The case of two weakly coupled spins selectively irradiated by amplitude-modulated on-resonance pulses is discussed. Since the Hamiltonian of the case considered is a sum of two mutually commuting, time-dependent operators, it is possible to find a transformation matrix describing the net effect of...
A method of performing magnetization transfer contrast (MTC) using a pulse sequence based on a series of onresonance binomial pulses preceding a convention... MD Hollett,AM Aisen,NY Hong,... - 《Magnetic Resonance Imaging》 被引量: 33发表: 1994年 Optimum setting of binomial pulses for magnet...
This Letter presents a simple, efficient approach for high surface-enhanced Raman scattering by one-step controllable fabrication of hierarchical structures (nanoparticles + subwavelength ripples) on silicon substrates in silver nitrate solutions using femtosecond double pulses based on nanoscale electron dynam...
In this sense, these X-ray spectroscopies including XAS, HERFD-XAS, XES, RIXS and XPS through probing their specific energy-dependent inherent resonance can realize a comprehensive understanding of various dynamic events. Most notably, the RIXS technique can probe those electronic transition of a ...
The highest interaction efficiency takes place at the resonance condition when the frequencies of the interacting modes are equal. However, due to the finite spectral widths of the S- and W- modes, their interaction is still quite efficient when the modes are detuned. Moreover, magnon-phonon ...
Dissipative soliton resonance in a passively mode-locked figure-eight fiber laser The generation of mode-locked rectangular pulses operating in dissipative soliton resonance (DSR) region is demonstrated in an erbium-doped figure-eight fi... Shi-Ke,Wang,Qiu-Yi,... - 《Optics Express》 被引量: ...
A general method is described for the accumulation of nuclear magnetic resonance proton spectra in water and other proton-containing solvents, which minimizes the spectral distortions usually associated with the intense solvent resonance. The technique involves the addition of a relaxation agent, which di...
Demonstration 3 – Cross-resonance characterization Having covered the manipulation of a single qubit, we now demonstrate how users can control the entanglement of multiple qubits. There are several methodologies for entangling qubits. In the OQC system, qubits are entangled through a ‘...
Many studies have since chosen a similar repetition frequency in USN pulses presumably based on this work, but there is little physiological basis for introducing this pulsed scheme26,28,29. King et al. did not find PRF to increase stimulation success, while others have noted that burst ...
the sensing head. Strain and temperature variation of the FBGs can be measured by the shift in the resonance frequencies resulting from the change in the total cavity length (2ΔL), mainly because of the relation between the change in the Bragg wavelength and the high dispersion of the CF...
