We propose a scenario in which dark energy and dark matter are described in a unified manner. The ultralight pseudo-Nambu-Goldstone (pNG) boson, A, naturally explains the observed magnitude of dark energy, while the bosonic supersymmetry partner of the pNG boson, B, can be a dominant component of dark matter. The decay of B into a pair of electron and positron may explain the 511 keV γ ray from...

A new data hiding method via PNG images based on Shamir’s (k, n)-threshold secret sharing scheme is proposed. The coefficients of the polynomial used by the Shamir’s method are taken as carriers to carry given data. The data to be hidden then are transformed into partial shares and embedded into the alpha-channel plane of a cover PNG image. Undesired white noise created in the resulting stego-i...

We consider the polynuclear growth model (PNG) in 1+1 dimension with flat initial condition and no extra constraints. Through the Robinson-Schensted-Knuth (RSK) construction, one obtains the multilayer PNG model, which consists of a stack of non-intersecting lines, the top one being the PNG height. The statistics of the lines is translation invariant and at a fixed position the lines define a p...

The concept that developed countries should pay developing countries not to deforest and thus reduce carbon emissions from deforestation and degradation (REDD) has been gaining attention over the last few years. Despite the lack of binding commitments from the recent United Nations Climate Change Conference in Copenhagen, the Copenhagen Accord acknowledges the value of REDD and intends to mobil...

The study analyzes the place of religion in national collective memory and changes that have taken field connection with modernization emergence modern nationstates India Papua New Guinea (PNG). In case PNG, we look at Christianization process modernization, while India, analyze use Hinduism forming identity. Both cases are analyzed selected material culture specific localities they show ongoin...

OBJECTIVE The objective of this study was to evaluate the level of appropriateness of prescribing to outpatients in selected healthcare facilities in Papua New Guinea (PNG), using health department guidelines as the benchmark. METHODS A prospective study was carried out at Losuia Health Centre (LHC), Alotau Provincial Hospital (APH) and Port Moresby General Hospital (PMGH) in PNG. At each set...

The hypothesis underlying this current work is that fresh juice expressed from Papua New Guinea (PNG) medicinal plants (succus) will inhibit human Cytochrome P450s (CYPs). The CYP inhibitory activity identified in fresh material was compared with inhibition in methanol extracts of dried material. Succus is the most common method of traditional medicine (TM) preparation for consumption in PNG. T...

The dynamics of Plasmodium vivax infection is characterized by reactivation of hypnozoites at varying time intervals. The relative contribution of new P. vivax infection and reactivation of dormant liver stage hypnozoites to initiation of blood stage infection is unclear. In this study, we investigate the contribution of new inoculations of P. vivax sporozoites to primary infection versus react...
