description: With the recent developments in the field of Natural Language Processing, there has been a rise in the use of different architectures for Neural Machine Translation. Transformer architectures are used to achieve state-of-the-art accuracy, but they are very computationally expensive to train. Everyone cannot have such setups consisting of high-end GPUs and other resources. We train our models on low computational resources and investigate the results. As expected, transformers outperformed other architectures, but there were some surprising results. Transformers consisting of more encoders and decoders took more time to train but had fewer BLEU scores. LSTM performed well in the experiment and took comparatively less time to train than transformers, making it suitable to use in situations having time constraints.

description: The objective of the Ph.D. thesis is to put the basis of an all-embracing link analysis procedure that may form a general reference scheme for the future state-of-the-art of RF/microwave link design: it is basically meant as a circuit-level simulation of an entire radio link, with – generally multiple – transmitting and receiving antennas examined by EM analysis. In this way the influence of mutual couplings on the frequency-dependent near-field and far-field performance of each element is fully accounted for. The set of transmitters is treated as a unique nonlinear system loaded by the multiport antenna, and is analyzed by nonlinear circuit techniques. In order to establish the connection between transmitters and receivers, the far-fields incident onto the receivers are evaluated by EM analysis and are combined by extending an available Ray Tracing technique to the link study. EM theory is used to describe the receiving array as a linear active multiport network. Link performances in terms of bit error rate (BER) are eventually verified a posteriori by a fast system-level algorithm.
In order to validate the proposed approach, four heterogeneous application contexts are provided. A complete MIMO link design in a realistic propagation scenario is meant to constitute the reference case study. The second one regards the design, optimization and testing of various typologies of rectennas for power generation by common RF sources. Finally, the project and implementation of two typologies of radio identification tags, at X-band and V-band respectively. In all the cases the importance of an exhaustive nonlinear/electromagnetic co-simulation and co-design is demonstrated to be essential for any accurate system performance prediction.

description: A simple salicylaldehyde-based Schiff base 2,2'-((1,3-phenylenebis(azanylylidine))bis(methanylylidene))dipehnol (PAMD) was synthesised by condensation reaction between salicylaldehyde and benzene-1,3-diamine (2:1 ratio) and characterised by spectral techniques such as NMR, FTIR and HRMS, followed by investigation for its spectroscopic behaviour towards diverse metal ions using UV and fluorescence studies. PAMD was found to exhibit sensitivity towards Cu2+ only. The receptor PAMD was then explored for its electrochemical behaviour using cyclic voltammetry, which displayed an irreversible anodic peak at 1.00 V due to imine group. Furthermore, PAMD was subjected to differential pulse voltammetry, which exhibited a sensitive response for Cu2+ in the linear range of 0–3.8 μM with lowest detection limit of 0.03 μM. The complexation between PAMD and Cu2+ was also supported by large values of binding constant (1.3 × 105 M−1) and negative free energy change (ΔG∘ = -29.2 kJmol−1) obtained from Benesi–Hildebrand equation. The carbon paste electrode (CPE) modified with PAMD displayed a Nernstian response to Cu2+ in the concentration range from 1.0 × 10−6 to 1.0 × 10−1 M and lowest detection limit of 4.0 × 10−7 M. The PAMD-CPE was successfully applied for determination of Cu2+ content in real samples such as groundwater, soil, and food grains (wheat and rice).

Oxylipins biosynthesis in Lactobacillus helveticus in the presence of oxidative stress

Subjects: AGR/16 Microbiologia agraria

description: This PhD thesis is aimed at studying the possible pathways and the mechanisms that can trigger oxylipins biosynthesis, and particularly that of short chain aldehydes and alcohols, in Lactobacillus helveticus, also in the presence of oxidative stress, using a totally labelled linoleic acid as precursor. In plants and fungi these molecules, involved in defence mechanisms against pathogens and in communication systems, derive from the oxidation of cellular unsaturated fatty acids (UFAs) and their accumulation is associated with stress exposure. Since some oxylipins are produced also by lactobacilli, it is possible to hypothesize that a metabolic pathway from UFAs to oxylipins, similar to what happens in plants and fungi, is present also in lactic acid bacteria. The results obtained pointed out that some volatile molecules are the result of UFAs catabolism, since they appear only when cells are incubated in their presence. Labelled linoleic acid is integrated in the membrane and subsequently transformed into aldehydes and alcohols, whose extent and carbon atoms number depend on stress exposure. The enzymes responsible for this metabolic pathway in plants and fungi (e.g. lipoxygenase, dioxygenase) seem to be absent in Lactobacillus helveticus and in other lactobacilli. Proteomic analyses show the over expression of many proteins, including thioredoxin reductase (part of the bacterial oxidative defence system), mainly in cells grown with linoleic acid without oxidative stress exposure, confirming that linoleic acid itself induces oxidative stress. 6 general oxidoreductases (class including dioxygenases and peroxidase) were found and therefore a deeper investigation on them could be productive in elucidating all steps involved in oxylipins biosynthesis in bacteria. Due to the multiple role of oxylipins (flavouring agents, antimicrobial compounds and interspecific signalling molecules) the identification of genes involved and regulating factors should have an important biotechnological impact, also allowing the overproduction of selected bioactive molecules.

description: Timing of waiting list entrance for patients with cystic fibrosis in need of pulmonary transplant: the experience of a regional referral centre 

Objective: Evaluation of parameters that can predict a rapid decay of general conditions of patients affected by Cystic Fibrosis (CF) with no specific criteria to be candidate to pulmonary transplant.

Material and methods: Fifteen patients with CF who died for complications and 8 who underwent lung transplantation in the 2000-2010 decade, were enrolled. Clinical data 2 years before the event (body max index, FEV1%, number of EV antibiotic treatments per year, colonization with Methicillin-resistant Staphylococcus aureus (MRSA), pseudomonas aeruginosa mucosus, burkholderia cepacia, pulmonary allergic aspergilosis) were compared among the 2 groups.

Results: Mean FEV1% was significantly higher and mean number of antibiotic treatment was lower in deceased than in the transplanted patients (p<0.002 and p<0.001 respectively). Although in patients who died there were no including criteria to enter the transplant list 2 years before the exitus, suggestive findings such as low BMI (17.3), high incidence of hepatic pathology (33.3%), diabetes (50%), and infections with MRSA infection (25%), Pseudomonas aeruginosa (83.3%) and burkholderia cepacia (8.3%) were found with no statistical difference with transplanted patients, suggesting those patients were at risk of severe prognosis. In patients who died, females were double than males.

Conclusion: While evaluating patients with CF, negative prognostic factors such as the ones investigated in this study, should be considered to select individuals with high mortality risk who need stricter therapeutical approach and follow up. Inclusion of those patients in the transplant waiting list should be taken into account.
Dependence of inner accretion disk stress on parameters: the Schwarzschild case

description: We explore the parameter dependence of inner disk stress in black hole accretion by contrasting the results of a number of simulations, all employing 3-d general relativistic MHD in a Schwarzschild spacetime. Five of these simulations were performed with the intrinsically conservative code HARM3D, which allows careful regulation of the disk aspect ratio, H/R; our simulations span a range in H/R from 0.06 to 0.17. We contrast these simulations with two previously reported simulations in a Schwarzschild spacetime in order to investigate possible dependence of the inner disk stress on magnetic topology. In all cases, much care was devoted to technical issues: ensuring adequate resolution and azimuthal extent, and averaging only over those time-periods when the accretion flow is in approximate inflow equilibrium. We find that the time-averaged radial-dependence of fluid-frame electromagnetic stress is almost completely independent of both disk thickness and poloidal magnetic topology. It rises smoothly inward at all radii (exhibiting no feature associated with the ISCO) until just outside the event horizon, where the stress plummets to zero. Reynolds stress can also be significant near the ISCO and in the plunging region; the magnitude of this stress, however, depends on both disk thickness and magnetic topology. The two stresses combine to make the net angular momentum accreted per unit rest-mass 7-15% less than the angular momentum of the ISCO.

description: We show that real model sets with real internal spaces are determined, up to translation and changes of density zero by their two- and three-point correlations. We also show that there exist pairs of real (even one dimensional) aperiodic model sets with internal spaces that are products of real spaces and finite cyclic groups whose two- and three-point correlations are identical but which are not related by either translation or inversion of their windows. All these examples are pure point diffractive. Placed in the context of ergodic uniformly discrete point processes, the result is that real point processes of model sets based on real internal windows are determined by their second and third moments.

description: This paper presents the design, simulation, and analytical modeling of the single proposed axis MEMSbased capacitive accelerometer. Analytical modeling has been done for frequency and displacement sensitivity. The performance of the accelerometer was tested for both static and dynamic conditions, and the corresponding static capacitance value was calculated and was found to be C0=0.730455pF, a response time of 95.17μs, and settling time of 7.261ms and the displacement sensitivity Sd= 3.5362* m/g. It was observed that the sensitivity of the accelerometer depends on its design parameters like beam length, overlap area of comb, sensing mass, and the number of interdigital fingers. A novel capacitive accelerometer has been designed for an operating frequency of 2.1kHz The accelerometer was designed using COMSOL Multiphysics and analyzed using the MATLAB simulator tool. The single proposed axis MEMS-based capacitive accelerometer is suitable for automobile applications such as airbag deployment and navigation.

Gauge Mediation with a small mu term and light squarks

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We consider a solution to the mu problem in the context of Non-Minimal Gauge Mediation with two Singlets and Low-Scale Messengers. This solution reduces tuning associated with the "Little Hierarchy" problem by permitting a naturally small mu term (100-300 GeV) due to small mixing between the Singlets. The smallness of mu also relies crucially on compressing the Gauge Mediated sparticle spectrum resulting in 330-400 GeV squarks. In addition to a small mu term, the theory achieves a Higgs mass > 114.4 GeV through a large Higgs quartic coupling when tanbeta ~ 1.5. The vacua studied are globally stable with all couplings perturbative to the GUT scale. The amount of tuning required to get the correct Electroweak scale is of order 10%, with a similar residual tuning associated with the region of parameter space where the lightest CP-even Higgs mass is above the LEP bound.

description: Emission in the ultraviolet continuum is a salient signature of the hot, massive and consequently short-lived, stellar population that traces recent or ongoing star formation. With the aim of mapping star forming regions and morphologically separating the generic star formation from that associated with the galaxy-scale jet activity, we obtained high-resolution HST/UV imaging for a sample of nine compact radio sources. Out of these, seven are known Compact Steep Spectrum (CSS) galaxies that host young, kpc-scale radio sources and hence are the best candidates for studying radio-mode feedback on galaxy scales, while the other two form a control sample of larger sources. Extended UV emission regions are observed in six of the seven CSS sources showing close spatial alignment with the radio-jet orientation. If other mechanisms possibly contributing to the observed UV emission are ruled out, this could be evidence in support of jet-triggered star formation in the CSS phase of radio galaxy evolution.

description: While there has been an ever-increasing drive to digitally transform educational institutions over the past decade, concerns related to the environmental and human impact of digital technology consumption appear absent from policy in this area. Such concerns about resource depletion, environmental degradation, and human exploitation are likely to be downplayed and met with resistance from advocates of the digital transformation agenda. For schools to seriously consider the damaging effects of the ever increasing digital technology consumption, effective leadership is needed. Traditionally the idea of digital leadership in schools was seen as a specified role often undertaken and attributed to singular change agents or individuals. This paper argues that more democratic and inclusive leadership is needed to enable teachers to take ownership of this change agenda, thereby enabling schools to proactively respond to this sustainability crisis in an ethical and empathetic manner. This alone is not sufficient, however, as a shift from the dominant techno-positive mindset is also needed to allow teachers to critically reflect on this digital transformation agenda. The paper argues that if such conditions are established, more ethically driven responses to digital technology practices are likely to emerge.
The development and use of social accounts as a means of evaluating the effectiveness of community services : a case study of the Vancouver Police Department
Creators: name: Jessup, John Alan
Publisher: name: University of British Columbia
Year: 2010

description: The scope for physical planning and development in many older, more established cities in North America is rapidly declining. In these cities, the role of the planner is shifting to meet a new challenge, the improvement of the quality of life. One of the principal methods of improving the quality of life in cities has been the provision of community services. This is resulting in a new role for the planner, that of monitoring and evaluating the efficiency and effectiveness of community services. The police service was taken as a vehicle for developing a method of evaluation for any community service in any city. The thesis identifies major police functions and assigns them to the police programs they are capable of supporting. A set of performance accounts is developed for each program consisting of input, output and impact accounts. The Input Account describes the resources allocated to each police program. The Output Account describes the productivity of these resources in carrying out the police functions. And, the Impact Account describes the effectiveness of these functions in bringing about the desired improvement in the quality of life. Moreover, the quantitative and qualitative indicators of input, output and impact contained in the accounts are related to five central questions of program evaluation. Furthermore, the indicators of input, output and impact contained in the accounts are the data from which a mathematical model of the police organization, the community and the interrelationship between them can be constructed. This model will have the predictive power of anticipating the outcome of proposed allocative decisions in advance of their actual implementation. Thus, the thesis develops a method not only for evaluating the past performance of previous allocative decisions but the anticipated performance of proposed allocative decisions as well.

description: In this article, we study the finite temperature Casimir effect for scalar field with Robin boundary conditions on two parallel plates in a background spacetime that has a compact internal manifold with arbitrary geometry. The finite temperature Casimir force acting on the plates is derived using the piston approach, with which we show that the divergences of the Casimir forces from the region between the plates and the region outside the plates cancel each other. The nature and asymptotic behaviors of the Casimir force at different limits such as small and large plate separation, low and high temperature, are studied in detail. The range of Robin coefficients where the Casimir force are always attractive or always repulsive are determined. There are also some range of the Robin coefficients where the Casimir force is shown to be attractive at small plate separation and repulsive at large plate separation, or vise versa.

description: We propose a scheme to assign a 4-momentum to each WIMP in new physics event producing a pair of mother particles each of which decays to an invisible weakly interacting massive particle (WIMP) plus some visible particle(s). The transverse components are given by the value that determines the event variable M_T2, while the longitudinal component is determined by the on-shell condition on the mother particle. Although it does not give the true WIMP momentum in general, this M_T2-assisted on-shell reconstruction of missing momenta provides kinematic variables well correlated to the true WIMP momentum, and thus can be useful for an experimental determination of new particle properties. We apply this scheme to some processes to measure the mother particle spin, and find that spin determination is possible even without a good knowledge of the new particle masses.

description: 6D object pose tracking has been extensively studied in the robotics and computer vision communities. The most promising solutions, leveraging on deep neural networks and/or filtering and optimization, exhibit notable performance on standard benchmarks. However, to our best knowledge, these have not been tested thoroughly against fast object motions. Tracking performance in this scenario degrades significantly, especially for methods that do not achieve real-time performance and introduce non negligible delays. In this work, we introduce ROFT, a Kalman filtering approach for 6D object pose and velocity tracking from a stream of RGB-D images. By leveraging real-time optical flow, ROFT synchronizes delayed outputs of low frame rate Convolutional Neural Networks for instance segmentation and 6D object pose estimation with the RGB-D input stream to achieve fast and precise 6D object pose and velocity tracking. We test our method on a newly introduced photorealistic dataset, Fast-YCB, which comprises fast moving objects from the YCB model set, and on the dataset for object and hand pose estimation HO-3D. Results demonstrate that our approach outperforms state-of-the-art methods for 6D object pose tracking, while also providing 6D object velocity tracking. A video showing the experiments is provided as supplementary material.

description: We consider the spectrum of the Fibonacci Hamiltonian for small values of the coupling constant. It is known that this set is a Cantor set of zero Lebesgue measure. Here we study the limit, as the value of the coupling constant approaches zero, of its thickness and its Hausdorff dimension. We announce the following results and explain some key ideas that go into their proofs. The thickness tends to infinity and, consequently, the Hausdorff dimension of the spectrum tends to one. Moreover, the length of every gap tends to zero linearly. Finally, for sufficiently small coupling, the sum of the spectrum with itself is an interval. This last result provides a rigorous explanation of a phenomenon for the Fibonacci square lattice discovered numerically by Even-Dar Mandel and Lifshitz.

description: Inflationary dynamics driven by multiple fields, especially with nonminimal couplings, allow for highly interesting features such as isocurvature, non-Gaussianity, and preheating. In this paper, we study two-field inflation in the context of purely affine gravity, where the metrical structure results from the dynamics of the spacetime affine connection. We introduce a covariant formulation in the new framework and show that it leads to a curved field space which can produce conspicuous departure from the purely metric gravity. In the case where the fields are canonical, the field manifold gains a conformally flat shape. Interestingly, while the manifold is generally curved, it is possible to be flattened by allowing specific non-canonical field kinetic terms. This in turn simplifies the inflationary dynamics significantly while allowing for new predictions due to the effects of the nonminimal coupling function on the potential solely. We use this new feature in studying two-field inflation driven by quartic potentials for given parameter constants. We perform a numerical solution of the slow-roll dynamics and track the possible non-Gaussianity. We focus on field parameters that allow for spectral indices within the favored region of the Planck results. These are associated to tiny tensor-to-scalar ratios, $r \sim 10^{-6}$ for single field and $r \sim 10^{-4}$ for two-fields. We also show that two-field Higgs inflation may favor a curved field manifold.

description: The main problem connected to cone beam computed tomography (CT) systems for
industrial applications employing 450 kV X-ray tubes is the high amount of scattered
radiation which is added to the primary radiation (signal). This stray radiation leads to
a significant degradation of the image quality. A better understanding of the scattering
and methods to reduce its effects are therefore necessary to improve the image quality.
Several studies have been carried out in the medical field at lower energies, whereas
studies in industrial CT, especially for energies up to 450 kV, are lacking. Moreover,
the studies reported in literature do not consider the scattered radiation generated by
the CT system structure and the walls of the X-ray room (environmental scatter). In
order to investigate the scattering on CT projections a GEANT4-based Monte Carlo
(MC) model was developed. The model, which has been validated against
experimental data, has enabled the calculation of the scattering including the
environmental scatter, the optimization of an anti-scatter grid suitable for the CT
system, and the optimization of the hardware components of the CT system. The
investigation of multiple scattering in the CT projections showed that its contribution
is 2.3 times the one of primary radiation for certain objects. The results of the
environmental scatter showed that it is the major component of the scattering for
aluminum box objects of front size 70 x 70 mm2 and that it strongly depends on the
thickness of the object and therefore on the projection. For that reason, its correction is
one of the key factors for achieving high quality images. The anti-scatter grid
optimized by means of the developed MC model was found to reduce the scatter-toprimary
ratio in the reconstructed images by 20 %. The object and environmental
scatter calculated by means of the simulation were used to improve the scatter
correction algorithm which could be patented by Empa. The results showed that the
cupping effect in the corrected image is strongly reduced. The developed CT
simulation is a powerful tool to optimize the design of the CT system and to evaluate
the contribution of the scattered radiation to the image. Besides, it has offered a basis
for a new scatter correction approach by which it has been possible to achieve images with the same spatial resolution as state-of-the-art well collimated fan-beam CT with a
gain in the reconstruction time of a factor 10. This result has a high economic impact
in non-destructive testing and evaluation, and reverse engineering.

Apparently noninvariant terms of $U(N)\times U(N)$ nonlinear sigma model in the one-loop approximation

description: We show how the Apparently Noninvariant Terms (ANTs), which emerge in perturbation theory of nonlinear sigma models, are consistent with the nonlinearly realized symmetry by employing the Ward-Takahashi identity (in the form of an inhomogeneous Zinn-Justin equation). In the literature the discussions on ANTs are confined to the SU(2) case. We generalize them to the U(N) case and demonstrate explicitly at the one-loop level that despite the presence of divergent ANTs in the effective action of the "pions", the symmetry is preserved.

description: In this paper, we recall the definition of twisted K-theory in various settings. We prove that for a twist $τ$ corresponding to a three dimensional integral cohomology class of a space X, there exist a "universal coefficient" isomorphism K_{*}^τ(X)\cong K_{*}(P_τ)\otimes_{K_{*}(\mathbb{C}P^{\infty})} \hat{K}_{*} where $P_τ$ is the total space of the principal $\mathbb{C}P^{\infty}$-bundle induced over X by $τ$ and $\hat K_*$ is obtained form the action of $\mathbb{C}P^{\infty}$ on K-theory.
Modello bayesiano per la riduzione dell'incertezza nella previsione delle piene del fiume Reno

description: Many efforts have been devoting since last years to reduce uncertainty in hydrological
modeling predictions. The principal sources of uncertainty are provided
by input errors, for inaccurate rainfall prediction, and model errors, given
by the approximation with which the water flow processes in the soil and river
discharges are described.
The aim of the present work is to develop a bayesian model in order to reduce
the uncertainty in the discharge predictions for the Reno river. The ’a priori’
distribution function is given by an autoregressive model, while the likelihood
function is provided by a linear equation which relates observed values of discharge
in the past and hydrological TOPKAPI model predictions obtained by the
rainfall predictions of the limited-area model COSMO-LAMI. The ’a posteriori’
estimations are provided throw a H∞ filter, because the statistical properties of
estimation errors are not known. In this work a stationary and a dual adaptive
filter are implemented and compared. Statistical analysis of estimation errors and
the description of three case studies of flood events occurred during the fall seasons
from 2003 to 2005 are reported. Results have also revealed that errors can be
described as a markovian process only at a first approximation.
For the same period, an ensemble of ’a posteriori’ estimations is obtained
throw the COSMO-LEPS rainfall predictions, but the spread of this ’a posteriori’
ensemble is not enable to encompass observation variability. This fact is related to
the building of the meteorological ensemble, whose spread reaches its maximum
after 5 days.
In the future the use of a new ensemble, COSMO–SREPS, focused on the
first 3 days, could be helpful to enlarge the meteorogical and, consequently, the
hydrological variability.

description: Interstellar dust plays an important role in the formation of molecular gas and the heating and cooling of the interstellar medium. The spatial distribution of the mm-wavelength dust emission from galaxies is largely unexplored. The NIKA2 Guaranteed Time Project IMEGIN (Interpreting the Millimeter Emission of Galaxies with IRAM and NIKA2) has recently mapped the mm emission in the grand design spiral galaxy NGC6946. By subtracting the contributions from the free-free, synchrotron, and CO line emission, we map the distribution of the pure dust emission at 1:15mm and 2mm. Separating the arm/interarm regions, we find a dominant 2mm emission from interarms indicating the significant role of the general interstellar radiation field in heating the cold dust. Finally, we present maps of the dust mass, temperature, and emissivity index using the Bayesian MCMC modeling of the spectral energy distribution in NGC6946.
