Modellazione Analitica e FEM del Meccanismo di trasferimento degli sforzi tra Fondello in Acciaio e Calcestruzzo nelle Travi PREM
No full textLe travi Prefabbricate Reticolari Miste rappresentano una soluzione strutturale ormai in uso da molti anni in grado di coniugare da un lato i vantaggi tipici della prefabbricazione in termini di rapidità costruttiva e risparmio di casseformi dall’altro la monoliticità tipica delle strutture gettate in opera quando adeguatamente curate nelle riprese di getto. Sebbene ormai consolidate nell’uso e nei dettagli costruttivi, le travi reticolari miste sono oggetto di intenso dibattito in quanto alcuni aspetti relativi al loro comportamento sono specifici di tale soluzione strutturale alla quale non sono immediatamente estendibile le conoscenze acquisite per le usuali strutture in cemento armato o composte acciaio calcestruzzo. Tra queste, di interesse appare lo studio del meccanismo di trasferimento degli sforzi tra fondello e calcestruzzo in quanto gli elementi che realizzazione tale trasmissione nel caso delle travi reticolari miste si configurano in modo diverso dalla classica connessione a taglio delle travi in c.a. o miste acciaio-calcestruzzo. In tale contesto si inserisce il presente lavoro, nel quale, partendo dalla calibrazione di un modello agli Elementi Finiti con i risultati di prove sperimentali push-out, viene proposto un modello analitico per la previsione della resistenza allo scorrimento tra fondello in acciaio e anima in calcestruzzo
Partial Laryngeal Surgery in 2023
No full textOpen partial horizontal laryngectomies (OPHLs) have emerged as a pivotal strategy in the conservative treatment of intermediate to advanced stages of laryngeal cancer (LC). This review evaluates the evolution of surgical approaches, focusing on maintaining laryngeal function while ensuring oncological safety. Initially, total laryngectomy dominated the therapeutic landscape, prioritizing tumor control over organ preservation. However, with advancements in understanding LC’s natural history, patient selection and surgical techniques, there has been a paradigm shift towards organ-preserving surgical options like OPHLs. Modern OPHL techniques, backed by enhanced endoscopic and radiological assessments, allow for precise tumor assessment and surgical planning, increasing the likelihood of preserving crucial laryngeal functions such as speech and swallowing. High-definition videolaryngoscopy and magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) have improved the accuracy of pre-operative work-up, thereby refining patient eligibility for partial laryngectomy. The integration of modular surgical approaches and the adoption of new classification by the European Laryngological Society (ELS) further support the versatility of OPHLs in addressing diverse tumor localizations and extents. The review underscores the competitive oncological outcomes of OPHLs compared to non-surgical organ-preservation protocols, highlighting the significant rates of laryngectomy-free survival and the maintenance of laryngeal function. Despite these advances, the treatment of advanced LC remains challenging due to the complex nature of tumor biology and the critical need for precise clinical and pathological assessments. The necessity for a multidisciplinary approach in treatment planning is emphasized to balance oncological control with functional preservation effectively. In conclusion, OPHLs represent a robust option in the current armamentarium for treatment of LC, providing a substantial foundation for enhancing both patient survival and quality of life. The strategic integration of surgical innovations and comprehensive pre-operative assessments is crucial in optimizing treatment outcomes and advancing the field of laryngeal preservation

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
G-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
No full textRanking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc
