Miniaturization and flexibility are becoming the trend in the development of electronic products. These key features are driving new methods in the manufacturing of such products. Printed electronics technology is a novel additive manufacturing technique that uses active inks to print onto a diverse set of substrates, realizing large-area, low-cost, flexible and green manufacturing of electronic products. These advantageous properties make it extremely compatible with flexible electronics fabrication and extend as far as offering revolutionary methods in the production of flexible electronic devices. In this paper, the details of a printing process system are introduced, including the materials that can be employed as inks, common substrates, and the most recently reported printing strategies. An assessment of future setbacks and developments of printed flexible electronics is also presented.

This research explores the transformative impact of automation and advanced control systems on the cheese production line of Ecolácteos Mantaro, aiming to revolutionize operational efficiency and uphold superior quality standards. A detailed diagnostic revealed inefficiencies and safety risks tied to manual operations and outdated technology. Leveraging the process Operations Diagram (POD) and process Activity Diagram (PAD), a comprehensive mapping of the production flow was conducted, emphasizing critical stages such as transportation, inspection, and storage. Root cause analysis through the Ishikawa Diagram pinpointed areas ripe for innovation. The proposed solution introduces cutting-edge automation and a Human-Machine Interface (HMI) system, enabling centralized quality monitoring and real-time decision-making. This innovation ensures rapid operational adjustments, enhances precision, and bolsters safety throughout the process. With an investment of S/. 68,610.00 and a projected payback period of 1 year, 11 months, and 7 days, the initiative is expected to boost cheese production by 58.95%. This leap forward not only amplifies efficiency but also positions Ecolácteos Mantaro as a flexible and market-responsive leader in the dairy industry.

Z production at an e+e- collider, associated with production of other particles, can be an accurate source of information of details of electroweak interactions, including possible interactions beyond the standard model. This is because of the inherent low background at an e+e- collider as well as the fact that the Z state can be fully reconstructed. If the Z decays into a lepton pair, such a final state in spite of the lower branching ratio, can be studied with great accuracy. One such process is e+e-→HZ, where is H is the Higgs boson, the most important process for Higgs production at an e+e- collider. Apart from the angular distribution, the polarization of the Z, fully characterized by its spin density matrix in the productionprocess, can give detailed information about the productionprocess. The vector and tensor polarization parameters of the Z density matrix can be related to angular asymmetries of the decay leptons in the Z rest frame. Thus, an experimental study of these lepton asymmetries can give information on the underlying interactions in Z production. We discuss from a general physical point of view the properties of the density matrix as well as lepton angular asymmetries. While most considerations will be applicable to processes of Z production associated with any other particle or particles, for some discussions, we specialize to a HZ final state. While many of the results can be found in earlier literature, especially for the process e+e-→HZ, we give details of the reasoning, which are not always found. We discuss the properties of the spin density matrix under C, P and T transformations, and combinations thereof, as also the predictions of these for the corresponding leptonic asymmetries. The specific transformations P, CP, T and CPT are of special importance and we discuss the consequences of these symmetries or their absence for the leptonic asymmetries. A specific issue which has been given attention to is the role of beam polarization, and
