Loss of body armour, sometimes including a reduction in or loss of pelvic spines, is an adaptation observed in many isolated freshwater populations.Pelvic reduction in sticklebacks has previously been associated with recurrent, but variant, deletions within pelvic enhancer regions PelA and PelB, which regulate expression of the homeodomain transcri
In the motor drive system of electric vehicles, there are some nonlinear factors, such as the deadtime and the conduction voltage drop of 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 resonance may occur on
The Task Segment Framework (TSF) is a tool to analyze full typing flows of translation tasks as keylogged with timestamps recorded for keydown, keyup, mouse clicks and moves, and actions performed in other applications.The TSF assumes that intentional pauses flag stretches where subjects concentrate on unrecorded cognitive processes such as plannin
Fe3O4 nanoparticles (NPs) with a continuous and mesoporous silica (m-SiO2) shell were synthesized using a one-step method, sourcing silica from rice husk ash (RHA).The rice husk was thermally treated to obtain ash, from which silica was extracted as sodium silicate and precipitated by pH reduction.This silica powder, combined with iron chloride sal
