They support the concept of convection columns aligned with the rotation axis that concentrate magnetic flux into four strong lobes near 卤 65 掳 latitude, and of rising plumes at the poles that are associated wit
The relative role of each climatic subcomponent of the acting forcings (on top) is indicated. The lower axis shows timescale in years. AMV, Atlantic Multidecadal Variability; DO, Dansgaard–Oeschger event; e, eccentricity; ENSO, El Niño–Southern Oscillation; HE, Heinrich event; NAO, North ...
在模型坐标系里,所有的位置都是相对于模型坐标系的原点来定义滴). In object space, positions of vertices are interpreted relative to a local origin. Consider a spaceship model. The origin of the model is probably going to be
Figures 2a–2c shows the correlation matrices of atmospheric density and solar indices, atmospheric density and the FISM2 data set, and atmospheric density and the OMNI data set (y-axis) as a function of all-times, quiet-times, storm-times, storm main phase, and storm recovery phase (x-...
In this work, we show that the formation of hydrogen bond ladder between hydroxy of adjacent NPG molecule columns restricts the rotation of molecules at low temperature, while its breaking significantly lowers the activation barrier. The hydrogen bond and its correlation to the transition temperature ...
Indeed for an increasingly small distance the period of rotation does not change, it is always 24 hours for the Earth. Thus, at the North and South poles, the rotational speed is actually zero, because this is the point where the Earth's axis of rotation meets its surface. This means ...
Rayleigh waves are a type of surface wave that propagate near the Earth’s surface as ripples and cause a rotation that can be either prograde (along the direction of propagation) or retrograde (against the direction of propagation). They are also called ground roll due to the n...
The transformative potential of AI in education is substantiated by recent research. Studies show that AI models based on Transformer architectures can diagnose student misconceptions in physics with accuracy comparable to human experts (Demirezen et al.,2023). Similarly, advanced systems such as the...
The position and angles were adjusted by a linear motor, a high load lab jack (Newport 281), and a two-axis tilt and rotation platform (Newport P100-P). The short-circuit charge QSC and open-circuit voltage VOC of the samples were measured by a Keithley 6514 electrometer in a glove ...
Crystal structure of NPG in (a) the monoclinic phase at low temperature and (b) cubic phase at high temperature. The light-yellow-shaded circle represents one NPG molecule. The green lines in (a) and green arrows in (b) demonstrate the stationarity and rotation of the NPG molecule, respect...
