Phys Rev Lett. 2013 Mar 08;110(10):107204. doi: 10.1103/PhysRevLett.110.107204. Epub 2013 Mar 07.

We investigate the two-dimensional highly spin-polarized electron accumulation layers commonly appearing near the surface of n-type polar semiconductors BiTeX (X=I, Br, and Cl) by angular-resolved photoemission spectroscopy. Because of the polarity and the strong spin-orbit interaction built in the...

Sci Rep. 2016 Sep 23;6:33995. doi: 10.1038/srep33995.

Regional brain sizes of very-preterm infants at term-equivalent age differ from those of term-born peers, which have been linked with later cognitive impairments. However, dependence of regional brain volume loss on gestational age has not been studied in detail....

Inorg Chem. 2016 Apr 04;55(7):3674-9. doi: 10.1021/acs.inorgchem.6b00247. Epub 2016 Mar 23.

The novel oxysulfides La2Ta2ZrS2O8 (LTZSO), La2Ta2TiS2O8 (LTTSO), and La2Nb2TiS2O8 (LNTSO) were synthesized, and their crystal structures, electronic structures, and photocatalytic activities for water splitting under visible light were investigated. Density functional theory calculations showed that these compounds are direct-band-gap...

Ultrafast time-resolved electron diffraction revealing the nonthermal dynamics of near-UV photoexcitation-induced amorphization in Ge2Sb2Te5.

Because of their robust switching capability, chalcogenide glass materials have been used for a wide range of applications, including optical storages devices. These phase transitions are achieved by laser irradiation via thermal processes. Recent studies have suggested the potential...

Utility of Glissonean Pedicle Transection for Surgical Treatment of Severe Liver Trauma.

Case reports in gastroenterology

Koizumi S, Katsumata K, Ono T, Segami K, Hoshino H, Katayama M, Kobayashi S, Matsumoto J, Fujitani S, Taira Y, Otsubo T.
PMID: 28512392
Case Rep Gastroenterol. 2017 Apr 10;11(1):190-200. doi: 10.1159/000468514. eCollection 2017.

The most common initial strategy for treatment of severe liver trauma is damage control in which hemostasis is achieved by perihepatic gauze packing and/or vascular embolization. However, we encounter patients in whom this strategy alone is not adequate. We...

Inheritance of low pasting temperature in sweetpotato starch and the dosage effect of wild-type alleles.

Breeding science
