Putin\u27s \u27Eastern Pivot\u27: Divergent Ambitions between Russia and China? Evidence from the Arctic
Focusing upon the warming Sino-Russian relationship in general, this paper also examines in particular both countries interests in the Arctic region. The paper begins with a brief overview of the developing Sino-Russian relationship since the late 1980s. After discussing the blossoming of friendlier ties during the Putin-Xi era, it reviews some of the arguments and assumptions that scholars have held predicting either an ever closer relationship or an eventual rupture in those relations. The paper then analyzes both countries’ interests in the Arctic realm, using this case study as evidence supporting the view that the Sino-Russian relationship–despite its many difficulties–has been effectively managed in this arena for mutual benefit. As well, although it was not intended to be so, the sanctions regime imposed by America and her European allies has been a key driver in the closer Arctic relationship, in specific, and Sino-Russian relations, in general

Co-existing structures in 105Ru
New positive-parity states, having a band-like structure, were observed in
105Ru. The nucleus was produced in induced fission reaction and the prompt
gamma-rays, emitted from the fragments, were detected by the EUROBALL III
multi-detector array. The partial scheme of excited 105Ru levels is analyzed
within the Triaxial-Rotor-plus-Particle approach

Compensation in Preclinical Huntington's Disease: Evidence From the Track-On HD Study
BACKGROUND:
Cognitive and motor task performance in premanifest Huntington's disease (HD) gene-carriers is often within normal ranges prior to clinical diagnosis, despite loss of brain volume in regions involved in these tasks. This indicates ongoing compensation, with the brain maintaining function in the presence of neuronal loss. However, thus far, compensatory processes in HD have not been modeled explicitly. Using a new model, which incorporates individual variability related to structural change and behavior, we sought to identify functional correlates of compensation in premanifest-HD gene-carriers.
METHODS:
We investigated the modulatory effects of regional brain atrophy, indexed by structural measures of disease load, on the relationship between performance and brain activity (or connectivity) using task-based and resting-state functional MRI.
FINDINGS:
Consistent with compensation, as atrophy increased performance-related activity increased in the right parietal cortex during a working memory task. Similarly, increased functional coupling between the right dorsolateral prefrontal cortex and a left hemisphere network in the resting-state predicted better cognitive performance as atrophy increased. Such patterns were not detectable for the left hemisphere or for motor tasks.
INTERPRETATION:
Our findings provide evidence for active compensatory processes in premanifest-HD for cognitive demands and suggest a higher vulnerability of the left hemisphere to the effects of regional atrophy
Observation of Positive-Parity Bands in Pd and Pd: Enhanced -Softness
The neutron-rich nuclei Pd and Pd were produced as fission
fragments following the Si + Er reaction at 142 MeV. Using the
identification based on the coincidences with the complementary fission
fragments, the only positive-parity bands observed so far in Pd and
Pd emerged from this work. A band, built on top of the 5/2 ground
state exhibiting = 1 energy-level staggering, was observed in each
of these nuclei. Both nuclei of interest, Pd and Pd, are
suggested to lie in the transitional region of Pd isotopes of maximum
-softness. The ground states of both nuclei are predicted by TRS
calculations to be extremely -soft with shallow triaxial minima. The
first crossing in the new bands is proposed to be due to an alignment of
neutrons

Spectroscopy of low-spin states in 157Dy : Search for evidence of enhanced octupole correlations
CITATION: Majola, S. N. T., et al. 2019. Spectroscopy of low-spin states in 157Dy : Search for evidence of enhanced octupole correlations. Physical Review C, 100(6):034322, doi:10.1103/PhysRevC.100.034322.The original publication is available at https://journals.aps.org/prcLow-spin states of ¹⁵⁷Dy have been studied using the JUROGAM II array, following the ¹⁵⁵Gd (α, 2n) reaction at a beam energy of 25 MeV. The level scheme of ¹⁵⁷Dy has been expanded with four new bands. Rotational structures built on the [523]5/2⁻ and [402]3/2⁺ neutron orbitals constitute new additions to the level scheme as do many of the inter- and intraband transitions. This manuscript also reports the observation of cross I⁺ →(I–1) ⁻ and I⁻ →(I–1)⁺ E1 dipole transitions interlinking structures built on the [523]5/2⁻ (band 5) and [402]3/2⁺ (band 7) neutron orbitals. These interlacing band structures are interpreted as the bands of parity doublets with simplex quantum number s=–i related to possible octupole correlations.https://journals.aps.org/prc/abstract/10.1103/PhysRevC.100.034322Publisher's versio
