Degenerate black rings in D=5 minimal supergravity

We consider both gauged and ungauged minimal supergravities in five dimensions and analyse the charged rotating solutions with two equal angular momenta *** the electric charge Q∼j^(2/3) with some specific coefficient,we find new extremal black objects emerge that are asymptotic to either Minkowski or global AdS spacetimes and can be best described as degenerate black *** near-horizon geometry is locally AdS3×S^(2),where the periodic U(1)fibre coordinate in S 3 untwists and collapses to be the degenerate part of the AdS3 *** turns out that there are two branches of extremal rotating black holes,starting as the extremal RN black holes of the same mass,but opposite *** the increasing of the angular momentum,they will join to become the same degenerate black ring,where the Gibbs free energies however are not continuous at the *** the same Q(j)relation,we find that there is in addition a rotating soliton whose mass is smaller than that of the degenerate black ring.

Management and outcome of hepatocellular adenoma with massive bleeding at presentation

引用

World journal of Gastroenterology 2017年第25期23卷 4579-4586页

作者： Anne j Klompenhouwer Robert A de Man Maarten Gj Thomeer jan NM Ijzermans Department of Surgery Department of Gastroenterology and Hepatology Department of Radiology

To evaluate outcome of acute management and risk of rebleeding in patients with massive hemorrhage due to hepatocellular adenoma (HCA). METHODSThis retrospective cohort study included all consecutive patients who presented to our hospital with massive hemorrhage (grade II or III) due to ruptured HCA and were admitted for observation and/or intervention between 1999-2016. The diagnosis of HCA was based on radiological findings from contrast-enhanced magnetic resonance imaging (MRI) or pathological findings from biopsy or resection of the HCA. Hemorrhage was diagnosed based on findings from computed tomography or MRI. Medical records were reviewed for demographic features, clinical presentation, tumor features, initial and subsequent management, short- and long-term complications and patient and lesion follow-up. RESUlTSAll patients were female (n = 23). Treatment in the acute phase consisted of embolization (n = 9, 39.1%), conservative therapy (n = 13, 56.5%), and other intervention (n = 1, 4.3%). Median hemoglobin level decreased significantly more on days 0-3 in the intervention group than in the patients initially treated conservatively (0.9 mmol/l vs 2.4 mmol/l respectively, P = 0.006). In total, 4 patients suffered severe short-term complications, which included hypovolemic shock, acute liver failure and abscess formation. After a median follow-up of 36 mo, tumor regression in non-surgically treated patients occurred with a median reduction of 76 mm down to 25 mm. Four patients underwent secondary (elective) treatment (i.e., tumor resection) to address HCA size of > 5 cm and/or desire for future pregnancy. One case of rebleeding was documented (4.3%). None of the patients experienced long-term complication (mean follow-up time: 36 mo). CONClUSIONWith a 4.3% risk of rebleeding, secondary (elective) treatment of HCA after massive hemorrhage may only be considered in patients with persistent HCA > 5 cm.

The purpose of this paper is to present an application of the rock engineering system(RES) methodology in hazard assessment of rockfalls occurred along a 430 km long section of the Chengdu-lhasa *** within the suture zone created by the collision of the Indian and Eurasian tectonic plates,rockfall hazard analysis is complicated by extensive distribution of dangerous blocks and boulders,lack of field data,complex geological structure,difficult site conditions and the high number of interactive factors.A comprehensive approach is developed for evaluating rockfall hazards in the complex environments,which allows the utilization of all the knowledge about intensity,frequency and hazards of *** on the objective of rockfall hazard assessment,factors relevant to rockfall intensity are selected to be block geometry,block strength,slope geometry,slope materials. vegetation,motion modes,coefficient of restitution,resistance coefficient,possible velocity and maximum travel distance of rockfalls,and factors affecting rockfall frequency are reduced to number of blocks,block stability,triggering events of rockfalls,and rockfall history. To evaluate interactions of parameters influencing rockfall intensity or rockfall frequency,two interaction matrices are established by placing the chosen parameters in the leading diagonal of a square matrix and considering parameter interactions in the offdiagonal boxes of the *** weighting,classification and rating of those parameters,the rockfall intensity index RⅡand rockfall frequency index RFI for 19 slopes are computed,and the rockfall hazard index RHI obtained by the product of RII and RFI(see Fig.I).Then the rockfall hazards of the 19 slopes are classified and ordered in terms of the magnitudes of RHI,which provides a scientific basis for optimization of mitigation costs. This application indicates that the RES methodology can be used to analyze the interaction mechanism of numerous parameters sensitive

头皮上约有10万个毛囊不断将预先形成的皮脂转运至头皮表面,使日均分泌的皮脂总量维持在"克"的水平。先前的研究发现,与邻近的前额部皮肤相比,头皮的皮脂分泌率要低得多。尽管这两处皮脂的日常水平(SCl,皮脂分泌平衡状态,单位μg/cm^2)相似,但其动力学有着很大差异:前额在清洁后3 h达到SCl,而头皮则需要2~3 d。
