Abstract:
ABSTRACT The highly tangled magnetic field of a magnetar supports shear waves similar to Alfvén waves in an ordered magnetic field. Here, we explore if torsional modes excited in the stellar interior and magnetosphere can explain the quasi-periodic oscillations (QPOs) observed in the tail of the giant flare of SGR 1900+14. We solve the initial value problem for a tangled magnetic field that couples interior shear waves to relativistic Alfvén shear waves in the magnetosphere. Assuming stellar oscillations arise from the sudden release of magnetic energy, we obtain constraints on the energetics

Abstract:
Abstract Many regions of the universe are in a state of hot, magnetized, and ionized X-ray emitting plasmas. We numerically simulated the energy spectrum of this highly viscous and conductive system. Without magnetic field, the fluctuating plasma motion decays in a relatively large viscous scale l ν (∼1/k ν ). However, the magnetic field extends the viscous scale to the magnetic diffusivity one l η (∼1/k η ) yielding a unique energy spectrum. Numerical simulation shows that kinetic and magnetic energy spectrum are E V ∼ k −3.7 and E M ∼ k −0.85 in the extended viscous scale regime. To explain

With the rapid development of sixth-generation (6G) wireless networks and large-scale multiple-input multiple-output (MIMO) technology, the number of antennas deployed at base stations (BSs) has increased significantly, resulting in a high probability that users are in the near-field region. Note that it is difficult for the traditional far-field plane-wave model to meet the demand for high-precision beamforming in the near-field region. In this paper, we jointly optimize the power and the number of antennas to achieve the maximum energy efficiency for the users located in the near-field regio

Unified field theory is the long-sought means of tying together all known phenomena to explain the nature and behaviour of all matter and energy in existence. The quest for unification has been the perennial theme of modern physics. The belief that all physical phenomena can be reduced to simple and explained by a smaller number of laws is the central tenet of physics. Such a theory could potentially unlock all the secrets of nature and make a myriad of wonders possible, including such benefits as time travel and an inexhaustible source of clean energy, among many others.

The number parameter in B here is the observed number (the Heisenberg number) with a fluctuation.

Ethical dilemmas are rarely explored, and discussion of meta-ethical issues is almost entirely lacking.

Dynamo action creates a strong magnetic field with a complex structure, which becomes dominantly dipolar when solar activity is low.

Abstract:
We firstly compare the electric and magnetic polarizabilities of a spherical nanoparticle. We then calculate the electromagnetic heat transfer between a metallic particle and a semi-infinite substrate. We show that the power absorbed by the particle in the near field is due to the magnetic interaction. We then calculate the energy transfer between two metallic nanoparticles and compare the heat dissipated by Joule effect and eddy currents. We find that the heat dissipated due to the magnetic fields is the leading contribution to the heat power. Both calculations show that a number of near-fiel

Abstract:
The application of laser pulses with supershort duration of the order of 10 fs has recently been proposed [1,2] for enhancement of high order harmonic emission and subfemtosecond pulse production in the soft X-ray range. Such short driving pulses contain only a small number of optical cycles and therefore high energy photon bursts are generated due to atom ionization at rapidly increasing field amplitudes. It is obvious that the efficiency of this process becomes dependent on the concrete field distribution over the pulse or, in the other words, on the absolute phase of the optical field.

Abstract:
The increasing demand for more efficient energy conversion is making it extremely difficult for designers to develop next generation of centrifugal compressors. As the Reynolds number in centrifugal compressor operation decreases with increasing flight altitude, the efficiency degradation associated with it has been a key limitation to the energy conversion efficiency of aircraft engines. In this paper, the performance and internal flow field of a centrifugal compressor for a rear stage of a combined compressor are numerically simulated under different inlet conditions.

The results for different Rayleigh and Hartmann numbers show that the strength of the magnetic field has significant effects on the flow and temperature fields.

There are recurrent requests to establish a global taxation regime, or a cooperative solution, to transition away from fossil fuels as the main source of energy supply.
