BACKGROUND AND OBJECTIVE: Heated, humidified high-flow nasal cannula (HHHFNC) is commonly used as a noninvasive mode of respiratory support in the NICU. The safety and efficacy of HHHFNC have not been compared with other modes of noninvasive support in large randomized trials. The objective was to assess the efficacy and safety of HHHFNC compared with nasal continuous positive airway pressure (...

Unmanned aerial vehicles (UAVs) have the potential to carry resources in support of search and prosecute operations. Often to completely prosecute a target, UAVs may have to simultaneously attack the target with various resources with different capacities. However, the UAVs are capable of carrying only limited resources in small quantities, hence, a group of UAVs (coalition) needs to be assigne...

Hunt et al. (2) and Norton (4) showed that the northern root-knot nematode, Meloidogyne hap/a Chitwood, increased the incidence of bacterial wilt in alfalfa. Hunt et al. (2) also f o u n d t h e b a c t e r i a l wilt organism, Corynebacterium insidiosum (McCuU) H. L. Jens., in plant tissue that had been inoculated only with the bacteria. This would indicate that the role of M. hapla is somethi...

The atomic structure of dioctahedral 2:1 phyllosilicate edge surfaces was calculated using pseudopotential planewave density functional theory. Bulk structures of pyrophyllite and ferripyrophyllite were optimized using periodic boundary conditions, after which crystal chemical methods were used to obtain initial terminations for ideal (110)and (010)-type edge surfaces. The edge surfaces were pr...

INTRODUCTION The number of primary care physicians in the United States continues to lag behind the number of uninsured people. There has been a growing demand for medical students to improve their self-efficacy, comfortableness, attitude, and interest in working with the underserved and in primary care. This study aims to discern whether volunteering at a student-run, free healthcare clinic ha...

The persistence of criminal activity is well documented. While such serial correlation may be evidence of social interactions in the production of crime, it may also be due to the persistence of unobserved determinants of crime. Moreover, there are good reasons to believe that, particularly over a short time horizon, there may actually be a negative relationship between crime rates in a particu...

People who exhibit unhealthy lifestyle behaviours are at greater risk of severe disease outcomes, hospitalisation and mortality when infected with COVID-19. Accordingly, it is suggested that those higher levels cardiorespiratory fitness engage in regular physical activity (PA) associated a reduced adverse outcomes. Although improved physiological function may protect individuals against acute C...

The extant choice literature has proposed different non-compensatory rules as a more realistic description of consumers’ choice than a standard compensatory model. Some research has further suggested a two-stage sequential decision process of non-compensatory consideration and then compensatory choice, where the determinants of each stage may differ. Some aspects of non-compensatory choice mode...

The study by Stefanadis et al. in this issue indicates that treatment with a variety of statins reduces the release of heat from atherosclerotic plaques in the human coronary artery. This observation suggests that statins exert a beneficial effect on the inflammatory process that exists in the vascular wall in a variety of acute coronary syndromes. The finding that this effect was most pronounc...

OBJECTIVE Clinicians often overestimate the probability of a disease given a positive test result (positive predictive value; PPV) and the probability of no disease given a negative test result (negative predictive value; NPV). The purpose of this study was to investigate whether experiencing simulated patient cases (ie, an 'experience format') would promote more accurate PPV and NPV estimates ...
