We present a novel mathematical model that seeks to capture the key design feature of generative adversarial networks (GANs). Our model consists of two interacting spin glasses, and we conduct an extensive theoretical analysis of the complexity of the model's critical points using techniques from Random Matrix Theory. The result is insights into the loss surfaces of large GANs that build upon prior insights for simpler networks, but also reveal new structure unique to this setting which explains the greater difficulty of training GANs.

This study introduces a deep learning-based automatic evaluation method for analyzing the microstructure of steel with scanning electron microscopy (SEM), aiming to address the limitations of manual marking and subjective assessments by researchers. By leveraging advanced computer vision algorithms, specifically a suitable model for long-term dendritic solidifications named Tang Rui Detect (TRD), the method achieves efficient and accurate detection and quantification of microstructure features. This approach not only enhances the training process but also simplifies loss function design, ultimately leading to a proper evaluation of surface modifications in steel materials.

Limbal stem cell deficiency (LSCD) causes vision loss and is often treated by simple corneal epithelial cell transplantation with poor long-term efficiency. Here, we present a biomimetic bilayer limbal implant using digital light processing 3D printing technology with gelatin methacrylate (GelMA) and poly (ethylene glycol) diacrylate (PEGDA) bioinks containing corneal epithelial cells (CECs) and corneal stromal stem cells (CSSCs), which can transplant CECs and improve the limbal niche simultaneously. The GelMA/PEGDA hydrogel possessed robust mechanical properties to support surgical transplantation and had good transparency, suitable swelling and degradation rate as a corneal implant.

Plastic pollution, especially microplastics (MPs), is a severe environmental threat. Due to the significant environmental issues posed by plastics, it is critical to use an effective and sustainable degradation technique. The study aimed to isolate and identify Indigenous bacterial strains from landfill leachate (LL) to evaluate its potential for degrading Polypropylene microplastics (PPMPs).

: The aim is to bring attention to the existence of a rare type of trauma of the hand, high-pressure injection injury, that appears to be minor with negligible signs and symptoms within the first hours after the accident, but in reality, produces significant tissue destruction with severe consequences. Recognizing this type of trauma by medical personnel, understanding the mechanisms involved, and knowing the etiological and prognostic factors can lead to early treatment initiation and avoid severe mutilating sequelae. : A retrospective study on 16 patients diagnosed with high-pressure injection injuries, including water, air, paint, paint mixed paint with thinner, petroleum jelly, and lime (washable paint containing calcium oxide).
