Summary: Generative adversarial linear discriminant analysis (GALDA) is a useful tool for improving classification accuracy and reducing overfitting in spectrochemical analysis. It is inspired by the success of generative adversarial neural networks (GANs) in minimizing overfitting in artificial neural networks, but GALDA has its own distinct linear algebra framework. GALDA performs data augmentation by excluding regions in spectral space where genuine data does not exist. Compared to non-adversarial methods, GALDA shows significant improvements in dimension reduction and classification accuracy.

Summary: The study compared the performance of blood plasma, serum, and ascitic fluid in ovarian cancer detection using Raman microspectroscopy. Ascitic fluid showed the best class separation in both unsupervised and supervised discrimination approaches, with higher classification accuracies, sensitivities, and specificities compared to plasma or serum. The presence of collagen information in ascitic fluid was found to be responsible for distinguishing ovarian cancer samples, making it a potential diagnostic method for ovarian cancer.

Summary: This study investigates the modulation of birefringence on the angle-resolved polarized Raman spectroscopy (ARPRS) response and the intrinsic response using transparent birefringent crystal alpha-MoO3. The anomalous ARPRS responses in alpha-MoO3 can be well explained by the birefringence-induced Raman selection rules. The thickness-dependent study shows that birefringence modulates the ARPRS response to create an interference pattern.

Summary: In this study, a 1D hierarchical convolutional neural network (H-CNN) was proposed to accurately identify different stages of cervical cancer using Raman spectroscopy. The H-CNN outperformed traditional methods in terms of recognition accuracy, stability, and sensitivity, with a macro-accuracy of 94.91%. The hierarchical classification method proposed in this study can diagnose patients more accurately and lays the foundation for further research on Raman spectroscopy as a clinical diagnostic method for cervical cancer.

Summary: This study investigates the effect of different polarization states of excitation light on the unpolarized Raman spectra of unstructured samples. The results demonstrate that the intensity ratio of Raman peaks varies depending on the polarization state of the excitation light. Specifically, the intensity of peaks related to functional groups and C-H stretching modes increases when circular polarization is applied, which is beneficial for studying liquid mixtures with low concentrations.

Summary: Linear Discriminant Analysis (LDA) assumes samples from the same class are independently and identically distributed, which may lead to failure when there are multiple clusters within a class. This paper proposes a neighborhood linear discriminant analysis (nLDA) that defines scatter matrices based on a neighborhood of reverse nearest neighbors, eliminating the need for the i.i.d. assumption. Experimental results show that nLDA outperforms previous discriminators in terms of performance.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
