In this study, we propose a new framework to perform visual simultaneous localization and mapping (SLAM) with RGB images artificially generated from thermal images in low light environments where an optical camera cannot be applied. We applied contrastive unpaired translation (CUT) and enhanced generative adversarial network for super-resolution (ESRGAN), which are image translation methods to generate a clear realistic RGB image from a thermal image. Oriented FAST and rotated BRIEF (ORB)-SLAM was performed using the super-resolution fake RGB image to generate a 3D point cloud. Experimental results showed that our thermography-based visual SLAM could generate a 3D temperature distribution map in the low light environment. © 2023 SPIE. All rights reserved.

Significant gender disparities and a general lack of support systems compound the state of mental health in developing countries. Women, in particular, face unique challenges due to societal norms and expectations that often restrict their access to mental health services. Additionally, the cultural stigma associated with mental health issues affects both men and women but can be particularly debilitating for women who may be less likely to seek help or disclose their struggles. This study explores the application of Jais-13B, a pre-existing bilingual Large Language Model (LLM) proficient in English and Arabic, tailored to address mental health inquiries. We employed a rich dataset encompassing both languages, essential for fine-tuning and enhancing Jais-13B's responsiveness and empathetic engagement in mental health contexts. The optimization focused on improving the model's ability to deliver accurate and contextually aware responses, which is crucial for effective mental health support. Performance evaluation using the cross-entropy loss function demonstrated that Jais-13B achieved an accuracy of 70.58%, indicating its capability to produce relevant and precise answers to mental health questions. These results showcase Jais-13B's potential to enhance digital mental health interventions significantly, providing accessible care solutions across diverse linguistic landscapes. This study reaffirms the effectiveness of bilingual LLMs in mental health applications and provides insights into their practical implementation, setting a foundational benchmark for future research in multilingual therapeutic chatbots. © 2025 IEEE.

Self-supervised learning for CT image denoising is a promising technique because it does not require clean target data that are usually unavailable in the clinic. Noise2void (N2V) is one of the famous methods to denoise the image without paired target data and it has been used to denoise optical images and also medical images such as MRI, and CT. However, the performance of the N2V is still limited due to the restricted receptive field of the network and it decreases the prediction performance for CT images that have complex image context and non-uniform Poisson random noise. Thus, we proposed enhanced N2V that utilizes penalty-driven network optimization to further denoise the images while preserving the important details. We used the total variation term to further denoise the image and also the laplacian pyramids term to preserve the important edges of the image. The degree of the influence of each penalty term is controlled by the hyperparameter value and they are optimized to achieve the best image quality in terms of noise level and structure sharpness. For the experiment, the real dental CBCT projection data were used to train the network in the projection domain. After the network training, the test results were reconstructed and compared at each different dose level. Meanwhile, PSNR, SNR, and a line profile were also evaluated to quantitatively compare the original FDK images, and proposed method. In conclusion, the proposed method achieved further denoises the image than N2V even preserving the details. By penalty-driven optimization, the network was able to learn the spectral features of the image while still the receptive field is limited to avoid identity mapping. We hope that our method would increase the practical utility of network-based CT images denoising that usually the target data are unavailable. © COPYRIGHT SPIE.

The nitride perovskite family has attracted widespread attention since the experimental synthesis of polar nitride perovskite LaWN3. In this work, we investigated the ferroelectric, dielectric, and piezoelectric properties of two nitride perovskites CeBN3 (B5+=Nb, Ta) using the first-principles calculation. Our results show that the polarization values of CeNbN3 (CNN) and CeTaN3 (CTN) approach those of typical perovskites LiNbO3 and BaTiO3, respectively. Interestingly, the A-site cation contributes significantly to the polarization of CNN and CTN, despite the lack of lone pair electrons in Ce4+. In addition, CTN and CNN exhibit unusually large static dielectric constants (>220) along the x direction, much larger than the y and z directions. This strong anisotropy primarily stems from the dominant infrared-active mode having a lower frequency or larger mode-effective charges along the x direction relative to the other two directions. Finally, we found both CTN and CNN have a comparatively large shear piezoelectric coefficient d24 over 70 pC/cm2. Our research provides insights for understanding the origin of ferroelectricity in nitride perovskites and their potential piezoelectric applications.
