2Late biliary complications in human alveolar echinococcosis are associated with high mortality显示文摘AIM:To evaluate the incidence of late biliary complications in non-resectable alveolar echinococcosis(AE)under long-term chemotherapy with benzimidazoles.METHODS:Retrospective analysis of AE patients with biliary complications occurring more than three years after the diagnosis of AE.We compared characteristics of patients with and without biliary complications,analyzed potential risk factor for biliary complications and performed survival analyses.RESULTS:Ninety four of 148 patients with AE in Zurich had non-resectable AE requiring long-term benzimidazole chemotherapy,of which 26(28%)patients developed late biliary complications.These patients had a median age of 55.5(35.5-65)years at diagnosis of AE and developed biliary complications after 15(8.25-19)years of chemotherapy.The most common biliary complications during long-term chemotherapy were late-onset cholangitis(n=14),sclerosing cholangitis-like lesions(n=8),hepatolithiasis(n=5),affection of the common bile duct(n=7)and secondary biliary cirrhosis(n=7).Thirteen of the 26 patients had undergone surgery(including 12 resections)before chemotherapy.Previous surgery was a risk factor for late biliary complications in linear regression analysis(P=0.012).CONCLUSION:Late biliary complications can be observed in nearly one third of patients with non-resectable AE,with previous surgery being a potential risk factor.After the occurrence of late biliary complications,the median survival is only 3 years,suggesting that late biliary complications indicate a poor prognostic outcome.Pascal Frei Benjamin Misselwitz Meher K Prakash Alain M Schoepfer Bettina M Prinz Vavricka Beat Müllhaupt Michael Fried Kuno Lehmann Rudolf W Ammann Stephan R Vavricka 2014World Journal of Gastroenterology2014,20,19:5
3Optimization of Mo/Cu(In,Ga)Se2/CdS/ZnO Hetero-Junction Solar Cell Performance by Numerical Simulation with SCAPS-1D显示文摘The paper presents a one-dimensional simulation study of chalcopyrite Cu(In,Ga)Se2(CIGS)solar cells,where the effects of the variation of CIGS,CdS,and ZnO layers are presented.Additionlly the influence of the variation of doping and the defects density of shallow uniform donors and acceptors types are also presented.The analyse of the simulation results shows that recombination inside the space charge region(SCR)decrease more our CIGS solar cell model performance.We also found that the electrical parameters increase with increasing CIGS absorber doping density exception of JSC values that reach their maximum at 1016cm-3 and decrease due to recombination of charge carriers in the p-n junction particularly the recombination inside the SCR.We also stressed the fact that the effects of shallow uniforme donor density is very low on the performance of our CIGS solar cell model is important because it will allow to control the width of space charge region from shallow uniform acceptors defect density that has a strong influence on the different electrical parameters.Yet,good optimization of performance of the CIGS-based solar cell necessarily passes though a good control of the space charge region width and will constitute a boosting perspective for the preparation of our next paper.We contact that the results obtained of the numerical simulation with SCAPS-1D show a good agreement comparatively of the literature results.The simulation of our CIGS solar cell presents best performances if the values of the absorber layer thickness is in the range of 0.02 to 0.03μm,the buffer layer thickness is in the range of 0.02 to 0.06μm and the defects density of shallow uniform acceptors types is in the range of 1015 to 1017cm-3.Adama Zongo Daouda Oubda Soumaïla Ouédraogo Marcel Bawindsom Kébré Alain Diasso Issiaka Sankara Boureima Traore François Zougmoré Zacharie Koalga Frédéric Ouattara 2021材料科学与工程(中英文B版)2021,11,4:2

5Noise Feedback Coding Revisited:Refurbished Legacy Codecs and New Coding Models显示文摘Noise feedback coding(NFC) has attracted renewed interest with the recent standardization of backward-compatible enhancements for ITU-T G.711 and G.722.It has also been revisited with the emergence of proprietary speech codecs,such as BV16,BV32,and SILK,that have structures different from CELP coding.In this article,we review NFC and describe a novel coding technique that optimally shapes coding noise in embedded pulse-code modulation(PCM) and embedded adaptive differential PCM(ADPCM).We describe how this new technique was incorporated into the recent ITU-T G.711.1,G.711 App.III,and G.722 Annex B(G.722B) speech-coding standards.Stéphane Ragot Balázs Kvesi Alain Le Guyader 2012ZTE Communications2012,10,2:2

14Secret key exchange in ultralong lasers by radiofrequency spectrum coding显示文摘We propose a new approach to the generation of an alphabet for secret key exchange relying on small variations in the cavity length of an ultralong fiber laser.This new concept is supported by experimental results showing how the radiofrequency spectrum of the laser can be exploited as a carrier to exchange information.The test bench for our proof of principle is a 50-km-long fiber laser linking two users,Alice and Bob,where each user can randomly add an extra 1-km-long segment of fiber.The choice of laser length is driven by two independent random binary values,which makes such length become itself a random variable.The security of key exchange is ensured whenever the two independent random choices lead to the same laser length and,hence,to the same free spectral range.Alessandro Tonello Alain Barthelemy Katarzyna Krupa Vincent Kermene Agnes Desfarges-Berthelemot Badr Mohamed Shalaby Sonia Boscolo Sergei K Turitsyn Juan Diego Ania-Castanon 2015Light(Science & Applications)2015,4,1:1
