The article aims at optimizing six-phase induction generator-based renewable energy systems (6-phase IGs or dual star induction generators) through a novel nonlinear optimal control method. Six-phase induction generators appear to be advantageous compared to three-phase synchronous or asynchronous power generators, in terms of fault tolerance and improved power generation rates. The dynamic model of the six-phase induction generator is first written in a nonlinear and multivariable state-space form. It is proven th [...]

This review intended to resume key Research reports and publications that open many themes and topics related to Carbon-based semiconductors and Quantum emitters. The Design and synthesis of highly pure materials such as Graphene, Carbon Nanotubes, fullerenes, and other Carbon-based allotropes were shown. They presented their most important and promising properties concerning new studies and developments in photonics. Carbon-based Quantum dots, semiconductors, and higher sized Nanoplatforms allowed us to discuss fu [...]

The methylation effects on protein-DNA interactions, which can be perceived as a special kind of specificity of transcription factors, have been successfully quantified in the last years by various methods. In this work, I give a summary about the sequence encoding scheme, the underlying additive model about specificity and methylation sensitivity, and the regression strategy to analyze Methyl-Spec-seq data. Then I explain why given the current experimental setup, it is more appropriate to model the methylation eff [...]

The interpretation of aging as an adaptive and programmed phenomenon implies the existence of specific genetically determined and regulated aging-causing mechanisms. This interpretation is in contrast to the explanation of aging as the gradual accumulation of the effects of harmful factors that are only partially countered by natural selection. The subtelomere–telomere theory of aging offers what is required by the interpretation of aging as a programmed phenomenon. The experimentally documented mechanisms that are [...]

Transplant tolerance has been achieved in experimental models using immune intervention strategies. Yet, their clinical translation remains unsuccessful and requires further optimization of immunotherapeutic regimens based on a deeper understanding of the cellular and molecular mechanisms at play in the induction and maintenance phases of immune tolerance. Intensive investigations have shed light on the tolerogenic networks underlying graft survival and have unraveled their complexity, which may depend on several p [...]

China adopted a “Zero-COVID” policy for nearly three years, making Chinese healthcare workers constantly involved in COVID-19-related work. However, little is known about how involvement in COVID-19-related work shaped Chinese nurses’ burnout. This study explores how nurses’ job demands and job resources are associated with their burnout by considering high and low frequent involvements in COVID-19-related work in China. This study employed a cross-sessional design. Guided by Job Demands-Resources (JDR) model, we d [...]

Current production and distribution models in agriculture primarily operate based on the 'linear economy' approach. This means that after the exploitation of natural resources and the production of the final product, a significant portion of these resources and products, now contaminated or turned into waste, exit the economic cycle. The circular economy approach in agriculture seeks to reuse waste products and depleted inputs, thereby reducing the intensity of resource exploitation and taking a step towards sustai [...]

Combining dental ceramics with other prosthetic metallic restorations might release metal ions, thus affecting the oral tissues of the patients. In this study, we evaluated the electrochemical solubility of various dental ceramics in a galvanic experimental setup in vitro. Smooth and rough feldspathic and zirconium dioxide ceramics (at pH 5.5 and pH 3.0) were exposed to an electric field. Calcium, barium, and zirconium were selected as parameters to determine the solubility of both types of ceramic materials. Among [...]

The dinuclear complexes [Co2(CO)6{P(OAr)3}2] (1a, Ar = Ph; 1b, Ar = o-Tol) were prepared and reacted with PhC≡CH and PhC≡CPh to yield dimetallatetrahedranes [{(ArO)3P}(OC)2Co-Co(μ-RC≡CPh)(CO)2{P(OAr)3}] (3a, Ar = Ph, R = H; 3b, Ar = o-Tol, R = H; 3c, Ar = Ph, R = Ph; 3d, Ar = o-Tol, R = Ph). The main reaction of diphenylacetylene was accompanied by a side reaction, leading to the dissociation of a P(OAr)3 ligand for the formation of mono(phosphite) complexes [{(ArO)3P}(OC)2Co-Co(μ-PhC≡CPh)(CO)3] (2b, R = Ph; 2d, R [...]
