Reaction- and interaction cross sections of 17C on a carbon target have been reanalyzed by use of the modified Glauber model. The analysis with a deformed Woods-Saxon density/potential suggests a big deformation structure for 17C. The existence of a tail in the density distribution supports its possibility of being a one-neutron halo structure. Under a deformed core plus single-particle assumption, analysis shows a dominant d-wave of the valence neutron in 17C. Key words Cross section, Glauber model, Density distribution, Halo, Deformation.arXiv:1305.0169v1 fatcat:lhlmjprubjbvveyzhkg4cqfv5u

In clinical, Psychotria serpens L. was often substitute for Caulis trachelospermi to treat cancer in China. Meanwhile, EtOAc and n-BuOH fractions of MeOH extract of P. serpens L. show power activity against H460, HepG2, Hela, and PC9/GR cell lines, and no toxic effects against normal 16HBE cell lines. In our ongoing search for bioactive novel compounds from Chinese material medica, one new type of glycosylsphingolipids Psychotramide (1a–1c) were isolated from P. serpens L., and their structuresdoi:10.6084/m9.figshare.7739087 fatcat:s6gx7a2rtnhw7jxyyyyg3jpqsq

Garcinia xanthochymus has been widely used in traditional Chinese medicine for expelling worms and removing food toxins. Bioassay-guided fractionation of an EtOAc-soluble extract of G. xanthochymus stem bark led to the isolation of six new xanthones. Their structures were elucidated by spectroscopic methods, especially 2D-NMR techniques. Free-radical-scavenging activities of the isolated compounds were elucidated through DPPH method. Most of the isolated compounds showed considerable freedoi:10.3390/molecules15107438 pmid:20966883 pmcid:PMC6259097 fatcat:tuizso6sn5ebzbo3p3lmmmsize

Compound 1 exhibited effective antioxidant scavenging activity against DPPH radical with an IC 50 value of 19.64 μM, and compound 6 showed the lowest activity among all the tested molecules, with an IC 50 value of 66.88 μM. These findings support the notion that the plant genus Garcinia is a good source of bioactive compounds.
Based on quasi-static electromagnetic field theory, recently grounding system under alternative currents (AC) substation has been studied with equal potential and unequal potential models. In these numerical models, the closed form of Green's function for a point source within a horizontal multilayered earth model and its quasistatic complex image method have been fully discussed. However, less information about how to achieve the closed form of Green's function through Matrix Pencil method isdoi:10.2528/pierb11060301 fatcat:s7rgux5rm5f5dilmiesif7zqny

We reported a case of huge gastric phytobezoar. The gastric phytobezoar was successfully removed through gastrotomy after two failed attempts in endoscopic fragmentation and removal. Disopyrobezoars could be treated either conservatively or surgically. Gastrotomy or laparoscopical management is recommended for the treatment of huge disopyrobezoars.doi:10.3748/wjg.14.152 pmid:18176981 pmcid:PMC2673384 fatcat:covaea5winbunesqfdldvww2ju

We report positions, velocities, and metallicities of 50 ab-type RR Lyrae (RRab) stars observed in the vicinity of the Orphan stellar stream. Using about 30 RRab stars classified as being likely members of the Orphan stream, we study the metallicity and the spatial extent of the stream. We find that RRab stars in the Orphan stream have a wide range of metallicities, from −1.5 dex to −2.7 dex. The average metallicity of the stream is −2.1 dex, identical to the value obtained by Newberg et al.doi:10.1088/1674-1056/17/1/036 fatcat:ny64detmizbklg65pczowib7iq

We find that the most distant parts of the stream (40-50 kpc from the Sun) are about 0.3 dex more metal-poor than the closer parts (within ∼30 kpc), suggesting a possible metallicity gradient along the stream's length. We have extended the previous studies and have mapped the stream up to 55 kpc from the Sun. Even after a careful search, we did not identify any more distant RRab stars that could plausibly be members of the Orphan stream. If confirmed with other tracers, this result would indicate a detection of the end of the leading arm of the stream. We have compared the distances of Orphan stream RRab stars with the best-fit orbits obtained by Newberg et al. We find that model 6 of Newberg et al. cannot explain the distances of the most remote Orphan stream RRab stars, and conclude that the best fit to distances of Orphan stream RRab stars and to the local circular velocity is provided by potentials where the total mass of the Galaxy within 60 kpc is M 60 ∼ 2.7 × 10 11 M , or about 60% of the mass found by previous studies. More extensive modeling that would consider non-spherical potentials and the possibility of misalignment between the stream and the orbit is highly encouraged.
