description: Recurrence plot based methods are highly efficient and widely accepted tools for the investigation of time series or one-dimensional data. We present an extension of the recurrence plots and their quantifications in order to study recurrent structures in higher-dimensional spatial data. The capability of this extension is illustrated on prototypical 2D models. Next, the tested and proved approach is applied to assess the bone structure from CT images of human proximal tibia. We find that the spatial structures in trabecular bone become more self-similar during the bone loss in osteoporosis.
Il progetto di recupero delle discariche dell'emergenza rifiuti in Campania.

description: Il tema della ricerca effettuata riguarda il progetto di recupero ambientale delle discariche chiuse o in fase di chiusura, in particolare di due discariche aperte durante gli anni dell'emergenza-rifiuti in Campania. La scelta di bonificare questo tipo di aree risponde all 'esigenza di recuperare suolo prezioso e rimpinguare quello sottratto dall'aumento dell'urbanizzazione e dalla costruzione di infrastrutture. Inoltre l'impermeabilizzazione di questi suoli avviene attraverso la copertura del terreno con materiali quali il cemento o l'asfalto, da ciò ne consegue
un grosso rischio ambientale, con effetti tangibili quali le inondazioni, il riscaldamento globale, e minaccia alla biodiversità, soprattutto quando ad essere ricoperti sono i terreni agricoli fertili. La realizzazione di queste superfici impermeabili, proteggendo anche le risorse del suolo, rappresenta una delle grandi sfide ambientali per l'Europa.

description: We analyse the M-theoretic generalisation of the tangent space structure group after reduction of the D=11 supergravity theory to two space-time dimensions in the context of hidden Kac-Moody symmetries. The action of the resulting infinite-dimensional `R symmetry' group K(E9) on certain unfaithful, finite-dimensional spinor representations inherited from K(E10) is studied. We explain in detail how these representations are related to certain finite codimension ideals within K(E9), which we exhibit explicitly, and how the known, as well as new finite-dimensional `generalised holonomy groups' arise as quotients of K(E9) by these ideals. In terms of the loop algebra realisations of E9 and K(E9) on the fields of maximal supergravity in two space-time dimensions, these quotients are shown to correspond to (generalised) evaluation maps, in agreement with previous results of Nicolai and Samtleben (hep-th/0407055). The outstanding question is now whether the related unfaithful representations of K(E10) can be understood in a similar way.

description: We report that Ce doping was achieved in La2CuO4 with the K2NiF4 (T) structure for the first time by molecular beam epitaxy. A synthesis temperature of as low as ~ 630C and an appropriate substrate choice, i.e., (001)LaSrGaO4 (a \~ 3.843 A), enebled us to incorporate Ce into K2NiF4 lattice and to obtain Ce-doped T-La2-xCexCuO4 up to x ~ 0.06. The doping of Ce makes T-La2CuO4 more insulating, which is in sharp contrast to Sr (or Ba) doping in T-La2CuO4, which make the compound metallic and superconducting. The observed smooth increase in resistivity from the hole-doped side (T-La2-xSrxCuO4) to the electron-doped side (T-La2-xCexCuO4) indicates that the electron-hole symmetry is broken in the T-phase materials.

Occupational Exposure Assessment, Metabolism, and Health Effects of Benzene Exposure

description: Benzene is a ubiquitous hydrocarbon that has several natural and anthropogenic sources. When absorbed in the body, benzene is metabolized into toxic intermediates that accumulate in the bone marrow and generate reactive oxygen species. This eventually leads to damage to hematopoietic progenitor cells and culminates in perturbations of hematologic parameters and several types of blood tissue malignancies. This work aimed to examine several aspects of benzene toxicity including occupational exposure, kinetics of metabolism and environmental exposure. Aim 1 of this work established an exposure reconstruction methodology for the Four Refinery Cohort that generated estimate of cumulative exposure. These exposure estimates can be used in future epidemiological investigations to evaluate the health effects of occupational exposure to benzene in a modern context. Aim 2 of this work modelled the dose-response relationship between occupational benzene exposure and the production of metabolites using data from the Shanghai Health Study. The modeled relationships exhibited a clear dose-response with non-linearities that are consistent with enzyme kinetics. The models were further extended to assess whether functional polymorphisms in genes related to benzene metabolism modified the dose-response relationship. These findings further elucidate the kinetics of benzene toxicity which can help to inform benzene regulatory standards and protect workers. Aim 3 of this work evaluated the association between environmental exposure to a mixture of volatile organic chemicals (benzene, toluene, ethylbenzene, xylene, and styrene) and hematologic parameters among a subset of participants in the National Health and Nutrition Examination Survey. We specifically focused on implementing mixture methods to understand the overall health effects of the mixture and to further identify the individual components that are driving these effects. Two mixture methods were used: Bayesian kernel machine regression and quantile g-computation. In sum, this work investigated occupational exposure assessment, molecular mechanisms of benzene toxicity and hematologic manifestations of toxicity to provide an integrated understanding of the health effects of human exposure to benzene. These results can help to inform occupational exposure limits and environmental risk characterization.

description: Accurate waste disposal, at the point of disposal, is crucial to fighting climate change. When materials that could be recycled or composted get diverted into landfills, they cause the emission of potent greenhouse gases such as methane. Current attempts to reduce erroneous waste disposal are expensive, inaccurate, and confusing. In this work, we propose DeepWaste, an easy-to-use mobile app, that utilizes highly optimized deep learning techniques to provide users instantaneous waste classification into trash, recycling, and compost. We experiment with several convolution neural network architectures to detect and classify waste items. Our best model, a deep learning residual neural network with 50 layers, achieves an average precision of 0.881 on the test set. We demonstrate the performance and efficiency of our app on a set of real-world images.

description: Dissipationless collapses in Modified Newtonian Dynamics (MOND) have been studied by using our MOND particle-mesh N-body code, finding that the projected density profiles of the final virialized systems are well described by Sersic profiles with index m<4 (down to m~2 for a deep-MOND collapse). The simulations provided also strong evidence that phase mixing is much less effective in MOND than in Newtonian gravity. Here we describe "ad hoc" numerical simulations with the force angular components frozen to zero, thus producing radial collapses. Our previous findings are confirmed, indicating that possible differences in radial orbit instability under Newtonian and MOND gravity are not relevant in the present context.

Iron line and diffuse hard X-ray emission from the starburst galaxy M82

Publisher: name: arXiv

description: We examine the properties of the diffuse hard X-ray emission in the classic starburst galaxy M82. We use new Chandra ACIS-S observations in combination with reprocessed archival Chandra ACIS-I and XMM-Newton observations. We find E~6.7 keV Fe He-alpha emission is present in the central |r| < 200 pc, |z| < 100 pc of M82 in all datasets at high statistical significance, in addition to a possibly non-thermal X-ray continuum and marginally significant E=6.4 keV Fe K-alpha line emission. No statistically significant Fe emission is found in the summed X-ray spectra of the point-like X-ray sources or the ULX in the two epochs of Chandra observation. The total nuclear region iron line fluxes in the 2004 April 21 XMM-Newton observation are consistent with those of the Chandra-derived diffuse component, but in the 2001 May 6 XMM-Newton observation they are significantly higher and also both E=6.4 and E=6.9 keV iron lines are detected. We attribute the excess iron line emission to the Ultra-Luminous X-ray source in its high state. In general the iron K-shell luminosity of M82 is dominated by the diffuse component. The total X-ray luminosity of the diffuse hard X-ray emission (corrected for emission by unresolved low luminosity compact objects) is L_X ~ 4.4 x 10^39 erg/s in the E=2-8 keV energy band, and the 6.7 keV iron line luminosity is L_X ~ (1.1 -- 1.7) x 10^38 erg/s. The 6.7 keV iron line luminosity is consistent with that expected from the previously unobserved metal-enriched merged supernova ejecta that is thought to drive the larger-scale galactic superwind. The iron line luminosity implies a thermal pressure within the starburst region of P/k ~ 2 x 10^7 K/cm^3, which is consistent with independent observational estimates of the starburst region pressure [Abstract abridged].

description: We study the dynamics of (i) neutral test particles, (ii) magnetically charged test particles, and (iii) test magnetic dipole around a regular Bardeen black hole surrounded by perfect fluid dark matter (PFDM). It has been shown how the magnetic charge of the black hole and the parameter of the surrounding PFDM can influence the innermost stable circular orbit (ISCO) radius of a test particle. We have found that the ISCO radius is strongly affected as a consequence of the combined effect of the magnetic charge parameter and the perfect fluid dark matter. The black hole magnetic charge parameter $g$ and the combined effect of perfect fluid dark matter can mimic the black hole rotation parameter up to $a/M\approx 0.9$. It has been observed that the ISCO for magnetic dipole disappears at the values exceeding the calculated upper value for the magnetic interaction parameter $β$. The upper limit decreases with the increase of both the dark matter and magnetic charge parameters. Finally, as an astrophysical application, we have analyzed degeneracy effects of spin of Kerr black holes and magnetic charge of regular Bardeen black holes for the different values of the dark matter parameter providing exactly the same value for ISCO radius of a magnetic dipole with the same value of the parameter $β=10.2$ of the magnetar called PSR J1745-2900 orbiting around supermassive black hole Sagittarius A*.

description: We investigate how the transport properties of a united atoms fluid with a dissipative particle dynamics thermostat depend on the functional form and magnitude of both the conservative and the stochastic interactions. We demonstrate how the thermostat strongly affects the hydrodynamics, especially diffusion, viscosity, and local escape times. As model system we use SPC water, from which projected trajectories are used to determine the effective interactions in the united atoms model. The simulation results support our argument that the thermostat should be viewed as an integral part of the coarse-grained dynamics, rather than a tool for approaching thermal equilibrium. As our main result we show that the united atoms model with the adjusted effective interactions approximately reproduce the diffusion constant and the viscosity of the underlying detailed SPC water model.

description: We report on the Hopf algebraic description of renormalization theory of quantum electrodynamics. The Ward-Takahashi identities are implemented as linear relations on the (commutative) Hopf algebra of Feynman graphs of QED. Compatibility of these relations with the Hopf algebra structure is the mathematical formulation of the physical fact that WT-identities are compatible with renormalization. As a result, the counterterms and the renormalized Feynman amplitudes automatically satisfy the WT-identities, which leads in particular to the well-known identity $Z_1=Z_2$.

High Frequency Trading Volatility, Market Microstructure Noise and Institutional Investors
Creators: name: Yuting Tan
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: As stocks being traded more intensely daily, many recent studies show that the efficiency and accuracy of some measures developed from low frequency data may not be well guaranteed. It is worth investigating the relationship between institutional investor's behavior and stock return volatility in this new circumstance. We estimate stock return volatility with the two-scales realized volatility (TSRV) estimator which corrects the effect from market microstructure noise on stock prices. Using all transactions of S\&P 500 constituent stocks over the most recent 10 years, we find a positive association between the levels of institutional ownership and daily stock return volatility. This association is not constant over time. Institutional investors are more conservative while the market is more volatile, and they become more aggressive when market calms down. We also analyze quarterly changes in stock return volatility and institutional ownership ratio, and we find evidence that past increase in institutional ownership changes will positively impact the changes in volatility for the future, and past increases in volatility changes will decrease the institutional ownership in the future. But there is no causality relationship between institutional ownership and market microstructure noise. Most institutional investors act similarly except banks. We also find evidence for institutional herding and that stocks with higher institutional ownership ratios attract more high turnover traders, which could be the possible channels through which institutional investors affect stock return volatility.

description: This volume covers Leg 85 of the cruises of the Drilling Vessel Glomar Challenger. When DSDP developed the hydraulic piston corer (HPC), it became possible to recover fairly undisturbed samples from the upper 100 to 300 m and thus to carry out high resolution stratigraphic studies. DSDP Leg 85 was designed to take advantage of this capability. A modified HPC (the VLHPC—variable length hydraulic piston corer) and rotary coring were to be used to recover complete, undisturbed equatorial Pacific sections. The biostratigraphy, magnetostratigraphy, and seismic, carbonate, and stable isotope stratigraphy of these sections were to be studied to develop a better understanding of the paleoceanographic and paleoclimatic history of the region. The JOIDES Ocean Paleoenvironment Panel selected five drill sites that would best address the Leg 85 objectives. Two sites (571 and 572) are in the eastern Pacific, and the three others (573, 574, and 575) form a north-south line that lies at approximately 133°W across the equatorial high productivity zone. The drilling at all five sites was expected to result in the recovery of "reference" sections for the study of foraminifers, nannofossils, radiolarians, diatoms, and other fossils. A secondary objective was to make a detailed examination of the relationships between paleoceanographic changes and the acoustic and physical properties of the sediments. Understanding these relationships could substantially increase the ability to use seismic stratigraphy as a paleoceanographic tool. Another secondary objective was to conduct an in situ heat flow and pore water experiment to study pore water advection in a region of unusually low heat flow (Site 571). Leg 85 began in Los Angeles, California in March 1982 and ended in Honolulu, Hawaii in April 1982.

description: We describe a homogeneous catalog compilation of common proper motion stars based on Gaia DR2. A preliminary list of all pairs of stars within the radius of 100 pc around the Sun with a separation less than a parsec was compiled. Also, a subset of comoving pairs, wide binary stars, was selected. The clusters and systems with multiplicity larger than 2 were excluded from consideration. The resulting catalog contains 10358 pairs of stars. The catalog selectivity function was estimated by comparison with a set of randomly selected field stars and with a model sample obtained by population synthesis. The estimates of the star masses in the catalogued objects, both components of which belong to the main-sequence, show an excess of "twins", composed by stars with similar masses. This excess decreases with increasing separation between components. It is shown that such an effect cannot be a consequence of the selectivity function only and does not appear in the model where star formation of similar masses is not artificially preferred. The article is based on the talk presented at the conference "Astrometry yesterday, today, tomorrow" (Sternberg Astronomical Institute of the Moscow State University, October 14-16, 2019).

description: The lateral Casimir force is employed to propose a design for a potentially wear-proof rack and pinion with no contact, which can be miniaturized to nano-scale. The robustness of the design is studied by exploring the relation between the pinion velocity and the rack velocity in the different domains of the parameter space. The effects of friction and added external load are also examined. It is shown that the device can hold up extremely high velocities, unlike what the general perception of the Casimir force as a weak interaction might suggest.

3D Spheroidal Human Liver Models for Drug Toxicity Testing

description: Drug-induced liver injury (DILI) remains the leading cause of preclinical and clinical drug attrition, drug withdrawals from the market, and black-box warnings on currently marketed drugs. This study aims to provide an efficient model to predict drug-induced hepatotoxicity through optimization of a widely used three-dimensional liver model system, namely spheroids. Addressing the different rates of formation of monoculture spheroids, we evaluated the role of coculture with primary human hepatocytes by adding relevant cell types demonstrating differences in functionality and spheroid formation. We also assessed drug sensitivity of all the culture conditions using known toxic and non-toxic pharmaceutical drugs, providing a comprehensive comparison between different types of spheroids. Our results suggest that different monoculture spheroids formation rates can be mitigated using a coculture model system with few limitations related to drug sensitivity. Lastly, we fabricated microwells using poly (ethylene glycol) diacrylate (PEGDA), which is considered a cytocompatible and easy to use polymer, on a glass substrate with the aim of multiple spheroid formation per well in a 96 well plate and enabling full media changes that reduces handling time of the cultures. The results suggest consistent spheroid formation with a detectable level of functions for all culture conditions, enabling future use of the model system for many applications, including drug screening.
Meaning and process in experiential education: the wilderness expedition as a rite of passage
Creators: name: Andrews, Kenneth Brian
Publisher: name: University of British Columbia
Year: 2009

description: This paper explores the wilderness expedition as a personal rite of passage - as a process of transition from society through liminality and back to society again. Through analytical discussions interwoven with narrative-descriptive passages and extensive quotations from expedition participants, this anthropological study of the wilderness expedition illuminates the underlying process of separation, transition/liminality, and reincorporation, focusing upon, as Victor Turner suggests, the meaningful experiences of personal transformation embedded within the liminal (or transitional) phase. Examining the expedition as a quintessential form of experiential education, we begin with the question: 'what do students learn from the expedition experience?' 'what do they come to know?'. Beneath all the explicit lessons in outdoor skills, natural history, leadership, and teamwork, participants also come to know an intense experience of communitas - a sense of self, a sense of community, and a sense of place - from which they return to society empowered by renewed creative energy, an expanded worldview, and a greater sense of hope.

The supersolid state is characterized by a coexistence of crystalline order and superfluidity. Using a quantum Monte Carlo method based on the directed-loop algorithm, we calculate static structure factors and superfluid density at finite temperature, from which we obtain the phase diagram. The supersolid phase exists at intermediate fillings between a three-quarter-filled solid phase and a half-filled solid phase. We also discuss the mechanism of the supersolid state on the FCC lattice.

description: Una delle questioni più rilevanti, in seguito all'evoluzione culturale, organizzativa ed operativa delle modalità assistenziali, riguarda il ruolo dell'ospedale e la funzione ospedaliera di cura e di riabilitazione all'interno del sistema dei servizi sanitari. Da un lato, grazie alla ricerca e alla tecnologia, è possibile ricevere cure avanzate, usare presidi e rimedi sofisticati, dall'altro è cresciuta moltissimo la popolazione anziana con problemi di salute cronici, che necessitano di essere seguiti nel tempo, più che di un intervento urgente ed immediato.
L'evoluzione in atto porta l'ospedale a trasformarsi da grande e indifferenziato luogo di degenza e assistenza a struttura di dimensioni medio-piccole ad alto contenuto tecnologico e scientifico, in grado di erogare un consistente numero di prestazioni di elevata complessità, differenziate e concentrate in periodi temporali molto limitati.
L'ospedale, quindi, tende a spostarsi progressivamente sulle attività di trattamento diurno (day hospital e day surgery) e ambulatoriale, con una significativa attività di raccordo con il territorio, finalizzata a garantire la continuità assistenziale. La messa in rete degli ospedali, dunque, è uno strumento utile per garantire a tutti i cittadini equità di accesso a prestazioni e servizi sanitari efficaci ed appropriati in un contesto di risorse limitate.
La creazione di una rete ospedaliera significa, quindi, riorganizzare tutte le risorse ospedaliere per attività assistenziali utili al bacino di utenza, favorendo le economie di scala e l'appropriatezza delle cure, in una logica d'interdipendenza con le strutture di riferimento dei secondo livello.
Per analizzare le problematiche relative alla progettazione di una rete ospedaliera in grado di supportare il cambiamento richiesto dalla politiche comunitarie, si è partiti dall'analisi del design propria del sistema manifatturiero/produttivo, ovvero dall'analisi del Supply Netwok, l'applicabilità dei principi del Supply Chain Management oltre che al manufacturing anche all'ambito dei servizi.

description: The ability to shuttle coherently individual electron spins in arrays of quantum dots is a key procedure for the development of scalable quantum information platforms. It allows the use of sparsely populated electron spin arrays, envisioned to efficiently tackle the one- and two-qubit gate challenges. When the electrons are displaced in an array, they are submitted to site-dependent environment interactions such as hyperfine coupling with substrate nuclear spins. Here, we demonstrate that the electron multi-directional displacement in a $3\times 3$ array of tunnel coupled quantum dots enhances the spin coherence time via the motional narrowing phenomenon. More specifically, up to 10 configurations are explored by the electrons to study the impact of the displacement on spin dynamics. An increase of the coherence time by a factor up to 10 is observed in case of fast and repetitive displacement. The physical mechanism responsible for the loss of coherence induced by displacement is quantitatively captured by a simple model and its implications on spin coherence properties during the electron displacement are discussed in the context of large-scale quantum circuits.

description: Alcohol use disorder (AUD) is a difficult disorder to treat. Identifying relevant signaling pathways in the brain may be useful for finding new pharmacological targets to treat AUD. The receptor tyrosine kinase ALK activates the transcription factor STAT3 in response to ethanol exposure in vitro. Here, we demonstrate ALK activation and upregulation of known STAT3 target genes (Socs3, Gfap, and Tnfrsf1a) in the prefrontal cortex (PFC) and ventral hippocampus (vHPC) of mice after 4 days of binge-like ethanol drinking. To investigate the behavioral relevance of activated STAT3, we treated mice with a STAT3 inhibitor, stattic, and observed that they drank less ethanol compared with vehicle-treated mice. Finally, to identify novel ethanol-induced target genes downstream of ALK-STAT3, we analyzed the NIH LINCS L1000 database for gene signature overlap between ALK inhibitor (alectinib and NVP-TAE684) and STAT3 inhibitor (niclosamide) treatments on cell lines. This signature was then compared to genes that were differentially expressed in the PFC of mice after binge-like drinking. We found 95 unique gene candidates and examined them for STAT3 binding motifs in their promoters. Fifty-seven of the 95 genes had STAT3 motifs. We validated by qPCR that expression of putative STAT3 target genes Nr1h2, Smarcc1, Smarca4, and Gpnmb were increased in the PFC or vHPC after binge-like drinking. Together these results demonstrate activation of the ALK-STAT3 signaling pathway in the brain after binge-like ethanol consumption, identify putative novel ethanol-responsive STAT3 target genes, and suggest that STAT3 inhibition may be a potential method to reduce binge drinking in humans.

description: Physical reservoir computing is a type of recurrent neural network that applies the dynamical response from physical systems to information processing. However, the relation between computation performance and physical parameters/phenomena still remains unclear. This study reports our progress regarding the role of current-dependent magnetic damping in the computational performance of reservoir computing. The current-dependent relaxation dynamics of a magnetic vortex core results in an asymmetric memory function with respect to binary inputs. A fast relaxation caused by a large input leads to a fast fading of the input memory, whereas a slow relaxation by a small input enables the reservoir to keep the input memory for a relatively long time. As a result, a step-like dependence is found for the short-term memory and parity-check capacities on the pulse width of input data, where the capacities remain at 1.5 for a certain range of the pulse width, and drop to 1.0 for a long pulse-width limit. Both analytical and numerical analyses clarify that the step-like behavior can be attributed to the current-dependent relaxation time of the vortex core to a limit-cycle state. }

description: IGBTs are the most preferred power devices in medium power and frequency applications. Due to rapid developments of  IGBT technology, the need of more accurate and reliable compact models within circuit simulators has become crucial for both device and circuit designers. Thus, an improved and optimized version of the Kraus NPT IGBT model has been developed and implemented within PSpice OrCad environment. The enhancements brought to the model have regarded the addition of some IGBT typical features such as PiN injection effect or avalanche breakdown as well as the definition of temperature dependencies of semiconductor physical constants to make model suitable for electro-thermal simulations. An automated parameters calibration procedure, based on curve-fitting method and implemented in MATLAB environment, has been proposed for definition of model parameters. Hence, the ET model has been validated by comparing simulation results with experimental measurements performed on laboratory test circuits of three different application scenarios. Finally, the Kraus model has been extended to modern Field-Stop IGBT technology  by implementing in PSpice the approximated equations of FS layer.

description: In recent years, thanks to the ICT systems, there has been a continued growth and an increasing accumulation of the available information. Managing information has become one of the key activities in any sector. Indeed, information management emerged as the core and the basis of manufacturing enterprise. The research activity mainly focused on the development of a Knowledge Based Engineering (KBE) methodology for supporting a manufacturing company, in particular railway manufacturers, in reusing company knowledge. A Decision Support System (DSS) has been developed with the scope of identifying products already designed that fully or partly fit what required by new bids. The DSS has been built within a PLM software and part of the research has concentrated on comparing the PLM suites available in the market searching for the best tool able to act the role of a centralized management dashboard for knowledge reuse. The proposed methodology involves different business units and several expertise, emphasizing the importance of a collaborative environment and the need of a methodology for design review sessions.
Contents of this thesis retrace these considerations: the second chapter reports a technology scouting on the available PLM tools; the third and the fourth chapters deal with a KBE methodology and the development of a DSS; the fifth one proposes the development of an immersive virtual reality environment aimed at deploying review sessions by design and manufacturing teams with interdisciplinary skills; at last, in the sixth chapter, it is reported a Discrete Event Simulation application as example of a procedural KBE application.

description: A MHz gravitational wave search for harmonic sources was conducted using a 704-hr dataset obtained from the Holometer, a pair of 40-meter power recycled Michelson interferometers. Our search was designed to look for cosmic string loops and eccentric black hole binaries in an entirely unexplored frequency range from 1 to 25 MHz. The measured cross-spectral density between both interferometers was used to perform four different searches. First, we search to identify any fundamental frequencies bins that have excess power above 5$σ$. Second, we reduce the per-bin threshold on any individual frequency bin by employing that a fundamental frequency and its harmonics all collectively lie above a threshold. We vary the number of harmonics searched over from $n= 4$ up to $n=23$. Third, we perform an agnostic approach to identify harmonic candidates that may have a single contaminated frequency bin or follow a power-law dependence. Lastly, we expand on the agnostic approach for individual candidates and search for a potential underlying population of harmonic sources. Each method was tested on the interferometer dataset, as well as a dark noise, photon shot-noise-limited, and simulated Gaussian-noise datasets. We conclude that these four different search methods did not find any candidate frequencies that would be consistent with harmonic sources. This work presents a new way of searching for gravitational wave candidates, which allowed us to survey a previously unexplored frequency range.

description: A mouse model of human acute myelogenous leukemia (AML) was achieved using 400 cgy of total body irradiation of low dose 137-Cesium radiation (1.48 Rads/min.) to Scid mice which were injected intravenously with human AML cells. Demonstrated engraftment in mice of an AML cell line, M07eJ-IL-3, which harbours a retroviral construct producing human IL-3 and neomycin (G418) resistance, was determined by Southern analysis of mouse tissues for human DNA and G418 resistance of cells from mouse tissues. Nine AML peripheral blood patient samples were intravenously injected into mice following 400 cgy radiation and subsequent injections of 6 ug human interleukin-3 (IL-3) and 10 ug stem cell factor (SCF) intraperitoneally every other day. Five out of 9 patients samples engrafted in the Scid mice as assessed by DNA analysis using a human specific HERV-H probe, May-Grunwald Giemsa staining for leukemic cell morphology in mouse tissues and fluorescence in situ hybridization (FISH) for cytogenetic abnormalities in the patients. Scid-hu patient #8 demonstrated high levels of engraftment . in the bone marrow 4 weeks post injection while later time points demonstrated dissemination of the human cells in to the bone marrow, spleen, peripheral blood and tumours. These results suggest that there is heterogeneity in the degree to which patient samples will engraft if at all. This model may aid the studies of the AML stem cell biology and be useful for preclinical studies of novel therapies for this disease.

description: Pasta is a traditional wheat-based food, whose popularity, indisputable in Italy and progressive in Europe as well as in America and in the East, is essentially due to the nutritional and sensory qualities that have made it an attractive source of carbohydrates, enviable and difficult to replace in a healthy and balanced diet. The overall pasta quality is highly influenced by raw materials and production technologies. As far as the raw material, the protein content and the gluten quality of semolina are crucial factors in achieving good texture and cooking performance of the final product. Among the technological processes, the drying step is the most delicate and important The aim of the thesis was to evaluate the effect of raw material, technological processes and cooking methods on pasta quality.  The work is split into three cases study. The object of first case study was to evaluate the effect of semolina from both mono-varietal and commercial mix durum wheat on qualitative characteristics of dry pasta; moreover, for each semolina was conducted a study on the effects of high and very high drying temperature on final product in order to assess if and how drying method could affect pasta. Six monovarietal semolina and two commercial mix were used to produce spaghetti than subjected to drying according to two different drying cycles: high temperature (75 ° C) and very high temperature (90 ° C) drying cycles thus obtaining a total of sixteen samples, two for each semolina sample. In the second case study, was evaluated the cooking quality of alternative cooked pasta with the purpose to understand which may be the best (reducing time and /or energy) alternatives to traditional cooking. Four different hollow shapes coming from the same production lot were used; pasta sample were than underwent to passive cooking and microwave cooking. Pasta quality was evaluated by means of sensory, physical and structural analysis by using traditional cooking as reference
Finally the third study aimed to asses the influence of chickpea flour and microwave drying operation on starch digestibility and glycemic index of composite legume-wheat pasta.  A substitution of 20% chickpea flour was made with respect to the reference sample (100% semolina). Six pasta samples were prepared from 100% semolina, semolina (80%) and raw chickpea flour (20%), semolina (80%) and cooked chickpea flour; each sample was than subjected to traditional drying (40°C; RH 80%) and an optimized microwave drying.. The results showed that chemical, physical, and sensory analysis were all very sensitive to changes in pasta quality.
Raw material, process operations and cooking influenced the qualitative characteristics of pasta.
The addition of different ingredients in pasta improved the nutritional characteristics of final product. The use of new technologies of drying brought advantages in terms of reduction of time and cost.
