In the motor drive system of electric vehicles, there are some nonlinear factors, such as the deadtime and the conduction voltage drop of Joint / Bone Support switching devices, which will generate low-order harmonics of the stator current and the torque ripple.The frequency of the harmonic may coincide with the natural frequency of the motor, so r

Abstract Seed size/weight plays an important role in determining crop yield, yet only few genes controlling seed size have been characterized in soybean.Here, we perform a genome-wide association study and identify a major quantitative trait locus (QTL), named GmSW17 (Seed Width 17), on chromosome 17 that determine soybean seed width/weight in natu

Porous Copper (Cu) was brazed to Cu plates using Cu-9.7Sn-5.7Ni-7P amorphous filler metal.The effects of brazing parameters on the porous Cu and brazed joints were investigated.The furnace brazing temperatures employed were 660 °C and 680 °C, and the holding times were 10 and 15 min.After brazing, the microstructure was analyzed using Sca

Persistent left superior vena cava is the most common congenital anomaly of thoracic venous return, which results when the left anterior cardinal vein fails to regress.A 41-year-old African American male with a history of an unspecified childhood cardiac murmur presented to the emergency department with congestive heart failure exacerbation reveali

Treatment of chronic heart failure (CHF) often can be a rather difficult task.Proper selection of therapy and Smart Watch strict adherence to the recommendations is vital in these patients.Unfortunately, in practice we often encounter with free interpretation of the recommendations, which leads to tactical errors and reduce the effectiveness of tre
