Relativistic two-boson system in presence of electromagnetic plane waves

Publisher: name: arXiv

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The relativistic two-body problem is considered for spinless particles subject to an external macroscopic electromagnetic field. When this field is made of the monochromatic superposition of two counter-propagating plane waves (and provided the mutual interaction between particles is known), it is possible to write down explicitly a pair of coupled wave equations (corresponding to a pair of mass-shell constraints) which takes into account also the field contribution. These equations are manifestly covariant; constants of the motion are exhibited, so one ends up with a reduced problem involving five degrees of freedom.

Magneto- and Baro- Caloric Responses in Magnetovolumic Systems

Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: By means of a mean-field model extended to include magnetovolumic effects we study the effect of external fields on the thermal response characterized either by the isothermal entropy change and/or the adiabatic temperature change. The model includes two different situations induced by the magnetovolumic coupling. (i) A first order para- ferromagnetic phase transition that entails a volume change. (ii) An inversion of the effective exchange interaction that promotes the occurrence of an antiferromagnetic phase at low temperatures. In both cases, we study the magneto- and baro-caloric effects as well as the corresponding cross caloric responses. By comparing the present theoretical results with available experimental data for several materials we conclude that the present thermodynamical model reproduces the general trends associated with the considered caloric and cross caloric responses.

From Constraints to Opportunities: Efficient Object Detection Learning for Humanoid Robots

Publisher: name: Universit� degli studi di Genova
Year: 2020

description: Reliable perception and efficient adaptation to novel conditions are priority skills for robots that function in ever-changing environments. Indeed, autonomously operating in real world scenarios raises the need of identifying different context?s states and act accordingly. Moreover, the requested tasks might not be known a-priori, requiring the system to update on-line. Robotic platforms allow to gather various types of perceptual information due to the multiple sensory modalities they are provided with. Nonetheless, latest results in computer vision motivate a particular interest in visual perception. Specifically, in this thesis, I mainly focused on the object detection task since it can be at the basis of more sophisticated capabilities. The vast advancements in latest computer vision research, brought by deep learning methods, are appealing in a robotic setting. However, their adoption in applied domains is not straightforward since adapting them to new tasks is strongly demanding in terms of annotated data, optimization time and computational resources. These requirements do not generally meet current robotics constraints. Nevertheless, robotic platforms and especially humanoids present opportunities that can be exploited. The sensors they are provided with represent precious sources of additional information. Moreover, their embodiment in the workspace and their motion capabilities allow for a natural interaction with the environment. Motivated by these considerations, in this Ph.D project, I mainly aimed at devising and developing solutions able to integrate the worlds of computer vision and robotics, by focusing on the task of object detection. Specifically, I dedicated a large amount of effort in alleviating state-of-the-art methods requirements in terms of annotated data and training time, preserving their accuracy by exploiting robotics opportunity.

description: Results of a search for new phenomena in events with large missing transverse momentum and a Higgs boson decaying to two photons are reported. Data from proton-proton collisions at a center-of-mass energy of 8 TeV and corresponding to an integrated luminosity of 20.3 fb$^{-1}$ have been collected with the ATLAS detector at the LHC. The observed data are well described by the expected Standard Model backgrounds. Upper limits on the cross section of events with large missing transverse momentum and a Higgs boson candidate are also placed. Exclusion limits are presented for models of physics beyond the Standard Model featuring dark-matter candidates.

description: In this review we discuss the population of stellar-mass black holes in our galaxy and beyond, which are the extreme endpoints of massive star evolution. In particular we focus on how we can attempt to balance the available accretion energy with feedback to the environment via radiation, jets and winds, considering also possible contributions to the energy balance from black hole spin and advection. We review quantitatively the methods which are used to estimate these quantities, regardless of the details of the astrophysics close to the black hole. Once these methods have been outlined, we work through an outburst of a black hole X-ray binary system, estimating the flow of mass and energy through the different accretion rates and states. While we focus on feedback from stellar mass black holes in X-ray binary systems, we also consider the applicability of what we have learned to supermassive black holes in active galactic nuclei. As an important control sample we also review the coupling between accretion and feedback in neutron stars, and show that it is very similar to that observed in black holes, which strongly constrains how much of the astrophysics of feedback can be unique to black holes.

The branching fractions are measured to be $\B(J/ψ\rightarrow ρπ) = \big(2.072\pm 0.017 \pm 0.062 \big)\cdot 10^{-2}$ and $\B(J/ψ\rightarrow π^+π^-π^0) = \big(1.878 \pm 0.013 \pm 0.051 \big)\cdot 10^{-2}$, where the first uncertainties are statistical and the second systematic. Our results are more precise than the previous relative measurements.

description: We apply the recently developed adaptive non-harmonic model based on the wave-shape function, as well as the time-frequency analysis tool called synchrosqueezing transform (SST) to model and analyze oscillatory physiological signals. To demonstrate how the model and algorithm work, we apply them to study the pulse wave signal. By extracting features called the spectral pulse signature, {and} based on functional regression, we characterize the hemodynamics from the radial pulse wave signals recorded by the sphygmomanometer. Analysis results suggest the potential of the proposed signal processing approach to extract health-related hemodynamics features.

description: Questo elaborato mira a comprendere l?impatto delle politiche securitarie in ambito migratorio sulla realt� concreta del sistema di accoglienza italiano, con un focus particolare sulle dinamiche illegali e criminali che esse contribuiscono a generare. La ricerca si inserisce all?interno di un momento storico molto particolare, che vede le politiche di accoglienza oggetto di cambiamenti su larga scala. Il caso studio analizzato riguarda il Cara di Mineo, il pi� grande centro di accoglienza nazionale, chiuso definitivamente nel luglio 2019. In questa struttura si ripropongono, amplificati, i meccanismi e i cortocircuiti propri dell?intero sistema. In particolare, l?indagine verte sul labile confine tra pratiche legali e illegali, sviluppatesi in un contesto segnato da marginalizzazione e isolamento. A queste dinamiche afferiscono comportamenti criminali specifici, come lo sviluppo di una cellula di criminalit� organizzata nigeriana, che vengono esaminati sempre rispetto alla relazione con il terreno in cui si diffondono. Quella che si configura come una sorta di ?fabbrica dell?irregolarit�?, secondo i risultati della ricerca sul campo, svolge un ruolo cruciale nella sovrapposizione dei concetti di vittimizzazione e di agency criminale.

description: Free-electron radiation is a fundamental photon emission process that is induced by fast-moving electrons interacting with optical media. Historically, it has been understood that, just like any other photon emission process, free-electron radiation must be constrained within a finite time interval known as the "formation time", whose concept is applicable to both Cherenkov radiation and transition radiation, the two basic mechanisms describing radiation from a bulk medium and from an interface, respectively. Here we reveal an alternative mechanism of free-electron radiation far beyond the previously defined formation time. It occurs when a fast electron crosses the interface between vacuum and a plasmonic medium supporting bulk plasmons. While emitted continuously from the crossing point on the interface - thus consistent with the features of transition radiation - the extra radiation beyond the conventional formation time is supported by a long tail of bulk plasmons following the electron's trajectory deep into the plasmonic medium. Such a plasmonic tail mixes surface and bulk effects, and provides a sustained channel for electron-interface interaction. These results also settle the historical debate in Ferrell radiation, regarding whether it is a surface or bulk effect, from transition radiation or plasmonic oscillation.

description: Falsificare significa attribuire a un manufatto un?identit� che non gli appartiene con lo scopo di ottenere un beneficio a proprio vantaggio o a danno di altri soggetti. Nel corso dei secoli la falsificazione ha interessato reperti paletnologici, sculture d?arte contemporanea, ritrovamenti archeologici, documenti, arredi, dipinti, reliquie e altro ancora. Gli strumenti musicali certamente non sono stati risparmiati dal fenomeno, che, anzi, si � dimostrato una vera e propria costante nella storia di questi prodotti. Dai casi pi� antichi conosciuti risalenti alla met� del Cinquecento, fino a quelli pi� recenti al principio del nuovo millennio, non si sono registrate pause nella realizzazione di esemplari fasulli e la presenza di contraffazioni, plagi o alterazioni ha interessato pressoch� tutti i continenti. La falsificazione ha potuto prosperare perch� ha sempre svolto la funzione essenziale di facilitare la reperibilit� di opere molto ricercate ma, per motivi economici o per scarsit� di modelli esistenti, difficilmente raggiungibili. In particolare � stata in grado di sfruttare la domanda diffusa di strumenti dalle elevate qualit� tecnico-sonore, di reperti antichi provenienti dalle passate civilt� musicali e di beni in cui investire ingenti capitali, concentrando gli interventi sui parametri fondamentali di uno strumento, ossia la sua et�, il suo luogo d?origine e l?identit� del suo autore. Dalla comparsa quarant?anni fa del primo studio sistematico sulla figura di Leopoldo Franciolini, l?organologia ha associato la creazione di falsi strumenti musicali a questo antiquario fiorentino in maniera tanto automatica quanto eccessiva. Molti infatti sono stati i responsabili delle pratiche fraudolente in questo settore oltre a Franciolini, attivi prima di lui, dopo di lui e contemporaneamente a lui. Alcuni nomi possono essere citati, come Isaac Ehe, i fratelli Voller, Herny Werro, o Yuko Kanda, ma la verit� � che la maggior parte dei falsari � rimasta nell?anonimato. Infine, se da un lato la falsificazione di strumenti musicali ha conosciuto storicamente un?indubbia espansione, dall?altro per� l?interpretazione della natura di falso non pu� n� deve essere forzata. L?inautenticit� di uno strumento, difatti, non � garanzia di falsit� senza che sia accompagnata dal riconoscimento dell?intento programmatico d?ingannare. Cos� come la mancata paternit� individuale riscontrata per uno strumento non rappresenta un criterio valido per ravvisarne e stabilirne la sofisticazione.

description: A substantial proportion of patients with gastro-oesophageal reflux disease (GERD) have only a partial response to proton pump inhibitor (PPI) therapy. Prokinetic drugs may improve reflux symptoms by enhancing oesophageal motility and gastric emptying. To evaluate the effect of revexepride, a novel prokinetic 5-hydroxytryptamine type 4 (5-HT4 ) receptor agonist, compared with placebo, in patients with GERD who have a partial response to PPIs. A phase 2b, double-blind, parallel-group study was conducted, in which patients were randomised to one of three revexepride treatment groups (0.1, 0.5 and 2.0 mg three times daily) or placebo (1:1:1:1 ratio). Daily e-diary data captured patients' symptoms over an 8-week treatment period. The primary efficacy outcome was the weekly percentage of regurgitation-free days in the second half of the study (weeks 5-8). In total, 480 patients were randomised and 477 received treatment (mean age 47.9 years; 61% women). The mean percentage of regurgitation-free days increased from baseline (range, 15.0-18.8%) to week 8 (62.3-70.5%) in all four study arms; however, there were no statistically significant differences in this change between placebo and the three treatment arms. No dose-dependent relationship in treatment effect was observed for any of the study endpoints. The incidence of treatment-emergent adverse events (TEAEs) was revexepride dose-dependent. Only one serious TEAE occurred and none resulted in death. Revexepride was no more effective than placebo in controlling regurgitation in patients with GERD symptoms partially responsive to PPIs. Revexepride was well tolerated. ClinicalTrials.gov Identifier: NCT01472939.
title: Development of MAST-U Langmuir Probe Interpretation Through Particle-in-cell Simulation and Experiment

description: Interpreting flush-mounted Langmuir probes at small angles of magnetic field incidence –routinely found in tokamak plasma facing components (PFCs) by design – is notoriously problematic due to the difficulty of accounting properly for sheath expansion. The Mega Amp Spherical Tokamak Upgrade (MAST-U) has 850 probes installed with a novel probe tip designed to mitigate the effects of sheath expansion. This angled-tip design has been investigated through experimental and computational means, to both verify that the design works as intended and to provide insight on how best to interpret the IV characteristics in preparation for the upcoming MAST-U physics campaign.A rederivation of Bergmann and Murphy-Sugrue’s sheath expansion model, and associated parameter, is presented for the novel geometry of the MAST-U angled-tip probe.Two alternate formulations are presented with different approximations of the sheath shape around the probe. This model was verified with 2D3V particle-in-cell simulations, using the code SPICE, of the plasma around a flush-mounted probe tip and an angled-tip probe with MAST-U-like physical proportions. The rotated-rectangular model was found to describe the sheath expansion well for both probes, with new values found for the sheath expansion parameter coefficients for the angled-tip case. An investigation of the effect of wall potential on probe measurements is also presented. Additional current was collected for Vw < Vfl due to the reduced wall-sheath height, which must be accounted for to ensure accurate density measurements with probes in this scenario. A method to correct for this additional current is presented. A 4-probe array of MAST-U-like angled-tip probes was also taken to the linear plasma device Magnum-PSI at the Dutch Institute for Fundamental Energy Research (DIFFER). Parameter scans were made on a range of plasmas in conditions comparable to those expected in MAST-U. Plasma parameters were extracted from the measured IV characteristics – using a novel fitting approach that minimised a goodness-of-fit parameter (TeδTe) – and compared to Magnum-PSI Thomson scattering measurements. The measured plasma parameters show that the MAST-U angled-tip design seems to successfully mitigate the effects of sheath expansion at low angles of magnetic field incidence. The standard MAST-U Langmuir probe also shows an apparent upper operational limit of θ= 8°. This covers the vast majority of expected plasma configurations in MAST-U when running both conventional and Super-X configurations.

description: BACKGROUND: Seasonal variation has been reported in diagnosis of eosinophilic oesophagitis (EoE), but results are not consistent across studies and there are no national-level data in the USA.

AIM: To determine if there is seasonal variation in diagnosis of oesophageal eosinophilia and EoE in the USA, while accounting for factors such as climate zone and geographic variation.

METHODS: This was a cross-sectional study using a USA national pathology database. Patients with oesophageal eosinophilia (≥15 eosinophils per high-power field) comprised the primary case definition and were compared to those with normal oesophageal biopsies. We calculated the crude and adjusted odds of oesophageal eosinophilia by season, as well as by day of the year. Sensitivity analyses were performed using more restrictive case definitions of EoE, and after stratification by climate zone.

RESULTS: Exactly, 14 524 cases with oesophageal eosinophilia and 90 459 normal controls were analysed. The adjusted odds of oesophageal eosinophilia were higher in the late spring and summer months, with the highest odds in July (aOR: 1.13; 95% CI: 1.03-1.24). These findings persisted with increasing levels of oesophageal eosinophilia, as well as across EoE case definitions. Seasonal variation was strongest in temperate and cold climates, and peak diagnosis varied by climate zone.

CONCLUSIONS: There is a mild but consistent seasonal variation in the diagnosis of oesophageal eosinophilia and EoE, with cases more frequently diagnosed during summer months. These findings take into account climate and geographic differences, suggesting that aeroallergens may contribute to disease development or flare.

description: We consider small perturbations of expanding maps induced by skew-product mappings whose base dynamics are not invertible necessarily. Adopting a previously developed perturbative spectral approach, we show stability of the densities of the unique absolutely continuous invariant probability measures for expanding maps under these perturbations, and upper bounds on the rate of exponential decay of fiber correlations associated to the measures as the noise level goes to zero.

MIDICHLORIA MITOCHONDRII AS AN EMERGING INFECTIOUS AGENT: MOLECULAR AND IMMUNOLOGICAL STUDIES ON THE INTRA-MITOCHONDRIAL SYMBIONT OF THE HARD TICK IXODES RICINUS
Creators: name: MARICONTI, MARA

description: M. mitochondrii is an alpha proteobacteria belonging to the order Rickettsiales. It is an intracellular bacterium present in different tick species and in particular it is studied in the hard tick I. ricinus. The prevalence of M. mitochondrii in I. ricinus is 100% in females and around 40% in males. The recently sequenced genome of M. mitochondrii revealed the presence of 26 putative flagellar genes. Open questions are whether these genes are expressed and whether they possess the domains expected for the flagellar function. To answer to these questions, a putative flagellar protein has been produced in recombinant form, purified and used for the production of polyclonal antibodies. These were used for immunostainig and immunogold detection of M. mitochondrii in I. ricinus ovary. Furthermore, the expression of seven flagellar genes has been evaluated and the proteins codified by the 26 genes have been analyzed for the presence of domains specific for flagellar proteins. In I. ricinus, M. mitochondrii is observed in the oocytes and in other cells of the ovary, where the symbiont is present in the cell cytoplasm and inside the mitochondria. No studies have so far investigated whether M. mitochondrii is present in the salivary glands of the tick and whether it is transmitted to vertebrates during the tick blood meal. To address the above questions, we used a recombinant antigen of M. mitochondrii (to screen vertebrate sera) and antibodies against this antigen (for the staining of the symbiont in the salivary glands). In conclusion, the obtained results provide evidences that: 1) M. mitochondrii is the first rickettsiales that posses a flagellar structure; 2) M. mitochondrii, detected in the salivary glands of I. ricinus, could be transmitted to the vertebrate host during the tick bite; 3) vertebrate hosts develop an antigenic response against a recombinant protein of M. mitochondrii suggesting the possibility that M. mitochondrii is infectious to vertebrates.
title: Social Support in Palliative Care: A Realist Exploration of Hospice Day Services

description: Hospices offer psychosocial support for people with incurable illness, and those approaching death or bereavement. This project uses mixed methods and realist evaluation principles to extend understanding of social support in palliative care. It aims to describe practice and function of social support in hospice day services, to develop appropriate methods for future effectiveness and cost-effectiveness research. A systematic review summarises available quantitative evidence on effectiveness of palliative care interventions that facilitate social support. There is some evidence of short-term benefits to patients in psychological and physical domains, however consistent difficulties in method are reported, and social support is underexplored as an outcome of intervention. An online survey of hospice day service managers in the UK & ROI establishes an overview of services that facilitate social support for people living in the community with life-limiting illness. These are: multi-component interventions, activity groups, formal support groups, befriending, and informal social activities. The survey documents a diverse and evolving sector that is active in facilitating social support. A longitudinal cohort study observed patient outcomes using validated measures of perceived social support, loneliness, depression, and health-related quality of life. Participants (n=30) are recruited across four locations, but attrition is high. The outcome measures appeared acceptable to patients, and sensitive to change. Improvement is observed in emotional support (a subscale) and in loneliness (n=19). Qualitative investigation included nineteen interviews with hospice service-providers. Analysis using realist principles provides explanation of how patient and hospice context might interact to produce beneficial mechanisms that lead to outcomes beyond the hospice. Reciprocity and honesty within the group could be enabled through autonomy and familiarity. These processes could reduce distress and improve acceptance of change and mortality. This thesis proposes an initial programme theory that can be extended or developed. It suggests how, in some contexts, social opportunities lead to changes in emotions and behaviour, that might ultimately increase personal and practical resources to cope with illness and death. Hospices might seek to foster beneficial social support, and collective opportunities to acknowledge mortality.
