Oily wastewater and oil spills pose a threat to the environment and human health, and absorbing these harmful organics through porous aerogel materials is an efficient method for oil/water separation.

For the management of wind energy, wind speed forecasting is often required. Accurate multi-step ahead wind speed forecasts make the power system be adjusted timely and properly to ensure the stable and efficient operation of power system. Currently, various techniques have been developed for multi-step ahead wind speed forecasting. However, the correlation among different forecasting steps is often neglected in current multi-step ahead wind speed forecasting approaches, and the characteristic of heteroscedasticity in wind speed forecasting errors is usually not taken into consideration. In this work, a novel multi-step ahead forecasting method based on multi-kernel learning is developed. This method considers the task correlation, which represented by the covariance of multi-step ahead forecasting tasks, as well as the heteroscedasticity of forecasting errors. The optimization is solved within the framework of variational Bayesian. Thus, a correlation aware multi-step ahead wind speed forecasting technique with heteroscedastic multi-kernel learning is designed. In this paper, the experimental results in different wind farms and different seasons prove that the regression model considering the characteristics of multi-step ahead wind speed forecasting, task correlation and heteroscedasticity, will produce more accurate forecasts than the other models as for two to six-ahead wind speed forecasting. However, it is difficult to tell which characteristic is more important from the forecasting results. So, the regression model considering both of them will be more reasonable. Moreover, the training time of the proposed model is more than 10 min but less than 20 min. Thus, two to six-step ahead wind speed forecasts can be used in some practical applications, such as the load dispatch planning and the load increment/decrement decisions.

This study focused on identifying bladder cancer (BC)-associated genes, transcription factors (TFs), and microRNAs (miRNAs). Two microarray data sets GSE37815 and GSE40355 were utilized to screen common differentially expressed genes (DEGs) associated with BC. Then, functional enrichment analysis was performed for elucidating the involved functions of DEGs. Subsequently, the protein-protein interaction (PPI) network and submodule of PPI network were analyzed. Finally, the regulation relationships of TF-DEGs and miRNA-DEGs were obtained to construct miRNA-target-TF regulatory network. DEGs were identified across BC and normal bladder tissues samples. Functional enrichment analysis results showed that most upregulated DEGs were closely associated with the Gene Ontology function of "mitotic spindle assembly checkpoint" and pathway of "Cell cycle," whereas most downregulated DEGs were significantly associated with "Complement and coagulation cascades" pathway (e.g., A2M and F13A1) and "Ras signaling pathway" (e.g., GNG11). DEGs such as F13A1 and A2M were highlighted in the PPI network and Submodule 1. In addition, three centromere-associated CENPK, CENPF, and CENPO were enriched in Submodule 2. Moreover, miR-519d had high degree in the regulatory network and CENPO was predicted to be one target of miR-519d. The upregulated CENPK, CENPF, and CENPO, and downregulated A2M, F13A1, and GNG11 might contribute to the progression of BC. In addition, the downregulated miR-519d might lead to the development of BC by upregulating the expression of CENPO. However, future investigation of those findings should be needed.

Plexiform angiomyxoid myofibroblastic tumor (PAMT) is a rare gastric mesenchymal entity with a peculiar plexiform pattern, bland spindle cells and myxoid stroma rich in arborizing blood vessels. Here we report a 44-year-old Chinese woman with PAMT. Initially she was admitted for removal of a gastric antral‘polyp’ found on a routine examination 5 months previously. Our gastroscopy showed a 0.8 × 0.8 cm polyp-like mass in the antrum which protruded into the lumen. Endoscopic submucosal dissection (ESD) was performed to remove this mass en bloc. The specimen was carefully examined by pathologists, and the correct diagnosis of PAMT was finally made. The tumor in this case depicted typical histopathological and immunohistochemical features of gastric PAMT. This PAMT was not only the smallest on endoscopic examination in the literature but also—unlike the already reported PAMTs—exhibited a focal hyperechogenic lesion on endoscopic ultrasonography (EUS). This information highlights its value on how to identify a PAMT at its early stage.

Wind energy is regarded as a worldwide renewable and alternative energy that can relieve the energy shortage, reduce environmental pollution, and provide a significant potential economic benefit. In this paper, a hybrid method is developed to properly and efficiently forecast the daily wind speed in Hainan Province, China. The proposed hybrid forecasting model consists of outlier detection and a bivariate fuzzy time series, which provides a more powerful forecasting capacity of daily wind speed than that of traditional single forecasting models. To verify the developed approach, daily wind speed data from January 2008 to December 2012 in Hainan Province, China, are used for model construction and testing. The results show that the developed hybrid forecasting model achieves high forecasting accuracy and is suitable for forecasting the wind energy of China's large wind farms.

To explore the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) combined with Surepath liquid-based cytology test for lung and mediastinal lymphadenopathy.Eighty EBUS-TBNA cases in West China Hospital of Sichuan University collected from December 2011 to June 2014 were retrospectively analyzed. The conventional smears and Surepath liquid based preparations were reviewed and compared with histological biopsy. Evaluated whether liquid based preparation could improve the satisfactory rate and diagnostic accuracy.This study included 53 men and 27 women, the male to female ratio was 1.96:1.00; the age ranged from 17 to 79 (mean 54) years. One to four lymph node groups were aspirated in each patient, resulting in a total of 109 lymph node groups, including 57 paratracheal, 34 subcarinal, three tracheal bronchial, seven pulmonary and four hilar lymph node groups. The definite locations of four other mediastinal lymph node groups were not known. The overall satisfactory rate of conventional smears and liquid-based cytology test was 90.0% and 92.5%, respectively. By histology, there were 37 cases diagnosed as malignant tumors, nine as tuberculosis, two as sarcoidosis, 11 as unexplained granulomatous inflammation, and 27 as other benign lesions. The sensitivity, specificity and accuracy of conventional cytological smears for tumors were 86.5%, 97.7% and 92.5% respectively; the positive and negative predictive values were 97.0% and 89.4% respectively. The sensitivity, specificity and accuracy of the liquid-based preparation were 89.2%, 97.7% and 93.8% respectively; the positive and negative predictive values were 97.1% and 91.3% respectively. Combining the conventional cytological smears and liquid based preparation, the sensitivity, specificity and accuracy were 91.9%, 97.7% and 95.0% respectively; and the positive and negative predictive values were 97.1% and 93.3% respectively.EBUS-TBNA is a good method to diagnose lung and mediastinal lymphadenopathy. Surepath liquid based cytology test could improve the sample satisfactory rate, the diagnostic sensitivity and accuracy. If combined with immunocytochemistry it could be useful for further tumor typing. EBUS-TBNA combined with Surepath liquid based preparation is an effective complement for the histologic biopsy.

Bilateral mandibular Garrè's osteomyelitis is rare. In this article, a case of Garrè's osteomyelitis with bilateral mandible is reported. Its etiology, clinical pathologic features, diagnosis, differential diagnosis, and treatment methods are discussed by reviewing relevant literature.

Paraganglioma, also termed extra-adrenal pheochromocytoma, may be observed at the base of the skull and neck as well as within the mediastinum and periaortic region. The clinical symptoms of paraganglioma of the urinary bladder include intermittent hypertensive attacks, micturition, headaches and palpitations due to high catecholamine levels; these types of paragangliomas are extremely rare. However, certain bladder paragangliomas do not present with any of these symptoms; thus, surgeons are not pre-warned on how to prepare for their resection. Surgery to remove pheochromocytomas may therefore result in an intraoperative hypertensive crisis and increase the mortality rate. This infrequent type of paraganglioma is only recognized through histological examination following surgery. The current study reports the case of a 61-year-old male with urinary bladder paraganglioma. The patient presented with hypertension, which was controlled to within a normal range using diovan and norvasc treatment; in addition, the patient's blood pressure was not altered with urination or postural changes. The patient was not administered an α-blocking agent or a blood volume expander prior to the surgery, and during the partial cystectomy no hypertensive crisis occurred.

Idiopathic distal anterior choroidal artery (AChoA) aneurysms are particularly rare. Their diagnosis and treatment are difficult because of the particular characteristic of pathological anatomy. Our case mainly presented with intraventricular hemorrhage. His idiopathic aneurysm was located in the trigone of the undilated ventricle. Computed tomographic angiography demonstrated both the precise aneurysm and parent artery even when there was no dilated parent artery for the first time. It is also the first time this tiny aneurysm was resected assisted by frameless stereotactic guidance during operation after absorption of intraventricular blood. Computed tomographic angiography and frameless stereotactic guidance benefit the diagnosis and treatment of this kind of aneurysm. Sacrificing plexual AChoA did not cause any neurologic deficit.
