| 1 | Diffusion weighted imaging in the liver显示文摘Diffusion weighted magnetic resonance imaging (DWI) is an imaging technique which provides tissue contrast by the measurement of diffusion properties of water molecules within tissues. Diffusion is expressed in an apparent diffusion coefficient (ADC), which reflects the diffusion properties unique to each type of tissue. DWI has been originally used in neuroradiology. More recently, DWI has increasingly been used in addition to conventional unenhanced and enhanced magnetic resonance imaging (MRI) in other parts of the body. The reason for this delay was a number of technical problems inherent to the technique, making DWI very sensitive to artifacts, which had to be overcome. With assessment of ADC values, DWI proved to be helpful in characterization of focal liver lesions. However, DWI should always be used in conjunction to conventional MRI since there is considerable overlap between ADC values of benign and malignant lesions. DWI is useful in the detection of hepatocellular carcinoma in the cirrhotic liver and detection of liver metastases in oncological patients. In addition, DWI is a promising tool in the prediction of tumor responsiveness to chemotherapy and the follow-up of oncological patients after treatment, as DWI may be capable of detecting recurrent disease earlier than conventional imaging.This review focuses on the most common applications of DWI in the liver. | Petra G Kele Eric J van der Jagt | 2010 | World Journal of Gastroenterology2010，16，13： | 48 |

| 3 | Adaptive optics based on machine learning: a review显示文摘Adaptive optics techniques have been developed over the past half century and routinely used in large ground-based telescopes for more than 30 years.Although this technique has already been used in various applications,the basic setup and methods have not changed over the past 40 years.In recent years,with the rapid development of artificial in-telligence,adaptive optics will be boosted dramatically.In this paper,the recent advances on almost all aspects of adapt-ive optics based on machine learning are summarized.The state-of-the-art performance of intelligent adaptive optics are reviewed.The potential advantages and deficiencies of intelligent adaptive optics are also discussed. | Youming Guo Libo Zhong Lei Min Jiaying Wang Yu Wu Kele Chen Kai Wei Changhui Rao | 2022 | Opto-Electronic Advances2022，5，7： | 6 |

| 5 | Artificial neural network models predicting the leaf area index:a case study in pure even-aged Crimean pine forests from Turkey显示文摘Background: Leaf Area Index(LAI) is an important parameter used in monitoring and modeling of forest ecosystems. The aim of this study was to evaluate performance of the artificial neural network(ANN) models to predict the LAI by comparing the regression analysis models as the classical method in these pure and even-aged Crimean pine forest stands.Methods: One hundred eight temporary sample plots were collected from Crimean pine forest stands to estimate stand parameters. Each sample plot was imaged with hemispherical photographs to detect the LAI. The partial correlation analysis was used to assess the relationships between the stand LAI values and stand parameters, and the multivariate linear regression analysis was used to predict the LAI from stand parameters. Different artificial neural network models comprising different number of neuron and transfer functions were trained and used to predict the LAI of forest stands.Results: The correlation coefficients between LAI and stand parameters(stand number of trees, basal area, the quadratic mean diameter, stand density and stand age) were significant at the level of 0.01. The stand age, number of trees, site index, and basal area were independent parameters in the most successful regression model predicted LAI values using stand parameters(/?;adj = 0.5431). As corresponding method to predict the interactions between the stand LAI values and stand parameters, the neural network architecture based on the RBF 4-19-1 with Gaussian activation function in hidden layer and the identity activation function in output layer performed better in predicting LAI(SSE(12.1040), MSE(0.1223), RM5 E(0.3497), AIC(0.1040), BIC(-777310) and R2(0.6392)) compared to the other studied techniques.Conclusion: The ANN outperformed the multivariate regression techniques in predicting LAI from stand parameters. The ANN models, developed in this study, may aid in making forest management planning in study forest stands. | ilker Ercanli Alkan Gunlu Muammer Senyurt Sedat Keles | 2018 | Forest Ecosystems2018，5，4： | 4 |

| 7 | Improvement in renal functions with transcatheter aortic valve implantation显示文摘BACKGROUND & OBJECTIVES:In recent years, emerging transcatheter aortic valve implantation (TAVI) has become an alternative for surgery。 However, with advanced age, several co-morbid factors together with contrast agent usage can cause deterioration in renal function and increase in the risk of acute kidney injury (AKI) with poor prognosis in patients with AKI。 Therefore, many patients cannot benefit from this treatment。 In this study, we aim to examine the effects of TAVI on renal functions。 METHODS AND RESULTS: Seventy patients, mean age of 77.6 years, underwent TAVI between July 2011 and December 2012。 Estimated glomerular filtration rate (eGFR) was calculated by using the Cockcroft and Gault Formula。 Patients were monitored for 48 h for urine output。 Stage 1 AKI, according to the VARC-2 AKIN system, developed in only five (7.1%) of the patients after the procedure。 There was a statistically significant increase between the mean 1(st) month eGFRs before (68。2 vs。 61.0, P < 0.01) and after (68。2 vs。 63.6, P < 0.05) the TAVI in the cohort。 After TAVI (48。5 mL/min, P < 0.01) and the 1(st) month (52.1 mL/min, P < 0.01), the eGFR of the 36 (51.4%) patients diagnosed with chronic kidney disease before the procedure showed a statistically significant increase in renal functions。 The hospital mortality rate was higher in the group which developed AKI (P < 0.01)。 First month eGFR showed a more statistically significant increase than pre-TAVI eGFR (62.8 and 69.8, P < 0.05, respectively) in AKI developing patients and this difference - though statistically not significant - continued into the sixth month。 CONCLUSIONS: In this study, we showed that the treatment of aortic stenosis through TAVI allows improvement of renal functions, and that AKI rates will be lower with careful patient selection, proper pre-procedural hydration, and careful use of contrast agent。 | Telat Keleş Huseyin Ayhan Durmaz Sarı Aslan AN Erdoğan KE Kasapkara Bilen Bayram Akçay Bozkurt | 2013 | Journal of Geriatric Cardiology2013，10，4： | 2 |
