New Zealand English has a history of more than 200 years. Compared with other English variants, New Zealand English vocabulary has formed its own unique linguistic characteristics in terms of Maori vocabulary, compound words, changes in lexical meaning, acronyms, slang, and idioms, etc. A study of the lexical features of New Zealand English is helpful to our comprehensive understanding of English as a universal language. With the development of economic and cultural exchanges between China and New Zealand, it is of great practical significance to the study of New Zealand English. 展开更多

Image blind deblurring uses an estimated blur kernel to obtain an optimal restored original image with sharp features from a degraded image with blur and noise artifacts.This method,however,functions on the premise that the kernel is estimated accurately,in this work,we propose an adaptive patch prior for improving the accuracy of kernel estimation.Our proposed prior is based on local patch statistics and can rebuild low-level features, such as edges,corners,and junctions,to guide edge and texture sharpening for blur estimation.Our prior is a nonparametric model,and its adaptive computation relies on internal patch information.Moreover,heuristic filters and external image knowledge are not used in our prior.Our method for the reconstruction of salient step edges in a blurry patch can reduce noise and over-sharpening artifacts.Experiments on two popular datasets and natural images demonstrate that the kernel estimation performance of our method is superior to that of other state-of-the-art methods. 展开更多

As one of most active gully types in the Chinese Loess Plateau,bank gullies generally indicate soil loss and land degradation.This study addressed the lack of detailed,large scale monitoring of bank gullies and proposed a semi-automatic method for extracting bank gullies,given typical topographic features based on 5 m resolution DEMs.First,channel networks,including bank gullies,are extracted through an iterative channel bum-in algorithm.Second,gully heads are correctly positioned based on the spatial relationship between gully heads and their corresponding gully shoulder lines.Third,bank gullies are distinguished from other gullies using the newly proposed topographic measurement of "relative gully depth (RGD)."The experimental results from the loess hilly area of the Linjiajian watershed in the Chinese Loess Plateau show that the producer accuracy reaches 87.5%. The accuracy is affected by the DEM resolution and RGD parameters,as well as the accuracy of the gully shoulder line.The application in the Madigou watershed with a high DEM resolution validated the duplicability of this method in other areas.The overall performance shows that bank gullies can be extracted with acceptable accuracy over a large area,which provides essential information for research on soil erosion,geomorphology,and environmental ecology. 展开更多

Since X-linked chronic granulomatosis disease(X-CGD)exhibits no specific clinical symptoms at an early stage,early diagnosis is difficult and depends predominantly on neonatal screening.Therefore,the aim of this study was to explore routine biomarkers for X-CGD in children and provide clues for early diagnosis.The cases of 10 children with X-CGD diagnosed at Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology from 2013 to 2016 and 122 Chinese children with X-CGD reported in the literature were summarized.Serum biomarkers and clinical symptoms at acute infection were organized.A total of 132 children with X-CGD were enrolled in this study.For 55.8%of the patients,the diagnosis was delayed more than one year after the onset of the first symptoms because no typical clinical symptoms manifested.Children with X-CGD at an acute infection stage showed three recurrent signs in temis of serum biomarkers:(1)the total number of white blood cells(especially N%)was in creased significantly,accompanied by anemia in some cases;(2)C-reactive protein(CRP)levels were increased significantly;and(3)most of the patients exhibited very high serum IgG levels(>12 g/L).Diagnosis of X-CGD at an early age is difficult because of its nonspecific clinical features.Our study suggested children with X-CGD suffering acute infection show increases in three typical serum biomarkers,which can provide clues for early diagnosis. 展开更多

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, which in turns accounts for the sixth most common cancer worldwide. Despite being the 6th most common cancer it is the second leading cause of cancer related deaths. HCC typically arises in the background of cirrhosis, however, about 20% of cases can develop in a non-cirrhotic liver. This particular subgroup of HCC generally presents at an advanced stage as surveillance is not performed in a non-cirrhotic liver. HCC in non-cirrhotic patients is clinically silent in its early stages because of lack of symptoms and surveillance imaging; and higher hepatic reserve in this population. Interestingly, F3 fibrosis in non-alcoholic fatty liver disease, hepatitis B virus and hepatitis C virus infections are associated with high risk of developing HCC. Even though considerable progress has been made in the management of this entity, there is a dire need for implementation of surveillance strategies in the patient population at risk, to decrease the disease burden at presentation and improve the prognosis of these patients. This comprehensive review details the epidemiology, risk factors, clinical features, diagnosis and management of HCC in non-cirrhotic patients and provides future directions for research. 展开更多

Lung medical image retrieval based on content similarity plays an important role in computer-aided diagnosis of lung cancer.In recent years,binary hashing has become a hot topic in this field due to its compressed storage and fast query speed.Traditional hashing methods often rely on high-dimensional features based hand-crafted methods,which might not be optimally compatible with lung nodule images.Also,different hashing bits contribute to the image retrieval differently,and therefore treating the hashing bits equally affects the retrieval accuracy.Hence,an image retrieval method of lung nodule images is proposed with the basis on convolutional neural networks and hashing.First,a pre-trained and fine-tuned convolutional neural network is employed to learn multilevel semantic features of the lung nodules.Principal components analysis is utilized to remove redundant information and preserve informative semantic features of the lung nodules.Second,the proposed method relies on nine sign labels of lung nodules for the training set,and the semantic feature is combined to construct hashing functions.Finally,returned lung nodule images can be easily ranked with the query-adaptive search method based on weighted Hamming distance.Extensive experiments and evaluations on the dataset demonstrate that the proposed method can significantly improve the expression ability of lung nodule images,which further validates the effectiveness of the proposed method. 展开更多
