High-dielectric-constant materials are technologically important because of their nonlinear properties. We find that the third-order susceptibility varies in the range 10^-14--10^-12m^2·V^-2 for ion-implanted semiconductor plasmas, which is in good agreement with previous results. It is found that the presence of SDDC in ion-implanted semiconductor plasma modifies the characteristic properties of the material.展开更多

We surveyed the incidence of all deaths that occurred from 2018 through 2021 which came through the Marion County Coroner’s Office, Indiana. The data was then divided into two halves. According to the data, the leading manner of death in the first half and second half was accidental. This study revealed a total of 8732 cases: 3817 of them were observed to be accidental, 3092 natural, 956 homicide, 689 suicide, and 178 were undetermined. There were initially 318 drug overdose related deaths in 2018 and they increased to 2163 by 2021. In 2018, the number of deaths due to fentanyl related overdoses increased from 195 to 799 in 2021. This research will contribute to the forensic science field by providing information about the manner of death and fentanyl trends in Marion County over the last four years.展开更多
