description: Patients who are admitted to the hospital after sustaining a large burn injury are at high risk for developing hospital-associated infections. If patients survive the initial 72 hours after a burn injury, infections are the most common cause of death. Ventilator-associated pneumonia is the most important infection in this patient population. The risk of infections caused by multidrug-resistant bacterial pathogens increases with hospital length of stay in burn patients. In the first days of the postburn hospitalization, more susceptible, Gram-positive organisms predominate, whereas later more resistant Gram-negative organisms are found. These findings impact the choice of empiric antibiotics in critically ill burn patients. A proactive infection control approach is essential in burn units. Furthermore, a multidisciplinary approach to burn patients with a team that includes an infectious disease specialist and a pharmacist in addition to the burn surgeon is highly recommended.
FABRICATION and CHARACTERIZATION of BIDIMENSIONAL ELECTRONIC GAS (2DEG) in ZnO BASED HETEROSTRUCTURES
Creators: name: PLAZA, ALEJANDRO ENRIQUE

Year: 2020

description: Spintronics and High Electronic Mobility Transistors (HEMTs) are active frontiers in the development of electronic devices. For their development, Diluted Magnetic Semiconductors (DMS) and heterostructures hosting Two Dimensional Electronic Gas (2DEG) are required. MBE has become into the state of the art technique to prepare ZnO based heterostructures, surpassing PLD limitations. However, the former has a much more complex operation and higher costs. In order to improve the quality of ZnO based heterostructures at bounded costs, a low oxidative MBE process was studied. The aim of the present thesis is double: first, it intends to make a contribution to the knowledge of the non conventional low oxidative MBE production of ZnO heterostructures. In particular we wanted to assess its feasibility and understand the growth mechanism. Second, this thesis intends to make specific contributions to the physics of electric transport in such heterostructures, namely Electric Field modulated Magnetoresistance and 2DEG Magnetic Field Effective Mass Enhancement. For the first objective, 142 MgO/ZnO heterostructures were grown on sapphire on a home-made MBE in low oxidative conditions. An extensive characterization of the sample set by RHEED, AFM, XRD, SEM, EDS and Transport measurement was carried out. The analysis of the data gathered made it possible to identify different growth stages of the ZnO structures. They were mainly discussed in terms of misfit accommodation. The results suggest a complex process with interlinked steps, in which subtle transformations take place. For the second objective, Field Effect devices were produced by depositing Co:ZnO/STO heterostructures by PLD. After XRD, AFM, TEM and magnetic characterization, transport measurements were carried out. The magnetic scattering was studied by appropriate model fitting and discussed in terms of percolation of Bounded Magnetic Polarons (BMP). The results suggest free charge carrier mediated magnetic polarization of Co:ZnO. Next, a 2DEG hosting Mg:ZnO/ZnO heterostructure was deposited by PLD. Transport measurements showed complex quantum oscillations. The simultaneous model fitting for all temperatures showed magnetic field effective mass enhancement. The results suggest band non-parabolicity and electron-electron correlation as possible causes.

description: Statistical measures of chaos have long been used in the study of chaotic dynamics in the framework of the interacting boson model. The use of large number of bosons renders additional studies of chaos possible, that can provide a direct comparison with similar classical studies of chaos. We intend to provide complete quantum chaotic dynamics at zero angular momentum in the vicinity of the arc of regularity and link the results of the study of chaos using statistical measures with those of the study of chaos using classical measures. Statistical measures of chaos are applied on the spectrum and the transition intensities of 0+ states in the framework of the interacting boson model. The energy dependence of chaos is provided for the first time using statistical measures of chaos. The position of the arc of regularity was also found to be stable in the limit of large boson numbers. The results of the study of chaos using statistical measures are consistent with previous studies using classical measures of chaos, as well as with studies using statistical measures of chaos, but for small number of bosons and states with angular momentum greater than 2.

Year: 2017

description: Patient-care items can serve as a source or reservoir for healthcare-associated pathogens in hospitals. We reviewed healthcare-associated outbreaks from medical equipment and provide infection prevention recommendations. Multiple healthcare-associated outbreaks via a contaminated patient-care item were identified, including infections with multidrug-resistant organisms. The type of patient care items implicated as a fomite causing healthcare-associated infections (HAIs) has changed over time. Patient populations at r isk were most commonly cr itically i ll patients in adult and neonatal intensive care units. Most fomite related healthcare-ass ociated outbreaks were due to inappropriate disinfection practices. Repeated healthcare-associated outbreaks via medical equipment highlight the need for infectious disease professionals to understand that fomites/medical devices may be a source of HAIs. The introduction of new and more complex medical devices will likely increase the risk that such devices serve as a source of HAIs. Assuring appropriate cleaning and disinfection or sterilization of medical equipment is necessary to prevent future fomite-associated outbreaks.

description: Improving the understanding of strongly correlated quantum many body systems such as gases of interacting atoms or electrons is one of the most important challenges in modern condensed matter physics, materials research and chemistry. Enormous progress has been made in the past decades in developing both classical and quantum approaches to calculate, simulate and experimentally probe the properties of such systems. In this work we use a combination of classical and quantum methods to experimentally explore the properties of an interacting quantum gas by creating experimental realizations of continuous matrix product states - a class of states which has proven extremely powerful as a variational ansatz for numerical simulations. By systematically preparing and probing these states using a circuit quantum electrodynamics (cQED) system we experimentally determine a good approximation to the ground-state wave function of the Lieb-Liniger Hamiltonian, which describes an interacting Bose gas in one dimension. Since the simulated Hamiltonian is encoded in the measurement observable rather than the controlled quantum system, this approach has the potential to apply to exotic models involving multicomponent interacting fields. Our findings also hint at the possibility of experimentally exploring general properties of matrix product states and entanglement theory. The scheme presented here is applicable to a broad range of systems exploiting strong and tunable light-matter interactions.

AMPLITUDE ANALYSIS AND POLARISATION MEASUREMENT OF THE LAMBDAC BARYON IN PKPI FINAL STATE FOR ELECTROMAGNETIC DIPOLE MOMENT EXPERIMENT
Creators: name: MARANGOTTO, DANIELE
Publisher: name: Universit� degli Studi di Milano
Year: 2020

description: The first part of the thesis presents an experiment proposal for short-lived heavy baryon electromagnetic dipole moments measurement, exploiting spin precession of particles channeled in bent crystals, produced from fixed-target collisions of multi-TeV energy protons extracted from the main beam of the Large Hadron Collider accelerator. The LHCb detector is considered to measure the baryon polarisation from its decay distribution. The same methodology is further extended to the measurement of ? lepton electromagnetic dipole moments, which is complicated by the presence of undetectable neutrinos. The second part of the thesis presents the amplitude analysis of ?c ? pK? decays from ?b ? ?c ? X production recorded by the LHCb experiment, including the extraction of the ?c polarisation vector. This analysis is an essential tool in light of the ?c baryon dipole moments measurement, providing an unprecedented knowledge of the main ?c decay mode and the ?c polarisation. Order one million events are selected from LHCb data with negligible background contributions. The ?c ? pK? decay model for generic polarisation is written in the helicity formalism and fitted to data. An amplitude model describing ?c ? pK? decays has been obtained from two-dimensional Dalitz plot fits, giving valuable information on the main intermediate resonances, including the observation of new ?* resonant contributions. The third part of the thesis deals with the ?c polarisation measurement in proton-neon collisions at 68.6 GeV centre-of-mass energy recorded by LHCb, which provides information on the ?c baryon structure. A significant ?c polarisation is also crucial for the proposed dipole moments experiment. The feasibility of the measurement has been proved achieving two essential results: a few hundreds ?c ? pK? decays are selected from proton-neon LHCb data, separated from background contributions; the ?c polarisation measurement from the selected sample has been proved feasible on simulated pseudo-experiments, showing that the main associated systematic uncertainty is negligible compared to statistical fluctuations.

description: Designing high-finesse resonant cavities for electronic waves faces challenges due to short electron coherence lengths in solids. Previous approaches, e.g. the seminal nanometer-sized quantum corrals, depend on careful positioning of adatoms at clean surfaces. Here we demonstrate an entirely different approach, inspired by the peculiar acoustic phenomena in whispering galleries. Taking advantage of graphene's unique properties, namely gate-tunable light-like carriers, we create Whispering Gallery Mode (WGM) resonators defined by circular pn-junctions, induced by a scanning tunneling probe. We can tune the resonator size and the carrier concentration under the probe in a back-gated graphene device over a wide range, independently and in situ. The confined modes, revealed through characteristic resonances in the tunneling spectrum, originate from Klein scattering at pn junction boundaries. The WGM-type confinement and resonances are a new addition to the quantum electron-optics toolbox, paving the way to real-world electronic lenses and resonators.

description: Statistical arbitrage methods identify mispricings in securities with the goal of building portfolios which are weakly correlated with the market. In pairs trading, an arbitrage opportunity is identified by observing relative price movements between a pair of two securities. By simultaneously observing multiple pairs, one can exploit different arbitrage opportunities and increase the performance of such methods. However, the use of a large number of pairs is difficult due to the increased probability of contradictory trade signals among different pairs. In this paper, we propose a novel portfolio construction method based on preference relation graphs, which can reconcile contradictory pairs trading signals across multiple security pairs. The proposed approach enables joint exploitation of arbitrage opportunities among a large number of securities. Experimental results using three decades of historical returns of roughly 500 stocks from the S\&P 500 index show that the portfolios based on preference relations exhibit robust returns even with high transaction costs, and that their performance improves with the number of securities considered.

description: In multi-parameter models, reference priors typically depend on the parameter or quantity of interest, and it is well known that this is necessary to produce objective posterior distributions with optimal properties. There are, however, many situations where one is simultaneously interested in all the parameters of the model or, more realistically, in functions of them that include aspects such as prediction, and it would then be useful to have a single objective prior that could safely be used to produce reasonable posterior inferences for all the quantities of interest. In this paper, we consider three methods for selecting a single objective prior and study, in a variety of problems including the multinomial problem, whether or not the resulting prior is a reasonable overall prior.

description: The data acquisition system (DAQ) of the future Cherenkov Telescope Array (CTA) must be ef- ficient, modular and robust to be able to cope with the very large data rate of up to 550 Gbps coming from many telescopes with different characteristics. The use of modern middleware, namely ZeroMQ and Protocol Buffers, can help to achieve these goals while keeping the development effort to a reasonable level. Protocol Buffers are used as an on-line data for- mat, while ZeroMQ is employed to communicate between processes. The DAQ will be controlled and monitored by the Alma Common Software (ACS). Protocol Buffers from Google are a way to define high-level data structures through an in- terface description language (IDL) and a meta-compiler. ZeroMQ is a middleware that augments the capabilities of TCP/IP sockets. It does not implement very high-level features like those found in CORBA for example, but makes use of sockets easier, more robust and almost as effective as raw TCP. The use of these two middlewares enabled us to rapidly develop a robust prototype of the DAQ including data persistence to compressed FITS files.

The main feature is that the nonlinearity is localized only in a compact part of the graph. Our main result states that for every integer k, the equation possesses at least k solutions of prescribed mass, provided that the mass is large enough. These solutions arise as constrained critical points of the NLS energy functional. Estimates for the energy of the solutions are also established.

We find the temperature-dependent continuum threshold for each hyperon using the obtained sum rules for their mass and residue. The numerical results demonstrate that the mass and residue of the particles under consideration remain stable up to a certain temperature, after which they decrease by increasing the temperature.

description: As Artificial Intelligence (AI) becomes pervasive in most fields, from healthcare to autonomous driving, it is essential that we find successful ways of building morality into our machines, especially for decision-making. However, the question of what it means to be moral is still debated, particularly in the context of AI. In this paper, we highlight the different aspects that should be considered when building moral agents, including the most relevant moral paradigms and challenges. We also discuss the top-down and bottom-up approaches to design and the role of emotion and sentience in morality. We then propose solutions including a hybrid approach to design and a hierarchical approach to combining moral paradigms. We emphasize how governance and policy are becoming ever more critical in AI Ethics and in ensuring that the tasks we set for moral agents are attainable, that ethical behavior is achieved, and that we obtain good AI.

description: Ultra-precise observations from space missions such as CoRoT, Kepler/K2 or TESS can be contrasted with data from ground-based surveys such as CARMENES or HARPS to validate extra-solar planets detection through spectroscopy or using different photometric bands to discard false positives. Though several thousands of exoplanets have already been confirmed the number of candidates is orders of magnitude higher. Since it is not possible to allocate time from ground-based surveys to perform the follow-up of all the candidates, an automatic validation procedure is required which is robust enough to confirm the detections. I introduce here a new validation method for exoplanet transit candidates based on modeling the data as auto-regressive processes. These can fit either stellar pulsations, stellar activity or any intrinsic variability so they are very suitable to model out of transit light variations. This procedure does not require any a priori from the star or planet such as period, depth, duration or shape of the signal. It neither does require any colors, spectroscopic observations or any informed assumptions, only one light curve with several transits is required. Here I show that transits can be validated with no necessity of follow-up observations in many cases and false positives can be reliably identified with auto-regressive models.

description: The one clean qubit model of quantum computation (DQC1) efficiently implements a computational task that is not known to have a classical alternative. During the computation, there is never more than a small but finite amount of entanglement present, and it is typically vanishingly small in the system size. In this paper, we demonstrate that there is nothing unexpected hidden within the DQC1 model -- Grover's Search, when acting on a mixed state, provably exhibits a speed-up over classical with guarantees as to the presence of only vanishingly small amounts of quantum correlations (entanglement and quantum discord) -- while arguing that this is not an artefact of the oracle-based construction. We also present some important refinements in the evaluation of how much entanglement may be present in DQC1, and how the typical entanglement of the system must be evaluated.

description: Background Pneumonia is the leading infectious cause of hospitalization and death for nursing home (NH) residents; however, diagnosis is often delayed because classic signs of infection are not present. We sought to identify NH residents at high risk for pneumonia, to identify persons to target for more intensive surveillance and preventive measures. Methods Based on a literature review, we identified key risk factors for pneumonia and compiled them for use as prediction tool, limiting risk factors to those available on the Minimum Data Set (MDS). Next, we tested the tool's ability to predict 6-month pneumonia incidence and mortality rates in a sample of 674 residents from 7 NHs, evaluating it both as a continuous and a dichotomous variable, and applying both logistic regression and survival analysis to calculate estimates. Results NH Pneumonia Risk Index scores ranged from −1 to 6, with a mean of 2.1, a median of 2, and a mode of 2. For the outcome of pneumonia, a 1-point increase in the index was associated with a risk odds ratio of 1.26 (P =.038) or a hazard ratio of 1.24 (P =.037); using it as a dichotomous variable (≤2 vs ≥3), the corresponding figures were a risk odds ratio of 1.78 (P =.045) and a hazard ratio of 1.82 (P =.025). For the outcome of mortality, a 1-point increase in the NH Pneumonia Risk Index was associated with a risk odds ratio of 1.58 (P =.002) and a hazard ratio of 1.45 (P =.013); using the index as a dichotomous variable, the corresponding figures were a risk odds ratio of 3.71 (P <.001) and a hazard ratio of 3.29 (P =.001). Conclusions The NH Pneumonia Risk Index can be used by NH staff to identify residents for whom to apply especially intensive preventive measures and surveillance. Because of its strong association with mortality, the index may also be valuable in care planning and discussion of advance directives.

description: DNA condensation by multivalent cations plays a crucial role in genome packaging in viruses and sperm heads, and has been extensively studied using single-molecule experimental methods. In those experiments, the values of the critical condensation forces have been used to estimate the amplitude of the attractive DNA-DNA interactions. Here, to describe these experiments, we developed an analytical model and a rigid body Langevin dynamics assay to investigate the behavior of a polymer with self-interactions, in the presence of a traction force applied at its extremities. We model self-interactions using a pairwise attractive potential, thereby treating the counterions implicitly. The analytical model allows to accurately predict the equilibrium structures of toroidal and rod-like condensed structures, and the dependence of the critical condensation force on the DNA length. We find that the critical condensation force depends strongly on the length of the DNA, and finite-size effects are important for molecules of length up to 10^5 μm. Our Langevin dynamics simulations show that the force-extension behavior of the rod-like structures is very different from the toroidal ones, so that their presence in experiments should be easily detectable. In double-stranded DNA condensation experiments, the signature of the presence of rod-like structures was not unambiguously detected, suggesting that the polyamines used to condense DNA may protect it from bending sharply as needed in the rod-like structures
