Abstract The increasing use of composite material require more efficient and inexpensive manufacturing process analysis method to optimize the product quality. The manufacture of textile reinforced composites often requires the preforming of a dry textile reinforcement and the subsequent injection of a resin in Liquid Composite Moulding processes (LCM). The composite can also be produced by thermoforming a prepreg consisting of a textile reinforcement incorporating the unhardened matrix, so that the composite can be formed. In both cases (LCM and prepreg), the forming process is driven by the deformation of the textile reinforcement which is influenced… More >

Abstract In laser powder bed fusion (LPBF), the unmelted powder recovered from the powder bed is degraded due to particle-laser interaction during continuous processing. The sensitivity of LPBF performance and molding quality to powder properties, waste powder is usually discarded after several molding cycles, which increases the cost of raw materials. At the same time, the low laser absorption rate and high thermal conductivity of copper and copper alloys inhibit the complete melting of copper powder prepared by LPBF. Therefore, it is challenging to fabricate copper alloy components with full high density and high conductivity through… More >

Abstract Additively-manufactured microlattice materials have attracted much attention due to their outstanding mechanical properties and energy absorption capacity. Considering the high cost of 3D printing, numerical simulation has become the most common approach for predicting and optimizing the mechanical performance of micro-lattice materials. The current study provides an efficient method to incorporate the printing process induced geometric defects in the lattice models. Numerical simulations are performed to precisely predict the mechanical response of the printed microlattice materials under quasi-static and dynamic loadings. Furthermore, the microlattice structures are graphically represented based on their mesoscopic structural characteristics. Accordingly, More >

Abstract Background: Hypertrophic scars and keloids, common complications following median sternotomy for cardiac surgery, significantly impact patient quality of life due to their aesthetic and symptomatic burden. Recent advancements in laser therapy have made it a prominent option for managing these complex scars, yet a comprehensive understanding of its efficacy is lacking. The aim of this scoping review is to explore the effects of laser therapy in managing hypertrophic scars and keloids after median sternotomy. Methods: This scoping review analyzed studies up to February 2024 from databases including PubMed, EMBASE, CINAHL, Scopus, Web of Science, and… More >

Abstract In the digital information age, distributed file storage technologies like the InterPlanetary File System (IPFS) have gained considerable traction as a means of storing and disseminating media content. Despite the advantages of decentralized storage, the proliferation of decentralized technologies has highlighted the need to address the issue of file ownership. The aim of this paper is to address the critical issues of source verification and digital copyright protection for IPFS image files. To this end, an innovative approach is proposed that integrates blockchain, digital signature, and blind watermarking. Blockchain technology functions as a decentralized and… More >

Abstract Cancer poses a significant threat due to its aggressive nature, potential for widespread metastasis, and inherent heterogeneity, which often leads to resistance to chemotherapy. Lung cancer ranks among the most prevalent forms of cancer worldwide, affecting individuals of all genders. Timely and accurate lung cancer detection is critical for improving cancer patients’ treatment outcomes and survival rates. Screening examinations for lung cancer detection, however, frequently fall short of detecting small polyps and cancers. To address these limitations, computer-aided techniques for lung cancer detection prove to be invaluable resources for both healthcare practitioners and patients alike.… More >

Abstract In the topology optimization of the multiscale structure, ensuring connectivity between adjacent microstructures, controlling the design space of microstructures, and reducing calculation amount and improving calculation efficiency are three basic challenging issues currently faced. To address this, this paper presents a data-driven approach for the integrated optimization of macroscopic topology and microscopic configuration of graded functional cellular structures. At the macro level, a topological description function is introduced to realize the topological control of the macro structure. At the micro level, several cutting functions are used to realize the control of the configuration and size… More >

Abstract 1 General introduction
The flash smelting is one of the dominant technologies for copper matte production. To meet the increasing demand, the production capability of flash smelting furnace has been increased several times. However, under current conditions, the segregation of concentrate particles becomes an escalating issue, impacting production efficiency and safety [1]. The DEM modelling is a powerful tool for investigating particle behaviors such as contact and collision, but the lack of accurate microscopic properties of copper concentrate particles makes it challenging to conduct reliable DEM simulations [2]. To address this gap, this study employs both… More >

Abstract With the everlasting pursuit for weight reduction, efforts are devoted to applying additively manufactured (AM) structures in aeronautic vehicles; however, anomalous fatigue crack growth (FCG) behaviors, such as deflection and branching, are recently observed in macroscale, which deviates from the predictions by classic fracture mechanics. In this work, FCG behaviors of direct energy deposited (DED) Ti–5Al–5Mo–5V–1Cr–1Fe (TC18 in China) are investigated, in which fatigue crack deflections induced by combined impacts of loading and microstructures are revealed. Experiment results show that cracks are more deflected in columnar grains due to the preferred distribution of acicular a… More >

Abstract Contact line pinning and the corresponding contact angle hysteresis (CAH) are important interfacial phenomena that occur in nature and play a significant role in many industrial processes, such as surface coating, ink-jet printing, and immersion lithography. Traditional optical methods face limitations due to the optical diffraction limit, making it difficult to directly measure flow and interface phenomena at the micro- or nanoscale. However, atomic force microscopy (AFM) offers a solution by enabling precise manipulation and force measurements at micro and nano scales. The AFM-based microrheometer, which is assembled with a long-needle probe, can be used More >
