Abstract The current research on gear system dynamics mainly utilizes linear spring damping model to calculate the contact force between gears. However, this linear model cannot correctly describe the energy transfer pro...

"Heart-brain interaction is by nature bidirectional, and then, it is sensible to expect the heart, via the autonomic nervous system (ANS), to induce changes in the brain. Respiration can originate differentiated ANS stat...

"We study the properties of a soliton crystal, a bound state of several optical pulses that propagate with a fixed temporal separation through the optical fibres of the proposed approach for generation of optical frequen...

      In this paper we prove that the function  is i-open if it is injective, surjective and i-continuous from i-compact topological space  into -space. Further, we define and find the relationship among some i-se...

Ultra-massive white dwarfs are powerful tools used to study various physical processes in the asymptotic giant branch (AGB), type Ia supernova explosions, and the theory of crystallization through white dwarf asteroseism...

By reaction between stearic acid (SA) and a di-epoxidized oligomeric poly(ethylene glycol) under stoichiometric conditions, an amphiphilic β-hydroxyester (β-HE) bearing pendant alkyl chains was obtained with a typical ...
