The aim of this Erratum is to update Fig. 2 in our original article. In the published Fig. 2, the plotted data for the WeizsackerSkyrme (WS) model correspond to the nuclear charge radii by assuming that all the nuclides in the isotopic chains of Z = 40 and 41 are spherical. These data were calculated with Eq. (2) in Ref. [1] (Ref. [13] in the original article).It is found that to include the corrections of nuclear deformations in the WS model would result in significant improvements in the charge radii for nuclei around the kink at N % 60 in both the isotopic chains. The corrected charge radii with deformations can be calculated with Eq. (1) in Ref. [ 1 ]. We label the charge radius data without and with deformation corrections by WS(Sph.) (i.e., the data in the original article) and WS(Def.), respectively. The original Fig. 2 should thus be replaced by the figure given below. The discussion and conclusions in the original article remain valid. FIG. 2. (Color online) Comparisons of predictions in nuclear charge radii and available experimental data for (a) Z = 40 and (b) 41 isotopic chains. The importance of the deformation effect in the WS model is clearly shown by the curves labeled by WS(Sph.) and WS(Def.).We would like to thank N. Wang for making us aware of this correction.[1] N.

This article investigates China's bilateral diplomacy in the Arctic towards the USA, Canada, Denmark/Greenland, Norway, Russia and Iceland. In seeking to identify (1) the most important bilateral issues, (2) whether China's diplomacy towards some of Arctic states has been more successful than others, and (3) the long-term goals of China's Arctic diplomacy and presence, the article utilizes insights from theories of diplomacy in IR as well as the particular historical experiences of the PRC. It concludes with identifying how Beijing's utmost concern when it comes to foreign policy still centers on promoting economic benefits and creating a global presence conducive to economic growth. Yet, while economic factors undoubtedly preoccupy Chinese decision-making in the Arctic, Chinese representatives currently speak less about economic development than about their environmental concerns. Chinese footprints in the Arctic have been adequately established primarily in the scientific research field, while commerce and multilateral governance are secondary. Further, it is also apparent that China has been developing contracts with the smaller Arctic powers of Denmark and Iceland (and earlier also attempted to do so with Norway) to facilitate collaborations in both Arctic research as well as economic development. With the bigger Arctic powers, such as the USA and Russia, China appears to prioritize other, more pressing bilateral issues than those pertaining solely to the Arctic.

Guided by insights from IR theory, this article investigates China's adherence to the UN Convention of the Law of the Sea (UNCLOS), asking how Beijing's attitude towards UNCLOS affects China's role in Arctic governance and beyond. Examining contested Law of the Sea mattersthe dispute over the "nine-dash line" in the South China Sea, the right of innocent passage of warships, the role of international arbitrationit argues that China's compliance with UNCLOS does matter for understanding how China is perceived as a member of the international community. Further, China's growing interests and enhanced engagement in the Arctic depend on a strong international legal framework; Arctic governance encapsulates the norms of multilateralism and rule of law. The article concludes by asking whether Chinese experiences from observing and participating in the multilateral governance of the Arctic can serve as an example of successful multilateral cooperation and peaceful conflict solution, of relevance to China also in its nearby maritime regions.

The recent progress on the self-consistent tilted axis cranking model based on the covariant density functional theory with point-coupling interaction and its application to the antimagnetic rotation (AMR) in nuclei are briefly reported. In particular, the microscopic description of the newly observed AMR band in 105 Cd is discussed. Without any additional parameter, the experimental B(E2) values are reproduced very well. Moreover, the appearance of the "twoshears-like" mechanism in the AMR band is clearly seen.
