In this work, a novel approach to realize a plasmonic sensor is presented. The proposed optical sensor device is designed, manufactured, and experimentally tested. Two photo-curable resins are used to 3D print a surface plasmon resonance (SPR) sensor. Both numerical and experimental analyses are presented in the paper. The numerical and experimental results confirm that the 3D printed SPR sensor presents performances, in term of figure of merit (FOM), very similar to other SPR sensors made using plastic optical fibers (POFs). For the 3D printed sensor, the measured FOM is 13.6 versus 13.4 for the SPR-POF configuration. The cost analysis shows that the 3D printed SPR sensor can be manufactured at low cost (∼15 €) that is competitive with traditional sensors. The approach presented here allows to realize an innovative SPR sensor showing low-cost, 3D-printing manufacturing free design and the feasibility to be integrated with other optical devices on the same plastic planar support, thus opening undisclosed future for the optical sensor systems.

Introduction: While stroke remains a leading cause of death and disability, recent advances in endovascular technology an important opportunity to make a significant impact in clinical outcomes. However, training opportunities are rare, preventing dissemination of these techniques. Hands-on training is further complicated by the critical time to therapy associated with stroke treatment. This physical simulator was built for neurosurgical residents and fellows to practice mechanical thrombectomy. Methods: A simplified virtual model of the anterior cerebral circulation was created based on patient imaging. This luminal model was 3D printed using flexible filament and attached to a guide catheter at the proximal carotid to provide endovascular access and an IV tube at the distal M2 branches to permit outflow. A 7Fr sheath was also connected at the anterior cerebral artery to permit placement of a simulated clot model and simulate a proximal M1 occlusion. This entire construct was placed into a container of polyvinyl alcohol (PVA) and after crosslinking the flexible print was removed. Results: Using 3D printing technology and polymer hydrogels, a low-cost, high fidelity stroke model was achieved. Despite its simplified anatomy, the model permitted realistic wire and catheter navigation through the different segments of the internal carotid and middle cerebral arteries. The ACOM sheath provided a convenient method to reliably place an embolism and created a life-like proximal M1 occlusion. Recanalization was performed using the solumbra technique, which is used in live-patient cases. Conclusions: This model demonstrated proof of concept for a mechanical thrombectomy simulation. The angiographic profile and response to endovascular tools created a training experience similar to live endovascular procedures. As the model is perfected visually and mechanically, next steps are to perform validation studies and create a training curriculum.

Abstract: Operational HR encompasses the highly visible, day-to-day tactical operations required to keep a workforce running. This made us look for strategic approaches essential for most organisations. Be it defining the future path, determining the future plan, mission, vision, planning, objectives and goals of a particular organization. In a nutshell, we wanted to bring out the intricate relationship between HR and operational research especially considering the current dynamics of the external world. The unprecedented changes in HRM made us dig deeper on the importance of the role and applications of operations research to cope with these changes. Finally, we believed our research was complete when we presented real-world examples, and it was demonstrated to us that Operations Research approaches may assist firms in making good HR policy decisions at a low cost

In recent decades, 3D acquisition by laser scanning or digital photogrammetry has become one of the standard methods of documenting cultural heritage, because it permits one to analyze the shape, geometry, and location of any artefact without necessarily coming into contact with it. The recording of three-dimensional metrical data of an asset allows one to preserve and monitor, but also to understand and explain the history and cultural heritage shared. In essence, it constitutes a digital archive of the state of an artefact, which can be used for various purposes, be remodeled, or kept safely stored. With the introduction of 3D printing, digital data can once again take on material form and become physical objects from the corresponding mathematical models in a relatively short time and often at low cost. This possibility has led to a different consideration of the concept of virtual data, no longer necessarily linked to simple visual fruition. The importance of creating high-resolution physical copies has been reassessed in light of different types of events that increasingly threaten the protection of cultural heritage. The aim of this research is to analyze the critical issues in the production process of the replicas, focusing on potential problems in data acquisition and processing and on the accuracy of the resulting 3D printing. The metric precision of the printed model with 3D technology are fundamental for everything concerning geomatics and must be related to the same characteristics of the digital model obtained through the survey analysis.
