Spectral reconstruction from RGB image to hyperspectral image: Take the detection of glutamic acid index in beef as an example.

The use of spectral reconstruction (SR) to recovery RGB images to full-scene hyperspectral image (HSI) is an important measure to achieve real-time and low-cost HSI applications. Taking the detection of glutamic acid index for 360 beef samples as an example, the feasibility of using 11 state-of-the-art reconstruction algorithms to achieve RGB to HSI in complex food systems was investigated. The multivariate correlation analysis was used to prove that RGB is a projection of three-channel comprehensive coverage wide-band information. The comprehensive quality attributes (PSNR-Params-FLOPS) was proposed to determine the optimal reconstruction model (MST++, MST, MIRNet, and MPRNet). Moreover, SSIM values and t-SNE were introduced to evaluate the consistency of the reconstruction results. Finally, Lightweight Transformer was used to establish the detection models of Raw-HSI, RGB and SR-HSI for the prediction of glutamic acid index for beef. The results showed that the MST++ model exhibited the best performance in SR, with RMSE, PSNR, and SSIM values of 0.015, 36.70, and 0.9253, respectively. Meanwhile, the prediction effect of MST++ (R2P = 0.8422 and RPD = 2.46) reconstructed was close to the Raw-HSI (R2P = 0.8526 and RPD = 2.69). The results provide practical application scenarios and detailed analysis ideas for RGB-to-HSI.

Psychological interventions for social anxiety disorder in children and adolescents: A systematic review and network meta-analysis.

BACKGROUND: Social anxiety disorder (SAD) is a high-prevalence mental disorder among children and adolescents. The aim of this study is to compare and rank the effectiveness of several psychotherapies for SAD among children and adolescents. METHODS: Only randomized controlled trials (RCTs) were utilized by searching PubMed, Embase, Cochrane Library, and Web of Science. We used network meta-analysis in the Bayesian framework to analyze the data. This study is registered with PROSPERO, number CRD42023476829. RESULTS: In total, 30 RCTs with 1547 individuals were included, and nine psychotherapies with three control conditions were compared and ranked in this study. The findings revealed that internet-delivered cognitive behavioural therapy (surface under the cumulative ranking curve [SUCRA: 71.2 %]), group cognitive behavioural therapy (SUCRA: 68.4 %), and individual cognitive behavioural therapy (SUCRA: 66.0 %) significantly reduced social anxiety symptoms; internet-delivered cognitive behavioural therapy also significantly decreased depression symptoms in these patients (SUCRA: 92.2 %). In addition, group cognitive behavioural therapy can enhance functioning in these patients (SUCRA: 89.6 %). CONCLUSION: These results suggest that internet-delivered cognitive behavioural therapy is the optimal type of psychotherapy for reducing social anxiety and depression symptoms in children and adolescents with SAD, internet-delivered parent-child interaction therapy and cognitive bias modification of interpretation have relatively poor treatment effects on social anxiety symptoms in children than other psychological interventions, and group cognitive behavioural therapy has better benefits in enhancing the functioning among children and adolescents with SAD. Further studies are needed to ascertain these results due to the limited number of included studies.

A new comprehensive quantitative index for the assessment of essential amino acid quality in beef using Vis-NIR hyperspectral imaging combined with LSTM.

The quality of beef is usually predicted by measuring a single index rather than a comprehensive index. To precisely determine the essential amino acid (EAA) contents in 360 beef samples, the feasibility of optimized spectral detection techniques based on the comprehensive EAA index (CEI) and comprehensive weight index (CWI) constructed by factor analysis was explored. Two-dimensional correlation spectroscopy (2D-COS) was used to analyse the mechanisms of spectral peak shifts in complex disturbance systems with CEI and CWI contents, and 15 sensitive feature variables were extracted to establish a quantitative analysis model of a long short-term memory network (LSTM). The results indicated that 2D-COS had good predictive performance in both CEI-LSTM (R2P of 0.9095 and RPD of 2.76) and CWI-LSTM (R2P of 0.8449 and RPD of 2.45), which reduced data information by 88%. This indicates that utilizing 2D-COS can eliminate collinearity and redundant information among variables while achieving data dimensionality reduction and simplification of calibration models. Furthermore, a spatial distribution map of the comprehensive EAA content was generated by combining the optimal prediction model. This study demonstrated that the comprehensive index method furnishes a new approach to rapidly evaluate EAA content.

Effect of Emotion on Prospective Memory in Those of Different Age Groups.

The effect of emotion on prospective memory on those of different age groups and its neural mechanism in Chinese adults are still unclear. The present study investigated the effect of emotion on prospective memory during the encoding and retrieval phases in younger and older adults by using event-related potentials (ERPs). In the behavioral results, a shorter response time was found for positive prospective memory cues only in older group. In the ERP results, during the encoding phase, an increased late positive potential (LPP) was found for negative prospective memory cues in younger adults, while the amplitude of the LPP was marginally greater for positive prospective memory cues than for negative prospective memory cues in older adults. Correspondingly, younger adults showed an increased parietal positivity for negative prospective memory cues, while an elevated parietal positivity for positive prospective memory cues was found in older adults during the retrieval phase. This finding reflects the increased attentional processing of encoding and the more cognitive resources recruited to carry out a set of processes that are associated with the realization of delayed intentions when the prospective memory cues are emotional. The results reveal the effect of emotion on prospective memory during the encoding and retrieval phases in Chinese adults, modulated by aging, as shown by a positivity effect on older adults and a negativity bias in younger adults.
