In standard quantum mechanics, the Hamiltonian describing physical system is generally Hermitian, so as to ensure that has real energy spectra and system’s evolution unitary. recent years, it been found non-Hermitian Hamiltonians with parity-time (<inline-formula><tex-math id="Z-20220827100836">\begin{document}${\cal {PT}}$\end{document}</tex-math><alternatives><graph...

COVID-19 Pandemic that started from the end of 2019 and developed in 2020 has changed international world order. That felt by all countries world, including Indonesia. The rapid raising casualties made government taking a lockdown policy. It was meant to protect their citizens prevent more massive spreading. protection is not only applied for country but also living abroad like Indonesian migra...

Reduction of carbon emissions from tropical deforestation and forest degradation is being considered a cost-effective way of mitigating the impacts of global warming. If such reductions are to be implemented, accurate and repeatable measurements of forest cover change and biomass will be required. In Papua New Guinea (PNG), which has one of the world's largest remaining areas of tropical forest...

BACKGROUND The potential for an expanded HIV epidemic in Papua New Guinea (PNG) demands an effective, evidence-based and locally-appropriate national response. As sexually transmitted infections (STIs) may be important co-factors in HIV transmission nationally, it is timely to conduct a systematic review of STI prevalences to inform national policy on sexual health and HIV/STI prevention. MET...

BACKGROUND Male circumcision (MC) is a well-established component of HIV prevention in countries with high HIV prevalence and heterosexually driven epidemics. Delivery and monitoring of MC programs are reliant on good quality MC data. Such data are often generated through self-reported MC status surveys. This study examined self-reported MC status in comparison with genital photographs from men...

Efforts to incentivize the reduction of carbon emissions from deforestation and forest degradation require accurate carbon accounting. The extensive tropical forest of Papua New Guinea (PNG) is a target for such efforts and yet local carbon estimates are few. Previous estimates, based on models of neotropical vegetation applied to PNG forest plots, did not consider such factors as the unique sp...
