1Bivariate Wavelet Analysis of Asia Monsoon and ENSO显示文摘This paper employs some recently developed bivariate wavelet analysis techniques to study the correlation between Asia monsoon and E1 Nino southern oscillation (ENSO).Various energy spectral densities are defined for waveiel transforms,analogous to those used in conventional Fourier analysis.Some comparisons are made by applying both wavelet and Fourier spectral methods (o the data.The wavelet analysis shows evidence of some relationship between Asia monsoon and ENSO,which the Fourier analysis resolves poorly.Correlation on several time scales,ranging from 2-4 years,11 years,and 22 years,become apparent with the wavelet cross-spectrum.Finally,the warelet cross-transform provides time localization of the distinctive features within the data record.Lonnie Hudgins 1996Advances in Atmospheric Sciences1996,13,3:21
2Femtosecond-laser sharp shaping of millimeter-scale geometries with vertical sidewalls显示文摘As femtosecond(fs)laser machining advances from micro/nanoscale to macroscale,approaches capable of machining macroscale geometries that sustain micro/nanoscale precisions are in great demand.In this research,an fs laser sharp shaping approach was developed to address two key challenges in macroscale machining(i.e.defects on edges and tapered sidewalls).The evolution of edge sharpness(edge transition width)and sidewall tapers were systematically investigated through which the dilemma of simultaneously achieving sharp edges and vertical sidewalls were addressed.Through decreasing the angle of incidence(AOI)from 0◦to−5◦,the edge transition width could be reduced to below 10µm but at the cost of increased sidewall tapers.Furthermore,by analyzing lateral and vertical ablation behaviors,a parameter-compensation strategy was developed by gradually decreasing the scanning diameters along depth and using optimal laser powers to produce non-tapered sidewalls.The fs laser ablation behaviors were precisely controlled and coordinated to optimize the parameter compensations in general manufacturing applications.The AOI control together with the parameter compensation provides a versatile solution to simultaneously achieve vertical sidewalls as well as sharp edges of entrances and exits for geometries of different shapes and dimensions.Both mm-scale diameters and depths were realized with dimensional precisions below 10µm and surface roughness below 1µm.This research establishes a novel strategy to finely control the fs laser machining process,enabling the fs laser applications in macroscale machining with micro/nanoscale precisions.Qiuchi Zhu Peixun Fan Nan Li Timothy Carlson Bai Cui Jean-François Silvain Jerry L Hudgins Yong Feng Lu 2021International Journal of Extreme Manufacturing2021,3,4:6
3Gastrointestinal sarcoidosis associated with pneumatosis cystoides intestinalis显示文摘A 39-year-old male reported fevers,weight loss,watery loose stools,and decreased visual acuity in his right eye over the prior five years.He was pancytopenic,had an elevated American council on exercise level,total bilirubin,and alkaline phosphatase.Computed tomography revealed massive hepatosplenomegaly and emphysematous lung changes.Liver biopsy showed non caseating granulomas.The patient was diagnosed with extrapulmonary sarcoidosis and was treated with prednisone.The patient symptomatically improved but 5 mo later presented with abdominal pain caused by perforation of the cecum.He underwent a cecectomy and pathology revealed pneumatosis cystoides intestinalis.This represents the first reported association between pneumatosis cystoides intestinalis and sarcoidosis.The etiology of pneumatosis cystoides intestinalis in this case was likely multifactorial and involved both effects of the corticosteroids as well as the advanced nature of the gastrointestinal sarcoidosis.Furthermore this case has the unique features of emphysematous lung changes and pancytopenia which are uncommon with sarcoidosis.Hussein Rahim Mubashir Khan Jay Hudgins Kevin Lee Lei Du Louis Amorosa 2013World Journal of Gastroenterology2013,19,7:3
