Intrinsic Properties of AFe2As2 (A = Ba, Sr) Single Crystal under Highly Hydrostatic Pressure Conditions
We measured the electrical resistivity and ac magnetic susceptibility of
BaFe2As2 and SrFe2As2 single crystals under pressure using a cubic anvil
apparatus. For BaFe2As2, the antiferromagnetic (AF) and structural transitions
are suppressed with increasing pressure. Unexpectedly, these transitions
persist up to 8 GPa, and no signature of a superconducting transition was
observed in the pressure range investigated here. On the other hand, the AF and
structural transitions of SrFe2As2 collapse at around the critical pressure Pc
~ 5 GPa, resulting in the appearance of bulk superconductivity. The
superconducting volume fraction abruptly increases above Pc, and shows a dome
centered at approximately 6 GPa. Our results suggest that the bulk
superconducting phase competes with the AF/orthorhombic phase and only appears
in the narrow pressure region of the tetragonal phase.Comment: 4 pages, 4 figures; accepted for publication in J. Phys. Soc. Jp
Rare books about Masuzawa Bunko Collection of CSAC
Last year, Center of Studies of Asian cultures (CSAC) created Masuzawa Bunko. Masuzawa Akiko that is sometime professor in Japan University and he presented his collection which comprises about 10,000 volumes for our Center. There are many rarely books about History of Education in Modern Chines. This time I would like to introduce some rarely books in Masuzawa Bunko, in addition to provide a research chance for our readers,東アジアの言語と表象文部科学省グローバルCOEプログラム 関西大学文化交渉学教育研究拠

Contrasting Pressure Effects in Sr2VFeAsO3 and Sr2ScFePO3
We report the resistivity measurements under pressure of two Fe-based
superconductors with a thick perovskite oxide layer, Sr2VFeAsO3 and Sr2ScFePO3.
The superconducting transition temperature Tc of Sr2VFeAsO3 markedly increases
with increasing pressure. Its onset value, which was Tc{onset}=36.4 K at
ambient pressure, increases to Tc{onset}=46.0 K at ~4 GPa, ensuring the
potential of the "21113" system as a high-Tc material. However, the
superconductivity of Sr2ScFePO3 is strongly suppressed under pressure. The
Tc{onset} of ~16 K decreases to ~5 K at ~4 GPa, and the zero-resistance state
is almost lost. We discuss the factor that induces this contrasting pressure
effect.Comment: 5 pages, 4 figures, to be published in J. Phys. Soc. Jpn. No.12

Benefit of adjuvant immunotherapy in renal cell carcinoma: A myth or a reality?
Background The benefit of adjuvant immunotherapy after nephrectomy in renal cell carcinoma (RCC) is controversial. The present study aimed to examine the possible benefit of adjuvant immunotherapy in various clinical settings. Methods We retrospectively reviewed 436 patients with pT1-3N0-2M0 RCC who underwent radical or partial nephrectomy with curative intent at our institution between 1981 and 2009. Of them, 98 (22.5%) patients received adjuvant interferon-α (IFN-α) after surgery (adjuvant IFN-α group), while 338 (77.5%) did not (control group). The primary endpoint was cancer-specific survival (CSS). Univariate and multivariate analyses were conducted using log-rank tests and Cox proportional hazards models, respectively. Results Fifty-two (11.9%) patients died from RCC with a median follow-up period of 96 months. Preliminary univariate analyses comparing CSS among treatment groups in each TNM setting revealed that CSS in the control group was equal or superior to that in the adjuvant IFN-α group in earlier stages, while the opposite trend was observed in more advanced stages. We evaluated the TNM cutoffs and demonstrated maximized benefit of adjuvant IFN-α in patients with pT2b-3cN0 (P = 0.0240). In multivariate analysis, ôpT3 and pN1-2 were independent predictors for poor CSS in all patients. In the subgroups with ôpT2 disease (n = 123), pN1-2 and no adjuvant treatment were significant poor prognostic factors. Conclusions Adjuvant immunotherapy after nephrectomy may be beneficial in pT2b-3cN0 RCC. Careful consideration is, however, required for interpretation of this observational study because of its selection bias and adverse effects of IFN-α
Study of quantum effects on atomic displacements in quartz
金沢大学理工研究域数物科学系The crystal structure of quartz (SiO2) was analyzed by neutron powder diffraction at several temperatures in the range of 10–250 K. The temperature dependence of the structure parameters was consistent with our previous results obtained using single-crystal X-ray diffraction above room temperature. Atomic displacements are order parameters for displacive structural phase transitions. The temperature evolution of Si atomic displacement in quartz was analyzed by studying the quantum expansion of the Landau potential. The expansion was found to accurately describe the evolution of the atomic displacement over the entire temperature interval. To the best of our knowledge, such a verification of atomic displacement is the first of its kind. A proportional relationship between spontaneous strain and the square of the atomic displacement was observed over the entire temperature interval. The validity of the obtained characteristic temperature for the quantum effect is discussed and compared with the results of previous Raman-scattering studies
Effect of Uniaxial Stress for Pressure-Induced Superconductor SrFe_2As_2
We report that the pressure-temperature phase diagram of single-crystalline
SrFeAs is easily affected by the hydrostaticity of a
pressure-transmitting medium. For all of the three mediums we used,
superconductivity with zero resistance appears, accompanied by the suppression
of an antiferromagnetic (orthorhombic) phase, but the critical pressure
was found to depend on the type of medium. was estimated to be 4.4 GPa
under almost hydrostatic condition, but it decreased to GPa with the
use of the medium already solidified at room temperature. The uniaxial stress
along the c-axis is suggested to aid in the suppression of the
antiferromagnetic (orthorhombic) phase. The pressure effect of BaFeAs
is also reported.Comment: 4 pages, 5 figures, to be published in J. Phys. Soc. Jpn. No.8 (2009
Trajetórias de uso e cobertura da terra nas microrregiões de Marabá, Paragominas e Tucuruí, sudeste paraense (2004 - 2014).
O processo de ocupação na região do Sudeste Paraense inicia no final do século XIX e desde de então, o uso e cobertura da terra tem passado por transformações profundas. Avaliou-se um conjunto de municípios das microrregiões Paragominas, Tucuruí e Marabá, do Sudeste Paraense a partir de matrizes TerraClass de uso e cobertura da terra, compreendendo os anos de 2004, 2010 e 2014, sendo propostas trajetórias a partir da intersecção dos dados entre os anos selecionados. A manutenção da cobertura florestal foi a trajetória com maior poder discriminante entre os municípios, seguida de outras trajetórias associadas a pecuária ou vegetação secundária. A microrregião Tucuruí apresentou a maior homogeneidade entre os seus municípios, enquanto que as outras denotaram segmentaçã
