Large-scale Bias and Efficient Generation of Initial Conditions for Non-Local Primordial Non-Gaussianity

, 2012
We study the scale-dependence of halo bias in generic (non-local) primordial non-Gaussian (PNG) initial conditions of the type motivated by inflation, parametrized by an arbitrary quadratic kernel.

Improved primordial non-gaussianity constraints from measurements of galaxy clustering and the integrated Sachs-Wolfe effect [PDF]

, 2013
We present the strongest robust constraints on primordial non-Gaussianity (PNG) from currently available galaxy surveys, combining large-scale clustering measurements and their cross-correlations with the cosmic microwave background.

Land Use Conversion and Soil Properties in a Lowland Tropical Landscape of Papua New Guinea

Jurnal Manajemen Hutan Tropika, 2013
Land use conversion affects natural soil processes and can potentially decrease soils productivity.  A representative area was selected to study the effects of land use conversion in Unitech Campus, Southeastern lowlands of Papua New Guinea (PNG).  Area

Geoenvironmental GIS development to investigate Landslides and Slope Instability along Frontal zone of Central Himalaya

Natural Hazards Research, 2023
The Frontal Himalayan terrain comprises of Lesser Himalaya and Siwalik Hills; is highly susceptible to landslide disaster due to active tectonics, scrappy geology, steep slope, and reshaping geomorphology.

Halo statistics in non-Gaussian cosmologies: the collapsed fraction, conditional mass function, and halo bias from the path-integral excursion set method

, 2012
Characterizing the level of primordial non-Gaussianity (PNG) in the initial conditions for structure formation is one of the most promising ways to test inflation and differentiate among different scenarios.

Insecticide resistance status of Aedes aegypti and Aedes albopictus mosquitoes in Papua New Guinea

Parasites & Vectors, 2019
Background Aedes aegypti and Ae. albopictus are important vectors of infectious diseases, especially those caused by arboviruses such as dengue, chikungunya and Zika. Aedes aegypti is very well adapted to urban environments, whereas Ae.

GLM for Image Steganography Technique [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2013
An improvement to a Steganography method for hiding data using Gray Level Images is proposed in this paper. The method is an improvement over earlier method named Least Significant Bit (LSB).

Can we really measure fnl from the galaxy power spectrum?

, 2012
The scale-dependent galaxy bias generated by primordial non-Gaussianity (PNG) can be used to detect and constrain deviations from standard single-field inflation.

Nutrient dynamics under unmanaged rubber, cocoa, and oil palm plantations in a sandy soil under humid lowland tropical climatic conditions

International Journal of Environment, 2022
Changes in land use are an important issue in many farms that affect soil biological, chemical, and physical properties temporarily under cropping cycles or when the land is permanently allocated to perennial tree crops, e.g., in agroforestry. This study
