China’s industrial carbon emissions: Historical drivers at the regional and sectoral levels and projections in light of policy targets
Has the industrial sector in China effectively been decarbonizing in recent years, across different regions and subsectors, and is it plausible that it will reduce its CO2 emissions in conformity with national and internationally pledged emission goals?

Applications of AdS/CFT to strongly correlated matter: from numerics to experiments
What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

Tromble, From Nomadic Traditionalists to Sedentary Scripturalists? Reexamining Ethno-Religious Discourse in Central Asia
Religion and ethnicity are inextricably linked in discourse within and about Central Asia. One common narrative suggests that as a result of differences between historically sedentary and nomadic populations, ethnic Tajiks and Uzbeks are naturally more religious and more likely to radicalise than their…
