Summary: This study reports a method for high-resolution afterglow patterning of crystalline materials via cooperative organic vapo- and photo-stimulation. The crystalline materials can transition from a crystalline state to an amorphous state through oxidation and melting, enabling the formation of afterglow patterns. This method allows for repeated readout of the afterglow patterns under ambient conditions, and holds potential for high-speed fabrication of anti-counterfeiting media.

Summary: In this study, a cross-resolution perceptual experiences transfer framework is proposed for categorizing high-resolution aerial photos. By leveraging the perceptual features from low-resolution aerial photos to enhance the feature selection of high-resolution ones, the technique for categorizing a rich variety of high-resolution aerial photos is achieved.

Summary: We present a self-supervised learning approach for high-resolution photographic enhancement. Our model learns the parameters of photographic filters to improve the quality of photos by making them similar to high-quality references. Experimental results show that loss functions based on feature-extraction networks achieve better quality than pixel-comparison metrics.

Summary: In this study, we used Fast-SIM imaging system to investigate the dynamic changes in mitochondrial structure under specific photo-oxidation stress induced by Chlorin-e6 and light irradiation. The results showed that the mitochondrial structure underwent significant remodeling and shortening after 60-80 seconds of irradiation, accompanied by fusion of adjacent inner membrane cristae and organelle swelling. Prior to these alterations, there was heightened dynamics within the mitochondrial network, characterized by events such as mitochondrial fission, rapid formation of tubular prolongations, and fluctuations in cristae structure.

Summary: The rapid proliferation of planktonic algae induced by eutrophication and climate warming make algae dissolved organic matter an important source of dissolved organic matter in surface waters. The intracellular organic matter from Microcystis aeruginosa has lower aromaticity and higher photo-sensitive activity compared to Suwannee River fulvic acid. Light radiation results in the composition transformation of the organic matter, forming less aromatic and more saturated recalcitrant dissolved organic carbon.

Summary: Photochromic compounds are utilized to develop neuron surrogates for neuromorphic engineering in wetware. The photochromic behaviors of (E)-3,4,6-trichloro-2-(p-diazenil)-phenol (t-DZH) and its conjugated phenoxide base (t-DZ) in various media have been experimentally investigated. The results suggest that t-DZH and t-DZ can serve as molecular probes and potential ingredients for implementing pacemaker neurons that communicate optically in wetware.

Summary: Low viscosity photo-curable benzoxazines (BZs) were designed and synthesized for stereolithography 3D printing, leading to thermally polymerized polybenzoxazines (PBZs) with high T-g and flexural modulus values. The formulated photoprintable resins were used in high-resolution projection micro-stereolithography printing, allowing for complex PBZ 3D structures to be achieved. These findings advance the efficient fabrication of high-performance thermosets for demanding engineering applications.

Summary: DLP-based 3D printing is a useful tool for manufacturing hydrogel structures, but it requires the use of water-soluble photo-absorbers to improve resolution. However, current photo-absorbers are not efficient or water-soluble. This study presents a method to convert non-water-soluble photo-absorbers to water-soluble nanoparticles, resulting in improved resolution and transparency for printed hydrogel structures, expanding the potential applications of hydrogels.

Summary: In this study, Kim et al. utilized various sequencing techniques to uncover the high-resolution translatome and transcriptome of SARS-CoV-2, identifying a novel translation initiation site TIS-L in the leader sequence. They found that TIS-L serves as a translation enhancer for ORF S and as translation suppressors for other ORFs, providing unique insights into the regulation of the SARS-CoV-2 translatome.
