BACKGROUND Non-fatal self-harm is one of the most frequent reasons for emergency hospital admission and the strongest risk factor for subsequent suicide. Repeat self-harm and suicide are key clinical outcomes of the hospital management of self-harm. We have undertaken a comprehensive review of the international literature on the incidence of fatal and non-fatal repeat self-harm and investigated...

Harmonic sliding analysis (HSA) is a dynamic spectrum analysis [1] in which the next analysis interval differs from the previous one by including the next signal sample and excluding the first one from the previous analysis interval. Such a harmonic analysis is necessary for time-frequency localization [2] of analysed signal given peculiarities. Using the well-known Fast Fourier transform (FFT)...

The harmonic index H(G) of a graph G is the sum of 2 d(u) + d(υ) over all edges uυ of G, where d(u) denotes the degree of a vertex u in G. In this paper, we give the minimum value of H(G) for graphs G with given minimum degree δ(G) ≥ 2 and characterize the corresponding extremal graph. Furthermore, we prove a best-possible lower bound on the harmonic index of a triangle-free graph G with arbitr...

We study properties of the harmonic measure of balls in large critical Galton–Watson trees whose offspring distribution is in the domain of attraction of a stable distribution with index α ∈ (1, 2]. Here the harmonic measure refers to the hitting distribution of height n by simple random walk on the critical Galton–Watson tree conditioned on non-extinction at generation n. For a ball of radius ...

This project proposed the new distortion power quality index to replace the previously proposed index. Its computation was carried out based on the load composition rate (LCR) and Euclidean norm of total harmonic distortions (THDs) of the measured voltage and current waveforms at the point of common coupling (PCC). Based on the proposed PQI, the harmonic pollution ranking, which indicates how m...

BACKGROUND Little is known about outcomes after self-harm in East Asia. AIMS To investigate mortality after self-harm in a Taiwanese population. METHOD Between 2000 and 2003, 1083 individuals who self-harmed were identified through a population self-harm register in Nantou County, Taiwan, and followed until 2007 for date and cause of death on a national mortality database. RESULTS In tota...

objective: self-harm was classified to show forms like non-suicidal self injury and indirect risky behaviors and drug abuse. the aims of this study were to compare suicidal tendencies indexes and difficulty in emotion regulation skills in mixed groups of adolescents with direct and indirect forms of self-harm. methods: in a casual-comparative design from population of delinquent adolescents det...
