Figure 1: HB-NBP molecule. Finally, the molecule was mounted on top of an atomic defect bound to one elbow (see Fig. 3). Once mounted concentrically on its atomic pinning centre, HB-NBP was ...

Scientists have just plotted changes in Earth's axis through laboratory measurements. To do this, they constructed the world's most stable ring laser. Previously, scientists were only able to track ...

Earth's axial precession is a gyroscopic wobble, analogous to a spinning top, causing its axis of rotation to trace a cone over time. The primary cause of Earth's precession is the gravitational ...

Using a complex model to perform a theoretical calculation based on a U.S. Geological Survey, Richard Gross of NASA's Jet Propulsion Laboratory (JPL) has determined that by changing the distribution ...

In a “normal” electrocardiogram (ECG), the transition of the QRS axis in the precordial leads occurs between leads V 3 and V 4 (i.e., there is a dominant S in V 3 and a dominant R in V 4).
