Abstract Fixed-time artificial insemination (FTAI) provides a practical and feasible option for commercial stud breeders to implement AI into their herds, as 100% of the herd can be inseminated at predetermined time. FTAI suit many whether they are inseminating small numbers or whole herd. We investigated effects sire inseminator on pregnancy birth outcomes following Angus cows. Three sires; na...

We propose to realize adiabatic topological spin and valley pumping by using silicene, subject to the modulation of an in-plane ac electric field with amplitude Ey and a vertical electric field consisting of an electrostatic component and an ac component with amplitudes and . By tuning and , topological valley pumping or spin-valley pumping can be achieved. The low-noise valley and spin current...
