OBJECTIVE Few studies have investigated the relationship between asthma and suicidality-related outcomes in the world. We sought to investigate the association between asthma and risk of non-fatal self-harm in a large national sample. METHODS Cases aged 10years and over were identified from Taiwan's National Health Insurance Research Database with a new primary diagnosis of asthma (ICD-9:493)...
In this paper, we present some new lower and upper bounds for the modified Randic index in terms of maximum, minimum degree, girth, algebraic connectivity, diameter and average distance. Also we obtained relations between this index with Harmonic and Atom-bond connectivity indices. Finally, as an application we computed this index for some classes of nano-structures and linear chains.
Total harmonic distortion (THD) is the most popular power quality index. Two problems with THD are ambiguities in its definition and utilization of it in some conditions. In order to solve these problems, a number of modifications have been suggested for THD definition and some new indices have been introduced. In this paper, these indices are briefly reviewed, then are investigated, analyzed a...
Recent developments in tissue harmonic imaging and intravenous contrast agents have enhanced left ventricular endocardial border delineation (EBD). In a total of 48 patients with poor quality images, apical 4- and 2-chamber views were obtained with fundamental, tissue harmonic and contrast harmonic imaging with or without intravenous Levovist, an air-filled contrast agent. The left ventricle (L...
We derive the structural relations between nested harmonic sums and the corresponding Mellin transforms of Nielsen integrals and harmonic polylogarithms at weight w = 6. They emerge in the calculations of massless single–scale quantities in QED and QCD, such as anomalous dimensions and Wilson coefficients, to 3– and 4–loop order. We consider the set of the multiple harmonic sums at weight six w...
BACKGROUND Most previous studies of long-term mortality risk following self-harm have been conducted in Western countries with few studies from Asia. AIMS To investigate suicide and non-suicide mortality after non-fatal self-harm in Taipei City, Taiwan. METHOD Prospective cohort study (median follow-up 3.3 years) of 7601 individuals presenting to hospital with self-harm (January 2004 to Dec...
OBJECTIVE The authors examined the accuracy of certain neuropsychological tests in the prediction of harm resulting from self-neglect in cognitively impaired seniors who lived alone. METHODS The study included 130 participants, aged 65 and older, who scored less than 131 on the Dementia Rating Scale. Neuropsychological tests were administered at baseline, resulting in eight predictive scores....
