Dynamical social phenomena have been modeled using differential systems employed in mathematical models of epidemiology. In Misra (2012), an epidemiological model is used to study the “spread” of two political parties. In ...
Zinc oxide (ZnO) films were synthesized using spray pyrolysis using glass as substrate at substrate temperature of 400°C. The precursor used is an aqueous solution of ZnCl2. The deposition was done in ambient conditions. ...

The prokaryotic diversity associated with serpentinization-driven Manleluag Hyperalkaline (pH
11) Spring in Pangasinan, Philippines was investigated. DNA extracted directly from the sediment
samples was used to construct ...
In this study, a system of delay differential equations arising from
a three-species model with two predators feeding on a single prey is
considered. It is assumed that the prey population grows logistically
in the ...
We consider a symmetric system of delay differential equations arising from a model of two
mutually delay-coupled semiconductor lasers. The system is described using the Lang-Kobayashi rate
equations whose basic solutions ...
In this paper, we propose Differential Evolution - Simulated Annealing (DESA),
a hybrid optimization algorithm for fitting autoregressive models to data. The addition of a
new strategy based on parabolic estimation to ...
In a high-rainfall, landslide-prone region in this tropical mountain region, a landslide database was constructed from high resolution satellite imagery (HRSI), local reports and field observations. The landslide data was ...

Island snail diversity is truly amazing for archipelagic country such as Philippines with the
prospect of high level of endemicity. The Northern Luzon alone encompasses the two largest
mountain chains with different ...
Cancer is characterized by unregulated growth of certain cells in the body, often
leading to a rapid growth of tumors in vital organs. Various treatments have been proposed and
given to cancer patients, including ...
