Summary: We present experimental measurements of cluster sizes formed by supersonic expansion of two different species based on the time-of-flight principle. Argon clusters containing aromatic molecules were ionized with 266 nm wavelength at a low laser intensity. An increased sensitivity of a microchannel plate detector was achieved by accelerating the heavy cluster ions with high voltage. Our measurements of argon clusters, neat molecular clusters, and molecular-Ar clusters, are qualitatively in agreement with predictions from the scaling law, but the fitting exponents for the dependence of cluster sizes on both the stagnation pressure and temperature are different.

Summary: We generalize Taylor's law to heavy-tailed distributions with tail index alpha in (0, 1) and infinite mean, demonstrating specific relationships between sample statistics and sample mean as sample size increases. These scaling relationships characterize the risk-adjusted performance of investments and are known as Taylor's law in ecology and fluctuation scaling in physics.

Summary: This study reveals that the energy dissipation rate in a nonequilibrium reaction system has an inverse power-law dependence on the number of microscopic states in a coarse-grained state, and requires self-similarity of the underlying network. The scaling exponent of the dissipation law depends on the network structure and the probability flux correlation. The existence of the inverse dissipation scaling law is demonstrated in realistic biochemical systems such as biochemical oscillators and microtubule-kinesin active flow systems.

Summary: This article analyzes the carbon emission standards and efficiency of Chinese cities from 2006 to 2017, and finds a stable relationship between urban population scale and carbon emissions. The study also reveals significant spatial heterogeneity in carbon emission efficiency and certain temporal changes.

Summary: This study examines the relationship between energy consumption and economic growth in China from 1980 to 2011, as well as the situation in the Eastern, Middle, and Western regions of China from 1980 to 2008. Significant regional differences in energy intensity were found, and the overall results do not support the hypothesis that China's energy use accords with the biological relationship mentioned. Alternative relationships were found to provide a better fit to the data.

Summary: While the impact of water availability on vegetation and soil microbial activity is well understood, the influence of aridity on carbon patterns in ecosystems is not fully known. Through dimensional analysis and scaling of global terrestrial carbon stocks, we find a self-similar behavior with the dryness index, indicating a strong coupling between the hydrological cycle and biogeochemical process. When normalized by the corresponding hydroclimatic regime, the carbon stock distributions collapse into a double Pareto lognormal distribution, highlighting similarities with income distribution in economics.

Summary: This paper investigates the dynamic behavior of a mechanical system coupled to a Nonlinear Energy Sink (NES) near the fold point of its critical manifold, obtaining a scaling law for the slow flow dynamics and a new theoretical prediction of the mitigation limit. The study simplifies the governing equations of the coupled system, derives the slow flow using the complexification-averaging method, and utilizes the center manifold theorem to obtain the reduced form of the slow flow which reveals a nontrivial dependence involving fractional exponents. Finally, the proposed methodology is numerically validated using an aeroelastic aircraft wing model coupled to one NES.

Summary: This study explores the anode performance of N-, P-, and As-doped GDYs using first-principles calculations. The results show that doping can improve the theoretical capacity of GDY. The study also demonstrates the good thermal stability of doped GDYs and the similarity of Li diffusion barriers to perfect GDY.

Summary: The study used a discrete choice experiment to estimate the trade-offs the Polish population is willing to make for energy reform regarding carbon reduction. Respondents prioritized energy prices and employment in their choice of preferred energy policy, showing a concern about climate change but with significant variation across groups. Younger respondents had the strongest willingness-to-pay coefficients for CO2 reduction policies, while female respondents, those with more education, those without children, and middle and upper income groups showed stronger desires for CO2 reduction policies.

Summary: The gradual decline in mitochondrial SAM levels leads to defects in mitochondrial function, including loss of metabolites and impaired assembly of the oxidative phosphorylation system. These findings demonstrate the importance of cellular methylation potential for energy metabolism, with direct relevance for pathophysiology, aging, and cancer.

Summary: In this study, X-ray luminous galaxy clusters of low-to-mid redshift selected from the MCXC cluster catalogue were analyzed using XMM-Newton X-ray analysis. The whole sample showed agreement with self-similarity in the Y-X-M-tot and M-gas-M-tot relations. However, relaxed clusters exhibited a flatter relation in several morphology-related relations. Residuals and covariance analysis suggested a positive correlation between M-gas and T, casting doubt on the Y-X parameter as a low-scatter mass proxy. The results also indicated that sample selection based on luminosity biases relations involving M-tot.

Summary: By using the multisite functionalization strategy, single-atom catalysts can overcome the energy scaling relationships in CO2RR and become excellent catalysts. Through extensive first-principles calculations, we discovered two single-atom catalysts (Rh and Ir) embedded in two-dimensional Mo2B2 that can produce methane and methanol with ultralow overpotentials of -0.32 and -0.27 V, respectively.

Summary: This paper presents an X-ray analysis of SDSSRM clusters using data from the XCS. The analysis includes measurements of X-ray luminosity and temperature for a large sample of clusters. The results show that the scatter in the temperature-richness relation is smaller than that in the luminosity-richness relation. The analysis also indicates that the selection method of the sample affects the scaling relation between luminosity and temperature.

Summary: This study investigates the X-ray properties of galaxy clusters at redshifts greater than 1 using deep follow-up XMM-Newton observations. The research finds that scaling relations at low redshift still hold to some extent at higher redshifts, providing important insights into the formation and evolution of high-redshift galaxy clusters.
