Light-matter interaction provides a powerful means to control mechanical excitation in the nanoscale. The efficiency of this interaction reaches maximum at optical resonance. By understanding and designing the electromagnetic resonance of nanostructures, we can manipulate the electromagnetic field distribution as desired, with the benefits of enhancing the field strength and squeezing the field...

Motivated by recent experiments, we study theoretically the full counting statistics of radiation emitted below the threshold of parametric resonance in a Josephson-junction circuit. In contrast to most optical systems, a significant part of emitted radiation can be collected and converted to an output signal. This permits studying the correlations of the radiation. To quantify the correlations...

We present one-dimensional local potentials with an absolute reflection at a given energy value which can be above barriers. The corresponding energy dependence of a reflection coefficient exhibits resonance behavior. The inversion technique provides the potentials with specified widths of reflection resonances, their number and positions. The multichannel systems (exact models) with a complete...

The first issue of Magnetic Resonance in Medicine appeared in March 1984, which is 30 years ago this month. Despite all the remarkable changes over the years, both in our field and in publishing, the commitment by our authors and reviewers to scientific, technical, and clinical innovation and excellence has remained unchanged. In its history, the journal and the ISMRM have worked with three pub...

In this paper, we prove the boundedness of all solutions for the equation x + n 2 x + φ(x) + g (x)q(t) = 0, where n ∈ N, q(t) = q(t + 2π), φ(x) and g(x) are bounded.

Introduction. Waveguides have been successfully used to generate magnetic resonance images at 7 Tesla for whole-body systems [1]. From these results, it has been established that waveguides are only suitable for 7T systems with wide bores of al least 60 cm. This is mainly due to the cut-off frequency of the cylindrical waveguides used. To overcome this limitation a parallel-plate waveguide was ...

Magnetic resonance imaging (MRI) has been used to image the in utero fetus for the past 3 decades. Although not as commonplace as other patient-oriented MRI, it is a growing field and demonstrating a role in the clinical care of the fetus. Indeed, the body of literature involving fetal MRI exceeds 3000 published articles. Indeed, there is interest in accessing even the healthy fetus with MRI to...

The present study investigates the optical characteristics and the spectral and angular responses of a Kretschmann surface plasmon resonance (SPR) sensor configuration that is widely used in biological and chemical sensing applications. In order to examine the influence of wave interference and optical properties of thin films on angular variation of reflectance at different incident angles, th...

The use of spin-echoes has been employed in an Echo-Planar Spectroscopic Imaging (EPSI) sequence to collect multiple phase encoded lines within a single TR in a Multi-Echo-based Echo-Planar Spectroscopic Imaging technique (MEEPSI). Despite the T₂ dependence on the amplitude of the spin-echoes, the Full Width at Half Maximum (FWHM) of the derived multi-echo Point Spread Function (PSF) is shown t...
