Summary: FPGA technology has shown high computational performance in various applications, particularly suitable for high real-time requirements such as medical image analysis and high-energy physics particle trajectory recognition. This paper demonstrates the hardware implementation of complex algorithms using FPGA, proving that this technique can be accelerated not only through software-based systems, but also through consumer hardware devices. Xilinx UltraScale+ FPGA, as a member of the frontier family devices on the market, features high clock frequencies and acceptable energy consumption.

Summary: This paper proposes a fast region homogenization method to obtain particle information and quickly calculate homogenization information from particle motion images, accelerating the calculation speed. By analyzing particle trajectories and relative geometric relationships, a hash set is constructed in advance to quickly calculate regional homogenization parameters. Finally, different particle characteristics in different regions of the pebble bed are compared.

Summary: Misregulation of neuronal autophagy is involved in age-related neurodegenerative diseases. Aging leads to a decrease in autophagosome formation rate and density along the axon, but an increase in autophagic vesicle maturation. Late aging results in a significant loss of acidified vesicles in the distal axon, while the efficient transport of autophagic vesicles in both proximal and distal axons is maintained during early aging. These findings suggest that aging differentially impacts distinct aspects of neuronal autophagy.

Summary: Underwater obstacles are known to be hotspots for various particulate matters in streams. This study examines the particle behaviors as they pass through a gap between two obstacles, and identifies the impact of gap length on the particle transport. The results show that the transport of particles is influenced by large-scale flow motions, and understanding these patterns can help in effective sampling and monitoring of organic and inorganic particles in aquatic environments.

Summary: This study developed a gene transfection strategy to track lysosome-based axonal transport in primary neurons with single-particle resolution. Various axonal transport models were observed, and the highly discontinuous nature of lysosome-based axonal transport was revealed. Furthermore, physical factors such as axonal structure and particle size were found to affect the velocity of particle transport in axons.

Summary: Despite having different mathematical definitions, both Radon and Hough transforms take an image as input and provide functions defined on a preassigned parameter space as output. The parameters in these spaces describe families of curves representing integration domains or curves to be detected. It is known that the Hough sinogram converges to the Radon sinogram as the discretization step in the parameter space approaches zero, but formal proof of this convergence has not been demonstrated.

Summary: This study investigated the potential of liposomes as an efficient drug-delivery system for treating disorders of the central nervous system. By optimizing the liposomes and conducting experiments in a rat model, the study confirmed successful retrograde transport to the spinal cord and dorsal root ganglia. Modifying the liposomes with different substances improved their transport efficiency, providing valuable insights for the future development of novel DDS targeting the CNS.

Summary: The classical circular Hough transform is effective for detecting some types of colorectal polyps, but tolerance is needed due to imperfect circular shape. The fuzzy Hough transform with Prewitt edge detection method was introduced to improve detection accuracy. The use of relative gradient-based thresholding and gradient-weighted voting prioritizes the gradient domain typical for polyp contours. Evaluation showed that gradient thresholding reduced calculation time and decreased the number of resulting circles outside the polyp's environment.

Summary: Many funding agencies have emphasized the importance of considering sex as a biological variable in experimental design to improve the reproducibility and translational relevance of preclinical research. Omitting the female sex from experimental designs in neuroscience and pharmacology can result in biased or limited understanding of disease mechanisms. This article provides methodological considerations for incorporating sex as a biological variable in in vitro and in vivo experiments, including the influence of age and hormone levels, and proposes strategies to enhance methodological rigor and translational relevance in preclinical research.
