Nonreciprocal charge transport in polar Dirac metals with tunable spin-valley coupling by M. Kondo, M. Kimata, M. Ochi, T. Kaneko, K. Kuroki, K. Sudo, S. Sakaguchi, H. Murakawa, N. Hanasaki, H. Sakai

“…For X=Sb with a pair of single-type valleys, the nonreciprocal resistivity increases monotonically with decreasing temperature, while for X=Bi with multiple types of valleys it is reduced by about an order of magnitude and exhibits a peak at a low temperature. Theoretical calculations indicate that the nonreciprocal resistivity is sensitive not only to the spin-momentum (spin-valley) coupling but also to the Fermi energy and the Dirac dispersion. …”

The Predicament of Ethnic Federal System by Yohannes Getahun

“…Answering that, the paper has given due consideration to the practices of defunct, fragile and mature ethnic federations and to the relevant conceptual and theoretical-back standings. The differences in the viabilities of these federations have shown the complicacy of ethnic federalism in meeting with the convulsive interplay between ethnic conflicts and federal system stability. …”

Mechanical Effects of Solid Water on the Particle Skeleton of Soil: Mechanism Analysis by Xiaomeng Duan

“…By defining the concepts of “solid water” and “particle skeleton” after a brief review on adsorbed water, therefore, the mechanical mechanism about how solid water affects the deformation and strength of particle skeleton is theoretically clarified, which could be the physical basis of the reasonability of two assumptive conditions for effective stress equation. …”

A Splay Tree-Based Approach for Efficient Resource Location in P2P Networks by Wei Zhou, Zilong Tan, Shaowen Yao, Shipu Wang

“…We analyze the hop count of the adaptive routing algorithm, as compared to Chord variants, and demonstrate sharp upper and lower bounds for both worst-case and average case settings. In addition, we theoretically analyze the hop reducing in SChord and derive the fact that SChord can significantly reduce the routing hops as compared to Chord. …”

Belarus’ Sovereignty in Question: Assessing its de facto Sovereign Status in the Shadow of Russia by Arūnas Molis, Sara Pastorello

“…While sovereign states exercise full autonomy and control over their affairs, satellite states often find themselves in a subordinate position, heavily influenced or even dominated by external powers. A theoretical framework deconstructs the concept of sovereignty into four crucial elements: authority, legitimacy, independence, and territoriality, which provide a structured assessment of the level of sovereignty in a state and serve as the basis for our analysis. …”
