Changes in the climate system over recent decades have had profound impacts on mean state and variability of ocean circulation, while Nordic Sea overflow has remained stable volume transport during last two decades. The changes flux depend pressure difference at depth outlet both sides Greenland-Scotland Ridge (GSR). Combining satellite altimeter data reanalysis hydrological data, analysis foun...

INTRODUCTION The association of myasthenia gravis (MG) with thymoma is about 15%, which increases to about 35% in older patients (1,19). Thymomas represent nearly 50% of tumors in the anterior mediastinum and if large enough may cause mediastinal widening (12). The connection between the thymus gland and MG has led to the medical recommendation of a thymectomy, however, a thymectomy does not cu...

Ontology engineering is a hard and error-prone task, in which small changes may lead to errors, or even produce an inconsistent ontology. As ontologies grow in size, the need for automated methods for repairing inconsistencies while preserving as much of the original knowledge as possible increases. Most previous approaches to this task are based on removing a few axioms from the ontology to re...

[1] Despite the importance of hydromechanical effects in fault processes, not much is known about the interplay of chemical and mechanical processes, in part because the conditions are difficult to simulate in the laboratory. We report results from an experimental study of simulated fault gouge composed of rock salt sheared under conditions where pressure solution is known to operate. At slidin...

To improve the motor efficiency and expand actual external characteristic region of electric vehicle permanent magnet synchronous (PMSM) drive systems, optimal operation mapping torque to d-q axis current is usually applied. Nevertheless, it difficult deal with complex mechanism factors such as parameter saturation temperature change for traditional optimization method based on basic voltage eq...

The rheological properties of Earth's lower mantle are key for dynamics and planetary evolution. main rock-forming minerals in the bridgmanite (Br) smaller amounts ferropericlase (Fp). Previous work has suggested that large differences viscosity between these greatly affect bulk rock rheology. resulting effective rheology becomes highly strain-dependent as weaker Fp become elongated eventually ...

We show individual high resolution spectra of components A, B, and C of the nearby late-M type multiple system LHS 1070. Component A is a mid-M star, B and C are known to have masses at the threshold to brown dwarfs. From our spectra we measure rotation velocities and the mean magnetic field for all three components individually. We find magnetic flux on the order of several kilo-Gauss in all c...

These techniques are traditionally solved using a mathematical model of the machine with fixed parameters. However, in a real machine, the stator and rotor resistances are altered by temperature and the inductances are altered by the magnetizing current values that change for example when the machine is running in the flux weakening region or by an improper detuning between the flux and torque ...

In an El Niño event, positive SST anomalies usually appear in remote ocean basins such as the South China Sea, the Indian Ocean, and the tropical North Atlantic approximately 3 to 6 months after SST anomalies peak in the tropical Pacific. Ship data from 1952 to 1992 and satellite data from the 1980s both demonstrate that changes in atmospheric circulation accompanying El Niño induce changes in ...
