“…Data collection and processing (D1) assesses if an enterprise gathers comprehensive and real-time data and if the data it obtains are the most representative [42]. Data analytics capability (D2) gauges whether the enterprise comprehensively and logically interprets the collected data, ensures accurate data comprehension, and effectively mines information from the data [43]. Data security (D3) signifies the enterprise's measures to safeguard data securely and in compliance with the law, including continuous security maintenance, which covers the security of both data sources and data protection [44].…”

With digital transformation underway in various Chinese construction enterprises, each enterprise has progressed differently, and a clear direction for future digital transformation and upgrading is lacking. As such, the importance of measuring the level of digitization among Chinese construction enterprises is increasing. This paper presents a model for evaluating digital transformation maturity within construction enterprises. The model considers six aspects: digital strategy, digital business applications, digital technology capabilities, and so on. The digital maturity of enterprises is determined using the Analysis of Hierarchy (AHP)-Decision Making Experiment and Evaluation Laboratory (DEMATEL) method. Technical abbreviations are explained when first used. This study demonstrates that digital business applications are the most significant primary indicator, with a weight of 29.53%. The success of digital transformation in the construction industry is strongly influenced by the interconnection between digital technology and construction sites, as well as other factors such as new technical personnel, digital infrastructure, digital innovation, and innovation iteration ability. It is crucial to understand how digital technology and the construction industry can effectively connect in order to achieve success in this realm. This paper aims to enhance the digital transformation capabilities and efficiency of construction companies and boost their core competitiveness through targeted measures.

“…In perpendicular magnetic recording, the existence of Bloch wall in a soft magnetic underlayer causes the appearance of an out-of-plane stray field. This feature can leads to an additional noise signal during information reading 2 3 . In microwave assisted magnetic recording, the magnetization of a field generation layer inside a spin torque oscillator needs to be strictly aligned in the plane to stabilize magnetic rotation in the field generation layer 4 .…”

This study investigated the magnetic domain walls in a single-layer soft magnetic film with strong magnetocrystalline anisotropy energy. The soft magnetic film is composed of a highly c-axis-oriented hcp-Co81Ir19 alloy with strong negative magnetocrystalline anisotropy. The domain structure of the soft Co81Ir19 films with thickness ranging from 50–230 nm in a demagnetization state was observed through magnetic force microscopy and Lorentz transmission electron microscopy. Results reveal that the critical transition thickness at which the domain wall changes from Néel type to Bloch type is about 138 nm, which is much larger than the critical value of traditional Fe- and Co-based soft magnetic films with negligible magnetocrystalline anisotropy. Theoretical calculation was also performed and the calculated result agrees well with experimental data.
