A Dark Core in Abell 520

The Astrophysical Journal, 2007
The rich cluster Abell 520 (z=0.201) exhibits truly extreme and puzzling multi-wavelength characteristics. It may best be described as a "cosmic train wreck." It is a major merger showing abundant evidence for ram pressure stripping, with a clear offset in the gas distribution compared to the galaxies (as in the bullet cluster 1E 0657-558).

A SOLUTION OF SUN'S $520 CHALLENGE CONCERNING $\frac{520}{\pi}$ [PDF]

International Journal of Number Theory, 2013
We prove a Ramanujan-type formula for 520/π conjectured by Zhi-Wei Sun. Our proof begins with a hypergeometric representation of the relevant double series, which relies on a recent generating function for Legendre polynomials by Wan and Zudilin. After showing that appropriate modular parameters can be introduced, we then apply standard techniques ...

Is there an alignment of quasars near NGC 520 ? [PDF]

Symposium - International Astronomical Union, 1987
Three statistical tests applied to 65 UV excess objects in the field of NGC 520 lead to no detection of any significant alignment.

Big boys don't cry: Depression and men [PDF]

, 2008
Men are a numerical minority group receiving a diagnosis of, and treatment for, depression. However, community surveys of men and of their mental health issues (e.g. suicide and alcoholism) have led some to suggest that many more men have depression than

Reliability modeling of a 1-out-of-2 system: Research with diverse Off-the-shelf SQL database servers [PDF]

, 2007
Fault tolerance via design diversity is often the only viable way of achieving sufficient dependability levels when using off-the-shelf components. We have reported previously on studies with bug reports of four open-source and commercial off-the-shelf ...

520 The immune landscape of pediatric tumors [PDF]

Regular and young investigator award abstracts, 2020
Background It is now well established that the immune system has a substantial role in controlling cancer growth and progression. Immunotherapy is quickly coming to the forefront of cancer treatment,however the implementation of immunotherapy in pediatric solid cancers, which classically display a low mutational load, is hindered by insufficient ...

Incidence of esophageal injury after pulmonary vein isolation in patients with a low body mass index and esophageal temperature monitoring at a 39 °C setting

Journal of Arrhythmia, 2015
Background: Esophageal injury following catheter ablation of atrial fibrillation (AF) is reported to occur in 35% of patients. Even with a low energy setting (20–25 W), lesions develop in 10% of patients.

Acquisition of the pulmonary venous and left atrial anatomy with non-contrast-enhanced MRI for catheter ablation of atrial fibrillation: Usefulness of two-dimensional balanced steady-state free precession

Journal of Arrhythmia, 2015
Background: Usually, the pulmonary venous and left atrial (PV–LA) anatomy is assessed with contrast-enhanced computed tomographic imaging for catheter ablation of atrial fibrillation (AF).

Radio observations of the merging galaxy cluster Abell 520 [PDF]

Astronomy & Astrophysics, 2018
Context. Extended synchrotron radio sources are often observed in merging galaxy clusters. Studies of the extended emission help us to understand the mechanisms in which the radio emitting particles gain their relativistic energies. Aims.

Visualization of the radiofrequency lesion after pulmonary vein isolation using delayed enhancement magnetic resonance imaging fused with magnetic resonance angiography

Journal of Arrhythmia, 2015
Background: The radiofrequency (RF) lesions for atrial fibrillation (AF) ablation can be visualized by delayed enhancement magnetic resonance imaging (DE-MRI).
