrics Society mailing list. You can subscribe to the DCS mailing list here.

The Dutch Chemometrics Society (DCS) is excited to announce the second DCS PhD Spotlight session, in which the presentations will be related to NIR data analysis.

The second session will be held on May 12th (Thursday) from 12:30-13:30.

Program:

• Talk 1: Predicting the performance of handheld near-infrared sensors from a master benchtop device, by Mark Schoot (Radboud University Nijmegen, NutriControl Analytical Solutions)

  • Many industries see a shifting focus towards performing on-site analysis using handheld spectroscopic devices. Myriad handheld solutions with very different specifications and pricing are available on the market. Although specifications are generally available for new devices, this does not directly quantify or predict how available devices will perform for targeted cases. We present a novel chemometric method to estimate the prediction performance of handheld NIR hardware and apply it to estimate the performance of two commercially available handheld NIR technologies in predicting protein content in pig feed from existing data of a benchtop device. Our method utilizes information on the error structure of the handheld devices for the estimation. It yielded performance estimates differing less than 1 g kg-1 from the experimentally determined handheld performances and similar model parameters. Our method was effective for linear and nonlinear calibration algorithms, also when estimating performance after averaging multiple scans. Overall, our method provides estimates of the performance of a handheld device for a specific task with minimal testing required and can thus be used as a device or application screening tool before committing to develop calibrations.

• Material Fingerprinting in the Mining industry – Clustering of VNIR–SWIR and geochemistry data, by Jeroen van Duijvenbode (Delft University of Technology)

  • Within the mining industry, a lot of spectral and geochemical data is collected from rock samples to indicate the properties of the different styles of mineralization in an orebody. The quantity of these data increases rapidly during the daily operations of a mine since every one-meter composite sample is tested. This presentation will focus on interpreting these large (combined >250,000 samples) multivariate datasets using compositional data analysis, principal component analysis and clustering in two parts. The first part will focus on VNIR-SWIR data and the second part combines this with the geochemical data. Commonly, VNIR-SWIR data are analyzed by extracting specific absorption features, however, this way, not all potential value is extracted from the spectral responses, as will be shown. In this study, we clustered spectral range values and, using this found a new spectral feature region related to epidote not recognized before. Furthermore, within a spatial contextual relationship, it was found that this epidote feature also relates to the rock hardness, which is important during the crushing and grinding of rocks to extract gold.

The session will be streamed online via Zoom platform, will last around 1 hour, and is free of charge. You do not need to register for this event. The Zoom link will be shared the same day of the event via e-mail to all those who are subscribed to the Dutch Chemometrics Society mailing list. You can subscribe to the DCS mailing list here.
