Carried by the wind, dust particles (微粒) fromplaces such as the Sahara Desert can float halfwayaround the world before settling to the ground. Asthe plastics abandoned by humans break down intotiny pieces in the environment, they, too, travelthrough the atmosphere. Now scientists are a step...
AgNPs are known for interfering in virus particles' binding to the host cell, preventing their entry. However, the exact antiviral action has not yet been fully understood [12]. The interaction of AgNPs with cells is complex, and studies need to elucidate the cytotoxic potential of nanoparticles...
When all particles from the IN and OUT states are reduced we obtain the vacuum expectation value of a time-ordered product of field operators. This allows us to use perturbative methods for defining the amplitudes by making T-contractions between the kinetic part obtained from the reduction formal...
Now imagine this great drop of water with all of these jiggling particles stuck together and tagging along with each other. The water keeps its volume; it does not fall apart, because of the attraction of the molecules for each other. If the drop is on a slope, where it can move from...
The flow was less strong and as he rubbed the side of his hand against the planking of the skiff, particles of phosphorus floated off and drifted slowly astern. "He is tiring or he is resting, "the old man said."Now let me get through the eating of this dolphin and get some rest ...
The frequency dependence is far more complicated, and is related to the resonances of the plate: at resonance, much smaller actuation amplitudes are needed to move the particles. For controlled manipulation, we want to keep the particle displacement relatively constant for all notes. To do this,...
Before the collisions, all the energy is carried by the beam particles in longitudinal phase space. But after the collisions, the final state particle production in the transverse plane carries finite transverse energy (ET), which is an event-by-event observable and it is closely related to ...
reverted back to separate cl::Context for each OpenCL device, as the shared Context otherwise would allocate extra VRAM on all other unused Nvidia GPUs removed Debug and x86 configurations from Visual Studio solution file (one less complication for compiling) fixed bug that particles could get too...
litre of seawater may contain more than 100bn virus particles, and a kilo of dried soil ten times that number. Altogether, according to calculations on the back of a very big envelope, the world might contain 1031 of the things—that is one followed by 31 zeros, far outnumbering all ...
We collected 35,579 micrographs that contained ~7.3 million single particles and performed extensive data processing (Extended Data Fig. 3a–c). Single-particle classification and refinements resulted in an overall reconstruction of the Pol II–SPT6–Elongin complex at a nominal resolution of 2.6...
