| 1 | The influence of microwave irradiation on rocks for microwaveassisted underground excavation显示文摘Demand is growing for explosive-free rock breakage systems for civil and mining engineering, and spaceindustry applications. This paper highlights the work being undertaken in the Geomechanics Laboratoryof McGill University to make a real application of microwave-assisted mechanical rock breakage to fullfacetunneling machines and drilling. Comprehensive laboratory tests investigated the effect of microwaveradiation on temperature profiles and strength reduction in hard rocks (norite, granite, and basalt)for a range of exposure times and microwave power levels. The heating rate on the surface of the rockspecimens linearly decreased with distance between the sample and the microwave antenna, regardlessof microwave power level and exposure time. Tensile and uniaxial compressive strengths were reducedwith increasing exposure time and power level. Scanning electron micrographs (SEMs) highlightedfracture development in treated basalt. It was concluded that the microwave power level has a strongpositive influence on the amount of heat damage induced to the rock surface. Numerical simulations ofelectric field intensity and wave propagation conducted with COMSOL Multiphysics software generatedtemperature profiles that were in close agreement with experimental results. | Ferri Hassani Pejman M.Nekoovaght Nima Gharib | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，1： | 69 |
| 2 | Need for a comprehensive medical approach to the neuroimmuno-gastroenterology of irritable bowel syndrome显示文摘Irritable bowel syndrome (IBS) is defined by the Rome Ⅲ criteria as symptoms of recurrent abdominal pain or discomfort with the onset of a marked change in bowel habits with no evidence of an inflammatory,anatomic,metabolic,or neoplastic process.As such,many clinicians regard IBS as a central nervous system problem of altered pain perception.Here,we review the recent literature and discuss the evidence that supports an organic based model,which views IBS as a complex,heterogeneous,inter-dependent,and multi-variable inflammatory process along the neuronal-gut axis.We delineate the organic pathophysiology of IBS,demonstrate the role of inflammation in IBS,review the possible differences between adult and pediatric IBS,discuss the merits of a comprehensive treatment model as taught by the Institute of Functional Medicine,and describe the potential for future research for this syndrome. | Pejman Katiraei Gilberto Bultron | 2011 | World Journal of Gastroenterology2011，17，23： | 13 |
| 3 | Relationship between serum ferritin and hemoglobin levels determined by cardiac and hepatic T2 MRI in beta-thalassemia intermedia and major patients显示文摘背景 Thalassemia 专业是最普通的世袭混乱之一,并且它通过血红素合成平衡的扰乱在身体引起无效造血作用。在在这些病人的身体的铁超载的常规输血原因复杂并发症。织物铁地位能被测量浆液和肝活体检视 ferritin 层次并且由 T2 决定 * MRI。这研究由 T2 估计了在浆液 ferritin 和血红素之间的关系 * 心和肝的 MRI。这代表性的描述的研究与在 Shafa 医院为 Thalassemia 和 Hemoglobinopathies 访问了中心的 beta-thalassemia intermedia 和专业在病人上被执行的方法,阿瓦十,在 2014 和 2015 之间。所有病人每 24 个星期正在收到常规输血。皮尔森关联测试被用来估计浆液 ferritin 和 T2 * 从心和肝 MRI 的价值。260 个病人全部的结果 A (吝啬的年龄是 23 岁的) 在学习被注册。在肝和心的铁超载的发生分别地是 83% 和 39% 。浆液 ferritin 层次与 T2 显示出很强壮的反的关联 * 心上的价值(r =-3.54, p < 0.0001 ) 并且肝(r =-3.03, p < 0.0001 ) MRI。另外,一个有意义的相互作用在 T2 之间被观察 * 从肝和心 MRI 的价值(r = 0.29, p < 0.0001 ) 。结论浆液 ferritin 强烈并且相反地与 T2 被相关 * 在有 thalassemia 的病人的肝和心的 MRI 的价值。因此, T2 * MRI 能被用来与很高的精确性估计织物铁层次。 | Bijan Keikhaei Pejman Slehi-fard Seyed-Ali Nojottmi Abbas Khosravi | 2017 | Frontiers in Biology2017，12，4： | 2 |
| 4 | Evaluating single-channel speech separation performance in transform-domain显示文摘Single-channel separation (SCS) is a challenging scenario where the objective is to segregate speaker signals from their mixture with high accuracy. In this research a novel framework called subband perceptually weighted transformation (SPWT) is developed to offer a perceptually relevant feature to replace the commonly used magnitude of the short-time Fourier transform (STFT). The main objectives of the proposed SPWT are to lower the spectral distortion (SD) and to improve the ideal separation quality. The performance of the SPWT is compared to those obtained using mixmax and Wiener filter methods. A comprehensive statistical analysis is conducted to compare the SPWT quantization performance as well as the ideal separation quality with other features of log-spectrum and magnitude spectrum. Our evaluations show that the SPWT provides lower SD values and a more compact distribution of SD,leading to more acceptable subjective separation quality as evaluated using the mean opinion score. | Pejman MOWLAEE Abolghasem SAYADIYAN Hamid SHEIKHZADEH | 2010 | Journal of Zhejiang University-Science C(Computers and Electronics)2010，11，3： | 1 |
