AIM To systematically search literature and determine a preferable surgical procedure in patients with failed conservative treatment of calcifying tendinitis of the *** The electronic online databases MEDLINE(through PubMed), EMBASE(through OVID), CINAHL(through EBSCO), Web of Science and Cochrane Central Register of Controlled Trials were systematically searched in May 2016. Eligible for inclusion were all available studies with level Ⅱ and level Ⅲ evidence(LoE). Data was assessed and extracted by two independent review authors using a specifically for this study designed data extraction *** Six studies(294 surgically treated shoulders) were included in this review. No significant differences between the three available treatment options(acromioplasty with the removal of the calcific deposits, acromioplasty or solely the removal of the calcific deposits) were detected regarding the functional and clinical outcome. The followup ranged from 12 mo to 5 years. Complication rates were low. No reoperations were necessary and the only reported complication was adhesive capsulitis, which in all cases could be treated conservatively with full recovery. CONCLuSION We found that all three available treatment options show good functional and clinical outcomes in the short and midterm. However, a favorable procedure is difficult to determine due to the lack of high-quality comparing studies.

Most of the important aspects of soliton propagation through optical fibers for transcontinental and transoceanic long distances can best be described using the nonlinear Schr?dinger *** solitons are electromagnetic waves that span in nonlinear dispersive media and permit the stress and intensity to stay unaltered as a result of the delicate balance between dispersion and nonlinearity ***,this study exploited the Jacobi elliptic method and obtained different soliton solutions of the decoupled nonlinear Schr?dinger equation with *** about the obtained solutions were made with the aid of some 3D graphs.

本文报道作者于１９９２～１９９３年在澳大利亚应用ＤＥＡＥＳｅｐｈａｄｅｘＡ－５０层析法对腺病毒群特异性抗原─—六面体壳蛋白（Ｈｅｘｏｎ）进行提取、纯化并免疫动物获得高效价的腺病毒群特异性抗体。在抗原洗脱过程中分别在０．０５Ｍ、０．２Ｍ和０．４８Ｍ出现了３个波峰。壳蛋白的洗脱浓度为０．４８Ｍ。为明确其生物学特性，作者应用ＳＤＳ－ＰＡＧＥ电泳。证实其分子量大约为４５ＫＤ。本文的实验结果为解决腺病毒的诊断抗体提供了新的简便、经济的方法。

In this paper, a three-parameter lifetime distribution named power Hamza distribution (PH) is proposed. The PH distribution is a useful generalization of the Hamza distribution which accommodates heavy-tailed, upside-down bathtub and J-shaped hazard rates making it more flexible than the Hamza distribution for modelling various kinds of lifetime data. A comprehensive account of the properties of this distribution is presented. The maximum likelihood estimators of the unknown model parameters are discussed. Finally, a real-life data is analyzed for illustrative purpose proving that the PH outperforms the Hamza distribution and several other lifetime distributions.

Recent advances in scanning transmission electron microscopy(STEM)have led to increased development of multidimensional STEM imaging modalities and novel image reconstruction *** interest arises because the main electron lens in a modern transmission electron microscope usually has a diffraction-space information limit that is significantly better than the real-space resolution of the same *** state-of-affairs is sometimes shared by other scattering methods in modern physics and contributes to a broader excitement surrounding multidimensional techniques that scan a probe while recording diffraction-space images,such as ptychography and scanning nano-beam ***,the contrasting resolution in the two spaces raises the question as to what is limiting their effective ***,we examine this paradox by considering the effects of aberrations in both image and diffraction planes,and likewise separate the contributions of pre-and post-sample *** consideration provides insight into aberration-measurement techniques and might also indicate improvements for super-resolution techniques.

We propose an efficient and low-power second harmonic generation(SHG)process in a silicon-compatible hybrid plasmonic microring *** making the microring resonator doubly resonant at the fundamental wavelength of 3.1μm and second harmonic wavelength of 1.55μm,the SHG efficiency is enhanced by almost two orders of magnitude when compared to the previous result induced in a straight plasmonic waveguide.A SHG efficiency of 13.71%is predicted for a low pump power of 20 mW in a ring with radius of 2.325μ*** device provides a potential route for realizing efficient frequency conversion between mid-infrared and near-infrared wavebands on a chip.

Objectives: The aim of this study was to evaluate the value of digital subtraction angiography (DSA) in thediagnostic evaluation of a highly selected patient population presenting with pulse-synchronous tinnitus(PST).Methods: We retrospectively reviewed the charts of all patients referred for evaluation of possiblevascular etiology of pulsatile tinnitus. Patients were evaluated with regards to presenting signs,comorbidities, non-invasive imaging results, angiographic findings and ***: Fifteen patients underwent cerebral DSA. Dural arteriovenous fistula (dAVF) was identified in sixpatients, and five patients had other significant vascular pathology identified on DSA. Seven patientswith ‘negative’ non-invasive imaging were found to have significant pathology on ***: Catheter angiography may have a significant yield in appropriately selected patients presenting with pulse synchronous tinnitus.
