Any value of a cosmological constant is allowed. We investigate some particular examples of motion, namely a straight flight and a circular trajectory, and we derive the corresponding radiation patterns and the mass loss of the rockets. We also demonstrate the absence of "gravitational aberration" ...
We designed a head-mounted three-photon microscope for imaging deep cortical layer neuronal activity in a freely moving rat. Delivery of high-energy excitation pulses at 1,320 nm required both a hollow-core fiber whose transmission properties did not change with fiber movement and dispersion comp...
where \({\mathcal{L}}\) is the Lagrangian, ∂x denotes \(\frac{\partial }{\partial x}\), ψ(x, t) is a field operator for electrons, m is an effective mass, and we set ℏ = 1 in the main text. The CDW order parameter is $$V(x-vt)=2\Delta \cos (2{k}_{F}(x...

Effect of moving mass-center and Stark shift on evolution of field entropy is studiedthrough the generalization of J-C model. Our study shows that the moving mass-centercan make the period of evolution of field entropy change.The period of the entropy isshorter than that in which the Stark ...

NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
The fact that the neutron has a rest mass results in a significantly lower energy as compared to photons with nm wavelength. As a result neutrons are an excellent probe for the study of low energy excitations, such as phonons or molecular rotations as well as the study of diffusion via, ...
Körper", or "On the Electrodynamics of Moving Bodies", 鈥The special theory of relativity postulates that the speed of light is always constant in a vacuum. However, recent experiments [5, 6, 7] indicate that the photon has a very small but nonzero mass, which will affect the speed ...
Units and/or devices according to one or more example embodiments may also include one or more storage devices. The one or more storage devices may be tangible or non-transitory computer-readable storage media, such as random access memory (RAM), read only memory (ROM), a permanent mass sto...
