1Evolution of plasma parameters in an Ar-N2/He inductive plasma source with magnetic pole enhancement显示文摘Magnetic pole enhanced inductively coupled plasmas(MaPE-ICPs) are a promising source for plasma-based etching and have a wide range of material processing appUcations.In the present study Langmuir probe and optical emission spectroscopy were used to monitor the evolution of plasma parameters in a MaPE-ICP Ar-N_2/He mixture plasma.Electron density(n_e) and temperature(T_e),excitation temperature(T_(exc)),plasma potential(V_p),skin depth(δ) and the evolution of the electron energy probability function(EEPF) are reported as a function of radiofrequency(RF) power,pressure and argon concentration in the mixture.It is observed that n_e increases while T_e decreases with increase in RF power and argon concentration in the mixture.The emission intensity of the argon line at 750.4 nm is also used to monitor the variation of the 'high-energy tail' of the EEPF with RF power and gas pressure.The EEPF has a'bi-Maxwellian' distribution at low RF powers and higher pressure in a pure N_2 discharge.However,it evolves into a 'Maxwellian' distribution at RF powers greater than 70 W for pure N_2,and at 50 W for higher argon concentrations in the mixture.The effect of argon concentration on the temperatures of two electron groups in the 'bi-Maxwellian' EEPF is examined.The temperature of the low-energy electron group T_L shows a decreasing trend with argon addition until the 'thermalization' of the two temperatures occurs,while the temperature of high-energy electrons T_H decreases continuously.Maria YOUNUS N U REHMAN M SHAFIQ M NAEEM M ZAKA-UL-ISLAM M ZAKAULLAH 2017Plasma Science and Technology2017,19,2:2
2Minimally invasive and open gallbladder cancer resections: 30-vs 90-day mortality显示文摘BACKGROUND:Minimally invasive surgery is increasingly used for gallbladder cancer resection.Postoperative mortality at 30 days is low,but 90-day mortality is underreported.METHODS:Using National Cancer Database(1998-2012),all resection patients were included.Thirty-and 90-day mortality rates were compared.RESULTS:A total of 36 067 patients were identified,19 139(53%) of whom underwent resection.Median age was 71 years and 70.7% were female.Ninety-day mortality following surgical resection was 2.3-fold higher than 30-mortality(17.1% vs 7.4%).There was a statistically significant increase in 30-and 90-day mortality with poorly differentiated tumors,presence of lymphovascular invasion,tumor stage,incomplete surgical resection and low-volume centers(P<0.001 for all).Even for the 1885 patients who underwent minimally invasive resection between 2010 and 2012,the 90-day mortality was 2.8-fold higher than the 30-day mortality(12.0% vs 4.3%).CONCLUSIONS:Ninety-day mortality following gallbladder cancer resection is significantly higher than 30-day mortality.Postoperative mortality is associated with tumor grade,lymphovascular invasion,tumor stage,type and completeness of surgical resection as well as type and volume of facility.Naeem Goussous Motahar Hosseini Anne M Sill Steven C Cunningham 2017Hepatobiliary & Pancreatic Diseases International2017,16,4:2
