World Journal of Gastroenterology 2009年第41期15卷 5232-5235页

Spontaneous or traumatic intramural bleeding of the esophagus, which is often associated with overlying mucosal dissection, constitutes a rare spectrum of esophageal injury called dissecting intramural hematoma of the esophagus (DIHE). Chest pain, swallowing diffi culty, and minor hematemesis are common, which resolve spontaneously in most cases. This case report describes a patient with spontaneous DIHE with recurrent massive bleeding which required critical management and highlights a potential role for therapeutic angiography as an alternative to surgery.

Detection of chemicals in water using a three-dimensional graphene porous structure as liquid-vapor separation filter

引用

Nano Research 2017年第3期10卷 971-979页

作者： Taekyung Lim jaejun Lee Jonghun Lee Sanghyun Ju Department of Physics Kyonggi University Suwon Gyeonggi-Do 443-760 Republic of Korea

In this study, we report the utilization of a three-dimensional （3D） porous graphene structure as liquid-vapor separation filter, which allows the passage of chemical vapors while blocking liquid chemicals and water. The blockage of liquid chemicals and water from semiconducting sensing regions is required to avoid abnormal transistor characteristics. In order to impart omniphobic characteristics, a （heptadecafluoro-1,1,2,2-tetrahydrodecyl）trichlorosilane （HDF-S） self-assembled monolayer was coated on the surface of the 3D porous graphene structure. The concentration of chemical agents in water could be consistently detected by observing the shift in the threshold voltage in the oxide nanowire transistor covered by the HDF-S self-assembled 3D graphene structure. The proposed monitoring method is expected to offer means for application in different environments by providing a stable sensing performance.

Iterative learning-based many-objective history matching using deep neural network with stacked autoencoder

This paper presents an innovative data-integration that uses an iterative-learning method,a deep neural network(DNN)coupled with a stacked autoencoder(SAE)to solve issues encountered with many-objective history *** proposed method consists of a DNN-based inverse model with SAE-encoded static data and iterative updates of supervised-learning data are based on distance-based clustering *** functions as an inverse model and results in encoded flattened data,while SAE,as a pre-trained neural network,successfully reduces dimensionality and reliably reconstructs *** iterative-learning method can improve the training data for DNN by showing the error reduction achieved with each iteration *** proposed workflow shows the small mean absolute percentage error below 4%for all objective functions,while a typical multi-objective evolutionary algorithm fails to significantly reduce the initial population *** learning-based manyobjective history matching estimates the trends in water cuts that are not reliably included in dynamicdata *** confirms the proposed workflow constructs more plausible *** workflow would be a reliable alternative to overcome the less-convergent Pareto-based multi-objective evolutionary algorithm in the presence of geological uncertainty and varying objective functions.

对韩国汉语学习者来说,因果连词“所以”是他们常犯的典型的语篇衔接错误。然而,导致这些错误的原因却极少受到关注。相关研究者从母语迁移的角度,似乎解释了导致这种错误的原因。本文通过写作实验,从语言迁移、过度归纳、教法和教材等不同角度,深度分析“所以”的使用模式及其被高频使用的原因。
