description: Machine learning has endless applications in the health care industry. White blood cell classification is one of the interesting and promising area of research. The classification of the white blood cells plays an important part in the medical diagnosis. In practise white blood cell classification is performed by the haematologist by taking a small smear of blood and careful examination under the microscope. The current procedures to identify the white blood cell subtype is more time taking and error-prone. The computer aided detection and diagnosis of the white blood cells tend to avoid the human error and reduce the time taken to classify the white blood cells. In the recent years several deep learning approaches have been developed in the context of classification of the white blood cells that are able to identify but are unable to localize the positions of white blood cells in the blood cell image. Following this, the present research proposes to utilize YOLOv3 object detection technique to localize and classify the white blood cells with bounding boxes. With exhaustive experimental analysis, the proposed work is found to detect the white blood cell with 99.2% accuracy and classify with 90% accuracy.

description: We present the results of a new spectroscopic and photometric survey of the hot, binary X-ray cluster A115 at z=0.193, containing a radio relic. We combine galaxy velocity and position information to select 85 galaxies recognized as cluster members (from 115 galaxies observed at TNG telescope), determine global dynamical properties and detect substructures. We find that A115 presents velocity dispersion of sigma_v=1362_{-108}^{+126} km/s. Our analysis confirms the presence of two structures (A115N and A115S) of cluster--type well recognizable in the plane of the sky and shows that they differ of ~2000 km/s in the LOS velocity. We estimate that A115S is slightly dynamically more important than A115N having sigma_v=900-1100 km/s vs sigma_v=750-850 km/s. Moreover, we find evidence for two small groups at low velocities. We estimate a global cluster virial mass of 2.2--3.5 e15 h_70 Msun. Our results agree with a pre--merging scenario where A115N and A115S are colliding with a LOS impact velocity Delta v~1600 km/s.The most likely solution to the two--body problem suggests that the merging axis lies at $\sim 20$ degrees from the plane of the sky and that the cores will cross after ~0.1 Gyr. The radio relic with its largest dimension perpendicular to the merging axis is likely connected to this merger.

PETALO: a Time-of-Flight PET with liquid xenon

Subjects: subject: Instrumentation and Detectors (physics.ins-det)
subject: FOS: Physical sciences

description: Liquid xenon offers several features, which make it suitable for applications in nuclear medicine, such as high scintillation yield and fast scintillation decay time. Moreover, being a continuous medium with a uniform response, liquid xenon allows one to avoid most of the geometrical distortions of conventional detectors based on scintillating crystals. In this paper, we describe how these properties have motivated the development of a novel concept for positron emission tomography scanners with Time-Of-Flight measurement, which combines a liquid xenon scintillating volume and silicon photomultipliers as sensors. A Monte Carlo investigation has pointed out that this technology would provide an excellent intrinsic time resolution, down to 70 ps. Also, the transparency of liquid xenon to UV and blue wavelengths opens the possibility of exploiting both scintillation and Cherenkov light for a high-sensitivity positron emission tomography scanner with Time-Of-Flight capabilities. Monte Carlo simulations point to a time resolution of 30-50 ps obtained using Cherenkov light. A prototype is being built to demonstrate the high resolution in energy, time and reconstruction of spatial coordinates of this concept, using a ring of 30 cm internal diameter and a depth of 3 cm instrumented with VUV-sensitive silicon photomultipliers.

description: Dephasing is a ubiquitous phenomenon that leads to the loss of coherence in quantum systems and the corruption of quantum information. We present a universal dynamical control approach to combat dephasing during all stages of quantum computation, namely, storage, single- and two-qubit operators. We show that (a) tailoring multi-frequency gate pulses to the dephasing dynamics can increase fidelity; (b) cross-dephasing, introduced by entanglement, can be eliminated by appropriate control fields; (c) counter-intuitively and contrary to previous schemes, one can increase the gate duration, while simultaneously increasing the total gate fidelity.

Systematic Errors in Sunyaev-Zeldovich Surveys of Galaxy Cluster Velocities

description: Galaxy cluster surveys compiled via the Sunyaev-Zeldovich Effect have the potential to place strong constraints on cosmology, and in particular the nature of dark energy. Here we consider cluster velocity surveys using kinetic Sunyaev-Zeldovich measurements. Cluster velocities closely trace the large-scale velocity field independent of cluster mass; we demonstrate that two useful cluster velocity statistics are nearly independent of cluster mass, in marked contrast to cluster number count statistics. On the other hand, cluster velocity determinations from three-band observations of Sunyaev-Zeldovich distortions can require additional cluster data or assumptions, and are complicated by microwave emission from dusty galaxies and radio sources, which may be correlated with clusters. Systematic errors in velocity due to these factors can give substantial biases in determination of dark energy parameters, although large cluster velocity surveys will contain enough information that the errors can be modeled using the data itself, with little degradation in cosmological constraints.

description: The evaluation of question answering models compares ground-truth annotations with model predictions. However, as of today, this comparison is mostly lexical-based and therefore misses out on answers that have no lexical overlap but are still semantically similar, thus treating correct answers as false. This underestimation of the true performance of models hinders user acceptance in applications and complicates a fair comparison of different models. Therefore, there is a need for an evaluation metric that is based on semantics instead of pure string similarity. In this short paper, we present SAS, a cross-encoder-based metric for the estimation of semantic answer similarity, and compare it to seven existing metrics. To this end, we create an English and a German three-way annotated evaluation dataset containing pairs of answers along with human judgment of their semantic similarity, which we release along with an implementation of the SAS metric and the experiments. We find that semantic similarity metrics based on recent transformer models correlate much better with human judgment than traditional lexical similarity metrics on our two newly created datasets and one dataset from related work.

description: Turbulence generally arises in shear flows if velocities and hence inertial forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit disordered motion even at vanishing inertia. Intermediate between these cases, a novel state of chaotic motion, `elasto-inertial turbulence' (EIT), has been observed in a narrow Reynolds number interval. We here determine the origin of EIT in experiments and show that characteristic EIT structures can be detected across an unexpectedly wide range of parameters. Close to onset a pattern of chevron shaped streaks emerges in excellent agreement with linear theory. However, the instability can be traced to far lower Reynolds numbers than permitted by theory. For increasing inertia, a secondary instability gives rise to a wall mode composed of inclined near wall streaks and shear layers. This mode persists to what is known as the `maximum drag reduction limit' and overall EIT is found to dominate viscoelastic flows across more than three orders of magnitude in Reynolds number.
The protective effect of beta-carotene and vitamin A on genotoxicity and cytotoxicity of dimethylnitrosamine in vitamin A-deficient rats
Creators: name: Yee, Gina
Publisher: name: University of British Columbia
Year: 2010

description: Epidemiological evidence and chemopreventive trials point to an antimutagenic and anticarcinogenic role for retinoids and carotenoids. Studies on human populations are logistically difficult and often ethically unacceptable. Therefore, to gain information on the potential chemopreventive benefits of dietary vitamin A and beta-carotene, the following experimental model was used. Rats were made vitamin A (retinol) deficient, then exposed to the liver carcinogen dimethylnitrosamine (DMN), partially hepatectomized, and thereafter, examined for the extent of liver necrosis (cytotoxicity) and the frequency of anaphase and telophase cells with chromosomal fragments, chromatin bridges and micronuclei (genotoxicity). Vitamin A-deficient rats (serum retinol levels <2 0 ng/ml and liver retinol levels <43 ng/g tissue) showed increased sensitivity towards the cytotoxic and genotoxic action of DMN as compared to vitamin A-fed dietary control rats. This elevated sensitivity was abolished by supplementation of the vitamin A-deficient diet with beta-carotene (10 mg/kg diet) or with vitamin A (2 mg/kg diet) prior to DMN exposure. However, vitamin A feeding at higher doses (16 mg/kg diet), which led to an excessive accumulation of retinol in the liver (>25,000 ng/g tissue), resulted in an accentuation of the necrotic and genotoxic action of DMN when high doses (35 mg/kg body weight) were administered. The results show that vitamin A deficiency leads to an increased susceptability to DMN-induced damage. Dietary supplementation with beta-carotene and with vitamin A (at adequate levels) protected against the deleterious effects of DMN, but supplementation with vitamin A at excessive levels potentiated the action of the carcinogen. This divergent, dose-dependent action of vitamin A calls for caution in the design of intervention strategies.

description: This article reports about a novel extension of dissipative particle dynamics (DPD) that allows the study of the collective dynamics of complex chemical and structural systems in a spatially resolved manner with a combinatorially complex variety of different system constituents. We show that introducing multipolar interactions between particles leads to extended membrane structures emerging in a self-organized manner and exhibiting both the necessary mechanical stability for transport and fluidity so as to provide a two-dimensional self-organizing dynamic reaction environment for kinetic studies in the context of cell biology. We further show that the emergent dynamics of extended membrane bound objects is in accordance with scaling laws imposed by physics.

data governance

description: Data sharing has existed in specific sectors and contexts for many decades, although limited by the amount of data available and the number of players involved. New technologies and digitisation have dramatically increased the type and volume of data available. The capability to collect and analyse static and real-time data, along with reduced storage and processing costs, has opened up the potential to create significant new value within and across public and private sectors.

This research explores how groups of organisations have come together to share personal and non-personal data, and the various components that have enabled the delivery of trusted data sharing solutions. It is relevant to public- and private-sector organisations that have identified the opportunity to create value through sharing data and wish to collaborate with others to develop solutions. Policymakers in government and other stakeholders who play a role in promoting the many opportunities and developing enablers for data sharing across many organisations or across industry sectors may also find this research useful.

description: The ringdown of a perturbed black hole contains fundamental information about space-time in the form of Quasi Normal Modes (QNM). Modifications to general relativity, or extended profiles of other fields surrounding the black hole, so called "black hole hair", can perturb the QNM frequencies. Previous works have examined the QNM frequencies of spherically symmetric "dirty" black holes - that is black holes surrounded by arbitrary matter fields. Such analyses were restricted to static systems, making the assumption that the metric perturbation was independent of time. However, in most physical cases such black holes will actually be growing dynamically due to accretion of the surrounding matter. Here we develop a perturbative analytic method that allows us to compute for the first time the time dependent QNM deviations of such growing dirty black holes. Whilst both are small, we show that the change in QNM frequency due to the accretion can be of the same order or larger than the change due to the static matter distribution itself, and therefore should not be neglected in such calculations. We present the case of spherically symmetric accretion of a complex scalar field as an illustrative example, but the method has the potential to be extended to more complicated cases.

description: This case study outlines the steps Oatly has taken so far to achieve its goal of becoming the largest ‘dairy and milk’ producer in the world. Oatly develops, produces and markets dairy and milk analogues, with an overriding ambition to promote structural changes in the dairy industry. Oatly’s approach relies on state-of-the-art technologies that can create dairy analogues and milk-like fluids. The resulting products are marketed under their own brand and promoted by provocative and innovative communication strategies that include storytelling, policy-related activities, social media campaigns and more traditional sales concepts. The company is constantly developing and opening factories that enable them to expand into foreign markets, whilst applying diverse marketing strategies. Following Oatly’s example, other retailers and food companies also expressed their interest in dairy and milk replacement products, increasing the market competition.

description: Exoplanets on eccentric orbits experience an incident stellar flux that can be markedly larger at periastron versus apoastron. This variation in instellation can lead to dramatic changes in atmospheric structure in regions of the atmosphere where the radiative and advective heating/cooling timescales are shorter than the orbital timescale. To explore this phenomenon, we develop a sophisticated one-dimensional (vertical) time-stepping atmospheric structure code, EGP+, capable of simulating the dynamic response of atmospheric thermal and chemical structure to time-dependent perturbations. Critically, EGP+ can efficiently simulate multiple orbits of a planet, thereby providing new opportunities for exoplanet modeling without the need for more computationally-expensive models. We make the simplifying assumption of cloud-free atmospheres, and apply our model to HAT-P-2b, HD~17156b, and HD~80606b, which are known to be on higher-eccentricity orbits. We find that for those planets which have Spitzer observations, our planet-to-star ratio predictions are roughly consistent with observations. However, we are unable to reproduce the observed peak offsets from periastron passage. Finally, we discuss promising pathways forward for adding new model complexity that would enable more detailed studies of clear and cloudy eccentric planets as well as worlds orbiting active host stars.

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2011

description: In this thesis we describe the efforts we made for designing, developing and
analyzing new routing and channel assignment algorithms for wireless mesh
networks. In particular we discuss about a new channel re-assignment scheme,
able to minimize the number of changes required to accomodate  new traffic
demands, a new MPLS-based forwarding paradigm, resistant to
failures and able to cope with variations of the traffic demands and, finally, a
new forwarding paradigm able to exploit aggregation opportunities at the MAC
layer.

Before going into the details of these new algorithms, we introduce some of the
networking testbeds, platforms and tools we have leveraged for their
evaluation. We also describe a contribution we have made in the field of
heterougeneous networking testbeds, in particular regarding the integration of
local wireless mesh testbeds in PlanetLab.

description: We describe a strategy for scheduling astrometric observations to minimize the number required to determine the mutual orbits of binary transneptunian systems. The method is illustrated by application to Hubble Space Telescope observations of (42355) Typhon-Echidna, revealing that Typhon and Echidna orbit one another with a period of 18.971 +/- 0.006 days and a semimajor axis of 1628 +/- 29 km, implying a system mass of (9.49 +/- 0.52) x 10^17 kg. The eccentricity of the orbit is 0.526 +/- 0.015. Combined with a radiometric size determined from Spitzer Space Telescope data and the assumption that Typhon and Echidna both have the same albedo, we estimate that their radii are 76 +14/-16 and 42 +8/-9 km, respectively. These numbers give an average bulk density of only 0.44 +0.44/-0.17 g cm^-3, consistent with very low bulk densities recently reported for two other small transneptunian binaries.
Analisi molecolare e correlazione genotipo-fenotipo in pazienti con deficit di Antitrombina dell’Italia Meridionale

description: Abbiamo sequenziato il gene SERPINC 1 in 26 pazienti (15F, 11 M) con deficit di Antitrombina (22 tipo I, 4 tipo II), appartenenti a 18 diverse famiglie, tra loro  non imparentate, tutte provenienti dall’Italia meridionale. Mutazioni in eterozigosi sono state identificate in 15 famiglie su 18 (83.3%). Tra queste 8 erano mutazioni “novel”, cioè di nuovo riscontro e dunque mai descritte prima in letteratura. 7 mutazioni chiaramente portavano ad un’alterata sintesi proteica (4 frameshift, 1 non-stop, 1 mutazione di splicing e 1 con delezione di 21 paia di basi). Una mutazione, presente in un singolo paziente, era una mutazione missense che sembra essere la causa del deficit di AT  perché: a) è assente in 100 cromosomi nei controlli; b) essa coinvolge un aminoacido altamente conservato la cui sostituzione si pensa che possa alterare l’attività antitrombinica; c) nessuna altra mutazione è stata identificata nel paziente in questione.
Mutazioni gravi (es. nonsense, frameshift, delezioni) sono state evidenziate nei pazienti con deficit di AT di tipo I. Al contrario, nei pazienti con deficit di AT di tipo II, 3 mutazioni su 4 erano di tipo missense; la quarta mutazione identificata portava ad uno shift di 19 nucelotidi nel codone di stop.
In aggiunta al tipo di mutazione riscontrata, la coesistenza con altri fattori di rischio predisponenti aiuta a comprendere la severità del quadro clinico nei pazienti con deficit di tipo I (età del primo evento,  rischio di recidive durante la profilassi).
Nelle 5 famiglie in cui vi era più di un componente affetto, è stato osservato lo stesso genotipo e un’espressione clinica concordante.
Possiamo concludere che le basi molecolari del deficit di AT nel Sud Italia sono diverse se comparate ad altre aree geografiche, e che l’analisi molecolare e lo studio degli effetti della mutazione sul fenotipo possono aiutare a predire l’espressione clinica della malattia.

description: In this paper, we first use semi-classical methods to study quantum field theoretical aspects of the integrable noncommutative sine-Gordon model proposed in [hep-th/0406065]. In particular, we examine the fluctuations at quadratic order around the static kink solution using the background field method. We derive equations of motion for the fluctuations and argue that at O(theta^2) the spectrum of fluctuations remains essentially the same as that of the corresponding commutative theory. We compute the one-loop two-point functions of the sine-Gordon field and the additional scalar field present in the model and exhibit logarithmic divergences, only some of which lead to UV/IR mixing. We briefly discuss the one-loop renormalization in Euclidean signature and comment on the obstacles in determining the noncommutativity corrections to the quantum mass of the kink.

La scrittura teorica e critica di Gian Pietro Lucini.

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2011

description: Gian Pietro Lucini, poeta e scrittore lombardo vissuto tra la fine dell'Ottocento e i primi anni del Novecento, svolse un'intensa attività di teorico e critico della letteratura. Egli si confrontò infatti con le più importanti esperienze artistiche di inizio secolo, dall'Avanguardia Futurista all'importante dibattito sulla liberazione dalla metrica tradizionale che portò all'affermazione del verso libero in Italia. Egli si scontrò con Marinetti sui temi di novità e tradizione che segnarono in lui il rifiuto dell'Avanguardia in senso distruttivo ed iconoclasta e l'accettazione di un Modernismo più incline alla conservazione di una tradizione invecchiata. Da un punto di vista formale, invece, Lucini lascia al nuovo secolo l'innovazione tecnica del verso libero, unico metro in grado di adattarsi al mutato contesto storico-culturale e alla diversa sensibilità dei poeti novecenteschi.
Lucini si trovò anche a fare i conti con la tradizione letteraria più prossima, rappresentata da Carlo Dossi e Gabriele D'Annunzio, e con quella ottocentesca, rappresentata dal Foscolo didimeo. Inoltre le sue numerose e fitte recensioni ad autori contemporanei non solo italiani fanno luce sulle questioni letterarie più dibattute in quegli anni e sui poeti che meglio incarnavano la nuova temperie culturale. Tuttavia, la rivoluzione operata da Lucini nel campo delle lettere fu di ordine più teorico che pratico, in quanto le sue anticipazioni, intuizioni ed innovazioni costituiscono una preziosa eredità lasciata al Novecento che, tramite personalità successive, porterà a compimento nella reale prassi letteraria ciò che Lucini aveva solo teorizzato.

description: Rabies continues to be a major and much-feared hazard to public health in the 21st century. The disease, which is brought on by neurotropic viruses of the genus Lyssavirus, manifests as a progressive and always deadly encephalomyelitis under treatment. As per Fooks and Jackson (2020), the rabies virus (RABV) is a member of the family Rhabdoviridae, which comprises viruses in the shape of bullets, the genus Lyssavirus, and the order Mononegavirales, which comprises viruses with non-segmented, negative-stranded RNA genomes. Based on preliminary statistics, it appears that rabies causes almost 60,000 deaths worldwide each year, more than any other zoonotic disease combined. The most common way for rabies to spread among animals is by animal bites, although it can also be contracted through licks, scratches, or the infecting of mucosa or open wounds with saliva Nearly all human instances of rabies are transmitted by dogs, who serve as the primary vector for the disease. Therefore, the first line of defense against human rabies is to control rabies in dogs, particularly in stray or free-roaming dogs (Meslin and Briggs, 2013). The World Organization for Animal Health (WOAH), formerly known as the OIE, the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) partnered with the Global Alliance for Rabies Control (GARC) under the United Against Rabies Forum (Tidman et al., 2022) to launch Zero by 30, the Global Strategic Plan to End Human Deaths from Dog-mediated Rabies by 2030.

description: Many systems of scientific interest can be conceptualized as multipartite networks. Examples include the spread of sexually transmitted infections, scientific collaborations, human friendships, product recommendation systems, and metabolic networks. In practice, these systems are often studied after projection onto a single class of nodes, losing crucial information. Here, we address a significant knowledge gap by comparing transmission dynamics on temporal multipartite networks and on their time-aggregated unipartite projections to determine the impact of the lost information on our ability to predict the systems' dynamics. We show that the dynamics of transmission models can be dramatically dissimilar on multipartite networks and on their projections at three levels: final outcome, the magnitude of the variability from realization to realization, and overall shape of the temporal trajectory. We find that the ratio of the number of nodes to the number of active edges over the time aggregation scale determines the ability of projected networks to capture the dynamics on the multipartite network. Finally, we explore which properties of a multipartite network are crucial in generating synthetic networks that better reproduce the dynamical behavior observed in real multipartite networks.

description: The purpose of this work is to rewrite the equations of motion such that even third-class trajectories can be optimized with the current parameter optimization methods. At first the commonly used coordinate systems and Euler angles are presented in Section II. It will be realized that the definition of the Euler angles introduces additional singularities. A short derivation of the commonly-used equations of motion follows for comparison and better understanding of the later derived sets of equations of motion. Section II closes with a reduction of the optimal control problem to a parameter optimization problem. Some characteristic properties and assumptions of the parameter optimization problem are pointed out along with the necessary equations and conditions needed to solve it. Section III introduces several methods that allow integration of second- and third-class trajectories as long as some restrictions are imposed on the allowable trajectories. The first method is the so-called inertial-acceleration method. It is based on the idea that the velocity yaw angle and the velocity pitch angle can be replaced by the velocity components as measured in an inertial reference frame. The so-called two-system method is derived next. It employes the idea of having two sets of equations of motion derived in different reference frames, and thus, having their singularities at different points. In detailed discussions the problems that appear with both methods are explained, and solutions are presented, the emphasis always being on the use of these equations with optimization methods. Section III also includes a method that allows integration of third-class trajectories as long as they can be flown in the vertical plane. This method results directly from the commonly-used equations of motion after removing a restriction on the flight path angle. Because all methods of Section III have still the bank angle as the control, they are referred to here as Euler-angle methods. Section IV presents the quaternion method. Although this method has been investigated first, it is presented last because it yields the best overall solution and because many details and improvements were not found until the other methods were analyzed. Understanding the Euler-angle methods will also help in understanding the properties of the quaternion method. Because the available literature on quaternions is either complex or erroneous, the quaternion is covered in much detail. The concept of the quaternion is explained, and the rules of quaternion algebra are stated in the first two sections. Next, some necessary relationships are developed. It will then be rather straightforward to derive the actual equations of motion. How to use the quaternion method for parameter optimization methods is emphasized in the following sections

description: In recent years the development of the applications in the field of telecommunications, data processing, control, renewable energy generation, consumer and automotive electronics determined the need for increasingly complex systems, also in shorter time to meet the growing market demand. The increasing complexity is mainly due to the mixed nature of these systems that must be developed to accommodate the new functionalities and to satisfy the more stringent performance requirements of the emerging applications. This means a more complex design and verification process. The key to managing the increased design complexity is a structured and integrated design methodology which allows the sharing of different circuit implementations that can be at transistor level and/or at a higher level (i.e.HDL languages).In order to expedite the mixed systems design process it is necessary to provide: an integrated design methodology; a suitable supporting tool able to manage the entire design process and design complexity and its successive verification.It is essential that the different system blocks (power, analog, digital), described at different level of abstraction, can be co-simulated in the same design context. This capability is referred to as mixed-level simulation.One of the objectives of this research is to design a mixed system application referred to the control of a coupled step-up dc-dc converter. This latter consists of a power stage designed at transistor-level, also including accurate power device models, and the analog controller implemented using VerilogA modules. Digital controllers are becoming very attractive in dc-dc converters for their programmability, ability to implement sophisticated control schemes, and ease of integration with other digital systems. Thus, in this dissertation it will be presented a detailed design of a Flash Analog-to-Digital Converter (ADC). The designed ADC provides medium-high resolution associated to high-speed performance. This makes it useful not only for the control application aforementioned but also for applications with huge requirements in terms of speed and signal bandwidth. The entire design flow of the overall system has been conducted in the Cadence Design Environment that also provides the ability to mixed-level simulations. Furthermore, the technology process used for the ADC design is the IHP BiCMOS 0.25 µm by using 50 GHz NPN HBT devices.

description: From a total data sample of 701.1 pb^-1 recorded with e+e- centre-of-mass energies of sqrt = 161-209 GeV with the OPAL detector at LEP, 11693 W-pair candidate events are selected. These data are used to obtain measurements of the W-pair production cross sections at 10 different centre-of-mass energies. The ratio of the measured cross sections to the Standard Model expectation is found to be: data/SM = 1.002 +- 0.011(stat.) +- 0.007(syst.) +- 0.005(theory), where the uncertainties are statistical, experimental systematics and theory systematics respectively. The data are used to determine the W boson branching fractions, which are found to be consistent with lepton universality of the charged current interaction. Assuming lepton universality, the branching ratio to hadrons is determined to be 67.41 +- 0.37(stat.) +- 0.23(syst.)%, from which the CKM matrix element Vcs is determined to be 0.96+-0.017(stat.)+-0.012(syst.). The differential cross section as a function of the W^- production angle is measured for the qqev and qqmv final states. The results described in this paper are consistent with the expectations from the Standard Model.

description: Various forms of exact laws governing magnetohydrodynamic (MHD) turbulence have been derived either in the incompressibility limit, or for isothermal compressible flows. Here we propose a more general method that allows us to obtain such laws for any turbulent isentropic flow (i.e., constant entropy). We demonstrate that the known MHD exact laws (incompressible and isothermal) and the new (polytropic) one can be obtained as specific cases of the general law when the corresponding closure equation is stated. We also recover all known exact laws of hydrodynamic (HD) turbulence (incompressible, isothermal and polytropic) from this law in the limit ${\bf B}=0$. We furthermore show that the difference between the two forms (isothermal and polytropic) of the MHD exact laws of interest in this work resides in some of the source terms and in the explicit form of the flux term that depends on internal energy. Finally, we apply these two forms to Parker Solar Probe (PSP) data taken in the inner heliosphere to highlight how the different closure equations affect the energy cascade rate estimates.

Prevalenza di Ischemia Inducibile valutata mediante Tomografia Computerizzata a Emissione di Fotone Singolo (SPECT) nei Pazienti con Diabete Mellito di Tipo II e Anomalie Elettrocardiografiche a Riposo: Risultati da uno Studio Prospettico Multicentrico

description: Lo scopo del presente studio è stato di valutare il ruolo aggiuntivo della SPECT cardiaca rispetto ai dati clinici nella definizione della probabilità di ischemia miocardica in pazienti con diabete mellito di tipo II e con anomalie elettrocardiografiche (EGC) a riposo. La popolazione studiata è stata composta di 502 pazienti con una storia di almeno 5 anni di diabete mellito ed anormale ECG a riposo inviati a scintigrafia miocardica da sforzo come parte dello studio Impact of Inducile Ischemia by Stress SPECT (IDIS). Per ogni paziente, un programma computerizzato (CADENZA) è stato utilizzato per determinare la probabilità pre-test di ischemia considerando i dati clinici. I pazienti sono stati classificati in tre sottogruppi: a probabilità di ischemia bassa (<0.15), intermedia (0.15-0.85) ed alta (>0.85). In base al risultato della SPECT, i pazienti sono stati riclassificati.
La morte per causa cardiaca, l’infarto miocardico non fatale e la rivascolarizzazione tardiva sono stati considerati eventi cardiaci. La differenza tra la classificazione corretta ed incorretta in accordo con l’outcome del paziente è stata definita come Net Reclassification Improvement (NRI). Assumendo una indipendenza tra gli individui che hanno avuto e non hanno avuto un evento cardiaco ed adottando il test non parametrico di McNemar per le proporzioni correlate, un semplice test asimptotico è stato impiegato per testare l’ipotesi nulla (H0) per cui NRI=0 (test z).
In base alle variabili cliniche, i pazienti sono stati suddivisi in tre categorie: probabilità di ischemia miocardica bassa (n=123), intermedia (n=365) ed alta (n=19). La SPECT è risultata anormale nel 73% dei pazienti. Dopo l’aggiunta del dato SPECT nel modello, 139 pazienti avevano una probabilità post-test di ischemia bassa, 305 intermedia e 58 alta, con un cambio nella classificazione in 203 (40%) pazienti (test del chi-quadro p<0.0001). Durante il follow-up, completo in 416 (86%) pazienti in un periodo di 41±19 mesi, gli eventi cardiovascolari si sono verificati in 118 (28%) di essi; il NRI è stato di 21% (z=3.15; p<0.005).
In conclusione, i pazienti diabetici con anomalie all’ECG a riposo sono meglio stratificati dalla SPECT piuttosto che dai dati clinici. Un sostanziale numero di pazienti a probabilità pre-test di ischemia bassa o intermedia e che hanno avuto un evento cardiovascolare durante il follow-up, presentano una SPECT anormale.

description: An innovative electromagnetic model for the radar echoes received by a
microwave altimeter is proposed: it is based on fractal models employed both to describe the natural surface and to evaluate the surface scattering behaviour. The scattering surface is modelled by means of the fractional Brownian model (fBm) process, whose realizations are obtained by using the band-limited Weierstrass-Mandelbrot (WM) function. The scattering
process is evaluated by means of the Physical Optics solution specifically derived for fractal surfaces. Rationale to apply this solution to the evaluation (in time domain) of the received echoes is provided. Dependence of the return pulse shapes on surface topography at different roughness scales is highlighted: some relevant meaningful examples are presented. Simulation
results are provided to show the potential of the proposed technique that could be the fundamental element to generate an atlas of expected returns from a given radar altimeter.
