Summary: In this study, wood identification was conducted on Japanese and Chinese statues owned by the Museum of Fine Arts, Boston, USA. The results showed that the Japanese statues were made from Chamaecyparis obtusa, except for one statue that had a Cryptomeria japonica base. In contrast, the Chinese statue was made from Paulownia sp. hardwood.

Summary: Activating specific glutamatergic neurons in the brainstem produces a motor command resulting in global motor arrest. This arrest is distinct from defensive freezing and shows a pause-and-play pattern accompanied by reduced respiration and heart rate.

Summary: Although smoking might increase the risk of severe COVID-19, our previous study did not find strong evidence to support this conclusion. We also acknowledged that patients with diabetes or other chronic diseases could have worse outcomes in COVID-19, but this aspect was not investigated in our study as we had published separate research on diabetes. Due to limited sample size and medical records, our study could not encompass multiple factors. Nonetheless, we hope our study serves as a useful and meaningful pilot study for future research.

Summary: In this paper, a variant of the Chan-Vese (CV) segmentation model with rectilinear anisotropy is studied. The existence of minimizers in the 2-phases case and their relation to the (anisotropic) Rudin-Osher-Fatemi (ROF) denoising model are shown. The analysis demonstrates that in the case of a piecewise constant on rectangles image (PCR function), there exists a minimizer of the CV functional that is also piecewise constant on rectangles over the same grid as the original image. In the multiphase case, minimizers of the CV multiphase functional share the same property when the initial image is a PCR function. A multiphase and anisotropic version of the Truncated ROF algorithm is also investigated and compared with minimizers of the multiphase anisotropic CV functional.

Summary: Researchers have developed a copper-catalyzed dehydrogenative Chan-Lam coupling reaction that enables efficient construction of sulfilimines under biomolecule-compatible conditions. This method offers mild reaction conditions and broad substrate compatibility, making it suitable for late-stage functionalization of complex peptides and bioconjugation reactions.

Summary: Sulfondiimines, an underexplored scaffold in organic chemistry, have been synthesized efficiently through a copper-catalyzed method presented in this study. The synthesis allows the preparation of diversified sulfondiimines with various functional groups, and it was also used to generate an aza-analogue of an EphB4 inhibitor featuring a sulfondiimine-based pharmacophore.

Summary: Researchers reconstructed the habitat and lifestyle of the last bacterial common ancestor (LBCA) by analyzing 146 LCBA protein families, indicating that the LBCA was rod-shaped and the first lineage to diverge from the ancestral bacterial stem was most similar to modern Clostridia, followed by other autotrophs that harbor the acetyl-CoA pathway.

Summary: The Cu-catalyzed oxidative cross-coupling of N- and O-nucleophiles with aryl boronic acids (the Chan-Lam reaction) is a valuable method for preparing aniline and phenol derivatives, with high chemoselectivity and mild reaction conditions. In addition, we have developed the analogous carbon-carbon bond forming variant for the first time.

Summary: This study investigated the relationship between ileal microbes and body weight in Muscovy ducks and explored the underlying mechanisms. The results showed that certain microbes were closely associated with duck growth, while others were negatively correlated with body weight. Additionally, the expression of tight junction proteins and inflammatory factors exhibited some changes in the high-weight group. These findings are important for the development of next-generation probiotics and strategies to manipulate the gut microbiota to promote growth performance in the duck industry.

Summary: This study focuses on designing a resilient data structure under the Faulty-RAM model for maintaining a tree. The data structure can store a dynamic tree with a root that can be updated. It supports various queries, such as resilient (weighted) level ancestor queries, lowest common ancestor queries, and bottleneck vertex queries, with a worst-case time complexity of O(delta) per operation.

Summary: Whole genome duplication (WGD) is an important event in evolution, generating new genes and potentially promoting survival during mass extinctions. Paddlefish and sturgeon, sister lineages, show genomic evidence of ancient WGD. Although the duplications appear to be independent, they actually stem from a shared WGD event over 200 million years ago, prior to the Permian-Triassic extinction. The shared WGD is masked by lineage divergence before the completion of rediploidization.
