The method involves recovering Bisphenol A (BPA) monomer from a thermoset BPA-epoxy resin through alcoholysis using a C1-C3 alcohol and a hydroxide as a reaction promoter. This process is conducted under an inert atmosphere at a pressure of at least 10 bar and a temperature between 200-225°C for a minimum of 5 hours. The method allows for high yields of BPA monomer with reduced reaction times and less base usage compared to existing methods. The process includes loading 2-10 wt.% of the resin in the alcohol and can involve further steps such as crystallization and recrystallization for purification.

The method involves identifying tumor-specific antigens in non-small cell lung cancer (NSCLC) by obtaining tumor and non-tumor tissue samples from patients and performing RNA sequencing to identify genomic variants. Patient-specific databases are generated, and mass spectrometry-based immunopeptidomics is used to detect MHC class I-bound and MHC class II-bound variant peptides in tumor tissue samples. A subset of these peptides, exclusive to tumor samples, is identified and confirmed for strong association with patient-specific MHC molecules using MHC allotype predictions. This subset is recognized as tumor-specific antigens in NSCLC.

The present disclosure relates to a system and computer-implemented method for thermal characterization of buildings to assist in thermal assessment and/or control. A novel approach combining black-box and grey-box modeling techniques is integrated. Initially, a black-box fit is employed to generate model parameters based on training data specific to a building. These parameters are then used to establish initial parameters for a grey-box model through a parameter mapping process, which translates black-box model parameters into an equivalent set of grey-box model parameters while employing predefined equations and constraints to align the grey-box model with outcomes from the black-box model. The grey-box model parameters are further refined iteratively by fitting them against observed data using optimization techniques. This refinement aims to minimize discrepancies between model predictions and actual observations, with constraints imposed on the black-box model parameters to restrict the solution space during modeling.
