An unsupervised machine-learning workflow is proposed for estimating fractional landscape soils and vegetation components from remotely sensed hyperspectral *** workflow is applied to EO-1 Hyperion satellite imagery collected near Ibirací,Minas Gerais,*** proposed workflow includes subset feature selection,learning,and estimation *** training with landscape feature class realizations provide a hypersurface from which to estimate mixtures of soil(e.g.0.5 exceedance for pixels:75%clay-rich Nitisols,15%iron-rich Latosols,and 1%quartz-rich Arenosols)and vegetation(e.g.0.5 exceedance for pixels:4%Aspen-like trees,7%Blackberry-like trees,0%live grass,and 2%dead grass).The process correctly maps forests and iron-rich Latosols as being coincident with existing drainages,and correctly classifies the clay-rich Nitisols and grasses on the intervening *** classifications are independently corroborated visually(Google Earth)and quantitatively(random soil samples and crossplots of field spectra).Some mapping challenges are the underestimation of forest fractions and overestimation of soil fractions where steep valley shadows exist,and the under representation of classified grass in some dry areas of the Hyperion *** preliminary results provide impetus for future hyperspectral studies involving airborne and satellite sensors with higher signal-to-noise and smaller footprints.

Introduction. Nocardia brasiliensis is a very rarely reported cause of chronic phagedenic ulcerations. We report the case of an elderly woman who developed such an infection after falling on her right leg on the road in the Bresse country (an essentially agricultural and bovine- cattle breading region) and developed a chronic phagedenic ulcer secondarily complicated by nodular lymphangitis of the thigh. Case report. A 75 year- old woman fell on her right leg on the side of themain road outside her hamlet in the Bresse country and secondarily developed a chronique phagedenic ulceration. We first considered her as suffering from pyoderma gangrenosum. A complete scanning only revealed an autoimmune thyroiditis and a rapidly healing gastric ulceration, and none of the treatments, either local or systemic, helped the skin condition to heal. After 3 weeks of application of a local corticoid ointment, the patient developed fever, general malaise, an exacerbation of her wound and an infiltration of the skin round her knee, together with nodular lymphangitic dissemination. A supplementary bacterial swab disclosed massive proliferation of a slow- growing Gram- positive bacillus, which proved to be Nocardia brasiliensis, together with a methicillino- sensitive Staphylococcus aureus. The treatment with sulfamethoxazole- trimetoprim gave a rash after 12 hours and was changed to amoxicillin and clavulanic acid, which rapidly proved to be permanently effective. Discussion. The revelation of this particular slow- growing bacteria is difficult and requires bacterial swabs. Nocardia brasiliensis is relatively rare in primary skin ulcerations andwe discuss the reasons why an elderly women should find this bacteria on the road outside her hamlet in the French countryside. This particular infectious condition requires general scanning, to make sure that the primary skin condition does not extend to other organs. We review the therapeutical options for patients who exhibit allergic react

A/2 screw dislocation is commonly dissociated into two /6 Shockley partial dislocations on{111} planes in face-centered cubic *** the two partials are not purely screw,different mechanisms of cross-slip could take place,depending on the stacking fault energy,applied stress and tempe *** is crucial to classify the mechanisms of cross-slip because each mechanism possesses its own reaction path with a special activation *** this work,molecular dynamics simulations have been performed systematically to explore the cross-slip mechanism under different stresses and temperatures in three different metals Ag,Cu and Ni that have different stacking fault energies of 17.8,44.4 and 126.8 mj/m^2,re *** Ag and Cu with low stacking fault energy,it is observed that the cross-slip mechanism of screw dislocations changes from the Fleischer obtuse angle(FLOA),to the friedel-Escaig(FE),and then to the FL acute angle(FLAA) at low temperatures,with increasing the applied ***,when the temperature increases,the FE mechanism gradually becomes dominant,while the FLAA only occurs at the high stress *** particular,the FLOA has not been observed in Ni because of its high stacking fault energy.

Achalasia has been described following fundoplication and is attributed to vag al nerve damage during surgery. Similarly,other traumatic events to the distal e sophagus may be linked to the development of achalasia. Operative and nonoperati ve trauma as a possible factor in the development of achalasia was studied. A re trospective analysis of patients with achalasia(n = 64) at our institution was p erformed. Collected data included age, gender, symptoms, and history of operativ e and nonoperative traumatic events. Comparisons were made to a group of patient s with similar symptoms but normal esophageal manometry (n = 73). Achalasia was diagnosed by manometry in 125 patients over a 6-year period. All patients with complete medical records (n = 64) were studied. A history of operative or nonope rative trauma to the upper gastrointestinal tract prior to the development of sy mptomatic achalasia was present in 16 of 64 (25%). Significantly fewer patients (9.5%) wi th symptoms of dysphagia, but normalmanometry and upper endoscopy, had precede nt trauma to the upper gastrointestinal tract (P < 0.05).All cases of nonoperati ve trauma occurred in motor vehicle accidents. Cases of operative trauma include d coronary artery bypass surgery (n = 4), bariatric surgery (n = 2), fundoplicat ion(n = 3), hea rt/lung transplantation (n = 1), and others (n =5). Pa tients with proven achalasia and a history of trauma were more likely to have chest pain (RR, 4.5; P = 0.012) but less likely to have regurgitation (RR, 0.51; P = 0.01) or nausea/vomiting(RR, 0.0; P = 0.27) than those without a history of antecedent trauma. In this series, significantly more patients with achalasia h ad a history of preceding trauma than did patients with similar symptoms and nor mal esophageal manometry. Following trauma, patients may be at increased risk fo r developing achalasia, possibly from neuropathic dysfunction due to vagal nerve damage. Patients with posttraumatic achalasia may have symptoms wh

Data sets were collected with the BESⅢ detector at the BEPCⅡ collider at the center-of-mass energy of √s=3.650 GeV during May 2009 and at √s=3.773 GeV from january 2010 to May 2011. By analyzing the large angle Bhabha scattering events, the integrated luminosities of the two data sets are measured to be （44.49±0.02±0.44） pb-1 and （2916.94±0.18±29.17） pb-1, respectively, where the first error is statistical and the second error is systematic.
