摘要:Denisovans are a hominin group primarily known through genomes or proteins, but their precise morphological features remain elusive because of the fragmentary nature of the discovered fossils. Here, we report 95 endogenous proteins retrieved from a nearly complete cranium from Harbin, China, dating to at least 146,000 years ago and previously assigned to a new species, Homo longi. This individual has three Denisovan-derived amino acid variants and clusters with Denisova 3, suggesting that the ...

摘要:Diffraction of atoms from surfaces provides detailed insights into structures, interactions, and dynamical processes. However, the method is currently limited to measurements in reflection-diffraction through materials has only been demonstrated for subatomic particles and is an outstanding challenge for atoms. In this work, we diffract helium and hydrogen atoms at kilo-electron volt energies through single-layer graphene at normal incidence. Despite the atoms' high kinetic energy as well as c...

摘要:An inertial confinement fusion experiment, carried out at the National Ignition Facility, has achieved ignition by generating fusion energy exceeding the laser energy that drove the experiment. Prior to the experiment, a generative machine learning model that combines radiation hydrodynamics simulations, deep learning, experimental data, and Bayesian statistics was used to predict, with a probability greater than 70%, that ignition was the most likely outcome for this shot.

摘要:Cyclo[N]carbons, molecular rings consisting solely of N carbon atoms, have previously been studied in the gas phase and on surfaces at cryogenic temperatures, but they are generally considered too reactive to be studied under ambient laboratory conditions. In this study, we report the synthesis of a cyclo[48]carbon catenane, in which the C48 ring is protected by being threaded through three other macrocycles. This cyclo[48]carbon [4]catenane is stable enough for spectroscopic characterization ...
