    Nowadays, there is great pressure on energy conservation and emission reduction. In order to achieve these goals, weight reduction in manufacturing fields, such as the vehicle, marine, and aerospace industries, and microelectromechanical systems is the major trend. Although some structures and parts that require special properties and service conditions must use ferrous materials such as steels due to their superior thermal and wear resistance, there is a desperate need to replace these alloys with non-ferrous materials such as Al alloys, Mg alloys, Ti-based alloys, Cu alloys, and others in order to decrease the operational and maintenance costs. Recently, many new material processing techniques, i.e., irradiation, cryogenic rolling, wet chemical method, induction sintering, liquid/solid casting, heat treatment, electromagnetic hot forming, and five-axis flank milling, have been developed to enhance the performance of non-ferrous materials. Excellent work hardening, fracture toughness, mechanical properties, magnetic properties, and wear resistance could be realized depending on the appropriate application of these new technologies. This Special Issue covers these topics and focuses on the process-structure-properties relationships of high-performance non-ferrous materials.

    The prostate is the largest accessory gland of the male reproductive tract. Together with seminal vesicles and bulbourethral glands, the prostate is responsible for the production of an alkaline fluid that forms part of the seminal fluid. The prostates of men over 40 years of age are commonly affected by several pathologies, such as benign prostate hyperplasia and cancer.Prostate cancer is one of the most frequently occurring cancers among men population worldwide. According to the World Health Organization (WHO), in the year 2018, prostate cancer affected approximately 1.28 million men and was responsible for the death of 358,989 of them. Prostate cancer development is associated with several risk factors, such as older age, black ethnicity, a family history of disease, an increased body mass index and obesity. In this way, the risk of prostate cancer development may be reduced through the consumption of a healthy diet full of fruits and vegetables, practice of physical exercise and maintenance of a healthy weight.Despite several approaches being available for prostate cancer treatment, the number of prostate cancer deaths is continuously increasing, which emphasizes the need to search for new methods for precocious diagnosis and more effective treatment. Animal models, including rodents, have greatly contributed to the study of biopathology and the prevention and treatment of prostate cancer.This Special Issue presents original research works, case reports and reviews concerning the diagnosis, treatment and prognosis of prostate cancer, highlighting new advances in this field.

    Our era is characterized by two major phenomena. On the one hand, we are confronted by climate and environmental crises constituted by, among others, changing weather patterns, loss of biodiversity and natural wildlife, and ecosystem degradation. On the other hand, we are experiencing an ongoing technological evolution culminating in the rise of artificial intelligence (AI). The popular notion of "AI for Sustainability" constitutes an attempt to connect these two phenomena in a beneficial way by using AI to alleviate climate and environmental worries. AI is increasingly being used in the analysis, mitigation, and prevention of the climate and environmental crises and their effects. Much less attention has been paid to the idea of the "Sustainability of AI", which focusses on the materiality of AI technologies themselves. Indeed, what are the hidden costs of AI? Although we use AI in combatting the climate and environmental crises, does it not have its own contributions to these crises? And, if so, how do we account for these contributions? The Special Issue "Towards the Sustainability of AI; Multi-Disciplinary Approaches to Investigate the Hidden Costs of AI" is the first attempt to address the topic of "Sustainable AI" from a multi-disciplinary perspective. The authors that contributed to this issue come from diverse fields such as philosophy, ethics, sociology, law, and engineering. The included papers represent the first steps in understanding what it means to tackle the climate and environmental crises with AI while refraining from aggravating these crises.
