We propose a quantum oscillation experiment by which the rotation of an underdoped YBa(2)Cu(3)O(6+x) sample about two different axes with respect to the orientation of the magnetic field can be used to infer the shape of the in-plane cross-section of corrugated Fermi surface cylinder(s). Deep corrugations in the Fermi surface are expected to give rise to nodes in the quantum oscillation amplitu...

Based on the MHD Alfven wave oscillation model for the kHz quasi periodic oscillation (QPO), we investigate the comparisons between the model and the four sample sources, Sco X-1, 4U1608−52, 4U1735-44 and 4U1728−34, and obtained that the maximum upper and lower kHz QPO frequencies coincide and occur at about 1300 Hz. Moreover, the theoretical ratio between the maximum kHz QPO frequency and the ...

BACKGROUND High-frequency oscillation (HFO) is a widely used lung-protective ventilatory strategy in paediatric and neonatal acute lung injury. Its safe and effective use has been hindered by inadequate recruitment of the lung during oscillation and, until recently, the lack of an adequately powered oscillator for use in adult practice. METHODS We present data from three adolescents with seve...

To enhance the inertial response and damping capability during transient events this paper investigates an improved active power control for variable speed wind turbines. The optimized power point tracking (OPPT) controller, which swings the turbine operating point from the maximum power point tracking (MPPT) curve to the virtual inertia control (VIC) curves by the frequency deviation, is propo...

In this paper an analytical model of the oscillation frequency of a differential CML ring oscillator is proposed. The model helps to choose the bias current value to optimize speed, and it is useful to estimate the oscillation frequency changes associated with the bias current change and to process tolerances. Moreover, it allows to relate the propagation delay of a gate evaluated in a ring osc...

The K2K experiment observes indications of neutrino oscillation: a reduction of nu(mu) flux together with a distortion of the energy spectrum. Fifty-six beam neutrino events are observed in Super-Kamiokande (SK), 250 km from the neutrino production point, with an expectation of 80.1(+6.2)(-5.4). Twenty-nine one ring mu-like events are used to reconstruct the neutrino energy spectrum, which is b...

Zhang et al interpret the mixed-layer energy budget in models as showing that "ocean dynamics play a central role in the AMO." Here, we show that their diagnostics cannot reveal the causes of the Atlantic Multidecadal Oscillation (AMO) and that their results can be explained with minimal ocean influence. Hence, we reaffirm our findings that the AMO in models can be understood primarily as the u...

Overhead transmission lines are influenced by different factors which are mostly electrical and mechanical. These factors can cause problems for lines, distortions in network and outage of line. In designing transmission lines mechanical properties are evaluated after selecting a suitable conductor and clearance with regard to electrical properties. In lines designing, an important mechanical p...
