Implementazione di metodi per la misura della qualità dell’energia: attività sperimentale (2004)

Il problema di individuare le responsabilità del deterioramento della qualità dell’energia ha sempre suscitato grande interesse e in letteratura sono numerose le proposte di metodi di misura orientate alla soluzione di tale problema. E’ ormai opinione ampiamente condivisa che metodi basati su misure contemporanee in tutti i nodi della rete elettrica considerata siano in grado di fornire risultati più attendibili di quelli ottenuti da modelli basati su misure acquisite in un solo punto della rete. La loro realizzazione, tuttavia, richiede in generale sistemi complessi e costosi. Gli autori hanno applicato tali tecniche sia a reti di prova IEEE simulate sia a una rete elettrica appositamente realizzata in laboratorio. In questo articolo vengono riassunti i principali risultati dell’attività sperimentale.

High temperature–high pressure thermal conductivities of ethylene and propane (1979)

Thermal conductivities λ of ethylene and propane were measured in the temperature and pressure ranges 400–750 K and 0.1–2.65 MPa (ethylene) and 400–725 K and 0.1 to 0.6 MPa (propane). The data were correlated by expressions of the form λ=λ0(T) ×λp(P), with λ0 being a second order polynomial in temperature and λp a third (ethylene) or a fourth (propane) order polynomial in pressure. The results obtained were compared with previous thermal conductivity measurements.
Selection of energy optimized pump concepts for multi core and multi mode erbium doped fiber amplifiers (2014)

The selection of an appropriate pump concept has a major impact on amplifier cost and power consumption. The energy efficiency of different pump concepts is compared for multi core and multi mode active fibers. In preamplifier stages, pump power density requirements derived from full C-band low noise WDM operation result in superior energy efficiency of direct pumping of individual cores in a multi core fiber with single mode pump lasers compared to cladding pumping with uncooled multi mode lasers. Even better energy efficiency is achieved by direct pumping of the core in multi mode active fibers. Complexity of pump signal combiners for direct pumping of multi core fibers can be reduced by deploying integrated components.
PHOTOLUMINESCENCE AND TEMPERATURE-DEPENDENT EMISSION STUDIES OF Au25 CLUSTERS IN THE SOLID STATE (2009)

Effect of ligand exchange on the optical and photoluminescence properties of Au 25 SG 18 ( SG -glutathione thiolate) clusters was investigated. A fluorescein-based dye, 5-((2-(and-3)-S-(acetylmercapto)succinoyl)amino)-fluorescein (SAMSA) was anchored on water soluble Au 25 SG 18 clusters by the place exchange reaction and the solid-state emission of the exchange product was studied. Inherent fluorescence image of these clusters was mapped. Organic soluble Au 25 ( SC 2 H 4 Ph 18 clusters were synthesized as a model system which also showed temperature-dependent solid-state emission, in good agreement with the results from water soluble Au 25 clusters.
Formation of Palladium Nanostructures in a Seed-Mediated Synthesis through an Oriented-Attachment-Directed Aggregation (2009)

In the present article, we studied the structuration mechanism of palladium nanocrystals (NCs) of different shapes (cubes, pentatwinned nanorods, pyramids, and pentatwinned decahedra) prepared via the seed-mediated reduction of a palladium salt in aqueous medium, in the presence of CTAB surfactant. A detailed time-resolved TEM kinetic study of the formation of the NCs and the investigation of the influence of seeds size the characteristics of the final particles were performed. At the opposite of the gold reference synthesis reported in literature, the systematic presence of numerous very small palladium spherical nuclei generated by homogeneous nucleation was observed. A formation mechanism was proposed, taking into account an early aggregation step of the preformed seeds with some nuclei; this led to the formation of secondary objects with nonrandom shapes, the growth of which led eventually to the final well-faceted palladium NCs. An oriented attachment of seeds and nuclei, triggered by the energetically most favorable packing of spheres, was found to be responsible for the early differentiation of NCs shapes. The original formation mechanism presented here shed a new light on the seed-mediated synthesis of palladium NCs by (i) explaining shape differentiations via an oriented attachment process and (ii) explaining in detail the influence of the CTAB surfactant, the seed size on nuclei size ratio, the solvent, and the temperature onto final NCs shapes.

Platooning Safety and Capacity in Automated Electric Transportation (2021)

Automated Electric Transportation (AET) proposes a system of automated platooning vehicles electrically powered by the roadway via wireless inductive power transfer. This has the potential to provide roadway transportation that is less congested, more flexible, cleaner, safer, and faster than the current system. The focus of this research is to show how platooning can be accomplished in a safe manner and what capacities such an automated platooning system can achieve. To accomplish this, first two collision models are developed to show the performance of automated platoons during an emergency braking scenario: a stochastic model coded in Matlab/Simulink and a deterministic model with closed-form solutions. The necessary parameters for safe platooning are then defined: brake variances, communication delays, and maximum acceptable collision speeds. The two collision models are compared using the Student's t-test to show their equivalence. It is shown that while the two do not yield identical results, in most cases the results of the deterministic model are more conservative than and reasonably close to the results of the deterministic model. The deterministic model is then used to develop a capacity model describing automated platooning flow as a function of speed and platoon size. For conditions where platooning is initially unsafe, three amelioration protocols are evaluated: brake derating, collaborative braking, and increasing the maximum acceptable collision speed. Automated platooning flow is evaluated for all of these scenarios, compared both with each other and with traditional roadway flow patterns. The results of these models show that when platooning is initially safe, very high vehicle flows are possible: for example, over 12,000 veh/hr for initial speeds of 30 m/s and 10 vehicle platoons. Varying system paramaters can have large ramifications for overall capacity. For example, autonomous (non-platooning) vehicles do not promise anywhere near this level, and in many cases struggle to approach the capacity of traditional roadways. Additionally, ensuring safety under an emergency braking standard requires very small communication delays and, most importantly, tight braking variances between the vehicles within a platoon. As proposed by AET, a single type of electric vehicle, combined with modern wireless communications, can make platooning safer than was previously possible without requiring amelioration. Both brake derating and collaborative braking can make platooning safer, but they reduce capacity and may not be practical for real-world implementation. Stricter versions of these, cumulative brake derating and exponential collaborative braking, are also evaluated. Both can degrade capacity to near current roadway levels, especially if a large degree of amelioration is required. Increasing maximum acceptable collision speed, such as through designing vehicles to better withstand rear-end collisions, shows more promise in enabling safe intraplatoon interactions, especially for scenarios with small communication delays (i.e. under 50 ms).
Multiplexed imaging of human tuberculosis granulomas uncovers immunoregulatory features conserved across tissue and blood (2020)

Abstract Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis that is distinctly characterized by granuloma formation within infected tissues. Granulomas are dynamic and organized immune cell aggregates that limit dissemination, but can also hinder bacterial clearance. Consequently, outcome in TB is influenced by how granuloma structure and composition shift the balance between these two functions. To date, our understanding of what factors drive granuloma function in humans is limited. With this in mind, we used Multiplexed Ion Beam Imaging by Time-of-Flight (MIBI-TOF) to profile 37 proteins in tissues from thirteen patients with active TB disease from the U.S. and South Africa. With this dataset, we constructed a comprehensive tissue atlas where the lineage, functional state, and spatial distribution of 19 unique cell subsets were mapped onto eight phenotypically-distinct granuloma microenvironments. This work revealed an immunosuppressed microenvironment specific to TB granulomas with spatially coordinated co-expression of IDO1 and PD-L1 by myeloid cells and proliferating regulatory T cells. Interestingly, this microenvironment lacked markers consistent with T-cell activation, supporting a myeloid-mediated mechanism of immune suppression. We observed similar trends in gene expression of immunoregulatory proteins in a confirmatory transcriptomic analysis of peripheral blood collected from over 1500 individuals with latent or active TB infection and healthy controls across 29 cohorts spanning 14 countries. Notably, PD-L1 gene expression was found to correlate with TB progression and treatment response, supporting its potential use as a blood-based biomarker. Taken together, this study serves as a framework for leveraging independent cohorts and complementary methodologies to understand how local and systemic immune responses are linked in human health and disease.

Solution-Processed Organic Field-Effect Transistors and Unipolar Inverters Using Self-Assembled Interface Dipoles on Gate Dielectrics (2007)

Self-assembled monolayers (SAMs) of polarized and nonpolarized organosilane molecules on gate insulators induced tunable threshold voltage shifting and current modulation in organic field-effect transistors (OFETs) made from solution-deposited 5,5'-bis(4-hexylphenyl)-2,2'-bithiophene (6PTTP6), defining depletion-mode and enhancement-mode operation. p-Channel inverters were made from pairs of OFETs with an enhancement-mode driver and a depletion-mode load to implement full-swing and high-gain organic logic circuits. The experimental results indicate that the shift of the transfer characteristics is governed by the built-in electric field of the SAM. The effect of surface functional groups affixed to the dielectric substrate on the grain appearance and film mobility is also determined.
Multiphysics simulations (2013)

We consider multiphysics applications from algorithmic and architectural perspectives, where “algorithmic” includes both mathematical analysis and computational complexity, and “architectural” includes both software and hardware environments. Many diverse multiphysics applications can be reduced, en route to their computational simulation, to a common algebraic coupling paradigm. Mathematical analysis of multiphysics coupling in this form is not always practical for realistic applications, but model problems representative of applications discussed herein can provide insight. A variety of software frameworks for multiphysics applications have been constructed and refined within disciplinary communities and executed on leading-edge computer systems. We examine several of these, expose some commonalities among them, and attempt to extrapolate best practices to future systems. From our study, we summarize challenges and forecast opportunities.

The synthesis and processing of a nuclear RNA precursor to rat pregrowth hormone messenger RNA (1979)

A recombinant DNA plasmid, pBR322-GH1, which contains about 80% of the sequences of rat pregrowth hormone (pGH) mRNA, allowed an analysis of nuclear RNA from GH3 cells for possible precursors of cytoplasmic pGH mRNA. A single 20-22S RNA SPECIES ABOUT 2-3 TIMes larger than pGH mRNA was detected in nuclear RNA from GH3 cells labeled for 5 min. with 3H-uridine. After longer label times a 12S RNA indistinguishable in size from cytoplasmic 12S pGH mRNA became the predominant labeled RNA complementary to the plasmid pBR322-GH1. Both of these nuclear RNA species contained poly (A). Kinetic analysis of the labeling of nuclear and cytoplasmic pGH mRNA sequences showed that the 20S and 12S nuclear RNA molecules were labeled before significant labeling of cytoplasmic pGH mRNA was detected, and also indicated that there is complete conservation of nuclear pGH mRNA sequences in the production of cytoplasmic pGH mRNA. These results indicate that cytoplasmic pGH mRNA is generated by nuclear processing of a larger nuclear RNA molecule.
Investigation of SrSiO 3 :Ce crystals for scintillator application (2021)

Abstract We developed SrSiO 3 :Ce crystals with different dopant concentrations of 0.5%, 1.0% and 2.0% using the floating zone method and investigated the scintillation and storage luminescence properties. Under X-ray irradiation, a broad emission band peaking at around 360 nm was observed in all the samples. The decay time constants were in the range of 33–34 ns, which were typical values for the 5d–4f transitions of Ce 3+ . The 1.0% and 2.0% Ce-doped samples showed a photoabsorption peak under 241 Am 59.5 keV γ -rays and the light yield was 1200 and 1400 ph MeV −1 , respectively. The results of pulse-height spectra and thermally-stimulated luminescence showed a complementary relationship between scintillation and ionizing-radiation-induced storage luminescence properties in Ce-doped SrSiO 3 .
