OBJECTIVES To determine the association of neighborhood socioeconomic status (SES) with bystander-initiated cardiopulmonary resuscitation (CPR) and patient outcomes of out of hospital cardiac arrests (OHCAs) in an Asian metropolitan area. METHODS We performed a retrospective study in a prospectively collected cohort from the Utstein registry of adult(More)
Few studies have analyzed the impact of liver cirrhosis, a clinically significant comorbid medical condition, on the mortality of patients with community-acquired bacteremia. We conducted an observational study of 839 consecutive community-acquired bacteremia patients who were hospitalized through the emergency department (ED). We compared the 30-day(More)
BACKGROUND Case reports have indicated that a tropical cyclone may increase Emergency Department (ED) visits significantly. STUDY OBJECTIVES To examine emergency health care demands across a series of tropical cyclones, and to build a predictive model to analyze a cyclone's potential effect. METHODS This was an observational non-concurrent prospective(More)
In this work, we present an investigation on the spatial entanglement entropies in the helium atom by using highly correlated Hylleraas functions to represent the S-wave states. Singlet-spin 1sns 1 S e states (with n = 1 to 6) and triplet-spin 1sns 3 S e states (with n = 2 to 6) are investigated. As a measure on the spatial entanglement, von Neumann entropy(More)
The surface formation oxide assists of visible to ultraviolet photoelectric conversion in α-In2Se3 hexagonal microplates has been explored. Hexagonal α-In2Se3 microplates with the sizes of 10s to 100s of micrometers were synthesized and prepared by the chemical vapor transport method using ICl3 as a transport agent. Many vacancies and surface imperfection(More)
By means of calculations based on density-functional theory (DFT), we have investigated the conversion of methane on two platinum atoms supported with a graphene-oxide sheet (Pt2/GO). In our calculations, a CH4 molecule can be adsorbed around the Pt atoms of the Pt2/GO sheet with adsorption energies within -0.11 to -0.53 eV; an elongated C-H bond indicates(More)
In the present work, we report an investigation on quantum entanglement in the doubly excited 2s 2 1 S e resonance state of the positronium negative ion by using highly correlated Hylleraas type wave functions, determined by calculation of the density of resonance states with the stabilization method. Once the resonance wave function is obtained, the(More)
