The Laplace transform can be regarded as a transform from the time domain to the frequency domain. For example, applying the Laplace transform, the function x(t) may be transformed into a function of the complex variable p, where
(a) In situ test set up for stretching a microfiber with dog-bone shape. Snapshot of the tensile process of PμSL printed microfiber with section size of (b) 20 μm (c) 60 μm. The first frames after fracture are also presented. (The figures (b) and (c) share the same scale...
We study strongly attractive p-orbital fermions on optical lattices.We map the system Hamiltonian to an effective spin Hamiltonian.We use a variational approach and a linear spin wave theory to map the phase diagram.The results can be experimentally tested using cold atomic systems....
The periodic table has columns and rows of varying sizes. The reason behind the table’s odd shape becomes clear if it is divided into sections, or blocks, representing the atom’s energy sublevel being filled with valence electrons. 元素周期表中各列以及各行所包含的元素个数有差异。如果根据元...
Also, the LED or IRED has a large P–N-junction area whose shape is tailored to the application. Nowadays, the discovery of white LED has made it a material of extreme importance due its very low power consumption. However, still challenges remain for marketization of white light LED that ...
33 by measuring absorption at 600 nm (Number of flashes: 10; Settle time: 50 ms) and luminescence emission (Attenuation: none; Settle time: 50 ms; Integration time: 200 ms) with a Tecan Infinity® or ClarioStar plate reader in between 10-min cycles of agitation (orbital, 180...

the rostrum. This purpose of this strange appendage is not clear. It may have had a hydrodynamic function, since the shape ofDoryaspissuggests it was an active swimmer, probably feeding on plankton. Or it may have been used to stir up the bottom mud or sand, to find crustacea or other...
