Year: 2010

description: In the last thirty years of the 20th century, a formidable numbers of scientific discoveries in the field of PIDs were made.  Many scientific papers have been published on the molecular and cellular basis of the immune response and on the mechanisms involved in the correct ontogeny of immune system components.  Today we know the genetic and molecular basis of the principal mechanisms involved in the immune response, thus it’s possible to classify immune diseases in different way, by different points of view.  In this thesis, during the three years of my PhD program, I tried to group the congenital immunodeficiencies on the basis of the altered immune function and on the basis of the cell type where the mutated genes are expressed in order to perform a novel characterization of such diseases through the combination of clinical, cellular, functional and molecular approaches.
In particular, my research work was focused on the study at both molecular and clinical levels of the Nude/SCID phenotype as the real human model of athymia in comparison with the DiGeorge syndrome which was erroneously considered for long time the human counterpart of the Nude murine model.
Moreover, in this context, I also participated to better define the functional role of FOXN1 transcription factor in the development of the pleiotropic aspects of the Nude/SCID syndrome.  From this study, FOXN1 emerged as a cofactor in the development and differentiation of some structures in the central nervous system.  Of note, these immunodeficiencies are due to mutated genes expressed in non hematopoietic cells.
In addition, I participated to the study of patients affected with Ataxia Telangiectasia (A-T) whose causing gene is not selectively expressed in the hematopoietic compartment and related to cerebellar functions.  In this context I contributed to evaluate whether the beneficial effect of betamethasone therapy in (A-T) patients could be mediated by interference in ROS generation/neutralization process.  Our research led to conclude that betamethasone response in A-T patients is inversely correlated to cerebellar atrophy and directly to antioxidative capacity.
During my PhD course I also participate to the study of some immunodeficiencies due to alterations of genes expressed in hematopoietic cells giving a contribution to the description of the mechanism altered in the case of high serum level of IgE.  The data obtained in this context revealed the alteration of IL-12R signaling in a group of patients with high levels of serum IgE but without Hyper IgE Syndrome.
Overall, all my studies were designed in order to better understand the mechanisms involved in the pathogenesis of such immune diseases.  The results of this thesis by adding novel information in this field could be useful both in the clinical practice and in the basic research of immune disorders by revealing unknown aspects of these diseases.

Effects of sulphate-deficiency on cysteine metabolism in the green alga Chlorella sorokiniana
Creators: name: Salbitani, Giovanna
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: Plants, bacteria and fungi have the ability to assimilate inorganic sulphur and incorporate it into inorganic compounds. Animals on the contrary, do not assimilate inorganic sulphur; they require methionine as an essential amino acid for their source of sulphur nutrient.
The amino acid cysteine (Cys) is the first committed molecule in plant metabolism containing sulphur and it is the sulphide donor for the generation of methionine, glutathione (GSH), phytochelatins, iron-sulphur clusters, vitamins, cofactors, and multiple secondary metabolites; that’s why the regulation of Cys-biosynthesis is critically important.
The aim of this research was to investigate the effects of  sulphur-deficiency on plant cysteine metabolism and to characterize the O-acetylserine(thiol)lyase (OASTL), a key-enzyme in cysteine biosynthesis.

description: Vehicular edge computing (VEC) is emerging as a promising architecture of vehicular networks (VNs) by deploying the cloud computing resources at the edge of the VNs. This work aims to optimize resource allocation and task offloading in VEC networks. Specifically, we formulate a game theoretical resource allocation and task offloading problem (GTRATOP) that aims to maximize the system performance by jointly considering the incentive for cooperation, competition among vehicles, heterogeneity between VEC servers and vehicles, and inherent dynamic of VNs. Since the formulated GTRATOP is NP-hard, we propose an adaptive approach for resource allocation and task offloading in VEC networks by incorporating bargaining game and matching game, which is called BARGAIN-MATCH. First, for resource allocation, a bargaining game-based incentive is proposed to stimulate the vehicles and VEC servers to negotiate the optimal resource allocation and pricing decisions. Second, for task offloading, a many-to-one matching scheme is proposed to decide the optimal offloading strategies. Third, the dynamic and time-varying features are considered to adapt the strategies of BARGAIN-MATCH to the real-time VEC networks. Moreover, the BARGAIN-MATCH is proved to be stable and weak Pareto optimal. Simulation results demonstrate that the proposed BARGAIN-MATCH achieves superior system performance and efficiency compared to other methods, especially when the system workload is heavy.

description: It is well known that attractive condensates do not posses a stable ground state in three dimensions. The widely used Gross-Pitaevskii theory predicts the existence of metastable states up to some critical number $N_{\mathrm{cr}}^{\mathrm{GP}}$ of atoms. It is demonstrated here that fragmented metastable states exist for atom numbers well above $N_{\mathrm{cr}}^{\mathrm{GP}}$. The fragments are strongly overlapping in space. The results are obtained and analyzed analytically as well as numerically. The implications are discussed.

description: The second quantum technological revolution started around 1980 with the control of single quantum particles and their interaction on an individual basis. These experimental achievements enabled physicists and engineers to utilize long-known quantum features - especially superposition and entanglement of single quantum states - for a whole range of practical applications. We use a publication set of 54,598 papers from the Web of Science published between 1980 and 2018 to investigate the time development of four main subfields of quantum technology in terms of numbers and shares of publication as well as the occurrence of topics and their relation to the 25 top contributing countries. Three successive time periods are distinguished in the analyses by their short doubling times in relation to the whole Web of Science. The periods can be characterized by the publication of pioneering works, the exploration of research topics, and the maturing of quantum technology, respectively. Compared to the US, China has a far over proportional contribution to the worldwide publication output, but not in the segment of highly-cited papers.

description: The HIgh-Time resolution (HIT) mode of FORS2 has 3 sub-modes that allow for imaging and spectroscopy over a range of timescales from milliseconds up to seconds. It is the only high time resolution spectroscopy mode available on an 8m class telescope. In imaging mode, it can be used to measure the pulse of pulsars and spinning white dwarfs in a variety of high throughput broad- and narrow-band filters. In spectroscopy mode it can take up to 10 spectra per second using a novel ''shift-and-wait'' clocking pattern for the CCD. It takes advantage of the user-designed masks which can be inserted into FORS2 to allow any two targets within the 6.8' x 6.8' field of view of FORS2 to be selected. A number of integration, or more precisely 'wait', times are available, which together with the high throughput GRISMs can observe the entire optical spectrum on a range of timescales.

description: The accuracy of the estimated stellar atmospheric parameter decreases evidently with the decreasing of spectral signal-to-noise ratio (SNR) and there are a huge amount of this kind observations, especially in case of SNR$<$30. Therefore, it is helpful to improve the parameter estimation performance for these spectra and this work studied the ($T_\texttt{eff}, \log~g$, [Fe/H]) estimation problem for LAMOST DR8 low-resolution spectra with 20$\leq$SNR$<$30. We proposed a data-driven method based on machine learning techniques. Firstly, this scheme detected stellar atmospheric parameter-sensitive features from spectra by the Least Absolute Shrinkage and Selection Operator (LASSO), rejected ineffective data components and irrelevant data. Secondly, a Multi-layer Perceptron (MLP) method was used to estimate stellar atmospheric parameters from the LASSO features. Finally, the performance of the LASSO-MLP was evaluated by computing and analyzing the consistency between its estimation and the reference from the APOGEE (Apache Point Observatory Galactic Evolution Experiment) high-resolution spectra. Experiments show that the Mean Absolute Errors (MAE) of $T_\texttt{eff}, \log~g$, [Fe/H] are reduced from the LASP (137.6 K, 0.195 dex, 0.091 dex) to LASSO-MLP (84.32 K, 0.137 dex, 0.063 dex), which indicate evident improvements on stellar atmospheric parameter estimation. In addition, this work estimated the stellar atmospheric parameters for 1,162,760 low-resolution spectra with 20$\leq$SNR$<$30 from LAMOST DR8 using LASSO-MLP, and released the estimation catalog, learned model, experimental code, trained model, training data and test data for scientific exploration and algorithm study.

description: We determine theoretically the relation between the total number of protons $N_{p}$ and the mass number $A$ (the charge to mass ratio) of nuclei and neutron cores with the model recently proposed by Ruffini et al. (2007) and we compare it with other $N_p$ versus $A$ relations: the empirical one, related to the Periodic Table, and the semi-empirical relation, obtained by minimizing the Weizsäcker mass formula. We find that there is a very good agreement between all the relations for values of $A$ typical of nuclei, with differences of the order of per cent. Our relation and the semi-empirical one are in agreement up to $A\sim 10^4$; for higher values, we find that the two relations differ. We interprete the different behaviour of our theoretical relation as a result of the penetration of electrons (initially confined in an external shell) inside the core, that becomes more and more important by increasing $A$; these effects are not taken into account in the semi-empirical mass-formula.

description: Many scientific problems focus on observed patterns of change or on how to design a system to achieve particular dynamics. Those problems often require fitting differential equation models to target trajectories. Fitting such models can be difficult because each evaluation of the fit must calculate the distance between the model and target patterns at numerous points along a trajectory. The gradient of the fit with respect to the model parameters can be challenging. Recent technical advances in automatic differentiation through numerical differential equation solvers potentially change the fitting process into a relatively easy problem, opening up new possibilities to study dynamics. However, application of the new tools to real data may fail to achieve a good fit. This article illustrates how to overcome a variety of common challenges, using the classic ecological data for oscillations in hare and lynx populations. Models include simple ordinary differential equations (ODEs) and neural ordinary differential equations (NODEs), which use artificial neural networks to estimate the derivatives of differential equation systems. Comparing the fits obtained with ODEs versus NODEs, representing small and large parameter spaces, and changing the number of variable dimensions provide insight into the geometry of the observed and model trajectories. To analyze the quality of the models for predicting future observations, a Bayesian-inspired preconditioned stochastic gradient Langevin dynamics (pSGLD) calculation of the posterior distribution of predicted model trajectories clarifies the tendency for various models to underfit or overfit the data. Coupling fitted differential equation systems with pSGLD sampling provides a powerful way to study the properties of optimization surfaces, raising an analogy with mutation-selection dynamics on fitness landscapes.

description: The polarized images of a synchrotron emitting ring are studied in the regular Hayward and Bardeen black hole spacetimes. These regular black holes carry a magnetic field in terms of gravity coupled to nonlinear electrodynamics. Results show that the main features of the polarization images of the emitting rings are similar in these two regular black hole spacetimes. As the magnetic charge parameter increase, the polarization intensity and the electric vector position angle in the image plane increase in Hayward and Bardeen black hole spacetimes. Moreover, the polarization intensity and electric vector position angle in the image of the emitting ring in the Hayward black hole spacetime are closer to those in the Schwarzschild case. The effects of the magnetic charge parameter on the Strokes $Q-U$ loops are also slightly smaller in the Hayward black hole spacetime. This information stored in the polarization images around Hayward and Bardeen black holes could help understand regular black holes and the gravity coupled to nonlinear electrodynamics.

description: Despite the success of the standard $Λ$CDM model of cosmology, recent data improvements have made tensions emerge between low- and high-redshift observables, most importantly in determinations of the Hubble constant $H_0$ and the (rescaled) clustering amplitude $S_8$. The high-redshift data, from the cosmic microwave background (CMB), crucially relies on recombination physics for its interpretation. Here we study how small-scale baryon inhomogeneities (i.e., clumping) can affect recombination and consider whether they can relieve both the $H_0$ and $S_8$ tensions. Such small-scale clumping, which may be caused by primordial magnetic fields or baryon isocurvature below kpc scales, enhances the recombination rate even when averaged over larger scales, shifting recombination to earlier times. We introduce a flexible clumping model, parametrized via three spatial zones with free densities and volume fractions, and use it to study the impact of clumping on CMB observables. We find that increasing $H_0$ decreases both $Ω_m$ and $S_8$, which alleviates the $S_8$ tension. On the other hand, the shift in $Ω_m$ is disfavored by the low-$z$ baryon-acoustic-oscillations measurements. We find that the clumping parameters that can change the CMB sound horizon enough to explain the $H_0$ tension also alter the damping tail, so they are disfavored by current Planck 2018 data. We test how the CMB damping-tail information rules out changes to recombination by first removing $\ell>1000$ multipoles in Planck data, where we find that clumping could resolve the $H_0$ tension. Furthermore, we make predictions for future CMB experiments, as their improved damping-tail precision can better constrain departures from standard recombination. Both the Simons Observatory and CMB-S4 will provide decisive evidence for or against clumping as a resolution to the $H_0$ tension.

description: Demand for animal sourced food is predicted to double in the upcoming 20 years in Sub-Saharan Africa. This is simultaneously a big opportunity in terms of poverty reduction and a significant threat to the environment. The objective of this paper is to present an approach to co-create a set of viable and acceptable development pathways for the livestock sector that maximizes benefits from increased production, exploits the synergies between livestock and the environment, while minimizing the negative effects. It engages local stakeholders and actors into a computer-assisted participatory process, through which local trade-offs and synergies between livestock production, livelihood benefits and environmental impacts can be explored. Scenarios reached by consensus among local stakeholders challenge the dominant discourse of livestock intensification. They suggest that combining extensive and intensive modes enables increased production of animal sourced food with lower additional pressure on the environment than current production modes. The right combination of extensive and intensive production allows for an efficient use of the local biomass and feed resources, and offers opportunities to improve livelihoods for all stakeholders despite their differing economic circumstances, values and traditions.
Water relations, survival and growth of conifer seedlings planted on a high elevation south-facing clearcut
Creators: name: Livingston, Nigel Jonathan
Publisher: name: University of British Columbia
Year: 2010

description: Equal numbers of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and Pacific silver fir (Abies amabilis (Doug.) Forbes) seedlings,,were spring planted, in 1981 and 1982, as 1-0 styroplugs on a south-facing high elevation clearcut located on Mount Arrowsmith, Vancouver Island, British Columbia. A number of treatments were applied to determine whether modification of seedling microclimate would increase survival and growth. These treatments included inclining the seedlings to the southwest, provision of shade cards, irrigation, and irrigation and shade cards combined. The highest survival rates, regardless of treatment, were exhibited by Douglas-fir. Approximately 72% and 82% of untreated seedlings, planted in 1981 and 1982 respectively, survived. Survival of seedlings that received treatment ranged from 81% to 95%. Douglas-fir seedlings were able to survive and grow because they were highly drought tolerant. Unirrigated seedlings lowered their osmotic potential by over 1.1 MPa in the course of a growing season in response to declining soil water potentials and consequently were able to maintain turgor. The transpiration rates of these seedlings were never less than 50% of those that were irrigated. Western hemlock, and to an even greater extent, Pacific silver fir seedlings lacked stress avoidance and tolerance mechanisms. Consequently there was very poor survival of both species. Survival rates were significantly increased by shade cards and irrigation but never exceeded 64% in either species. The extent and type of growth in all species was markedly affected by changes in microclimate. Irrigated seedlings developed the largest shoots and the smallest root systems. Shaded seedlings had larger shoots, but generally less roots, than untreated seedlings which had the lowest shoot to root dry mass ratios. A boundary-line analysis model that related seedling stomatal conductance (g[sub s]) to measurements of hourly average solar irradiance, air temperature, vapour pressure deficit and average root zone soil water potential, accounted for over 70% of the variability in g[sub s]. When the number of hours from sunrise was included as an independent variable, over 85% of the variability in g[sub s]could be explained. Measurements of seedling seasonal dry matter accumulation were better correlated with estimates of seedling growing season transpiration than with estimates of average growing season total seedling g[sub s].

description: Observations with space-borne X-ray telescopes revealed the existence of soft, diffuse X-ray emission from the inner regions of planetary nebulae. Although the existing images support the idea that this emission arises from the hot shocked central-star wind which fills the inner cavity of a planetary nebula, existing models have difficulties to explain the observations consistently. We investigate how the inclusion of thermal conduction changes the physical parameters of the hot shocked wind gas and the amount of X-ray emission predicted by time-dependent hydrodynamical models of planetary nebulae with central stars of normal, hydrogen-rich surface composition. The radiation hydrodynamical models show that heat conduction leads to lower temperatures and higher densities within a bubble and brings the physical properties of the X-ray emitting domain into close agreement with the values derived from observations. Depending on the central-star mass and the evolutionary phase, our models predict X-ray [0.45--2.5 keV] luminosities between $10^{-8}$ and $10^{-4}$ of the stellar bolometric luminosities, in good agreement with the observations. Less than 1% of the wind power is radiated away in this X-ray band. Although temperature, density, and also the mass of the hot bubble is significantly altered by heat conduction, the dynamics of the whole system remains practically the same. Heat conduction allows the construction of nebular models which predict the correct amount of X-ray emission and at the same time are fully consistent with the observed mass-loss rate and wind speed. Thermal conduction must be considered as a viable physical process for explaining the diffuse X-ray emission from planetary nebulae with closed inner cavities. Magnetic fields must then be absent or extremely weak.

description: This work proposes a Residual Recurrent Neural Network (RRNet) for synthetically extracting spectral information, and estimating stellar atmospheric parameters together with 15 chemical element abundances for medium-resolution spectra from Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). The RRNet consists of two fundamental modules: a residual module and a recurrent module. The residual module extracts spectral features based on the longitudinally driving power from parameters, while the recurrent module recovers spectral information and restrains the negative influences from noises based on Cross-band Belief Enhancement. RRNet is trained by the spectra from common stars between LAMOST DR7 and APOGEE-Payne catalog. The 17 stellar parameters and their uncertainties for 2.37 million medium-resolution spectra from LAMOST DR7 are predicted. For spectra with S/N >= 10, the precision of estimations Teff and log g are 88 K and 0.13 dex respectively, elements C, Mg, Al, Si, Ca, Fe, Ni are 0.05 dex to 0.08 dex, and N, O, S, K, Ti, Cr, Mn are 0.09 dex to 0.14 dex, while that of Cu is 0.19 dex. Compared with StarNet and SPCANet, RRNet shows higher accuracy and robustness. In comparison to Apache Point Observatory Galactic Evolution Experiment and Galactic Archaeology with HERMES surveys, RRNet manifests good consistency within a reasonable range of bias. Finally, this work releases a catalog for 2.37 million medium-resolution spectra from the LAMOST DR7, the source code, the trained model and the experimental data respectively for astronomical science exploration and data processing algorithm research reference.

description: This paper discovers that the neural network with lower decision boundary (DB) variability has better generalizability. Two new notions, algorithm DB variability and $(ε, η)$-data DB variability, are proposed to measure the decision boundary variability from the algorithm and data perspectives. Extensive experiments show significant negative correlations between the decision boundary variability and the generalizability. From the theoretical view, two lower bounds based on algorithm DB variability are proposed and do not explicitly depend on the sample size. We also prove an upper bound of order $\mathcal{O}\left(\frac{1}{\sqrt{m}}+ε+η\log\frac{1}η\right)$ based on data DB variability. The bound is convenient to estimate without the requirement of labels, and does not explicitly depend on the network size which is usually prohibitively large in deep learning.

The role of Methylglyoxal in the pathogenesis of endothelial insulin resistance and vascular damage
in type 2 diabetes
Creators: name: Nigro, Cecilia

description: It has now become evident that insulin exerts a direct action on vascular cells, thereby conditioning the outcome and progression of vascular complication associated with diabetes. However, the mechanisms through which insulin signaling is impaired in the vascular endothelium remain still unclear. Chronic hyperglycaemia per se promotes insulin resistance and plays a pivotal role in the outcome and progression of diabetes-associated vascular complications. Hyperglycaemia may act through different mechanisms, including generation of advanced glycation end products (AGEs). In this work we evaluated the role of the AGEs precursor methylglyoxal (MGO) in the generation of endothelial insulin-resistance in cellular and animal models.
Time-courses experiments were performed on bovine aortic endothelial cells (BAEC) incubated with different concentrations of MGO. The glyoxalase 1 inhibitor “SpBrBzGSHCp2” was used to increase the endogenous levels of MGO. For the in vivo study, C57bl6 mice were intraperitoneally injected with a MGO solution at steadily increasing concentrations (50 to 75mg/kg) for 7 weeks.
MGO incubation induces a 50% reduction of IRS1 phosphorylation, the loss of IRS1-p85 interaction and of the downstream Akt activation in response to insulin, whilst MAPK is more active in BAEC treated with MGO. The insulin-induced Akt activation is reverted by the inhibition of ERK through the use of MEK inhibitor U0126 in BAEC treated with MGO. Furthermore, downstream Akt, MGO is able to inhibit eNOS activation in response to insulin, and this was paralleled by a 60% decrease of insulin-induced NO production in BAEC. Similar results were obtained in BAEC treated with SpBrBzGSHCp2 compared to controls. Intraperitoneally administration of MGO to mice caused insulin resistance (ITT AUC: C57MGO 10163±1979 vs C57 7787±1174 mg/dl/120’, p=0.01) and reduced serum NO by 2.5-fold compared to untreated mice. Western blots of lysates of aortae from MG-treated mice revealed a reduction of insulin-induced Akt activation.
In conclusion, this work shows that MGO impairs insulin signaling in endothelial cells and insulin effect on endothelial NO production both in vitro and in vivo. A possible role in these effects may be played by ERK. Further investigations of the molecular mechanisms by which hyperglycaemia compromises insulin action in vascular cells may allow to develop new strategies to preserve endothelial function in diabetic subjects.
Leading Order Calculation of Shear Viscosity in Hot Quantum Electrodynamics from Diagrammatic Methods

description: We compute the shear viscosity at leading order in hot Quantum Electrodynamics. Starting from the Kubo relation for shear viscosity, we use diagrammatic methods to write down the appropriate integral equations for bosonic and fermionic effective vertices. We also show how Ward identities can be used to put constraints on these integral equations. One of our main results is an equation relating the kernels of the integral equations with functional derivatives of the full self-energy; it is similar to what is obtained with two-particle-irreducible effective action methods. However, since we use Ward identities as our starting point, gauge invariance is preserved. Using these constraints obtained from Ward identities and also power counting arguments, we select the necessary diagrams that must be resummed at leading order. This includes all non-collinear (corresponding to 2 to 2 scatterings) and collinear (corresponding to 1+N to 2+N collinear scatterings) rungs responsible for the Landau-Pomeranchuk-Migdal effect. We also show the equivalence between our integral equations obtained from quantum field theory and the linearized Boltzmann equations of Arnold, Moore and Yaffe obtained using effective kinetic theory.

description: A laser ablation ion source (LAS) is a powerful tool by which diverse species of ions can be produced for mass spectrometer calibration, or surface study applications. It is necessary to frequently shift the laser position on the target to selectively ablate materials in a controlled manner, and to mitigate degradation of the target surface caused by ablation. An alternative to mounting the target onto a rotation wheel or $x-y$ translation stage, is to shift the laser position with a final reflection from a motorized kinematic mirror mount. Such a system has been developed, assembled and characterized with a two axis motorized mirror and various metal targets. In the system presented here, ions are ablated from the target surface and guided by a 90 degree quadrupole bender to a Faraday cup where the ion current is measured. Spatially resolved scans of the target are produced by actuating the mirror motors, thus moving the laser spot across the target, and performing synchronous measurements of the ion current to construct 2D images of a target surface which can be up to 50~mm in diameter. The spatial resolution of the system has been measured by scanning the interfaces between metals such as steel and niobium, where it was demonstrated that the LAS can selectively ablate an area of diameter $\approx$50 $μ$m. This work informs the development of subsequent LAS systems, that are intended to serve as multi-element ion sources for commercial and custom-built time-of-flight mass spectrometers, or to selectively study surface specific regions of samples.

description: This work presents a speech intonation processing method based on phonetic syllables and optimal pitch stylization and applied to dimensional and continuous emotion tracking. After presenting the automatic segmentation and stylization algorithms, experiments performed on emotional speech corpora show that results are competitive with the state of the art on dimensional emotion recognition and that continuous tracking is stable for the Activation axis.

description: The motion of a Dp-brane in the background of a stack of coincident NS5-branes is analysed as the motion of a relativistic point particle in the transverse space of the five-branes. In this system, the particle experiences a proper acceleration orthogonal to its proper velocity due to the background dilaton field which changes the dynamics from that of a simple geodesic motion. In particular, we show that in the vicinity of the five-branes, it is this acceleration which is responsible for modifying the motion of the radial mode to that of an inverted simple harmonic oscillator leading to the tachyonic instability.
