A High-Modulus Dual-Cross-Linked Shell Promoting Phosphorus-Carbon Composites for Stable and High-Rate Lithium Ion Storage.

Phosphorus is considered an ideal anode material for lithium ion storage by virtue of its high theoretical capacity and moderate lithiation potential. However, issues such as large volume expansion of phosphorus leading to an electrical loss of contact and instability of the solid electrolyte interface hinder its practical performance. Improvement strategies that can effectively suppress volume expansion and provide stable electrical contacts are urgently needed.

Weighted Multi-modal Contrastive Learning based Hybrid Network for Alzheimer's Disease Diagnosis.

Multiple imaging modalities and specific proteins in the cerebrospinal fluid, providing a comprehensive understanding of neurodegenerative disorders, have been widely used for computer-aided diagnosis of Alzheimer's disease (AD). Given the proven effectiveness of contrastive learning in aligning multimodal representation, in this paper, we investigate effective contrastive learning strategies to learn better cross-modal representations for the integration of multi-modal complementary information. To enhance the overall performance in AD diagnosis, we construct a unified hybrid network that integrates feature learning and classifier learning into an end-to-end framework.

Revealing the underestimated role of Gram-positive bacteria in iron reduction within paddy soils.

Iron reduction in paddy fields is crucial for heavy metal migration and nutrient transformation. Gram-negative iron-reducing bacteria like Geobacter and Shewanella have been widely studied due to their strong extracellular electron transfer capabilities. In contrast, Gram-positive bacteria such as Bacillus and Clostridium are often labeled as weak exoelectrogens, leading to their contributions being overlooked.

Investigation of All Disease-Relevant Lysine Acetylation Sites in α-Synuclein Enabled by Non-canonical Amino Acid Mutagenesis.

Aggregates of α-synuclein (αS) are hallmarks of synucleinopathies, including Parkinson's Disease (PD) and Multiple System Atrophy (MSA). We have recently shown that αS lysine acetylation in the soluble monomer pool varies between healthy controls, PD, and MSA patients. To study the effects of lysine acetylation at all disease-relevant sites of αS, we first compared production of acetylated αS through either native chemical ligation or non-canonical amino acid (ncAA) mutagenesis.
