Super-resolution in high contrast media [PDF]
, 2014 A mathematical theory is developed to explain the super-resolution and super-focusing in high contrast media. The approach is based on the resonance expansion of the Green function associated with the medium. It is shown that the super-resolution is due to sub-wavelength resonant modes excited in the medium which can propagate into the far-field.

Formation of charmonium states in heavy ion collisions and thermalization of charm [PDF]
Eur.Phys.J. A29 (2006) 15-18, 2005 We examine the possibility to utilize in-medium charmonium formation in heavy ion interactions at collider energy as a probe of the properties of the medium. This is possible because the formation process involves recombination of charm quarks which imprints a signal on the resulting normalized transverse momentum distribution containing information ...

In-medium modifications of the S11(1535) resonance and eta photoproduction [PDF]
Phys.Rev. C68 (2003) 044601, 2003 We investigate the influence of possible in-medium modifications of the S11(1535) in eta photoproduction in nuclei. Besides Fermi motion, Pauli blocking and binding effects also collisional broadening is accounted for. The in-medium width is obtained from a realistic resonance-hole model.

Enigmatic Formations Found in Routine Orthopantomography (OPG) Examinations: A Case Report
Diagnostics, 2023 We describe two clinical cases of occasional radiographic findings on orthopantomography (OPG) that were performed routinely, for which the definitive diagnosis may be uncertain. After an accurate remote and recent anamnesis, for reasons of exclusion, we

Excess noise for coherent radiation propagating through amplifying random media [PDF]
Phys.Rev. A60 (1999) 4059, 1999 A general theory is presented for the photodetection statistics of coherent radiation that has been amplified by a disordered medium. The beating of the coherent radiation with the spontaneous emission increases the noise above the shot-noise level. The excess noise is expressed in terms of the transmission and reflection matrices of the medium, and ...

The volatility of Bitcoin and its role as a medium of exchange and a store of value
Empirical Economics, 2021 Bitcoin is designed as a peer-to-peer cash system. To work as a currency, it must be stable or be backed by a government. In this paper, we show that the volatility of Bitcoin prices is extreme and almost 10 times higher than the volatility of major ...

Klestadt’s Cyst with Radiographic Contrast Medium: A Case Report [PDF]
Journal of Clinical and Diagnostic Research, 2014 Klestadt’s cyst is commonly known as Nasolabial cyst, is a rare non-odontogenic, soft-tissue, developmental cyst. It accounts for around 0.7% of cysts of the jaws and 2.5% of the nonodontogenic cysts.

Contrast Medium Hypersensitivity: A Large Italian Study with Long-Term Follow-Up
Biomedicines, 2022 Hypersensitivity reactions (HRs) to contrast media (CM) are a major problem. We compared differences of HRs to iodinated contrast media (ICM) versus gadolinium-based contrast media (GBCM), collecting data on prevalence, type, latency and severity ...
