Biomanufacturing has gained significant importance in recent years due to its role in developing new medications, handling pandemics, and increasing the well-being of human populations. The nature of biochemical processes requires complex planning and control, with many controlled and non-controllable variables that impact the quality of bioproducts. Representing biomanufacturing process knowledge, control models, and actual occurrences in coherent ontologies could aid both humans and computers in dealing with the complexity. However, there is a lack of such coherent ontologies. Even though the Industrial Ontology Foundry (IOF) Core ontology has provided a groundwork based on the widely used Basic Formal Ontology (BFO) for such ontological requirements, there are still insufficient constructs and clear guidance on the representation of digital artifacts and their correspondences to the physical counterparts. This paper presents a framework to extend the IOF Core to address the gap. The framework is founded on establishing a counterpart (CR) relation pattern presented in our previous paper. Counterpart relation was selected for its ability to facilitate a more intuitive and concise representation of many kinds of digital artifacts (e.g., planned, designed) and physical entities (e.g., planning process, manufacturing process). We validated the approach with a process verification of a fed-batch bioreactor operation. The paper started by defining the use case requirement, which was followed by an ontology development. A knowledge graph of the bioprocess plan and occurrences of processes in the plan was then instantiated. Competency questions were used to concretize the ontology requirement from the use case, and subsequently, an executable set of queries was created from them and was used to computationally validate the ontology against the requirement. The GraphDB tool was used to support the validation. The result of this research not only showed that the CR pattern

Many studies have been performed on integrating the Internet of Things (IoT) with cloud services. As these systems become widely used, quality metrics are of concern. For example, users might specify access control to restrict their sensitive data being processed in the cloud. Routers, e.g., API gateways, message brokers, or sidecars, can provide this access control by blocking or routing device data to a specific cloud service. However, a static routing application might not suit the dynamic behavior of IoT applications well. For example, in a centralized schema, where all device data is routed to a component for control checking, performance can be an issue. On the other hand, distributed routing can harm the reliability of a system, as device data might be lost due to an unresponsive service. We present the Smart and Adaptive Routing (SAR) architecture that creates an optimal reconfiguration solution using a deep neural network based on the quality metrics of an IoT application. To design our architecture, we give a background of the published studies and a review of the gray literature, e.g., practitioner blogs, to categorize the knowledge in the domain of IoT-cloud traffic management. We systematically evaluate our approach in an extensive evaluation of 4500 cases and compare SAR with an empirical data set of 1200 hours. The results show that our approach significantly improves quality-of-service measures by adapting the IoT-cloud system at runtime.

In this paper, we propose a lattice-based certificateless signature scheme and certificateless aggregate signature which can be used to verify a large number of signatures simultaneously efficiently. To improve the security of our scheme, we have implemented our signature algorithm without trusted third parties. The security of our proposed signature algorithm can be reduced to the SIS problem under the random oracle model. Moreover, our construction only needs matrix multiplication and rejection sampling operation, so the algorithm is naturally simple and efficient. Besides, we've done some experiments using the NTL library, indicating our scheme has less time overhead and storage overhead than other schemes. To our best knowledge, we propose the first certificateless aggregate signature without trapdoors.

Graph stream data is widely applied to describe the relationships in networks such as social networks, computer networks and hyperlink networks. Due to the large volume and high dynamicity of graph streams, several graph sketches were proposed to summarize them for fast queries. However, the existing graph sketches suffer from low performance on graph query tasks due to hash collisions between heavy and light edges. In this paper, we propose a novel learning-based Dichotomy Graph Sketch (DGS) mechanism, which adopts two separate graph sketches, a heavy sketch and a light sketch, to store heavy edges and light edges respectively. DGS periodically obtains heavy edges and light edges in a session of a graph stream, and use them as training samples to train a deep neural network (DNN) based binary classifier. The DNN-based classifier is then utilized to decide whether the upcoming edges are heavy or not, and store them in different graph sketches accordingly. With the learnable classifier and the dichotomy graph sketches, the proposed mechanism can resolve the hashing collision problem and significantly improve the accuracy for graph query tasks. We conducted extensive experiments on three real-world graph stream datasets, which show that DGS outperforms the state-of-the-art graph sketches in a variety of graph query tasks.

In the framework of STILES PNRR Project and as a natural evolution of the INAF Minigrant project on the Integrated approach to the mechanical design for Astronomical Instrumentation, an advanced mechanical engineering laboratory inside the INAF - Observatory of Naples was funded. This facility represents a leap forward in technological research applied to design and development of Ground-based Telescope Instrumentation for the researchers who will use these innovative technologies. The role of the new laboratory for mechanical engineering, in the INAF context, is essentially to support the advanced design, develop prototypes with different Additive Manufacturing 3D printers, maintain state-of-the-art for astronomical instruments and equipment and revamp/retrofit the existent facilities utilizing also the Reverse engineering approach. The real innovation of this laboratory is represented by the technologies and techniques that will be implemented inside of it. Another focus is on Metrology applied to characterize, control and accept the mechanical items designed with 3D CAD software and validated by FEA approach during the design phase. The synergy between these disciplines promises to improve the scientific collaboration and the technological expertise for INAF researchers of Naples. Mechanical engineering is the backbone of the astronomical facilities, always bigger than previous one, and enable astronomers to make groundbreaking discoveries and expand our knowledge of space.
