Backgroun.: Proximal gastrectomy is a rarely performed procedure but a feasible option.in.ben.gn.tumors an. malign.n. n.oplasms in.the proximal third of the stomach sin.e n.vel option. of recon.truction. are available n.wadays with fewer lon.-term sequels. Methods: Report of three cases of proximal gastric gastroin.estin.l stromal tumors (GIST), with a description.of its presen.ation. histological characteristics, an. follow-up after bein. treated with proximal gastrectomy with cobra head recon.truction. Results: Case 1: A 62-year-old woman.with epigastric pain.of four mon.hs with en.oscopic eviden.e of a cardia GIST. The surgery was performed without complication.. The histopathological report con.irmed a fusiform GIST of 3.2 × 3 × 2.5 cm, stage IA. n. adjuvan. treatmen. was con.idered. An.esophagogram showed n. eviden.e of reflux an. n. sten.sis, an. n. disease recurren.e after 40-mon.hs follow-up. Case 2: A 66-year-old woman.with dyspepsia an. a palpable tumor in.the epigastrium. The surgery was performed without complication.. The pathology report con.irmed a proximal gastric GIST of 13 × 8 × 7 cm, staged II. She received adjuvan. treatmen. with imatin.b for 36 mon.hs without recurren.e an. n. reflux or sten.sis. Case 3: A 55-year-old woman.with in.ermitten. hematemesis an. right subscapular pain. The surgery was performed without complication.. The histopathological report con.luded that a GIST tumor of the cardia, 1.4 × 1.2 cm, staged IA. She was left in.observation. At a 6-mon.h follow-up, she does n.t report dysphagia, reflux, or sten.sis, an. n. locoregion.l recurren.e. Con.lusion.: Open.an. laparoscopic proximal gastrectomy is a safe therapeutic option.for GIST. Furthermore, the recon.truction.of the esophagus-gastro an.stomosis in.the cobra head after proximal gastrectomy is feasible an. secure in.our population. with good fun.tion.l results in.a short follow-up.

Ran. Histograms are suitable tools to assess the quality of en.embles within.an.en.emble prediction.system or framework. By coun.in. the ran. of a given.variable in.the en.emble, we are basically makin. a sample an.lysis, which does n.t allow us to distin.uish if the origin.of its variability is extern.l n.ise or comes from chaotic sources. The recen.ly in.roduced Mean.to Varian.e logarithmic （MVl） Diagram accoun.s for the spatial variability, bein. very sen.itive to the spatial localization.produced by in.in.tesimal perturbation. of spatiotemporal chaotic systems. By usin. as a ben.hmark a simple model subject to n.ise, we show the distin.t in.ormation.given.by Ran. Histograms an. MVl Diagrams. Hen.e, the main.effects of the extern.l n.ise can.be visualized in.a graphic. From the MVl diagram we clearly observe a reduction.of the amplitude growth rate an. of the spatial localization.（chaos suppression., while from the Ran. Histogram we observe chan.es in.the reliability of the en.emble. We con.lude that in.a complex framework in.ludin. spatiotemporal chaos an. n.ise, both provide a more complete forecastin. picture.

Kin.matic Decoupled Core Paradigm: Coun.errotation.or Just Warpin.

引用

In.ern.tion.l Journ.l of Astron.my an. Astrophysics 2016年第2期6卷 198-205页

作者： Rubén.J. Díaz horacio Dottori ICATE CONICET San Juan Argentina Gemin. Observatory La Serena Chile In.tituto de Física UFRGS Porto Alegre Brazil

Several mechan.sms have been.proposed in.recen. years to explain.kin.matic decoupled cores (KDCs) in.early type galaxies as well as the large differen.es in.an.ular momen.um between.KDCs an. host galaxy. Most of the proposed scen.rios in.olve large fraction. of mergin. even.s, high speed in.eraction. with dwarf spheroidal galaxies, cusp effect of the dark matter den.ity profiles, etc. We here argue that coun.errotation.as well as fast an. slow rotation.of disks or spheroids at the cen.er of galaxies can.also be explain.d by a misalign.en. of the cen.ral spheroid equatorial plan. with regard to that defin.d by the observed extern.l stellar rotation. Con.rary to what happen. at the outer region.of disk galaxies, on.e in.tability has led to the in.er warped core, the perturbed orbits can.main.ain.a common.orien.ation.due to the rigid body like rotation.at the cen.ral region.of the galaxy. The spatial con.iguration.that furn.shes the smallest an.ular momen.um differen.e between.the KDC an. the host galaxy is completely defin.d by observed parameters in.the plan. of the sky, n.mely, the in.lin.tion.of the in.er an. outer disks an. the an.le between.the two lin.s of n.des. As an.example we modeled the paradigmatic an. extreme case of the 2D radial velocity field of n.C 4382 n.cleus. Tilt an.les of the KDC n.t larger than.30 degrees also allow explain.n. fast an. low rotators of the called “Sauron.paradigm” in.a un.fied scen.rio. The maximum for the three parameters, n.mely, velocity of the in.er rotator, differen.e of position.an.le an. differen.e with the outer rotation.velocity of the whole Sauron.sample, are con.isten.ly correlated in.agreemen. with the proposed scen.rio. These quan.ities do n.t correlate with the galaxies magn.tude, mass (sin.e large an. dwarf spheroidals show apparen. coun.errotation.as well) or en.iron.en., also suggestin. that an.in.ern.l phen.men.n.like the cen.ral spheroid warpin., that we are here proposin., may be at work.
