Rheological characterization of the paste showed a yield stress of ∼8 Pa and shear thinning behavior (ΔG′/Δσ* = −55). The paste was printed using a 610 μm nozzle; a test print showed shape fidelity using the developed paste. A pressureless …

Effect Of Sc Spatial Distribution On The Electronic And Ferroelectric Properties Of Alscn, Bipin Bhattarai, Xiaoman Zhang, Wangwang Xu, Yijia Gu, W. J. Meng, Andrew C. Meng

Materials Science and Engineering Faculty Research & Creative Works

While aluminum scandium nitride based ferroelectric materials have shown significant promise for non-volatile memory applications, difficulties relating challenges in device performance, such as electrical leakage, to structural characteristics motivate improved understanding of the fundamental structure-property relationship. Spinodal decomposition has been reported in this material system, consistent with our observation of compositional segregation in AlScN films grown by reactive sputter epitaxy. To better understand the effects of spatially non-uniform Sc concentrations, the electronic and ferroelectric (FE) properties of AlScN as a function of Sc distribution are studied using density functional theory (DFT). We explore the impact of Sc-rich atomic planes in …

Endocrown, From Preparation To Bonding: Case Report, Amira Yousfi, Rihab Dakhli, Jilani Saafi, Belhassen Harzallah

International Arab Journal of Dentistry

The restoration of endodontically treated teeth is a real challenge, particularly teeth with extensively damaged coronal tissues. The use of post-retained restorations has been discussed because of the potential tooth weakening due to the additional removal of sound dental structures. In fact, long-term prognosis of a devitalized tooth is closely related to the coronal restoration’s quality and the remaining dental structure. With the development of adhesive dentistry and minimally invasive preparation, new approaches have emerged. Among them, the endocrown which is monolithic ceramic bonded restoration, anchored to the internal portion of pulp chamber and cavity margins that have been used …

Thermodynamic Analysis Of Metal Segregation In Dual Phase High Entropy Ceramics, Steven M. Smith, William G. Fahrenholtz, Gregory E. Hilmas, Stefano Curtarolo

Materials Science and Engineering Faculty Research & Creative Works

Equilibrium Gibbs' free energy calculations were used to determine metal segregation trends between boride and carbide solid solutions containing two metals that are relevant to dual phase high entropy ceramics. The model predicted that Ti had the strongest tendency to segregate to the boride phase followed by Zr, Nb, Mo, V, Hf, and Ta, which matches experimental results of measured compositions. The ratio of a metal in the carbide phase to the content of the same metal in the corresponding metal boride had a linear trend with the change in standard Gibbs' free energy of reaction for a metal carbide …

Conscientious Objection And Abortion: The Italian Pseudo-Exceptionalism, C. Crea

FIU Law Review

Threats to abortion and reproductive rights are well-rooted in global discursive and strategic practices promoted by conservative and ‘pro-life’ movements and narratives. Starting from these premises, this essay will focus on abortion access in Italy and the barrier caused by conscientious objection among medical personnel, which appears indefensible in light of both international human rights regimes and philosophical-theoretical perspectives. The main questions explored here are the following: Is conscientious objection to abortion really based on Catholic moral teaching, which constitutes the conventional religious wisdom of the national societal fabric? How and to what extent are Catholic and conservative moral narratives …

Italian Comparative: A Trait Of The Legal System, Bianca Gardella Tedeschi

FIU Law Review

The cultural environment of Italian academia was open to suggestions that came from other legal systems and shaped an eclectic legal culture. Italy is an hybrid system that took the code from France, the legal science from Germany, and has always been receptive of foreign suggestions. This cultural background may explain why the Italian legal curriculum requires a mandatory course of comparative law and why comparative law has been an important field of Italian legal research. At the same time, comparative law was characterized by an an important mark of antiformalism, necessary to swim through the times of Fascism and …

Urban Commons In Italy, Michele Graziadei

FIU Law Review

The Italian experience with urban commons has been very rich indeed. In the last ten years or so the number of social and legal initiatives relating to urban commons in Italy has exploded. The present Italian situation shows that urban commons are here to stay. By now, they are part of the collective imagination, of political and socio-economic transformative projects, of administrative practices, and of the law. The demand for the commons in the city originates from the social movements that intend to resist the penetration of the market and of private property in every ambit of life but is …

Towards A Concurrency Platform For Scalable Multi-Axial Real-Time Hybrid Simulation, Marion Sudvarg, Oren Bell, Tyler Martin, Benjamin Standaert, Tao Zhang, Sun Beom Kwon, Chris Gill, Arun Prakash

Computer Science Faculty Research & Creative Works

Multi-axial real-time hybrid simulation (maRTHS) uses multiple hydraulic actuators to apply loads and deform experimental substructures, enacting both translational and rotational motion. This allows for an increased level of realism in seismic testing. However, this also demands the implementation of multiple-input, multiple-output control strategies with complex nonlinear behaviors. To realize true real-time hybrid simulation at the necessary sub-millisecond timescales, computational platforms will need to support these complexities at scale, while still providing deadline assurance. This paper presents initial work towards supporting (and is influenced by the need for) envisioned larger-scale future experiments based on the current maRTHS benchmark: it discusses …

Minerrouter : Effective Message Routing Using Contact-Graphs And Location Prediction In Underground Mine, Abhay Goyal, Sanjay Madria, Samuel Frimpong

Computer Science Faculty Research & Creative Works

Location-based distributed communication in underground mines has been a hard problem to solve due to unreliable centralized architecture such as leaky feeder systems, high attenuation, and the unavailability of GPS signals. Delay Tolerant Networks (DTN) enable decentralized message routing using the store-carry-forward method that can help in creating situational awareness needed to handle emergency and disaster scenarios. The ability to predict where the DTN nodes (miner) might have been at/are headed to (with respect to the mine regions and pillars) at different times, combined with contact-based routing and intelligent handling of buffer, can be used for better delivery of messages. …

Five Considerations For Twenty-First Century Climate Policy, Matthew G. Burgess

FIU Law Review

As the twenty-first century advances, society is entering a new phase regarding climate change. Impacts of climate change are becoming more salient in the present, rather than being only far-off in the future. Progress on flattening—and in many affluent countries, reducing—greenhouse gas emissions is also becoming salient, though the progress underperforms international targets. Slowing economic growth and major technological and geopolitical disruptions are creating new challenges and uncertainties. One of these challenges is a political climate of deep divisions and rising distrust in fact-finding institutions—a climate that is ripe for demagoguery. In the United States and some other countries, the …
