We prove that the Einstein equations for a spherically symmetric spacetime in Standard Schwarzschild Coordinates (SSC) close to form a system of three ordinary differential equations for a family of self-similar expansion waves, and the critical (k = 0) Friedmann universe associated with the pure radiation phase of the Standard Model of Cosmology is embedded as a single point in this family. Re...

Background. Evaluate the effectiveness of an infectious disease physician managed outpatient antibiotic therapy (OPAT) program. Methods. A retrospective chart review of 3754 patients from August 2011 through July 2013 who received intravenous OPAT through our program. Patients were either initiated in the hospital (HI) or in the office (OI). Results. 3754 patients were initiated or continued on...

Estimates from the current pulsar birth rate and the number of supernovae to account for the heavy-element abundance suggest that in total 10 to 10 isolated neutron stars exist in our Galaxy. Only a small fraction is detectable as young neutron stars due to their emission of thermal X-rays (for ∼10 years) or pulsed radio emission (for ∼10 years). Proposals that an old ”recycled” population of i...

CONTEXT Persistent pain and sensory disturbances following surgical treatment for breast cancer is a significant clinical problem. The pathogenic mechanisms are complex and may be related to patient characteristics, surgical technique, and adjuvant therapy. OBJECTIVE To examine prevalence of and factors associated with persistent pain after surgical treatment for breast cancer. DESIGN, SETT...

In a cool neutron star (T . 10 K) endowed with a rather high magnetic field (B & 10 G), a phase transition may occur in the outermost layers. As a consequence the neutron star becomes “bare”, i.e. no gaseous atmosphere sits on the top of the crust. The surface of cooling, bare neutron stars not necessary gives off blackbody radiation because of the strong suppression in the emissivity at energi...

Abstract The measurements of the bulk properties most isolated neutron stars (INSs) are challenging tasks. Tang et al. have developed a new method, based on equation state (EoS) star (NS) material constrained by observational data, to infer gravitational masses few INSs whose redshifts available. However, in that work, authors only considered constraints EoS from nuclear experiments/theories an...

We present spectroscopy and imaging with the Very Large Telescope (VLT) of the neutron star RX J1856.5−3754. Little is known about the nature of this source other than that it is a nearby hot neutron star. Our VLT spectrum does not show any strong emission or absorption features. With considerable care to photometric calibration, we obtain photometric measurements over the optical and ultra-vio...
