The OGLE database is revisited to investigate in more detail the properties of the Fourier parameters. Methodological improvements led us to identify a clear separation among High–Amplitude δ Scuti (HADS), RRc and RRab stars. The bimodal distribution of the R21parameter in HADS stars is explained as a contamination effect from RRc stars: there is evidence that all stars with 0.20< P <0.25 d are...

In this paper, we elaborate on an idea initially developed by Weitzman (1998) that justifies taking the lowest possible discount rate for far-distant future cash flows. His argument relies on the arbitrary assumption that when the future rate of return of capital (RRC) is uncertain, one should invest in any project with a positive expected net present value. We examine an economy with a risk-av...

Some results are given from the comparison with observations of a large number of hydrodynamic pulsation models: (1) Linear pulsation calculations are adequate for the determination of the masses of RRd stars; (2) the Fourier phase parameter 4>31 measures the luminosity-to-mass ratio L/M1.81 for RRc stars; (3) most of the w Cen RRc stars seem to be evolved, as has previously been suggested; (4)...

The Accreditation Council for Graduate Medical Education (ACGME) has the mission of improving the quality of health care in the United States by ensuring and improving the quality of graduate medical education experience for physicians in training. The ACGME oversees 27 Residency Review Committees (RRC), including the Neurology Residency Review Committee (NRRC). Each RRC functions as the ACGME ...

RESULTS: At this writing, all published papers on RRC are based on small number of patients with short-term followup. Nevertheless, they have demonstrated the technical feasibility of RRC with encouraging perioperative outcomes. Compared to open radical cystectomy (ORC), RRC appears to be associated with decreased blood loss, hospital stay and analgesic requirement. These advantages are also fo...

Masses, temperatures, and absolute luminosities are proposed for a large sample of RRc stars in the globular cluster w Centauri. Our technique uses three observed quantities: period, relative luminosity, and Fourier phase CP31' interpreting them in the light of linear and hydrodynamic pulsation models. The masses we obtain agree with those of the RRd stars in other clusters, and our derived par...

BACKGROUND The objective of this meta-analysis was to compare the clinical safety and efficacy of robotic right colectomy (RRC) with conventional laparoscopic right colectomy (LRC). METHODS A literature search was performed for comparative studies reporting perioperative outcomes of RRC and LRC. The methodological quality of the selected studies was assessed. Depending on statistical heteroge...
