Abstract Modal parameters can accurately characterize the structural dynamic properties and assess the physical state of the structure. Therefore, it is particularly significant to identify the structural modal parameters according to the monitoring data information in the structural health monitoring (SHM) system, so as to provide a scientific basis for structural damage identification and dynamic model modification. In view of this, this paper reviews methods for identifying structural modal parameters under environmental excitation and briefly describes how to identify structural damages based on the derived modal parameters. The paper primarily introduces data-driven modal parameter recognition methods… More >

Abstract The concrete panel of earth-rock dams in cold regions tends to crack due to the combination effect of non-uniform foundation settlement, ice expansion loads, and freeze-thaw damage. In this work, simulations are designed to investigate the effects of freeze-thaw damage degrees on the fracture behavior caused by the partial detachment and ice expansion loads on concrete panels. Results show that the range of detached panels and freeze-thaw damage degree are the dominant factors that affect the overall load-bearing capacity of the panel and the failure cracking modes, whereas the panel slope is a secondary factor.

Abstract Sintering is a pivotal technology for processing ceramic and metallic powders into solid objects. A profound understanding of microstructure evolution during sintering is essential for manufacturing products with tailored properties. While various phase-field models have been proposed to simulate microstructure evolution in solid-state sintering, correctly incorporating the densification assumption—where particles move toward each other by rigid body motion—remains a challenge. The fundamental obstacle lies in the ad hoc treatment of particle motion, where the thermodynamical driving force cannot be derived from the system's free energy. In this work, we present a novel phase-field micromechanics model More >

Abstract With the ever-growing demand for miniature electronics and portable devices, the need for new types of micro-sized, low-cost and high-performance electrochemical energy storage devices becomes a cutting-edge research frontier. Advanced manufacturing technology (such as 3D printing) has brought broad application prospects and new opportunities to the construction of advanced electrochemical energy storage materials and devices. With a focus on “advanced manufacturing of new energy storage materials and devices”, we carried out interdisciplinary research on 3D/4D printing of wearable miniature batteries and supercapacitors, integrable energy devices and systems. Notably, a universal 3D printing approach towards advanced More >

Abstract Zirconium alloys have high strength, high corrosion resistance and low neutron absorption cross section, widely served as the nuclear cladding tubes or some other structural components. During the storage stage of spent fuels or in the lower-temperature reactor-core locations, the hydrogen atoms within the zirconium alloy components would diffuse to the crack tip owing to stress concentration, possibly initiating delayed hydride cracking (DHC) and posing a potential threat to nuclear safety. In this study, the CDM (continuum damage mechanics)-based multi-field coupling computational models are developed, with the hydride-induced hardening and embrittlement, hydride orientation contributions and… More >

Abstract Background: Lung cancer, one of the most prevalent and deadly malignancies worldwide, not only poses a significant physical burden but also a profound psychological challenge to patients. Among these psychological challenges, the fear of recurrence stands out as a particularly distressing issue. This fear, often rooted in the patients’ past experiences with the disease and its treatment, can significantly impact their quality of life, mental health, and even compliance with follow-up care. Moreover, this fear can be exacerbated by the lack of understanding and support from healthcare professionals and family members, further isolating patients and… More >

Abstract Objective: To evaluate the attitudes and practices of oncosexology in the management of breast and prostate cancer in Côte d’Ivoire. Methods: A cross-sectional, multicenter, descriptive and analytical survey carried out over 02 months from 1 November to 31 December 2022, among doctors involved in the management of breast and prostate cancer in Côte d’Ivoire. Results: 78 physicians on 114 participated in the study, with a participation rate of 79.5%. Only one doctor discussed the sexual risks associated with cancer with all his patients and 7.7% of doctors said they never broached questions of sexuality with their… More >

Abstract Arrière-plan: L’information sur la possibilité de rédiger des Directives Anticipées (DA) est une nécessité et représente un enjeu majeur sur les plans médical, éthique, légal. Les difficultés sont nombreuses, organisationnelles ou culturelles, et c’est aussi vrai dans l’univers de la cancérologie, où les DA (et plus largement les discussions anticipées) revêtent une importance cruciale. Sujet éminemment sensible, l’abord des DA (donc d’une réflexion sur la fin de vie) nécessite un travail d’acculturation à la fois sociétale et médico-soignante. Une démarche institutionnelle a donc été élaborée, dans l’objectif d’un déploiement d’outils d’information, de formation des professionnels,… More >

Abstract 3D concrete printing (3DCP) has challenges in weak interlayer bond strength and steel reinforcement integration. Existing methods to improve the interlayer bond strength and integrate steel reinforcement have limitations in automatic operation and limited mechanical performance improvement. Strain hardening cementitious composites (SHCC), with the high tensile strength and tensile strain capacity, have the potential to achieve self-reinforced structures in 3DCP. Nevertheless, the wider adoption of SHCC in 3DCP is limited by the high cost of fibers and fiber agglomeration during printing.
To fill the gap, this study investigates the use of SHCC as bonding agent of… More >

Abstract Arthritis, caused by degeneration and wear of articular cartilage, affects millions of patients worldwide. It can result in chronic pain, swelling, stiffness, and significantly affect the mobility of patients. Hence, identifying a material as an artificial alternative to replace damaged cartilage is of great benefit. Hydrogel, because of its high water content and similarity with the extracellular matrix of cartilage, has been explored for potential use as artificial cartilage. In this investigation, Polyvinyl Alcohol-Polyethylene Oxide (PVA/PEG) hydrogel with similar mechanical properties to human articular cartilage (e.g. compressive modulus, stress-strain response) was fabricated using a freeze-thaw… More >
