We present 2 cases of hepatocyte nuclear factor 1α (HNF1α)-mutated adenomatosis, discovered for reasons unrelated to this disease, and identified using immunohistochemical methods. These new tools may further our understanding of the link between adenomas/adenomatosis subtypes and their complications, and their association with other abnormalities.

Modulational Instability in a Pair of Non-identical Coupled Nonlinear Electrical Transmission Lines

引用

Communications in Theoretical Physics 2013年第7期60卷 93-100页

In this work, we investigate the dynamics of modulated waves non-identical coupled nonlinear transmission lines. Traditional methods for avoiding mode mixing in identical coupled nonlinear electrical lines consist of adding the same number of linear inductors in each branch. Adding linear inductors in a single line leads to asymmetric coupled nonlinear electrical transmission lines which propagate the signal and the mode mixing. On one hand, the difference between the two lines induced the fission for only one mode of propagation. This fission is influenced by the amplitude of the signal and the amount of the input energy as well; it also narrows the width of the input pulse soliton, leading to a possible increasing of the bit rate. On the other hand, the dissymmetry of the two lines converts the network into a good amplifier for the ω_ mode which corresponds to the regime admitting low frequencies.

Calculation of CO_2, CH_4 and H_2S Solubilities in Aqueous Electrolyte Solution at High Pressure and High Temperature

引用

Journal of Thermal Science 1997年第4期6卷 251-259页

作者： Carrier hervé Suyu Ye Lagourette Bernard Alliez Jacques Xans Pierre Laboratoire Haute Pression Centre Universitaire de Recherche Scientifique Université de Pau Pau France

This paper reports an investigation into the characterisation of liquidaivapor electrolyte solutions at high pressure and high temperature. A procedure to enable calcuIations of methane, carbon dioxide and hydrogen sulphide solubilities in brines (0-6 m.) for temperature from 25 to 350℃ and for pressures from 1 to 1800 bar is presented. The model is based on Helgeson, Kirkham and Flowers modified equations of state (HKF) and on the semi-empirical interaction model introduced by Pitzer. HKF modified equations of state are used to calculate the reference fugacity of gas species, and the Pitzer ionic interaction model is used to calculate the activity coefficient of dissolved species (i.e. ionic or neutral).The efficiency of the combination of the two models is confirmed by several comparisons with data in the literature.

Endoscopic management of an esophagopericardial fistula after radiofrequency ablation for atrial fibrillation

引用

World Journal of Gastroenterology 2013年第21期19卷 3352-3353页

作者： Lucille Quénéhervé Nicolas Musquer Franck Léauté Emmanuel Coron Digestive Diseases Institute University Hospital of Nantes44035 NantesFrance Department of Radiology University Hospital of Nantes44035 NantesFrance

A case is reported of a 76-year-old man with a past history of atrial fibrillation. A radiofrequency ablation procedure was suggested following several failed cardioversion attempts. However, an esophagopericardial fistula complicated the procedure. This life-threatening complication was successfully managed using both the placement of a covered esophageal stent and surgical pericardial and mediastinal drainage. In fact, no persisting fistula could be detected when the esophageal stent was removed seven weeks later. Atrioesophageal and esophagopericardial fistulas are two of the most severe complications associated with cardiological radiofrequency ablation procedures. They are responsible for majority of the deaths associated with this procedure. Despite the extremely high morbimortality associated with cardiothoracic surgery in such conditions, this treatment is the gold-standard for the management of such complications. This case report emphasizes the importance and efficacy of the endoscopic approach as part of a multidisciplinary management approach to this serious adverse event following radiofrequency ablation for atrial fibrillation.

Even though a large number of large-scale arch dams with height larger than 200 m have been built in the world, the transient groundwater flow behaviors and the seepage control effects in the dam foundations under difficult geological conditions are rarely reported. This paper presents a case study on the transient groundwater flow behaviors in the rock foundation of Jinping I double-curvature arch dam, the world＇s highest dam of this type to date that has been completed. Taking into account the geological settings at the site, an inverse modeling technique utilizing the time series measurements of both hydraulic head and discharge was adopted to back-calculate the permeability of the foundation rocks,which effectively improves the uniqueness and reliability of the inverse modeling results. The transient seepage flow in the dam foundation during the reservoir impounding was then modeled with a parabolic variational inequality（PVI） method. The distribution of pore water pressure, the amount of leakage, and the performance of the seepage control system in the dam foundation during the entire impounding process were finally illustrated with the numerical results.
