Summary: This paper presents a method for real-time motion capture using a single LiDAR sensor. The proposed autoregressive conditional variational autoencoder model learns pose prior knowledge and generates plausible current poses using a feature encoder and a pose generator. Experimental results demonstrate the accuracy of predicted poses and the consideration of temporal coherence across frames.

Summary: Supersonic decarburization, a clean CCUS technology using non-equilibrium condensation and swirling separation, is investigated through numerical simulation. The results show that higher pressure, inlet temperature, and mole fraction of CO2 facilitate the condensation process. For separation performance, increasing the mass concentration of inlet heterogeneous droplets improves carbon separation and reduces exergy loss of condensed CO2. This concept has potential applications in offshore natural gas processing for carbon capture.

Summary: This study analyzed the reporting landscape of carbon capture utilization and storage (CCUS) technology in Chinese newspapers. The results showed that while the media generally took an affirmative stance towards CCUS, there were technical misperceptions and a lack of comprehensive coverage in news presentations. The study also revealed the close relationship between CCUS-related policies and media coverage.

Summary: In order to fulfill the Paris Agreement, CO2 capture technologies must be developed to reduce Green House Gas emissions. Adsorption is considered a viable technology due to its mild conditions. Selective sorbents with high CO2 adsorption capacities are needed. This study used branched poly-ethylenimines (PEI) with different average molecular weights, agglomerated with silica at different weight percentages. Adsorption was measured and kinetic parameters were estimated. The results showed that the materials produced were selective and had potential use in adsorption processes, with the sample of the lowest average molecular weight having the highest adsorption capacity.

Summary: A new methodology for evaluating commercial adsorbents for CO2 capture using temperature swing adsorption has been developed. The study found that binderless zeolites performed better in CO2 production and desorption energy compared to their binder-based counterparts. The 13XBL binderless zeolite had the highest CO2 production and lowest desorption energy, while the 5A zeolites had the lowest CO2 production and highest desorption energy among the zeolites.

Summary: This study examines the independent and concomitant role of temperature and pressure in determining CO2 mass transport and selectivity in biogas upgrading. The results show that pressurisation is crucial for enhancing CO2 flux and selectivity when microporous or nonporous membranes are used. This process intensification reduces energy consumption and methane losses, making it a competitive solution for biogas upgrading.

Summary: This paper investigates the opportunities to use carbon capture and storage (CCS) in Vietnam's power and industry sectors to reduce carbon emissions. The results show that Vietnam's power sector emits 136 Mtpa CO2 and the industry sector emits 88 Mtpa CO2. The nearby sedimentary basins have sufficient storage capacity to store 831 years of CO2 emissions. Additionally, there is potential for CO2 enhanced oil recovery and enhanced gas recovery, which could recover 1058 MMbbl and 95 MMbbl of oil from oil fields and gas fields, respectively. The study proposes establishing four CCS hubs to connect regional CO2 sources and sinks, which could remove up to 142 Mtpa CO2 or 64% of Vietnam's stationary emissions.

Summary: In this study, an entropy-based framework was proposed to construct city-level MRIO tables, and a sensitivity analysis was conducted on the carbon footprint of cities in China's Hebei province. A comparison of consumption-based emissions between the new MRIO and individual city input-output tables revealed a large discrepancy due to conflicting benchmark data used in the two tables.

Summary: The consumption of senior citizens in developed countries has a significant impact on global carbon mitigation, but this impact is not well understood. Research shows that seniors have been increasing their contribution to greenhouse gas emissions over the past decade and are expected to become the largest contributors. In particular, seniors in the United States and Australia have a carbon footprint double the Western average. Changes in expenditure patterns of seniors are the main cause of this trend. While the increasing carbon footprint of seniors may drive domestic production, its effects on international carbon leakage are limited. This demographic change presents more challenges in local mitigation and calls for deeper public mitigation efforts.

Summary: China's increasing role in global climate change mitigation is highlighted in this study, which provides comprehensive CO2 emission inventories for 287 Chinese cities from 2001 to 2019. The study reveals the emission trends and driving forces in these cities, showing that some cities have proactively peaked their emissions through efficiency improvements and energy use changes, while others passively decreased emissions through economic recession or population loss. The study emphasizes the need for passively emission declined cities to address the reasons behind emission decline and utilize low-carbon targets for economic recovery and carbon mitigation. Proactively peaked cities should seek strategies to maintain emission reductions and serve as successful models for cities with growing emissions.

Summary: Chinese cities play a crucial role in national and global carbon reduction efforts, but disparities between cities hinder overall progress. This study analyzes supply chains of Chinese cities and reveals significant carbon inequalities, with the wealthiest cities having carbon footprints comparable to the US while many others fall below the global average. By adopting differentiated low-carbon transition strategies, super-emitting cities have the potential to achieve substantial mitigation and raise living standards in other areas.

Summary: Despite global conservation initiatives, unfragmented intact forest landscapes (IFLs) continue to be lost due to various economic activities. Non-agricultural products are major contributors to IFL loss, with over 60% linked to final consumption. Export, primarily from Russia, Canada, and tropical regions, accounts for more than one-third of IFL loss, with logging and mining as the major causes. It is crucial for governments to engage and intervene in supply chains to address the dispersed drivers of IFL loss and their indirect links to individual consumers.

Summary: Understanding the impact of climate fiscal policies on vulnerable groups, especially the elderly, is crucial for equitable climate mitigation. This study quantifies and compares the distributional impacts of carbon pricing on different age-income groups in various countries, revealing that the elderly, particularly the low-income elderly, are more vulnerable to carbon pricing than younger groups in the same income bracket. The findings highlight the need for targeted social protection and climate mitigation policies to address the high vulnerability of the low-income elderly to carbon pricing.

A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
