During the liquid metal extraction reaction between a Nd-Dy-Fe-B magnet and Mg, Nd rapidly diffuses out of magnet, whereas Dy is not extracted due to with matrix formation Dy2Fe17 phase. In addition, theDy2O3 phase exists at grain boundaries. Until now, only effect Dy2O3 on has been reported. this study, from was investigated in Mg. The during Mg (RE2Fe14B) first examined using thermodynamical ...

Skyline queries have recently attracted a lot of attention for its intuitive query formulation. It can act as a filter to discard sub-optimal objects. However, a major drawback of skyline is that, in datasets with many dimensions, the number of skyline objects becomes large and no longer offer any interesting insights. To solve the problem, k-dominant skyline queries have been introduced, which...

In intact animals and humans, increases in locomotor speed are usually associated with decreases in step cycle duration. Most data indicate that the locomotor central pattern generator (CPG) shortens cycle duration mainly by shortening the durations of extensor rather than flexor phases of the step cycle. Here we report that in fictive locomotion elicited by electrical stimulation of the midbra...

We investigate the possibility of enhancement parity-violation signal in bouncing cosmology. Specifically, we are interested deciding which phase should generate most significant signals. find that dominant contribution comes from phase, while contraction has a smaller contribution. Therefore, cosmology can enhance signals during phase. Moreover, since highest energy scale cosmology, also probe...

Vaginal ultrasonography of uterine peristalsis during the follicular phase of the menstrual cycle demonstrates an increasing frequency and intensity of subendometrial and myometrial peristaltic waves as the follicular phase progresses. During this time the numbers of contraction waves with a fundo-cervical direction decrease considerably in favour of waves of contraction with a cervico-fundal d...
