To search for a potential solar proton event during this time and examine the solar cycle dependence, a high-precision carbon-14 analysis with annual resolution was conducted. We found no enhancement in carbon-14 around 1204 CE when prolonged low-latitude aurorae were observed in Kyoto, Japan, as recorded in Meigetsuki. Instead, we found a potential solar proton event in 1200-1201 CE, possibly associated with either the large sunspots or the red auroral events documented in this period. Reconstruction of solar cycles around the event suggested that this solar proton event occurred at the activity cycle's maximum. We also found that the solar cycles around this period were approximately seven to eight years, much shorter than those in the modern era, suggesting extremely high solar activity.","PeriodicalId":20707,"journal":{"name":"Proceedings of the Japan Academy.

Among these, photoredox catalysis has become a powerful method for generating radicals, but it typically relies on multistep electron- and energy-transfer processes that can limit the efficiency and design of reaction. Herein, we present the development of borate complexes that can be directly excited by light to generate carbon-centered radicals, which provides a simpler and more versatile alternative to the aforementioned methods. The initial boracene-based systems enable visible-light-driven cleavage of carbon-boron bonds to form alkyl radicals with strong reducing capability. To improve functional group compatibility, a second-generation complex prepared from widely available boronic acids was developed. These systems enable diverse reactions, including carbon-carbon bond formation and transformations of biologically relevant molecules. Furthermore, extension to deep-red and near-infrared light allows radical generation under lower-energy irradiation, which is advantageous for practical and biological applications. Finally, this approach enables a new type of photocaged molecule that releases bioactive compounds with precise spatial and temporal control, as demonstrated for acetylcholine in cellular and neural imaging. These studies highlight the direct excitation of borate complexes as a versatile platform for bridging synthetic chemistry and chemical biology.","PeriodicalId":20707,"journal":{"name":"Proceedings of the Japan Academy.

However, the widening gap between life expectancy and healthy life expectancy indicates that a growing population requires ongoing medical care and hospitalization. The development of a home-use telediagnostic system is a promising solution for improving the quality of life for patients and healthcare providers to extend a healthy lifespan and reduce the burden on clinicians. Such a system also holds the potential for rapid health assessments during emergency situations, where timely triage is critical. This study reviews recent progress in noninvasive, multimodal sensor patches capable of continuously monitoring vital signs and biomarkers via the skin. Furthermore, we explore the integration of machine learning for real-time, on-device data analysis as an edge system, enabling autonomous health feedback without reliance on the Internet. Although several technical challenges remain before practical implementation, these innovations may pave the way for a paradigm shift in conventional medical care.","PeriodicalId":20707,"journal":{"name":"Proceedings of the Japan Academy.

We used a bidirectional long short-term memory network to predict the five sleep stages using five different input feature combinations. The best performance was achieved with a model comprising six parameters, including cardiorespiratory variability features, with a balanced accuracy of 0.70 ± 0.05, Cohen's κ of 0.40 ± 0.11, and an F1 score of 0.63 ± 0.08. Deming regression and Bland-Altman analyses of the six major sleep parameters estimated by the model and those determined by PSG showed significant correlations (r = 0.426-0.781) with a low bias.

Historically, chromatin was assumed to fold into the 30-nm fiber and progressively arrange into larger helical structures, as described in the textbook model. However, over the past 15 years, extensive evidence including our studies has dramatically transformed the view of chromatin from a static, regular structure to one that is more variable and dynamic. In higher eukaryotic cells, chromatin forms condensed yet liquid-like domains, which appear to be the basic unit of chromatin structure, replacing the 30-nm fiber. These domains maintain proper accessibility, ensuring the regulation of DNA reaction processes. During mitosis, these domains assemble to form more gel-like mitotic chromosomes, which are further constrained by condensins and other factors. Based on the available evidence, I discuss the physical properties of chromatin in live cells, emphasizing its viscoelastic nature-balancing local fluidity with global stability to support genome functions.","PeriodicalId":20707,"journal":{"name":"Proceedings of the Japan Academy.
