Abstract A variety of autonomous oscillations in nature such as heartbeats and some biochemical reactions have been widely studied utilized for applications the fields bioscience engineering. Here, we report a unique phenomenon moisture-induced electrical potential on polymers, poly([2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide-co-acrylic acid), during diffusion water m...

We demonstrate the existence of nonlinear Tamm oscillations at the interface between a substrate and a one-dimensional waveguide array with either cubic or saturable, self-focusing or self-defocusing nonlinearity. Light is trapped in the vicinity of the array boundary due to the interplay between the repulsive edge potential and Bragg reflection inside the array. In the special case when this p...

pyrazine derivatives are important class of compounds with diverse biological and cytotoxic activities and clinical applications. in this study, b3 p 86 / 6 – 31 + + g * was used to compute and map the molecular surface electrostatic potentials of a group of substituted amides of pyrazine-2-carboxylic acids to identify common features related to their subsequent cytotoxicities. several statisti...

the main purpose of this study is the survey of the atmospheric low pressure effects at sea level oscillations in the qeshm channel. for this purpose, the curves of the pressure on the persian gulf and oman sea, during the passing of the atmospheric low pressure system, are extracted across the region. during the time of occurrence of these events, sea level oscillations in the coastal areas of...

Induced charge-density (ICD) oscillations at the Cu(111) surface caused by an external impurity are studied within linear response theory. The calculation takes into account such properties of the Cu(111) surface electronic structure as an energy gap for three-dimensional (3D) bulk electrons and a s − pz surface state that forms two-dimensional (2D) electron system. It is demonstrated that the ...
