| 1 | 土-混凝土接触面特性环剪单剪试验比较研究显示文摘对可用于接触面应力变形及强度特性试验的直剪仪、单剪仪及环剪仪的优缺点进行了比较分析。对某土料与混凝土接触面的应力-变形及强度特性进行了单剪试验研究,试验包括土-混凝土接触面及土-泥皮-混凝土接触面两种。同时,将已有的环剪试验成果与单剪试验结果进行了比较分析。研究了环剪试验与单剪试验成果的差异。结果表明,单剪试验测得的抗剪强度比环剪试验测得的低30%~40%,环剪试验用于接触面强度特性研究较合适,而单剪试验用于较低应力水平下的应力-变形试验更好,泥皮的存在使得接触面强度降低30%左右。 | 朱俊高 | 2011 | 岩土力学2011,32,3: | 33 |
| 2 | Geometric Mean Decomposition Based Hybrid Precoding for Millimeter-Wave Massive MIMO显示文摘Hybrid precoding can reduce the number of required radio frequency(RF)chains in millimeter-Wave(mmWave) massive MIMO systems. However, existing hybrid precoding based on singular value decomposition(SVD) requires the complicated bit allocation to match the different signal-to-noise-ratios(SNRs) of different sub-channels. In this paper,we propose a geometric mean decomposition(GMD)-based hybrid precoding to avoid the complicated bit allocation. Specifically,we seek a pair of analog and digital precoders sufficiently close to the unconstrained fully digital GMD precoder. To achieve this, we fix the analog precoder to design the digital precoder, and vice versa. The analog precoder is designed based on the orthogonal matching pursuit(OMP) algorithm, while GMD is used to obtain the digital precoder. Simulations show that the proposed GMD-based hybrid precoding achieves better performance than the conventional SVD-based hybrid precoding with only a slight increase in complexity. | Tian Xie Linglong Dai Xinyu Gao Muhammad Zeeshan Shakir Jianjun Li | 2018 | China Communications2018,15,5: | 17 |

| 6 | High body mass index predicts multiple prostate cancer lymph node metastases after radical prostatectomy and extended pelvic lymph node dissection显示文摘Our aim is to evaluate the association between body mass index(BMI)and preoperative total testosterone(TT)levels with the risk of single and multiple metastatic lymph node invasion(LNI)in prostate cancer patients undergoing radical prostatectomy and extended pelvic lymph node dissection.Preoperative BMI,basal levels of TT,and prostate-specific antigen(PSA)were evaluated in 361 consecutive patients undergoing radical prostatectomy with extended pelvic lymph node dissection between 2014 and 2017・Patients were grouped into either nonmetastatic,one,or more than one metastatic lymph node invasion groups.The association among clinical factors and LNI was evaluated.LNI was detected in 52(14.4%)patients:28(7.8%)cases had one metastatic node and 24(6.6%)had more than one metastatic node.In the overall study population,BMI correlated inversely with TT(r=-0.256;P<0.0001).In patients without metastases,BMI inversely correlated with TT(r=-0.282;P<0.0001).In patients with metastasis,this correlation was lost.In the overall study population,BMI(odds ratio[OR]=1.268;P=0.005)was the only in dependent clinical factor associated with the risk of multiple metastatic LNI compared to cases with one metastatic node.In the nonmetastatic group,TT was lower in patients with BMI>28 kg m^2(P<0.0001).In patients with any LNI,this association was lost(P=0.232).The median number of positive nodes was higher in patients with BMI>28 kg m^2(P-0.048).In our study,overweight and obese patients had a higher risk of harboring multiple prostate cancer lymph node metastases and lower TT levels when compared to patients with normal BMI. | Antonio B Porcaro Alessandro Tafuri Marco Sebben Tania Processali Marco Pirozzi Nelia Amigoni Riccardo Rizzetto Aliasger Shakir Maria Angela Cerruto Matteo Brunelli Salvatore Siracusano Walter Artibani | 2020 | Asian Journal of Andrology2020,22,3: | 3 |
