Antireflection Surfaces for Biological Analysis Using Laser Desorption Ionization Mass Spectrometry
Research, 2018 Laser desorption ionization mass spectrometry (LDI-MS) is a primary tool for biological analysis. Its success relies on the use of chemical matrices that facilitate soft desorption and ionization of the biomolecules, which, however, also limits its ...

SOURCE IDENTIFICATION OF ENVIRONMENTAL POLLUTANTS USING CHEMICAL ANALYSIS AND POSITIVE MATRIX FACTORIZATION [PDF]
, 2012 Multivariate modeling techniques are successfully used in different areas of environmental research because of their ability to process large data sets. The main objective of their application lies in the determination of data structures and hidden information which account for the data set variability. This thesis work seeks to explore the application

Detecting Anomaly in Chemical Sensors via L1-Kernels based Principal Component Analysis [PDF]
arXiv, 2022 We propose a kernel-PCA based method to detect anomaly in chemical sensors. We use temporal signals produced by chemical sensors to form vectors to perform the Principal Component Analysis (PCA). We estimate the kernel-covariance matrix of the sensor data and compute the eigenvector corresponding to the largest eigenvalue of the covariance matrix.

Mass Spectrometry-Based Chemical and Enzymatic Methods for Global Analysis of Protein Glycosylation.
Accounts of Chemical Research, 2018 Glycosylation is one of the most common protein modifications, and it is essential for mammalian cell survival. It often determines protein folding and trafficking, and regulates nearly every extracellular activity, including cell-cell communication and ...
