Summary: Previous studies mainly focused on the temporal analysis of thermal infrared radiation variations for rocks under loading conditions, while quantitative studies on the spatial features caused by stress variations and fracture activity were scarce. In this study, the standard deviational ellipse algorithm was introduced for spatial statistical analysis based on temporal analysis. The ellipse parameters can quantitatively describe the evolution trend of the infrared radiation temperature field on the rock surface and indicate the macrofracture location.

Summary: The development of green residences is crucial for reducing energy consumption and carbon emissions in the construction industry. However, there has been insufficient attention given to the spatial distribution characteristics and influencing factors of green residences in the academic circles. This paper uses panel data from 2008 to 2016 to analyze the spatial and temporal evolution features of green residences in China and identifies the driving mechanisms and key factors from various aspects. The findings indicate that China has a stable and clear evolution path for green residences, mainly in the central and eastern regions, and the development is influenced by multiple factors.

Summary: This study quantitatively evaluated the impact of anthropogenic nitrogen emissions on the water environment in the Yangtze River Delta city cluster and analyzed the spatiotemporal characteristics of the grey water footprint (GWF) and the relative contributions of natural and human factors to water pollution levels (WPL). The results showed a decrease in anthropogenic nitrogen emissions from 2011 to 2020, driven by reduced fertilizer application and livestock numbers. Non-point sources were found to dominate the GWF, and high and low GWF were concentrated in the northeast and southwest regions, respectively. The study also identified variations in WPL due to precipitation and proposed measures to decrease nitrogen emissions.

Summary: We propose a new class of Lipschitz operators, called lattice Lipschitz maps, defined on Euclidean lattices. We show that the extension results obtained from the McShane and Whitney formulas for real valued functions can also be applied to lattice Lipschitz maps. Our main result demonstrates the equivalence between being a lattice Lipschitz map in Euclidean space and having a diagonal representation with real-valued Lipschitz functions as coordinate coefficients. We also establish the connection between the extension of a diagonalizable operator and the operator obtained from the McShane and Whitney formulas in the linear case. This work contributes to the development of machine learning algorithms based on Lipschitz function extension.

Summary: With the rapid economic development and urbanization in China, the expansion of urban space and the growing demand for land have led to the destruction and expropriation of ecological land. Therefore, studying China's territorial ecological space and its evolution rules is important. This study establishes a classification system for ecological space and analyzes the pattern and migration of various ecological spaces in China. The results show that China's territorial ecological space is relatively stable but unevenly distributed. Thus, implementing differentiated policies to optimize and control territorial ecological space is necessary, along with establishing a unified and coordinated territorial space management and control system.

Summary: This article studies a scenario that derives four-dimensional modular flavor symmetric models from a higher-dimensional theory, assuming a compactification consistent with the modular symmetry. The wave functions in the extra-dimensional compact space are modular forms, which impose constraints on combinations between modular weights and Gamma(N) (Gamma '(N)) representations of matter fields. Illustrating examples are also presented.

Summary: This study presents new results on classical-particle propagation under Lorentz violation, focusing on spin-nondegenerate operators provided by the fermion sector with arbitrary mass dimension. The obtained classical Lagrangians for the operators (b) over cap (mu) and (H) over cap (mu) as perturbative expansions in Lorentz violation reveal peculiar functional dependence in background fields, possibly due to the essential role of particle spin. These Lagrangians will be valuable for describing particle propagation in curved backgrounds with diffeomorphism invariance and/or explicitly violated local Lorentz symmetry.

Summary: The paper proposes a methodology for deriving a reduced-order model from a complex n-dimensional system. A mathematical model for a voltage-lift-based quadratic high-gain dc-dc converter is proposed with a reduced-order model in continuous conduction mode. The chosen topology combines voltage-lift cells with a quadratic boost topology to improve voltage gain. The paper discusses the operating principle, state-space averaging procedure, pole clustering method, and Ziegler-Nicholas tuning technique for designing a suitable controller and evaluating the converter's performance.

Summary: This paper discusses the enfolding of N-dimensional Euclidean space through N-dimensional spheres, constructing a framework associated with time. By using Euclidean norms and modules of vectors to represent time-like spheres, particles, objects, and even the Universe can be connected to time-like spheres. This allows for a description of the relationship between particles, objects, and the Universe with time foam in 3-dimensional Euclidean space.

Summary: In this paper, we classify Ricci solitons on pseudo-Riemannian hypersurfaces of a Minkowski space E-1(4) by considering the potential vector field as the tangent component of the position vector. We obtain the necessary and sufficient condition for the existence of such Ricci solitons and provide characterization results for different types of pseudo-Riemannian hypersurfaces.

Summary: This study examines the effects of CP violation on the electroweak phase transition in the standard model, focusing on a scenario where additional scalars have masses close to 125 GeV. The high mass degeneracy in this scenario makes it difficult to distinguish collider signatures from the standard model predictions. Simplified scalar potential and one-loop effective potential with thermal resummation are used for qualitative and numerical evaluations. It is found that as CP violation increases, the strength of the first-order electroweak phase transition weakens and gravitational wave amplitudes are diminished. Future gravitational wave experiments may provide insights into CP violation in the singlet scalar sector and the experimental blind spot caused by the high mass degeneracy.

Summary: This study compares the application of modified microbial flocculants (MMFs) with conventional organic flocculants in mitigating membrane fouling. The results show that MMF has better performance in pollutant removal and membrane fouling control. The study also reveals that cake layer formation is the main mechanism of membrane fouling and MMF can reduce the accumulation of foulants on the membrane surface. Correlation analysis indicates that total phosphorus, polysaccharide, zeta potential, and particle size have the greatest correlation with fouling resistance.

Summary: In this article, a sparse alternating iterative minimization (SAIM) method is proposed to address the direction-of-arrival (DOA) estimation problem via a non-ideal acoustic vector hydrophone (AVH) array. The method establishes a non-ideal AVH array model and formulates a new cost function to provide accurate DOA estimation. Extensive numerical simulation and experimental results demonstrate the superior DOA estimation performance of the proposed method.

Summary: This study aims to investigate the dynamic response associated with the impact of a kinetic projectile on the internal structure of an artificial satellite. Through ground damage testing and finite element dynamic simulation, we determined the lateral effect and penetration performance of the projectile, and studied its dynamic behavior when penetrating a honeycomb sandwich panel and multi-layer plates. The ballistic limit velocity of the projectile was found to be 150 m/s, and the deformation of the opening had little relationship with the projectile velocity. Additionally, it was observed that the launch velocity required to meet the damage requirements of the multi-layer plates was within 325 +/- 25 m/s, with higher initial velocities resulting in reduced damage area.

Summary: This article proposes a two-branch generative adversarial network with multiscale connections (TBGAN) to address the limited-labeled and class-imbalanced datasets in hyperspectral image classification. TBGAN uses two generators to produce spectral and spatial samples and places multiscale connections between the discriminator and generators to alleviate instability problems. Experimental results show that TBGAN achieves competitive classification accuracy and has lower sensitivity to training sample size compared to state-of-the-art methods.

Summary: This research examines the impact of Buddhism on mergers & acquisitions (M&As) performance using data from 4622 M&A transactions of Chinese public firms between 2004 and 2018. The findings provide ample evidence that acquirers located in regions with a higher intensity of Buddhism achieve better short-term and long-term performance after the merger. Furthermore, the study reveals that state ownership plays a crucial role in mitigating this effect, and the value creation is driven by higher deal completion rates and fewer violation cases for acquiring firms. Finally, the study addresses the issue of endogeneity, and the results remain unchanged.
