AIMS Increased aortic stiffness is a fundamental manifestation of hypertension. However, the molecular mechanisms involved remain largely unknown. We tested the hypothesis that abnormal intrinsic vascular smooth muscle cell (VSMC) mechanical properties in large arteries, but not in distal arteries, contribute to the pathogenesis of aortic stiffening in hypertension, mediated by the serum respon...

This article presents a small-signal model for power-electronics converters that use typical control structure in wind energy applications: the double synchronous reference frame current control. The considers presence of unbalanced currents and voltages, analyzes their impact on frequency couplings converter. In addition, it is revealed that, negative-sequence voltage synchronization, converte...

Within power systems, high-power pulsewidth-modulated ac–dc converters are used in flexible ac transmission systems controllers and for interfacing renewable energy sources to the grid. These converters traditionally employed PI controllers designed in the synchronous -frame with decoupling of and axes. Recently, stationary -frame proportional-resonant (PR) controllers have been proposed. Thoug...

An attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.

Many users have shown increased postural instability while using Head-Mounted Displays (HMDs) as HMDs block their real-world vision. People with balance impairments are especially more affected by this they depend on visual cues to maintain balance. In addition, is a good indication of cybersickness according theory. research, we investigated how use additional improve stability. Through conduc...
