    Abstract: The present invention relates to a method of preparing N-acyl amino acids selected from N-acyl cysteine compounds, N-acyl serine compounds, N-acyl aspartic acid compounds and N-acyl glutamic acid compounds. The present invention also relates to the use of N-acyl cysteine, N-acyl serine, N-acyl aspartic acid and N-acyl glutamic acid surfactants, in removing per- and poly-fluoroalkyl substances (PFASs) from mixtures containing PFASs, such as soil and groundwater contaminated with PFASs and for use in cleaning compositions, detergent compositions and toothpaste compositions.

    Abstract: A method of using a trained classifier to detect a change in temperature or an environmental cause of a change in temperature. The classifier is trained to detect a change in temperature by extracting channel signal information (CSI) amplitudes for each of a plurality of wireless networking signals received at a wireless communication device, each signal associated with a change in temperature and for each signal, analysing subcarriers of the extracted CSI amplitudes and determining a relationship between amplitude and temperature. The training comprises selecting a subset of the plurality of subcarriers based on the determined relationship; and training the classifier using the CSI amplitudes of the selected subcarriers. The trained classifier is provided with a selected subset of carriers of CSI amplitudes extracted for each of a plurality of wireless networking signals received at a wireless communication device to determine if a change in temperature has occurred.

    Abstract: The present disclosure relates to a method of decoding Low-Density Parity-Check (LDPC) codes in received data. The method comprises determining check nodes, variable nodes, and variable-to-check (VTC) messages based on the LDPC codes. Three or more minimum magnitude values of the determined VTC messages are then determined to obtain a determined minimum VTC message set. A set of check node messages from the determined minimum VTC message set is also determined, wherein the determined set of check node messages and the determined minimum VTC message set are used to determine a set of check-to-variable (CTV) messages. The present disclosure also relates to a corresponding method for encoding.
