Aeroacoustic methods for low-noise technologies design
Creators: name: Barbarino, Mattia
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: As environmental concerns are gaining increased public attention and with the rapid growth of air traffic foreseen in the forthcoming years, the scientific community and aircraft manufacturers are devoting significant resources in developing fast and reliable methods to deliver low noise design solutions.
Since fully-resolved Navier–Stokes equations (DNS), and even filtered Navier-Stokes equations such as LES and DES methods, are still too computationally demanding for real applications, the present dissertation is focused on the theoretical and numerical formulation of different alternative computational aeroacoustic methods and their application to typical aeronautics low noise design problems.
Following an introduction about the theoretical formulation of the Acoustic Analogy approach based on the Lighthill’s equation, the thesis is focused on the development of a Boundary Element Method (BEM) based on the convective wave equation for uniform mean flow.
The BEM code kernel, developed for managing hybrid unstructured grids, builds up the global system matrix by assembling different matrix blocks for the governing equations and the boundary conditions. This strategy allows a more general and efficient implementation of the boundary conditions.
The BEM code is also validated against classical analytical test cases for both internal and external problems.
Moreover, the broadband noise generated by aircraft surfaces (Airframe noise) is presented with particular attention devoted to the development of RANS-based models for source field characterization.
Finally the application of the developed methods to the analysis of the Landing Gear low-noise design problem is presented.

description: Il presente lavoro ha per oggetto il rapporto tra la Gran Bretagna e la Comunità Europea e il modo attraverso il quale esso si è articolato nel corso degli anni. Particolare attenzione è rivolta al periodo storico dominato dalla figura di Margaret Thatcher. Si analizza la posizione critica della Thatcher nei confronti dell'Europa rinvenendone matrici storiche e concettuali. Si osserva in che misura l’azione politica di Margaret Thatcher abbia inciso sulle scelte comunitarie. Si accenna alle questioni ancora aperte tra la Gran Bretagna e l'Unione Europea e alle politiche europee portate avanti dopo la fine del Governo Thatcher.
Coupon Bonds and Liquidation Triggers: A Real Option Approach.
Creators: name: Piccolo, Giovanni
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2013

description: The time between the financial distress and the liquidation is referenced in prior work, but many structural models do not consider this gap. In this document, I implement a real option model in which liquidation starts only if a time variable exceed a pre-defined grace period. Simultaneously, I introduce coupon bonds and liquidation cost in order to have a more realistic model and I use parameters’ value equal to those found in literature (no calibration). Then, I compare cumulative default probabilities, recovery rate and yield spread computed through my approach with those empirically found, in order to understand the reliability of the model.

description: Gravitational particle production in time variable metric of an expanding universe is efficient only when the Hubble parameter $H$ is not too small in comparison with the particle mass. In standard cosmology, the huge value of the Planck mass $M_{Pl}$ makes the mechanism phenomenologically irrelevant. On the other hand, in braneworld cosmology the expansion rate of the early universe can be much faster and many weakly interacting particles can be abundantly created. Cosmological implications are discussed.

description: We propose a new texture for the light neutrino mass matrix. The proposal is based upon imposing zero-trace condition on the two by two sub-matrices of the complex symmetric Majorana mass matrix in the flavor basis where the charged lepton mass matrix is diagonal. Restricting the mass matrix to have two traceless sub-matrices may be found sufficient to describe the current data. Eight out of fifteen independent possible cases are found to be compatible with current data. Numerical and some approximate analytical results are presented.

description: The spectrum of the gravitational wave background originating from quantum fluctuations during inflation is calculated numerically for various inflation models over a wide range of frequencies. We take into account four ingredients : the scalar field dynamics during inflation making no use of the slow-roll approximation, the fermionic decay of the scalar field with a small coupling constant during the reheating process, the change of the effective number of degrees of freedom g_* in the radiation-dominated era, and the anisotropic stress of free-streaming neutrinos. By numerically solving the evolution of gravitational waves during and after inflation up to the present, all of these effects can be examined comprehensively and accurately over a broad spectrum, even at very high frequencies. We find that the spectrum shows (i) a large deviation from the spectrum less accurate obtained by Taylor expanding around the CMB scale using the slow-roll approximation (ii) a characteristic frequency dependence due to the reheating effect, and (iii) damping due to the g_* changes and the neutrino anisotropic stress. We suggest that future analysis of the gravitational wave background should take into consideration the fact that analytical estimates using the Taylor expansion overestimate the amplitude of the spectrum.

Long Range Tensor Correlations in Charge and Parity Projected Fermionic Molecular Dynamics

Publisher: name: arXiv
Year: 2008
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Within the framework of Fermionic Molecular Dynamics a method is developed to better account for long range tensor correlations in nuclei when working with a single Slater determinant. Single-particle states with mixed isospin and broken parity build up an intrinsic Slater determinant which is then charge and parity projected. By minimizing the energy of this many-body state with respect to the parameters of the single-particle states and projecting afterwards on angular momentum ground state energies are obtained that are systematically lower than corresponding Hartree-Fock results. The realistic Argonne V18 potential is used and short range correlations are treated with the Unitary Correlation Operator Method. Comparison with exact few-body calculations shows that in $^4$He about one fifth of the correlation energy due to long-range correlations are accounted for. These correlations which extend over the whole nucleus are visualized with the isospin and spin-isospin density of the intrinsic state. The divergence of the spin-isospin density, the source for pion fields, turns out to be of dipole nature.

More Generalizable Models For Sepsis Detection Under Covariate Shift

description: Sepsis is a major cause of mortality in the intensive care units (ICUs). Early intervention of sepsis can improve clinical outcomes for sepsis patients. Machine learning models have been developed for clinical recognition of sepsis. A common assumption of supervised machine learning models is that the covariates in the testing data follow the same distributions as those in the training data. When this assumption is violated (e.g., there is covariate shift), models that performed well for training data could perform badly for testing data. Covariate shift happens when the relationships between covariates and the outcome stay the same, but the marginal distributions of the covariates differ among training and testing data. Covariate shift could make clinical risk prediction model nongeneralizable. In this study, we applied covariate shift corrections onto common machine learning models and have observed that these corrections can help the models be more generalizable under the occurrence of covariate shift when detecting the onset of sepsis.

Un épisode de la redécouverte de la musique du temps de Dante au XVIe siècle : le Recueil de l’origine de la langue et poesie française, ryme et romans de Claude Fauchet

Publisher: name: Pavia University Press - Edizioni dell'Università degli Studi di Pavia
Year: 2023

description: Tra le fonti liriche in lingua d’oïl cui Dante si è ispirato per le Rime e la Vita Nuova, un’importanza particolare sembra avere Adam de la Halle. Tra i numerosi manoscritti della produzione di quest’ultimo giunti fino a noi, alcuni furono posseduti dal magistrato bibliofilo e erudito Claude Fauchet (1530-1602), autore di una delle prime storie della letteratura francese medievale nella seconda metà del Cinquecento. L’analisi delle fonti che ebbe a disposizione per la redazione della sua breve presentazione di Adam de la Halle nel Recueil de l’origine de la langue et poesie française, ryme et romans (1581) permetterà di spiegare perché questo giurista-scrittore, generalmente molto ben documentato e in grado di fornire un quadro abbastanza preciso della letteratura medievale in lingua d’oïl, abbia gettato uno sguardo frettoloso su un poeta e compositore considerato tra i più rappresentativi del secolo XIII.

X-ray binary accretion states in Active Galactic Nuclei? Sensing the accretion disc of supermassive black holes with mid-infrared nebular lines

description: Accretion states, which are universally observed in stellar-mass black holes in X-ray binaries, are also anticipated in active galactic nuclei (AGN). This is the case at low luminosities, when the jet-corona coupling dominates the energy output in both populations. Previous attempts to extend this framework to a wider AGN population have been extremely challenging due to heavy hydrogen absorption of the accretion disc continuum and starlight contamination from the host galaxies. We present the luminosity-excitation diagram (LED), based on the [OIV]$_{25.9μm}$ and [NeII]$_{12.8μm}$ mid-infrared nebular line fluxes. This tool enables to probe the accretion disc contribution to the ionising continuum. When applied to a sample of 167 nearby AGN, the LED recovers the characteristic q-shaped morphology outlined by individual X-ray binaries during a typical accretion episode, allowing us to tentatively identify the main accretion states. The soft state would include broad-line Seyferts and about half of the Seyfert 2 population, showing highly excited gas and radio-quiet cores consistent with disc-dominated nuclei. The hard state mostly includes low-luminosity AGN ($\leq 10^{-3}\, \rm{L_{Edd}}$) characterised by low-excitation radio-loud nuclei and a negligible disc contribution. The remaining half of Seyfert 2 nuclei and the bright LINERs show low excitation at high accretion luminosities, and could be identified with the bright-hard and intermediate states. Their hosts show ongoing star formation in the central kiloparsecs. We discuss the above scenario, its potential links with the galaxy evolution picture and the possible presence of accretion state transitions in AGN, as suggested by the growing population of changing-look quasars.

description: Building on the literature on the influence of geopolitical relations upon international commercial interactions and the growing discussion on the political implication of Chinese OFDI, I investigated the relationship between countries’ political alignment with China and the US and the Chinese government’s evaluation of the FDI climate in these countries. Using dictionary-based text analysis, I extracted the sentiments in the country-based FDI climate evaluation reports to measure the Chinese government’s preference on overseas FDI climate. By combining the sentiment scores with the UNGA voting data in a pooled OLS regression, I further explored the influence of geopolitical pressure on how the Chinese government encouraged domestic firms to invest abroad. I found significant evidence that the Chinese government tend to put extra favor on the countries that are politically aligned with China and countries that are politically deviated from the US, which supports the argument that Chinese government is guiding domestic firms to invest based on political interests.

description: The ground state properties of CeFePO, a homologue of the new high temperature superconductors RFePnO(1-x)Fx, were studied by means of susceptibility, specific heat, resistivity, and NMR measurements on polycrystals. All the results demonstrate that this compound is a magnetically non-ordered heavy Fermion metal with a Kondo temperature TK~10K, a Sommerfeld coefficient gamma=700mJ/molK2 and a mass enhancement factor of the order of 200. The absence of a Fe-contribution to the effective moment at high temperatures indicates that the magnetism in CeFePO is completely dominated by the effect of Ce. Thus the strong electronic correlation effects originate from the Ce-4f electrons rather than from the Fe-3d electrons. An enhanced Sommerfeld-Wilson ratio R=5.5 as well as a Korringa product S0/T1TK2~0.065 well below 1 indicate the presence of ferromagnetic correlations. Therefore, CeFePO appears to be on the non-magnetic side of a ferromagnetic instability.

Subjects: Autobiography; language and identity; Jorge Semprún; phraseology; twentieth-century Spanish novel

description: Jorge Semprún (Madrid, 1923 - Paris, 2011) wrote novels in two languages, French and Spanish. His schizophrenic bilingualism led him to say that his homeland was language in general, not a language (his particular phraseology may be interpreted as a symptom of his illness). In both French and Spanish his fiction is deeply autobiographical. Indeed, literature seems to have been the writer’s lifesaver, the context in which he affirmed his at least double identity (without forgetting, however, the importance of German). This double identity he proudly affirmed both in politics and writing, which alternate and nurture each other throughout his life and by means of which he struggled to change the world, passionately committing himself to the making of Europe.

description: Background— Limited data exists regarding occurrence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) reinfection among healthcare workers (HCWs). We report upon five SARS-CoV-2 reinfections seen among HCWs with associated risk factors and disease characteristics.Methods— We identified five HCWs with a history of SARS-CoV-2 infection from one tertiary care hospital in Peshawar, Pakistan, who reported recurrent symptoms of SARS-CoV-2 using HCW self-reporting, who were subsequently diagnosed with reinfection of SARS-CoV-2 by nasopharyngeal Polymerase chain reaction (PCR). We studied disease characteristics, duration between the primary and reinfection, vaccination status, and outcomes using a standardized questionnaire.Results— The mean duration between primary and reinfection was 174.4 days ± standard deviation (SD) 26.8 days. The mean age of the HCWs was 28.6 years ± SD 2.9 years; three of five HCWs were men. All five unvaccinated HCWs reported fever, body aches, cough, loss of taste and smell were more severe with reinfection compared to primary infection. One male HCW reported symptoms of mild depression with primary SARS-CoV-2 infection and subsequently reported symptoms of moderate depression and diarrhea with reinfection. No HCWs had hypoxia or required hospitalization with either primary or reinfection.Conclusions— Our study emphasized the risk of SARS-CoV-2 reinfection among HCWs. Reinfection may be associated with more severe symptoms compared with primary infection. Larger studies involving HCWs and general population studies are needed to further identify the risks, prevention, duration of natural immunity, and beneficial role of immunization and booster immunization.

description: A geometric approach to time-dependent optimal control problems is proposed. This formulation is based on the Skinner and Rusk formalism for Lagrangian and Hamiltonian systems. The corresponding unified formalism developed for optimal control systems allows us to formulate geometrically the necessary conditions given by Pontryagin's Maximum Principle, provided that the differentiability with respect to controls is assumed and the space of controls is open. Furthermore, our method is also valid for implicit optimal control systems and, in particular, for the so-called descriptor systems (optimal control problems including both differential and algebraic equations).

Interpolating 't Hooft model between instant and front forms

description: The 't Hooft model, i.e. the two-dimensional quantum chromodynamics in the limit of infinite number of colors, is interpolated by an angle parameter $δ$ between $δ=0$ for the instant form dynamics (IFD) and $δ=π/4$ for the light-front dynamics (LFD). With this parameter $δ$, we formulate the interpolating mass gap equation which takes into account the non-trivial vacuum effect on the bare fermion mass to find the dressed fermion mass. Our interpolating mass gap solutions link the IFD and LFD results with the $δ$ parameter. We find the interpolation angle independent characteristic energy function which satisfies the energy-momentum dispersion relation of the dressed fermion, identifying the renormalized fermion mass function and the wave function renormalization factor. Using the dressed fermion propagator interpolating between IFD and LFD, we derive the corresponding quark-antiquark bound-state equation in the interpolating formulation. The mass spectra of mesons bearing the feature of the Regge trajectories are found independent of the $δ$-parameter for the equal mass quark and antiquark bound-states. The Gell-Mann - Oakes - Renner relation for the pionic ground-state in the zero fermion mass limit is confirmed indicating that the spontaneous breaking of the chiral symmetry occurs regardless of the quantization for $0 \le δ\le π/4$. We obtain the corresponding bound-state wave functions and discuss their reference frame dependence. Applying them for the computation of the so-called quasi parton distribution functions, we note a possibility of utilizing not only the reference frame dependence but also the interpolation angle dependence to get an alternative effective approach to the LFD-like results.

An anomaly-free symmetry demands nontrivial conditions on the charges of the unavoidable new states. An intensive scan was performed, looking for solutions generating neutrino masses by the type-I and type-II tree-level Dirac seesaw mechanism, via operators with dimension 5 and 6, that correspond to active or dark symmetries. Special attention was paid to the cases featuring no extra massless chiral fermions or multicomponent dark matter with unconditional stability.

description: An experiment is proposed, on the coherent quantum dynamics of a semiconductor microcavity containing quantum dots. Modeling the experiment using a generalized Dicke model, we show that a tailored excitation pulse can create an energy-dependent population of excitons, which subsequently evolves to a quantum condensate of excitons and photons. The population is created by a generalization of adiabatic rapid passage, and then condenses due to a dynamical analog of the BCS instability.

description: Magnetic ordering phenomena in CexPr1-xB6 solid solutions have been studied using both powder and single-crystal neutron diffraction. A variety of magnetic structures are observed depending on temperature and Ce concentration. Over a broad composition range (x $\le$ 0.7), Pr-Pr interactions play a dominant role, giving rise to incommensurate structures with wave vectors of the form k{IC1}=(1/4-delta, 1/4, 1/2) or k{IC2}=(1/4-delta, 1/4-delta, 1/2). The crossover to a CeB6-like regime takes place near x = 0.7-0.8. For the latter composition, the antiferroquadrupolar phase transition observed in transport measurements precedes the onset, at lower temperature, of a commensurate magnetic order similar to that existing in CeB6. However, unlike in the pure compound, an incommensurate magnetic order is formed at even higher temperature and persists in the antiferroquadrupolar phase down to the lock-in transition. These results are shown to reflect the interplay between various type of dipole exchange and higher multipole interactions in this series of compounds.

description: Objective：The moral and ethical issue is a great challenge to the development of autonomous vehicles. There may be distinctions between the choices made by an observer and a participant. The paper is designed to investigate whether drivers will sacrifice the fewest people to save more people in social dilemma, and whether human drivers would give priority to protecting pedestrians or self-protection in an emergency. Methodology: The experiment was conducted with a total of 50 participants assigned to three groups. Three experimental scenarios were designed and each of them contained a social dilemma. A driving simulator was used in this study to explore the choices of human drivers in social dilemma. In addition, the simulator results were compared with those of questionnaire survey. Result: In study 1, 73% of 22 participants swerved into the right lane to hit only one pedestrian for the safety of other five. In study 2 and 3, more participants chose to hit the barrier to protect the pedestrian. Conclusion: A conclusion can be drawn from the second and third group of experiments that most drivers consider not only their own safety, but the safety of pedestrians. Most of the participants intended to minimize the total amount of harm in social dilemma. The choice of crashing into barriers to protect a pedestrian can also be seen as a way to minimize the total amount of harm.

description: To expand the range in the colour-magnitude diagram where asteroseismology can be applied, we organized a photometry campaign to find evidence for solar-like oscillations in giant stars in the globular cluster M4. The aim was to detect the comb-like p-mode structure characteristic for solar-like oscillations in the amplitude spectra. The two dozen main target stars are in the region of the bump stars and have luminosities in the range 50-140 Lsun. We collected 6160 CCD frames and light curves for about 14000 stars were extracted. We obtain high quality light curves for the K giants, but no clear oscillation signal is detected. High precision differential photometry is possible even in very crowded regions like the core of M4. Solar-like oscillations are probably present in K giants, but the amplitudes are lower than classical scaling laws predict.

description: Using a Glauber model with our relativistic fully microscopic structure model input, we give a full description of the halo nature of 31Ne that includes a self-consistent use of pairing and continuum contributions that makes predictions consistent with reaction cross section measurements. Our predictions of total reaction and one-neutron removal cross sections of 31Ne on a Carbon target were significantly enhanced compared with those of neighboring Neon isotopes, agreeing well with measurements at 240 MeV/nucleon and consistent with a single neutron halo. Furthermore, our calculations of the inclusive longitudinal momentum distribution of the 30Ne and valence neutron residues from the 31Ne breakup reaction indicate a dilute density distribution in coordinate space, another halo signature.

description: The electronic density of states of graphene is equivalent to that of relativistic electrons. In the absence of disorder or external doping the Fermi energy lies at the Dirac point where the density of states vanishes. Although transport measurements at high carrier densities indicate rather high mobilities, many questions pertaining to disorder remain unanswered. In particular, it has been argued theoretically, that when the average carrier density is zero, the inescapable presence of disorder will lead to electron and hole puddles with equal probability. In this work, we use a scanning single electron transistor to image the carrier density landscape of graphene in the vicinity of the neutrality point. Our results clearly show the electron-hole puddles expected theoretically. In addition, our measurement technique enables to determine locally the density of states in graphene. In contrast to previously studied massive two dimensional electron systems, the kinetic contribution to the density of states accounts quantitatively for the measured signal. Our results suggests that exchange and correlation effects are either weak or have canceling contributions.

Interplay between Ticagrelor, Adenosine and Caffeine: Effect on Ticagrelor Tolerability and Efficacy
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background— Ticagrelor, a P2Y12 adenosine diphosphate receptor inhibitor, can be associated with dyspnea which may necessitate its discontinuation. Caffeine has been proposed to reduce occurrence of dyspnea in patients on ticagrelor.Case Description— A 61-year-old woman presented with dysarthria, dizziness, gait imbalance, and episodes of falls associated with diffuse and severe vertebrobasilar intracranial atherosclerosis. Aspirin and clopidogrel were initiated but clopidogrel was substituted with ticagrelor due to suboptimal platelet inhibition as measured by thromboelastography-platelet mapping. Patient developed dyspnea within 45 minutes of ticagrelor administration. Oral caffeine in doses of 200mg twice daily was started with improvement in modified Borg dyspnea score from 3 to 0. After caffeine administration, inhibition of adenosine diphosphate-mediated platelet aggregation decreased from 67.8% to 34.6%.Conclusions— Although the dyspnea improved with caffeine pre-medication, the magnitude of platelet inhibition was adversely affected in our patient on ticagrelor.
