Carbon Trading in BRICS Countries: Challenges and Recommendations
As one of the world’s largest emerging economies, BRICS countries are playing an increasingly important role in addressing the global issue of climate change. To achieve their emissions reduction targets, these nations are actively promoting the construction of carbon trading markets. However, they face multiple challenges and obstacles in this endeavor, including issues related to market norms, financial support, technical capacity, social participation, and development needs. This research investigates the problems and challenges faced by BRICS countries in terms of building carbon trading markets through literature reviews and case studies. To address these challenges, this research strengthening international cooperation and technical support, improving market norms and provide following recommendations: conducting regulatory measures, enhancing social participation and communication, and balancing the relationship between economic development and environmental protection requirements. Furthermore, it is crucial for these nations to continue to strengthen international cooperation and collaboration, working together to promote the construction of carbon trading markets, achieving their emissions reduction targets, and ensuring long-term sustainability and economic development
DataChat: Prototyping a Conversational Agent for Dataset Search and Visualization
Data users need relevant context and research expertise to effectively search
for and identify relevant datasets. Leading data providers, such as the
Inter-university Consortium for Political and Social Research (ICPSR), offer
standardized metadata and search tools to support data search. Metadata
standards emphasize the machine-readability of data and its documentation.
There are opportunities to enhance dataset search by improving users' ability
to learn about, and make sense of, information about data. Prior research has
shown that context and expertise are two main barriers users face in
effectively searching for, evaluating, and deciding whether to reuse data. In
this paper, we propose a novel chatbot-based search system, DataChat, that
leverages a graph database and a large language model to provide novel ways for
users to interact with and search for research data. DataChat complements data
archives' and institutional repositories' ongoing efforts to curate, preserve,
and share research data for reuse by making it easier for users to explore and
learn about available research data.Comment: 6 pages, 2 figures, and 1 table. Accepted to the 86th Annual Meeting

Experimental determination of the energy per particle in partially filled Landau levels
We describe an experimental technique to measure the chemical potential,
, in atomically thin layered materials with high sensitivity and in the
static limit. We apply the technique to a high quality graphene monolayer to
map out the evolution of with carrier density throughout the N=0 and N=1
Landau levels at high magnetic field. By integrating over filling factor,
, we obtain the ground state energy per particle, which can be directly
compared with numerical calculations. In the N=0 Landau level, our data show
exceptional agreement with numerical calculations over the whole Landau level
without adjustable parameters, as long as the screening of the Coulomb
interaction by the filled Landau levels is accounted for. In the N=1 Landau
level, comparison between experimental and numerical data reveals the
importance of valley anisotropic interactions and the presence of
valley-textured electron solids near odd filling.Comment: 14 pages, 11 figure

Cascade of multi-electron bubble phases in monolayer graphene at high Landau level filling
The phase diagram of an interacting two-dimensional electron system in a high
magnetic field is enriched by the varying form of the effective Coulomb
interaction, which depends strongly on the Landau level index. While the
fractional quantum Hall states that dominate in the lower energy Landau levels
have been explored experimentally in a variety of two-dimensional systems, much
less work has been done to explore electron solids owing to their subtle
transport signatures and extreme sensitivity to disorder. Here we use chemical
potential measurements to map the phase diagram of electron solid states in
, , and Landau levels in monolayer graphene. Direct comparison
between our data and theoretical calculations reveals a cascade of
density-tuned phase transitions between electron bubble phases up to two, three
or four electrons per bubble in the N=2, 3 and 4 Landau levels respectively.
Finite temperature measurements are consistent with melting of the solids for
T1K.Comment: 5 pages, 4 figures in main text, 7 pages, 3 figures in supplementary
