The mass ratio of ^(107)Ag in the Ag–In–Cd control rod is 41.44%. To accurately calculate the consumption value of the control rod, a reliable neutron reaction cross section of the ^(107)Ag is required. Meanwhile,^(107)Ag is also an important weak r nucleus. Thus, the cross sections for neutron induced interactions with ^(107)Ag are very important both in nuclear energy and nuclear astrophysics. The(n, γ) cross section of ^(107)Ag has been measured in the energy range of 1–60 eV using a back streaming white neutron beam line at China spallation neutron source. The resonance parameters are extracted by an R-matrix code. All the cross section of ^(107)Ag and resonance parameters are given in this paper as datasets. The datasets are openly available at http://www.doi.org/10.11922/sciencedb.j00113.00010.展开更多

It is found that there is a long single-phase region, Au（Ag） or Ag（Au）, along the Au-Ag binary isomorphous system on the gold-silver-rich side of the 700℃ isothermal section and between the binary compound Au2Dy and Ag2Dy there is the all proportional solid solution, （Au2Dy） or （Ag2Dy）. It is confirmed that the partial 700℃ isothermal section consists of six single-phase regions: solid solution Au（Ag） or Ag（Au）, （Au2Dy） or （Ag2Dy）, Au6Dy, Au51Dy14, Au3Dy and Ag51Dy14; nine binary-phase regions: （Au2Dy）+Au（Ag）, Au6Dy+Au（Ag）, Au（Ag）+Ag51Dy14, Ag51Dy14+（Au2Dy）, Au3Dy+（Au2Dy）, Au3Dy+Au51Dy14, Au51Dy14+Au6Dy, Au51Dy14+Au（Ag） and Au（Ag）+Au3Dy;four ternary regions: Ag51Dy14+（Au2Dy）+Au（Ag）, （Au2Dy）+Au（Ag）+Au3Dy, Au（Ag）+Au3Dy+Au51Dy14 and Au51Dy14+Au（Ag）+Au6Dy. No new ternary compound is formed in the gold-silver-rich field（Dy≤35%） of the Au-Ag-Dy ternary system.展开更多

This extension has led to an increase in the aging population in Japan and globally. Providing appropriate long-term care (LTC) for PLWH has thus become increasingly critical. Our study aimed to describe LTC setting preferences and related factors among middle-aged and older Japanese people living with HIV. A cross-sectional survey was conducted at two hospitals in Tokyo. One hundred seventy-five outpatients aged 40 years and above participated in this study. Participants completed an anonymous self-administered questionnaire to assess where they wanted to live once they could no longer care for themselves. Approximately 52.0% preferred a designated facility for older adults or LTC, while 30.3% preferred their home or living with family, a partner, or a friend (“familiar housing”). Bivariate analyses revealed that LTC setting preference was significantly associated with marital status, whether or not the participant had at least one child, and household composition. Furthermore, logistic regression analysis revealed that participants living with non-kin were less likely to prefer living in designated housing facilities for older adults or LTC (adjusted odds ratio = 0.17, 95% confidence interval: 0.05 - 0.63). The study findings suggest that family make-up and composition of cohabiters are critical indicators for LTC setting preference in this population. These findings can be the foundation for future care planning and delivery to meet the unique LTC needs and expectations of the aging population with HIV in Japan and similar global settings.展开更多
