Robotized inspection and health monitoring in the Gran Sasso National Laboratory
Rinaldi, Cecilia,Di Sabatino, Umberto,Potenza, Francesco,Gattulli, Vincenzo Techno-Press 2021 Structural monitoring and maintenance Vol.8 No.1
The Gran Sasso National Laboratory (LNGS) is the largest underground research center in the world devoted to neutrino and astroparticle physics. It is located in galleries below about 1400 meters of rock mass. In this environment, inspection and monitoring actions are challenging for the maintenance and the safety of the infrastructures and they require a combined use of different strategies. The paper address issues related to the structural safety of the whole environment by proposing solutions for inspection and monitoring of different areas and elements, such as the gallery vaults, the structures of the experimental prototypes, the plants and the machinery. A generic framework is discussed to evidence the features of each specific solution and the interaction between different systems. Tunnel structural healthy is the most difficult to evaluate because the vaults are coated by not removable panels which waterproof and insulate the environment. Therefore, specific solutions are proposed for the inspection and monitoring of the vaults which are visible only in the interspace realized from such cladding panels. In this respect, different methodologies based on the use of robotic systems are presented and discussed in order to implement a suitable inspection and monitoring program. The complementary requirements to perform a mechatronic survey are defined also as basis of ongoing activities currently performed in LNGS.
Seismic performance evaluation for steel MRF: non linear dynamic and static analyses
Z. Rinaldi,B. Calderoni 국제구조공학회 2002 Steel and Composite Structures, An International J Vol.2 No.2
The performance of steel MRF with rigid connections, proportioned by adopting different capacity design criteria, is evaluated in order to highlight the effectiveness of static non-linear procedure in predicting the structural seismic behavior. In the framework of the performance-based design, some considerations are made on the basis of the results obtained by both dynamic time histories and push-over analyses, particularly with reference to the damage level and the structure ability to withstand a strong earthquake.
Managing liver cirrhotic complications: Overview of esophageal and gastric varices
Cosmas Rinaldi Adithya Lesmana,Monica Raharjo,Rino A. Gani 대한간학회 2020 Clinical and Molecular Hepatology(대한간학회지) Vol.26 No.4
Managing liver cirrhosis in clinical practice is still a challenging problem as its progression is associated with serious complications, such as variceal bleeding that may increase mortality. Portal hypertension (PH) is the main key for the development of liver cirrhosis complications. Portal pressure above 10 mmHg, termed as clinically significant portal hypertension, is associated with formation of varices; meanwhile, portal pressure above 12 mmHg is associated with variceal bleeding. Hepatic vein pressure gradient measurement and esophagogastroduodenoscopy remain the gold standard for assessing portal pressure and detecting varices. Recently, non-invasive methods have been studied for evaluation of portal pressure and varices detection in liver cirrhotic patients. Various guidelines have been published for clinicians’ guidance in the management of esophagogastric varices which aims to prevent development of varices, acute variceal bleeding, and variceal rebleeding. This writing provides a comprehensive review on development of PH and varices in liver cirrhosis patients and its management based on current international guidelines and real experience in Indonesia.

Purpose: In the present study, meningococcal serogroup B outer membrane vesicles (OMVs) were associated with bilayer fragments of a cationic lipid, dioctadecyldimethylammonium (DDA-BF), used as adjuvant, in an antigenic preparation tested in adult female outbred mice. This adjuvant was compared to the traditional adjuvant aluminum hydroxide. Materials and Methods: The potential in generating humoral response was evaluated by enzyme-linked immunosorbent assay (ELISA). Individual serum was collected and immunoglobulin G (IgG), IgG1, IgG2a, and IgG2b were quantified. Analyses were carried out 15 and 60 days after immunization. Antibodies avidity index were also analyzed by ELISA. Immunoblot and dot-ELISA were carried out to evaluate specific reaction for homologous strains and cross-reactive antigens present in other meningococcal strains isolated in 2011–2012 year, in Brazil. Delayed type hypersensitivity was used as indicative of cellular immunity and compared between two experimental groups, 24 hours after homologous strain challenge. Results: The OMVs of Neisseria meningitidis, and N. lactamica (related species) were characterized by electrophoretic separation of proteins in 13% polyacrylamide gel. The strains presented antigens in the range of 8 to 130 kDa, showing a heterogeneous protein migration pattern. In the group immunized with OMVs/DDA-BF, we found no significant production of total IgG 15 days after the first immunization. On the other hand, 60 days after first immunization both adjuvants act benefiting total IgG production similarly. The antibodies of the IgG isotype produced by animals immunized after one or two doses after first immunization, showed intermediate and high avidity, independent on the adjuvant used. In both experimental groups the swelling of the footpads was significantly higher than those of the controls, suggesting that only one dose was enough to stimulate the generation of cellular immunity. Conclusion: The use of this cationic adjuvant for N. meningitidis OMVs preparation revealed good potential for future new antigen preparation for N. meningitidis vaccine.
Transnational Social Capital and FDI : Evidence from Italian Associations Worldwide
MARINA MURAT;BARBARA PISTORESI;ALBERTO RINALDI 경제연구소 2011 Journal of Economic Development Vol.36 No.4
This paper studies the influence of a country’s transnational social capital - defined as the shared customary values and beliefs of emigrant communities - on its external transactions. It uses Italy’s emigrant associations abroad as a proxy of transnational social capital and measures its effects on Italy’s bilateral FDI. Our results are that the associative activity of emigrants, which partly dates far back into the past, positively and strongly affects the Italian bilateral FDI, especially concerning the countries hosting the older associations and the FDI into Italy.
Improving spaCy dependency annotation and PoS tagging web service using independent NER services
Colic, Nico,Rinaldi, Fabio Korea Genome Organization 2019 Genomics & informatics Vol.17 No.2
Dependency parsing is often used as a component in many text analysis pipelines. However, performance, especially in specialized domains, suffers from the presence of complex terminology. Our hypothesis is that including named entity annotations can improve the speed and quality of dependency parses. As part of BLAH5, we built a web service delivering improved dependency parses by taking into account named entity annotations obtained by third party services. Our evaluation shows improved results and better speed.

The present study is devoted to the influence of a superposed radial inflow in a rotor-stator cavity with a peripheral opening. The flow regime is turbulent, the two boundary layers being separated by a core region. An original theoretical solution is obtained for the core region, explaining the reason why a weak radial inflow has no major influence near the periphery of the cavity but strongly affects the flow behavior near the axis. The validity of the theory is tested with the help of a new set of experimental data including the radial and tangential mean velocity components, as well as three components of the Reynolds stress tensor measured by hot-wire anemometry. The theoretical results are also in good agreement with numerical results obtained with the Fluent code and experimental data from the literature.
