  摘要：Semiaquatic taxa, including humans, often swim at the air-water interface where they waste energy generating surface waves. For fully marine animals however, theory predicts the most cost- efficient depth- use pattern for migrating, air- breathing species that do not feed in transit is to travel at around 2 to 3 times the depth of their body diameter, to minimize the vertical distance traveled while avoiding wave drag close to the surface. This has rarely been examined, however, due to depth m...

  摘要：Despite 96 million years of evolution separating humans and rodents, 11 closely related the 13 reproductive tract- specific orthologous genes in mice, form highly conserved syntenic gene clusters indicative of conserved, combined critical functions. Further, despite significant progress toward a nonhormonal male contraceptive targeting the protein encoded by one of these genes, epididymal peptidase inhibitor (EPPIN), and associations found between mutations in EPPIN and an increased risk of ma...
• Direct simulation and machine learning structure identification unravel soft martensitic transformation and twinning dynamics AI翻译

  摘要：Phase transition between ordered phases has garnered attention from the viewpoint of materials science as well as statistical physics. One interesting example is martensitic transformation and the resulting formation of twin structures, in which atoms or molecules that form one crystalline phase move in a concerted and diffusionless manner toward another crystalline phase. Recently martensitic transformation has been observed experimentally also in various soft materials. However, the complex ...
• Electrocatalytic nitrate reduction using iron single atoms for sustainable ammonium supplies to increase rice yield AI翻译

  摘要：Increasing food production and ensuring drinking water safety have always been a focus of attention, especially for people in underdeveloped regions of the world. Traditional excessive fertilizer applications have increased crop yield but also caused groundwater nitrate pollution. Agricultural irrigating water is an important reservoir for nitrogen (N) (e.g., nitrate) accumulation after fertilization. Ammonium (NH4+-N) is a more readily absorbed N form by rice than nitrate (NO3--N). In this st...

  摘要：The high-temperature superconducting cuprates host unidirectional spin- and charge- density-wave orders that can intertwine with superconductivity in nontrivial ways. While the charge components of these stripes have now been observed in nearly all cuprate families, their detailed evolution with doping varies across different materials and at high and low temperatures. We address this problem using nonperturbative determinant quantum Monte Carlo calculations for the three-band Hubbard model. U...
• Dissection revisited: Deciphering bodies and ancient medical texts AI翻译

  摘要：Unlike traditional approaches to Greco- Roman medicine, which are strongly based on textual evidence, we addressed some problems, currently debated by historians, through a technique borrowed from the biological sciences: We reenacted an ancient anatomical dissection of the abdominal wall, the peritoneal cavity, and its organs (as described by Galen during the 2nd century CE, in his major treatise Anatomical Proceedings). Our aim was to clarify incongruencies about the text itself-considering ...

  摘要：Synaptic vesicles (SVs) store and transport neurotransmitters to the presynaptic active zone for release by exocytosis. After release, SV proteins and excess membrane are recycled via endocytosis, and new SVs can be formed in a clathrin- dependent manner. This process maintains complex molecular composition of SVs through multiple recycling rounds. Previous studies explored the molecular composition of SVs through proteomic analysis and fluorescent microscopy, proposing a model for an average ...
