An Evolving Spacetime Metric Induced by a `Static' Source
Martin Land
In a series of recent papers we developed a formulation of general relativity in which spacetime and the dynamics of matter evolve with a Poincaré invariant parameter . In this…
Universal lower bound on orbital periods around central compact objects
Shahar Hod
It is proved, using the curved line element of a spherically symmetric charged object in general relativity and the Schwinger discharge mechanism of quantum field theory, that the…
What can a detected photon with a given gravitational redshift tell us about the maximum density of a compact star?
Shahar Hod
Far away observers can in principle bound from below the dimensionless maximum-density parameter of a compact star by measuring the gravitational redsh…
Charged Gauss-Bonnet black holes supporting non-minimally coupled scalar clouds: Analytic treatment in the near-critical regime
Shahar Hod
Recent numerical studies have revealed the physically intriguing fact that charged black holes whose charge-to-mass ratios are larger than the critical value $(Q/M)_{\text{crit}}=\…
Extremal black holes have external light rings
Shahar Hod
It is proved that spherically symmetric extermal black holes possess at least one external light ring. Our remarkably compact proof is based on the dominant energy condition which…
Implementation and Evaluation of a System for Assessment of The Quality of Long-Term Management of Patients at a Geriatric Hospital
Erez Shalom, Ayelet Goldstein, Roni Wais +3
Background The use of a clinical decision support system for assessing the quality of care, based on computerized clinical guidelines (GLs), is likely to improve care, reduce costs…
