Summary: The study aims to explore the mechanism of chlorophyll changes during Tencha processing and evaluate the feasibility of predicting its content using a portable near-infrared (NIR) spectrometer. Various preprocessing techniques were used to preprocess the Tencha samples' spectral data, and IVSO, BOSS, and CARS were used to optimize and build PLS models. The CARS-PLS models achieved the best predictive accuracy, with correlation coefficients of prediction (Rp) = 0.9204 for chlorophyll a, Rp = 0.9282 for chlorophyll b, and Rp = 0.9385 for total chlorophyll. These findings suggest that NIR spectroscopy could be used as a surrogate for immediate quantification and monitoring of chlorophyll during Tencha processing.

Summary: This study aims to develop a comprehensive multimodal anesthesia depth monitor by understanding the neural and hemodynamic responses during general anesthesia using fNIRS and EEG. The research found a significant decrease in the complexity and power of fNIRS signals during the maintenance phase of anesthesia and variations in responses to anesthesia between adults and children. Multimodal approach could provide a reliable measure of anesthesia depth, taking into account specific differences between age groups.

Summary: Near-infrared spectroscopy (NIRS) technology is a noninvasive tool that detects changes in hemoglobin concentration in human tissues through optical signals, allowing for the determination of muscle activation states. A multichannel NIRS system is essential for motion recognition, and the wireless communication and equipped upper computer system improve real-time monitoring and accuracy. The analysis of NIRS signals using common mode and difference mode shows superior performance.

Summary: This study examined the effects of ketamine and midazolam on grey seals' physiological responses during prolonged anaesthesia trials using NIRS data. The results showed that both anesthetics led to apnoea in the seals, with an increase in Delta HHb while SpO(2) remained stable, indicating possible venous congestion. NIRS was found to be a valuable real-time monitoring tool for safe anaesthetic procedures in pinnipeds.

Summary: Near-infrared spectroscopy (NIR) was used to monitor the curing degree of a bio-based epoxy resin in resin transfer molding (RTM) process, with the development of calibration models using a NIR micro-spectrometer and chemometrical algorithms. Different pre-treatments of spectroscopic data were tested, with direct current (DC) and differential scanning calorimetry (DSC) as reference methods for the degree of curing. Results show the potential of cost-efficient and compact NIR micro-spectrometers for inline monitoring purposes.

Summary: Principal component analysis (PCA), subtractive spectroscopy, and two-dimensional correlation spectroscopy (2D-COS) were used to explain changes of characteristic groups in the extraction process of Swertia mussotii Franch. (SMF). Four main characteristic peaks at 1884 nm, 1944 nm, 2246 nm, and 2308 nm were identified to describe the changes of molecular structure information of total active components in the SMF extraction process. In addition, multi critical quality attributes (CQAs) models were established by near-infrared spectroscopy (NIRS) combined with the total quantum statistical moment (TQSM), showing high accuracy and efficiency. These results demonstrated the feasibility of understanding the SMF extraction process and achieving visual digital characterization and quality stability.

Summary: A rapid and simple method based on vibrational spectroscopic techniques was developed to understand biochemical changes during the ripening process of Turkish white cheese and generate predictive algorithms. The models showed good correlation between predicted values by vibrational spectroscopy and reference values, providing real-time tools for addressing deviations in cheese manufacturing. Portable vibrational spectroscopy units can be used for rapid in-situ monitoring of cheese quality during aging.

Summary: This study proposed a method of element identification and pollution degree monitoring of Cu and Pb pollution in corn using variational mode decomposition (VMD) and bispectrum estimation. The results showed that the u(3) component of VMD was sensitive to corn heavy metal monitoring. The bispectrum graphs of healthy corn leaves, Cu polluted, and Pb polluted were significantly different, which could quickly distinguish whether corn was polluted by heavy metals and the categories of pollution elements. The pollution prediction models constructed by the combination of normalized frequency (f(m)) and energy entropy (W-ee) effectively monitored the pollution of Cu and Pb in corn.

Summary: Pathological psychologies such as anxiety, depression, and body dysmorphic disorder (BDD) are common in female patients scheduled to undergo rhinoplasty. BDD is more likely to be associated with depression. Rhinoplasty has little psychological impact on patients, but female patients with BDD are more likely to be dissatisfied with the surgery.

Summary: This study analyzed complications following cosmetic surgeries managed by plastic surgery services at Heatherwood and Wexham Park hospitals in 2022, including procedures performed internationally. The majority of complications were related to breast cosmetic surgery and abdominoplasties, with the most common complications being wound dehiscence, post-operative infection, and seromas. Turkey was the most popular country selected for surgery, and there is a need to increase public awareness of the risks involved in seeking international options and how to choose suitable clinics.

Summary: The study aims to compare the oncologic, medical, and surgical outcomes of lumpectomy and oncoplastic breast reduction surgery (OBRS) on a national scale. A database was used to analyze patient data and match them based on various factors. The results showed that lumpectomy patients had higher rates of repeat lumpectomy or subsequent mastectomy, while OBRS patients had higher rates of surgical complications but fewer medical complications. Logistic regression analysis revealed that OBRS was associated with a decreased likelihood of repeat lumpectomy. Although OBRS was associated with increased wound complications, medical complications were found to occur less frequently.
