Bifurcation and complexity in a ratio-dependent predator-prey chemostat with pulsed input
      
In this paper, a three dimensional ratio-dependent chemostat model with periodically pulsed input is considered.
      
Increasing the impulsive period τ, the system undergoes a series of period-doubling bifurcation leading to chaos, which implies that the dynamical behaviors of the periodically pulsed ratio-dependent predator-prey ecosystem are very complex.
      
Nanocarbon-poly(methyl methacrylate) sols were prepared by pulsed laser ablation at the interface of target submerged in flowing liquid (PLA-IT/SFL) method, and the corresponding composite films were prepared by solution-casting.
      
In addition, the power gain under the continues wave condition is 14.2 dB with a power density of 4.1 W/mm, while under the pulsed wave condition, power gain reaches 14.4 dB with power density at 5.2 W/mm.
      
A complete performance test was done for the pulsed MAG welding power supply by using a computer testing platform.
      
Metal absorptivity in femtosecond pulsed laser ablation
      
In this paper, the effect of the absorptivity of metal on femtosecond pulsed laser ablation is investigated.
      
Based on this, a new two-temperature model is proposed to describe the femtosecond pulsed laser ablation with metal.
      
It is shown that the absorptivity plays an important role in the femtosecond pulsed laser ablation.
      
The results of this paper are helpful in choosing the best technical parameters in femtosecond pulsed laser ablation.
      
1050 W CW output and 133 W pulsed output are obtained in Shanghai Institute of Optics and Fine Mechanics, China.
      
DCs were pulsed with tumor cell lysate after being modified wth IL-23.
      
Changes in surface morphology of Ti6Al4V alloy and ZrO2-Y2O3 ceramic coating modified by high-intensity pulsed ion beams
      
The high-intensity pulsed ion beam (HIPIB) technique is developed to treat metallic and ceramic surfaces to improve materials performance.
      
Surface smoothing and reconstruction of titanium alloys and ZrO2-Y2O3 coatings have been observed as one of the typical outcome under high-intensity pulsed ion beam irradiation.
      
Study of bipolar pulsed plasma electrolytic carbonitriding on nanostructure of compound layer for a gamma Ti-Al alloy
      
The surface hardening of a gamma Ti-Al alloy by using bipolar pulsed nanocrystalline plasma electrolytic carbonitriding has been studied in this investigation.
      
Finally, the contribution percentage of the effective factors of the pulsed current was revealed, and the confirmation run showed the validity of the obtained results.
      
It's a zero power sub-critical neutron multiplying assembly driven by external neutron produced by a pulsed neutron generator.
