Summary: With the increasing awareness of explosion protection due to the global terrorist threat, especially in recent years, explosion protection has become a worldwide issue. People are focusing more on the explosion-proof capabilities of buildings, particularly glass windows. Experimental methods are crucial for evaluating the explosion-proof performance of glass windows, providing valuable data for designing anti-explosion measures.

Summary: Small-molecule organic semiconductors have potential applications in solar cells and medical sensors. However, design rules for improving carrier mobility (mu) are still unclear. This study presents a streamlined simulation workflow, combined with a novel visualization technique, to understand the limitations of mu at the atomic level.

Summary: In their research, Hiroko Tokoro, Shin-ichi Ohkoshi, Eric Collet, and colleagues utilize femtosecond optical spectroscopy and DFT calculations to investigate photomagnetism in RbMnFe material. They identify two photoswitching pathways with different dynamics, where the initial electronic excitation can trigger either the reverse Jahn-Teller distortion or the intervalence Fe-Mn charge transfer.

Summary: Front- and back-junction silicon photovoltaics dominate the market due to lower manufacturing complexity, but achieving efficiency improvements remains challenging. An optimized design by Richter et al. has led to a 26.0%-efficient cell. While interdigitated back-contact cells offer the highest efficiency, both-sides-contacted cells are preferred in industrial production for their simplicity.

Summary: Molecular dynamics simulations play a crucial role in drug discovery, with accurate computations depending on the underlying atomic force field. The CHARMM polarizable force field, based on classical Drude oscillators, offers a rigorous framework to explicitly model induced electronic polarization. Optimal Lennard-Jones parameters in the Drude force field improve accuracy in predicting thermodynamic properties of small druglike organic molecules.

Summary: Sound textures, like running water and buzzing bees, can be synthesized from white noise by imposing statistical features. The perceptual qualities of natural sounds derive directly from these statistical features, and questions are raised about their distribution in the acoustic environment. Analysis of sound textures revealed a great deal of redundancy in texture parameters.

Summary: This paper investigates the importance and prevalence of domain-specific practices in teaching and learning. Different disciplines have their own reasoning practices, referred to as reasoning styles, which are used to justify conclusions. Teach reasoning has proven difficult in practice, especially in subjects where reasoning practices have received limited attention. This paper focuses on reasoning in the curriculum subject of English in primary schools. It suggests that engagement in domain-specific reasoning can be promoted through carefully designed tasks that emphasize collaboration and dialogue. Empirical evidence and theoretical frameworks are used to explore the value of these tasks in promoting reasoning.

Summary: Neural network-based anomaly detection methods have gained attention for their reconstruction ability in hyperspectral remote sensing. A novel probability distribution representation detector (PDRD) is proposed to explore intrinsic distributions of backgrounds and anomalies. Experimental results show the method's accuracy and efficiency compared to state-of-the-art detection methods.

Summary: Case-based design technique is used to analyze the structural efficiency and relationships among umbrella-shaped structure parameters. Differences, characteristics, and applicable scales between different types of umbrella structures are compared. Changes in efficiency under material innovations are explained, and correlations between variables are revealed. The study provides a workable reference for umbrella structure unit design and discusses the practical application of the proposed technique for conceptual design of umbrella structure buildings.

Summary: Compared with traditional axisymmetric charge structure, a novel quadrangular charge structure with preformed fragments on concave surfaces was studied. The velocity distribution and dispersion of fragments in the quadrangular charge structure were determined through a static explosion experiment and pulse X-ray photography. The numerical calculation model of the quadrangular charge structure was verified by comparing it with experimental results, and it was found that the structure had a significant focusing effect on the energy distribution of the preformed fragments. Additionally, the study obtained an empirical formula for the fragment velocity based on the charge structure's concave radians.

Summary: The study developed regression models to predict depth-averaged velocity and critical length using a numerical model, with high accuracy. Geometric parameters, particularly the chute width and longitudinal slope, have significant influences on velocity and critical length, with chute width having a more pronounced impact. The study revealed the dynamic behavior of the structure design under different geometric options.

Summary: The applicability of inhalation therapy is limited by low delivery rates and deposition efficiencies in severe pulmonary conditions. To overcome this, alternative techniques such as intratracheal liquid instillations have been used, but the challenge lies in delivering solutions uniformly across the lungs. This study proposes that foaming the liquid solution prior to instillation can improve pulmonary distribution, as shown in experiments with excised pig lungs.
