An important part of the accessibility of the urban environment is the connectivity of transport network, especially regarding to its usage via personal transport. There are many methods of quantitative analysis of this aspect. A significant part of them is based on the isochronal analysis. The article assumes that on the local scale the one of the key factors indicating a transport network connectivity is the asymmetry between forward and backward routes between pairs of points. A method of such analysis, the computational experiment, and the following statistical analysis procedure for checking this hypothesis. Performing this procedure allows us to confirm the hypothesis with statistical significance p=*** experiment presented in the article demonstrates the need to take into account the path asymmetry factor for calculating and evaluating transport accessibility. The given method can be used in optimizing public transport routes, designing traffic flows, and planning the development of the territory in urban agglomerations.

End-of-life vehicles (ELVs) present both opportunities and challenges for resource conservation and environmental protection. However, China's uncontrolled and disorderly expansion of the recycling industry has resulted in a mismatch between recycling capacity and demand (including overcapacity and undercapacity), with negative impacts such as resource waste and environmental pollution. Analyzing spatio-temporal patterns and evaluating the recycling capacity matching is essential to promote sustainable development. However, previous studies focused narrowly on national/provincial-scale patterns of ELVs or ignored the issue of recovery capacity matching (especially overcapacity), which does not meet the needs of policy development at the city scale and the reality of recycling management in China. Therefore, this study simulated the end-of-life internal combustion engine vehicles (ICEVs) and new energy vehicles (NEVs) in Chinese cities from 2021 to 2050, revealing the city-scale spatio-temporal patterns and urban differences regarding perspectives of development levels and geographical locations. More importantly, this study quantitatively evaluates the matching relationship between existing recycling systems and projected future demand at city-scale. Warnings and suggestions are provided for cities with severe matching problems. The results indicate that the number of ELVs in China will continue to increase, peaking at 3.5-3.7 million, approximately seven times higher than in 2020, mainly driven by third to fifth-tier cities. ELVs will gradually be concentrated in central and southwestern cities, accounting for 47% of NEVs and 50% of ICEVs. Most cities have excess dismantling capacity, while first-tier cities face incoordination problems in battery collection. Spatial coordination across cities or provinces is prioritized for dismantling enterprises over blind deregistration or establishment. Effective solutions to the battery collection incoordination should requir

Evaluating multi-center molecular integrals with Cartesian Gaussian-type basis sets has been a long-standing bottleneck in electronic structure theory calculation for solids and molecules. We have developed a vector-coupling and vector-uncoupling scheme to solve molecular Coulomb integrals with solid harmonics basis functions(SHGO). Solid harmonics are eigenstates of angular momentum, making it possible to factorize molecular integrals. By combining solid harmonic addition, differential and product rules, the computationally costly multi-center four-center integrals can be factored into an angular part and a radial component dependent on the atomic positions. The potential speed-up ratio in evaluating molecular nuclear Coulomb integrals in our method can reach up to four orders of magnitude for atomic orbitals with high angular momentum quantum numbers. The foundation underpinning the mathematical efficiency is the quantum angular momentum theory, where both vector-coupling and vector-uncoupling schemes correspond to unitary Clebsch-Gordan transformations that act on quantum angular momentum states, influencing their degree of entanglement. By incorporating quantum angular momentum through these transformations, the entanglement of the states can be reduced, and the less entanglement there is for a quantum system, the easier it is to simulate. The highly efficient method unveiled here opens new avenues for accelerated material and molecule design and discovery. © 2024, CC BY-NC-SA.

The 'Internet of things' is the developing technology to transfer the world into smart innovation. 'IoT' security is the most problematic issue in recent applications due to its properties including 'centralized architecture', 'limited capacity devices', and 'ambiguity'. So, blockchain with 'IoT' applications provides secure data communication compared to traditional 'IoT' applications. Blockchain is a recent growing technology that has features including 'decentralized structure', 'transparency', 'immutable records', 'increased capacity', and 'quick backtracks'. The 'cryptography hash algorithm' is very important to provide secure data transmission. It converted the different size input to fixed-size unalterable output to enhance the security. But still, it needs efficient algorithm to secure data transmission with safeguard of private key. The objective of this paper is to propose a secure hash cryptography algorithm with double encryption (SHCA-DE) to protect the private key message. Then, this proposed algorithm has been analyzed with MD5, SHA-256, and SHA3-512. From this analysis, the SHA3-512 performs well with proposed algorithm. © 2024 IEEE.

Real-time Anomaly Detection is of great importance in industrial applications in order to have high-quality production and avoid downtime or failure of the system. In this paper, we study the application of anomaly detection over the multivariate data collected from Glass Production Industry. Our experiments utilize and compare different Unsupervised multivariate time series Anomaly Detection and Localization algorithms that have already demonstrated significant results on the state-of-the-art data sets. We propose a two-level multivariate anomaly detection approach that not only detects anomalous events in the production line but also categorize the different type of anomalies based on statistical pattern recognition. Furthermore, we localize the anomalous sensors by utilizing Explainable-AI approaches to help better decision-making in glass production monitoring. In this work, we propose an efficient pipeline for Anomaly Detection, Categorization and Localization which the experiments show promising results.

Immune checkpoint inhibitors (ICIs) have rejuvenated therapeutic approaches in oncology. Although responses tend to be durable, response rates vary in many cancer types. Thus, the identification and validation of predictive biomarkers is a key clinical priority, the answer to which is likely to lie in the tumour microenvironment (TME). A wealth of data demonstrates the huge impact of the TME on ICI response and resistance. However, these data also reveal the complexity of the TME composition including the spatiotemporal interactions between different cell types and their dynamic changes in response to ICIs. Here, we briefly review some of the modalities that sculpt the TME, in particular the metabolic milieu, hypoxia and the role of cancer-associated fibroblasts. We then discuss recent approaches to dissect the TME with a focus on single-cell RNA sequencing, spatial transcriptomics and spatial proteomics. We also discuss some of the clinically relevant findings these multi-modal analyses have yielded. © 2023 The Author(s)

We developed an anisotropic exchange spin model that accounts for magnetic anisotropy and evaluated the Curie temperature ( T c ) dispersion due to finite-size effects in L1 0 -FePt nanoparticles. In heat-assisted magnetic recording (HAMR) media, a next-generation magnetic recording technology, high-density recording is achieved by locally heating L1 0 -FePt nanoparticles near their T c and rapidly cooling them. However, variations in T c caused by differences in particle size and shape can compromise recording stability and areal density capacity, making the control of T c dispersion critical. In this study, we constructed atomistic Landau-Lifshitz-Gilbert models to explicitly incorporate the spin exchange anisotropy of L 1 0 -FePt, based on parameters determined by first-principles calculations. Using this model, we evaluated the impact of particle size on T c dispersion. As a result, (1) the T c dispersion critical to the performance of HAMR can be reproduced, whereas it was previously underestimated by isotropic models and (2) approximately 70 % of the experimentally observed T c dispersion can be attributed to particle-size effects. This research highlights the role of exchange anisotropy in amplifying finite-size effects and underscores the importance of size control in HAMR media. © 2025 Author(s).
